I am extremely satisfied with Heat Engineering. They installed a new A/C unit and they did a great job. Brian Papania informed me of everything I needed. He was very helpful. Stanley was the main installer. He was thorough, courteous and did not rush the install. It was obvious he was experienced. The whole procedure was smooth. Service: Install AC

I called very early this morning for emergency service. It's 87 degrees in our home. My husband just came home from the hospital. He's not doing well with the heat. Called 3 times. Finally, told they could come between 12 and 3. This is a life threatening situation and they are callous to it. Have been waiting 2 1/2 years for sales person to get back to me regarding an 80 gallon hot water heater. Luckily, I called ABT the next day after he was so wishy washy.

I had it in 12 hours. I've had this company for the 48 years that we've lived here. They were wonderful, but within the past 10 years, that is no longer the case. This will be the last time I do business with them. And now, only because I just paid over $500 for a service contract. Supposed to get you preferential treatment. If they threat a long loyal customer this way, what do they do to the new ones?

Service was very professional. My 20 yr old furnace lost connection with heaters. One heater was reconnected, but a part had to be located and installed the next day. There was no extra visit charge.
