"Home Comfort Systems was professional, honest and fairly priced. Steve Bilica (owner) came out to give me an estimate on a new furnace. He made me feel comfortable, which is important to me as a single woman. His estimate was the lowest of three I obtained ($4150) and he was so honest, he advised that my current unit didn’t need replacing yet. (The only reason I was getting estimates was because some other cut-throat company told me I needed a new one...for $11k!!...due to a cracked heat exchanger. However, all the other companies I contacted for estimates said I did NOT have a cracked heat exchanger.) I decided not to get a new furnace in the end. It’s been running great, although I did need a new blower motor about five months after the estimate, so Jeff D installed it for me ($385). Way cheaper than a whole new unit, so I’m happy. I’ll definitely go with this company again for repairs and when it’s time for a new furnace."

"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!"

"Adam shared valuable information with me about the maintenance of my existing furnace."

"Tech came on time. Checked furnace and humidifier."

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace. After speaking with a Four Seasons sales rep, we knew they were the best choice to go with due to their thorough assessment, knowledge of products, availability of service and overall transparency. And perhaps most importantly, they were not pushy and respect our decisions on what system we felt was best for our home. As with any expenditure of this nature, there will be some ironing out of details and inevitable bumps to get everything completed, but the overall experience amounted to an energy-efficient HVAC system that was installed with care and expediency. Their service technicians are also friendly, thorough, knowledgeable, and available at a moment's notice. We are so glad that we went with Four Seasons."

"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."
