Our Fitment Guarantee

Every part we sell is guaranteed to fit your HVAC unit — or your money back.

How It Works

Every OEM part on NationalHVACParts.com is cross-referenced against the manufacturer's original equipment specifications. When you see "OEM" on a listing, it means the part meets the exact same specifications as the factory-installed component.

What's Covered

If any OEM part you purchase from us does not fit or function correctly in the unit specified in the product listing, we will:

1. Send you the correct part at no charge, OR
2. Issue a full refund including return shipping

How to Use

Before ordering, verify your unit's model number (found on the data plate). Enter it in our Part Finder or search by model number. Every product listing shows which models it's compatible with.

Need Help?

Call us at 1-800-NHP-HVAC or use the chat widget. Our team can verify fitment before you order — just have your model number ready.
