"The replacement of my a/c ( with indoor coil) and furnace was handled in an extremely professional way. Holtzople Heating and AC helped me to find the best replacement units for my 20 year old Trane system. I am impressed with the knowledge of the sales person sent to provide quotes. I am also impressed by the skill and meticulous care that the installers took while replacing my entire heating and cooling system. Within a day, they took out my old system, installed the new system up to factory specs, tested and made sure all phases of heating and cooling were functioning as they should, and cleaned up, taking away all of the old unit, leaving nothing behind. The last thing the head installer told me was that a quality control team would be in touch and be coming in within the next two weeks to make sure everything was continuing to operate as it should. This attention to detail, and customer satisfaction is what has impressed me the most about Holtzople Hearing and A/C."

"Everyone from Presidential has been friendly and helpful -- great customer service! Glenn came to our home to discuss options to replace our furnace (fuel oil) and AC systems with a heat pump. He immediately understood that we were looking for a heat pump eligible for the new tax credits (unlike another company, who only provided estimates on what they had in stock). He prepared the estimates for 3 different models on site, and he noted that the heat pump eligible for the tax credit would cost about the same as an older model (unlike what the first company told us). We were able to schedule installation quickly, and then the adventures began. Harvey and Andre were here for 12+ hours...because a wire was either never connected at the factory or came loose during shipping. We also had to replace a defective line from our house to the unit. While it was a complicated install (not the fault of Presidential), we rec'd great service from hardworking staff members. Highly recommend!"

"Kamal diagnosed and completely repaired a failure with our upstairs ac/heat pump that was having high/low stage lockouts. Neither the ac or heat pump was working. He replaced the compressor which had died, replaced the TX valve in the attic, which was installed incorrectly by the original installer, flushed the line and checked for leaks, etc. In a quick turnaround time. Kamal communicated every step of his repair and was very honest and responsive. Everything is now working perfectly. This is a complicated system to repair, and the expertise, timeliness and the VERY fair price Kamal gave to us made it a First Class job. Great work!"

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"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 whole house could hear the vibration when our two year old Tran xv20i heat pump was at 67% work load. It seems the issue started from day one it was installed. Tried to reach out the installer but they went under. In June, I called McCrea. Mark Dzbynski came over, carefully checked everything and then concluded that refrigerant was not charged to the correct capacity. He explained that our system line is longer than usually and additional refrigerant is needed to compensate the length. He carefully calculated and addded the correct amount based on the temperate & length. From June and Oct, the vigration never came back. No one can tell when the system is on because it works so quietly. I really appraicate the work done by Mark and his work ethinics. Very pleased!"

"Carlos, Yarel, Muhammad and Conrad did a great job installing my new Heat Pump. They arrived promptly and did a thorough, professional, and efficient job. I highly recommend their services to anyone."

"The technician was great. He explained what he was doing as he went along even though it was freezing outside. Checked my entire heating system to find the problem and replaced only the parts that were broken. Got my system back up and running in a little under two hours and was very pleasant and understanding when we asked him many questions and answered everyone so that we understood him. Thank you so much for your professional manner and courteousness. Got my hearing system to stop running in emergency mode and back to normal heat. Thanks"

"Unlike other vendors, Adam was straightforward and provided honest assessment without complications and excuses, which initially made me suspected if he was for real. Fortunately I selected Weather Masters for their professional installation of 3 heating/cooling systems. I'd recommend them to any other customers."

"I recently had SPECS Heating & Cooling install an AprilAire humidifier for me, and I couldn't be happier with the results. From start to finish, their service was exceptional. The team was professional, knowledgeable, and efficient, ensuring that the installation process went smoothly. Since having the humidifier installed, my indoor air quality has significantly improved, and I've noticed a positive difference in the comfort of my home. I highly recommend SPECS Heating & Cooling for their top-notch service and expertise in HVAC solutions. Five stars all around!"
