How to Keep Your House Cool in Summer: A Tyler Homeowner’s Guide

/

If you have lived through even one East Texas summer, you already know the assignment. Learning how to keep your house cool in summer here in Tyler is not just about comfort, it is about staying ahead of the heat and humidity that settle over our part of the state from late May well into September. The air gets thick, the dew points climb, and your air conditioner ends up working harder than folks in drier climates ever have to think about. The good news is that a cool, comfortable home is well within reach when you understand what your system is up against and how to give it a hand. This guide walks you through the practical steps that actually make a difference, from the thermostat on your wall to the condenser sitting out in the yard. Why It Is Hard to Keep Your House Cool in Summer in East Texas Summer in Tyler and the surrounding towns like Lindale, Whitehouse, Bullard, and Flint is defined by two things working together: heat and humidity. It is one thing to cool down hot, dry air. It is another thing entirely to pull moisture out of thick, muggy air day after day. Your air conditioner does not just lower the temperature in your home, it removes humidity as warm indoor air passes over the cold evaporator coil. When the air outside is heavy with moisture, your system spends a large chunk of its energy just wringing that water out before your rooms ever start to feel comfortable. On top of the humidity, East Texas throws in a few extra challenges. We get long stretches of afternoon thunderstorms that spike the moisture even higher, then clear out and leave the sun beating down on your roof and outdoor unit. We are surrounded by pine, so pollen and needles are a constant during the growing season, and all of that debris loves to collect in and around your equipment. A system that would coast along in a milder, drier part of the country has to grind through real conditions here. That is exactly why a little seasonal attention pays off so well. How to Keep Your House Cool in Summer Starting With Your Thermostat The single easiest place to start is the device already on your wall. A lot of homeowners fight their comfort by constantly cranking the thermostat up and down, which usually makes things worse. Your air conditioner cools at a steady pace. It cannot blast a hot house cold in ten minutes just because you set the number lower, and setting it far below where you actually want it only runs the system harder without getting you there any faster. Pick a comfortable setpoint for when you are home and awake, then let the system hold it. A programmable or smart thermostat helps enormously because it can let the house drift a few degrees warmer while you are away at work, then bring it back to a comfortable temperature before you walk in the door. ENERGY STAR explains that certified smart thermostats can automatically adjust your home’s heating and cooling settings to support better energy performance. That small daily rhythm reduces total runtime without ever leaving you sweating. Just be reasonable with how far you let the temperature climb during the day. In our climate, letting a home get extremely warm and humid while you are gone means your AC has to fight both the heat and all the moisture that crept back in, which can reduce the savings you were hoping for. How to Keep Your House Cool in Summer With Ceiling Fans Ceiling fans are one of the most underused tools for staying cool. A fan does not lower the air temperature. Instead, it moves air across your skin so you feel cooler through evaporation. The U.S. Department of Energy notes that using a ceiling fan can help you stay comfortable at a higher thermostat setting. That means you may be able to reduce some of the strain on your air conditioner while remaining comfortable. Two things matter here. First, make sure your fans are spinning counterclockwise in summer so they push air down and create a breeze. Second, turn fans off in empty rooms. Fans cool people rather than rooms, so leaving one running in an empty bedroom only uses energy without making anyone more comfortable. Block Outdoor Heat to Keep Your House Cool in Summer Every bit of heat you keep out of the house is heat your air conditioner never has to remove. In our sun-heavy summers, controlling how much heat enters through your windows, roof, and walls makes a bigger difference than most people expect. Windows, Blinds, and Curtains South and west facing windows take a beating from the afternoon sun, especially during those long, bright stretches between thunderstorms. Closing blinds or curtains on the sunniest sides of the house during the hottest part of the day blocks a surprising amount of radiant heat. Light-colored or thermal-lined curtains help even more. If you have rooms that turn into ovens by mid-afternoon, that is where to focus first. Attic Insulation and Weatherstripping Your attic is where summer heat builds up the most, and if your insulation is thin or unevenly spread, that heat radiates straight down into your living space. Good attic insulation acts like a blanket that keeps the roof heat from taking over your rooms. It is worth having a professional look at your attic if the upstairs or back rooms of your home never seem to cool down the way the rest of the house does. Then there are all the small gaps. Weatherstripping around doors and caulking around windows seal up the little leaks where cooled air escapes and hot, humid outdoor air sneaks in. You would be amazed how much conditioned air slips out through a poorly sealed exterior door over the course of a Texas summer. Sealing those leaks keeps the humidity you worked so hard to remove

