Best Heating & Air Conditioning / HVAC In Willow Grove

“Couldn’t be happier with the experience we had using Hirschberg!! We had found a gas leak and they came right out! John was our technician and he was so friendly, knowledgeable and a pleasure to work with! He explained everything he was doing and why. After the Gas leak was fixed, our water heater went and they came right back out and fixed that too! Highly recommend John!“

“1st Tech was on time & confirmed our initial diagnosis. Part was ordered and repair expediently completed the following day by Rick who was courteous, professional & very thorough. The office staff was also phenomenal with consistent updates. Exceptional overall experience! Highly recommended,“

“Mickey our serviceman was excellent. I had a problem with my sink and he assessed all areas and came up with a solution. He was so polite, took off his shoes when entering my house, and was a real gentleman. He communicated so well. He was so informative and knowledgeable. I want to note that one thing really important to me is when a company answers the phone when I call. There was such a nice woman who answered my call to Cooper each and every time I called. She was so nice!!! She really sets the tone for this company. It was so nice to talk to such a sweet and helpful person.“

“The service was excellent ! Workers arrived on time and explained what they were doing in the process of repairing my chimney. Office staff responded in timely manner with estimate and correspondence. I highly recommend this company! Thank you Gannon family and staff!“

“These guys were top notch!

I had to get a drain pan replaced but there was more work than expected. Had to take the refrigerant out and the whole 9 yards because the pipes were in the way of the A-Coil.

However, they did a fantastic job. Erich is full of knowledge, cares about his quality of work and all of it shows. His assistant also was polite and knowledgeable, great guys!

There are a lot of choices out there when it comes to HVAC companies and it’s nerve wracking finding the right one, but Rossi Mechanical Services will treat you right.“

“Very pleased to say we had an outstanding experience with our technician Rob yesterday. We had a minor problem with our air conditioning system and Rob diagnosed the immediately and fixed the problem quickly. In a world where customer service has died, we couldn't have been serviced any better.“

“DMES installed a new energy efficient HVAC system at my house a few winters ago. The freezing cold of winter is a horrible time to have your HVAC system die. They responded quickly to my emergency, installed a more energy efficient system than what I had, and were so professional. They continue to impress me in how quickly they respond each time I need routine service. I have them on speed dial for all mechanical and electrical projects at my house and I highly recommend them to my neighbors and friends.“
