First real heat wave of the year hits, you turn on the AC, and the air coming out of the vents is room temperature. Or warm. Or the unit isn't running at all. Most of the time, an AC not blowing cold air is caused by one of six common issues. Some take less than two minutes to fix yourself. Others need a licensed technician. This guide walks through each cause in the order we recommend checking them, plus what to do if none of them solve the problem. Advantage Airtech ClimateCare has been keeping Durham homes cool since 1987. These are the fixes we see most often when a Pickering, Ajax, Whitby, or Oshawa homeowner calls about an AC that isn't doing its job.
