"Hired Mike to replace a heater and install a new air conditioner. The team did an outstanding job. They were professional, reliable, dependable, fast and left the area cleaner than when they started. Any questions I had after installation were answered quickly and they even came out to install a new filer for me a few times over the years. I did a lot of research before I hired them and I am happy that I made the right choice. 
I HIGHLY RECOMMEND HASSLER!"
