Bella Family Air Solutions is an HVAC contractor in Mount Vernon, NY for owners of two- and three-family homes, single-family houses on the Northside and small buildings downtown. We repair and service boilers, oil burners, furnaces, central air and water heaters, and we explain what we find before any work beyond the diagnostic begins.

Packed into about four square miles on the Bronx line, Mount Vernon has one of the densest housing stocks in the state, and a large share of it is two- and three-family homes built in the early 1900s. For an HVAC contractor, that means basement boilers doing heavy lifting for several households at once.

Our trucks leave 18 Jefferson Pl in White Plains and usually reach Mount Vernon in about 25 minutes by the Hutchinson River or Bronx River Parkway. Bella Family Air Solutions offers 24-hour emergency service, and our techs each bring at least 15 years of work history to jobs on the North Side, the South Side and Fleetwood.

Original Boilers in Multi-Family Homes

Technician testing boiler venting for carbon monoxide at an old chimney in a Mount Vernon, NY basement

Many Mount Vernon houses still have their original cast-iron radiators and near-boiler piping, even if the boiler itself has been swapped once or twice. Owners often split heat between apartments with separate zones on one boiler, which works well until an air-bound zone or a stuck zone valve leaves one tenant cold while another is overheated.

Gas heat and oil burners both show up here, along with a surprising number of original chimneys that were never lined for a modern appliance. A new high-efficiency boiler or gas water heater vented into an old chimney can cause condensation damage and backdrafting, so we check venting and run carbon monoxide tests on every combustion appliance we service.

Working Fleetwood, Chester Hill and Downtown

Picture a three-family on a side street off Gramatan Avenue in January. The first-floor owner calls because the second-floor tenant has no heat and the boiler relief valve is dripping. A typical cause is a failed expansion tank or an auto-fill valve letting in too much water, which pushes the system over pressure. We isolate the problem, correct the pressure, then drain and purge each zone so all three units heat evenly.

Summer calls lean toward central air in the newer co-ops near the Fleetwood station on the Harlem Line and the single-family streets of Chester Hill. We also field plenty of water heater failures in the older homes near the Mount Vernon East and West stations, where tanks share cramped basements with boilers.

Northside, Southside, the Heights and downtown: four Mount Vernons

Locals divide the city into four parts, and each one brings a different kind of call. The Northside holds Fleetwood, Chester Heights, Huntswood, Estate Manor and Oakwood Heights, with larger single-family houses of three to six bedrooms that often run a boiler for heat and one or two central air systems added decades later. Mount Vernon Heights mixes single-family and multi-family homes on sloping streets. The Southside and downtown are where the densest two- and three-family blocks sit.

Fleetwood, in the 10552 ZIP, has its own character. Tudor-style co-op buildings line the center of the neighborhood along Gramatan Avenue, heated by large central boilers, while the surrounding side streets hold detached houses with their own equipment. A co-op apartment and the house two blocks away need very different service.

The city’s edges are rivers. The Bronx River and its parkway run along the west side, and the Hutchinson River forms part of the eastern border. Low basements near both see water during heavy storms, and that water reaches the boiler, water heater and oil tank first.

FAQ

HVAC questions from Mount Vernon homeowners

Why does my boiler’s relief valve keep dripping in my Mount Vernon two-family?

A dripping relief valve usually means the system is over-pressurizing. The common causes are a waterlogged expansion tank or a fill valve that keeps feeding water. Occasionally the relief valve itself is worn. Never cap or plug a relief valve. Have a tech check the pressure gauge, tank and fill valve, and correct the cause instead of just replacing the valve.

One apartment in our house is too hot and the other is too cold. Can that be fixed?

Usually, yes. Uneven heat between apartments on one boiler often comes down to air in a zone, a stuck zone valve, a failing circulator or a thermostat in the wrong spot. Purging each zone and testing the controls fixes many cases without replacing anything. Our boiler repair service includes that zone-by-zone work.

What should I do if the central air quits during a heat wave in Mount Vernon?

Turn the system off at the thermostat so the compressor is not straining, check the breaker and the filter, and look for ice on the indoor coil. Keep shades drawn and move vulnerable family members to a cooler space. Our heat-wave AC checklist covers the full list, and we answer emergency calls 24 hours a day.

Should each apartment in my Mount Vernon two-family have its own water heater?

It depends on how you bill and how hot water is used. One shared tank is cheaper to install, but one household’s long showers can leave the other short, and a failure affects both. Separate tanks or an indirect tank per zone off the boiler divide the load. Our water heater repair and replacement team can size either setup for your basement.

I own a Fleetwood co-op apartment and have no heat. Who should I call?

Start with your managing agent or superintendent, because heat in most Fleetwood co-op buildings comes from a central boiler the building maintains. If the building hires us, we handle the boiler repair. If your unit has its own ducted central air or furnace, you can call us directly. We don’t service PTAC or window units.
