About Sub-Zero
Founded in Madison, Wisconsin, Sub-Zero pioneered the dual-compressor refrigeration system that separates freezer and refrigerator environments. This innovation prevents flavor transfer and maintains optimal humidity — especially valuable at Boulder's naturally low humidity levels. Today, Sub-Zero products anchor the kitchens of homes along Flagstaff Road, in the neighborhoods around Chautauqua, and throughout Boulder County.

Common Questions
Sub-Zero Repair FAQ
How often should my Sub-Zero condenser coils be cleaned in Boulder?
Every 6 months minimum — more often during cottonwood season (June-July). Boulder's dry, dusty conditions and abundant cottonwood trees clog condenser coils faster than most climates, forcing the compressor to work harder and shortening its lifespan.
Why is my Sub-Zero refrigerator not as cold as it should be?
At 5,430 feet, several altitude-specific factors can reduce cooling: incorrect refrigerant charge for elevation, dirty condensers (common in Boulder), failing door gaskets dried by low humidity, or thermostat drift. We check all these variables on every service call.
Do you carry Sub-Zero replacement parts?
We stock common Sub-Zero parts including water filters, gaskets, fan motors, and thermostats. For less common components, we source OEM parts directly and typically have them within 24-48 hours.
What Our Neighbors Say
Sub-Zero Repair Reviews
Based on reviews from Boulder County homeowners
Wine collection was at risk when our Liebherr wine cabinet lost temperature control in one zone. Same-day response, diagnosed a failing zone thermostat, ordered the part and returned next day. Our collection is safe. Can't recommend enough.
Emergency call at 7 PM when our Sub-Zero 648PRO alarm went off. Technician talked us through immediate steps on the phone, then arrived first thing next morning. Saved everything in the fridge. Above and beyond service.
Our Thermador Freedom induction cooktop had two dead zones. The technician diagnosed a failed power board in the right cluster and replaced it with a genuine OEM part. Back to full cooking power. Fair pricing, no surprises.
