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.

Why Sub Zero
Why Indoor Air Quality Matters
Allergy & Asthma Relief
HEPA filtration and UV purifiers remove the pollutants that trigger allergic reactions and asthma attacks.
Germ & Virus Reduction
UV light systems neutralize bacteria, mold spores, and viruses circulating through your HVAC system.

Proper indoor humidity (30–50%) reduces respiratory discomfort and prevents mold growth year-round.
Fresh Air Ventilation
ERV systems bring in fresh outdoor air while recovering conditioned air energy — healthier and efficient.

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!
