Best Heating & Air Conditioning / HVAC In Downers Grove

“What a Blessing to have Kats come and install a new furnace in my home today! Giovani was very thorough in describing and showing me the failure of my original broken down furnace. His crew then came through to put in a new Bryant system and worked extremely hard to get everything perfectly installed in my home. Eddie and Louie were very polite, and hardworking. Anxious to do a good job you could tell. There promptness and hardwork allowed me to get everything done the same day....so grateful to them all, and happy to say my house is now toasty warm.

Following up on this message today to say, thanks again to Kats for coming out on my almost one year anniversary to do the annual clean/tune up. Luis did a great job along with being very polite and kind. Thanks for your wonderful service.“

“Jack and his apprentice Aidan (sp) came at the very beginning of the window the company had given me for them to show up. Jack did a great job repairing my kitchen sink. They are both very nice guys.“

“I’ve used Pro Air for both the installation and service on a split unit system for an addition. They were always extremely professional, courteous, and knowledgeable during every interaction. Always arrived when they said they would, and quick to respond to any issues or questions I had. I would highly recommend them for any of your HVAC needs!“

“John was thorough and explained what he is doing. Punctual and friendly, always go beyond his work to help. A good and kind person.“

“The technician was competent and performed his work well. Preventive repair/replacement of degrading components (capacitor and contactor) were recommended. The price for the parts was excessive, greater than ten times what was available from Amazon or other supply portals.“

“I called Stephens Plumbing and Heating after I was told by another company (that I have a service plan with for many years) that I needed a new HVAC unit ASAP. They quoted me around $15K, and when the tech left, he asked how soon I would be doing this. I told him it wasn't on the immediate horizon, and after showing pictures on how bad my furnace was, he said it should be. I called this group for a 2nd opinion, and the tech, David, said while I do need a new unit at some point, he eased my mind there were no safety concerns, like the tech from the other group said, and fixed a small part rather than replacing the whole unit. So $300 versus $15K? I'll call Stephens every time.“

“Thomas was professional and very helpful! He helped us fix the issue without trying to have us buy a new unit. Honest opinion and I appreciated that!“

“They were very easy to schedule, quick to fix the problem, and reasonably priced. Deangelo even took a moment to show me how to see if my dryer was producing heat so I can address it myself. Would definitely use for future issues with in home appliances“

“we used GSHA three years ago to install new furnace and air conditioner, we still call on them for anythings related to their services. we had problems with our water heater, Raymundo did a great job fixing the problem, he's very professional, knowledgeable, and efficient. I highly recommend GSHA, very courteous and professional team.“

“After taking a gamble on a new provider based on google reviews, I’ve now got a new HVAC provider I can trust. Jordan did a great, thorough job with relocating our AC unit, cleaned up nicely and was overall great and kind to work with. When calling to initiate the quote and scheduling, that process was just as easy with the staff as well. Thank you!“