AC Freezing Up? Causes, Fixes & When to Call a Pro

/

When your AC is freezing up in the middle of a hot Texas summer, it’s more than just frustrating—it’s a sign that something’s preventing your system from working properly. Ice forming on your indoor coil, refrigerant lines, or around your evaporator might seem odd when you’re trying to cool your home. However, it’s actually a common issue we see throughout Tyler. The good news is that a frozen air conditioner isn’t a lost cause. In many cases, the underlying problem can be repaired once properly diagnosed. Because a frozen system can’t cool your home effectively and may even cause serious damage if ignored, understanding what’s happening is essential. Knowing when to call for professional help protects both your comfort and your investment. We’re here to walk you through the warning signs, the most common causes, and why timely AC repair matters. Why Is My AC Freezing Up? When you notice ice forming on your air conditioning unit, it’s not normal. It’s definitely not helping keep your Tyler home cool during our hot, humid summers. Ice on your AC is actually a warning sign that something is preventing your system from working correctly. We see this problem frequently. Understanding why it happens can help you recognize when it’s time to call our team at C&R Services for professional help. The root cause usually comes down to temperature and airflow. Your evaporator coil is designed to get cold as refrigerant passes through it. However, it needs constant warm air flowing across it to maintain the right balance. When airflow is reduced by dirty filters or blocked vents, condensing coils become too cold, causing condensation to freeze. In Tyler’s climate, where we run our systems hard for months on end, restricted airflow can quickly turn normal condensation into a solid block of ice. Low refrigerant levels, thermostat problems, and drainage issues can also create the conditions for freezing. If you’re experiencing ac freezing up due to restricted airflow, replacing your filter and clearing blocked vents can sometimes help prevent the problem from worsening. If you spot ice anywhere on your AC system, the safest next step is to turn off your unit. Then contact us right away. We’ll diagnose exactly what’s causing the freeze-up and restore proper operation before the ice damages your compressor or other expensive components. Signs Your AC Is Freezing Up Recognizing the warning signs of a frozen air conditioner early can save you from costly damage. It also prevents uncomfortable summer days here in Tyler. The most obvious indicator is visible ice or frost buildup on your outdoor unit’s refrigerant lines or around the indoor evaporator coil. You might also notice water pooling around your indoor air handler as ice melts. This can potentially damage floors, ceilings, or walls. Performance symptoms are just as telling. If your home isn’t cooling despite the system running constantly, ice may be blocking proper circulation. You might also notice weak airflow from your vents. Some homeowners hear hissing sounds or notice their unit