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.

Time to Replace?
Is Your Furnace Due for Replacement?
Holding on to an aging furnace costs more in repairs and energy bills than investing in a new system. Here's how to know when it's time:
- Furnace is 18–25 years old — most gas furnaces last 15–20 years
- Repair costs exceed 50% of new system cost
- Heat exchanger is cracked — a serious safety issue that requires replacement
- Rising gas bills despite consistent usage
- Uneven heating and persistent cold spots in your home
- System needs repairs more than once per heating season
- You want lower monthly utility bills and quieter operation

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!
