"Came out same day in 95° heat. Diagnosed a bad capacitor in 15 minutes and had us cool again before dinner. Fair price, super clean work."

What we see in Wantagh
Our trucks roll through Wantagh year-round. Here's what tends to fail and when.
Deep dive · Wantagh
Wantagh sits close enough to the Great South Bay that every outdoor condenser we service south of Merrick Rd shows salt pitting on the aluminum fins by year 6. That changes what we install and how we maintain it. We're the Wantagh HVAC company that specs coastal-grade equipment by default — not as an upcharge.
16–18 SEER2 inverter systems with copper-tube / aluminum-fin coils and stainless mounting hardware. Typical 2.5–3 ton install $7,200–$9,800 same-day.
High-efficiency 96% gas furnaces or cold-climate heat pumps (great fit for Wantagh's smaller ranches). NYSERDA + 25C rebates apply.
$99 diagnostic (waived with repair), most repairs done in one visit — capacitors, contactors, blower motors, ignitors, flame sensors.
Homes south of Sunrise Hwy get coil rinse + fin comb + line-set jacket inspection to stop the corrosion cycle that kills Wantagh condensers by year 7.
