Understanding Common HVAC Problems and Solutions
February 13, 2024
As the trusted HVAC contractor serving Lexington, SC, we understand that a malfunctioning heating, ventilation, and air conditioning (HVAC) system can disrupt your comfort and peace of mind. From sudden breakdowns to inefficient operation, various issues can arise with your HVAC system. Fortunately, many common problems have straightforward solutions when addressed promptly by knowledgeable professionals. Here, the Brian's Heating & Cooling team will explore some of the most frequent HVAC problems and their solutions:
- Poor Airflow: If you notice weak airflow from your vents, it could indicate issues such as clogged air filters, blocked vents, or ductwork leaks. Solution: Change or clean air filters regularly, ensure vents are unobstructed, and have ductwork inspected and sealed as needed.
- Uneven Heating or Cooling: Uneven temperatures throughout your home can result from issues with ductwork, thermostat calibration, or system sizing. Solution: Have ductwork inspected for leaks or blockages, recalibrate your thermostat, and consider upgrading to a properly sized HVAC system if necessary.
- Noisy Operation: Loud or unusual noises from your HVAC system, such as banging, rattling, or squealing, could indicate mechanical issues or loose components. Solution: Schedule a professional inspection to diagnose and repair any mechanical problems, such as worn-out parts or loose connections.
- Frequent Cycling: If your HVAC system turns on and off frequently, it could be due to issues with the thermostat, airflow restrictions, or refrigerant leaks. Solution: Check thermostat settings and recalibrate if necessary, ensure adequate airflow by cleaning vents and ducts, and schedule a professional inspection for refrigerant leaks and system repairs.
- High Energy Bills: A sudden increase in energy bills without a corresponding change in usage could signal inefficient operation or energy loss. Solution: Schedule routine HVAC maintenance to ensure system efficiency, seal air leaks in ductwork and around windows and doors, and consider upgrading to a more energy-efficient HVAC system.

As we settle into late January in Lexington, South Carolina, residents are seeing classic winter weather — chilly days with highs often in the 40s and 50s, cold nights in the 20s, and even the potential for accumulating snow and hazardous conditions this weekend. A Winter Storm Warning has been issued for the area with forecasts showing several inches of snow and strong winds that could make travel difficult and impact home comfort systems. This kind of weather — especially when snow and ice are on the way — puts unique demands on your home’s heating and HVAC systems. With Brian’s Heating & Cooling in Lexington, SC, it’s a great time to think beyond “just turning on the heat” and focus on comfort, safety, and efficiency. Winter Weather + HVAC: Why It Matters Now Unlike the more routine cool spells earlier in winter, this cold stretch — with freezing temps and snow chances — highlights a few key HVAC considerations: 1. Keep Warmth In, Costs Down Cold air easily slips into poorly sealed homes. Before a cold snap hits, check for drafts around doors, windows, and attic entries. Sealing leaks can keep your heating system from working overtime and lower energy bills. 2. Protect Your System Under Load When temperatures drop and snow accumulates, your furnace or heat pump works harder than usual. A well-maintained system not only heats more consistently but also reduces the risk of breakdowns when you need it most. 3. Clear Outdoor Units Carefully If you use a heat pump, snow and ice can build up around the outdoor unit. Gently clear snow away (don’t use sharp tools!) so airflow isn’t obstructed — essential for efficient operation in cold weather. 4. Watch for Ice on Pipes Frigid nights below freezing can threaten pipes, especially in unfinished spaces like garages and crawlspaces. Keep garage doors closed and consider insulating exposed pipes to prevent costly bursts. HVAC Comfort Tips for Winter Storm Conditions Here are a few practical ways to maintain comfort during cold spells like this: Change filters regularly: A clean filter ensures good airflow, reducing strain on your heating system. Use your thermostat smartly: Setting it a few degrees lower at night can save energy, but avoid drastic swings which make your system work harder. Schedule a winter checkup: A professional inspection can catch issues before they turn into emergency repairs during a storm.

