"It's hard to find good work nowadays, but this company provided it with my boiler combi installation. Dustin, and Eric answered all my technical questions in regards to my old boiler setup, and the installation crew completed the job professionally. I had 4 Hvac company estimates, and I settled with them because of Dustin's knowledge, and patience. I would definitely recommend this company to all my family, and friends."

"For over 20 years my wife and I used another A rated Angie’s List heating and air conditioning firm and we have given them good reviews in the past. Recently our 20+ year old heater started acting up. At times throughout the day or night the burner wouldn’t ignite and we would be without heat. After seven service calls and various parts at the cost of $700.00 our old service company could not repair the heater and the problem remained unresolved. So we decided to get estimates to replace our entire HVAC system mainly due to it’s age and this unsolved problem. Vaughan Heating and Air Conditioning was on our list of acceptable companies to speak with due to their Angie’s List A rating. We called Vaughan and they sent Tony Pellegrino to our home the next day. My wife and I were very impressed with Tony. He spent over an hour at our home scoping out our basement, configuring our new system and answering our questions. Later that day we received the Vaughan estimate that Tony sent by email. I called Tony and he spent another hour on the phone addressing my questions and concerns. We received the other competitor's estimates over the next two days. We accepted the Vaughan’s estimate which was $1,100.00 more then the lowest estimate and $2,500.00 less then the highest estimate we received. Our choice was based on our comfort level with Tony, the price of the job, the longevity of the company (established in 1937) and the quality of the heating and air conditioning units that Vaughan installs. We accepted the Vaughan estimate on Saturday evening and Tony scheduled our job that coming week on Tuesday (for the heater) and Thursday (for the air conditioner). The reason for the one day in between work was because they squeezed our job into an already full week of installations and we were really pleased that they did that for us. On Tuesday morning at 8:30am the installer’s, Marcus and Jeff were at our house ready to start the job. These guys were friendly, professional, extremely competent and also very neat and clean, covering our rugs, etc. Jeff and Marcus did and exceptional job installing our new HVAC system. It’s “state of the art”! My wife and I are extremely happy with the job Vaughan Heating & Air Conditioning did and we could not be more comfortable, then we are now, in our home. A great price, a great people and a great job! We highly recommend Vaughan Heating & Air Conditioning! Len & Lorraine Fedullo"

"I called the number. The person confirmed the appointment. The plumber was at the location at the precise time, inspected. Called me for the expected expense, we agreed over the phone. He got paid via Visa card and did the job. All done so professionally. Can't get better. I think he was little high in price but because its 5 degree F outside, its OK for one job."

"They scheduled a timely install for my water heater. They also do all my heating and cooling work. Highly recommend D'Amato Inc. Very professional and friendly."