cycling on and off more frequently than normal. Running an AC with frozen coils may cause irreparable harm to the cooling system, so the unit must be turned off immediately if you suspect freezing. Whether you’re dealing with ac freezing up in the summer heat or noticing reduced performance during peak cooling season, these warning signs should never be ignored. When you spot any of these signs, don’t wait. Turn off your system and call us at C&R Services right away. We’ll diagnose the root cause, whether it’s airflow restriction, refrigerant issues, or another underlying problem. Then we’ll restore safe, efficient operation before permanent damage occurs. Common Causes of a Frozen AC Unit When we diagnose an AC freezing up, we’re looking for three primary culprits. These disrupt the delicate balance your system needs to operate safely. The most common issue is restricted airflow—whether from a clogged filter, blocked return vents, or a failing blower motor. When air can’t move freely across the evaporator coil, the refrigerant inside becomes too cold. In a properly functioning system, that coil should stay cold but not frozen. The refrigerant should stay at about 40°F to efficiently pull heat from the air passing over it. Without enough warm air to absorb, ice forms quickly. The second major cause is low refrigerant due to a leak in the system. When refrigerant levels drop, pressure inside the coil falls. This causes temperatures to plummet below freezing. Finally, thermostat malfunctions or a system running too long in cooling mode can push the coil past its safe operating temperature. Each instance of ac freezing up we encounter typically involves at least one of these issues, and sometimes a combination of multiple factors working together to create the freeze condition. We use specialized gauges and diagnostic tools to pinpoint which factor—or combination of factors—is causing your freeze-up. Because these issues involve sealed refrigerant systems, electrical components, and airflow dynamics, accurate diagnosis requires licensed expertise. If you’re seeing ice, call C&R Services so we can identify the root cause and restore safe operation. What Happens If You Keep Running a Frozen AC? Ignoring a frozen air conditioner and continuing to run it can lead to serious and expensive damage. When ice builds up on the evaporator coil, your system has to work much harder to push air through the blockage. This puts enormous stress on the compressor—the heart of your AC system. The compressor can overheat and fail completely. Compressor replacement is one of the most costly HVAC repairs. In some cases, it makes more financial sense to replace the entire system rather than just the compressor. Beyond compressor failure, operating a frozen unit can cause refrigerant line damage. It can also lead to motor burnout and even electrical issues throughout the system. The longer you run it, the more components are at risk. We’ve seen homeowners turn a simple issue—like restricted airflow or low refrigerant—into a catastrophic system failure. This happens simply by leaving the AC on and

