Four months of hard running in Aberdeen heat
Your AC has June through September to do its job, and it runs hard those months with afternoons averaging 85°F. That steady load falls on the compressor and the capacitor that gets it started. A weak capacitor can't push the compressor into motion, and the unit hums but never kicks on.
Harford County has also logged 329 damaging wind events and 10 hail events over the past ten years, with hail up to 1.5 inches. Wind drives debris into the outdoor unit and can bend the fan cage or knock the fan out of balance. Hail that size can dent the thin fins on the condenser coil, and once they're crushed the coil can't shed heat the way it should.

A new air conditioner would cut about $50 a year off cooling for a typical Harford County home.

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 license is issued to the contractor, not to each job, so it is the company or person you hire who holds it, not a paper filed for your repair. The Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors is the body that tests contractors and keeps the record of who holds one.
For an air conditioner repair, that license is what stands behind the person working in your house. If the repair means opening the refrigerant side of the system, the technician also needs EPA Section 608 certification. That is a federal requirement, the same in every state, separate from the Maryland license.

- Why is my AC not blowing cold air?
- Most often the filter is clogged enough that air can't move through the coil, and the coil ices over. Low refrigerant from a leak does the same thing, ice builds up and what air does come through is warm. It can also be a failing compressor, and that one a licensed contractor needs to check, since opening the refrigerant side takes EPA Section 608 certification. Check the filter first, but if it's clean and you're still getting warm air, have it looked at before you run the system more and risk the compressor.
- Why is my AC leaking water?
- Your condensate drain line is probably clogged, and water is backing up instead of draining outside. It can also mean the coil iced over and is now melting, which points back to low airflow or low refrigerant. A cracked drain pan will leak too, usually on an older unit. Shut the system off if water is pooling near it, since running it won't clear the clog on its own.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker, both go unnoticed more than people expect. If those are fine, the capacitor may have failed, it's what gives the compressor and fan motor the jolt to start, and when it goes the unit just sits there. With 329 damaging wind events here over the past ten years, a tripped breaker after a storm is worth ruling out before assuming the worst. A contractor can test the capacitor and wiring in a few minutes.