The holidays are here in Lexington — and that means cozy gatherings, delicious meals, and (often) a full house! While your HVAC system has likely already transitioned to heating mode, this time of year comes with its own challenges: fluctuating indoor temperatures, extra foot traffic, and the heavy use of kitchens and ovens that can throw off your home’s comfort balance. At Brian’s Heating & Cooling , we want you to enjoy a comfortable home without draining energy or stressing your system. Here’s how to make the most of your heating system this holiday season — whether you’re hosting a big family dinner or just trying to stay cozy all winter long. 1. Balance Comfort With Efficiency When guests arrive, everyone has their own comfort preference — which can lead to thermostat wars! Instead of constantly adjusting the thermostat, try this: Set your thermostat at a comfortable base temperature (around 68–70°F is usually ideal for winter in South Carolina). Use zoned heating and programmable thermostats to keep main gathering areas comfortable while reducing output in unused rooms. If you have a smart thermostat , program temporary schedules for anticipated guest times. This helps reduce energy waste while keeping your home cozy when it matters most. 2. Understand How Kitchen Use Affects Heating Holiday meals mean ovens running for hours — and that extra heat can actually confuse your thermostat. When the oven is on: Warm air from the kitchen can signal your thermostat that the whole house is warm, causing the heat to kick off prematurely. To prevent this, make sure the thermostat isn’t placed directly near the kitchen or stove area. If you notice the heat cycling off and on more than usual, consider placing a small fan or moving the thermostat’s signal path slightly to avoid false readings. 3. Close Off Unused Spaces With guests spread across rooms, it’s easy to overlook bedrooms or spaces no one uses during a gathering. Closing vents and doors in those areas can: Improve airflow where it’s needed most Reduce heating zones that no one is using Lower your overall energy usage Just be sure not to close more than 20–30% of your vents — too many closed vents can create pressure imbalances and restrict airflow. 4. Keep Airflow Clear Holiday décor and extra seating can sometimes block vents or registers. Before company arrives: Make sure all vents are visible and unobstructed Keep furniture and holiday decorations at least a few inches away from vents Let warm air circulate freely to avoid cold spots This helps your HVAC system heat evenly and efficiently throughout your home. 5. When to Call Brian’s Heating & Cooling If your heating system struggles to keep up during gatherings — or if you notice odd noises, uneven temperatures, or higher-than-usual energy costs — it may be time for professional help.

With November upon us, the weather in Lexington is shifting — daytime highs are cooling off, nighttime temps are dropping, and the heat will soon be running much more often. At Brian’s Heating & Cooling, we want to help you stay cozy and protected from unexpected HVAC issues as winter approaches. Here are our top recommendations to prepare your home for the season ahead: 1. Replace or Clean Your Air Filters As your heating system kicks into gear, a clean filter is more important than ever. A dirty or clogged filter restricts airflow, reduces comfort, and forces your HVAC system to work harder than it should. Change your air filter now to improve both efficiency and indoor air quality. 2. Clear Debris Around Outdoor Units Even though cooling season is behind us, your outdoor equipment still needs attention. Clear away leaves, pine straw, and other yard debris so the system can breathe properly and avoid airflow blockages. 3. Test Your Heating System & Thermostat Don’t wait for the first freezing night to find out there’s a problem. Switch your system to heat mode and run a quick test cycle. Make sure each room warms evenly and check that your thermostat responds correctly. If you have a programmable or smart thermostat, update the settings for your winter schedule to help conserve energy. 4. Inspect Vents, Ducts & Return Air Paths Warm air needs a clear path to keep your whole home comfortable. Ensure furniture and rugs aren’t blocking vents, and consider having your ducts inspected if you’ve noticed uneven heating or excess dust in the air. 5. Schedule a Professional HVAC Tune-Up Even with great DIY maintenance habits, your system benefits from a professional inspection. A trained technician will perform a full safety and efficiency check, clean internal components, and identify early warning signs before they turn into costly repairs. A simple tune-up now can prevent unexpected breakdowns during the coldest days of winter.
