Get matched with top air conditioning pros in Oswego, IL

"Replaced capacitor. Still didn't work, so we were looking at ac replacement. Before we did, technician continued to experiment by cooling of the compressor with the garden hose and it worked! Saved me thousands in replacement costs."

"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."

"Knowledgeable and professional air conditioning service"

"They were able to send out a tech to repair our AC pretty quickly (within a few days), even though this was during a bout of unusually high temperatures. The tech arrived towards the end of the given arrival window; even though he was still within the window, they called me that day to let me know he would be later rather than earlier, which was nice. The tech diagnosed the issue, and discussed options with me and fixed it (low line refrigerant, possible leak). All that was great, and prices seemed reasonable. The only negative part of the experience is that there was an extra charge to de-ice the frozen interior coils. I could have done that in advance if I knew I was supposed to (the tech seemed surprised I hadn't, or that I wasn't told to). Maybe that's obvious to others, but it's not that big of a deal, just an an annoying extra cost."

"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"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!"

"They came even at a busy time to assess what needed to be done. I was given plenty of information and my questions were answered. I expect tomorrow’s furnace instsall will go just as well. I have had ac units and furnaces installed by Miller and been very pleased. A fine company."

"I hired this company to clean and check my Air Conditioner for the summer. The service tech was on time, friendly and knowledgeable. He took time to explain everything by showing me what levels my unit was at vs where it should be and gave me good recommendations on maintenance. He performed the necessary work in a timely manner and at a reasonable cost. I would recommend Best Rates Heating and Cooling for all of your HVAC needs."
