Top Signs Your Air Conditioner Needs Repair

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.
