Spring HVAC Maintenance Checklist: Preparing Your System for Warmer Weather in Lexington, SC

March 26, 2024

As the temperatures start to rise in Lexington, SC, it's time to transition your HVAC system from heating to cooling mode. Spring is the perfect time to give your HVAC system some much-needed attention and ensure it's ready to keep you cool and comfortable during the warmer months ahead. In this blog, Brian's Heating & Cooling, your trusted HVAC contractor in Lexington, SC, will provide a comprehensive spring HVAC maintenance checklist to help you prepare your system for the upcoming season.


*1. Change Air Filters

Start by replacing the air filters in your HVAC system. Clean air filters promote better airflow, improve indoor air quality, and help your system operate more efficiently. For homes with pets or allergies, consider using high-efficiency filters for optimal filtration.


*2. Inspect and Clean Outdoor Unit

Check the outdoor condenser unit for any debris, such as leaves, grass clippings, or dirt, that may have accumulated during the winter months. Clear away any obstructions and gently clean the unit with a hose to ensure proper airflow and efficient operation.


*3. Inspect Ductwork for Leaks

Inspect the ductwork in your home for any signs of leaks or damage. Leaky ducts can waste energy and compromise indoor comfort. Seal any leaks with duct mastic or foil tape to improve efficiency and prevent conditioned air from escaping.


*4. Check Refrigerant Levels

Ensure that your air conditioning system has the correct refrigerant levels for optimal performance. Low refrigerant levels can indicate a leak or other issues that may need professional attention. Schedule a maintenance visit with our team to inspect and recharge refrigerant as needed.


*5. Clean Vents and Registers

Vacuum or dust the vents and registers throughout your home to remove any accumulated dust or debris. Clean vents promote better airflow and distribution of conditioned air, ensuring consistent comfort in every room.


*6. Test Thermostat Settings

Test your thermostat to ensure it's functioning correctly and accurately reading indoor temperatures. Consider upgrading to a programmable or smart thermostat for added convenience and energy savings.


*7. Schedule Professional Maintenance

Finally, consider scheduling a professional maintenance visit with our team. Our experienced technicians will perform a thorough inspection, cleaning, and tune-up of your HVAC system to ensure it's operating at peak efficiency and reliability for the warmer months ahead.


By following this spring HVAC maintenance checklist, you can ensure that your HVAC system is ready to tackle the warmer weather and keep you comfortable all season long in Lexington, SC.

Top 5 HVAC Repairs We’re Seeing in Lexington This Summer

July 17, 2025
Summer is in full swing here in Lexington, SC, and that means your air conditioning system is working harder than ever. With the combination of high heat, humidity, and constant usage, HVAC issues are more common this time of year—and we’ve been busy helping homeowners across the area stay cool and comfortable. Here are the top 5 HVAC repairs we’re seeing this summer, and what you can do to avoid them. 1. Refrigerant Leaks Low refrigerant levels are one of the most common summer problems we see. Over time, small leaks can develop in the system, leading to reduced cooling, longer run times, and increased energy bills. Signs to watch for: Warm air blowing from vents AC running nonstop Hissing or bubbling sounds near the outdoor unit Our fix: We locate and seal the leak, recharge your system with the correct amount of refrigerant, and make sure everything is running at peak efficiency. 2. Clogged Condensate Drain Lines Lexington’s humidity causes your AC to remove a lot of moisture from the air. That water drains through a condensate line, which can become clogged with algae or debris, leading to water damage or system shutdowns. Symptoms include: Water pooling around your indoor unit Musty odors Sudden AC shutoff We can clear the blockage and get your system draining properly to prevent future issues. 3. Dirty Air Filters It may seem simple, but dirty or clogged filters are behind many of the service calls we handle in the summer. Poor airflow puts extra strain on your system, reduces cooling performance, and can even cause your evaporator coil to freeze. What to look for: Weak airflow Uneven cooling in rooms Higher energy bills Tip: Check and replace your air filter every 1–2 months—especially during the summer. 4. Electrical Component Failures Summer heat can stress key components like capacitors and contactors, causing them to overheat or fail. When this happens, your AC may not start or may shut off unexpectedly. Common signs: Clicking or buzzing noises AC won’t turn on Short cycling (frequent starting and stopping) We carry replacement parts on our trucks and can usually fix these issues quickly. 5. Frozen Evaporator Coils Yes, it sounds odd in the middle of summer—but frozen coils are more common than you think. Poor airflow or low refrigerant can cause the coil to freeze, stopping your system from cooling your home. Watch for: Ice buildup on the indoor unit Reduced airflow AC runs but doesn’t cool the home We’ll diagnose the cause, safely defrost your unit, and make any necessary repairs.

