We have decided to install a humidifier on our furnace and an air purification system. Some of the companies we called gave us quotes and details on the phone, Abbey Air said they needed to schedule an in-home visit to better evaluate what option suits best. (That sounded like a sales pitch but OK, we want to do this right). Our appointment was for yesterday between 11:00 and 2:00 pm. They did not come, they did not call. I waited 24 hours before writing this review to give them time to get in touch with us and explain why they did not respect an appointment at which they were (potentially) going to sell me more than $1,000 worth of equipment and installation, but no, nothing. I would definitely avoid them for service if they bungle even sales calls.
