Most heating calls in our area come in three waves: the first cold front in November, the Christmas-week freeze, and whatever the February surprise is. Because so many homes here run heat pumps (which struggle below 35°F without an electric backup or auxiliary strip), diagnosing heating issues correctly matters — we don't just replace parts and hope.
Heating issues we see every winter
Furnace blowing cold air
Failed ignitor, flame sensor, gas valve, or thermocouple. These are safety components — never DIY, never ignore.
Heat pump stuck in cool or won't switch over
Bad reversing valve or control board. Common in our area because heat pumps cycle modes constantly.
Strange smells when heat first kicks on
Dust burn-off is normal for a minute — anything longer could be a motor issue or a cracked heat exchanger (carbon monoxide risk).
Furnace short-cycles on/off
Oversized system, dirty filter, bad flame sensor, or a failing pressure switch. Each one has a different fix.
Auxiliary 'emergency heat' runs constantly
Heat pump isn't transferring heat — usually a low refrigerant charge, failing outdoor fan, or frozen coil.
Cold spots in parts of the house
Often a zoning or duct-balance issue — not always a heat source problem. We investigate before we quote.
Our process — four steps, zero surprises
- Book in two minutes. Online or by phone. Confirmation within the hour.
- Text when we're rolling. Tech photo, live ETA, and a real window — not a 4-hour guess.
- Diagnose and quote flat. We walk you through what we found, show you the part, and quote in writing. Nothing starts without a yes.
- Fix it and back it up. Most repairs done in one visit. Every job carries a workmanship guarantee.
How much does heating repair cost in Baton Rouge?
