People who live in Florida and other coastal areas are at risk for damaging hurricanes. Even if you don’t live near the coast, Florida residents are prone to coastal rains. Heavy coastal rains contain a combination of salt and air. Salt can cause more damage to your HVAC system than other typical factors. You may not realize you have a coil erosion problem until it’s too late. Just like the sea air erodes the beachfront, it also erodes metal surfaces found on your outside condenser coils.
Coil corrosion will deteriorate the coils that your refrigerant passes through to cool your home. Coil erosion will also cause your system to leak. The main problem with erosion is the fact that you won’t notice it. That’s why it is important to call a qualified HVAC professional to inspect your complete AC system once or twice a year. You will save money in the long run by becoming proactive when dealing with erosion problems.
Ways to Prevent Coil Erosion
Coil erosion can destroy your HVAC system in as little as 18 months if you live right on the coast. A new air conditioning system will last 15-to-20 years. If you leave your coil erosion problem undetected, it could cost you a lot of money in replacement or repairs. Coastal sea spray causes galvanic corrosion that will make your system run longer to heat or cool your home. The best way to control this problem is to have the salt removed.
Some HVAC system manufacturers are applying coatings to the coils during production to combat the problem. There are a number of products on the market that are sprayed or applied onto the coils. Make sure the product you buy has been proven to work in coastal environments. Look for products that don’t require the coils to be removed. Some coatings require you to remove the coil and ship it to the manufacturer.
You will be left without air conditioning for several weeks. You can also rinse your condenser coils off with the garden hose on a regular basis to try to prevent further damage. Even when you maintain your HVAC system, you still need your system checked by a professional technician regularly. A complete HVAC system is an expensive purchase that can be prevented with regular maintenance. A leaking condenser coil will also cost you more on energy bills.
