What Actually Breaks Coastal HVAC Systems

Three failure points cause nearly every commercial and residential HVAC complaint on the Grand Strand — ranked by how often we see them walk through the door.

1
Most Common

Humidity & Oversized Systems

Oversized or poorly sized units cool the air fast without running long enough to pull moisture out — leaving behind clammy rooms, mold risk, and utility bills that don't match the comfort you're getting.

Oversized, mis-matched systemMold risk, high bills
Correctly sized systemDry air, lower bills
2
Coastal-Specific

Salt Air Corrosion

Airborne salt steadily corrodes coils, copper lines, and electrical contacts on any system within range of the ocean — shortening equipment life and causing failures years ahead of schedule.

Unprotected coil life~6–8 yrs
InfiniGuard-protected coil life~14–16 yrs
3
Hidden Cause

Attic Ductwork Loss

Most ductwork in this region runs through unconditioned attics. Leaks pull in hot, unconditioned air and quietly cost 20–30% of your system's efficiency — often without an obvious symptom.

Sealed, inspected ductworkFull system efficiency
The Fix for #2

Salt Air Is Eating Your System.
We've Got the Cure.

InfiniGuard corrosion protection is built specifically for systems sitting in coastal SC and NC air — the kind of environment that quietly destroys ordinary HVAC equipment years before its time.

"Our old unit never stood a chance against the salt air out here. Tri-County put in a new system with InfiniGuard and it's been flawless since."
