Rust is not just unsightly, they can be corrosive to the structure of your home. One of the last places you want rust to take root is within your Greenbelt AC system, where they could be hidden from view for months.
So, follow this brief guide to prevent rust problems from developing.
1. Keep filters clean
The best filter in the world is no good if it is too dirty to function, so keep yours clean. Replace and/or clean them regularly in accordance with manufacturer recommendations.
2. Pay attention to and fix leaks right away
The big problem with both rust is moisture. Excess moisture that gets inside your AC system can wreak havoc. The water can corrode the metallic parts inside, giving rust free reign of your blower compartment or ductwork.
So, be aware of things like wall and ceiling leaks, wet insulation or moisture accumulating around the blower compartment. These are not uncommon problems with AC systems because of coil icing, poor condensate drainage and other issues, and they can easily turn into rust problems if left unchecked.
3. Be aware of humidity
If your home is too humid, even while the AC is running, get it looked at. This could be a symptom of an extra moisture source somewhere.
4. Have AC problems fixed professionally
Finally, when you do run into problems with your Greenbelt AC system, have them professionally repaired. Many AC issues are related or the symptom of a larger problem, so fixing one thing may not solve the real issue. De-icing the condenser coil, for example, but not fixing the associated leak, could mean that the problem will come back, and in the mean time there’s plenty of water to cause rust problems.
