Heating Repair

Heating & furnace repair in Chattanooga, diagnosed before it's fixed.

No heat, uneven heat, or a furnace that won't stay lit — the fix depends entirely on what the system is actually doing. We measure first, then repair, so cold rooms don't turn into a guessing game.

Signs your heating system needs attention

Rooms that never warm up, a system that runs constantly without catching up, short-cycling, rising gas or electric bills, strange smells at startup, or a furnace that locks out and won't relight. Any of these is the system telling you something measurable is wrong.

Heating complaints almost always trace back to airflow, combustion, or charge — and those are exactly the things a measured diagnostic settles in one visit.

Furnace or heat pump — do you know what you have?

A lot of homeowners aren't sure whether they're heating with a gas furnace, a heat pump, or a heat pump with electric or gas backup. The distinction matters, because the failure modes and the right repair are completely different.

We identify the system, then test it on its own terms: combustion analysis on gas equipment, refrigerant and defrost behavior on heat pumps, and static pressure and airflow on both — because a duct system that's fighting the equipment will starve either one.

How we diagnose a heating problem

A combustion analyzer reads what's happening inside a gas furnace — efficiency, and the carbon monoxide and gas numbers that tell us whether it's running safely. A manometer reads static pressure, the ALNOR balometer confirms airflow, and an IR camera spots heat-exchanger and electrical issues you can't see otherwise.

On a gas system, safety isn't optional and it isn't eyeballed. A cracked heat exchanger or a bad combustion picture is something we find with instruments and document — not something we hope isn't there.

What you get

A written record of the readings, a clear explanation of the root cause, and an estimate before the repair starts. If the data says the safe and sensible move is replacement rather than another repair on aging equipment, we'll show you the numbers and let you decide.

Common questions

Heating Repair questions, answered straight.

Why won't my furnace stay lit?
Short-cycling and lockouts usually trace back to airflow, a safety sensor, or a combustion problem — and they look alike until you measure. We read static pressure and run a combustion analysis to find the actual cause before replacing parts.
Should I worry about a cracked heat exchanger?
Yes. A cracked heat exchanger can put carbon monoxide into your air, so it isn't something to eyeball. We find it with instruments and document what we see — safety isn't a guess.
Do you work on both furnaces and heat pumps?
Both. A lot of homeowners aren't sure which they have, and the right repair is completely different. We identify the system and test it on its own terms: combustion on gas equipment, refrigerant and defrost on heat pumps.
