Common Heating Problems in Louisville Homes

Louisville winters bring freezing temperatures, ice storms, and rapid temperature swings. The most common heating repair issues we see:

Furnace not producing heat — failed ignitor, gas valve issue, or bad flame sensor

Furnace blowing cold air — thermostat misconfiguration, pilot light out, or heat exchanger problem

Furnace cycling on and off — dirty filter, overheating, or thermostat malfunction

Strange furnace noises — banging (delayed ignition), squealing (belt/bearing), or rumbling (dirty burners)

Heat pump not heating — low refrigerant, frozen outdoor unit, or faulty reversing valve

Uneven heating — ductwork leaks, undersized system, or blocked vents

Carbon monoxide alarm triggered — cracked heat exchanger, blocked flue, or combustion problem (evacuate immediately)

Pilot light won't stay lit — thermocouple failure, draft issues, or gas supply problem

Furnace Repair vs. Replacement — The Louisville Guide

Knowing when to repair vs. replace your furnace saves Louisville homeowners thousands:

Age: Gas furnaces last 15-20 years. If yours is 15+, replacement usually makes more financial sense

The 50% rule: if repair cost exceeds 50% of a new furnace, replace it

Heat exchanger cracks: a cracked heat exchanger is a carbon monoxide risk — replacement is strongly recommended

Efficiency: older furnaces run at 80% AFUE vs. 96%+ for modern high-efficiency units, saving $300-$600/year

R-22 heat pumps: if your heat pump uses R-22, recharging is extremely expensive — replace with an R-410A system

Frequency: more than 2 repair calls per heating season indicates declining reliability

Louisville Winter Heating Challenges

Louisville's IECC Climate Zone 4A creates specific heating challenges:

Average January temperature: 33°F with frequent dips below 20°F

Ice storms — can damage outdoor heat pump units and knock out power for days

Rapid temperature swings — Louisville can see 30°F changes in 24 hours, stressing heating systems

Older homes — the Highlands, Old Louisville, and Germantown have undersized ductwork and poor insulation

High natural gas usage — Louisville Gas & Electric serves most homes with natural gas, making furnace reliability critical

Backup heat — homes with heat pumps need functioning auxiliary/emergency heat strips for Louisville's coldest nights
