"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."

"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."

"Sal was a very nice guy and explained everything he was looking at and doing in detail, this w as during a very cold spell and we weren't able to heat the house efficiently much higher than 60 degrees F, They came out right away and was on time and i spent way less money than i anticipated, definitely would hire them again and highly recommend them. Sal was our technician and he was outstanding!"

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace.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."
