- Furnace short cycling — Turning on and off rapidly — usually overheating, dirty filter, or faulty limit switch
- Loud or unusual noises — Banging, rumbling, squealing, or whistling all signal different problems

Should You Repair or Replace Your Furnace?
A simple rule: if your furnace is over 15 years old AND the repair costs more than 50% of a new system, replacement is usually smarter. Our technicians will give you an honest recommendation based on:
- Age of the furnace
- Cost of the repair
- Energy efficiency rating (AFUE %)
- Frequency of past repairs
- Heat exchanger condition (cracked = replace, period — safety issue)
If replacement makes more sense, ask us about Furnace Replacement and our financing options — including 0% interest plans on qualifying systems.

Frequently Asked Questions — Furnace Repair
How quickly can you come fix my furnace? We offer same-day service for most furnace repairs in Cumming, Alpharetta, Roswell, Milton, and Johns Creek. No-heat emergencies get priority.
Is it safe to use my furnace if it's not working right? No. Strange smells, soot, yellow flames, or a CO detector going off are serious safety issues. Turn off the furnace at the thermostat and breaker, then call us immediately. If you smell gas, leave the home and call 911 first.
How much does furnace repair cost in Cumming GA? Most furnace repairs range from $150 to $750 depending on the issue. We provide upfront written quotes before any work begins.
Do you repair all furnace brands? Yes. We service every major brand — Bryant, Carrier, Lennox, Trane, Rheem, Goodman, Amana, York, Daikin, American Standard, and more.
Is my furnace repair covered under warranty? If your furnace is still under manufacturer warranty, we'll handle the warranty paperwork for you. Ask when you call.
What if I need a part you don't have? We carry the most common furnace parts on every truck (ignitors, flame sensors, capacitors). For specialty parts, we typically have them within 24-48 hours.
Do you offer financing for major repairs? Yes — 0% interest financing available on qualifying repairs and replacements. Learn more.
How long does a furnace repair take? Most common repairs (ignitor, flame sensor, capacitor) take 30-90 minutes. More complex repairs (gas valve, blower motor) may take 2-4 hours.
My furnace is making a banging sound — is it dangerous? A banging sound at startup can mean delayed ignition — gas building up before lighting. This is dangerous and can damage the heat exchanger. Turn off the furnace and call us immediately.
Should I be worried about a cracked heat exchanger? Yes — this is a serious safety issue. A cracked heat exchanger can leak carbon monoxide into your home. We never recommend repairing a cracked heat exchanger — replacement is the only safe option.
