Best heating and air conditioning pros near Mchenry, IL

"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."

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"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."

"I had my air ducts cleaned by TopTec and couldn’t be more impressed. Mostapha and Jesus were the technicians, and they were both fantastic — super professional, friendly, and incredibly thorough. They took the time to explain the process, answered all my questions, and treated my home with care and respect. The results speak for themselves. If you're considering duct cleaning, don’t look any further. TopTec is the real deal!"

"Very responsive,!and got to my place within the half hour. Dave is personable, and appears to know HVACs. Will use for ongoing annual maintenance, as well..."

"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"