Ceiling Fan Direction for Summer: Save Energy & Stay Cool

/

Summer in East Texas brings scorching heat. Your air conditioner works overtime to keep your home comfortable. But did you know that setting your ceiling fan direction for summer correctly can actually help your AC work more efficiently? We’ve noticed that many homeowners don’t realize their ceiling fans have a switch that changes the blade rotation. Using it properly can make your home feel several degrees cooler without touching the thermostat. At C&R Services, we want to help you stay comfortable while keeping your energy bills under control. So let’s talk about how to optimize your ceiling fans for the hot Texas summer. Understanding How Ceiling Fan Direction Affects Your Comfort in the Summer Ceiling fans don’t actually lower the temperature in a room. Instead, they create air movement that makes you feel cooler through something called the wind chill effect. When air moves across your skin, it helps moisture evaporate. This makes you feel up to 8 degrees cooler than the actual room temperature. That’s why the direction your ceiling fan spins matters so much during summer months. Most ceiling fans have a small switch on the motor housing that reverses the blade direction. During summer, fan blades should spin counterclockwise when you look up at them from below. This direction pushes air straight down. As a result, it creates that refreshing breeze that cools your skin. In fact, this downward airflow is exactly what you need when temperatures climb into the triple digits here in West Texas. How to Check Whether Your Ceiling Fan Direction Is Set Correctly for Summer When your ceiling fan is on at a medium or high speed, you should feel a strong breeze blowing down on you. This happens when you stand directly beneath it. The blades should be moving counterclockwise. The leading edge of each blade should move from your right to your left as you watch from below. If you’re not feeling much air movement or the breeze feels weak even on high speed, your fan is likely spinning clockwise. That’s the winter setting. If you’re unsure about adjusting your ceiling fan direction for summer, we can help. Also, if the switch seems difficult to access, a certified C&R Services technician can quickly verify and adjust the setting for you during a routine service call. We can also inspect the fan to ensure it operates safely and efficiently. When You Need Professional Help With Your Fan Ceiling fans involve both electrical connections and mounting hardware. Therefore, any adjustments beyond basic observation should be handled carefully. If you’re uncomfortable accessing the motor housing, your C&R Services professional will help. Similarly, if your fan is located in a difficult-to-reach area, we’ll ensure the direction is set correctly for the season. We prioritize safety and proper operation in every service we provide. How Proper Ceiling Fan Direction in Summer Can Save Energy When ceiling fans blow downward in summer, you can often raise your thermostat by 4 degrees without sacrificing comfort. That might not sound like much. However, each degree you raise your thermostat can reduce your cooling costs by about 3-5%. Over a long East Texas summer, those savings really add up on your electricity bill. We’ve seen countless homes where families were running their AC at 68 degrees and still feeling uncomfortable. This happened because their ceiling fans were set to the winter direction. Once we helped them switch the fans to summer mode, they could bump the thermostat up to 72 degrees and feel even more comfortable. As the U.S. Department of Energy explains, ceiling fans create a wind chill effect that can help you feel cooler without lowering the thermostat even more. Combined with conditioned air, that can be far more efficient than simply cranking the AC down. But of course, if your thermostat isn’t responding correctly, comfort problems may have nothing to do with your fan direction. Ceiling Fans Work Best in Occupied Rooms Here’s something important to remember: ceiling fans cool people rather than rooms. Therefore, you should turn them off when you leave. A fan running in an empty room just wastes electricity without providing any benefit. Some of our customers install ceiling fans with remote controls or smart switches. This way, they can easily turn them off from anywhere in the house. When Ceiling Fans Need Professional Attention Sometimes homeowners discover issues when they start paying attention to their ceiling fan direction. If your fan wobbles excessively, makes grinding or clicking noises, or doesn’t produce much airflow even on high speed, it might need service or repair. Ceiling fan problems often come from loose mounting brackets. They can also result from unbalanced blades, worn bearings, or electrical issues. A licensed professional should handle ceiling fan repairs. Ceiling fans involve both electrical connections and mounting hardware that must be installed correctly for safety. At C&R Services, we regularly service ceiling fans as part of our commitment to helping East Texas homeowners stay comfortable. Whether you need a new fan installed, an existing fan repaired, or help optimizing your home’s overall cooling strategy, we’re here to serve you. We provide the expertise and faith-driven service that defines our team. Signs Your Ceiling Fan Needs Professional Service Pay attention to unusual sounds coming from your ceiling fan. Watch out especially for grinding, humming, or clicking that wasn’t there before. These noises often show worn bearings or loose components that need attention. Similarly, if your fan wobbles more than a slight wiggle, the mounting bracket might be loose. The blades could also be unbalanced. A severely wobbling fan can eventually damage your ceiling or even fall. So don’t ignore this warning sign. Another red flag is inconsistent speed control. Your fan might only work on one speed regardless of the setting. It might also randomly change speeds on its own. In these cases, you likely have an electrical issue with the switch or capacitor. These problems require a certified technician who can safely diagnose and repair the electrical components.

