TOSOT 9,000 BTU Mini-Split Air Conditioner, Wifi Enabled Ductless Inverter Split System AC Unit Heating System, Compatible with Alexa - 20 SEER2 115V

I finally finished installing this mini-split in my home (DIY). In hindsight, the installation is not that difficult, but I will caution any ambitious DIY'ers that if you've never installed one before, watch several Youtube videos of people installing similar mini-splits and determine your comfort level doing the install, because the included instructions aren't great.So far, the Tosot unit has been excellent. The indoor unit's fan is very quiet, has maintained a consistent temperature (currently using for heat, but look forward to cooling in the summer). The outdoor condenser unit is also surprisingly quiet. For those that don't know, this is basically a rebranded Gree unit, so it uses the Gree smartphone app which seems to work well (if you choose to connect your unit to WiFi). While I'm thankful it has the onboard temp display that is easy to read on the wall unit, I'm very glad you can easily turn off the LED display using the remote control. Otherwise, it lights up my whole bedroom at night. There are no other obnoxious LEDs on the unit to worry about in a dark room.A few tips for those that plan to DIY this install. You'll need an open-ended torque wrench or crow's feet adapters for a standard torque wrench. I had a hell of a time trying to figure out ahead of time what size crow feet I would need to tighten the nuts on the coolant lines. The instructions have the wrong nut sizes called out in their torque table. I believe I ended up using the 3/4" and 7/8" crow feet, but they don't fit the nuts very well. I think the nuts might be metric. Also, don't forget to purchase the correct R134A adapter to connect your vacuum pump.My three favorite YouTube videos that I referenced for my install were:"Budget Mini Split Installation for Beginners! w/ Vacuum Pump and Gauges" from DIY Solar Power with Will Prowse"DIY Mini Split Install - All the Things Nobody Shows You" from LRN2DIYAnd watch LRN2DIY's follow up video "DIY Mini Split Install: 3 Regrets After 1 Year of Use"

I bought a 12,000 BTU for the kitchen/office and then a 9,000 BTU unit for the bedroom, they were easy to install, and have been working silently and perfectly for heat and cool.I just ordered a 3rd one last night, 9,000 BTU for the front room.You DO need a few things to install these yourself but they are half the price of the "mr cool" units so you still save a few hundred bucks.You will need;A Vacuum pump with gage set (about $100)An open end torque wrench (about $50)A hose adaptor for connecting the vac pump (about $8)Nylog sealant (about $13)Here is what I bought to use;VIVOHOME 110V 1/4 HP 3.5CFM Single Stage Rotary Vane Air Vacuum Pump and AC Manifold Gauge SetVANPO Adjustable Torque Wrench, 5-45 Ft.lb/7-61 Nm, 38MM Open End Torque Wrench, 3/8 Inch Drive Torque Wrench with Interchangeable Jaw & Ratchet Head for HVACR410a Charging Vacuum Port Adapter Brass Converter with Thimble 5/16 Inch Female Quick Coupler to 1/4 Inch Male Flare for Mini Split System Air Conditioner HVAC Refrigeration ServiceRT201B Nylog Gasket/Thread Sealant, 30 ml (1 Pack)If you are doing the wiring yourself like I did- you need a 12/2 with ground copper cable, a disconnect box and a breaker.After installing the head unit indoors and the condensor outside you connect the copper linesets, drain hose and communication cable which come out thru the wall from the head unit to the condensor, use a small amount of the Nylog sealant just on the copper flares' seating surface NOT on the screw threads.I used a short piece of 3" PVC drain pipe to cleanly go thru the wall.After connecting the linesets you need to torque the flare nuts on them to the specs in the manual, this is a VERY important step- too loose or too tight can cause leaks, get that tight to the specs and you won't have a leak problem.You need to connect the vaccum pump to the service port using the adaptor as the hoses are different, there are videos showing how on youtube, it's easy enough, let the pump run, a half hour is fine, close the service port valve and then shut the pump off and remove it.Now you use an allen wrench to open the two valves on the condensor's brass fittings, and the refrigerant enters the lines, now it's ready to go! The instruction booklet helps, youtube videos will help get it done easily- just make sure not to kink the copper lines, unroll and flex them gently into shape and position, TORQUE the fittings correctly, vacuum pump a half hour, and it's done, very simple.So I spent about $175 for the pump, adaptor etc but I used it for 2 units and now will be using it for a 3rd, so it's more cost effective divided over multiple units- even buying those to install one unit is a lot cheaper than mr cool which wants around $1299 and that still demands you use a torque wrench to tighten the flare nuts.For youtube videos search for these excellent general guides on a few types of these units such as mr cool and others, ( Tosot also has a youtube video on the exact product too which is also helpful)How To Vacuum Down a Mini Split with Analog Manifold GaugesThis MINI-Split AC System Changed My Life | Learn How To Install One YourselfHow To Install a Mini Split Line Set - R410a Flaring Guide & Torque Settings Using NylogOne thing to keep in mind is, ALL of these mini splits are basically the same other than slight cosmetic differences- they are manufactured by Gree global corporation at the same plant regardless of "brand" name slapped on the outside.According to the Nikkei newspaper, Gree’s global market share of residential air conditioners reached 20.6% in 2018, ranking No.1 in the world for 14 years.Gree has established 126 research institutions, 1,045 laboratories, 1 academician workstation (motor and control), one national key laboratory, one national engineering research center, one national industrial design center, one national recognized enterprise technology center, and one robotics engineering technology research center.So, these Tosot units should give years of dependable service, and the manufacturer is well established with a long record of many types of appliances and industrial units.EDIT 14 months later, still all good, but I noticed due to trump tariffs the price went up $63, partially hidden with a new $25 'delivery fee' I didn't pay before.

Installation was easy, and it works great!

This is a great little unit once I got all the pieces and got it installed. The first delivery came with only the indoor unit and omitted the condensing unit. I had to return the indoor unit and reorder delaying me for weeks. I installed the unit over three partial days. Because it is 120 Volts and only pulls about 12 amps, I was able to tie it in to an existing lighting circuit. This unit is of good quality but the instructions are only fair. That is completely remedied by a great You tube video from LRN2DIY.com. He does a complete install with detailed instructions. This unit is not really designed for DIY so you have to have a vacuum pump and gauges. This equipment is available on Amazon for less than $200 and the video from LRN2DIY shows you how to do it and makes it really easy. I would buy this unit again!

This item is GARBAGE. It won't even take a vaccum test. DO NOT BUY, when brought to their attention they avoid or look the other way. I had a repairman come out to install the unit..he tried to run a vaccum check ,it wouldn't,it was leaking through a bad valve. The repairman also stated the tubing is incorrect. Its supposed to be 1/2 and 1/4 inch tubing. They was to loose in the flange tool to hold. He stated in his 30yrs he's never seen this.This has to be overseas copper.They dont use our system in measure. He couldn't even do a new flange or vaccum.
