What our customers are saying

Josh S, Ashtabula

Very smooth and efficient experience. The technician told me which options were the best fit for my home. In the end, I had a new system that kept up with the heating and cooling demands of my house at a very reasonable price.

Randy Cooke, Chardon Custom Polymers

For years I struggled to find an HVAC Company that could take care of all of our facilities needs in a reliable, cost effective and professional manner that took the time to understand what we needed. Have, Inc. is a true one stop shop with very knowledgeable and efficient employees from the top down. It’s comforting to know when Have, Inc. is involved there are no worries from projects of any size to routine maintenance.

Marc W, Ashtabula

Earlier this summer my HVAC unit started to blow hot air, it was 3pm on a Friday and temperatures for the weekend were predicted in the low 90’s. I placed one call to HAVE Inc and had a service technician at my house before 5pm and a solution to my problem within 30 minutes. That one call made all the difference for my family and we will continue to be HAVE Inc customers forever. Thanks HAVE Inc.!
