Optimize your HVAC. Get a $100 rebate.

Much like your car, your HVAC system needs regular maintenance to work effectively. Don't wait until problems arise on the hottest day of summer or coldest day of winter! Get the peace of mind that comes with getting the most out of your system: Increase its operating efficiency, save energy and money, and improve your home's comfort.


HVAC Audit vs. preventive maintenance vs. tuneup


The HVAC Audit goes beyond an average tuneup, incorporating the best of both preventive maintenance and tuneup services. Your contractor will use a special diagnostic tool to perform a series of tests to help find out precisely what your heating and cooling system needs. Here is a comparison of services that contractors typically provide.*

Tuneup HVAC Audit
Clean filters, outdoor coil and fan yes yes yes
Inspect connections/calibrate thermostat(s) yes yes yes
Test safety controls yes yes yes
Test refrigerant pressures no yes yes
Measure temperature drop and amp draw no yes yes
Test system temperatures and
pressures simultaneously
no no yes
Perform digital calculations based on system data no no yes
Identify issues based on simultaneous readings no no yes
$100 rebate for successful completion* no no yes

Note: This table generalizes services performed. Actual services performed will depend on selected contractor and service needs.

*The HVAC Audit can be completed on electric heat pumps and central air conditioners. If your system registers a 90 percent pre-efficiency index on the diagnostic tool, your system is already running efficiently and you will not be eligible for the $100 incentive.

Frequently asked questions

How do I know if I'm eligible?

To be eligible, you must be a Duke Energy Progress customer, and you must have your HVAC Audit performed by one of our prequalified contractors.

The program is open to residential customers in single-family and manufactured homes that are at least 1 year old. In addition, the program is also available for residential multifamily developments interested in making energy-efficient improvements to their existing residential buildings.

Why should I have a system tuneup?

If you've never had your system evaluated, you could be wasting energy and money. Just as an oil change and tuneup for your car can improve your gas mileage and decrease the wear and tear on your motor, an HVAC Audit of your heat pump or central air conditioner can make your system run more efficiently, while helping to prevent unexpected maintenance repairs. By ensuring that your HVAC unit is operating efficiently, the HVAC Audit can save you money on your energy costs, maximize comfort in your home and extend the life of your equipment.

What is a prequalified contractor?

Each prequalified contractor is a local heating and cooling professional who has met Duke Energy Progress requirements, including completing program training, purchasing the appropriate equipment and completing the Duke Energy Progress paperwork. Only these prequalified contractors are approved to perform the HVAC Audit on behalf of Duke Energy Progress. After the prequalified contractor completes the work, he or she will assist you with submitting the rebate form to receive your cash incentive.

How do I apply for an HVAC Audit incentive?

After the prequalified contractor completes the work, he or she will assist you with submitting the rebate form – and any required documentation – to receive your cash incentive. Simply mail it to the address on the form within 90 days of your HVAC Audit. Once we receive it, you will get your incentive check within four to six weeks.

How will I know what's wrong with my HVAC?

Because the HVAC Audit gets digital readings directly from your system, automatically performs all the required calculations and displays test results and recommendations, you can be assured that the results are accurate. You can also view your system's results on the tool or ask for a printed report.

Are certain weather conditions required in order to perform an HVAC Audit?

Yes. In order for a contractor to correctly analyze your system, the outdoor temperature must be at least 60 degrees. This ensures that the diagnostic tests perform correctly. There are other system requirements that your contractor may discover as he or she takes measurements that may prevent a correct analysis at any given time. If the correct conditions do not exist, the contractor will not be able to perform the HVAC Audit and your service will need to be rescheduled.

How often can I receive an HVAC Audit incentive?

Your heat pump or central air conditioner is eligible for an HVAC Audit incentive once during the life of the equipment.

Can I receive HVAC Audit incentives for each electric heat pump or central air conditioner I have?

Yes. As long as all other requirements are met, you are eligible to receive an incentive for each piece of equipment, once in its lifetime.

What if the contractor doesn't find anything wrong with my HVAC?

If your system is already operating efficiently, you will have the comfort of knowing that your system is at its optimal performance level.

Why does Duke Energy Progress want to help me use less energy?

By 2030, demand for electricity in the United States is expected to grow by approximately 25 percent. In the past, utilities like Duke Energy would build new power plants to keep up with the rising demand for power.

But building new power plants is expensive, and each takes years to complete. Plus, new power plants can have a negative impact on our environment.

The cleanest, most efficient power plant is the one we never have to build. If we can help our customers save energy – and save money in the process – it can reduce the demand for new power plants.
