Biggest Square Possible ⏹️

The goal is simple:

Choose the largest square AC Shade frame that will comfortably sit on top of your condenser.

It doesn't matter which measurement you call length or width. We simply use the smaller of the two dimensions to determine the largest square frame that will fit.

The fan diameter is only used to verify that the frame clears the fan opening. It's especially important on condensers with a raised fan grille, where the frame may rest against the grille instead of the top panel.

Remember, the Shade extends 20 inches beyond the frame, so once you've selected the largest square that fits, you'll have excellent shade coverage over the cooling coils and intake louvers—the areas where shade provides the greatest benefit.

AC Shade Size Calculator

If your fan is raised/domed, measure the widest point.
Rule used: We recommend the largest even AC size that fits within your smaller outer top dimension. Inside opening is 2" smaller than the AC model size.

Step 2

Pick the Biggest Square Frame That Fits

AC Shade sizes are based on the square frame.

The fabric canopy extends beyond the frame to create shade, but the frame is the part that sits on top of your condenser.

Use your smaller top measurement and choose the largest AC Shade size that does not exceed that number.

Quick examples

If your top measures 34" x 37"

→ the biggest square frame that fits is 34"

→ choose AC34

If your top measures 30.5" x 32"

→ the biggest even square frame that fits is 30"

→ choose AC30

If your top measures 27" x 37"

→ the biggest even square frame that fits is 26"

→ choose AC26

Do not round up.

When in doubt, choose the smaller size or contact us with photos.

Available sizes

AC20, AC22, AC24, AC26, AC28, AC30, AC32, AC34, AC36

Step 3

Check the Fan Grille

For most flat fan grilles, you can skip this step.

If your fan grille is raised or domed, make sure it fits inside the AC Shade opening.

The inside opening is always 2" smaller than the model size.

Examples:

AC26 frame → 24" opening

AC30 frame → 28" opening

AC34 frame → 32" opening

If your raised/domed fan grille is larger than the opening, or very close to it, send us a top-down photo before ordering.

Step 3

Double-Check the Fan

If your fan grille is flat, slight overlap is okay.

If your fan grille is raised or domed, make sure:

Fan/Dome Diameter ≤ (Model Size − 2″)

Example:
AC28 → opening is 26″
As long as your dome is 26″ or smaller, you’re good.
