Four months of hard running in Leonardtown heat
Your air conditioner works from June through September here, and on an afternoon at 86°F it runs long stretches to keep up. That kind of steady demand wears on the parts that keep the system cooling, especially the capacitor that helps the compressor start and the condenser coil that has to shed heat outside.
A tune-up checks the refrigerant charge, tests the capacitor, and cleans the condenser coil so it can release heat the way it's supposed to. Catching a weak capacitor or a dirty coil in the spring means it doesn't fail on the afternoon you need the system most.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Maryland requires HVAC contractors to hold a state license.
Maryland tested the contractor and keeps a record of that license. It belongs to the business that takes the job, not to the one technician who shows up at your door. That business is the one accountable for the work done in your home.
For a maintenance visit, that license covers who is allowed to run the business and take the job. If the technician opens the refrigerant side of your air conditioner, to check the charge or track down a leak, federal law also requires that person to hold EPA Section 608 certification. That rule applies in every state, not just Maryland. So on this job you have the state license on the company that took the work, and the federal certification on whoever actually touches the refrigerant.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil outside, and tests the capacitor and contactor that start the compressor. They also check the evaporator coil, clear the condensate drain line, and change or check the filter. On the electrical side, they tighten connections and check that the system is pulling the right amps. Anyone opening the refrigerant side of your system needs EPA Section 608 certification, which is a federal requirement everywhere.
- How often does an air conditioner need maintenance?
- Once a year, in spring before the heat sets in. Around here that means getting it done before June, since your system runs from June through September and summer afternoons average 86°F. A yearly check catches a weak capacitor or a low refrigerant charge before it fails on a hot afternoon.
- Is AC maintenance worth it?
- Yes, because most AC failures trace back to something small that maintenance would have caught, a dirty coil, a weak capacitor, a clogged drain line. A coil caked with dirt makes the compressor work harder to move the same heat, and that strain is what shortens a system's life. This area also sees real storm activity, 146 damaging wind events and 25 hail events over the past ten years, so a spring check is also a chance to look over the outdoor unit for any damage before summer starts. A contractor can price a maintenance visit for your specific system.
