Built for Hicksville’s 1940s–60s housing stock
Cape Cods, splits and colonials from the same building boom that shaped Levittown next door. A lot of them still run original steam heat, converted oil tanks, or central air bolted onto ductwork that was never designed for it. More on how we work is on our about page.
01
Steam & hydronic heat
Radiators and baseboard loops, sometimes on original Taco zone relay panels that need upgrading – not full replacement.
02
Mid-conversion from oil
A gas line “available on the street” but not yet connected is a common find. We handle the tank, the utility and the new equipment.
03
No room for ductwork
Most of these homes have no attic or wall space for ducts – which is why ductless mini-splits are one of our most common installs here.

FAQ
Got questions?
If you can’t find what you’re looking for, see the full FAQ or call us – we’ll give you a straight answer.
How fast can you get someone out for an emergency?
We offer 24/7 emergency service for no-heat and no-AC calls, and same-day appointments are available. Call and we’ll give you a realistic arrival window before you commit.
Do you work on older Hicksville homes with steam heat?
Yes — a lot of our calls are steam radiators and old baseboard systems in Hicksville’s Cape Cods and colonials. We know how to service them and how to tell you honestly when it’s time to consider a conversion instead.
How much does oil-to-gas conversion cost?
Most Long Island oil-to-gas conversions run about $8,000–$15,000. That covers a new gas boiler or furnace, venting, and removing or abandoning the oil tank. An underground tank or a long gas service run pushes it higher, and you get an exact number after a walkthrough. National Grid runs the gas service to the house; if you’re weighing a heat pump instead, that’s where PSEG Long Island rebates apply.
What’s the average price of a service call?
A diagnostic visit on Long Island typically runs $100–$200. We tell you the exact fee on the phone before anyone comes out, and you approve the repair price before any work starts, so there’s never a surprise on the bill.
Can I get a ductless mini-split if my house has no ductwork?
Yes — many Hicksville homes, especially older Capes, were never built with ductwork. Ductless mini-splits are one of our most common installs for exactly this reason. We’ll talk through single-zone vs. multi-zone based on your layout.
What areas do you service besides Hicksville?
We also serve Levittown, Bethpage, Plainview, Syosset, and Westbury. Not sure if you’re in range? Just give us a call.
