I finally got someone to come out and vacuum the lines. He did a good job, tested it with nitrogen first and charged me $150. That was better than buying equipment and having it sit around. The unit is now running, we’ll see how well it works over the next few days!

Definitely worth the 150 bucks, especially since he pressure tested it. Anxious to see how it works for you.

Thats what I paid too
I have a working relationship with an HVAC company so they were fine with working on a unit I purchased and installed.
Warranty work- lets hope i don't need to find out!!

It seems to be working well. The temp outside yesterday was 8-10f and I had the thermostat set for 68. It held at that just fine. There is no vibration that I can hear in the garage and the indoor unit is almost noiseless. I think I will be very happy with this

Wow, interesting. Im in the Bancroft area. I installed an 18000 BTU Senville unit above my garage in a 1000 sq ft loft. To supplement my wood stove . I did the full install. Put the lineset in the wall cavity. Mounted the outside unit on the brackets under my 2nd storey deck. Couldn't get anyone out to evacuate and charge, so after much investigation and YouTube took the gamble, bought a gauge set and evac pump just for this one job. Worked perfect. 5 yrs later works perfectly. [emoji106][emoji106]

That looks great! I’m finishing my loft in a very similar way. I was very tempted to buy the equipment and do it, really looks fairly simple as long as you don’t have a small leak. How is your unit performing when it’s very cold out and what is it like for ac in the summer? Any idea of the cost?

We generally use it as supplemental heat. But when ever I use it I'm impressed with its performance. The upper loft is 1,000 sq ft. open space. The AC works really well. We were very thorough insulating. 2" closed cell and then fiber glass. I think the insulation is the key. So far 5 yrs, I assume no leaks, system works as it should. I used the pre flared fittings.

I am going through this right now and I am doing this in WA state. Yes, it is crazy that all circuits in a garage now have to be GFCI protected, however, WA has put an exemption in place until 2023 for HVAC equipment giving manufacturers some time to come up with the proper breakers to be compatible.
In my case, I have a Square D Homeline panel in the garage and I am installing a 12k Bosch mini split that requires a 15A 2P breaker. Square D does not make a GFCI 15A 2P breaker, the smallest they make is a 20A. Good thing there is the exemption as I wouldn't be able to pass inspection otherwise.

Hey Glenn I have a question about your indoor unit.
I helped a buddy install one just like yours, and there's no display on the unit showing the set temperature.
Does yours show the set temperature on the indoor unit?��

No it doesn’t show the temp on the unit. The display on the remote shows it but it doesn’t seem accurate I have a small digital thermometer that I leave by the unit. I find setting the temp at 75 will make the room about 70. The good part of that is if I use the low setpoint of 62 when not there it will be in the 50’s in the room so less energy used

I’m pretty sure the display on the remote for that unit shows the setpoint only, not the actual room temperature at the remote’s location or at the unit.
Set your thermometer by your unit’s return air intake to see the temperature it is reading.
That’s where I have the thermometer, it’s sitting on the unit right above the sensor. It seems like there is a 5 degree difference between the set point and the actual temp at the unit. I wondered if there is a way to recalibrate it but I can just go by the actual temp as well.

Some units can be reprogrammed to compensate for temperature differences.
5*F between setpoint and general room temperature is not unusual though, depending on a few factors..

Well, I have the upstairs finished and I would like to say that the air conditioning is incredible. Takes very little time in this current hot and humid spell we are having to make it very comfortable inside. I’m very happy with this unit!
Below are a couple of photos of the inside. I just need to decide how I’m going to finish the stairs going up from the garage. Right now they are just 2x10’s with no risers

I have installed many mini splits, I did HVAC for a living. As for vibration, they really don't! I doubt you would have noticed it if it were mounted to the house.
I installed a mini split at a small manufacturing shop years ago. We mounted the outdoor unit in the shop as we needed air conditioning all year around. It was for a small computer server room. The only handy place to mount the outdoor unit was right over the shop foreman's office door. I thought he was going to have a fit! He was concerned about the noise and vibration. It ended up with a meeting of the managers and I assured him he wouldn't even notice the unit running with all the other shop noise in he back ground. I told him I would move it for free if it was and issue. It never was. I went back a few weeks after the install and talked to him. He said he didn't even notice it.

My Brother in law had one installed on the wall and when I was visiting I slept in the basement in a bedroom adjacent to where the outside unit was , I could here the droning sound constantly…he had it moved soon after that.
Mine is very quiet. I do have 2x6 walls and glass insulation. The indoor unit is in the second level but I don’t hear it on the lower level either. I actually have to walk up close to the outside unit sometimes to see if it’s running.
