"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."

"Nathan was our technician and he was great. He did a thourough job while being sure to explain what he was doing and why he was doing it so that I would be able to better care for the system in between services. He arrived exactly when he was supposed to and was done in a very reasonable amount of time."

"My overall experience with Porterhouse Heating & Cooling was very good. I called and requested same-day service due to a gas leak. Porterhouse Heating & Cooling came out that day, replaced the shut-off ball valve, and tested the system after the repair was complete. Also Porterhouse Heating & Cooling ensured the tankless water heater was operable since gas to the house had been shut-off due to the gas leak. Additionally, I had them to conduct my annual preventative maintenance on both furnaces. This was my third (3rd) time using Porterhouse Heating & Cooling. I find them to be responsive, knowledgeable, and customer-focused."

"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."

"Great. I talked with them while they were at costco. They gave us an estimate, got a great discount through costco and a free digital thermostat pad for the wall. Great unit and the installers were very professional, cordial and did the job quick. I would recommend this company to anyone who's interested in having a new furnace and/or AC put in."

"My furnace was making a lot of noise and I had a company come out to dagnose and quote on it.  They quoted me over 800 to replace the fan, motor assembly, and a capacitor.  I felt that was a little high so I had put the prices on Angies List to have some quotes for comparison.  TR millers quote cam back around500 so I scheduled the work. Upon arrival they checked the furnace and determined the only thing I needed was a fan and charged me 36. for the fan and 95 for the call.
What a breath of fresh air to have someone honest come work on your house.

"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."

"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."
