We had A1 install a gas furnace, AC, and a gas water heater (replacing a rental unit). TL;DR, we are very happy with the service and hardware we received, and would like to especially call-out the skill, professionalism, and thoroughness of our sales rep, Andrew, and the install team, Brad and Deron.
Andrew took the time to review various aspects, such as personal preferences, and hardware and installation options. He identified possible issues (i.e., regarding a finished basement with limited venting options and an old electrical panel), and solutions to those issues. He made detailed notes, and took photos and videos to share with the install crew (more on this later).
A1 has an online portal for presenting and reviewing proposals, and this made it very easy to review and compare options and specifications.
On installation day, Brad and Deron literally rolled out the red carpet for us -- a thick (red) tarp to protect our floors. They arrived around 8:30am, and were finished by 4:30. They had reviewed Andrew's notes, photos, and videos, so they were prepared and got started immediately. There were no unpleasant surprises. They were polite, respectful, happy, neat, and tidy.
They replaced the water heater first, so we would have hot water as soon as possible. We didn't even have to ask! They even took care of returning the rental tank to the company, saving us a $75 pick-up fee. It was these courtesies and considerations that really stood out. Brad also relocated the electrical shutoff switch for the furnace and blower, so that it was more easily accessible for my elderly parents. Again, we didn't have to ask, and this was a very welcomed change.
The install ended with the install team showing us the features of our new systems, and how they worked. The team's work was excellent, and they were deservedly very proud of it. We highly recommend the professionals at A1.
