Step 1 of 3: Equipment
An unfinished basement containing a metal furnace with ductwork, exposed wooden joists on the ceiling, cardboard boxes, a coiled cable, and a single hanging incandescent bulb.

Ten months of work, most of it in the cold

Your furnace is the one doing most of the work here. Heat runs October through May, eight months, on nights that average 19°F in the dead of winter. That means long stretches where the burner is cycling on and off for hours, and every start puts wear on the igniter and the flame sensor. When one of those finally gives out, the furnace either won't light or shuts itself off partway through a cycle, and you'll notice the house not holding heat the way it should.

Summer is short here, just July and August, with afternoons around 79°F. That's not extreme heat, but it's enough that a struggling air conditioner still gets found out, especially after sitting unused most of the year. This area has also seen its share of winter storms and damaging wind, and gas furnaces with electronic ignition won't restart on their own after a power drop. If yours doesn't come back on once the power does, that's the first thing worth checking.

A new furnace and air conditioner would cut about $180 a year off heating and cooling for a typical Ontario County home.

  • A new furnace and AC$890 a year
  • An older furnace and AC$1,070 a year

Estimates for a typical Ontario 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?
Most often it is the igniter, a flame sensor that needs cleaning, or the thermostat calling for heat but not getting a response from the furnace. Check that the thermostat is set to heat and the temperature is above room level, and check the breaker or switch on the furnace itself. With winter nights here averaging 19°F, a furnace that will not fire needs a contractor out the same day, not next week.
Why is my system running but not cooling the house?
The fan is moving air, but something is stopping that air from actually cooling it. A dirty filter blocks airflow across the coil, and a coil that is frozen or coated in dust cannot pull heat out of the air even with the blower running full speed. Low refrigerant from a leak causes the same thing, cold air stops coming out of the vents even though the unit runs. Check the filter first since it takes a minute and solves this more than people expect.
What can I check before calling for HVAC repair?
Start with the thermostat. Make sure it is set to heat or cool as needed, the batteries are good, and the temperature you have set is actually calling for the system to run. Next check the filter, a filter clogged with dust chokes off airflow and can cause a furnace or air conditioner to shut down on its own. Check the breaker panel too, since a tripped breaker will stop the system cold with no other symptoms. If the outdoor unit is covered in leaves or ice, clear it, since it needs open airflow to work. If none of that fixes it, a contractor can diagnose what is actually wrong.
