For an HVAC contractor in North Castle, NY, call Bella Family Air Solutions, the family business just south of the town line in White Plains. We service oil burners, boilers with tankless coils, furnaces, central air and water heaters from North White Plains to Armonk and out to Banksville, and our emergency line is answered 24 hours.
North Castle starts at the northern edge of White Plains, and its southern hamlet, North White Plains, is close enough to our Fairview shop that many calls there are 5 to 10 minutes away. Armonk, the town’s largest hamlet, is usually 15 to 20 minutes up I-684 or Route 22, and the far northeast corner near Banksville takes a little longer.
Few towns in central Westchester change character as quickly. Near the White Plains line it feels suburban, with modest homes around the North White Plains train station. A few miles north the roads narrow, the lots get much larger, and many houses depend on oil heat and private wells. We handle both ends of that range, with techs who each have at least 15 years of hands-on experience.
Oil Tanks, Wells and Long Winters

Much of North Castle outside the hamlet centers has no natural gas main in the street. Homes on those roads usually heat with an oil-fired boiler or furnace, with the tank in the basement, a utility room or buried in the yard. Oil equipment is dependable when it’s maintained every year and unforgiving when it isn’t: a clogged nozzle, a dirty oil filter or a weak ignition transformer will lock out the burner on the coldest night of the year. That’s why oil burner service is the backbone of our work here.
Well water adds another layer. Many homes on wells make their domestic hot water with a tankless coil inside the boiler or an indirect tank, so a boiler failure can also mean no showers. Hard or iron-rich well water also builds scale in coils and heat exchangers faster than municipal water, cutting output over time.
Newer and renovated homes increasingly add heat pumps or high-efficiency propane equipment, and plenty of owners keep a generator to hold the heat through outages on tree-lined roads.

From North White Plains to Armonk
Calls in town range from the streets near the North White Plains Metro-North station on the Harlem Line to the Armonk business district on Main Street and the wooded roads toward Byram Lake and the Whippoorwill area. Route 22, Route 128 and I-684 are the main arteries, and the Kensico Reservoir shapes how we route between the hamlets.
A typical North Castle winter call: the oil burner has gone into lockout and the reset button won’t hold it. We check the tank gauge first, then the oil filter, pump strainer and nozzle, then the cad cell and electrodes. After the heating repair, a combustion analysis confirms the flame is clean. Many of these calls are avoidable with an annual tune-up, which is why we push HVAC maintenance so hard in this town.

North White Plains, Armonk and Banksville: one town, three service patterns
North Castle takes its character from three hamlets. North White Plains and Armonk sit on the western side of town, along the Route 22 and I-684 corridor, while Banksville and the rural roads around it fill the eastern side up to the Connecticut line near Greenwich. Town Hall is at 15 Bedford Road in Armonk, and its building department handles permits for all three hamlets.
Each hamlet brings its own kind of call. North White Plains, sharing our 10603 ZIP, has smaller post-war houses on streets where gas service is common and a furnace or water heater replacement is a routine job. Armonk (10504) mixes a compact Main Street with large homes that run several systems at once. Banksville is the most rural: long private driveways, wells, septic systems and oil or propane tanks, where a service van may be the only vehicle on the road after a storm.
Terrain is the constant. Much of the town is wooded ridges and wetlands draining toward the Kensico and Byram Lake reservoirs, so power outages from falling limbs are part of every winter, and heating equipment needs to restart cleanly after the lights come back.
- North White Plains: gas furnaces, water heaters, quick access from the Harlem Line station area
- Armonk: multi-system homes, heat pumps paired with oil or propane backup
- Banksville: oil and propane boilers, well water, long runs from the road

What North Castle homeowners count on us for
Close at the south end, reachable at the north
North White Plains is often 5 to 10 minutes from our Fairview shop up Route 22. Armonk runs 15 to 20 minutes by I-684, and Banksville takes a little longer on the back roads, so we give an honest window instead of a guess.
Full oil burner service, not a quick look
Our preventive oil service covers the nozzle, filter, pump strainer, electrodes and cad cell, then a combustion test. On roads beyond the gas mains, that yearly visit is what keeps the burner from locking out when the temperature drops.
Someone who stays until it runs
One of the themes in our 21 Google reviews is a technician staying until the boiler actually worked. On a rural North Castle property, that commitment matters more, because a second trip up a snowy driveway costs everyone time.
Certified for refrigerant and safety
EPA Universal certification covers the heat pumps and central air systems in newer Armonk homes, and OSHA 30 training covers the ladders, attics and tight crawlspaces common in older North Castle houses. We are licensed, bonded and insured.

FAQ
HVAC questions from North Castle homeowners
Should I convert from oil to gas or a heat pump?
It depends on whether gas is available on your road, which it often isn’t in North Castle, and on the condition of your current system. Heat pumps are an option, sometimes paired with the existing boiler as backup for the coldest days. Our article on converting from oil heat in northern Westchester lays out the tradeoffs.
Why did my oil burner lock out?
The primary control shuts the burner down if it doesn’t detect flame within a few seconds. Common reasons are running out of oil, a clogged filter or nozzle, a dirty cad cell, or air in the fuel line after a delivery. Pressing reset over and over can flood the chamber with oil, so if a single reset doesn’t work, stop and call us.
How often should an oil burner be serviced?
Once a year, ideally before heating season starts. A proper service replaces the nozzle and oil filter, cleans the combustion chamber and heat exchanger, checks the electrodes and pump pressure, and finishes with a combustion test. Skipping it lets soot build up, which lowers efficiency and leads to lockouts at the worst possible time.
Do you service homes in North White Plains?
Yes, it’s one of the closest areas to our shop. North White Plains is a hamlet of North Castle that shares the 10603 ZIP code with our own address, so it’s squarely in our core territory for both routine maintenance and emergency calls. Most homes there are reachable within minutes when the roads are clear.
Do you come out to Banksville in North Castle?
Yes. Banksville is the most rural part of North Castle, on the eastern side near the Connecticut line, and many homes there run oil or propane boilers with wells. It is a longer drive than North White Plains or Armonk, so we give you a realistic arrival window when you call and bring common burner parts on the truck.
My power came back after an outage in North Castle, but the boiler won’t fire. What now?
Check the boiler’s service switch and the breaker once, and confirm the thermostat has power. Some oil burner primary controls lock out after a power flicker and need a single reset. If one reset doesn’t work, stop, because repeated resets can flood the chamber with oil. Call us, and keep sinks on outside walls dripping while you wait.
