Called Enercare because we assumed they would help us to the best of our ability with our air conditioner problems. Phone customer care was helpful, but when the technician came out, he took a quick look at our system, without diagnosing anything - and basically told us that he couldn't service it and that he would now charge us $99 + tax for basically doing nothing. We would now have to pay extra fees and work to get a crew out to do the work.
Was on the phone with a supervisor after, and she proved very unhelpful and not at all caring about the situation.
Do not use them under any circumstances. You are better calling your neighbourhood HVAC specialist to help you out any day.
