Four months of heat, and storms in between
Your air conditioner works hard from June through September here, with summer afternoons averaging 85°F. That is a short season, but a demanding one. The compressor and the fan run for hours at a stretch on the hot days, and the system gets little rest between cycles.
Calvert County has also logged 120 damaging wind events and 14 hail events over the past ten years, with hailstones up to 3 inches. Wind can bend the thin fins on your outdoor unit or knock debris into it, and hail that size can dent the cabinet or damage the fan blade. If your system is blowing warm air or the outdoor unit sounds different after a storm, that is worth a look.

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.
Maryland requires HVAC contractors to hold a state license.
The state license is held by the contractor, not issued job by job, so the same license that covers a full installation also covers a repair call like this one. It comes from the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors, which means the state tested this contractor and keeps a record of them.
An air conditioner repair usually means opening the refrigerant lines, and federal law requires anyone who does that, in Maryland or any other state, to hold an EPA Section 608 certification. That certification is separate from the state license. One says the state has tested and recorded this contractor. The other says the technician handling the refrigerant is federally certified to do it.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter choking off airflow, so start there before anything else. A refrigerant leak will also do this, and it won't fix itself since the system doesn't use up refrigerant on its own. If the outdoor unit is running but the air inside is warm, or if you see ice on the coil or lines, that points to low refrigerant or a failing compressor. Anyone opening the refrigerant side of your system has to hold EPA 608 certification, so this isn't a repair to attempt yourself.
- Why is my AC leaking water?
- Most of the time this is a clogged condensate drain line, and the water backs up and finds another way out. It can also mean the drain pan has rusted through, or the coil has iced over and is now melting faster than the drain can carry it away. A dirty filter or low refrigerant can cause that icing, so the leak is often a sign of a second problem underneath it. Turn the system off if you see standing water. Running it can make the mess worse and won't fix the cause.
- Why won't my AC turn on?
- Check the thermostat first. Make sure it's set to cool and the temperature is below room temperature, and swap the batteries if the screen is blank. If that's not it, look at the breaker box. A tripped breaker will keep the unit from starting at all. Summers here run June through September with afternoons near 85°F, so a system that won't start is worth getting looked at quickly. If the breaker keeps tripping or the thermostat looks fine, the problem is inside the unit and needs a licensed contractor to diagnose.
