HVAC services in Boise and the Treasure Valley
Whatever is keeping your home from being comfortable, one of our technicians has fixed it before.
Air conditioner repair
Warm air, strange noises, frozen coils or a unit that will not start. We diagnose it on the first visit and carry the common parts on the truck.
Furnace repair
Gas and electric furnaces, igniters, blower motors and thermostats. Fast fixes when the first cold snap hits.
Heat pump installation
High-efficiency heat pumps sized with a proper load calculation, with rebate paperwork handled for you.
Seasonal tune-ups
A 21-point inspection each spring and fall that catches small problems before they become emergency calls.
Duct sealing and cleaning
Leaky ducts can waste a quarter of your heating and cooling. We test, seal and clean them.
Indoor air quality
Whole-home filtration, humidifiers and UV purifiers for dry Idaho winters and smoky summers.

What Boise homeowners say about us
Real feedback from customers across the Treasure Valley.
★★★★★
Our AC died on a 102 degree Saturday. Tallgrass had a tech at the house in two hours and the unit running by dinner. The price matched the quote exactly.
★★★★★
Replaced our 17-year-old furnace and added a heat pump. Dana walked us through three options without any pressure, and the crew left the house spotless.
★★★★☆
On the Care Plan for two years now. Never had an emergency call, and the spring tune-up found a worn capacitor before it failed. Scheduling can take a day or two in July.
