Lexington Weather and HVAC Load

NOAA's 1991-2020 climate normals put Lexington at 4,432 heating degree days and 1,289 cooling degree days per year. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. A normal year brings 90 nights at or below freezing and 25 days over 90°F. Snowfall averages about 15 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

NOAA storm reports for Fayette County show 4 hail days and 23 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 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

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

What Moves the Price

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

Kentucky Licensing and Efficiency Rules

Kentucky 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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Kentucky the company should carry a state license or registration. Ask for both.

Before You Hire

  • Swap the air filter and check the breaker before you call anyone.
  • Ask for the per-pound refrigerant price before any work starts.
  • If you see ice, shut the system off. Running it frozen can kill the compressor.
