Is Mold Hiding In Your HVAC System?

HVAC Systems and Mold

Mold is a common problem in home HVAC equipment. While it’s typical for mold to develop in HVAC units over time, letting the mold grow unattended may decrease air quality and lead to some breathing issues for those living in the home. Homeowners need to find out about typical sources of HVAC mold and learn how to remove mold from their systems when needed. 

Common Sources of HVAC System Mold

Air conditioning systems in particular tend to harbor mold as a result of normal use. Drain pans, which often hold standing water for long periods of time, are primary mold sources. Since pipes contain bends and curves that may hold onto water from unit operation, they can also harbor mold. Often when there is mold growing inside the unit, you may be able to see mold growing on the inside of the air ducts.

Understanding the Problem

While the visible mold can be easy to spot, simply removing it will not fix the problem with your HVAC unit. It’s important to treat not just the mold itself, but the source of the problem to prevent mold from reoccurring in the future. To try to find the cause of excess moisture in your system, look for water leaks and flaws in your unit. Once you’ve located the actual problem, it may be time to call in a professional to help repair or clean your system.

A Lack of Federal Guidance

Even though HVAC mold contamination is a common issue for homeowners, there is little to no federal oversight in this area. This lack of regulation makes it possible for any repair service to claim that it is qualified to perform mold remediation in homes. While some of these cleaning services may be experienced in removing mold from HVAC systems, others may not be qualified at all. If you use a regular HVAC technician to service your unit, ask him or her for recommendations if you suspect mold.

HVAC Systems: A Closer Look

The interior parts of your HVAC system are ideal places for mold to grow. To avoid dealing with this issue, examine your condensate drain regularly for clogs. If this drain gets backed up, the standing water can develop bacteria, which may turn into mold. Once you’ve removed the mold from the system, you’ll need to make sure it doesn’t return by regularly maintaining the unit to keep the ducts clean.
