"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"My home air conditioning wasn't functioning properly. Will Stahl analyzed the problem and had a replacement unit installed in less than 24 hours on the hottest day of the year! You cannot get better or more reliable service that Stahl's Mechanical! And great conversation too!"

They are really good. I had four guys out here for, like three days. They put in a great heat pump real easily. Not only did they put in a new furnace, but the ducting that was in here at the house was, like, 30 years old so they tore it out and re-did it with custom ducting made out of big sheets of metal. They only charged me $3,000 for the furnace. I am glad I did because it has made a huge difference in the air quality here. They came out yesterday. They said they would be back for the winter servicing. I have an oil backup so they were out for a number of hours yesterday. They will service it for the next 10 years and it is under warranty for 10 years too. They are great guys. Frank Ford is the owner of it. He and his guys do excellent work and really care. Their prices are as good as anybody. The price depends on what unit you get so it is hard to say. These guys are terrific. I would say if you needed a new heat pump or furnace they should be number one on your list.

"I had a great experience with this HVAC company from start to finish. They were professional, punctual, and took the time to explain everything clearly. The technicians were knowledgeable, respectful of my home, and made sure the job was done right. Their pricing was fair, and the quality of their work exceeded my expectations. I highly recommend them to anyone looking for reliable and honest HVAC service. I will definitely be using them again in the future!"
