Well, I finally bit the bullet and purchased a mini split. My 10,000 btu portable ac unit just can’t keep up when it is 90 degrees or higher out.

If anyone is looking for something similar, there is a great price on Overstock.com for this unit with a 14% off coupon today…

https://www.overstock.com/Home-Garden/Advantage-3rd-Gen-18-000-BTU-1.5-Ton-Ductless-Mini-Split-Air-Conditioner-and-Heat-Pump-230-Volt-60Hz-White/28111048/product.html?TID=Cart:Link:ProductLink:CartItems

This coupon along with purchasing $750 worth of their online gift cards from Raise.com @ a 3.5% discount for $713.75 gets the system shipped to your door for $787.66 out of pocket after tax.

The unit has a 19 SEER rating and is Wifi enabled so you can control remotely. I will have to have an electrician hook up the additional 220v line i am running and HVAC tech to charge the system.

Just thought i would share if anyone else was in the same boat.

My neighbor is building a new house and he will no longer need his 18000 btu window air conditioner. So next summer I will have air in the garage. He said I could have it off free. I think hanging on one more hot season can be done.

Looks like the system comes charged.

Is it not just a matter of pre charged lines?

I have the mr cool 24k diy unit in my shop. The diy system does come pre charged with 16’ or 25’ line set.
I had pro A/C company give me an estimate before i went with the DIY system. So size of unit, and placement was picked by someone who new what they were doing. Fully insulated shop, my system is working great. Just turned one year old.

we install a lot of them in garages so folks can keep their car cool, usually buy them on line, and install, then have an ac contractor ensure charge is completes and unit is functioning as should be. thats just us though, want it to meet the manufacturer warranty

There seem to be several different brands, but they all look alike. Are these built in the same factory? Maybe to slightly different specs? Which brand should a guy look at? Not looking at Mitsubishi as they are so much more expensive than the others.

I had a Bryant branded system installed in my new home office. The contractor didn’t think the main system would adequately deal with the space. Bryant is a subsidiary of Carrier. As you know, all of these units come from China. The Bryant unit never worked well: it could not cool on the warmest days and was particularly unable to warm the space on cold days (I live in Western PA, so we get high nineties and -10 worst case). I had techs out from three contractors, and had “factory” techs on phone calls diagnosing and advising. No change. The general contractor for the home remodel chose the HVAC contractor who selected the unit and installed it as part of a much larger project.

When my regular HVAC dealer came out to do the annual AC clean/tune/checkup, we talked about the mini-split. They are a high end Carrier dealer. He said they had had it with the Carrier ductless, had given up and went with Fujitsu. I had them rip out the Bryant and replace it with the Fujitsu. Big difference, although we only have been through part of the first AC season and I haven’t tried it in a winter yet. But it’s MUCH better than the Bryant so far. Pretty close to the same nominal specs. The inside head is a bit larger, the compressor/heat pump is about the same size.

One tip. They all have a wireless controller. The wireless controller DOES NOT have a temperature sensor. The unit measures the temp of the incoming air at the head end. Some systems (my Bryant) has an option of a wired controller. That does have a temperature sensor. The Fujitsu as shipped, is not equipped for a wired controller – you can swap main boards to get that option, but it’s expensive. I don’t think the “measure the air at the inlet” is a good system for maintaining comfort where you want it. YMMV.

Received the system on Thursday and installed the exterior mounting brackets, condenser and line cover kit along with the inside unit. Took about 3 hours.

Next is to run another 240v circuit from the panel in by basement out to the unit and hook everything up. I will have an HVAC tech come and vacuum the lines and perform leak tests.

I am very happy with how everything has come together and this will be a welcome addition.

Have your say...
