Mold and mildew can cause serious damage to your heating and cooling systems that might require HVAC repair. Not to mention each time the AC or furnace is turned on, hundreds of thousands of mold particles blow out of the air ducts and circulate through the air inside your home. When inhaled, these particles can lead to many health problems including coughing, sneezing, shortness of breath, pneumonia, and more.
Dealing with Mold and Mildew in Your HVAC System
Below are tips to get rid of mold and mildew in your system for good.
1. Select a cleaning solution.
Finding a good mold removal solution is key if you are cleaning your HVAC system. If you want to go DIY, there are many options out there including household detergent, borax, baking soda, bleach, and so on. For those who don’t mind spending a few extra dollars, there are many commercial mold removal products you can choose from to buy.
2. Wear protective gear when cleaning.
You’re not only protecting yourself from the mold but also from the chemical and cleaners. When cleaning your HVAC system and removing mold, EPA recommends using an N95 mask for protection. Other items you need are protective eyewear, coveralls, and rubber gloves.
3. Turn off the system.
To safely access your HVAC system, you need to turn it off. Doing so allows you to reach and clean the drip pan, ducts, heating and cooling units, and evaporator coil. This also prevents you from spreading the cleaning solution fumes around the house, which could lead to serious health problems.
4. Vacuum and scrub problem areas.
Once you have prepared everything you need for mold removal, it’s time to scrub. Apply the cleaning solution directly to the moldy area with the use of a spray bottle, light brush, or wet rag. Let it sit for a few minutes before using a disposable towel to remove the excess solution.
As an added precaution, you can vacuum the area once it has been cleaned. This step may be repeated multiple times in areas with a strong presence of mold.
5. Put used rags in a bag securely.
Once you have removed the mold, the rags you used should be properly. Double-bag the moldy rags with thick trash bags to keep the mold from spreading to other parts of your home. Moldy furnace filters can also be disposed of that way.
6. Use an inhibitor to control mold growth.
You can buy commercial mold inhibitors to deal with mold growth in your system. Be sure to look for HVAC-approved and EPA-registered products and apply them to all parts of your HVAC system.
7. Constantly monitor the area for possible mold regrowth.
Mold removal isn’t something you just forget about once it’s done. Mold can grow back in as little as 48 hours, so you need to keep monitoring the problem areas. If mold and mildew keep coming back, you might be dealing with a moisture problem. If that’s the case, you need to call a professional technician for proper HVAC repair services.
