Furnace Repair vs. Replacement — The Louisville Guide

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

1. 1Age: Gas furnaces last 15-20 years. If yours is 15+, replacement usually makes more financial sense
2. 2The 50% rule: if repair cost exceeds 50% of a new furnace, replace it
3. 3Heat exchanger cracks: a cracked heat exchanger is a carbon monoxide risk — replacement is strongly recommended
4. 4Efficiency: older furnaces run at 80% AFUE vs. 96%+ for modern high-efficiency units, saving $300-$600/year
5. 5R-22 heat pumps: if your heat pump uses R-22, recharging is extremely expensive — replace with an R-410A system
6. 6Frequency: 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:

1. 1Average January temperature: 33°F with frequent dips below 20°F
2. 2Ice storms — can damage outdoor heat pump units and knock out power for days
3. 3Rapid temperature swings — Louisville can see 30°F changes in 24 hours, stressing heating systems
4. 4Older homes — the Highlands, Old Louisville, and Germantown have undersized ductwork and poor insulation
5. 5High natural gas usage — Louisville Gas & Electric serves most homes with natural gas, making furnace reliability critical
6. 6Backup heat — homes with heat pumps need functioning auxiliary/emergency heat strips for Louisville's coldest nights
