Get matched with top air conditioning pros in Hillside, IL

"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"Andrew and his assistant were very professional in their approach to cleaning our air ducts and dryer vent. The services they provided were totally consistent with how they describe their approach to the service they provide. This included the very helpful before and after pictures taken which would convince anyone of the need to have this work performed in their homes."

"They were prompt, friendly and knowledgeable. The problem with my A/C was explained to me clearly and I was back in cool, air conditioned comfort in no time!"

"The air conditioner is working fine."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"We called United Heating and Air Conditioning for an annual furnace inspection for our new home. They scheduled quickly and easily. We then had a conflict and they re-scheduled just as easily. When they inspected the furnace it turned out it was extremely old and no longer safely operable. We required an emergency replacement. This was in November and we didn't want to be without a furnace. United Heating and Air Conditioning was able to come the next day (!) and install a new furnace. They took care of the installation, confirmed it worked, and hauled away our old furnace. They were quick and professional and stuck exactly to the quote. We were extremely satisfied and will definitely be reaching out to them when it's time to check (and possibly replace!) our air conditioning unit. Highly recommend!"

"I called yesterday and Ron came out today. This is the 3rd time he's helped us with furnace or central air issues. He found a sticker wrapper by the filter and found that the filter was the wrong size. He's always really friendly and professional.
