I am really bad with names but the reason I can actually remember any of the names is because of how positive of an experience this was. They basically came out, diagnosed it within an hour and had the part replaced because they had it on hand in their truck. It was some kind of electrical switch. They tested the system and it's been working ever since! The price was very affordable and service was A+. I'll recommend this crew to everyone interested. They shook my hand and were very respectful gentlemen. Not to mention, if anyone goes on the Next door app, our neighbors in Lake Shastina neighborhood suggested Marcus and a "Raymac." Not just once, like a half dozen people and more than 80% of the comments were all about mountain Air and Marcus. Credit is earned where it is due. Thank you gents! ​​

I'm guessing my sink job was not a big enough money maker. Sad because they did a nice job on a water heater they did. But poor integrity to pick and choose jobs. I wouldn't choose them again.

My real estate agent told me about Will Johnson, describing him as a "prince of a guy". She was…read morenot exaggerating much. Will took care of about three afternoon's worth of electrical fixes/upgrades to my slightly older house, and didn't just make things work -- he did a beautiful job. Everything he installed looks and acts just perfect. I'm especially thankful that he corrected grounding issues on my outlets: within a month, my carpet cleaner started gushing fluid out the motor vents due to internal failure -- I was like "glad I made sure the outlets are grounded!". And a month later, the roofer guy was up there with his electric nail gun, and it suddenly started raining -- "glad I made sure those outside outlets are GFI!". Will seems kind of busy sometimes, but if you can get him to do a job for you, I think there's a very high likelihood you will be as happy as I am.

Even though he was very busy, he came out as soon as he could. He showed up on time for our appointment in a clean organized truck,.

He was very thorough and persistent in locating the problem. Turned out we needed a part, which he ordered and installed the day after it came in. In addition to being knowledgeable and professional, Ernie is a very likable person. We're very grateful to him for getting to us as soon as he could because we do not have a fireplace or wood stove.
