"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."

"Excellent, timely, and knowledgeale service. I had them come to clean the air ducts, but they were able to comprehensively answer some other questions I had about my HVAC situation. I am going to use them from now on for my HVAC needs. Recommend!"

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"I recently hired them for central A/C installation and furnace replacement, and the experience was excellent. The team was professional, arrived on time, and completed the work efficiently. Everything is running perfectly now, and my home feels much more comfortable."

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

"Initial estimate was scheduled with no problem, they took the time to answer all the questions I had about the furnace replacement. I received estimated from 6 other HVAC companies and American Family was basically the lowest, but I also felt comfortable with the level of knowledge and experience that was conveyed at the estimate. I scheduled the install and was a bit disappointed that the installers did not show until 10 am or so, but that was not a big problem as I had assumed the job would take all day. The job took longer than expected (past 7pm) and the installer wound up having to replace an entire part of the intake duct work that he did not expect to, but in the end the unit and ductwork looked clean and sturdy and well intalled. The owner called for a follow up appointment and he came in to look at the install and make sure all the settings were correct on the furnace. He answered any questions I had at that time. All in all a good experience with a good company"

"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."
