Heating Repair in Locust Grove, GA

When the board fails and the metal is fine

Newer houses come with newer heat pumps, and the thing that catches people out is not age — it is electronics. A modern system is controls as much as it is metal. A defrost board, a sensor, or a thermostat that has lost the plot will leave you cold on a January morning while every single mechanical part in that system is in perfect health.

Which is worth knowing before somebody quotes you a compressor for it. We diagnose the controls and the mechanicals as one system, because that is what they are, and we tell you which end the fault is actually at. On a unit that is only a few years old, that distinction is usually the difference between a part and four figures.

It is also worth knowing that a heat pump running a defrost cycle looks alarming and is completely normal. Steam rolling off the outdoor unit, a loud whoosh, the fan stopping dead, cool air from the vents for a minute or two — that is the system deliberately melting frost off its own coil in the middle of winter. It is the unit working, not failing. A fair number of perfectly healthy heat pumps have been replaced by people who were told otherwise.

The calls we get all winter

• The heat pump is blowing cool air on a cold morning
• Emergency heat is stuck on and the power bill is climbing
• The furnace runs but nothing warm comes out
• The burner won’t light, or lights and drops straight out
• A bang or a rattle every time it starts
• One room roasts and the next one freezes
