Learn How to Protect a Heating and Air Conditioning Unit from Heavy Rains

Even though heating and air conditioning units can withstand extreme weather, heavy rain poses a dire threat to their structural integrity. However, the damage doesn’t usually come directly from rainfall. A large number of associated scenarios bring it about.

Here’s how downpours can harm a heating and air conditioning system:

Corrosion

When rain falls, many homeowners tend to cover the AC if the internal components are exposed. Protecting the unit is acceptable in some cases, but you should avoid it. Garbage bags and plastic wraps trap condensation caused by rainfall, which can lead to rusting metal parts.

Instead, go for an item that provides ventilation. A lack of proper openings in the cover may increase the risk of mold growth, causing extra harm to the appliance.

Creatures seeking shelter in the heating and air conditioning unit

Sometimes, the heating and air conditioning unit can get damaged by critters who want to escape storms and high winds. If you turn off the air conditioner due to temperature drops during winter, the metal box is an ideal refuge for tiny animals seeking shelter. They can even turn it into their permanent home if the appliance is shut down for a more extended period. As a result, their nesting materials can jam moving components, leading to breakdowns.

Flooding

A standard heating and air conditioning system can endure all sorts of weather conditions. But if the region is experiencing torrential rain with floodwater exceeding 15 inches, it can spell disaster for the machine. To ensure your unit can withstand the flooding, hire a trusted heating and air conditioning technician to perform an inspection and any necessary modifications.

Air conditioner debris

High winds typically accompany pouring rain. They can bring a flurry of objects that can get stuck in the air conditioner and wreak havoc on specific components. Therefore, don’t ignore storms and strong winds — have a dependable heating and air conditioning professional examine the system for leaves, branches, and other debris.

Lightning and hail

Another attendant phenomenon associated with rain is lightning. Although it’s implausible that a lightning bolt will strike the heating and air conditioning unit, it can hit the house and result in an electrical surge. In turn, it often harms the house’s mechanicals and electronics, including the heating and air conditioning. To help prevent this scenario, install a power surge protector.

On top of that, heavy rain can precipitate hailstorms. Depending on the size, the stones can inflict powerful blows on the system that warrant expensive repairs or replacement.

Hire an heating and air conditioning professional

To verify the extent of the damage, reach out to a seasoned heating and air conditioning team. Licensed professionals have all the tools and knowledge necessary to fix the appliance or install a new one. They can also recommend optimal measures to protect your unit from future storms and rainfall.
