good idea. planning to do the same thing, will be great if you will give us some details about the coil description, how do you do the calculations of the gas expending?

I have one very much like this. It also has a rating of 1 H.P. - any idea what the equivalent in BTUs is?

 

[Dr. Dendrostein]

I know 1/2hp is 5000btu so 1 hp 10,000-12,000btu?

@Mark Gray On choosing a mini-split. If budget permits go with Mitsubishi brand, ahead of the competition. Warranties great. But for a 1100 square foot home materials alone apprx. $6000-$9000. Depends where bought. But saving on electricity big.


@Mark Gray

In September I am taking a road trip but I am going to see an old high school buddy I hope I can buy 2 mini splits from him whole sale. One with 3 for upstairs and one with 2 for downstairs I will do the downstairs but since I fell 20 years ago I really hate heights lol

 

[Dr. Dendrostein]

Try to get factory manuals for future use.

 

[Dr. Dendrostein]

If I had all materials, 2- 3hr project. Here's what's also needed

Flare fittings
Pierce valves
Silver bearing solder
Map gas
Insulation

I won't get into wiring, every unit different. Also charging.
Did this for ideas.

Waiting for temp. Control

 

[Dr. Dendrostein]

Soldered 3/8 copper after cap tube.
Then suction pipe. Then flared them
