How To Protect Your Air Conditioner From Salt Water

If you live in a coastal area, you know how important your air conditioning system is.

When temperatures rise above 80 degrees, open windows and fans simply don’t cut it. You need to blast cold air in every room of your home to feel comfortable.

But what happens if your AC isn’t pumping in the breeze quite as coolly as you’d like?

Well, your first task is to figure out the culprit. For many people on the coast, the villain is saltwater.

Salt Water & Your Air Conditioning System—A Match Made in Hell

That’s right, saltwater could be slowly eroding at the skeleton of your air conditioning unit. The negative effects of salt water on your home and its equipment is very real indeed. Homes, like yours, that are near the coast feel the effects of moisture and sodium chloride in the air. Research shows that even if you live 50 miles inland, salt air can still affect your home.

Salt, in and of itself, is incredibly corrosive. It can easily eat away at the structural components of your home and of course, outdoor equipment like your air conditioner.

Ongoing exposure to coastal conditions can not only reduce the lifespan of your air conditioner but also cost you significantly more in energy bills.

But, how do you know if your AC unit is suffering damage from the environment?

Signs Your Air Conditioner has Salt Damage

The closer you are to the ocean, the more likely you are to have an air conditioner that’s damaged by saltwater.

But there are some clear cut signs that your AC is suffering from saltwater damage, rather than other common AC problems.

A few of these signs include:

Poor cooling performance

Is your AC struggling to keep up with the temperatures? Have you noticed that it takes a lot longer to cool your home to a comfortable temperature? If so, your AC’s cooling performance could be on the decline.

Repeated Parts Issues

Have you found yourself repeatedly replacing different parts in your AC system? That could point to a greater underlining issue, particularly if you live in a coastal area. Even small parts repairs could denote a more serious and chronic issue with your AC.

Equipment Icing Over

Clogged air filters can cause your AC equipment to ice over. This is because restricted airflow can cause your evaporator coil to drop to or below freezing. As a result, ice accumulates on your unit as humidity begins to adhere to it.

Pockmarks on the Equipment

If you notice pockmarks popping up on the outside of your AC unit equipment, it could be a clear sign that you have significant saltwater damage affecting your system.

There are multiple parts on your AC unit that are vulnerable to saltwater damage, including your condenser coil. Another area that can deteriorate quickly on any coast unit, is the aluminum fins. When this happens, airflow is restricted and heat transfer is reduced, causing your entire unit to operate incorrectly

Unfortunately, as these issues add up, your unit’s life is coming to an end. Units that are expected to live 10-15 years, often only survive for 5 years under these conditions.

But there are a few ways you can prevent this from happening.

How to Protect Your Air Conditioning System

Regular AC Inspections

Air conditioners need regular AC inspections to prevent problems associated with or caused by salt-water corrosion. During your inspection, a technician should examine your AC in detail to see if there are any ongoing issues with your unit caused by saltwater.

Purchase the Right AC

Another important thing you can do to prevent dealing with serious and chronic AC system damage caused by saltwater, is purchase the right system. There are specific units that hold up better against the saltwater in your environment. Be sure to speak to the person selling your unit to confirm that what you’re buying is indeed appropriate for the environment.

Have it Properly Installed

Another aspect to consider to protect your home and AC unit from chronic damage is to install it with the environment in mind. Hire a professional to install your unit to ensure that your outdoor unit is located in the right location, considering ongoing saltwater corrosion. For example, installing your unit where rainwater can rinse out any accumulated salts is a great idea and one that a professional team will keep in mind.
