We’re acutely aware of the health hazards mold infestations introduce to homes, families, and workplaces. Understandably, discovering mold growth on your furnace filter during routine maintenance can be very disconcerting.
This isn’t as uncommon as you might think. Just ask professionals like Dial One Johnson Plumbing, Cooling & Heating, a leader in heating and HVAC repair services in Balch Springs, TX. Based on this experience and expertise, the team shares some vital information below about what to do when you discover mold on furnace filters.
Immediate Actions To Take When You Find Furnace Filter Mold
If you see visible mold growth on your furnace filter, do this first.
Replace the Moldy Filter
Most importantly, start by carefully removing the filter. Rough handling will release mold spores into the air and your system’s components.
Wear gloves and a mask, and place the old filter into a sealed trash bag for disposal. Install a fresh, high-quality filter in its place.
Clean the Surrounding Area
As you are installing the new filter, be sure to clean the filter housing and cover carefully.
Wipe down these surfaces with a disinfectant solution to eliminate residual mold growth.
Inspect and Clean the Ducts
Mold spores can easily spread through your ductwork. A moldy filter is a strong warning sign that spores have infiltrated other parts of your HVAC system.
Clean exterior vents and schedule professional duct cleaning to remove contaminants. This attention to detail may prevent recurring or spreading mold growth.
The Causes of Mold Growth
These are the leading causes of mold on furnace filters.
High Humidity Levels
Excess humidity affects our Texas climate during almost every month of the year. Mold growth on filters is one side effect. Without a reliable HVAC system, overall poor indoor air quality can be another.
Leaks and Water Damage
Water leaks inject moisture into your ductwork and indoor areas. Regular professional HVAC and plumbing system maintenance could prevent these hazardous system leaks and, by extension, stop mold from taking hold.
Dirty or Clogged Filters
Old, dirty filters are more prone to trap moisture and contaminants as they clog up. If left for too long, this fosters mold growth and many other issues.
Poor Airflow
Dirty or damaged components lead to insufficient HVAC system airflow, too. Prevent excessive condensation, and you’ll equip your system to stop mold in its tracks.
The Dangers of Mold on Furnace Filters
During contaminants’ removal, it’s common for professionals to discover an active mold infestation on the furnace filter. Mold causes property damage, although the largest concern is its potential health risks like:
- Respiratory issues
- Allergic reactions
- Asthma attacks
Long-term mold exposure can contribute to problems with chronic conditions, so don’t wait to deal with them.
Preventative Measures for Mold on Furnace Filters
Has your HVAC system recently been professionally inspected and remedied? The best preventative steps to ensure mold and mildew prevention include:
Regular Filter Replacement
Check your HVAC system filter every 30 days for dirt, clogging, and mold growth. Change the filter when needed, but no less than every 90 days. High-quality filters more effectively trap mold, allergens, and other problematic airborne particles.
Control Indoor Humidity
Set a target of 50% or lower for indoor relative humidity levels. A modern humidifier/dehumidifier system could help you maintain healthy, comfortable living spaces.
Schedule Routine HVAC System Maintenance
Regular HVAC maintenance visits from a competent professional prevent mold-causing HVAC problems. Ordinary household cleaning can’t match these routine component cleanings and system tune-ups.
Duct Cleaning Services
Professional duct cleaning also effectively removes mold on furnace filters, including spores and other pollutants that often build up in these channels. This service will greatly improve your indoor air quality. Repairing damaged ducts also aids in energy efficiency.
When To Call an HVAC System Professional
While the basic cleaning and filter replacement discussed above are first-aid measures, mold infestation demands immediate expert intervention. An HVAC system professional can restore proper furnace function and protect your family’s indoor air quality.
