Get matched with top central humidifier installers and replacers in Bellevue, WA

"Mike did a thorough job and fixed the whistling noise in our vent. Very professional and took time to do quality work."

"Our old gas furnace died during the series of snowstorms in February. Stephan came out the day after we called, to give us the bad news that the unit was so old, no replacement parts were available so the whole thing would have to be replaced. Not really surprising given the age of the unit. He also showed me where the water heater (of similar vintage) was corroding around the outlet pipe, so was also in need of replacement. Kris came out within a couple of hours to look over the house and recommended a couple of options. We were leaving town so installation was delayed a couple of days; otherwise we could have had everything done within 48hours of the initial call. The crew that showed up to do the installation (sorry I forgot your names) showed up promptly at 8AM, worked throughout the day, and left our basement cleaner than it started out."

"Crew was very prompt and professional. Took care to put booties on whenever entering the house and courteous of your needs. Very nice, professional installation and site picked up and cleaned after completion. Thorough walk through and explained any questions don’t hesrtate to call and they will be more than happy to come back out and help."

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"I wanted to pass on my experience with Evergreen who went the extra mile after my Mitsubishi slim AC started leaking water before the hot summer months. I had called a Kirkland company who came out diagnosed the issue and charged me an exorbitant amount. However after I informed them it was registered and parts were under warranty they dropped me like a hot potato and never called back. On the other hand Victoria at Evergreen called me regularly to update on the warranty and parts and scheduled a full day repair with Jesse, an excellent technician. He used appropriate PPE, educated me about the problem, even provided less expensive options, and finally completed the long arduous process of replacing parts and recharging the refrigerant all for a reasonable amount. Voila AC again! I would highly recommend this company - to do your job efficiently and technically correct, without overcharging or trying to upscale you. Peace of mind is priceless. RobinM"

"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"First off wanted to say I don't write reviews but felt compelled to do so for this. My gas furnace stopped blowing hot air. Trouble shooted the issue myself and thought it might be a bad gas valve. Not wanting to deal with a gas valve I called different companies and ended up choosing Air Pro's due them being a Local Company, Their diagnostic fee is very reasonable and when talking with them just getting a good feeling. Jerry came out a day later and sure enough it was the gas valve. He ordered the part and it came quickly. He installed it and the furnace was back up and running. The cost came out to about what was quoted to me when I talked to them the first time. It's ALWAYS a good sign of a good business when their actual cost/bill comes out what they told you! Here is why I'm also writing the review. About a week or so after Jerry replaced the valve, we noticed a slight gas smell. I called to have someone come back and check it out. Jerry called me within 30 min to ask some questions. He was off for the day and I could tell he was home but he drove 45 min to come back to our house. He was able to determine there was a small leak at the pipe around the gas valve. Given this was Air Pro's error the fact they came back right away and dropped everything was GREAT customer service. I would definitely hire Air Pro's again!"

"Cory and Joe were fantastic. The installations went without a hitch. The overall cost was lower than three other quotes I had received for the job. At the beginning of the A/C install I noticed the water heater was leaking, and they were able to replace it the next day. I will definitely use them again."

"Northwest expert was outstanding and delivered on the Tune-Up on my central HVAC just as they did on the installation 2 years ago. Virgil was thorough and professional!"
