Coastal HVAC Corrosion Protection at the Jersey Shore in Somers Point, NJ

Coastal HVAC Corrosion Protection in Somers Point

Much of Somers Point's housing was built before central cooling was normal and often before ductwork was, so heating and cooling arrived separately and at different times. That is why so many houses here run a boiler for heat and something entirely different for cooling.

81% of homes in Somers Point heat with natural gas, so furnace and boiler work is the bulk of what comes up here. (US Census ACS 2022)

The cover that makes it worse

This is the most common well-intentioned mistake at the shore, and it is worth being blunt about.

A full wrap traps moisture

A fitted vinyl cover pulled over the whole unit through the off-season keeps rain out and keeps humidity in. The fins stay permanently damp, salt already on them stays wet and active, and corrosion accelerates rather than pausing. It also makes an excellent winter home for rodents, which chew wiring.

If you cover anything, cover the top only

A lid that keeps leaves and debris out of the fan while leaving the sides completely open is the sensible version. Manufacturers generally say the unit does not need covering at all — it was designed to sit outside.

Seasonal properties need a start-up, not a wrap

A house shut from October to May is better served by a proper start-up before the season than by anything done to it over winter. Systems fail on the first hot weekend precisely because nothing has run since September, and that is a bad weekend to be looking for a technician on the shore.

What salt actually does to a condenser

Sea air carries chloride, and chloride is aggressive toward the aluminum fins and copper tubing that make up a condenser coil. It attacks the joint between them preferentially — galvanic corrosion between two dissimilar metals in the presence of salt and moisture.

The coil is the part that fails, and it fails from the outside in, which is why a shore system can look fine and still be finished.

Why it presents as a refrigerant leak

Corrosion eventually perforates the thin aluminum at the fin-to-tube joint and the charge escapes. The owner experiences a system that cools progressively less well through a season and then stops. A technician finds it low on charge. Both are true, but the cause is the air — and adding refrigerant to a corroded coil is money into something that will leak again within months.

How close is close

Exposure falls off with distance from the water but not sharply, and prevailing wind matters as much as raw distance. On the barrier islands — Ocean City, the Wildwoods, Long Beach Island, Brigantine — assume heavy exposure. Along the bayfront and within a couple of miles inland, assume moderate. Manufacturers publish corrosion warranties that quietly reflect this.
