3 Ways to Protect Your HVAC from Metal Corrosion

Corroded coilDo your customers live at the beach? If so, you know their A/C systems need a little extra TLC from all that salty air.

Over time, salty air can break down the oxide layer that protects parts of the A/C from disintegrating. Check out the photo above – those A/C coils are definitely corroded!

How can you fix corrosion and protect your customers A/C systems? Sea Coast Air Conditioning of Florida has three answers in “How the Beach Damages Your AC.”

One of the best ways is to put a protective layer back on the system.

Sea Coast suggests that “applying an anti-corrosion coating to your air conditioning system can help your AC withstand exposure to the ocean air.”

So what kind of coating do you need? Try a micro-coat that is specifically engineered for metal corrosion like Coil Shield. If you use it for your customers, you can keep their coils protected and clean for one year or more. You’ll see less corrosion and buildup, and the coating unobtrusively covers the coils.

Contractors: What do you use to protect your customers’ coils and A/C systems from corrosion? We all know coil cleaning is a must, but how important is coil protection to you and your customers?

Your HVAC Coils Need a Strong Cleaning – Here’s Why

You just ate an amazing dinner! Perhaps a mouthwatering steak, garlic mashed potatoes, and whatever fixings are your favorite. Now that your stomach is completely full and happy, it’s time to clean up the kitchen. Imagine all the food that just sat on your plate and in the pots and pans.

Now imagine that instead of using soap and water to clean all of the dishes, you just simply rinse the dishes with just water. Would you consider those dishes clean? 

Next, imagine that you just finished up a day of working outside in the hot sun. You’re ready to go inside, take a shower and relax for the rest of the night. You go inside and take a shower with just water. Would you consider yourself clean? 

It’s normal to actually wash our dishes with soap to get them clean, and it’s normal to wash ourselves with soap each day.

So what’s the norm for A/C coils? It’s normal that coils be cleaned, not just rinsed, at least once a year! According to energystar.gov, you should get a maintenance checkup on your A/C system every year. And that checkup should include cleaning the evaporator and condenser coils. As Energy Star states:

Dirty coils reduce the system’s ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.

If someone suggests just rinsing off your coils, they are cutting corners. Remember, the norm is to use a coil cleaner to clean your coil and then rinse off the coil cleaner. 

Just like you use soap in the shower and soap on your dishes, you should be sure that your coils are cleaned with a coil cleaner each year and not just water

Remember, dirty coils can increase energy usage by 30%! But clean coils save you money.
