"Most homeowners don't know what to look for. A contractor can be charming and still skip the permit. The permit protects you — not them."
The Vetting Process
16 Non-Negotiables.
Every Single Contractor.
Most directories let anyone list for a fee. We don't. Every contractor on Thermostat passes all 16 checks — and gets re-vetted annually.

Numbers Tell Half the Story.
People Tell the Rest.
"The furnace died at 6 AM on a Tuesday in January. Thermostat matched me with a tech by 8 AM. He showed up at 10:15 — exactly when he said — pulled the permit, fixed the heat exchanger, and swept the floor before leaving. I cried a little."
Maria Okonkwo
Homeowner, Chicago, IL
"I manage 14 units and HVAC service is my biggest headache. Thermostat's contractors don't ghost, don't overcharge, and they actually respond to my maintenance coordinator. That's worth every penny."
Tom Reinholt
Property Manager, Columbus, OH
