Should you start planning for your next HVAC system?

Have a great replacement option in mind before the unexpected happens.

Eighty-three percent of our customers who took the October home energy efficiency quiz correctly answered that heating and cooling is the single largest use of energy in a home. Your HVAC system is critical to your home’s comfort and a big part of your annual energy costs, so it’s a good idea to have a replacement in mind before you need a new system. 

Three signs that your HVAC system may need to be replaced: 
  1. It’s more than 15 years old or needs frequent repairs.  
  2. Your energy usage is going up without any other household changes. 
  3. Your HVAC system struggles to meet thermostat setpoints. 

Luckily, there’s an energy-efficient option: heat pumps. Heat pumps can keep your home comfortably warm during the winter months, but they can also keep you cool in the summer—while reducing your electricity use for heating by around 65% compared to electric furnaces or baseboard heaters. 

And when the time comes to make a change, you can take advantage of special incentives to upgrade your system. 

Illustrated diagrams showing how heat pumps work. In the winter, heat is extracted from the outside air and transferred into the home, while cool air from inside the home is transferred outside. In the summer, warm air from inside the home is transferred out of the home, while cool air is transferred into the home.

How do heat pumps work? 

In winter, heat pumps extract heat from the outside air and transfer it into your home. Even when it’s very cold outside, there is still heat energy in the air that heat pumps extract to warm your home.  

In summer, they work like a standard air conditioner by absorbing unwanted heat in the air inside your home and transferring it to the air outside.

Types of heat pump systems 

Ducted air source

These heat pumps use your home’s existing ductwork. During the summer months, they serve as central air conditioners and lower cooling costs. In winter, they supply more efficient heat and cost less to operate than conventional furnaces, boilers or electric resistance heat. 


Often referred to as a “mini split,” a ductless heat pump is a good alternative to replace a window cooling unit as well as radiators or baseboard heating. They can be an excellent solution for older homes and additions or outbuildings that do not have existing ductwork.

We make the decision easier with special incentives!

We offer a rebate of up to $450 for air-source heat pump systems and $400 per outdoor unit for ductless mini-split systems. 

Plus, heat pumps with a thermal efficiency rating of 75% or more qualify for a federal tax credit of up to $2,000 per year. You may also be able to include installation labor in your cost calculation. Learn more here.  

There’s money hiding in your home, and a few simple changes can help you find it! Learn more about these and other ways you can Save with PPL.

    We replaced our HVAC system a few months ago. July 25, 2023
    Lebo Plumbing, Heating & Air-conditioning Carlisle PA.

    We can provide a receipt and contact info

    It was a Bryant System

    Will this qualify for a rebate?

    It would be helpful to include information on how to find a heat pump that is appropriate for the cold climate of PA and a knowledgeable installer instead of just republishing general info that is currently found all over. More information on the new expanded Federal credits and how they are being adopted in PA would also be helpful.
