Eight months of heat, three of cooling, and not much rest between
Your furnace in Carlisle works from October through May. On the coldest nights, when the temperature drops to 24°F, it runs long and often, and the igniter and burner cycle over and over to keep the house warm. That kind of steady demand is what wears an igniter down or leaves a blower motor straining.
Then summer comes, only three months of it, but afternoons near 83°F still push your air conditioner hard right after a long winter off. A system that sat idle since spring can struggle to start or fail to cool well on the first hot day. On top of that, Cumberland County has seen 89 damaging wind events and 16 winter storms over the past ten years, and storms like these knock out power. When the power drops and comes back, most systems restart on their own, but a furnace or air conditioner already worn from a long season of running is more likely to fail right after.

Pennsylvania requires contractors to register with the state.
That registration puts the business on file with the Bureau of Consumer Protection and nothing more. Nobody tested this contractor's HVAC knowledge to get that number. The state keeps no record of trade skill, only that the business exists and registered as required. Cumberland County can't layer its own HVAC license requirement on top of that either. Pennsylvania doesn't allow cities and towns to do that. The registration is the only state-level record you'll find here.
For a repair on a heating and cooling system, that record tells you the business is known to the state. It does not tell you who checked the work itself. Anyone touching the gas connections or the refrigerant on this kind of repair is working on the part of the job where a mistake matters most. Pennsylvania's registration was never built to answer for that. It answers for one thing. The business is on file.

- 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 the display is lit at all. If the thermostat looks dead, check your electrical panel for a tripped breaker. A furnace that will not start at all is often a power or thermostat problem, not the furnace itself. If the blower runs but no warm air comes out, or the system tries to start and shuts off again, that points to something inside the furnace, and a contractor will need to look at it. At 24°F on a winter night here, this is not one to sit on.
- Why is my system running but not cooling the house?
- Check your air filter first. A filter clogged with dust chokes off airflow, and a system starved for air cannot pull enough heat out of your home even if everything else works. If the filter is clean, go outside and look at the condenser unit. Leaves, grass clippings, or anything else pressed against the coil will keep it from releasing heat, and the whole system loses its ability to cool. If the filter is clean and the outdoor unit is clear and you are still getting warm air, the problem is inside the system, likely low refrigerant or a failing part, and that calls for a contractor.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it uses them, and the breaker for the system at your electrical panel. Next check the air filter. A dirty filter can cause weak airflow, a furnace that overheats and shuts off, or an air conditioner that struggles to cool. If your system has a condensate line, look for a clogged drain or a float switch that has shut the system off because water backed up. If you have been through a storm recently, given how often this area sees damaging wind, it is also worth checking that nothing outside is blocking or has fallen on the outdoor unit. If none of that explains it, the issue is inside the equipment and a licensed contractor will need to diagnose it.
