Four months of hard running in Denton summers
Your air conditioner works June through September here, and Denton afternoons average 86°F through the summer. That is the stretch where the system runs longest and hardest, cycling on and off all day to keep up.
Caroline County has seen 75 damaging wind events over the past ten years, along with a couple of hailstorms. Wind can knock debris into the outdoor unit or rattle loose the wiring and refrigerant lines running to it. If your AC is struggling or not cooling right after a storm rolls through, that outdoor unit is the first place to look.

A new air conditioner would cut about $50 a year off cooling for a typical Caroline County home.
Estimates for a typical Caroline 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.
The state tests contractors before they get a license, and the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors keeps the record. That license belongs to the contractor, not to any one job, so the same license covers the repair on your air conditioner as it would a furnace install or a water heater swap.
For an air conditioner repair, that state license is what stands behind the work. If the repair involves opening the refrigerant lines, the technician also needs to hold EPA Section 608 certification, which is a federal requirement in every state, not something Maryland adds on top. Between the two, the license is what Maryland put in place to answer for the work done in your home.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil. When that happens the coil can ice up, and once it's iced over the air coming out of your vents turns warm even though the system is running. A low refrigerant charge causes the same thing, usually from a slow leak rather than the system using it up. Check the filter first. If it's clean and you're still getting warm air, the system needs a contractor to check the charge and look for a leak, since refrigerant work has to be done by someone with EPA 608 certification.
- Why is my AC leaking water?
- Your AC makes water constantly while it runs, pulling moisture out of the air as it cools it, and that water is supposed to drain out through a condensate line. The leak means that drain line is clogged or the pan under the coil has rusted through. Algae and dust build up inside that line over time and block it, backing water up until it overflows. A contractor can clear the line or replace the pan depending on which it is.
- Why won't my AC turn on?
- Start with the thermostat and the breaker. If the thermostat screen is blank, check the breaker for the indoor unit and the disconnect switch by the outdoor unit, since either one tripping will shut the whole system down. If power looks fine, the capacitor that starts the compressor may have failed, which is a common reason a unit gets power but never starts. That's a repair for a contractor, since the capacitor holds a charge even after the power is off.