Furnace Not Turning On? Here’s What to Check First

/

If you’ve found yourself dealing with a furnace not turning on in the middle of a cold morning, you’re not alone. As someone who’s worked on heating systems for years here at C&R Services, I’ve seen this exact issue pop up more times than I can count. It’s frustrating—but the good news is, it’s often something simple. Before you panic or call for emergency service, there are a few things you can safely check yourself. Common Reasons Your Furnace Is Not Turning On These are the most frequent causes I see in the field when homeowners call about their furnace not turning on. Start with the easy ones—you might save yourself a service call. 1. Furnace Not Turning On? Check the Thermostat Settings Let’s start with the obvious, because it really does happen: the thermostat. Make sure it’s set to “heat” and that the temperature is higher than the current room reading. It sounds simple, but I’ve walked into homes where the system was perfectly fine—the thermostat just wasn’t communicating correctly. If your thermostat runs on batteries, swap them out. Weak batteries can cause the unit to lose its signal to the furnace. Also, if it’s a smart thermostat, check the Wi-Fi connection and any scheduling settings that might delay the heating cycle. If you’re unsure how to change your system’s mode, here’s a quick guide on switching your AC to heat properly that walks you through the process step by step. (Technician tip: sometimes, simply switching the system to off for 30 seconds and turning it back on resets everything.) 2. Inspect the Furnace Power Switch and Breaker When your furnace not turning on has you stumped, check the power first. There’s usually a wall switch near the furnace that looks like a regular light switch—it controls the power to the unit. Make sure it’s in the “on” position. Next, head to your electrical panel. If the furnace breaker is tripped, reset it once. If it trips again, that could signal an electrical short or internal issue that needs professional attention from C&R Services. 3. Look at the Furnace Filter A dirty air filter is one of the most common reasons for furnace problems. When the filter clogs, it restricts airflow and can cause the system to overheat and shut down as a safety measure. Pull the filter out and hold it up to the light. If you can’t see through it, replace it. Regular filter changes—every one to three months depending on usage—can prevent your furnace not turning on and save energy at the same time. For guidance on keeping your heating system efficient, the U.S. Department of Energy’s fall and winter energy-saving tips recommend checking your furnace filter monthly and replacing it when it’s dirty to maintain proper airflow and performance. 4. Inspect the Pilot Light or Ignition System If you have an older gas furnace, check the pilot light. It should burn a steady blue flame. If it’s out, follow your manufacturer’s relighting instructions carefully. For newer high-efficiency systems, look for electronic ignition issues instead. These models use flame sensors and hot surface igniters that can fail or get dirty over time. If you’re not comfortable checking these components, it’s best to call a certified technician at C&R Services to handle it safely. And if you’re unsure how the full heating cycle works—or how your furnace is supposed to ignite and produce warm air—our guide on how a furnace heats your home breaks down the entire process in clear, simple steps. 5. Check for Blocked Vents or Air Intakes Sometimes, the problem isn’t inside the furnace—it’s outside. Snow, debris, or even leaves can block the air intake or exhaust vent on modern systems, triggering safety sensors that stop the furnace from firing. Take a walk around the exterior of your home and make sure those PVC pipes are clear. A quick cleanup could be the difference between no heat and a warm, cozy night. 6. Listen for Unusual Noises or Smells When troubleshooting a furnace not turning on, your senses can tell you a lot. If you hear clicking but no ignition, the problem might lie with the igniter or gas valve. A burning smell after startup can signal dust burning off—but if it persists or smells like gas, turn off the system and call for help immediately. For gas-related safety info, see the U.S. Consumer Product Safety Commission’s furnace and home heating tips. It’s always better to err on the side of caution. 7. When to Call a Professional If you’ve checked everything and your furnace not turning on still has you puzzled, it’s time to bring in a professional. Issues like faulty control boards, bad blower motors, or cracked heat exchangers aren’t DIY-friendly and can pose safety risks. At C&R Services, we handle all kinds of heating repair and diagnostic work. Whether it’s an electrical fault, a gas flow issue, or a sensor problem, we’ll get to the root of it quickly. And we always check for safety hazards like carbon monoxide leaks during every service call. If your furnace is older and this isn’t its first hiccup, it might be nearing the end of its lifespan. Learn more about how long furnaces typically last before replacement so you can plan ahead and avoid sudden breakdowns. Keep Your Furnace Running Smoothly Routine maintenance can prevent most situations that result in a furnace not turning on. Schedule seasonal tune-ups before winter hits. We inspect igniters, test safety switches, clean flame sensors, and verify gas pressure. These steps keep your furnace efficient and reliable when you need it most.

