I'm writing to thank you for your work in providing air conditioning for my house. Given the particular structure and setting of this modernist, flat-roofed house, with its open rooms and glass walls, it was unclear what type of system would work here.

The condenser unit at our house went out the Sunday before Labor Day, just before a week of 100 degree days. I called Hassler and was surprised to have someone pick up the phone, and happy to be able to schedule a next day appointment. Mike came today, was right on time, and quickly... Read More

Chris just came out and inspected a furnace and ducting for me at a property that clients of mine are purchasing in El Cerrito. He was very knowledgable and was sure to take the time to answer all of my questions thoroughly. I would definitely use Hassler again based on the service he... Read More

Hassler Heating and AC really pulled through for me. I'm a landlord and one of my tenants reported that the HVAC system went completely out right during the hottest week of the year. Hassler Heating and AC was very responsive and understood my sense of urgency to respond to my tenant... Read More

Fantastic company to work with, great service & reasonable prices! We moved into our current place & the air conditioning conked off within weeks! We interviewed & got quotes from several companies, Hassler gave us the best deal by far.

Mike, apparently Rene and your team did such a good job the rebate is even a bit higher than expected. Thanks for the good work.  Your commitment to qualifying and getting the rebate was a key factor of why my wife and I chose your company for the installation over other companies... Read More
