4 Reasons Why Your AC Smells Bad
Posted on June 30th, 2022 by Devine Bros
There are several reasons why your air conditioning system might start to smell bad, and it’s important to know what they are so you can fix the problem before it becomes chronic or even dangerous. The following guide will walk you through the most common causes of an HVAC unit that smells bad, as well as some methods you can use to quickly and easily fix these problems.
1. The Air Filter is Full
Full filters in your air conditioner aren’t just ugly — they’re a major smelly culprit. Filters should be changed at least every 90 days, but it’s a good idea to replace them twice a year if you live in an especially dusty area. If you haven’t changed your filters for more than six months, try doing so immediately, and then get back on a 90-day schedule from there.
2. Mold or Bacteria Are Growing in the Air Ducts
Mold and bacteria grow in moist environments, so it shouldn’t be surprising that mold and bacteria can both build up inside your air ducts. You should also ask your service company how often they recommend getting your ducts cleaned. From there, they’ll be able to take care of your ducts when needed.
3. Obstructions Are Blocking the Air Flow
One of your air vents might be obstructed! Blocked air flow will give off a musty odor and reduce your comfort level. If you’re finding it hard to breathe in an area of your home, check for any blockages in air ducts or vents.
If the problem persists after checking these two areas, then call a professional specializing in HVAC systems like our team here at Devine Bros.
4. Leaks in the Evaporator Coil
If you smell a rotten egg odor when running your air conditioner, it could be a sign of leaks in your evaporator coil. Leaks are especially prevalent on coils that haven’t been changed in 10 or more years. If that’s your situation, contact us at Devine Bros today!
