How our diagnostic service works
A good repair starts with an accurate diagnosis. We do not guess and we do not throw parts at a problem. We test the system the way it was designed to run: we check voltage and amperage, refrigerant pressures, airflow, temperatures, safety switches and control signals until we know exactly what failed and why.
Once we know what is wrong, we explain it in plain words and give you the price to fix it before we start. If the repair does not make sense for an older system, we tell you that too, so you can make the right choice.
Common problems we fix
The calls we see most often in Hamblen County are an AC that runs but blows warm air, a heat pump that freezes up, a furnace that will not light, water leaking from the indoor unit, a breaker that keeps tripping, strange noises from the outdoor unit and a thermostat that does not respond.
Behind those symptoms are usually failed capacitors, contactors, igniters, flame sensors, blower motors, clogged drain lines, refrigerant leaks, dirty coils or wiring problems. We carry many common parts on the truck so a lot of repairs are finished on the first visit.
What to check before you call
Make sure the thermostat is set to heat or cool and the batteries are good. Check that the breaker for the indoor and outdoor unit has not tripped. Look at your air filter; a filter clogged with dust can stop a system cold. If the indoor unit has a float switch and water in the pan, the drain may be clogged. If none of that fixes it, give us a call at 423-312-9859.
Repair or replace?
If a repair is small compared to the value of the system, we fix it. If your equipment is old, has needed several major repairs, or the repair costs a large share of a new system, we show you both options side by side so you can make the call that makes sense for your budget.
Residential and commercial repair
We repair split systems, heat pumps, gas furnaces, mini splits and packaged rooftop units for homes, rental properties, offices, shops and restaurants. Businesses can count on us to communicate clearly about downtime and get equipment back running.
Frequently asked questions
- Is there a charge to diagnose my system?
- Yes, there is a service call fee for diagnostic work. We will tell you the fee when you book so there are no surprises.
- Can you fix it on the first visit?
- Many repairs are finished the same visit because we stock common parts. Some parts have to be ordered, and we will tell you how long that takes.
- Why is my AC blowing warm air?
- The most common causes are a failed capacitor, a dirty outdoor coil, low refrigerant from a leak or a tripped breaker on the outdoor unit.
- Why is water leaking from my indoor unit?
- Usually a clogged condensate drain line or a cracked drain pan. Turn the system off and call us to prevent water damage.
