Three months of real heat, then long stretches with the system off

Your air conditioner in Dauphin County only gets three months of real work, June through August, with afternoons averaging 82°F. That is a short season, but it is a demanding one, and the system sits idle most of the year in between.

A unit that starts and stops through a stretch of hot afternoons, then sits unused for months, is the kind that has trouble waking up. Capacitors weaken sitting through the off season. Contactors pit from the current of those first hot days. Dauphin County has also logged 149 damaging wind events and 20 hail storms in the last ten years, with hail up to 1.75 inches. Wind and hail like that can bend the fins on your outdoor unit or damage the fan, and you may not notice until the next time you need it and it struggles to keep up.

A new air conditioner would save little on running costs in Dauphin County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$260 a year
  • An older air conditioner$280 a year

Estimates for a typical Dauphin 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 a business on file with the Bureau of Consumer Protection. Nobody tested the contractor's trade knowledge to get it, and nobody checks their repair work afterward. It just means the state knows the business exists and can act on it if a homeowner files a complaint. Dauphin County and every municipality in it are barred from layering on their own HVAC license, so this registration is the only state-level record that applies here.

For a repair like this, the protection that actually reaches the work is federal. Anyone opening the refrigerant lines on your air conditioner has to hold EPA Section 608 certification, and that rule holds in Dauphin County the same as anywhere else in the country. It is not a license and it does not cover the electrical or mechanical side of the repair. It only says the person handling the refrigerant was tested on doing that safely.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter choking off airflow across the coil, which can cause it to freeze up and stop cooling. Low refrigerant from a leak is another common cause, and that will not fix itself since your AC does not use up refrigerant over time. If the outdoor unit isn't running at all while the indoor fan blows, the compressor or a capacitor may have failed. Check the filter first, and if it's clean, the system needs a contractor to look at the refrigerant charge and the outdoor unit.
Why is my AC leaking water?
Water around your indoor unit usually means the condensate drain line is clogged. Algae and dirt build up inside that line over a summer of steady use and eventually block it, so the water backs up and finds another way out. A frozen evaporator coil will also cause water on the floor once it thaws, so if the system has been running with low airflow or low refrigerant, that's the drip you're seeing. Either way, a contractor can clear the line or find what's causing the coil to freeze.
Why won't my AC turn on?
Start with the thermostat. Check that it's set to cool and the temperature is below the room temperature, and if it runs on batteries, try fresh ones. If the thermostat looks fine, check your electrical panel for a tripped breaker, since a hard-working compressor on an 82°F afternoon can trip one. If the breaker is fine and the system still won't respond, the problem is likely inside the unit and needs a contractor to diagnose it.