How Long Do Furnaces Last? Lifespan, Signs, and Tips

/

If you’re wondering how long furnaces last, you’re not alone. We hear this question from homeowners all the time—especially when temperatures start to dip and heating bills go up. The truth is, most people don’t think about their furnace until something goes wrong. But knowing the average lifespan of a furnace, plus what affects it, can help you plan ahead and avoid surprise breakdowns. At C&R Services, we’ve worked on thousands of heating systems, and we’ve learned what really makes the difference between a short-lived unit and one that runs strong for years. Let’s dive into what affects furnace lifespan, signs yours may be near the end, and how to get the most out of your system. How Long Do Furnaces Last on Average? In general, the average gas furnace lasts between 15 to 20 years. Electric furnaces can sometimes stretch to 20–30 years, but they usually cost more to run. High-efficiency systems might not last quite as long due to more complex components—but they’ll save you money on energy bills in the meantime. That said, those are just averages. We’ve seen some furnaces in great shape at 25 years, and others on their last leg at 10. It all depends on how the system was installed, maintained, and used. Most homes today use a forced air heating system, which moves warm air through ducts and vents. If you’d like to learn more, check out our post on what forced air heating is and how it works. And if you want a clearer breakdown of how a furnace actually creates heat and moves air through the home, our guide on how a furnace works walks through the full process step-by-step. What Determines How Long Furnaces Last? Here’s what we’ve seen over and over again in the field: 1. Maintenance Schedule Annual maintenance is the single biggest factor. A neglected furnace will wear out faster, no matter how well it was built. Regular tune-ups catch small issues before they turn into major problems. (Think of it like changing the oil in your car.) ENERGY STAR offers a helpful maintenance checklist that outlines what a full furnace service should include. 2. Airflow and Filter Changes Clogged filters strain your blower motor and reduce efficiency. Changing filters every 1–3 months (depending on usage and filter type) makes a noticeable difference. We always recommend setting a reminder on your phone—it’s easy to forget. 3. Proper Installation Even the best furnace won’t last if it was poorly installed. Undersized or oversized systems wear down quickly, and poor ductwork can force the system to work harder than it should. That’s why we always emphasize proper sizing and layout design at C&R Services. 4. Local Climate and Usage Colder climates naturally put more stress on a furnace. If your system runs daily for 6+ months a year, it’s doing more work—and that adds up. That’s also why it’s smart to plan ahead if you live in a region with harsh winters. Signs Your Furnace Is Near the End Even if your furnace is still running, there are a few telltale signs it may be time to start thinking about a replacement: Rising heating bills despite normal usage Frequent repairs in the last 2–3 years Strange noises like banging, rattling, or humming Uneven heating throughout the house System age over 15 years You don’t have to panic—but if you’re seeing two or more of these signs, it’s time for an inspection. Learn more about our furnace services to see how C&R Services can help keep your system running safely and efficiently. We’ve helped a lot of homeowners weigh the cost of repairs versus replacement, and sometimes, a new furnace is the more cost-effective option long term. How Long Do Furnaces Last Without Regular Maintenance? If you’ve been skipping annual tune-ups, trust me—it’s more common than you think, but it really affects how long furnaces last. Without proper care, dirt buildup, worn parts, and airflow issues can shorten a furnace’s lifespan by several years. At C&R Services, we’ve seen well-built systems fail early simply because they went too long without service. On the flip side, we’ve seen units over 20 years old still running strong thanks to consistent maintenance. Regular inspections keep efficiency high, reduce wear, and prevent those surprise mid-winter breakdowns nobody wants. If you’re not sure when your furnace was last checked, that’s your cue to schedule a visit. It’s one of the simplest ways to extend how long your furnace lasts. How Long Do Furnaces Last? Final Thoughts from the Field In our experience at C&R Services, how long furnaces last depends on the decisions you make early on—installation, maintenance, and daily use all play a role. But even with the best care, no furnace lasts forever. Knowing when it’s time to start planning for a replacement can help you avoid emergencies, keep your home comfortable, and make smart financial choices. If you’re not sure where your furnace stands, we’d be happy to take a look and give you an honest assessment. Whether you need routine service or you’re ready for something new, our team’s here to help. Contact C&R Services today to schedule a furnace inspection or consultation.

