Its natural for you to wonder how nature and the weather in general affects your outdoor air conditioning unit. You may even panic and start calculating your AC replacement cost. Many of the air conditionercomponents incorporated into its structure are made to withstand heavy rainfall, such as aluminum, copper and other water-resistant metals. This, in turn, enables your AC unit to continue operating despite heavy rainfall. In addition, electrical connections are sealed off so that no rain or other moisture can enter the unit.

Rain & Its Effects On Your Air Conditioner

Heavy rain alone shouldnt have an adverse effect on the normal operation of your air conditioning unit, and at times it can even aid in its performance by cooling down the coil and washing away any dust that’s accumulated over time. However, there are a few caveats that will definitely affect your air conditioning unit if left unchecked. Leave it to the experts at Poormans Heating & Air to guide you through these issues.

Storm Damage

While rain may not be your biggest problem, turbulent winds that carry debris such as tree branches and loose concrete can damage the condenser and blow debris into the unit. Make sure to contact an AC or heater repair expert after a storm to have your air conditioner inspected thoroughly for damages.


Even if a heavy downpour may not affect your air conditioning unit, a flood can damage its interior and electrical components. A good rule of thumb is that as long as floodwater doesnt measure more than 15 inches deep your unit should be able to handle it just fine. Should you experience severe flooding, call your trusted HVAC contractor before starting up the unit again.

Component Corrosion

The majority of homeowners choose to cover the exterior part of their AC unit with plastic or other makeshift materialsduring the winter months, This not only applies to your AC unit, but to other components of your HVAC system as well. Should you choose to cover your unit, make sure to purchase a cover that allows for proper ventilation to ensure that trapped condensation doesn’t build up inside the unit, as this may cause components such as wiring, electrical boards and rubber to corrode.
