We've been using Aire One for our regular HVAC needs for 9 years, and we've always been pleased. They installed a gas line for a natural gas BBQ at our first home, so we called them when we moved and needed a gas line put in at our new home. We has a service call for HVAC tuneup at the new house and to have the gas line done. We were surprised then, when the service tech told us we had to call the head office to get a quote for the BBQ line -- that's exactly what we asked for when we booked the appointment in the first place. So, we called back and were surprised to hear they couldn't book us until over a month away. We reluctantly agreed to wait them out, as the quote was reasonable and we knew the summer was a busy time for them. Then, the day before the appointment, we got a call from the head office asking us to confirm the nature of the work as it had been "entered wrong" in the computer system, and then got a second call later that same day (less than 24 hours before the appointment) saying they couldn't honour the appointment because the installer assigned to the job didn't have the parts required. They wanted to reschedule for the week after, which was significantly inconvenient for us. They weren't ready for an appointment that had been on the books for over a month and they wanted us to accommodate them. Then they dropped the bomb that they'd be charging 3 times the original quote. A $250 job suddenly became a $750 job! When I asked why, they said the job would require 2 people instead of 1 and would take all day -- which didn't in any way explain why they'd given a much lower (and more reasonable) quote a month earlier, or what details they had now that they didn't have earlier in order to give that quote. I asked to speak to the manager and was told he was gone for the day. So I asked them to have the manager call me first thing in the morning. He did not. When I called back the day before the rescheduled appointment to ask why the manager hadn't called me back, they only seemed interested in knowing whether I'd be keeping the appointment or not. No mention of the manager speaking to us at all. Needless to say, Aire One has lost years worth of future HVAC servicing work from us and we won't be recommending them.
