Five months of Jackson summer heat on one machine
From May through September, your air conditioner is the only thing standing between your house and afternoons that average 89°F. That's five months of steady running, every year.
Madison County's outdoor units also take a beating from the weather itself. Over the past ten years the area has seen 40 hail events and 45 damaging wind events, with hail as large as 2.5 inches. Any new central air conditioner installed today has to meet the federal minimum of 14.3 SEER2. That's the baseline to start from, not a feature to ask for.

- What size air conditioner does my house need?
- The right size depends on a load calculation, not a chart based on square footage alone. A contractor works through the size of your home, how many windows it has, which way they face, your insulation, and your attic before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the humidity down, so the house feels clammy even at the temperature you set. An undersized one runs nonstop on those 89°F afternoons here and still falls behind. Ask whoever quotes the job to walk you through the load calculation, not just give you a tonnage.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace both together. The outdoor condenser and the indoor coil are matched to work at a specific capacity and efficiency, and pairing a new condenser with an old coil usually means the system never reaches the rating either piece was built for. It can also void the manufacturer's warranty on the new unit. If your indoor coil is old enough that the outdoor unit needs replacing, it has likely logged close to the same years of wear. A contractor can check the coil's condition and tell you whether it has enough life left to be worth keeping.
- Do HVAC contractors in Jackson need a state license to work on my home?
- Ask to see a state contractor license before you sign anything, and check that it's active. A licensed contractor carries the insurance that protects you if something goes wrong during the job, which matters on work that involves refrigerant lines and electrical connections. If a contractor won't show you a license number, that alone is reason to call someone else.
