Eleven months of work a year, then a storm knocks out the power
Your furnace in Yonkers runs from October through May. On winter nights averaging 24°F it cycles on and off for hours at a time, and every start puts wear on the igniter and the ignition control board. By spring those parts have been through a full winter of it, and a furnace that won't light is usually telling you one of them gave out.
Summer asks less of the system but still asks. Afternoons averaging 82°F push the air conditioner to run long stretches, and the compressor and capacitor take that strain. Add the wind and storms this area sees, 167 damaging wind events and 42 winter storms over the past ten years, and the power itself is part of the problem. Better than one in ten households here lost power for a full day or more in 2024, and when it comes back, a furnace or air conditioner that was mid-cycle does not always restart clean on its own.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical Westchester County home.
Estimates for a typical Westchester County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, New York fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
- Why is my heat not working?
- Start with the thermostat. Make sure it's set to heat and the temperature is set above room temperature, since a setting bumped by accident is more common than people think. If the thermostat looks right, check your breaker panel for a tripped switch, since a furnace that lost power will not respond to anything. Gas furnaces also need a pilot light or an igniter to work, and if that's gone out, the furnace will run the blower but never get warm. With winter nights here averaging 24°F, a furnace that's down for even a few hours is worth calling in a contractor for rather than waiting.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter blocking airflow across the indoor coil. Check it first and replace it if it's gray or clogged. If the filter is clean and the system still isn't cooling, the outdoor unit could be blocked by leaves or debris, or the refrigerant charge could be low, and neither of those is something to fix yourself. A contractor can check refrigerant levels and airflow to find out which one it is.
- What can I check before calling for HVAC repair?
- Check the thermostat first, since the wrong mode or a dead battery causes a lot of no heat and no cooling calls. Check your breaker panel next, since a tripped breaker will shut the whole system down. Look at the air filter and replace it if it's dirty, since a clogged filter can cause both weak heating and weak cooling. If the outdoor unit is covered in leaves or snow, clear it. If none of that changes anything, the problem is inside the equipment and a contractor will need to diagnose it.
