I highly recommend this honest business! Our hallway control panel went completely dark, and the repairman quickly found a loose wire behind the drywall, restoring our heat in minutes.

Know the Signs
Furnace Problem Warning Signs
Your furnace usually gives warning signs before a complete failure. Don't ignore them:
- Furnace runs but doesn't produce heat
- Short cycling — turns on and off every few minutes
- Yellow, orange, or flickering pilot light (should be blue)
- Gas smell near the furnace — call immediately, this is an emergency
- Unusual banging, rattling, squealing, or grinding noises
- Carbon monoxide detector activating near the furnace
- Increasing gas bills despite similar usage
- Cold spots throughout the house
How it works
Our Furnace Repair Approach

- 02
Safety Inspection First
Before diagnosing the fault, we check for gas leaks, CO risks, and heat exchanger cracks — your family's safety comes first.
- 03
Pinpoint Diagnosis
We use diagnostic tools and manufacturer service procedures to identify the exact failed component.
- 04
Quality Repair & Test
We repair using quality parts, then test combustion, safety controls, and heat output before declaring the job complete.

What neighbors say
Neighbors, in their words.
My central air completely froze over with ice during a humid weekend, but the tech from Sub Zero came out fast to thaw and fix the refrigerant leak. Everything is running perfectly now, and the house is finally comfortable again!

Our air stopped working completely and we panicked. The repair guy came over quickly and figured out the wall thermostat just needed new batteries. He swapped them out, checked the rest of the system to be safe, and didn't overcharge us. Very honest and simple service. Highly recommend!
