Philadelphia, PA: March 2019

"I want to say how impressed I am with the quality of your workmanship. I came home last week and was finally able to see the project, the work is really admirable."

Newtown Square, PA: December 2018

"We added dampers in the large ducts to control the volume of air flowing to the living area versus the volume flowing to the bedroom. That allows us to better control the bedroom temperature, especially at night. If you need someone to do the work, I recommend Regnier & Associates, a small family company in Newtown Square that has been in business for decades. They do electrical work, including generators, and HVAC work. We also have them do our annual service on the furnaces, AC condensers, and generator."

"When our central air broke down, we felt doomed. You hear so much about people taking advantage of you. I contacted Rich Regnier and got an estimate. We wanted to get heat at the same time, and Rich thoughtfully went through all the options, pointing out costs and efficiency. We settled on an outdoor AC with a propane furnace. Everything worked great, and the cost was affordable... I highly recommend Regnier & Assoc."
