Honest pricing
Flat-rate quotes approved before work starts. The price you see is the price you pay.
Washington and Idaho's home for HVAC, plumbing, electrical, and drain service — built around licensed techs, flat-rate pricing, and the written Home Comfort Guarantee.
Our Story
Mainstream Home Services has spent decades doing one thing: making homes in Spokane and Coeur d’Alene more comfortable, safer, and more reliable. We’re not a national chain or a sub-contracting front. Every technician who shows up to your home is a Mainstream employee — licensed in Washington and Idaho, background-checked, drug-tested, and on a payroll with real benefits and a clear career path.
That’s the difference you feel when something breaks at 2am. You get a real dispatcher, a real ETA, a real licensed tech, and a real flat-rate quote — not a callback service, an automated phone tree, or hourly billing that grows the longer the visit takes.
We’re the team thousands of Inland Northwest neighbors trust for HVAC, electrical, plumbing, drains and sewers, and indoor air quality. One call, every service, all backed by the written Home Comfort Guarantee.
