Five months of Oxford summer wears on your AC
Your air conditioner runs from May through September here, and on a 90°F afternoon it doesn't get much rest. The compressor cycles on and stays on longer, and the capacitor that helps start it takes that strain every time. When a capacitor weakens, the outdoor unit hums but the fan won't turn, or the whole system trips off before the house cools down.
Oxford has also seen its share of hail and wind, 20 hail events and 46 damaging wind events over the past ten years. Hail up to 1.75 inches can bend the thin fins on the outdoor coil, and that blocks the airflow the unit needs to cool the air properly. If your air conditioner is running but not keeping up, or the outdoor unit sounds different than it used to, that kind of damage is worth having checked.

A new air conditioner would cut about $60 a year off cooling for a typical Lafayette 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.
Mississippi requires HVAC contractors to hold a state license.
The license is issued to the contractor, not the job, so it covers the person or company doing the work rather than being reissued each time a repair happens. The Mississippi State Board of Contractors is the one testing and keeping records on the people licensed to do this work in the state.
An air conditioner repair usually means opening the refrigerant side of the system, and that is covered separately. Any technician who does that, in Mississippi or any other state, has to hold EPA Section 608 certification. That certification is federal and has nothing to do with the state license. It exists because refrigerant is the part of the job that can go wrong in a way a homeowner cannot see.

- Why is my AC not blowing cold air?
- The most common reason is low refrigerant, usually from a leak somewhere in the coil or line set. A dirty air filter or a coil caked with dust can also block airflow enough that the air coming out feels weak or warm. In summers here with afternoons hitting 90°F, a system low on refrigerant will struggle most during the hottest part of the day. Fixing a refrigerant leak means opening the sealed side of the system, which by federal law takes a technician with EPA 608 certification.
- Why is my AC leaking water?
- Water around your unit usually means the condensate drain line is clogged. Algae and dirt build up in that line over a cooling season and block the water that the coil pulls out of the air, so it backs up and drips out somewhere it shouldn't. A frozen evaporator coil will also leak once it thaws, and that points to a separate airflow or refrigerant problem. Either way, water pooling near the indoor unit is worth having looked at before it stains a ceiling or floor.
- Why won't my AC turn on?
- Start with the thermostat. Check that it has power, is set to cool, and the temperature is actually below the room temperature. If the thermostat looks fine, check the breaker for the outdoor unit, since a tripped breaker is a common and simple cause. Hail is not rare here, with 20 hail events over the past ten years, and a storm can damage the outdoor unit's fan or wiring enough to keep it from starting even without obvious dents. A licensed contractor can test the electrical side and tell you what's actually wrong.
