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

"All went according to plan. Justin (hope I remember that right) was promptly at my home on Saturday morning. He explained what he was going to do (check the furnace) and verify operation (he found two contactors/relays that were starting to age and recommended replacement soon.) After doing the furnace checkout, he proceeded to get ready to go under the house. We laid out a large covercloth to prevent dirt on the carpet and down he went. All said and done he had the main bedroom vent open (it was jammed by the vent cleaning company) and provided me an option on the air leak. The technician Justin was friendly, explained things completely, was always respectful of my home and me, and was a pleasure to have do the work. He obviously knew his job and completely answered all my questions."

"Everyone I came in contact with was a delight to work with, from Ryan H., to Tyler, to the 2 service installers Dustin & Riley, to their supervisor Ryan & the receptionists! I highly recommend, as the work was done professionally & efficiently by courteous, motivated, happy employees and at the price quoted. This experience was a breath of fresh air after the 12 year nightmare with my old unit (a different company) that they replaced for me. I anticipate lower electric Bill's also, as the new unit operates effortlessly & much quieter compared to the old. I don't mind the price as much for the quality of product and service. Thank you all! Peggy"

"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!"

"My experience with Greenwood Heating and Air Conditioning has been entirely positive. From my free estimate appointment through finished installation, the process was seamless. Each and every representative of theirs has been exceptional. Trevor negotiated a very competitive, all inclusive price for the entire system and followed up on the day of installation to see how everything was going. The install was expertly performed by an industry pro, Andril, with 17 years plus experience. Follow-up has been exceptional. Greenwood Heating has earned my unequivocal recommendation."

"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 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"

"They set an appointment, were timely, reinspected my furnace first to see if the problem we were told was correct, prepared me a great quote and came back that same day and installed a new furnace. Very nice people with excellent service"
