Hey guys,
Summer is peeking around the corner already, and our new shop is not air conditioned (yet). I'm a pretty firm believer in AC in the shop. Keeps me and the employees happy and comfortable, work quality is better, and we're not wore out near as much by the end of the day.
I am looking for any advice on sizing a unit for the shop. Most of the calculators I have found are for residential houses and a house vs. an industrial condo aren't really apples to apples as far as tonnage of refrigerant required.
We have a 4000 square foot unit (give or take a few feet) with 21 foot ceilings. It is a steel building, insulated OK, not the best, but could be worse. Heat bill (natural gas) is around $180 a month in the coldest months. West Michigan doesn't get too hot compared to like, Arizona, but we get plenty of humidity and 90-100° plus days in late July once the lake heats up and we lose the cooling effect.
One big room aside from the (small) office and the head. I will probably get a window shaker for the office so I don't have to run too much ductwork.
Various online calculators have put me in the 10 ton range, not sure if that is enough? Or too much? My last shop had a 3 ton unit, 2000 sq. feet, and it ran constantly so I know it was undersized. But it did manage to at least hold temp and keep the humidity down, so it wasn't that much under. A 5 ton probably would have been enough.
Sheet metal shop down the street keeps their shop comfy with two 5 ton units, they are at 6000 ft, but lower ceilings.
Ingram's has a 10 ton Daiken for 6k free shipping and comes with the air handler and all, I'm considering going that route.
A friend is an HVAC contractor, so I am going to get his input, but I figured I'd run it by the hive mind. What do you guys have in your shop?
