Repair scenario · 10-year-old example
Window Air Conditioner repair or replace calculator
Compare repairing an aging window air conditioner with a higher-efficiency replacement over five cooling seasons. Change the prefilled values to match the appliance, diagnosis and local prices.
Repair or replace
Compare five-year ownership costs instead of looking only at today’s repair quote.
If the estimated remaining life is under five years, the keep-and-repair scenario includes a later replacement during the comparison window.
Use the quote, remaining life and operating cost together.
This example starts with a $350 repair, a $550 replacement and 2 years of expected remaining life. Those are planning defaults, not a live national quote.
Five-year cost comparison
The repair path is $1,950 and the replacement path is $1,200 under the default assumptions. Because the remaining life is under five years, the repair path also includes a later replacement.
Important check
Cooling hours, climate and local electricity rates can dominate the result. Confirm window fit, cooling capacity, CEER rating and any refrigerant-related repair limits.
Quick answers
Window Air Conditioner repair or replace questions
Should I repair or replace a 10-year-old window air conditioner?
Using a $350 repair, a $550 replacement and the five-year costs in this example, the lower projected-cost path is to replace by about $750. Replace these planning values with a written local quote before deciding.
How long does a window air conditioner usually last?
This calculator uses 12 years as a planning life and 2 years of remaining life for the default example. Usage, maintenance, climate, installation and model quality can move actual service life in either direction.
Do energy savings justify replacing this window air conditioner?
The newer-unit assumption saves about $80 per year, or $400 over five years. Energy is included in the comparison, but repair risk, installation cost, safety and parts availability can matter more.