How to Switch Your AC to Heat: Step-by-Step Guide

/

When the weather starts changing, it’s easy to forget that your HVAC system needs a little adjustment too. Every fall, we get calls from homeowners wondering how to switch from AC to heat without accidentally triggering an error code or blowing cold air. Trust us — it happens more often than you’d think. At C&R Services, we help families make the transition every year, and the good news is that it’s usually a simple process once you know what to check. Understanding How Your System Switches from AC to Heat Before you start flipping switches or pushing buttons, it helps to know what’s happening inside your system. When you switch from AC to heat, your thermostat signals your indoor and outdoor units to reverse their roles. Instead of pulling warm air out of your home, your heat pump or furnace begins generating warmth and distributing it through your ducts. (Quick tip—many homeowners forget to change their thermostat setting from Cool to Heat. It sounds obvious, but we’ve seen seasoned homeowners miss it after a long summer.) According to the U.S. Department of Energy, setting and programming your thermostat correctly can improve both comfort and efficiency. That means fewer surprises when temperatures swing overnight. Step 1: Set Your Thermostat to Heat Mode The first step in switching from AC to heat is updating your thermostat. Most modern thermostats have clearly labeled Cool, Heat, and Auto settings. If your system doesn’t respond immediately, don’t panic—it can take a minute for the system to recalibrate. For smart thermostats, double-check your app or schedule settings to make sure the system won’t automatically revert back to cooling mode. We’ve had more than one customer think their system was broken when it was just following a programmed schedule. Step 2: Adjust the Temperature Gradually When Going from AC to Heat When you move your system from AC to heat, avoid setting the temperature 10 degrees higher all at once. A gradual adjustment—say two or three degrees at a time—helps the system switch smoothly and reduces strain. This small change can extend the life of your components and prevent uneven heating across your home. Step 3: Listen and Observe After Switching from AC to Heat Once you’ve made the switch, stand near your vents and listen. You should hear a gentle hum or soft airflow within a few minutes. If you hear metallic clanks, buzzing, or smell burning dust, don’t worry right away—some odor is normal when the heating elements warm up for the first time in months. However, if it lingers, it’s worth calling a technician to take a look. At C&R Services, we always tell customers: trust your senses. If something sounds or smells off, there’s probably a reason. Step 4: Check Airflow and Filters When you go from AC to heat, airflow becomes even more important. Dirty or clogged filters restrict warm air and can trigger system shutdowns or short cycles. Replace your filters at the start of the season or at least every 90 days. For better indoor air quality and efficiency, most HVAC pros recommend using filters with a MERV-13 rating or higher—if your system can handle it. According to ASHRAE’s guidelines, airflow and system capacity should always be factored in when upgrading your filter. Step 5: Test Your Heat Pump or Furnace If your system includes a heat pump, switching from AC to heat is as simple as flipping the mode on your thermostat. The reversing valve changes direction automatically. But if you have a gas furnace, you’ll want to ensure your pilot light or ignition system is working correctly before you rely on it full-time. And if you need a clearer explanation of how a furnace generates heat, ignites, and pushes warm air through the home, our furnace guide walks through the entire process. We’ve had homeowners call in panic when they smell that first puff of dust burning off the coils—it’s totally normal. That smell usually disappears after a few minutes of running the heat. However, if your furnace won’t ignite or keeps blowing cold air, it’s time to schedule professional heating repair. When to Call a Professional If your thermostat doesn’t respond, your vents stay cold, or your breaker keeps tripping, it’s time to call for help. Sometimes, the problem is minor—like a loose wire or blocked intake. But it can also point to something more serious, such as a failed heat pump valve or dirty sensors. C&R Services handles all types of HVAC issues, and our team can make sure your system transitions safely and efficiently between seasons. Keep Your System Ready for Every Season Making the switch from AC to heat isn’t complicated, but it’s one of those small tasks that can make a big difference in comfort and reliability. Your cooling system worked hard all summer, so now’s the perfect time to shift focus to heating maintenance before cooler weather sets in. And when spring rolls around again, don’t forget to schedule your AC maintenance to keep both systems running at their best year-round.
