On average, Lafayette gets 18 freezing nights and 80 days above 90°F per year. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 14 days with damaging thunderstorm winds in Lafayette Parish. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Symptoms Worth a Service Call

  • The breaker trips when the AC kicks on
  • Ice on the refrigerant lines or the indoor coil
  • The outdoor unit hums, but the fan doesn't spin
  • The system cycles on and off every few minutes
  • The AC runs, but the air coming out is warm

What Moves the Price

  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Whether the equipment sits in a tight attic or on a roof
  • Refrigerant type and how many pounds it takes
  • Nights, weekends and holidays
  • The service call or diagnostic fee

We raised the national figures about 4% for Lafayette using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • A test run
  • Replacing the failed part
  • Clearing the drain line if it's clogged
  • Diagnosis and electrical testing
  • Checking refrigerant pressures

Louisiana Licensing and Efficiency Rules

Louisiana is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Louisiana license or registration number before the visit.

Before You Hire

  • If you see ice, shut the system off. Running it frozen can kill the compressor.
  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
  • Ask for the per-pound refrigerant price before any work starts.
