Amanda P did an excellent job. The furnace fan has been noisy since the day we moved in. And for years we've had the annual check-up and no one was able to stop the noise at least until Amanda came in. She figured out what the problem was and quickly fixed in. Coming this spring when we have our ac unit checked , we will be requesting to have Amanda P assigned.

Juan C. and his coworker installed my new air conditioner today. They did a great job, were very knowledgeable and very respectful to me and my property. It was a pleasure having them at the house today. Good job and very satisfied.

I was able to get an emergency appointment which the representative fit me in at this busy time of the season. Shane P arrived within the window and explained everything he was doing and thoroughly explained his findings. I received invoice and diagnosis right away via email messaging. I also had a visit from Bryan who took his time evaluating my furnace and water heater. He sat down and explained options in replacing both systems. He also was honest in offering me options. No pressure selling and having me sign a contract. His side conversations also took a stressful situation and made it more calming. Thank you to all !.
