Guaranteed INSTANT Savings on Heat Pump Installation!

Federal tax credits and utility rebates can be a great way to reduce the cost of a heat pump, but the savings usually aren’t available right away. For tax credits, any credit simply reduces the amount of federal taxes you owe when you go to file your return for the year that your new system was installed. And rebates often require an application, paying up front, and then waiting for your rebate to be processed and mailed back to you after your new system is already installed and paid for.

But you can take advantage of Princeton Air’s $500 heat pump installation special and the amount will be taken directly off your bill! Plus, this special is the cherry on top—you’ll still be additionally eligible for the $2,000 tax credit for qualifying systems and any available future rebate savings.
