Homeowners' pick for heating and cooling across Tennessee
Heat Pump Repair in Maryville, TN — Book a Visit Today
When a heat pump runs constantly and the house still will not warm up, the trouble is often a stuck reversing valve, a failed defrost board or a low charge. Ice covering the outdoor coil for hours instead of clearing on its own is another sign. We do heat pump repair for Maryville homes on straight electric systems and on dual-fuel pairings with a gas or propane furnace, which are common around here given mild winters broken by hard freezes. Clear snow and leaves from around the outdoor cabinet, then call us or fill out the quote form.

Why is my heat pump blowing cool air in winter?
Heat pump air is cooler than furnace air by nature, so lukewarm can be normal. Genuinely cool air usually means a stuck reversing valve, low refrigerant, or the outdoor unit is not running and the indoor backup heat is carrying the house alone.
Is ice on the outdoor unit always a problem?
A light frost that clears during a defrost cycle is normal. Thick ice covering the coil, or ice that never melts, points to a defrost sensor or board failure, an airflow restriction or a charge issue. Call us before running it further.
What is a dual-fuel system and why does mine switch back and forth?
Dual-fuel pairs a heat pump with a gas or propane furnace. A control decides which one runs based on outdoor temperature. Switching is normal, but if the furnace runs on mild days the changeover setting, outdoor sensor or thermostat wiring needs checking.
Can you repair my heat pump in cold weather?
Yes. Heating season is when most heat pump calls come in. We diagnose in the cold every winter, and we will tell you plainly whether a repair holds or whether the unit is at the end of a reasonable life.
How soon can you get to my house in Maryville?
Call us and we will tell you honestly what the schedule looks like that day. Summer heat and the first hard cold snap are our heaviest weeks, so no-cooling and no-heat calls in Maryville get priority over routine work. If you are waiting, check that the thermostat is set to cool and has fresh batteries, look for a tripped breaker, and clear leaves and grass clippings away from the outdoor unit.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form and describe what changed. Warm air, no air, a smell, a noise, a breaker that keeps tripping. That detail tells us what parts to bring along.
- Step 2
We diagnose on site
We check the thermostat, the electrical side, airflow and the equipment itself before we quote anything. If the problem sits in the ductwork rather than the unit, we say so plainly.
- Step 3
We repair and explain
Most air conditioning repair and heating repair work finishes in one visit. We show you the failed part, explain what caused it, and tell you what to watch for next season.

Why homeowners call us
- Propane and dual fuelPlenty of homes in our service area run propane heat or a dual fuel setup with a heat pump. We know how those systems switch over and why a bad changeover setting can leave you cold and burning fuel.
- Older houses, added ductworkFarmhouses often got ducts decades after they were built, run through crawl spaces and attics. When the equipment tests fine but rooms still fight each other, we look at the duct runs and static pressure.
- Repair before replacementA failed capacitor, a cracked wire, a clogged drain or a bad control board is a repair, not a new system. We tell you when the equipment is genuinely finished and when it is not.
- Plain talk on the phoneWe ask what the thermostat reads, whether the outdoor unit is spinning, and when it last worked normally. That two minute conversation often shortens the visit and keeps the repair cost down.
