Six months of Vicksburg heat wears an AC down fast
Your air conditioner runs from May through October here, and on a lot of those afternoons it's fighting to keep up with 91°F outside. That's six straight months where the compressor barely gets a break. Compressors that run this hard, this long, wear out their contactors and capacitors sooner than they would somewhere cooler. You notice it as a unit that runs constantly but never quite gets the house to the set temperature, or one that cools fine in the morning and struggles by mid-afternoon.
Warren County has also seen 145 damaging wind events and 16 hail events over the past ten years, with hail up to 2.75 inches. Wind can knock debris into the outdoor unit and bend its fins, and hail that size can dent the cabinet or damage the coil inside it. After a storm, a unit that used to run quiet may start making noise, or the airflow outside the condenser may not feel like it used to.

A new air conditioner would cut about $60 a year off cooling for a typical Warren County home.
Estimates for a typical Warren County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Mississippi 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.
Mississippi requires HVAC contractors to hold a state license.
Mississippi licenses HVAC contractors through the State Board of Contractors. That license is tied to the contractor, not to any single job, so the same license covers this repair and whatever other work that contractor takes on.
For an air conditioner repair, that license is what stands behind the work. Anyone who opens the refrigerant side of the system to fix it also needs EPA Section 608 certification, a federal requirement that applies in every state, on top of the Mississippi license.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil, which can cause it to freeze over and stop cooling. Low refrigerant from a leak is another common cause, and that takes a licensed technician to fix since it means opening the refrigerant side of the system. If the outdoor unit isn't running at all while the indoor blower is, the compressor or a capacitor may have failed. Given how many hours your AC runs from May through October here, worn parts show up faster than in milder climates.
- Why is my AC leaking water?
- Usually the drain line has clogged with algae or debris, and water is backing up instead of draining outside. It can also mean the coil has frozen and is now thawing, which often traces back to a dirty filter or low airflow. A cracked drain pan will leak too, especially in an older unit. Shut the system off if you see water pooling near it so it doesn't damage the floor or ceiling below, and have a technician find where the water is actually coming from.
- 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 your electrical panel for a tripped breaker, since AC units draw enough current that a breaker trip is common. A blown capacitor or a failed control board can also keep the unit from starting, and those need a technician to diagnose. With 145 damaging wind events recorded here over the past ten years, it's also worth checking that nothing outside, like a fallen branch or debris, is blocking or has damaged the outdoor unit.
