Common Furnace Problems We Fix

These are the furnace issues we see most often in St. Louis homes. Most can be repaired in a single visit.

Furnace Not Producing Heat

If your furnace runs but blows cold air, the issue could be a failed heat exchanger, a bad ignitor, or a limit switch tripping due to overheating. We diagnose it correctly the first time.

Furnace Won't Turn On

Failed control boards, bad pressure switches, and faulty igniters are common causes. We test components systematically to find the problem without guessing.

Short Cycling (Turns On and Off Rapidly)

Short cycling usually means the furnace is overheating and shutting down as a safety measure. Causes include clogged filters, blocked vents, or a cracked heat exchanger.

Pilot Light or Ignition Problems

Modern furnaces use electronic ignition — when it fails, your furnace won't light. We inspect and replace igniters, flame sensors, and gas valves.

Blower Running Constantly

If the fan runs nonstop, the issue is usually a stuck relay or faulty thermostat. We trace the electrical circuit and fix the cause.

Loud Banging, Rattling, or Squealing

Banging on startup can mean delayed ignition or dirty burners. Squealing often means a worn blower motor bearing. We find the noise source and fix it before it becomes a bigger problem.

Furnace Repair FAQ

How much does furnace repair cost in St. Louis?

Our service call and diagnostic fee is $125. The repair cost depends on the issue — replacing a capacitor or igniter is less expensive than repairing a heat exchanger or control board. We quote the full cost before starting any work.

How quickly can you get someone out to fix my furnace?

For emergencies (no heat in winter), we target a 1-hour response time. For non-emergency repairs, we typically schedule within 1-2 business days. Call (636) 778-0378 for the fastest response.

My furnace is old — should I repair it or replace it?

If the furnace is under 10 years old, repair almost always makes sense. If it's 15+ years old and needs a major part, replacement may be more cost-effective. We'll run the numbers honestly and let you decide — no pressure either way.

Do you work on all furnace brands?

Yes. While we specialize in Bryant systems for new installs, our technicians are trained to diagnose and repair all major furnace brands including Carrier, Trane, Lennox, Rheem, and others.
