Heating & Furnace Repair, No Guesswork, No Cold Nights
A dead furnace doesn't wait for a convenient day. Our technicians diagnose the real problem before touching a part — flat $95 diagnostic, no upsell games.

-
Burning, musty, or gas-like odor near the unit

Thermostat calls for heat but nothing happens

Uneven heating — some rooms warm, others cold

Heating & Furnace Repair — Frequently Asked Questions
How fast can you get a technician out for a no-heat call?
No-heat calls get same-week scheduling across Clarksville, Fort Campbell, and Springfield during our Monday–Friday, 8 AM–5 PM operating hours.
I smell something strange near my furnace — is that dangerous?
Shut the system off and call us. A gas-like, burning, or musty smell can point to a real safety issue, and every diagnostic visit includes a full ignition, gas valve, and heat exchanger safety check.
Do you repair gas furnaces, electric furnaces, and heat pumps?
Yes — our technicians diagnose and repair gas furnaces, electric furnaces, and heat pumps of any make or model.
What does the $95 diagnostic actually check?
The flat $95 diagnostic fee covers a full inspection of ignition, blower operation, gas valve, heat exchanger, and thermostat wiring — everything that typically causes a no-heat call.
Is it better to repair or replace an old furnace?
If your furnace is 12–15+ years old and the repair cost is climbing, we'll walk you through the real numbers so you can decide with confidence. See our HVAC installation & replacement page for what that looks like.
