Eleven months of work, most of it in the cold
Your furnace carries the load from October through May. On nights that average 22°F, it cycles on and off for hours to hold the house steady, and every start puts wear on the igniter and the burner. That is most of the year spent working, not a few cold snaps.
Summer asks less but still asks something. Afternoons near 82°F push the air conditioner to run long stretches to keep up, and the coil and the compressor take that strain. The area has seen 18 winter storms and 172 damaging wind events over the past ten years, and storms like that knock out power. Statewide, 15% of households went at least a day without it in 2024. A furnace or air conditioner that was already struggling before an outage like that often does not start back up cleanly once the power is on again.

NOAA nClimDiv, 1991–2020 normals
A new furnace and air conditioner would cut about $170 a year off heating and cooling for a typical Northampton County home.
Estimates for a typical Northampton 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, its name and address on record, nothing more. Nobody tested this contractor on how to wire a furnace or handle a refrigerant line before handing out that number. It tells you the business exists and can be traced. It does not tell you the work will be done right. No town or city in Pennsylvania can add its own HVAC license on top of that, so this is the only state record there is, wherever you are in Northampton County.
For a repair like this, that registration is not what stands behind the work. It is a record that the business is on file, not a check on how the job gets done. Pennsylvania leaves that record as the only state-level answer for heating and cooling work, in Northampton County and everywhere else in the state.

- Why is my heat not working?
- Most no-heat calls come down to a few things. If you have a furnace, check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker and the furnace switch, which looks like a regular light switch near the unit. A dirty filter can also choke off airflow until the furnace overheats and shuts itself down. With nights here averaging 22°F in the winter, a furnace that is down for even a few hours can let a house get cold fast, so if the basics check out and it still will not run, that points to something like the igniter or the flame sensor, and a contractor should take a look.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, start with the filter. A clogged filter cuts off airflow across the indoor coil, and that coil can ice over, which makes the problem worse the longer it runs. Check the outdoor unit too. If the fan is not spinning or the coil around it is caked with grass clippings or dirt, it cannot release heat and the system will run without actually cooling. If the filter is clean and the outdoor unit looks fine, the system may be low on refrigerant, and that is a job for a contractor, not something to top off yourself.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to heat or cool as needed and that the batteries are not dead. Check the breaker box for a tripped breaker, and if you have a furnace, check the power switch next to it. Then check the filter. If it is gray or packed with dust, replace it, since a blocked filter can cause problems that look like something bigger. If you have done all that and the system still is not working right, a contractor will need to look at it, and telling them what you already checked will help them get to the answer faster.
