  • 21.5 SEER rating ENERGY STAR certified: estimated national average annual operating cooling cost is 70 USD based on AHRI certificate #9150138
  • Package includes: stylishly designed interior white wall-mount air handler with LED display; exterior pre-charged condenser with special golden anti-corrosive coating coils; wireless remote control for customizable airflow and temperature adjustment; 25 ft. complete kit
  • 25 ft. kit includes: copper tubing with insulation and nuts, control wire, 6 ft. drain hose, wall sleeve, wall sleeve cover and tape
  • Electroplated coils: the electroplated hydrophilic coils improve heating efficiency by accelerating the defrosting process; the unique anti-corrosive coating on the coils also aids in withstanding the effects of salty air, rain and other corrosive elements by allowing contaminated water on the coils to run off more quickly, reducing the corrosive effect to the coils; heat exchange performance is much longer lasting
  • Low ambient operation: a special built-in low ambient kit can be used in temperatures as low as 5°F for cooling operation, useful for users who need to maintain cooling during winter
  • Refrigerant leak detection: with this new technology, the system will alarm when a refrigerant leak is detected
  • Dual sensor fixed or remote: by switching to remote sensor and keeping the remote close to you, you tell the air conditioner to set the temperature from wherever the remote happens to be, this counteracts the tendency for the air conditioner to stop cooling or heating because the air around the unit has reached its set temperature (switches off after period of inactivity to preserve battery life)
  • HEPA filter included (1): a HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites and tobacco smoke
  • 2-direction air vane technology: in cooling mode the air vane opens counterclockwise to direct air horizontally, allowing for an even cooling effect; in heating mode the air vane opens clockwise, directing air downward, this time for a uniform heating effect
  • Built-in electronic diagnostic: monitoring some abnormal operations or parts failures, microcomputer of the air conditioner will switch off and protect the system automatically; meanwhile, the error or protection code will be displayed on the indoor unit
  • Outdoor pan heater: a heating belt is fitted on the base plate of the outdoor unit to avoid accumulation of rain, snow or water on the base plate
  • Dual washable filters: a good air conditioner should not only take care of the temperature in your home but also the quality of the air you breathe; the system aids in removing most of the pollen dust, smoke and other microscopic airborne particles that by latest thinking contribute to respiratory problems like asthma and hay fever
  • Self-cleaning: by pressing clean on the remote control, it automatically cleans the evaporator to aid in reducing buildup of bacteria and keeps the air fresh
  • Sleep mode: in sleep mode, the unit automatically decreases the heating or increases the cooling by 1° per hour for the first 2 hours of use, then holds the temperature steady for 5 hours before ceasing
  • Low noise airflow system: without decreasing the airflow volume and capacity output, the large-diameter cross flow fan can bring down the indoor unit noise level by lowering the fan speed
  • Anti-cold draft: if the unit is turned on in heat mode when the ambient temperature is low, it will warm up prior to fan operation to prevent cold air in heating mode
  • Louver position memory: the set louver position is stored in memory by the microcomputer and the louver returns to the stored position when the next operation is performed
  • Turbo mode: this function enables the unit to reach the preset temperature in the shortest time

I bought a 2-head Senville 22 SER unit last month and came to the conclusion it makes sense to install it myself versus paying an installer. I too am in Los Angeles.

This works if you're handy since you'll probably do a better job. Doing things like a nitrogen pressure test, which aren't stated in the manual, is a good practice that many installers will skip unless it's explicitly stated in the manual like in some Mitsubishi units. This practice makes sense for heat pump R410A units which will see upwards of 450 psi on the head when in heat pump mode. But expect to spend $500-$700 on tools if you want to do it right.

Edit: if you want me to comment more on the tools I went with, let me know.
Edit Edit: As promised, I posted my tools breakdown reply on #99 of this thread, but I'm also going to post it below too. If this angers the mods then please remove post #99.



