When you have a strong sensitivity to almost all chemical products, it can be hard to find an eco-friendly cleaner to use on your air handler evaporator coil. Your evaporator coil is a prime location for mold and mildew growth in your HVAC system, and something as benign as dust is enough to cause damage to the coil. Therefore, when you need to routinely clean your coil, you have to use a substance that actually works as an antimicrobial or it won’t kill the mold spores that collect. But the problem I have is the eco-friendly cleaner that my HVAC supplier currently uses still bothers my lungs considerably. I asked them about using a mild bleach solution but they explained how that could lead to damaging corrosion on the coil and any of the other metal components in the air handler. We tried a vinegar solution but that didn’t seem to be sufficient in removing the microbial buildup that we found. After calling several different chemical supply companies, I finally found a new green cleaner that is supposed to be extremely effective at killing mold while being simultaneously easy on the lungs. It has spearmint and eucalyptus oil as two of the primary ingredients. Not only does it work wonders on my air handler, it also makes my house smell wonderful for a few hours after we do a full clean on my system. Before I loathed the thought of getting my system cleaned, no matter how long it had been since the last one. Now I even open my air handler up and clean it myself in between my service appointments to further the longevity of my air conditioner even more.
