Heating Repair & Installation in Hicksville, NY
Boilers, furnaces and heat pumps in Hicksville’s older homes – diagnosed properly, priced before we start, and sized with a real load calculation.
SystemsWarning signsRepair or replaceCostFAQ
Most of Hicksville was built between the 1940s and 1960s, so the heating in a typical house here is one of four things: a steam boiler feeding radiators, a hot-water boiler on baseboard loops, a forced-air furnace, or a newer heat pump. Each one fails differently – and each has a different repair-versus-replace answer. For forced-air systems, see furnace repair and furnace installation.
Heating Systems We Work On
Steam boilers
One-pipe and two-pipe radiator systems, common in pre-1970 Capes and colonials.
Hot-water (hydronic) boilers
Baseboard loops, circulators and zone valves – often on original Taco zone relay panels.
Gas & oil furnaces
Forced-air systems, including homes that are mid-conversion from oil to gas.
Cold-climate heat pumps
Ducted and ductless heat pumps rated to keep heating through Long Island winters.
Signs Your Heating Needs Service
- Rooms that stay cold, or radiators that heat only partway
- Banging, hissing or knocking pipes – often a pitch or water-level problem on steam systems
- The system turns on and off every few minutes (short cycling)
- Boiler pressure that keeps climbing, or water around the boiler
- A burner flame that looks yellow or lazy instead of steady blue, or soot around the unit
- Heating bills that jump without a change in how you use the house
If a carbon monoxide alarm goes off or you smell gas, get everyone outside first and call 911 or National Grid from outside – then call us.
Repair or Replace?
Age alone doesn’t decide it. A well-maintained cast-iron boiler can last for decades, while a neglected furnace can fail early. What usually tips it:
- A cracked heat exchanger or leaking boiler section – usually a replacement
- Repeated repairs on the same system within a season or two
- A system that was oversized or undersized from the start and never heated evenly
- A planned fuel change – if you’re moving off oil, it rarely makes sense to put money into the old burner (see oil-to-gas conversion)
When replacement makes sense, we size the new equipment with a Manual J load calculation instead of copying the old unit’s size. Older Hicksville homes have often had windows, insulation or additions changed since the original system went in, and an oversized boiler or furnace short-cycles, wears out faster and heats unevenly.
What Heating Work Costs
Heating prices depend on the type of system, how much piping or ductwork has to change, venting, and any fuel change. We give you a firm number after a walkthrough, not a phone guess. For Long Island context, a full system replacement with new ductwork or a heat pump conversion typically runs $14,000–$25,000 – see HVAC installation cost in Hicksville.
Heating FAQ
Should I repair or replace my boiler?
It depends on the boiler’s age and condition, what the repair costs, and whether the system still heats the house evenly. A well-maintained cast-iron boiler can run for decades, so age alone isn’t the answer – a cracked heat exchanger or a leaking section usually is. We’ll show you what we found and price both options so you can decide.
How long does a furnace or boiler replacement take?
A straightforward like-for-like replacement is often done in a day or two. Jobs that change fuel type, move the equipment, or need new venting or piping take longer – we’ll give you the timeline with the quote.
Do you service steam radiator systems?
Yes – steam radiators and old baseboard systems are a big share of our calls in Hicksville’s Cape Cods and colonials, including banging pipes, cold radiators and low-water cutoff problems.
What should I do if I smell gas?
Leave the house right away without switching anything on or off, then call 911 or National Grid’s gas emergency line from outside. Don’t go back in until the utility says it’s safe. Call us after the leak has been handled.
