"My furnace was installed by someone else that did a very poor job. I could not replace the filter without smashing it and smashing the new one to put in. Ridiculous! I had All Temp come out and they were able to do a quick fix so I didn't have to struggle with it anymore. He was on time, pleasant. He even put up with my dog wanting to say hello to him, Definitely would hire again!"

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."
