They educated us on different units and compared them. Recommended a Uv light and we also added on a 4” filter which have helped with dust in our home. No BS upfront company and you can tell the employees know what they are doing. Highly recommend them.“

“AC Unit Replacement Review

I recently had my AC unit replaced, and the experience was excellent. The initial consultation was clear and transparent, and the installation was scheduled conveniently. The technicians were punctual, professional, and cleaned up thoroughly after the job. The new unit cools effectively, operates quietly, and has already reduced my energy bills. The follow-up support was a nice touch, ensuring everything was running smoothly. I highly recommend this company for AC/HEAT unit replacements.“

“Always on time, professional, courteous and reliable. Been a customer for 12+ years and wouldn't use anyone else for HVAC or Plumbing!“

“They cleaned my dryer vent fast with no problems. The 2 men that came were very nice. I do recommend Sai Air?“

“Excellent, competent service. Patrick is very good at what he does, and diagnosed the problem that the other service company couldn’t. High recommendation.“

“Jeremy and his team are responsive, professional, knowledgeable. We were having major issues with our boiler (constantly getting airlocked). He knew exactly what to do, how to fix it, giving us multiple options for how extreme we wanted our updates to the system to be. When, after the work, it wasn't working exactly as smoothly as we had hoped (it was heating, but there was some unevenness in the system), he and his guys came out again and modified the work to resolve the issue completely. These systems can be delicate and touchy and I really wouldn't trust anyone to work with our boiler system except NorthSide. 100% recommend.“

“Cayhill is always excellent. Heiko does a very throrough job. We have never been disappointed by anyone At Cahill!“

“Amazing service. We were in a bit of a situation and Pasquesi was able to send Joe out. He was here within 20 minutes, and was able to effectively and efficiently fix the issues. Joe also went above and beyond in explaining everything he was doing and how he was going to help. We are customers for life. Thanks Joe and Thanks Pasquesi“

“GMS Heating and Cooling of Morton Grove Illinois, was recommended by a family member. I lived about 40 minutes away and they were happy to drive out for an estimate. I had them install a new York Furnace, Condenser, and Coil. They did a fantastic job! I was pleasantly surprised a system humidifier/dehumidifier was also installed as I had overlooked it. I can pass on my portable room unit. They uninstalled the old rusting equipment from the 80s, which created a huge mess through the basement, stairs, and garage, which they cleaned up and left spotless! They were very knowledgeable and professional, answering all my questions. When I went online to register my warranties, they had already done it for me! I couldn't be happier and highly recommend them! I'm terrible at remembering names, but Thank you so much!“
