Heating systems we service

Whatever heats your home, we know it inside out

Westchester has every kind of heat: century-old steam systems, hot-water boilers feeding cast-iron radiators, gas furnaces, heat pumps and electric baseboard. We repair and maintain all of them, and when it’s time to replace, we install high-efficiency boilers, 90%+ efficient condensing boilers and heat pumps.

  • Steam boilers

    Banging pipes, uneven heat, low-water cutoffs and burners: steam heat rewards a technician who understands it.

  • Hot-water boilers

    Circulators, expansion tanks, zone valves and controls, so every radiator heats evenly from top to bottom.

  • High-efficiency boilers

    A modern boiler, properly sized for your home, burns less fuel than the old one it replaces.

  • Condensing boilers, 90%+ efficient

    High-efficiency condensing boilers recover heat that older boilers send up the chimney, turning 90% or more of the fuel into heat.

  • Heat pumps

    Central and ductless heat pumps that heat in winter and cool in summer.

  • Gas furnaces

    Ignition, heat exchanger, burners, blower and safety controls inspected, cleaned and tested.

  • Radiators & baseboard

    Bleeding, balancing and repair, including electric baseboard and wall heaters.

  • Water heaters

    Repairs and replacements for the tank that gives you hot showers, from the same team that services your boiler.

  • App-controlled thermostats

    Smart thermostats with remote monitoring, so you can adjust the heat and keep an eye on your system from your phone.

Don’t wait for it to quit

Signs your heating needs a technician

  • Some rooms stay cold while others overheat
  • Banging, clanking or hissing pipes and radiators
  • The burner short-cycles: it turns on and off every few minutes
  • Fuel or gas bills climbing without a colder winter to blame
  • Water around the boiler, or a pressure gauge in the red
  • A yellow, flickering burner flame or soot near the unit

Problems with a furnace, boiler or heat pump can be dangerous. Don’t delay. Call (914) 668-8211 and we’ll dispatch a truck and a factory-trained technician, 24/7. Make sure you have working carbon monoxide detectors.

Heating tune-up

What we check on every heating tune-up

Repair or replace?

Honest advice, even when it means a smaller ticket

If a repair will keep a sound boiler or furnace running safely and efficiently, that’s what we’ll recommend. We’d rather save you money by maintaining your existing system.

When replacement does make sense, because of age, repeated breakdowns or running costs, we’ll size the new system properly, explain your options in plain English, and help with financing if you want it.

  • Allstate Air is a great company. I’ve been using them for approx 13 years now. Their repair people that come out are all very nice, especially Winston. He is such a nice man and very very thorough.

Heating FAQ

Heating questions, answered

How often should my boiler or furnace be serviced?

Once a year, before the heating season starts. It's far better to find a problem in September than on the first freezing night, and a tuned system burns less fuel. A maintenance agreement takes care of the scheduling for you.

Should I repair or replace my boiler?

It depends on the boiler's age and condition, how often it's needed repairs, and what it costs to run. We'll give you an honest assessment. If maintaining your existing system is the better value, we'll tell you so.

What is a high-efficiency condensing boiler?

A condensing boiler captures heat from its exhaust that a conventional boiler sends up the chimney, so it turns 90% or more of its fuel into heat (an AFUE rating of 90%+). Many older boilers run well below that. We install both high-efficiency and condensing boilers, and we'll tell you which one suits your home and heating system.

Why are my radiators cold at the top?

On hot-water systems that usually means trapped air. Bleeding the radiators at least once a year improves efficiency and comfort. If bleeding doesn't fix it, or you have steam heat, give us a call.

Do you service water heaters?

Yes. We repair and replace water heaters as well as boilers, furnaces, heat pumps and electric baseboard heat.
