"Excellent. The service rep gave me many helpful maintenance tips to keep my HVAC appliances in top condition. He was prompt (actually early), well-organized, and communicated his findings well. I would definitely use All Temp again."

"Great communication when scheduling the appointment to have our furnace inspected, HVAC vents cleaned, and dryer vent cleaned. Their technician was polite, professional, and efficient."

"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!!"

"Work was done quickly and the HVAC technician was very helpful."

"Rick came to my home and gave us a proposal to remove and replace our old furnace and electric water heater. His cost was more than fair. Craig came early on the scheduled day. In no time he had the old equipment removed. The new equipment installations were all completed the same day. My experiance with C.R. Mechanical Services was better than expected. Rick and Craig were both friendly and professional through-out the whole project. I will highly recommend them for anyone in need of a HVAC contractor."

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