Eleven months of work, most years

Your system in York County only gets a short break. Heat runs October through May, and cooling picks up in June through August. That leaves one month of rest a year, if it gets one at all.

Winter nights averaging 24°F mean the burner or heat pump is cycling on and off for hours at a stretch, and every start puts wear on the igniter or the parts that switch it on. Come summer, afternoons near 83°F push the compressor hard for months at a time. On top of that, York County has logged 15 winter storms and 205 damaging wind events over the past ten years, and storms like these knock out power. When it comes back, your system needs to start up on its own, and anything already weak from the season's work is what tends to fail first.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical York County home.

  • A new furnace and AC$860 a year
  • An older furnace and AC$1,020 a year

Estimates for a typical York County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Pennsylvania 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.

Pennsylvania requires contractors to register with the state.

That registration puts the business on file with the state and nothing more. Pennsylvania does not test HVAC contractors or issue them a trade license, so the number tells you the business is registered, not that anyone checked its work.

Since there is no license behind this job, no state exam or credential stands behind the person doing the repair. Cities and towns in Pennsylvania cannot require their own HVAC license either, so that registration is the only state-level record that applies to whoever works on your system here.

Why is my heat not working?
Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that it has power or fresh batteries. If that is fine, look at your breaker panel, since a tripped breaker will cut power to the furnace even when the thermostat display is lit. Gas furnaces will also shut down if the pilot or igniter fails, or if a safety switch trips, and at 24°F on a winter night here that is not something to leave until morning.
Why is my system running but not cooling the house?
Check your air filter first. A filter clogged with dust blocks airflow across the coil, and the system can end up running constantly without bringing the house down to temperature. Next check that the outdoor unit is not blocked by leaves or debris, since it needs open airflow around it to move heat outside. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have a failing part, and that calls for a contractor to check it.
What can I check before calling for HVAC repair?
Check the thermostat settings and batteries first, since a wrong setting or dead batteries look exactly like a bigger problem. Then check your breaker panel for a tripped breaker and your furnace's own switch, which looks like a light switch near the unit. Check the air filter too, since a dirty one can cause both weak heat and weak cooling. If everything there checks out, tell the contractor what you found. It helps them get to the actual problem faster.
