Welcome to the Central Air Resource Center
A learning center devoted to helping you make smart central air conditioning purchase decisions.
Know the warning signs.
Most Central Air Conditioning units have a life span of 15-20 years, so it’s prudent to know what to look for:
- Worn compressor or fan controls may lead to low or no performance.
- Corroded wires and terminals can cause inconsistent operation and may short out the unit.
- Leaking refrigerant can reduce efficiency and affect your unit's operation.
- Your HVAC contractor can help you decide if it's time to replace with a thorough inspection.

Proper installation is critical for Central AC performance. This is not a typical do-it-yourself weekend project. In fact many cities or local jurisdictions require a permit because of the electrical work involved.
To be eligible for an Xcel Energy rebate, we require installation by a participating Heating Ventilation Air Conditioning (HVAC) contractor. This assures they have passed our HVAC assessment and can align the right AC equipment with your specific needs. Check the link in the Resource Center to find a contractor.
Always remember to get more than one estimate before hiring an HVAC contractor. That way you can get a mix of pricing and a sense for which contractor is the best choice for you.
To help you keep track of the process, we’ve included a Heating & Air Conditioning Installation Bid Comparison Checklist from Energy Star® as a handy PDF download in our Resource Center at the bottom of this page.
Today's best air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners made in the mid-1970s.
Heating and cooling costs the average homeowner about $875 a year—nearly half the home’s energy bill. If your central air conditioner is more than 12 years old, replacing it with an ENERGY STAR®-certified model could cut your cost by 30%.*
When replacing your central air conditioning unit, look for a Seasonal Energy Efficiency Ratio (SEER) of at least 15. The SEER is an industry-standard measurement that’s used to determine operational efficiency over a season. For more info you can download a Guide to Energy-Efficient Heating and Cooling from our Resource Center.
Good things to know.
A variable speed ECM can add operating efficiency to your blower and greater air comfort.
The higher the efficiency, the quieter it operates. Along with efficiency, consider where the unit will be placed around your home.
Know your thermostat options. Many new thermostats have smart features such as filter replacement reminders, detailed programming options, and various fan operation modes to suit your needs.
Multi-stage units are more costly, but can provide more even, comfortable cooling.
Your contractor will right size your new AC unit with a load calculation. An oversized AC will short cycle, causing more wear and tear on your system, and increase your operating costs. An undersized unit probably won't deliver the comfort you expect.
Airflow issues with your venting should be examined. While re-venting your home may not be possible, some adjustments and fine tuning can help.
Savings that add up! You could cut your energy costs by 30%. And when you add in our great cooling and heating rebates, you can pocket some big savings the very first year.
