Sewall's Point sits in USDA zone 10a with a humid subtropical climate. Summer dewpoints regularly exceed 75°F from June through September, our AC systems run 12–16 hours per day, and August indoor latent loads can double a home's design moisture removal requirement. Homes within 3 miles of the Atlantic or Indian River Lagoon also face chloride-laden salt air that destroys uncoated aluminum condenser coils in 5–8 years. Equipment selection, coil coatings, and dehumidification strategy in Sewall's Point are not the same as inland Florida — and they shouldn't be priced or installed the same way either.
After thousands of service calls across the Treasure Coast, these are the failures we diagnose week after week in Sewall's Point homes. If any of them sound familiar, call us before they turn into a compressor or coil replacement.
Florida humidity overworks under-maintained systems — a common Sewall's Point call. We diagnose airflow restrictions, dirty filters, and low-charge issues that cause icing.
Summer storms and FPL surges destroy compressors across Sewall's Point. We install whole-system surge protectors and source warranty-replacement Trane, Carrier, and Goodman scroll compressors fast.
Salt air corrodes aluminum coil fins on homes east of US-1. We pressure-test with nitrogen, electronically leak-detect, and re-braze or replace coils with coastal-grade Heresite-coated alternatives.
Oversized or single-stage systems short-cycle and never pull moisture out. We right-size with Manual J, install variable-speed equipment, and add dedicated dehumidification when needed.
Standing condensation, dirty blower wheels, and biofilm in the drain pan all show up as black streaks on ceilings. We sanitize coils, replace drain pans, and add UV-C lights.
A failing capacitor, dirty condenser coil, or partial duct collapse can quietly add $80–$150/month. Our $89 tune-up catches all three before they snowball.
Within 3 miles of the Indian River Lagoon, uncoated aluminum fins corrode through in 5–8 years. We spec Heresite or e-coated coastal-grade equipment as standard.
Sewall's Point's tree canopy holds humidity around homes. We design for dewpoint, add dehumidification where needed, and seal returns to prevent musty air handlers.
Surge protection, hurricane straps on condensers, and elevated pads on flood-prone lots. We install with the next storm in mind.

Yes — Sewall's Point is a core part of our Martin County service area. Same-day for emergencies, scheduled for installs. We're familiar with the waterfront homes and the salt-air challenges they face.
We recommend coastal-grade condensers with Heresite or e-coated coils, twice-yearly coil washing with non-acidic cleaners, and aluminum-clad disconnect boxes. Salt destroys uncoated equipment within 5–8 years in Sewall's Point.
Yes — Sewall's Point homeowners use our marine HVAC division for Cruisair, Dometic, and Webasto systems on boats kept at private docks.
Yes. Many older Sewall's Point homes have undersized returns, original ductwork in attics, and no modern surge protection. We retrofit carefully and respect the home's character.
