"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"

"I have used them for two different jobs and they were excellent both times. They have serviced my system several times as well. I would highly recommend them and I will definitely use them again."

"

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.

"Dan and his Dylan were phenomenal. I contacted Dan a few weeks ago when I noticed the blower fan on one outdoor AC unit was not working. Dan was booked out for a few weeks for regular maintenance service calls (and now I can I understand why he's in high demand). I did not need urgent service since the weather was fair and I had another AC unit to hold us over. Dan was able to special order a new motor ahead of our appointment and bring it with him. Besides being very friendly, and of course, punctual and professional, he was very easy to work with when discussing overall HVAC concerns in my home that we recently moved into. After repairing the fan motor for a great price, they also did an above-and-beyond cleaning+fixups on the indoor and outdoor units. Needless to say, I'm VERY happy with their service and will have them back in the fall for winter readiness and potentially to rework some ducts (my idea, not his)....and I hope for many years to come! Thanks guys!"

"Fantastic. The scheduled for a 30 minute window, called an hour in advance to give approximate arrival time. Completed the work quickly and made sure I understood exactly what work was needed. Would highly recommend these guys over any of the other contractors in the area."

"It went extremely well. Because of the expected large investment that I needed to make to replace both units, I went out for competitive bid with two other firms, both of which were reputable but larger, corporate-based firms here in southeastern Pennsylvania. (They advertise everywhere.) One of these firms was the incumbent with whom I had done business with for 23 years on both units with an annual maintenance agreement. Harmon HVAC came back with the best proposal, best price, and addressed my needs. Each of the other two firms tried to "up sell me" to include "bells and whistles" that I specifically did not want. The incumbent's price was also over $10,000 more than Harmon HVAC's bid... so much for being a loyal customer. After selecting Harmon HVAC, the installation took 3 days and was world-class. As a mechanical engineer, I pay special attention to the details and their work was some of the best work that I've ever seen in my 25+ year career in high tech engineering environments. Every aspect of working with Harmon HVAC is wonderful, from the friendly Office Manager (Mrs. Harmon) to working directly with the owner (Bruce Harmon) and his team."
