"We are beyond happy with the work and professionalism of Porterhouse Cooling and Heating. I called for an estimate and they were out the next day. Then that same day they were able to get us set up for our work. They began the project only a day later. They truly were amazing to work with and supported us throughout the process. We needed a huge job done, because we switched from all electrical to adding gas to our house along with a furnace, water heater, air conditioner, and all new ductwork. We had multiple obstacles that most people did not want to take on. Porterhouse helped us come up with solutions and were very reasonable. They were extremely hard working and did a great job with our house. We love our new heating and air systems! We also have a new thermostat that is wonderful. I highly recommend them for any heating or cooling needs!"

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace.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

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."
