Been working with Ray and his crew for years at my house. They kept an old unit going and got me a new one when it was time. Very helpful. Very honest.

I can honestly say that this company is the best!! I am so pleased with everything that they have done from diagnosing the problems with my old heat pump, installing my new heat pump and cleaning my vents. I am 100% satisfied with their communication, responsiveness, work, and price! Ray and his team have been great! I will continue to use them for all of my heat and air needs. Thanks again, Ray and team!!

Cost was reasonable. We found the owner to be honest and a man of his word. His crew installed and test our unit. We have light cream almost white carpet. The crew did not make a mess and our carpet wasn't soiled. I also recommend this company to my neighbor. Their outside exhaust pipe was setup incorrectly not setup to code. This company came out quickly to fix the problem.

We have used Assured Comfort twice (old house and new house) for new HVAC units and will continue to be happy, faithful customers as long as we have heat and air needs. Every time we've called, Ray or one of his crew are here that day or the next. They are always friendly, professional, prompt, well knowledged, and not only is their work top notch but they quickly it done.

I called Assured Comfort on a cold Sunday when my furnace went out. They came in two hours, diagnosed the problem, ordered the parts, and had me fixed in 24 hours! Super affordable!
