Salt air is quietly eating your AC. We're the only ones who stop it.
Delta T is the only Outer Banks maintenance plan that includes rust prevention on your outdoor unit. Two visits a year, each with a 23-point inspection delivered in a detailed digital report — with pictures and recommendations — so nothing sneaks up on you.
Your HVAC is the third-largest investment most families make.
Home, car, HVAC. It's the only one of the three that sits outside in salt spray all day and does its hardest work in July — and the one most people ignore until it quits.
Rust prevention on your outdoor unit is built into every Delta T plan.
We treat the outdoor cabinet — the shell that takes the salt hit first — to slow corrosion, the #1 reason coastal systems die early. No other maintenance plan on the Outer Banks includes it.
- Protects the cabinet, panels and hardware from salt damage
- Slows the rust-through that lets salt reach what's inside
- Heat pump stand inspected — the first thing to rust out on beach homes
Maintenance pays for itself. Surprises don't.
Heating and cooling are the biggest line on your power bill — roughly 35–50% of a home's total energy use. The U.S. Department of Energy says keeping up with maintenance can cut that by up to 15%, and a regularly changed filter alone saves 5–15%. That's the small win. The big one is the repair bill you never get.
