Heating season on Long Island is long, and the difference between an 80% furnace from 2005 and a modern high-efficiency system shows up on every bill from October through April.
Shoreline Air HVAC installs, repairs, and maintains furnaces and boilers — including the steam and hot-water boiler systems common in older housing stock here — with 24/7 no-heat emergency response in winter.
High-efficiency gas furnaces (up to 98% AFUE) and modern condensing boilers, sized to your home with a real heat-load calculation — not a rule of thumb.
Still burning oil? Conversion typically cuts heating costs 30–50% and opens rebate eligibility.
Winter no-heat calls get same-day response. Frozen pipes cost far more than an emergency visit.
Annual tune-ups keep warranties valid, catch heat-exchanger issues early, and cut mid-winter failure risk.
Heat-load calculation and system options with real operating-cost numbers
Fixed written price with rebate paperwork handled for you
Installation by licensed techs, typically one day
Startup, safety testing, and thermostat walkthrough

Yes — utility and NYSERDA programs regularly cover $500–2,000+ on qualifying high-efficiency equipment, more for heat-pump conversions. We file the paperwork.
