Air Conditioning and Mold: What You Need to Know
I hope you’re getting outside to enjoy nature and fresh air whenever possible! But let’s be honest, in many places as we move into towards summer, it’s hot and humid, and sometimes the best place to be is inside with the air conditioning running.
That brings me to today’s topic: mold in air conditioning systems.
Mold is very common in AC systems, whether you have mini splits or conventional air conditioning. But here’s the critical point many people miss: the mold in your AC is often a symptom of mold somewhere else in your building, not the root cause.
Your air conditioning recirculates the air that’s already in your space. If there are mold spores in the attic, foundation, walls, or around windows, your AC system is just moving that air around. The mold will end up wherever the air goes, but that doesn’t mean the AC is where the problem started.
In this video I’m talking about:
- How to maintain your AC system to prevent mold growth
- Filter replacement guidelines and why they matter
- Ideal humidity levels to target (and what’s a red flag)
- The importance of checking condensate drains for leaks
- When and how to have your system serviced
- Duct cleaning recommendations and frequency
- How condensation in AC systems relates to broader moisture issues
Watch the full video for my practical tips on keeping your AC system—and your indoor air—as healthy as possible this summer.
Another Tip for locating moisture issues:👉 Monitor your indoor humidity levels with inexpensive monitors from the hardware store, keep your filters clean, and aim for 30-40% humidity. Anything consistently above 50-55% is a red flag that something needs attention.