Why Is My AC Blowing Warm Air? Common Summer HVAC Issues in Lexington, SC

June 30, 2025
When summer hits Lexington, SC, the heat and humidity can be relentless—and the last thing you want is your air conditioner blowing warm air. At Brian’s Heating & Cooling, we hear this complaint all too often during peak summer months. If your AC isn’t keeping your home cool and comfortable, there could be several common issues at play. Let’s break down the most frequent reasons your AC might be blowing warm air—and what you can do about it. 1. Your Thermostat Is Set Incorrectly It may sound obvious, but we always start here. If your thermostat is accidentally set to “heat” instead of “cool”, your AC will blow warm air. Double-check the settings, and make sure the fan is set to “auto” instead of “on” (which can circulate warm air when the system isn’t actively cooling). 2. Refrigerant Levels Are Low or Leaking Refrigerant is the substance your AC uses to absorb heat and cool your home. If your system is low on refrigerant—or if there’s a leak—your AC won’t be able to cool properly. This is not a DIY fix. Call a licensed HVAC technician in Lexington to inspect and recharge the system if needed. Pro Tip: Refrigerant issues often come with other symptoms like hissing noises, ice buildup on the coils, or reduced airflow. 3. Dirty or Clogged Air Filters A dirty air filter restricts airflow, causing your system to work harder and potentially overheat. When this happens, the system may blow warm or room-temperature air. We recommend replacing your air filter every 1–3 months, especially during the summer when your AC runs constantly in Lexington’s high humidity. 4. Electrical Issues or Blown Fuses Sometimes, the indoor unit is working, but the outdoor condenser isn’t. This can happen due to a tripped breaker or a blown fuse. If the outdoor unit isn’t running, the system can't complete the cooling cycle—leaving you with warm air. A quick inspection of your circuit breaker panel may reveal the problem. If a fuse has blown or a breaker continues to trip, it's time to call an HVAC professional. 5. Frozen Evaporator Coils Ironically, frozen coils can cause warm air. When the evaporator coil freezes, it can’t absorb heat properly, which interrupts the cooling process. This can be caused by low refrigerant, dirty filters, or blocked airflow. If you notice ice forming on your AC unit, shut it off and contact our Lexington HVAC team right away. 6. A Faulty Compressor The compressor is the heart of your AC system, pumping refrigerant between the indoor and outdoor units. If the compressor fails, your system can’t cool at all. This is a serious issue that usually requires professional repair or replacement. 7. Poor Maintenance or Lack of Seasonal Tune-Ups Regular HVAC maintenance is essential in Lexington, SC, where AC systems are under constant stress during hot summers. Neglected systems are more prone to breakdowns, warm airflow, and costly repairs. At Brian’s Heating & Cooling, we offer affordable maintenance plans to keep your system running at peak performance year-round. Check out our maintenance service page to learn more!

Is Your AC Ready for the Lexington Summer? Here’s a Quick Checklist

May 29, 2025
Summer in Lexington, SC can be brutally hot and humid — and the last thing you want is for your air conditioner to fail just when you need it most. At Brian’s Heating & Cooling, we want to help you stay cool and comfortable all summer long. Here’s a quick checklist to make sure your AC is ready for the South Carolina heat. ✅ 1. Check and Replace Your Air Filter One of the easiest — and most important — things you can do is replace your HVAC filter regularly. A dirty filter restricts airflow, reduces efficiency, and can put unnecessary strain on your system. We recommend checking your filter every month and replacing it at least every 60–90 days. ✅ 2. Inspect Your Thermostat Make sure your thermostat is working properly and set to “cool.” If you’re still using an older manual thermostat, consider upgrading to a programmable or smart thermostat to save energy and improve comfort. ✅ 3. Clear Debris Around the Outdoor Unit Your outdoor AC unit needs room to breathe. Clear away leaves, grass clippings, and any other debris within a two-foot radius. Trim back any bushes or shrubs that may be too close to the unit. ✅ 4. Check Air Vents and Registers Walk through your home and make sure all vents are open and unobstructed. Blocked vents can lead to uneven cooling and increased energy bills. ✅ 5. Listen for Strange Noises If your AC is making unusual sounds like banging, grinding, or squealing, that could be a sign something is wrong. Don’t wait — schedule a service call with our team before a small issue turns into a major repair. ✅ 6. Test the System Before Peak Heat Turn your system on before the hottest days arrive to make sure it’s cooling properly. If you notice weak airflow, warm air, or the system isn’t turning on at all, give us a call right away. ✅ 7. Schedule a Professional AC Tune-Up An annual maintenance check from Brian’s Heating & Cooling can extend the life of your system, improve efficiency, and catch small problems before they become big headaches.
