How long does central air conditioning last?

A central air conditioner (AC) should last 15-20 years, according to the U.S Department of Energy. If your air conditioning system is nearing 15 years old, it might be time to start shopping. 

Today’s air conditioners use about 50% less energy than those installed in 1990. But air conditioning still uses five percent of the nation’s total energy. 

Energy-Efficient Air Conditioners

Replacing an older AC system could save 20-40% on your home cooling costs. And Minnesota’s energy utilities offer rebates for high-efficiency heating and cooling equipment. 

Rebates vary by company and from year to year. Find out more from your utility.

Air conditioning maintenance

Spring is the ideal time to make sure your air conditioner is in peak condition. Regular maintenance will extend the unit’s life and maximize its efficiency.

In the fall, use a hose to remove dirt, leaves, and other debris from your AC unit. Covering the equipment will protect it from cold, wet weather and prolong its life.

In the spring, contact us for a central AC tune-up.
