Services
Cornerstone HVAC LLC is a trusted service provider for the heating and air conditioning needs for Chester, Delaware and Montgomery counties of Southeast Pennsylvania and surrounding areas. We service all makes and models of residential heating and air conditioning equipment. We can install equipment from many manufacturers but there are two brands that we promote most.
There are two halves to your ac system. Half is outside and half is inside sitting above your furnace. It works by absorbing heat at the indoor half which is carried outside thru the copper tubing and dumping it there. If you have ever held your hand over the outdoor unit and felt the heat blowing out the top, that is the heat that use to be inside your house.

Cornerstone HVAC was recommended by a friend so we used them. The owner Scott and his son Jordan we’re excellent. They came out within the hour of calling, diagnosed and temporarily fixed the issue so we could use the heater until the part comes in. He charges a fair price and is a no BS kind of guy. He also showed me the in’s and out’s of the unit as well as the home humidifier and showed me how to troubleshoot in the future. I would absolutely recommend them for any HVAC work.

It is Sunday and I was checking reviews for HVAC service. I had five companies and slowly whittled them down until I was left with Cornerstone HVAC LLC. I filled out the online forms and gave them the make, model and serial numbers. I expected a response on Monday. No, no, no that's not how they operate. I received an email approximately fifteen minutes later. They explained that the heater that we have would be not as familiar to them and recommended another company who, by the way, answered my call and they assured me that they will be here tomorrow at 8am. Now, that's service.

Scott responded to my call immediately. My furnace needed a new part, however because it was old & not efficient, I asked Scott for information on replacing the furnace & A/C. His pricing was very good & he educated me regarding my options without ever trying to sell me. I decided to replace everything & I added an air scrubber. I'm very happy with Scott's service & professionalism. I highly recommend Cornerstone HVAC!

Scott retrofitted our bilevel home with AC last spring. It was not an easy job, since we had hot water heat. Everything about working with Scott was a pleasure. He did a superb job. Our AC kept our home cool and comfortable all summer, and was quiet and efficient. He and his assistant were very considerate workmen, on time, and cleaned up everything. His price was extremely competitive as well. We would highly recommend him!!

Great company! Got Scott's number from a good friend who spoke very highly of their work. Scott came out the same day on a saturday when i called him to help fix my poorly designed current HVAC and also add a system to a new room I just installed. He proposed several great ideas to solve my issue and I ended up going with a dual split system that would cool/heat my new office as well as my entire upstairs. Installed system professionally in just over one day and at an incredibly reasonable price compared to others. Wife was worried about the aesthetics so Scott and Jordan got creative and you can

Scott and his son went above and beyond to make the install an easy experience. The install was aesthetically pleasing and they left the area cleaner than when started. I will definitely use them in the future and recommend them for all your HVAC needs.

Scott was outstanding to deal with. We had to replace our heating and air conditioning systems as well as our hot water heater. He took the time to explain our options and had very reasonable pricing. The installation of our systems were done flawlessly and we have peace of mind. Scott went over and above to ensure that we were satisfied. We highly recommend Cornerstone HVAC/Scott Shaw as he is honest, trustworthy and has integrity. We will definitely use Scott again and for our maintenance service needs in the future.