Everyone can decide what you need for your install versus others, but here's the tools that I bought for mine:


Nitrogen Tank w/ Regulator (got on Craigslist)1 $ 100.00
Appion CTEE14 MegaSeal Low-Loss Charging T-Fitting - 1/4'1 $ 49.94
Appion MGAVCR Mega Flow Vacuum Rated Valve Core Removal Tool – 5/16" System Connection1 $ 48.48
CPS VG200: Vacuum Micron Gauge with Digital LCD Display1 $ 146.21
Refrigeration Technologies RT201B Nylog Gasket/Thread Sealant1 $ 10.25
Yellow Jacket 42004 Series 41 Manifold with 3-1/8" Gauge, psi, R-22/404A/410A1 $ 112.29
Yellow Jacket 19173 R-410 5/16" to 1/4" coupler w/ schrader valve.1 $ 14.26
CPS Pro-Set R410A Flare Gauge1 $ 19.81
CPS BLACKMAX BFT850 Ultra-Lightweight R-410A Clutch-Type Ecentric Flaring Tool1 $ 130.03
Reed Tool DEBO Pencil Shape Deburring Tool for Copper1$11.68
RIDGID 32975 Model 103 Close Quarters Tubing Cutter, 1/8-inch to 5/8-inch Tube Cutter , Silver , Small1$12.67
Johnsen's 6915 Vacuum Pump Oil - 12 oz.1 $ 9.79
PITTSBURGH AUTOMOTIVE 3 CFM Two Stage Vacuum Pump1 $ 149.99
PITTSBURGH 3/8 In. Metric Crowfoot Wrench Set, 7 Pc.1 $ 9.99

For mine, it was a total of $825-ish, with it being more like $900 after tax. But I bought multiple things that most people don't need to buy, marked in italics, so you can save a lot of money skipping these. These optional tools represent an additional $372.61 ($400.55 after tax, at least where I live) you can eliminate about 50% from the tools budget.

First and foremost, don't attempt to work with electrical or HVAC unless you're pretty comfortable with DIY projects.

The Nitrogen tank is optional for pressure testing. Some say if you can pull a good vacuum and let it sit for a while that is "good enough" and most company's instructions exclude this from the installation instructions. But it's worth considering because when running R-410A in heat pump mode, you'll get high pressure across your head side of the loop. This makes sense because the high-pressure side = heat. So in my head it made sense you'd want to do a pressurization test and a vacuum down test, since one is pushing apart the fittings (pressure) and the other is sucking them together (vacuum). Since the fittings will all be exposed to both types of pressures it makes sense for me. Follow Dakine or Mitsubishi installation manual instructions for nitrogen pressure testing if you opt to do it. Note that most professional installers WILL SKIP THIS unless it's a unit that requires it (think Mitsubishi) and the installer is one of their "diamond" approved installers or whatever.

Secondly, I bought a flaring tool because I had a 2-head system and cut the tubing to fit the installation and make it more tidy. This is optional and I do not recommend it unless you know what you're doing. It also saves money to skip this. Before cutting, you need to make sure your run or runs have the required length to prevent overcharging the system. If you have a single head unit and end up cutting the tubes to 1/2 the length you may have too much refrigerant in the linesets. Refer to your manual or talk to the company before you decide to do this. And if you decide to do it anyways, yes it must be a HVAC specific flaring tool. Get one with the clutch system to prevent overtightening the flare press and make it foolproof. R-410A runs at too high of pressures to get away with subpar flares. Deciding to just accept the standard length of the copper tubing eliminates the costs associated with the Flaring tool, flaring gauge, deburring tool, and pipe cutting tool.

As for the rest, you do not NEED a digital micron gauge, many just use their normal gauge set's low pressure side gage and watch to see if the needle moves. This will also work. Again I wanted to go with professional duty equipment to get an install I'm 100% confident in. That way if the thing dies in a few years I won't have wonder in the back of my mind whether I screwed up the install. I know 100% my install was perfect. I went with the Yellow Jacket brand gauges, although you could in theory just get the low side gauge, hose, and valve if you're just pulling vacuum and save some money. I'm sure the garden variety chinesium brand gauges are probably perfectly fine for a solo install and will cut the cost in half for them.

The Appion Schrader core removal tool and the t-valve are totally optional too. You'd have to do some youtubing to see how they're used, but here's a great video which shows essentially the same setup I bought: https://www.youtube.com/watch?v=81EeY7SFYJc

But you can skip those tools and just use the Yellow Jacket 5/16" to 1/4" adapter and be just fine without them. Your pressure drawdown will just take a bit longer since you're going through the Schrader valve, and you'll loose a tiny bit of refrigerant before the schrader valve closes. Skipping these tools will save you $130-$140.

