"as the only firm that creatively approached solving my problem. They found an affordable approach that met my needs without any preconditions. The only downside was that some of the equipment they installed were deffective at the time of installation. This may be the fault of their supplier, however."

"There were several problems with the space pack AC unit AC Engineers installed in 2016. AC engineers really stands behind their work. Their technicians are excellent. It took several visits to restore my system but AC Engineers did the job right. I live in a 100 year old house and repairs to my boiler and AC and other systems are a fact of life. AC engineers is a pleasure to work with and I have no reservations to recommend them to a friend."
