Smart thermostat installation in Foxfield delivers some of the highest energy savings in the country because Colorado's extreme temperature swings create more opportunities for automated optimization. A thermostat that learns your schedule and uses geofencing can save Foxfield homeowners $130-200 per year. We install Nest, Ecobee, Honeywell, and Emerson Sensi thermostats with complete wiring, Wi-Fi setup, schedule programming, and a walkthrough of all features. Many older Foxfield homes lack a C-wire — we install one as part of the service at no extra cost.
Like most Denver metro communities, this area experiences hot summers exceeding 90°F, cold winters dropping below 0°F, and rapid temperature swings of 30-50°F in a single day. The high altitude (5,200+ feet) requires all gas furnaces to have proper high-altitude combustion adjustments.
Our technicians serve all Foxfield neighborhoods including various residential areas. Whether you're in a newer development or an established neighborhood, we have the expertise and licensing to handle your HVAC needs.
Regular maintenance is the single best way to extend your HVAC system's life and avoid emergency breakdowns in Colorado's demanding climate.
