Air Conditioner Repair

Older air conditioning units often fail with little warning. The strain of cooling your house on the hottest, most humid day of the year can cause its last gasp.

When you call for service, we do our best to repair your air conditioner quickly. We service all air conditioner brands.


Central Air Conditioning Repair & Installation

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 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.
