Fortunately, homeowners in 2025 have access to a wide array of federal tax credits, utility rebates, manufacturer incentives, and local energy programs designed to help ease the burden.

In this guide, we'll walk you through:

• What savings are available

• How to qualify

• How to claim them

• And how to potentially save $1,400 or more on your new system

Federal Tax Credits for 3-Ton AC Systems (2025)

Energy Efficient Home Improvement Credit

Thanks to updates under the Inflation Reduction Act, homeowners can take advantage of the Energy Efficient Home Improvement Credit for central AC systems.

• Coverage: 30% of the total equipment cost, up to $600

• Applies to: Qualified central air conditioners and air handlers

• Eligibility: Must meet ENERGY STAR certification and IRS guidelines

• Form Required: IRS Form 5695

Note: This credit is available once per year, per taxpayer. If you're also upgrading other HVAC components (like a heat pump or furnace), coordinate your upgrades to maximize annual caps.

Utility Rebates by Power Companies

Your local electric utility may offer rebates from $200 to over $1,000 based on:

• System efficiency (SEER2/EER ratings)

• Whether you're replacing an older, less efficient unit

• Proof of professional installation and documentation

How to Find Local Rebates:

Use the DSIRE database to look up:

• Rebates by zip code

• Utility-specific forms and deadlines

• Energy efficiency requirements

Tip: Some programs require pre-approval before installation.

Example Rebates:

Utility	Location	Rebate Amount	Requirements
PG&E	California	Up to $750	15.2 SEER2+, licensed contractor
Duke Energy	North Carolina	$300	Old unit removal required

Popular Brands Offering Promotions:
