For Wisconsin homeowners, residential air conditioning is the best way to stay cooling during the hot and humid days of summer.
Replacing or installing a new air conditioning system can be a big expense and should be left to a heating and cooling contractor who has the experience and skills to do a professional job. Whether you’re upgrading your older air conditioner or buying a new unit, here are some things you’ll want to consider to help you make the right choice:

BTU Capacity
A British thermal unit (BTU) defines the amount of energy that’s required to raise the temperature of one pound of water by one degree. Your air conditioner should have a BTU capacity of between 14 to 26.

AC Size
Available from 1.5 to 5 tons, the size of AC unit you need to cool your home is based on square footage. On average, a one-ton air conditioner can cool 500 to 600 square feet, so for larger homes you’ll need a bigger AC unit.
SEER Rating
The Seasonal Energy Efficiency Rating (SEER) is a ratio that indicates how energy efficient an air conditioner is. The minimum rating of a new AC unit is 13 SEER, with 24.5 SEER now the highest rating available. You may spend more for an air conditioner with a higher rating, but over time you’ll be able to save on energy costs.
Pricing
A central air conditioner will cost you anywhere from $1,500 to $4,000. The price will depend on the size of your home and the AC brand you choose to go with.
To stay cool this summer, call an AC specialist in Wisconsin.
2. Where To Buy Your Air Conditioner
Purchase your AC unit from a reputable store such as Home Depot or Lowe's, or you can buy direct from the manufacturer, including Bryant or Rheem. Since you’ll need to find a heating and cooling contractor to install your air conditioner, you can also rely on their expertise and knowledge for AC recommendations.
3. Quick Tips For Choosing An Air Conditioner
Use these tips to buy the best air conditioning system for your home:
- Determine size – Calculate the size of air conditioner you need to cool your home based on square footage and tonnage.
- Compare price – Get at least three quotes on different AC unit brands and models. Remember to check for sale prices at different locations.
- Compare plans – Check what maintenance and warranty plans come with each different AC unit you’re considering.
- Check ductwork – Consult a heating and cooling contractor to be sure your home has the required ductwork to support central air conditioning.
