"Shawn called to arrange the appointment promptly.  On the day of service, he and his employee arrived promptly and professionally.  Very polite and courteous.  He pointed out a part that needed some attention and that if it was cleaned properly, it wouldn't need to be replaced....saving me money!  I would definitely recommend and use Porter HVAC services again.

"The technician did a very good job cleaning the hvac ducts."

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

Was able to get same week installation. Both Jorge’s & Jacob’s crews worked well together in same space. They were all responsible, respectful and explained post installation. Referred by my family, past customers."

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward.
