Eleven months of work a year in Murrysville
Your furnace and your air conditioner are almost never both off here. Heat runs October through May, and cooling picks up for June through August. That leaves one month where the system rests.
Winter nights averaging 23°F mean the burner fires often and runs long to keep up. That kind of run time wears on the igniter and the blower motor. On the cooling side, afternoons near 81°F push the compressor hard through the summer months. When a part is close to failing, you tend to notice it first on the coldest nights or the hottest afternoons, right when the system is working hardest.

NOAA nClimDiv, 1991–2020 normals
A new furnace and air conditioner would cut about $170 a year off heating and cooling for a typical Westmoreland County home.
Estimates for a typical Westmoreland 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 Bureau of Consumer Protection. It does not mean anyone tested the contractor's HVAC knowledge, and there is no state license number attached to the work. Pennsylvania also does not let cities or townships layer their own HVAC license on top, so the registration is the only state-level record you get, wherever in Westmoreland County you are.
For a repair on a system that burns gas and moves refrigerant, that registration is not what stands behind the work itself. It confirms the business is on file, nothing more. Pennsylvania's rule does not include a trade exam or an inspection of a gas connection or a refrigerant line, so on this job the registration is a record of who the contractor is, not a check on how the repair was done.

- 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, and check that the display is lit at all. If the thermostat looks dead, check the breaker for your furnace and any switch that looks like a light switch near the unit, sometimes it gets bumped off. Gas furnaces need power for the igniter and blower even though gas does the heating, so a tripped breaker or blown fuse will stop the whole system cold. If power and the thermostat check out and you still get no heat, that points to something a contractor needs to look at, like an igniter, a flame sensor, or a pressure switch.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the coil can ice over so the air coming out feels weak or barely cool. Next check that all your supply vents are open and not blocked by furniture or rugs. If the filter is clean and the vents are open but the air still isn't cold, the system may be low on refrigerant or have a failing part outdoors at the condenser, and that needs a contractor with gauges to find out.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it uses any, and the breaker for the system. Check the air filter and replace it if it's gray or thick with dust, since a clogged filter causes both weak heat and weak cooling. Look at the outdoor unit if you have one and clear away leaves, grass clippings, or anything piled against it. If you've done all that and the problem is still there, tell the contractor what you checked, it helps them get to the actual cause faster.
