Furnace and heat pump repair in Lebanon, TN
Gas, propane or heat pump, we repair it, day or night, from our home office on Chicken Road.
Lebanon homes heat in more ways than most cities. Some have natural gas furnaces. Many outside the city have propane. A lot of newer houses use heat pumps, and some use a dual-fuel combination. Each fails in its own way, and a repair company that treats them all alike will miss things.
Heavenly Air repairs furnaces, propane heating equipment and heat pumps in Lebanon and across Wilson County, with technicians available 24 hours a day. We work on all makes and models, and we start every call by finding out exactly what you have.
Propane and rural heating calls
Past the edge of town, natural gas is not always available, so propane furnaces and electric heat pumps are common. Propane equipment needs the same care as natural gas, plus attention to the supply side. If a propane furnace will not light, we check the tank level and regulator as well as the ignitor, flame sensor and gas valve, and we make sure the vent is clear. A rural address also changes how we plan the call, which is one reason local matters.
Why furnaces fail on the first cold night
Most Lebanon heating emergencies happen in the same two or three weeks each year. After months of sitting idle, a weak part finally gives out when asked to run all night: a dirty flame sensor that shuts the burners down, a cracked ignitor, a failing inducer or blower motor, or a clogged filter that causes the furnace to overheat and shut itself off. Many of those problems would have been caught by a fall tune-up. See HVAC maintenance in Lebanon.
What we check on a furnace repair
A thorough diagnosis covers more than the part that failed:
- Thermostat, wiring, power supply and safety switches
- Ignition system, flame sensor, burners and gas valve
- Blower motor, capacitor and electrical connections
- Heat exchanger, flue and combustion for safe operation
- Airflow and temperature rise, to confirm the furnace is delivering what it should
- On heat pumps, the defrost cycle, reversing valve, refrigerant charge and auxiliary heat
Carbon monoxide and gas safety
Never ignore a gas smell or a carbon monoxide alarm. If you smell gas, leave the house at once and call your gas utility or propane supplier and 911 from outside. We recommend working carbon monoxide detectors on every level of any home with fuel-burning equipment, an attached garage or a fireplace. If we find a cracked heat exchanger or a blocked flue, we will explain what has to happen before the system is safe to run.
When we recommend replacing instead of repairing
A furnace past 15 to 20 years old, a cracked heat exchanger, or a heat pump that needs a major component are good reasons to ask for a replacement estimate. It is free, and we will explain gas, propane, heat pump and dual-fuel options. See heating installation in Lebanon.
Furnace & Heat Pump Repair in Lebanon: common questions
Do you repair propane furnaces?
Yes. We repair propane and natural gas furnaces as well as heat pumps and dual-fuel systems, all makes and models.
My furnace is blowing cold air. What should I check?
Confirm the thermostat is on heat and not fan only, replace a dirty filter, and check the breaker and service switch. If it still blows cold, the flame sensor, ignitor or a safety switch may be shutting the burners down. Call us.
Is it safe to run my furnace if it smells odd?
A brief dusty smell the first time you run it each fall is normal. A smell that lingers, a gas smell or a metallic odor is not. Shut it off and call.
Do you offer 24/7 heating repair in Lebanon?
Yes. Our technicians are available 24 hours a day, every day of the year.
