Jonathan O

On both instances of working with this company, both guys showed an encyclopedic knowledge of AC systems in general and everything around it. These guys are the professionals among professionals and I have dealt with a lot of them. They explained everything in detail as they worked so I knew exactly what was going on and learned a lot about how my AC system works, which is helpful. The quotes they have given me come in just underneath the other companies as well, so it's no wonder they're busy.

Dan G

I had 3 HVAC companies over during the holiday weekend. 2 companies said they couldnt fix until monday. Rest assured not only fixed it, but stayed until 915pm to fix. They also said they would give me credit for the piece if I replaced my unit (which i needed to..20 yrs old). I have recommended them to neighbors and co workers and I cant recommend them enough for a trustworthy and price friendly company.

Owner's reply
Thank you so much, Dan! We’re glad we could help during the holiday weekend and truly appreciate your recommendations. It means the world to us knowing you found our service trustworthy and reliable. - Rest Assured HVAC
