Local Climate
What Hobe Sound's Climate Means for Your HVAC
Hobe Sound 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 Hobe Sound are not the same as inland Florida — and they shouldn't be priced or installed the same way either.
Common HVAC Issues
The Most Common HVAC Problems We See in Hobe Sound
After thousands of service calls across the Treasure Coast, these are the failures we diagnose week after week in Hobe Sound homes. If any of them sound familiar, call us before they turn into a compressor or coil replacement.
Frozen evaporator coils
Florida humidity overworks under-maintained systems — a common Hobe Sound call. We diagnose airflow restrictions, dirty filters, and low-charge issues that cause icing.
Compressor failures from voltage spikes
Summer storms and FPL surges destroy compressors across Hobe Sound. We install whole-system surge protectors and source warranty-replacement Trane, Carrier, and Goodman scroll compressors fast.
Refrigerant leaks at coil joints
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.
Sky-high humidity (60%+ indoor RH)
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.
Mold and mildew on supply registers
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.
Sudden FPL bill spikes
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.
Local Expertise
Why Hobe Sound Homes Need a Coastal HVAC Specialist
Aggressive Atlantic salt-air corrosion
Hobe Sound homes near the beach lose uncoated condenser coils in 5–8 years. We spec Heresite or e-coated coastal-grade systems and wash twice yearly with non-acidic cleaners.
Large-estate zoning & dehumidification
Multi-system, variable-speed, properly-zoned designs done by Manual J — not by guesswork. Dedicated dehumidifiers for square footage that overwhelms even properly-sized AC.
Hurricane preparedness
Surge protection, hurricane straps, elevated pads. We install with the next storm in mind so customers aren't waiting weeks for a post-storm condenser replacement.
