Get matched with top central a/c service or repairers in Waukegan, IL

"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."

"My technician GelAsio was prompt and very professional. The home had the heat turned off by the gas company because a plumbing part needed to be replaced by a plumber. Once that was done I needed a hvac professional turn the heat on. The technician was really good and answered all my questions about the system. It’s my elderly mom’s home and she was out of town. I will definitely use their services again in the future. I had called Sears repair twice and when I was caught in traffic they cancelled my appointment. Sears is a bankrupt company so stay away from them. Use a professional company like All Temp that does a great job for a fair price."

"Excellent service from start to finish. The technician handled our thermostat installation and central A/C repair quickly and professionally. Everything is working perfectly now and the whole process was explained clearly. Very reliable team and highly recommended."

"The owner came out and repaired my furnace. He was professional and very helpful and quick to explain everything. I would recommend them without hesitation"

"The only time they had available was in the evening so I had to pay double the amount or a regular service call. I agreed to that because the temperature in my house probably around 40°. They gave me a timeframe for service from 5 PM to 9 PM and a service person would call when on their way. I was thrilled that Brett called me at before 5pm. Brett was very professional and thorough. He walked me through what needed to be fixed and prices. Within less than 35,minutes he replaced my broken igniter and answered questions about my desire to replace an 18 year old furnace."

"The service was well done and thorough! Air is running nice and cool. Thanks a million!"
