Best Heating & Air Conditioning / HVAC In Norristown

“Very professional and work performed is great. I would highly recommend this company if you want something done right. My only issue is price. The price of service is very expensive.“

“We had our furnace replaced and a new air conditioning system installed, and the entire experience was excellent. Their quote was very competitive compared to others we received, making the decision an easy one. The team was quick, efficient, and professional from start to finish. Everyone was friendly, courteous, and took the time to answer our questions. The installation went smoothly, and they left everything clean when the job was done. We really appreciate their quality work, fair pricing, and outstanding customer service. I would highly recommend them to anyone looking for reliable HVAC services.“

“You go with the local company when they have great reviews, and Davis has them.

Even so, I was surprised by the outstanding quality of their service. My aunt (90 y.o.) wanted to have a dual split system in her older home. Their quote was more than fair, and came in under others.

They scheduled us within a week (it was installed in December) and the service was outstanding. Chan and Julian were gentlemen, and were very considerate of my aunt and her home.

While we haven’t used the cooling yet, the equipment that they installed looks great, and the outside looks great too.

My aunt and I are very happy with their service.“

“Great place and honest service. I would recommend them. At first, I thought their prices were expensive, but after giving them another chance, I found the pricing to be reasonable.“

“Had a water heater break overnight and DiRosato was there same day to replace. Gentleman who answered the phone was able to move some things around to have a tech come out in an emergency/. Great service and great installation“

“We use this vendor often, and they are always on point! Extremely reliable, transparent, and easy to work with. They carry a wide variety of parts, and if there’s ever something you can’t find, they’ll go the extra mile to track it down for you. I’ve never had any issues with their service. Rebecca is our rep and she’s absolutely amazing — shout out to her for always being responsive and helpful! Highly recommend this team.“

“We purchase our water softener and filtration equipment through Duff and install it for our customers homes. The products have been great and their team is always easy to work with. We’ve had a great experience working with Duff and appreciate the partnership!“
