AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

HVAC in Lexington, KY: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Kentucky licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Blue Grass Airport (KLEX) is the official NOAA reference station for Lexington. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00093820), Lexington records an annual mean temperature of 56.3°F, an average annual maximum of 66.3°F against an annual minimum of 46.3°F, approximately 4,432.4 annual heating degree days against 1,289.0 cooling degree days, an annual precipitation normal of 49.84 inches, and an annual snowfall normal of 14.5 inches. The roughly 3.4:1 HDD-to-CDD ratio reflects a heating-leaning dual-load climate — equipment must handle Kentucky’s cold winters while also delivering adequate summer cooling and dehumidification in the Bluegrass region’s humid climate.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Lexington-Fayette urban county, Kentucky) report 137,803 occupied housing units with a median year built of 1983. Heating-fuel distribution: 57.2% electricity (78,859 units), 40.8% utility natural gas (56,275 units), and 1,610 on bottled/tank/LP gas (1.2%). The electricity-majority profile is notable for a Zone 4A city — reflecting Kentucky’s historically affordable coal-generated power, which made electric-resistance and heat-pump heating competitive with gas.
Kentucky Licensing Authority
Kentucky requires HVAC contractors to hold a Master HVAC Contractor License issued by the Kentucky Department of Housing, Buildings and Construction (DHBC). The DHBC administers examinations and issues licenses for HVAC contracting statewide. Verify a specific contractor’s current DHBC license status before contracting. Primary source: Department of Housing, Buildings and Construction.
