Three months of hard running, and hail on top of it
Your air conditioner in Chambersburg only gets three months to do its job, June through August, and it has to work hard in that window. Summer afternoons average 84°F, so the compressor runs long hours trying to hold the house steady. That kind of steady demand wears on the parts that keep it running, especially the capacitor and the contactor that cycle the compressor on and off.
Franklin County has also seen 78 damaging wind events and 15 hail events over the past ten years, with hail up to 1.75 inches. Wind can knock debris into the outdoor unit or rattle it loose from its pad. Hail that size can bend the thin aluminum fins on the condenser coil, and once those fins are bent shut, the unit can't shed heat the way it should. You may notice the air isn't as cold as it used to be, or the system runs longer than it seems like it should to cool the house down.

A new air conditioner would save little on running costs in Franklin County, so the repair decision comes down to the unit's condition.
Estimates for a typical Franklin 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 a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Pennsylvania requires contractors to register with the state.
That registration puts the business on file with the state and nothing more. Nobody tested this contractor's HVAC knowledge to get that number, and no state board is tracking complaints against it the way a license would. Pennsylvania also blocks cities and towns from layering on their own HVAC license, so this registration is the only state-level record that exists anywhere in the commonwealth.
What actually governs this repair is federal. Since the job involves opening the refrigerant side of your air conditioner, whoever does the work has to hold EPA Section 608 certification, the same requirement that applies in every state regardless of what Pennsylvania does or doesn't license. That certification is what says a technician was tested on handling refrigerant safely, not the state registration.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter choking off airflow, so check that first and replace it if it looks gray or packed with dust. Low refrigerant from a leak is another common cause, and that will need a contractor to find the leak and recharge the system. A frozen evaporator coil can also cut off cold air, usually because airflow was restricted long enough for ice to build up on it. If the outdoor unit isn't running while the indoor fan is, the compressor or a capacitor may have failed.
- Why is my AC leaking water?
- Most water around an AC comes from a clogged condensate drain line, where algae and dirt build up over time and block the water from draining outside. When that line clogs, water backs up and spills from the drain pan instead. A frozen evaporator coil that then thaws can also flood the pan faster than it can drain. Either way, the fix is clearing the line or finding what's causing the coil to freeze, not just wiping up the water.
- Why won't my AC turn on?
- Start by checking the thermostat. Make sure it's set to cool and the temperature is set below the room's current temperature, and replace the batteries if the display is blank. If the thermostat looks fine, check the breaker panel. A tripped breaker will keep the whole system from starting, and Chambersburg sees a fair number of damaging wind events each year that can trip one or knock out power to the outdoor unit without you noticing right away. If the breaker is fine and the thermostat is calling for cooling but nothing happens, the capacitor or contactor in the outdoor unit may have failed, and that's a job for a contractor.
