When the rain starts to pour, you may find yourself concerned about your AC system. After all, a deluge can’t be good for it, right?
You likely have no reason to worry. Your AC unit is designed to resist rain and outdoor damages while also keeping your home perfectly comfortable. There are a few scenarios, however, in which water can cause a headache.
Here are some situations to keep your eye on.
Possible Weather-Related AC Problems
Even though AC systems are made to withstand the strongest rainfall, deep standing water from a localized flood can destroy some moving parts and electronics inside, especially if the depth of the water exceeds 15 inches.
If you’ve recently experienced any severe flooding, it’s best to have your unit professionally inspected before restarting it. In preparation for the future, have your exterior air conditioning unit installed in a flood free area to eliminate risk. You should also make sure your beam houses, venting underneath the pier and ductwork is watertight.
Heavy rains accompanied by strong winds carrying projectiles and other debris can also put the safety of your unit at risk. These extreme conditions can damage the condenser fan grille or carry debris inside your air conditioning unit. It’s highly advisable to give your exterior unit a thorough once-over after any severe storm.
If your AC unit has been improperly wrapped during an off-season, internal corrosion can occur. While it is not mandatory, some people prefer to cover outdoor units, especially when they get plenty of rainfall in winter. Covering reduces the chances of experiencing some of these risks. If you want to cover your unit, use the purpose-built cover recommended by your system’s manufacturer.
The best AC-unit covers have proper ventilation. This prevents moisture and condensation from building up and becoming trapped in the system, which can cause wires and rubber to rot and metal parts to corrode. It also ensures that mold, mildew, insects and vermin do not thrive inside your unit. As a general rule, you should avoid overprotecting your unit since it could actually lead to more severe damage than if you left it uncovered.
Using Your AC in the Rain
Using your air conditioner when it’s raining is perfectly safe, and doing so also helps to dry out the humid air in your house, making you more comfortable. There’s no need to worry about using your unit while it is raining.
The Bottom Line
If there are no problems with your air conditioning unit, it should work perfectly in all weather conditions. Heavy rain alone cannot affect its reliability and performance, but it’s important to watch out for flooding and potential moisture buildup.
