Hassler Heating and Air Conditioning, Inc. at 1537 South 56th Street, El Cerrito, California.

Super job--Chris from Hassler came out for the initial diagnosis of a defective circuit board and blower motor on our Day & Night furnace. Warranty parts were ordered and Chris returned for the installation and testing, problem fixed. Both visits were at the times promised and the work done was thorough and professional. Everyone at Hassler was courteous and very service oriented. Great company, highly recommended!

I have used Hassler on numerous occasions at both my house and my rental property. They run an exceptional operation in regard to bidding the job, installing the unit, following up on that installation and responsiveness if any unexpected problems arise. Trevor was incredibly great to work with. He is professional, listens carefully to concerns and he is very prompt. When he tells you he will be there in a certain timeframe, he appears. His work is clean, efficient and he leaves the job with "all bases covered." I don't usually give five star reviews, but my wife and I are very happy with the work performed by Hassler with a special call-out to Trevor.
