"Tom was terrific....repaired boiler....cost reasonable.....explained everything so clearly so that even this 88year old understood it....experience with company from start to finish was a pleasure"

"Mark and his crew were quick to send an estimate + great communicators (always a text or call when they are on their way - that means a lot to me). They worked hard, explained questions we had, tested and cleaned up. We still have to decide on some add-on services that seem a bit expensive (also in comparison to the rest of the job). But they have our trust + we hope to stay with them)."

"The plumber who came was fantastic! Very professional and efficient. The price was reasonable, too. I would definitely recommend them!"

"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"

"The guys Immediately understood the problem and part necessary to replace. They Returned the following day with the part and replaced it quickly. They also helped me understand the problem and made sure the thermostat was working. Very friendly and pleasant team."

"Chris was great. He gave an estimated arrival time and kept me posted about when he would arrive. Once he arrived, he was very professional and respectful of my home; he didn't even mind my nosy cat. He gave me an assessment of possible repairs needed on my portable AC, gave me an estimate for possible costs and provided an invoice on the spot. He made the whole process very easy, and I appreciate the time he took to explain everything. I would definitely hire DG HVAC & Home Services again for my appliance repair."
