Grant is awesome ! He went the extra mile for us and performed some on the spot tweaks (outside of the scope of the fall maintenance that we were scheduled for) to our unit to make it less noisy. He took time to explain things as well.

We called for an appointment to have our HVAC system checked and they came out in 2 days. Grant checked the system and did a thorough cleaning. He did try to sell us unnecessary stuff and the unit runs just as good as it did when we purchased it four years ago. I would recommend Reasonable Air, LLC to anyone thinking of purchasing a new unit or just needing their current system maintained.

I was told I needed to replace my entire unit by the first company that had come out to service it a few times. I got a weird feeling the last time they were out and made my calls. This is where I landed these amazing people!! He came in, didn’t rush, and figured out what was wrong. Lo and behold, I didn’t need an entire unit!! Thank goodness. We’re up and running again and my house feels amazing!!
Thank you so much!!

Grant and Reasonable Air did a great job installing a mini-split for our FROG. They came when they said they would and made sure everything was cleaned up before they left. Price was less than I thought it would be. Definitely recommend if you need any A/C work.

Under-promises and over-delivers. Grant was early to appointments, but called and asked if that was ok. Work came in very close to estimate and time allotted even though he found more components to replace and had to go get an extra part at his shop. The only difference I paid was for actual parts (and like a good, tradesman, he gave me the defunct ones and the packaging for the replacement to show the work was done). He'll be our go to from here on out.
