Heating & Furnace Repair the way our technicians do it
Most Middle Tennessee no-heat calls in the first genuinely cold week are the same handful of things: a dirty flame sensor, a failed ignitor, or a heat pump that has never had its auxiliary heat checked because it has not been needed. They are inexpensive repairs when caught, and expensive when a system runs on strip heat all winter unnoticed.
A cracked heat exchanger is the one furnace fault that is not a comfort question. If we find one we will show you and we will red-tag the unit, because the alternative is combustion gases in the return air. That is not a repair we negotiate on.

Furnace Not Turning On, or Lighting and Then Quitting
Some furnaces that will not run need a breaker or a filter. Others are shutting themselves down on purpose, and those are the ones you should never reset twice.

Told Your Furnace Has a Cracked Heat Exchanger
Few words from a technician end a furnace faster than cracked heat exchanger. The diagnosis is sometimes right, sometimes wrong, and always worth seeing for yourself.

Why Your Air Conditioner or Furnace Short Cycles
Short cycling wears equipment out faster than running it hard, and it never gets the humidity out of a Nashville house. Here is how to tell which cause you have.

FAQ
Questions owners ask about heating & furnace repair
Why is my heat pump blowing cold air in winter?
Often it is working normally: heat pumps deliver air that feels cool compared with a furnace because it is only a little above room temperature, and they run defrost cycles that briefly reverse. Genuine faults are a failed reversing valve, low refrigerant, or a system that has switched to expensive auxiliary heat because it cannot keep up. If the house is not reaching temperature, that is the fault to chase.
What is a cracked heat exchanger and why does it matter?
The heat exchanger is the metal wall between the combustion gases and the air blown into your house, and a crack lets those gases — including carbon monoxide — into the airstream. It is the one furnace fault that is not repaired; the furnace is replaced. A carbon monoxide detector on each level of the house is the cheapest insurance against it.
