"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."

"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!!"

"Everyone from the sales person to installers were great. I love our new HVAC system!"

"Rob and Tim are excellent folks to work with, wouldn’t look anywhere else for my HVAC related stuff!"

"Dave and Brian did a great job installing my new AC unit and cleaning my ducts yesterday. They were knowledgeable and efficient and they cleaned up before they left. The cost was very competitive....Dave actually gave me a break on the duct cleaning because we have so many vents! I HIGHLY recommend Perfect Temp for duct cleaning and AC installation."

"One hour heating of lake villa went above and beyond. Furnace was making load noise when it kicked on. Completely obvious he knew what he was doing. They repaired it, checked for other signs of issues, and cleaned up the furnace. The cleaning was a job on its own since it has not been serviced or cleaned in about 8 years. Customer service was outstanding and understanding. It s a new home to us and in the past I always used to call the company with the sticker on furnace from previous owners. I will be using one hour heating from now on for all my Hvac needs. Thank you"
