Charleston, SC HVAC Service & Installation

As fall settles into the Lowcountry, mornings are cooler, evenings are crisp, and the air conditioning finally gets a well-earned break. But before you flip your system to “heat” and forget about it, it’s worth taking a few simple steps to make sure your heat pump is running at peak efficiency for the months ahead. Here in Charleston, we rely on our heat pumps year-round — for both cooling and heating — and that means a little seasonal attention goes a long way toward lower bills and better comfort. Switch Modes Smoothly Your heat pump works differently than a traditional furnace. When it transitions from cooling to heating, it’s normal to hear a few new sounds or feel slightly cooler air from the vents at first. However, if your system struggles to reach temperature or runs constantly, that’s a sign it could use a tune-up. Before the first truly chilly week arrives, switch your thermostat to “heat” and let the system run for 10–15 minutes to make sure everything transitions smoothly. Adjust Your Thermostat Settings for the Season Fall is a perfect time to rethink thermostat habits: Set a comfortable base temperature — around 68°F when you’re home and awake. Use a programmable or smart thermostat to automatically adjust when you’re asleep or away. Avoid setting the temperature too high too fast; gradual changes prevent your system from switching into less-efficient “auxiliary heat” mode. These small adjustments can reduce energy use significantly without sacrificing comfort. Clear Around Your Outdoor Unit Falling leaves, pine needles, and yard debris can collect around your outdoor unit, restricting airflow. Take a few minutes to: Trim back vegetation within two feet of the unit Gently rinse away dirt or debris with a garden hose Check for signs of damage or corrosion after hurricane season Good airflow helps your system exchange heat efficiently — a key factor in keeping energy costs low. Check Insulation and Weatherstripping Even in our mild Charleston winters, poor insulation can make your system work harder than it should. Inspect: Weatherstripping around doors and windows Attic insulation, especially above living spaces Drafts near baseboards or crawlspaces A few quick fixes (like new door seals or outlet gaskets) can keep warm air inside — and your heat pump from cycling on and off too often. Schedule a Fall Maintenance Check Your heat pump works double duty all year long, so professional maintenance twice a year is best. A fall tune-up ensures: Heating coils and defrost cycles are working properly Refrigerant levels are balanced Electrical connections are tight Backup heat strips (if you have them) are tested before you need them A well-maintained system can save you up to 25% on energy costs — and avoid the stress of a cold-morning breakdown. Charleston’s fall and winter may not bring snow, but our heat pumps still earn their keep. A little preparation now can mean steady comfort and lower utility bills all season long.
