Efficiency & refrigerant
Refrigerant type was not published for this listing. Note the 2025 transition: new residential systems must now use low-GWP refrigerant (R-454B or R-32) under the EPA AIM Act, while existing R-410A units remain serviceable.
Rebates & tax credits
This category does not have its own line in the federal 25C tax credit. Some matched-system components may still factor into a qualifying installation — confirm with your installer. See the federal credit details →
This is not tax advice. We do not know this exact model's certified efficiency rating, so we cannot say it qualifies for any specific amount. Eligibility depends on the installed system's AHRI-matched rating, your tax liability, and the home being your residence. Always confirm with your installer and a tax advisor.

A retailer "system bundle" is not proof of an AHRI reference number. Verify the match in the AHRI Directory.
Before you buy or install
A PTAC or through-the-wall unit is sized to the room and to a standard wall-sleeve opening — confirm the sleeve dimensions and the electrical plug/voltage before buying. Heat options (electric resistance vs heat pump) and the required circuit amperage vary by model. These are usually plug-in, but the wall sleeve and circuit should be confirmed by a qualified installer.
Maintenance
Clean the front filter monthly and vacuum the coils periodically. Keep the room-side intake unobstructed; a dirty filter is the most common cause of weak cooling.
