Great Service every time I call Greenely. He listens to your idea of what you believe is wrong with it works from there. Fast friendly service and above all he does not overcharge like many other companies do. Sad to see the same exact person gave him 2 negative reviews over something he could have easily remedied...Grow up Pamela

John is very responsive and helps you understand your options of repair versus replacement.
Kelsey B.
John and his crew replaced our furnace recently. He was quick to get us on his schedule, communicated clearly, and showed up when he said he would. He was personable and professional and did great work. We were up and running in a day. Would absolutely recommend!
Bob W.
He is there to help with your needs at a very reasonable price. And he is very proffesional.

John is the BEST! Every time I’ve needed my HVAC system serviced, he’s been quick, efficient, and affordable. Plus, he's very responsive, trustworthy, and never forgets about you. He always has a great attitude and is willing to help whenever I call. Highly recommend!
Gary K.
John was prompt, fixed the problem, didn’t upsell me, and the bill was the most fair I’ve ever seen in the repair business.

hands down the best heating and cooling ever in the cedar valley.
Ervin S.
Probably one of the most honest technicians I've seen in a long time. Prices are very reasonable and he'll actually fix your furnace rather than suggest you purchase a new one from him. It was thanks to him we actually found out the furnace we had had a 40 year warranty on the part that failed and the previous tech we'd called before neglected to mention that. He was very personable and would absolutely hire him again and will do so in the future.

I called John Greenley to take advantage of his $25 Spring air-conditioner check up. He responded quickly and did a thorough job. He found I had some small coolant leaks and discussed the options for dealing with them. I found John to be professional, knowledgeable, and thorough.
Bob W.
I had an excavation project to start, and I needed to remove and set aside the outside AC unit. John came over the next day and disconnected the unit and moved it out of the way. When the excavation project was finished, he came back and bolted it on the outside wall and reconnected it. The AC works like a dream and it
looks awesome up out of the way for future landscaping. I couldn't be any happier with his professionalism. And he accomplished it all with a very reasonable and fair cost.
Joe D.
I called for my 77 year old mother who's furnace was not working. John got it her house that day, diagnosed the problem, got a new part and fixed it the same day. Thank you for treating my mother so well.
Joseph P.
I called Greenley on a Sunday when I had a boiler emergency and quickly came out to help. He did a great job and was quite thorough! He was knowledgeable and showed me ways to maintain my boiler system. It is rare to find someone that is fair and honest when it comes to repairs.
