Gerry was recommended by Brent at Shift Air (also great reviews). He was quite busy and I had to book a month ahead. When the scheduled day came it was -30 and a blizzard, so Gerry phone us on a Sunday and rebooked for later in the week. He showed up on time, did a good job, and even pressure washed the heat and return vents. The wife was very impressed with their work as she was home at the time. His bill was lower than his quote, which says alot about his honesty. I will be rebooking in 5 years time
