"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 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."

"Replaced the original AC Unit(at least 25yr old), added a new humidifier to furnace and a new smart thermostat. The original guy who did repair work, Phil, was knowledgeable but at the end of the day wanted to sell anything he can. He had convinced me I was able to get rebates through ComEd for upgrading AC unit and adding the smart thermostat. At this time, I have been unable to get any rebates because he failed to mention I need to also have a furnace that qualifies and there was no receipts on the thermostat to claim that rebate. The day of the install, the guys that were here, did great work. They installed everything and added a damper to furnace(which does not work that great). When the guy installed the thermostat, he installed the wrong one and i had to show him the work order for the correct one. He left and it took a week for him to return to install the correct one. He also left with all the boxes."

"Marcos and Roberto provided excellent service. They identified an issue we had with the aluminum dryer vent duct and replaced it with hard pipe. We would highly recommend Mr Duct."

"We had five companies come out and look at our house and give us quotes for installing a Spacepak or Unico system in our house. Phoenix gave us the lowest quote (16k less than the highest quote!) and also had the best customer service. Everything was explained to us before, during, and after the installation. The owners seem to have a genuine passion for HVAC, which I wouldn't necessarily expect! Anthony was great with figuring out ways to get air to all the rooms in our 110 year old house with many quirks. Glad to have found this company."
