Do you need to cover your outdoor unit every time it rains? The good news is that outdoor HVAC units are designed to withstand rain and other harsh weather conditions. The bad news is, it isn’t designed to handle extreme weather like storms. If a storm recently passed through your area, it’s highly recommended that you have an AC contractor inspect it.

What Are the Ways Extreme Weather Can Damage Outdoor HVAC Units?
- Wind damage – Strong winds can fell tree branches and create debris that might get stuck in your AC unit.
- Flood damage – Outdoor HVAC units are durable enough to handle a heavy downpour, but not a deluge. Floods that are more than 15 inches deep will soak your HVAC unit’s sensitive electrical components and cause a short circuit. If your area recently experienced heavy flooding, your outdoor HVAC unit will most likely require immediate AC repair.
Important note: To protect outdoor AC units from subzero temperatures, some homeowners cover them with plastic tarps during the winter. If you’re covering your outdoor unit, make sure to use a breathable material to prevent condensation buildup, which can cause corrosion if left unattended.
What About Window AC Units?
Like outdoor AC units, window AC units are designed to withstand harsh weather. However, there are a few additional precautions you should take to keep it in good condition. For instance, a window AC unit will need to be sealed properly to prevent water from infiltrating your interior.
The Importance of Routine HVAC Maintenance
The best way to prevent corrosion and other forms of weather damage is to establish a maintenance routine for your HVAC system. As a rule, your HVAC system should be inspected at least once a year. Remember: Routine maintenance is a must if you want to keep your system in good condition.
