Two months of real heat, then storms the rest of the year
Your air conditioner in Mountain Lake Park only has to work hard from July through August. Summer afternoons here average 78°F, which is not extreme, but a unit that sits idle most of the year still needs to start up clean when that stretch arrives. A capacitor or contactor that has been resting for ten months is the one that tends to fail on the first hot day, not the last.
Garrett County has also logged 63 damaging wind events and 8 hail storms in the last ten years, with hail up to 2 inches. Wind can knock the outdoor unit's fan blades out of true or drive debris into the coil. Hail that size can dent the fins on the outdoor coil, and once those fins are crushed flat, the coil cannot shed heat the way it should.

A new air conditioner would save little on running costs in Garrett County, so the repair decision comes down to the unit's condition.
Estimates for a typical Garrett County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Maryland 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.
Maryland requires HVAC contractors to hold a state license.
Maryland tests contractors before they get this license, and the board keeps a record of who holds one. The license belongs to the contractor, not to any single job, so the same license covers a repair, a new install, or a service call. It tells you the state has checked this contractor's qualifications, not that this particular repair was inspected or signed off.
For a repair on your air conditioner, the part of the job that goes beyond the license is the refrigerant. Any technician who opens the refrigerant side of your system, to fix a leak or recover and recharge it, has to hold EPA Section 608 certification. That certification is federal and applies in every state, so it sits alongside the Maryland license rather than being covered by it.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak, a dirty air filter choking off airflow, or a coil that has frozen over. A dirty filter is worth checking first since you can do that yourself. If the filter is clean and air still feels warm, the refrigerant side needs a licensed contractor, since anyone who opens that part of the system has to hold EPA Section 608 certification.
- Why is my AC leaking water?
- Water around your AC usually means the condensate drain line is clogged or the drain pan has cracked. Algae and dirt build up inside that line over time and block the water from draining where it should. A frozen evaporator coil can also cause this, since it drips water as it thaws. Either way, a contractor needs to find where the water is actually coming from before clearing or replacing anything.
- Why won't my AC turn on?
- Start with the thermostat and the breaker, since those cause more no-start calls than anything inside the unit. Check that the thermostat is set to cool and below room temperature, and that the breaker for the outdoor unit hasn't tripped. If both check out and the system still won't start, the capacitor or the contactor inside the unit has likely failed, and that repair calls for a licensed HVAC contractor.
