C - Western Springs, IL 60558
Great Service !!
This review isn’t directed at Mark, but at Carrier. My AC broke down for the second time in four years, even though I replaced it with a brand-new unit in 2020. We encountered the same problem again and had to pay $750 for the service. Typically, these units are expected to last 10-15 years.

Tom - Bolingbrook, IL 60490
Very friendly service
Although at times I still hear the clunking in the HVAC duct work, it seems to be less then what I have heard in the house previously. So not 100% resolved.
Tony - Lemont Township, IL 60439
Problem Solved!
I had bought a new townhome and every day I kept hearing this strange noise. No one could figure out what the heck it was. Mark from Tempco watched the video I had and knew what it was and fixed it! I am so grateful to Mark. He has helped get a few other small problems with the new home heating system worked out. I would recommend this company for sure.
