As the weather warms, more and more of your customers will be switching over their HVAC control
settings to Max A/C. And if the system doesn’t respond by blowing that refreshing cool air, they will show up at
your door to find out why. When faced with a "not cold" A/C complaint, the first thing I do is
verify the complaint. If the interior checks pass, but the air exiting the ducts is too warm, the next step is to
pop the hood and see if the compressor is engaged.
