  • Straightforward Options - Transparent pricing for repair paths, plus warranty coverage.

  • On-the-Spot Repair - Common parts are on the truck: igniters, sensors, capacitors, blower/inducer motors, relays, control boards. That means same day repairs unless a specialty part needs to be ordered.

Common Furnace Repair Questions

Do you offer same-day service?
Yes. Morning calls have the best chance at same-day diagnostics and repair.

How much does a typical repair cost?
It depends on the part and labor (e.g., igniter vs. inducer motor). We use flat-rate pricing, so you'll know the total before work begins.

What brands do you service?
We work on all major brands and models, including gas furnaces, heat pumps, and dual-fuel systems. A few examples: Trane, American Standard, Carrier, Lennox, Daikin, Goodman, Amana, Rheem and more!

Will you try to sell me a new system?
No. If a repair is the smart move, we'll recommend it. If replacement makes more sense, we'll show clear numbers and let you decide.

Do you provide warranties on repairs?
Yes—written parts & labor warranty on the work we perform. Your tech will outline terms before you approve.

Are your technicians licensed and insured?
Yes. Guardian is fully licensed & insured; our techs are factory-trained and background-checked.

Is my family safe during and after the repair?
Safety comes first. We perform appropriate heater checks verifying venting, and inspect heat exchangers where applicable.

Do you offer financing?
Yes—financing options are available for larger repairs or full system upgrades. Ask your expert or scheduler for details.

Guardian performs heater and furnace repairs with daily routes through Woodstock, Kennesaw, Acworth, Marietta, Alpharetta, and Cartersville—plus surrounding North Metro Atlanta neighborhoods.
