Have you sniffed out this problem? Instead of cool, fresh air flowing from your Vacaville CA home air conditioning, a foul, unpleasant odor blows in. Smells detected when the AC is first turned on have become a common complaint. When your air conditioner smells musty, an AC contractor can help to diagnose the source of these odors.
What’s causing the bad smell from my AC?
The source behind the smell is typically dirt, dust and moisture that has accumulated on the AC unit’s evaporator coil. This buildup creates the perfect environment for bacteria. While this issue is most common when the AC is first started up in spring, it can occur any time of the year. You might also notice this unpleasant smell in the fall if you have a heat pump.
