On 2023-05-19 by InspectApedia DF (mod) - Filter size for York AC model n2ahd14a06c

@Steve,

I'm not sure that that number is the model number as it's a different format than usual - that may be a serial number. Take a look at our York manuals page here:

YORK HVAC AGE, MANUALS, PARTS

where you may find the correct manual. If not, there is also contact information for York to contact them for the filter size also. Often, the filter size will be a readily available size used for many models.

First though would be to check your owner's manual for your unit if you have it.

And if you can give us the model number or if we find the information you ask, we'll add that here.

Interestingly a review of several York HVAC manuals finds that the manufacturer doesn't give air filter sizes - just type. options, perhaps because of variation in cabinet size among models.

Usually we can simply use a tape measure to get the length and width and maximum thickness of the air filter - just open the air handler door to show the filter slot or mounting brackets.

If you've not already found where the air filter mounts on your system:

Watch out: in some HVAC systems there is NO air filter in the air handler itself. Rather the filter may be at a central air return or at multiple air returns.
