Get matched with top central a/c installers in Vernon Hills, IL

"Very well. The technician seemed well trained. He went through all vents and registers meticulously. Cleaned the furnace base unit thoroughly. Showed all the filters which needed to be cleaned, dried and re-installed."

"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"The unit was installed a couple of years ago. This visit was for spring checkup. Thomas, the tech, was great. Informative and efficient. I highly recommend this firm."

"I recently had a cooling system installed by Top Tec, and I couldn’t be more satisfied. Their team provided excellent service from start to finish—professional, efficient, and very knowledgeable. One thing I really appreciated was their price match guarantee, which made the entire process stress-free knowing I was getting the best value. The installation was smooth, the technicians were courteous, and everything was done right the first time. I highly recommend Top Tec for anyone in need of a cooling system. Great service, fair pricing, and reliable results!"

"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."

"This was routine preventive maintenance of my central A/C ARS is very professional and did a thorough testing and inspection of both my systems."

"I hired Full Efficiency to do the spring tune up for our central AC. Carlos arrived on time, wearing PPE, got to work right away with the spring tune up, and cleaned up after himself when he completed the job. He is a very professional, friendly man. We plan to have him back in the fall to prepare our furnace for the cold weather months!"

"Retracting my previous rating on 02/19/2021. The Tech was good, he fully answered my questions. The furnace is working very well. I has a misunderstanding with the filter replacement, however speaking with the Customer Care staff the matter was immediately cleared and I am happy with the results. I plan to hire Four Seasons for more projects as in chimney cleaning and installation of central ai."
