Why You Should Do It

Still struggling with your old, clunky air conditioner?  Keep your home nice and cool and save some money while you're at it by retiring your 15+ year old central A/C and getting a shiny new efficient unit.

What It Costs

Depending on whether you are replacing an existing unit in a forced-air system, or adding ducts and the like to install a system for the first time, you can expect to pay between $2,000 to $10,000 for your unit and installation.

How to Do It

  1. Select “Add to My Challenge” and pledge to replace your central air conditioning unit.
  2. Check your utility’s current rebate programs and the federal tax credits to check their replacement guidelines.  They will recommend a certain Seasonal Energy Efficiency Rating (SEER).
  3. Remember to check big yellow Energy Guide label on the models you are looking for.
  4. Ask your family and friends to recommend a contractor and make sure you tell them you want a high-efficiency model.
  5. Set a date for the installation and make sure you are taking advantage of tax credits, stimulus money, low-interest loans, etc.
  6. Congratulate yourself for making your home more comfortable, saving energy and money, and making a difference for Minnesota!

Make It a Family Activity

Take the kids on a tour of the house and show them the old central A/C unit. Explain that old unit is wasting a lot of energy and will help your family save money.
