Located in Cleveland Heights, brothers Verne & Ellsworth Hann started their HVAC business in 1952. They were among the region’s first to develop expertise in newly popular central air-conditioning. Ellsworth’s son, William A. Hann, took ownership 21 years later and expanded with plumbing, whole-house re-piping, and innovative service contracts that gave customers worry-free maintenance.
Terrible experience we paid $400 dollars and the boiler doesn’t work. I called and they offered no help to fix other than I have to pay another $400 for them to even come look and see they didn’t fix the boiler

Smooth and positive experience from beginning to end. Booking was easy, Les was on time, friendly and super knowledgeable. And our shower works perfectly! We need a bit more work done and I’ll be calling here again. Thanks!

Thank you Verne & Ellsworth Hann. Had Bill R. and associates remove and replace my 20 year old boiler with a new one. They did a great job! They showed up on time, we’re thorough in explaining how the new equipment worked, did the removal and install quickly (1 1/2 days), and cleaned up completely. Thanks again fellows! Plumbers rule😉👍🇺🇸

Vernes, Ellsworth, and Hahn serviced our church heating system. Sean was our service representative and he was polite, professional, and cleaned his area after service. We are completely satisfied and appreciative for his visit today. We will continue to use this company for all of our heating and cooling needs.

I called at 11:57 am because my hot water tank would not light and by 1:50 pm Brian A had arrived, assessed the problem and was able to light the tank. He did advise us since it is 13 yrs old it might go out again and then it will have to be replaced. This is the 3 rd time we have had Verne & Ellsworth to our home for different issues. We have found ghrvtechnivisns to be informative, knowledgeable and efficient. Thank you Brian A!!!
