"This was our second call to All Temp for service. Mike was our technician and he is very knowledgeable and professional. He gave some good advice on cooling our house, what to look for in the HVAC system in a new house (we are looking), and didn't try to up-sell me on things we didn't need. He was quick with his assessment and work. We'll be calling them again if we have HVAC issues."

"The technician did a very good job cleaning the hvac ducts."

"HVAC machine outside wasn’t working. Ricardo ? was so good at explaining & suggesting his expert ideas. There was a mouse & nest inside the machine & wires were severed. He removed the critter & nest & repaired the wires. All is working again. What a great guy he is!!"

"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."

"professional & courteous service. Explained what they were doing and how to improve my HVAC system"
