Mike Hammer was recommended by some friends. Our son and his family live in Martinez and we wanted to use a local tradesman to replace their old (very old) system.

We got some proposals by several companies in the area and decided to use Mike at Hammer's Heating and Air Conditioning. His proposal was clearcut and fair. He installed a Trane unit and did the job cleanly and on time. He answered all the questions we had.

I would not hesitate to use him for any HVAC work.

We recently had a new mini split system installed in a back ADU, and the entire experience with Mike exceeded our expectations. From the initial consultation through the final installation, he was super knowledgeable. He took the time to help us pick out a product that would best fit our needs and budget. He was able to install it that week and was very communicative throughout the whole process. The finished product looks great and 100% would recommend him for all your AC needs. 5 stars!

Hammer's Heating and Air Conditioning, was a great experience from beginning to end! I contracted Hammer's to install a new hvac system in my home. The quality of the hvac components provided, coupled with Mike's installation and professionalism cannot be beat, all at a great price point. Everything went extremely well, even when he encountered those problems that inevitably come up with an aging home, Mike was able to handle them with ease. Mike was extremely knowledgeable and helpful. If you need help with an hvac issue, Hammer's hvac is the company to call. 10++ I could not be more satisfied! Thanks Mike!
