Mercer Island, WA HVAC Experts

"Over the past couple of weeks we have used ExactAir for both an emergency call out as well as a new furnace installation. My wife and I were very impressed with the way Rylan communicated with us as well as his technical knowledge and skill. We especially appreciated his help in choosing our new furnace and thermostat. The work was done on time and to our schedule. If you looking to replace or repair your furnace, I would put ExactAir on the top of your list of HVAC contractors."

"ExactAir Home Comfort replaced a hot water heater in 2024. A professional job and Rylan is great to work with. Had to call him yesterday for a pressure valve that was leaking and wouldn’t reset. He came right out and replaced the valve which had cracked seal. Will call him when I have more HVAC or plumbing jobs. A+++"

"ExactAir did an amazing job replacing our old furnace and installing a new heat pump. They’re very easy to work with and explained everything upfront so there were no surprises. The whole process was quick and smooth, and my family and I can already feel the difference — the house warms up so much faster now! Their work is top-notch, and I would absolutely recommend ExactAir to anyone looking for quality HVAC service."

"We have always had excellent experience working with Ryan at ExactAir Home Comfort. From installing a water heater to setting up a generator for our new house, the quality of work was always outstanding. The communication was clear and professional throughout. They paid extra attention to details and make sure everything was done right. Highly recommend to everyone!"

"I honestly can’t say enough good things about this company. From the very first conversation, I felt like we were dealing with people we could genuinely trust—and that alone is huge when it comes to HVAC and plumbing work. Their pricing was very competitive, and what really impressed me was that the final bill was exactly what they quoted. No surprises, no last-minute add-ons, and no fine print. What stood out most was their honesty. They never tried to upsell us—not once. After dealing with contractors in the past who felt more like used-car salesmen, this was such a refreshing experience. We felt comfortable asking questions and confident in every decision we made because nothing ever felt rushed or pressured. They installed a variable-speed American Standard heat pump along with a Platinum variable-speed, two-stage American Standard furnace, and the system has been incredible. The comfort level in our home is noticeably better, and the efficiency has exceeded our expectations. They also added a Honeywell electric air cleaner with a UV air scrubber, and we can truly feel the difference in our home’s air quality—it’s cleaner, fresher, and just healthier overall. In addition, they installed a tankless water heater with a recirculation system, and it has been a game changer. We now have endless hot water and almost instant hot water at the faucets, which is incredibly convenient. No more waiting, no wasted water, and improved energy efficiency—it’s one of those upgrades you don’t realize how much you’ll appreciate until you have it. This company does things the right way—professional, honest, and high-quality work from start to finish. I would recommend them without hesitation to anyone looking for trustworthy, skilled professionals who truly stand behind their work."
