Mini Split suggestions

[JDUB]

I'm going to put one in our garage. My son is turning it into a garage/gym. In terms of tonnage, is there a formula you need to apply in order to know what you need?

I believe it’s 1 ton per 400sq. ft.

My mom had a screened-in porch that she converted into a sunroom. It has a vaulted ceiling and windows on 2 sides. She added a 1.5 ton mini split and it works great.

Mitsubishi is the leader in mini splits. Fujitsu and Daikin are second and then everyone else. ( I used to work for a large HVAC dealer), I will real quick address Mr. Cool , I have seen a few of them. horrible warranty service and even worse on parts supplies. The warranty also does not transfer like a regular HVAC unit. Not that Mr. Cool was doing anything related to warranty help for the customer. Trying to buy parts from Mr. Cool was an exorcise in wasting time. Mr. cool uses parts from other companies which was good due to being able to cross over the numbers and buy parts elsewhere. Mr. Cool uses the cheapest metal fabrication you have ever seen.( 2 year old unit with rust thru ) Warranty would not cover the unit rusting out. The Mr. Cool claim to fame is they sell direct to the homeowner with no middleman and no dealer support. They have a location in Kentucky and Ohio.

1 ton per 400 square feet as above is the base formula. Then consider insulation, windows and sun load.

400 to 600 hundred square feet per ton is the rule of thumb. But you have to consider insulation windows ect.

Insulation is the biggest factor

Dave I’m sure your on me with this is these big box companies are just making it hard on us small guys! Also they give out a lot of false info and don’t care about their customers.

Mr Cool has some great DIY products and some even come with pre-charged line sets. Mitzu has some great products too but they are professional install.
If you are a do it yourself guy, Mr Cool is perfect. If not, DR COOL can help.

Also Dave am I missing something the only way you use to be able to buy equipment pre charged is with a epa license. Has that changed?

Don't use SFT per Ton!!!!
Get a "Manual J" calculation.

Mr Cool is selling them online. I don't know if a charged line set qualifies or not for an EPA card. That is a good question.
