Get matched with top air conditioning pros in Sharon Hill, PA

"Frank and his team of workers are a wonderful team. They installed our new heating and air conditioning units. We would recommed them over and over again. So thankful, to have found them!!!!"

"Everyone At Generation 3 including Bill, Mike, and Lisa was nice and professional. They were easy to get in touch with and were prompt with appointments. I liked that info about the person coming to your house for the appointment would be emailed to you the day before and they would call prior to the appointment to let you know that they were on the way I had the electric in my house upgraded and an electric car charger placed outside of my house. The electric now has a dedicated 240V line running to the car charger outside for fast charging. Everything is well labeled and in great working condition. The electric car charger was placed on a sturdy wooden post and painted in a glossy black to match the trim on my house. The post is very nice and tasteful. My neighbors approve also and that is important. I will definitely use them again!

"Very thorough but offered to sell me a new air conditioner which I didn't need"

"Dave did a great job, he explained what caused our Heat pump to stop working. We bought this unit last June 2019 . So we were very upset when the unit stopped working, it was so hot and Dave had to go up into our attic / crawl space. That was super hot, but he was able to find the problem and get our unit to work. We are very thankful for having Dave as our technician. Thank you Dave and Rohrer's One Hour Heating and Air Conditioning. We have been with them for 35 years."

"Got them to help my mother install a A/C unit very professional and clean work they did, will definitely be hiring again for central air in my new home I canâ t wait , thanks Alex!"

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Did not return basement ceiling to original condition."

"The engineers overrided the recommendation of the salesman and initially installed a furnace Is with a much higher BTU rating than my small place required resulting in excessively dry air which for me, was a health risk. After I complained they somewhat reluctantly replaced it with an appropriate furnace. The sales representative did strive to do what it took to satisfy me which I Greatly appreciate. And the technicians and installers were and installers were very good."

"My heater broke and was in desperate need of service. Not only did the come out the work was done perfectly. Highly recommend"
