"Our A/C unit was giving us trouble and was the original unit from when the house was built along with the furnace. I called out 5 different companies to get quotes on replacing both A/C and the Furnace, Steve Bilica from Home Comfort Systems came out looked at what I had then came in and sat down with me and started to tell me about himself and his company which really made it more personal and made me feel more confident that I was hiring the right company for the job. Steve was up front and honest with me answered all my questions and gave me what I considered the best price out of all of the companies that came. Both Mike and Rich came out around 8:30 in the morning and were finished by 2 PM. Both Mike and Rich were very professional and respectful of our home, they laid down drop cloths to cover the stairs and on all carpet area's that they would be working which was very much appreciated. I highly recommend Home Comfort Systems Thanks Steve, I will be recommending him to everyone I know."

"Nothing but good things to say about American Family Heating and Cooling - highly recommended. Tim was friendly and professional on the phone, and quoted all charges up front. Nick came out and had a great combination of informal but professional demeanor. And no objection to me looking over his shoulder as he worked!"

"Outstanding service from beginning to end. The team arrived right on schedule, worked efficiently, and left everything spotless. Our heating system runs better, and the air feels much cleaner."

"On a Cold and Snowy 2nd day of Spring 2020, my heating system went out and got really cold in the house. Called Four Seasons to come out for an immediate repair. Four Seasons was able to come out within 2 hours. Technician was very knowledgeable and fixed the the problem right away and my furnace was up and running before the freezing night came. Thanks, Four Seasons!"

"As always, Mr. Duct kept in touch before hand, showed up absolutely on time, worked efficiently, and charged a very fair modest rate. The technician also noticed one or two things that we were trying to deal with (other than the furnace) and offered solutions with the equipment on hand. Saved us another call to another place! I'll have then back to clean the a/c and do our ducts (as they've done in past)"

"Thought it was a plumbing issue, but turned out to be an issue with air conditioner. They were prompt in responding to the emergency call. HVAC responder was knowledgeable. Price for furnace and AC was horribly overpriced!"

"On time, professional, and great customer support by Maggie. As far as value, they are definitely more expensive than some others we quoted, but you get what you pay for. We had our furnace and AC and water heater replaced by the Phoenix crew in Dec 19 and everything is still working well. Keep up the good work guys!"

"Don came out & fixed the issue with the gas leak coming out of the furnace within 15 minutes. He then helped with my Nest thermostat that reset & wasn't turning back on. He was very courteous & knowledgeable."

"This business is the company that bought the older Barrington Heating and Air Conditioning. I have relied on Barrington to service my house furnace and A/C for more than 50 years. They have come to my rescue more than once. My service technicians have become friends, not just repair people."
