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

"Jim did a great job of informing me of what he was doing, diagnosing the problem, and recommending options to repair or replace our heat pump."

"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."

"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!"

"Evergreen installed a new hybrid heat pump system in my house. After researching the options, Evergreen was not only the most reasonable price, but they also scoped out a hybrid system where they would install new duct work and a single air exchanger in the attic and a minisplit in the basement. Scott, the sales person, did not try to upsell me on number of zones (others tried to get me to get 2 units in the basement) and after 2 months with the system, the single unit in the basement is heating the whole basement to our needs. All this was done at a price still considerably lower than the "standard" system price being offered by one of the bigger, similarly named companies. Evergreen was also the only company to propose a hybrid system where they would install a single exchanger in the attic and run new ceiling ducts to the rooms. This was appealing because we don't need to have the cassettes in each room and we didn't need to line the outside of the house with conduit for the cassettes (also the bathroom gets heat, too). Scott was great to work with, answered all my questions, and did his best to size the system correctly. Installation was smooth. There was a small hiccup where the installer accidentally broke a basement window, but Evergreen squared it away. Don and his team were great and the inspections passed. After install support has been great. Denise has been responsive to my questions. Overall, the experience was great with Evergreen and I highly recommend them."

"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!"

"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!"

"Professional and thorough! Got my leaking water heater replaced pretty quickly!"
