Four months of heat load, every year
Centreville only asks for cooling from June through September, but those four months work the unit hard. Summer afternoons average 86°F, and a system that sits idle most of the year has to start up strong when that heat arrives.
Queen Anne's County has logged 104 damaging wind events over the past ten years, along with 10 hail events. An outdoor unit sitting exposed to that kind of weather can end up with a bent fan cage, damaged fins, or a cracked fan blade. If your air conditioner is struggling to keep up or making noise it didn't before, the unit outside 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 tests contractors before they can hold this license, and the license belongs to the contractor, not to any one job. It covers the person or business doing the work across every job they take on, not a separate approval for your repair specifically.
For an air conditioner repair, that license is what stands behind the person working on your system. If the repair involves opening the refrigerant side, the technician also has to hold EPA Section 608 certification, a federal requirement that applies in every state regardless of local licensing. Between the two, Maryland's license accounts for the contractor, and the federal certification accounts for anyone handling refrigerant.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil, which can cause it to ice up and stop cooling. Low refrigerant from a leak is another common cause, and that only shows up as warm air once the charge drops low enough. A failing compressor will also leave you with air movement but no cooling. Only a licensed contractor can open the refrigerant side to check the charge, since that work requires EPA certification.
- Why is my AC leaking water?
- Most water leaks come from a clogged condensate drain line, which backs up and sends water somewhere it shouldn't go. Algae and dirt build up in that line over time and block it. A dirty filter can also cause the coil to ice over, and the water shows up when that ice melts. Less often, the drain pan itself has rusted through and needs replacing.
- Why won't my AC turn on?
- Start with your thermostat. Check that it has power, the batteries are good, and it's set below the room temperature. If the thermostat looks fine, check your breaker panel, since a tripped breaker will cut power to the whole system. Centreville sees a fair number of damaging wind events each year, and storms like that can trip breakers or damage outdoor wiring. If power looks fine on your end, the problem is likely in the unit itself and needs a contractor to diagnose.
