Short summers, hard storms

Centre County only asks an air conditioner to run about two months a year, July and August, with afternoons averaging near 80°F. That is not a heavy cooling load compared to hotter places.

The bigger risk here comes from storms. The area has logged 168 damaging wind events and 15 hail events over the past ten years, with hail up to an inch. Wind can bend the thin fins on the outdoor coil or knock the unit loose on its pad. Hail dents the cabinet and flattens fins even when nothing cracks. Either one can restrict airflow across the coil, and a unit that cannot pull enough air through the coil will struggle to cool the house.

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

  • A new one at the federal minimum, 13.4 SEER2$160 a year
  • An older air conditioner$170 a year

Estimates for a typical Centre 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.

The registration puts the business on file with the Bureau of Consumer Protection. Nobody tested the contractor's HVAC knowledge to get that number. No state board is checking the work. Pennsylvania also keeps this uniform. No city or township can layer its own HVAC license on top, so the registration is the same everywhere in the state, Centre County included.

For a repair on your air conditioner, the credential that actually matters is federal. Any technician who opens the refrigerant side of your system has to hold EPA Section 608 certification. That rule applies the same in Pennsylvania as it does anywhere else in the country. That certification, not the state registration, is what tells you the person handling your refrigerant was trained and tested to do it.

Why is my AC not blowing cold air?
Usually it means the refrigerant level is low, the coil has frozen over, or the filter is so clogged that air can't move past it. A dirty filter is worth checking first since you can do that yourself in a minute. If the filter is clean and you still get warm air, the problem is likely inside the system, and running it longer won't fix it. A contractor can check refrigerant levels and look for a leak, since low refrigerant almost always means one.
Why is my AC leaking water?
Most often the drain line is clogged and water is backing up instead of draining outside. It can also mean the coil has frozen and is now melting, which points back to airflow or refrigerant trouble. A clogged drain is simple to clear, but if it keeps happening, something upstream is causing the coil to ice up. Either way, water pooling near the unit means something needs attention soon, since it can damage the floor or the unit itself.
Why won't my AC turn on?
Start with the thermostat and the breaker, since both are common and easy to check. If the thermostat has power and the breaker hasn't tripped, the problem is likely a failed capacitor or a safety switch that's shutting the system down on purpose. With summer afternoons here averaging 80°F, a system that won't start can leave a house warm fast, so it's worth having someone look at it the same day if you can. A contractor can test the electrical parts safely, since guessing at those can damage the system further.
