Will a 4 ton york unit be overkill for 3000 sq ft house? House was built in the 90's.

Thanks

+1.

I'd say, off the top of my head, probably not. You might even need more. Where do you live?

The house was built in 1999.

Here is the information on the unit that is currently hooked up.

Manufacture - Heil
On the sticker it noted two model numbers: ACS036A2C1 and FBA036GC1. Serial number is L984268319.

Anyone know what size unit I currently have?
Thanks

You really need to do a manual J. Mine house was built in 1937, has no insulation in the walls, double pane windows, air leaks sealed, 850sqft, 1700 if you include the basement, so a 2 ton works fine for mine. 1.5 was the min, 2.5 was max that would work, so hard to say.

You have a 3-ton unit. The "036" is MBH (1000s of Btuhs) and is standard nomenclature for most AC manufacturers - a ton is 12,000 Btuh, or 12 MBH - so divide 36/12 = 3 tons. A 3.5-ton unit would be "042", a 4-ton unit would be "048", etc.
