Cahill Heating, Air Conditioning & Electric

Cahill is great! Great service, pricing and professional! Will definitely use again!

First time using Cahill and I have to say they’re miles ahead of their competition. Not only was their service tech extremely informative throughout the entire diagnosis, he also did an amazing job. After spending years working with an HVAC company out of mundelein that recently closed, Cahill showed me the caliber of service I was missing. I immediately recommended my family to them as well.

When we called, Cahill answered. Our family appreciated their punctual nature, attention to detail, and down-to-business attitude

Have used these guys for years! Great service, local business & nice guys that know their stuff. Highly recommend.

Highly recommend Cahill Heating and AC. Very responsive and professional. Will definitely use again.

Cahill will solve your furnace / AC issue in a pinch. Straight shooters who know what they’re doing - highly recommend!

Cahill has done our AC and saved us from spending BIG money on a HVAC scam. We appreciate them and their honesty!

My tech was very courteous and professional. I would definitely recommend them to anyone!

Very responsive to my questions and as I’ve done due diligence on the market, it seems like they come in at a very good value.

I just had my first service call and it was great. He was very personable and explained a lot of things that I wanted to know but never asked. He had a lot of good pointers that will save me money on the long run. These guys really understand the value of a Trane system and just which I had used them for the original installation.
