How Does Rainy Weather Affect Your AC?

How Does Rainy Weather Affect Your AC?

Air conditioners are expensive; perhaps, the biggest investment made by homeowners to keep their properties cool and comfortable during the sweltering summer months. Therefore, it is natural for them to worry about the upkeep and maintenance of the units. As a result, many homeowners attempt to protect their ACs, especially the outdoor systems, from rainwater. What they fail to realize is, modern cooling equipment is designed and manufactured to withstand heavy rain damage and continue operating reliably. More often than not, the problems that occur in rainy weather stem directly from people’s clumsy efforts to shield their ACs. Here are a few examples of such malpractices and how to avoid them:

1. Avoiding Internal Corrosion

Central ACs comprise of two components – the indoor air handler with the evaporator coil, and the outdoor condenser. While the latter endures most of the rain, it is sturdy and durable enough to ward off damage. Unfortunately, most homeowners fail to realize this and cover the parts with garbage bags or plastic tarps. The material traps moisture and condensation within the unit, leading to rust formation that eventually eats away at the insides of the system and causes a rapid breakdown. Rainwater dries away with suitable ventilation, but trapped condensation rots the rubber and wiring of the system. What’s more, plastic facilitates the growth of mildew and mold and makes your units habitable for small vermin and insects.

2. Minimizing the Impact of Flooding

Several inches of rainfall from a storm cannot inflict lasting damage on your air conditioner. But deep standing water from localized flooding might cause operational problems. Normally, as long as the floodwaters stay below 15 inches, the electrical parts of your AC’s outdoor systems can survive unscathed. But any further flooding and you might have to call an HVAC professional for inspecting the system.

3. Physical Damage

Most air conditioner models perform admirably during torrential downpours, but the moment high winds and gales come into the picture, you might have a problem on your hands. That is because falling objects, such as tree branches, physically strike the condenser fan grille and deposit leaves and other debris inside. So, your first course of action following a violent storm should be inspecting the interior and exterior of the AC.

In an effort to safeguard their ACs from heavy rainfall, homeowners end up doing more harm than good. They need to consult a qualified, experienced air conditioning service before covering up their cooling unit. To get in touch with one such company, click here.
