Five months of hard running in Oxford heat
Your air conditioner works from May through September here, and on the afternoons that hit 90°F it runs long stretches just to hold the house steady. That kind of demand wears on the parts that keep it running, the capacitor that gets the compressor started, the contactor that switches it on and off, the condenser coil that has to shed heat outside in that same 90°F air.
Oxford has also seen its share of hail and wind, 20 hail events and 46 damaging wind storms over the last ten years. A tune-up is when a contractor checks the outdoor unit for bent fins or a cracked cabinet from a storm you might not have connected to how the system runs, along with the wear that just comes from a long, hot summer.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Mississippi requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to any single job, so it covers whoever the state has on record running that business, not just the crew at your door. It means Mississippi tested this contractor and keeps them on file with the State Board of Contractors.
For a maintenance visit, that license is what stands behind the work. If the technician opens the refrigerant side of your air conditioner to check charge or pressure, they also need EPA Section 608 certification, which every state requires for that kind of work. Mississippi's license covers the business doing the job. The federal certification covers the person handling the refrigerant.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil outside, and tests the capacitor and contactor that get the compressor running. They also check the electrical connections and confirm the thermostat is calling for cooling correctly. Anyone who opens the refrigerant side needs an EPA Section 608 certification, and Mississippi requires the contractor they work for to hold a state license.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts, is enough for most systems. Here that means getting it done before May, since homes run their AC from May through September. Summer afternoons average 90°F, and a system that goes into that kind of heat with low refrigerant or a weak part will run harder than it should.
- Is AC maintenance worth it?
- Yes, because most of what fails in an air conditioner fails slowly and shows warning signs a technician can catch early. A weak capacitor, a dirty coil, or a low refrigerant charge all make the system run harder without shutting it down right away. Catching those during a checkup matters more here than in places with a shorter cooling season, since this system runs five months a year with afternoons averaging 90°F.
