"I was dealing with another company and called Holtzople for a 2nd opinion. From my very first phone call to the final installation I was very pleased with the service and response time. Not only did they send someone out the same day, they did not charge for the 2nd opinion and gave me thorough explanation as to what was going on. They were also very timely in getting me set up for the installation of my new AC. I couldn't be more pleased with this company and I tell everyone I know about them. Pam F."

"Went well. It was determined that the initial installation did not include the thermostat controller and that had to be rectified. Seems to be working well now."

"In researching the installation of a brand new central air system I got four bids. Dean's Heating & Air Conditioning saved us from the over-charging, poorer quality large commercial options - which there are too many of. Michael Dean is a conscientious, experienced craftsman who takes pride in his work, joy in figuring out challenging jobs, and backs up his work with a personal guarantee that means something when your name is on the business. The team did a full design and installation of a two-zone, 6-ton Trane central air conditioning system without taking up an inch of our living space. Amazing! One large company didn't even want to bid on the job when they learned that our historic 1920 Dutch Colonial home had no existing ductwork. Michael and his team took on the challenge, finding space in the walls, attic, and basement that I didn't even know we could use. We couldn't be happier with the result: perfectly cut openings for the vents and returns, beautiful ductwork, and a personal guarantee that I believe in. I couldn't recommend Dean's more highly."

"Doug did a phenomenal job! Very professional and courteous staff. Not too many places these days that you feel go above and beyond to provide good service - these guys are definitely like that. We work during the week and were unable to be present during installation, or later, when the work needed to be inspected. <br /> They accommodated our schedule by sending someone out to the house to be present during the inspection. They charged a small fee, but to us, it was worth not having to take a day off from work. We were extremely happy that they accommodated our needs, and they really did not a great job. Would definitely recommend! <br />"

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."

"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"
