Diamond Heating, Cooling, Plumbing & Electric delivers expert home comfort and essential services to Boise families and businesses with integrity, skill, and around-the-clock availability.

Diamond Heating, Cooling, Plumbing & Electric was founded on a straightforward principle: Boise homeowners deserve reliable, honest service when their essential systems fail. From our earliest days, we recognized that heating, cooling, plumbing, and electrical emergencies rarely happen at convenient times. That understanding shaped our commitment to true twenty-four-hour availability and our determination to build a team skilled enough to handle any residential challenge with confidence and care.
Our approach centers on transparency and craftsmanship. Every technician arrives fully equipped and trained to diagnose problems accurately, explain options clearly, and complete repairs that last. We invest continuously in education and equipment because Boise's climate and housing stock demand both traditional expertise and current knowledge. Whether restoring heat on a January night or diagnosing a complex electrical issue, our team brings the same meticulous standards to every call.
As a local company, we understand the neighborhoods we serve and the systems that keep Boise homes comfortable and safe. Our reputation rests on thousands of satisfied customers who trust us during stressful moments and rely on our maintenance programs year-round. We take that trust seriously, showing up when promised, respecting your home, and standing behind our work with solid guarantees that reflect our confidence in what we do.

“We replaced all of our plumbing and our HVAC in a 1950s home in the North End earlier this year. I spent a tremendous amount of time getting bids and researching and hands down these guys came out on top. They listened, answered all of my questions and made sure that we received the best service. Everyone who came into our home was professional and an expert in their field. These guys are pros, not salesmen. Diamond easily gets my highest recommendation. Jay Perez at Diamond is the person I worked with to get the ball rolling with this huge project. Thanks again Jay for everything!”
