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.

Warning Signs
Signs Your Heating System Needs Attention
Don't wait for a breakdown to schedule service. These signs indicate your heating system is overdue for a professional tune-up:
- Longer warm-up times — system takes much longer to reach set temperature
- Uneven heating — some rooms warm, others cold
- Unusual smells — dusty, musty, or burning odors when heat kicks on
- Strange noises — rattling, banging, or whistling from the unit
- Rising energy bills — declining efficiency driving up monthly costs
- Yellow pilot light (gas furnaces) — should always be blue; yellow signals combustion issues

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!
