Furnace v. Heat Pump
A furnace creates heat using fuel or electric elements. A heat pump works by moving heat in or out of your home. Furnaces excel in extreme cold, while heat pumps offer quieter, more efficient comfort for most central Virginia homes.

Why is it so hot in here
If your AC is running but not cooling, it usually means the system is struggling with airflow, refrigerant levels, or a failing component that needs proper diagnosis. KOC Air can inspect the system end to end and pinpoint the exact issue so your cooling and COMFORT are restored quickly.

Is it Time
KOC recommends having your heat pump serviced twice a year -- once in spring and once in fall. This will keep it running efficiently and reliably. Routine maintenance helps lower energy bills, reduce surprise breakdowns and extend the life of your system. A KOC technician will clean and inspect critical components, check refrigerant levels, electrical connections and make sure your system is ready for whatever central Virginia weather dishes out.

Should I close vents
Keep every vent open -- your system will thank you for it.
​
Closing vents forces your system to push against higher pressures which can lead to hotter coils, louder operation and premature wear.
​
When vents stay open , your HVAC runs the way it was engineered to: smooth airflow, balanced pressure and consistent comfort in every corner of your home. That means lower strain on your equipment, better efficiency, and longer system life.
KOC Air can come out and perform a quick, professional system assessment to make sure your homes comfort and equipment are all working the way they should.
