3 Tips to Keep Your Commercial HVAC System from Rusting

HVAC system


When it comes to your HVAC system, rust is almost unavoidable. Rust develops when metal, oxygen, and water mix together through the process of oxidation. When this happens, rust corrodes the metal, causing it to crumble and flake off. In a furnace, this can become dangerous because cracks can form in the heat exchanger, leading to carbon monoxide leaks. The HVAC system coils can also develop rust, causing them to fail.

Here are three tips to prevent rust from forming in your HVAC system.

1. Look for excessive moisture and corrosives

Excessive moisture is one key cause of HVAC to form rust, and there a number of possible causes or sources of excessive moisture. It could be that the air conditioner is not dehumidifying the air properly. Maybe there’s missing HVAC duct insulation. The HVAC ducts may have leaks or may be sagging.  A proper inspection of your HVAC system can help you determine your rust problem.

Where the HVAC system is located also matters. More humid climates and places like pools, sewers, and high traffic areas can accelerate HVAC rust.

2. Keep the inside of your HVAC clean

Corrosive deposits, oils, and scale can cause your HVAC unit to age prematurely and, ultimately, system failure. To keep your HVAC system running well, invest in regular, preventative maintenance services.
