Your heat pump doesn't get a season off
In Lenoir City your heat pump runs almost every month of the year, heat from October through April, then cooling from May through September. That is 12 months of the compressor cycling on and off, with barely a break to rest before the next season asks something different of it.
Winter nights averaging 32°F push the system into defrost mode again and again, reversing itself to melt frost off the outdoor coil before going back to heating. Each reversal is a strain on the valve that switches it. Summer afternoons near 87°F keep the compressor working hard for months straight. And with 10 winter storms and 60 damaging wind events recorded here over the past ten years, and one in five Tennessee households losing power for a day or more in 2024, a heat pump that loses power mid-cycle doesn't always pick back up the way it should. You may notice the outdoor unit icing over, warm air blowing when it should be cool, or the system running constantly without keeping up.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cool next to your skin even when it is working right, because the air coming out is warmer than the room but still cooler than your body. If the air is truly cold, or the system never seems to catch up on those 32°F mornings, check that the thermostat is set to heat and not fan only. A stuck reversing valve or low refrigerant can also cause this, and a contractor needs to check those.
- Why is there ice on my heat pump?
- A light coat of frost in winter is normal and the unit should melt it off on its own through a defrost cycle. If ice is building up thick and staying, something is stopping that cycle, often low refrigerant, a dirty coil, or a fan that has slowed down or stopped. Do not chip the ice off yourself. Turn the system off and have a contractor find out why the defrost cycle isn't clearing it.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running but the house is not cooling down on those 87°F afternoons, the most common causes are a dirty air filter blocking airflow, a frozen coil, or refrigerant that has leaked out. Check the filter first, since that's the one thing you can rule out yourself. If it's clean and the unit is still not cooling, the system needs a contractor to check refrigerant levels and airflow through the coil.
