I got several quotes from other companies and theirs provided best value. They didnt try to over sell. Frank, assisted by Mitchell and Eddy did a great job replacing my equipment in only seven hours. It was just starting to get warm and they had me going just in time. Ours was at the end of its life, and so glad we decided to replace it before it failed. Great team work and polite installation.

Seems like survey for previous visit popped up.

I had some major heating issues recently and Infinity AC were really quick to respond. Technicians Nick and Frank came by and inspected my heating unit which needed to be completely replaced. They came back two days later and installed the new unit in a shorter time than I was quoted. They were knowledgeable and explained the problem clearly. They were really respectful of my space and highly professional. Id recommend this company for any HVAC issues!

I hired this company to install a mini split in my home and they went above and beyond my expectations. On top of that, they were extremely fair in their pricing as I had called numerous other companies, and I chose them because of their fairness, professionalism and now their work ethic. I will use them again! They are awesome.
