Goodman CAP-3L Louvered Ceiling Access Panel for ACST24 & ACST30
Built for Goodman's larger R-32 ceiling mount air handlers, the CAP-3L is the louvered ceiling access panel Goodman lists for the ACST24 (2 ton) and ACST30 (2.5 ton). It finishes the ceiling opening below these low-profile units with a louvered face, a common pairing for bottom-return setups, while keeping the air handler reachable for service. HVAC contractors, multifamily maintenance supervisors, and homeowners with 2-ton or 2.5-ton ceiling units in larger condos and homes use the CAP-3L to finish the install with a Goodman-matched panel.
Is the CAP-3L the Right Panel for Your ACST24 or ACST30?
The CAP-3L fits the larger ACST cabinet shared by the ACST24 and ACST30. It will not fit the 1.5-ton ACST18, which takes the CAP-2L or CAP-2. The fastest check is the model number on the air handler's rating plate. If it begins with ACST24 or ACST30, this is your louvered panel size.
Your return setup is what decides between louvered and solid. Both the ACST24 and ACST30 can be set up for front or bottom return. Louvered panels like the CAP-3L are typically used when return air comes up through the bottom of the cabinet, and the solid CAP-3 is usually used for front return. Check your installation instructions before ordering.
Ideal for: 2-ton ACST24 and 2.5-ton ACST30 ceiling mount air handlers set up for bottom return, in larger condos, townhomes, single-family homes, and multifamily buildings.
Prefer a solid face? The Goodman CAP-3 Ceiling Access Panel, No Louver fits the same ACST24/30 cabinet. Working on a smaller ACST18? Use the Goodman CAP-2L Louvered 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 ACST models is the CAP-3L listed for?
Goodman lists the CAP-3/3L panels for the ACST24 (2 ton) and ACST30 (2.5 ton) ceiling mount air handlers.
Is the CAP-3L the right choice for bottom return?
Louvered panels are typically paired with bottom-return setups, and the solid CAP-3 is usually used with front return. Confirm with your air handler's installation instructions.
What louvered panel do I need for a 1.5-ton ACST?
The 1.5-ton ACST18 uses the smaller CAP-2L. The CAP-3L is too large for that cabinet.
Does the CAP-3L work on a 2.5-ton ACST30 with 10 kW heat?
Panel fitment depends on the cabinet size, not the heat kit. The CAP-3L is listed for the ACST30 cabinet, including models like the ACST30LU1310.
Can I replace an old ceiling grille with the CAP-3L?
If the air handler above is a Goodman ACST24 or ACST30, the CAP-3L is the matched louvered panel. For other brands or older Goodman series, match the panel to that unit's own accessory list.
Why buy the Goodman panel instead of a generic ceiling grille?
The CAP-3L is the accessory Goodman specifically lists for the ACST24/30 cabinet, so you are matching the panel to the air handler rather than guessing at a generic opening size.
