"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."

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"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace.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

"Professional , timely analysis of the problem and expert installation of a new A/C system. We were pleased with the price and outcome. We plan on using United Heating and A/C for a new furnace in the near future."

"The best thing about this company was the communication via text and email. We also liked that they gave us a two hour window of time for the appointment rather than a four hour window. On the downside the service appointment went too quickly. The technician took the vacuum down to the furnace, but according to the main office our furnace only needed to be wiped out. We have lived in our hime for 20 years, and I believe that every time we had a maintenace check and cleaning by other companies the technician vacuumed the furnace. Also the technician arrived in a van with a different company name than the one we had called for the appointment. When we called the office we were told that it was indeed their van: they also own that company. But they failed to tell us this in advance."
