If your air conditioner’s base looks rusty or corroded, it might not seem like a big deal at first. But underneath that rust, serious damage could be forming especially to the compressor mounts.
The compressor is one of the most expensive and vital parts of your AC system, and a corroded base can quietly shorten its lifespan.
How Corrosion Affects The AC Base
The base of your outdoor AC unit is designed to hold everything steady. When that base begins to rust, it weakens the structure, leading to warping and instability.
Over time, even small amounts of corrosion can cause the metal to bend or sag. This shifts the position of the compressor, which relies on a perfectly level base for balanced operation.
As the base deteriorates, the compressor may start vibrating excessively during each cooling cycle.
These vibrations put added strain on the mounts and bolts that hold it in place. The longer this goes on, the more likely it is that the mounts will crack or fail entirely.
Misalignment And Internal Stress
When the compressor becomes misaligned because of a corroded base, it doesn’t just rattle it struggles.
The refrigerant lines and electrical connections are also affected. Misalignment increases tension on these parts, and over time, this stress can cause small refrigerant leaks or broken connections.
Once refrigerant leaks begin, the compressor has to work harder to maintain the desired temperature, which can lead to overheating and even motor burnout.
Water And Rust Complications
Water pooling is another major issue caused by corrosion. When the base collects moisture from condensation or rain, rust spreads faster.
If the condensate drain gets clogged, standing water accelerates corrosion and spreads rust to nearby parts, including the compressor mounts.
As rust weakens these metal supports, the compressor becomes more unstable, leading to further wear and eventual failure.
Corrosion can also impact nearby electrical components. Rust interferes with electrical conductivity, which can cause shorts, blown fuses, or even complete compressor failure.
Preventing Corrosion Damage
To avoid expensive repairs, schedule regular HVAC maintenance. A professional technician can check for early signs of corrosion, ensure proper drainage, and clean debris that traps moisture around the base.
If corrosion has already begun, addressing it early can prevent more serious damage to your compressor and other components.
