Goodman CAP-2 Ceiling Access Panel, No Louver, for ACST18 Air Handlers
The Goodman CAP-2 is the solid-face, non-louvered ceiling access panel Goodman specifies for the ACST18, the 1.5-ton (18,000 BTU/h nominal) model in its R-32 ACST ceiling mount air handler series. When a low-profile "pancake" air handler is hidden above a drywall ceiling in a condo, apartment, or small home, the CAP-2 gives you a clean, finished opening to reach the unit for service. Installing contractors, property maintenance teams, and homeowners replacing a missing or damaged panel pick the CAP-2 when they want a smooth, grille-free look on the ceiling.
Is the CAP-2 the Right Size for Your ACST Air Handler?
Size depends on the air handler model, not the room. Goodman matches the CAP-2 to the ACST18 only. The 2-ton ACST24 and 2.5-ton ACST30 share a larger cabinet and take the CAP-3 family instead. Check the model number on the air handler's rating plate. If it starts with ACST18 (for example ACST18MU1305), the CAP-2 is the correct size.
Choose between the CAP-2 and the louvered CAP-2L based on how your air handler's return is set up. Every ACST tonnage has a configurable front or bottom return. A solid, non-louvered panel is typically chosen when return air is ducted to the front of the cabinet, so the ceiling panel only has to provide service access. Confirm your return setup against the installation instructions before ordering.
Ideal for: 1.5-ton Goodman ACST18 ceiling mount air handlers in condos, apartments, small homes, and additions where the return is ducted to the front and a plain, finished ceiling panel is wanted.
Need the louvered version? The Goodman CAP-2L Louvered Ceiling Access Panel fits the same ACST18 cabinet with a louvered face. Running a larger 2- or 2.5-ton ACST? Step up to the Goodman CAP-3 Ceiling Access Panel.
Fitment is based on Goodman's published ACST accessory listing. Always confirm your air handler model number and return configuration before ordering. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Which Goodman air handler does the CAP-2 fit?
Goodman lists the CAP-2 for the ACST18, the 1.5-ton model in the ACST R-32 ceiling mount series. It is not sized for the ACST24 or ACST30.
What is the difference between the CAP-2 and the CAP-2L?
Both fit the ACST18. The CAP-2 has a solid, non-louvered face. The CAP-2L has a louvered face. Choose based on your return configuration and the look you want on the ceiling.
How do I confirm my unit is an ACST18?
Check the model number on the air handler's rating plate. Models starting with "ACST18," such as ACST18MU1305, take the CAP-2 or CAP-2L.
Why choose a panel without louvers?
A non-louvered panel is typically chosen when return air is ducted to the front of the air handler, so the ceiling panel only has to provide service access. It also gives a plainer finished look. Confirm your setup with the installation instructions.
Does the CAP-2 fit older Goodman ceiling air handlers?
Do not go by the panel number alone. In Goodman's older ACNF series, the CAP-2 was listed for a different size. Always match the panel to your exact air handler series and model number.
Who usually buys a replacement CAP-2 panel?
Installing contractors finishing a new ACST18 install, plus condo and apartment maintenance staff and homeowners replacing a missing, cracked, or painted-over access panel.