For the vacuum pump I went with a harbor freight 3CFM rated 2-stage vacuum pump. I believe it's rated for sub-30 microns of vacuum which is great, and a review on their site showed a guy pulling 13 microns if I recall correctly. To put this into perspective most manufacturers suggest pulling below 500 microns before charging the system. This is slightly overkill but it works for me.

Lastly I already have a torque wrench but you can get them dirt cheap from harbor freight, and I bought some crowfoot wrenches to use with my torque wrench to torque the bolts to the manufacturer's specifications. Will it really matter if you don't do it to spec? I don't know but I'm not finding out.

Then beyond all of this you'll have to run some 220-240v and have a disconnect box by your run. If you're not a confident DIY'er don't go for this, but if you are then just watch plenty of videos of installations, follow the instructions, and you'll be fine.
Having a precharged condenser is no big deal; I believe all mini splits are sold that way. In fact, large (residential) ducted A/Cs ship that way as well. But to DIY this, you'll need a vacuum pump to evacuate the air from the line set before you release the refrigerant. I have done a couple of installs of mini splits (not this brand), and it's not that difficult, but you do need to understand exactly what you're doing. Do some reading before you decide to buy this.
Taking a quick stab:

Pros-
No duct work is obvious.
On demand which can save heating/cooling bill.
More precise temperature control "zones".

Cons-
The zones play as double edge sword, when moving in or out the heated/air conditioned space takes some getting used to.
The indoor unit hangs on the wall compare to just a register, so the wall is more or less occupied.
Have to run additional electricity to both in door and outdoor units and the tubes from the indoor unit to the outdoor unit.
More filters to clean.

I'd really love to put one of these in the nook area of my kitchen that gets the hottest -where we eat dinner - but I have no 220 anywhere near it. Not going to spend more on the electrical work then I would on this unit.

These things work but it's not going to heat your place to 80 when it's 0 outside. They are good for maybe a 40 degree temp difference inside and out.

Same boat. Local quotes want $4k when the AC is <$1k.

4k?! Yikes. Got quoted about 10% of that in the Austin area. Crazy that it would be that different.

Quote from ToolDeals :
Mr Cool comes pre-charged, whereas and according to reviews, you will need some extra tools and supplies to install this one yourself.... like a vacuum pump, freon, electrical requirements, outside mounting brackets, etc. Some installations are reasonably easy, but others can get very expensive and time consuming.

PS: The DuctlessAire units sold on Amazon say 'pre-charged lines."

Hold up, lots of misinformation here. You're going to be installing the Mr. Cool exactly the same way as every other unit out there. The difference is the refrigerant is in the condenser unit ready to go in the conventional units (like this one) vs the Mr cool units having it in the lineset. Know that you also cannot cut to length with the Mr. Cool either making some people getting creative with the excess line length that causes problems a lot of times because if you're going to coil it up, it needs to sit horizontal. At the end, if you install them yourself, the conventional unit will run you about $250 or so for a professional to purge the lines with nitrogen, vacuum it down below the magical 500 micron level, check for leaks, then release the refrigerant.

Curious about this. Been quoted 5k for pro installation of a mini split in the garage. Need it for my server rack as it gets crazy hot in there but I seriously dont have 5k laying around and I'm not handy.

Garage is 22x20x9 with thick carpeted floor but not the best sealing or insulation.

Thinking about getting a unit now and installing it later.

Is this worth it? If so, what size? I have an alert for mini split and haven't seen a deal in a long time.

Most A/C companies won't want to get involved in installing customer-purchased equipment. HVAC is a very closed industry, and unless you can find a pro who's willing to do some side work, you're probably not going to save that much vs. purchasing the system directly from the installer; in addition, you'll get a warranty for the installation, for whatever that's worth. I do see that Home Depot offers a referral service for installation of this A/C, so that might be a better bet than just calling A/C installers at random.

Quote from luddite_cyborg :
I need to do some research, maybe someone with the know-how can weigh in:
Comparing the 9000 to 12000 BTU models, the 12000 is quieter and has a variable speed inverter for the heat pump (for $80 more).
I'd prefer the 12000 model but it's oversized for my basement room (~300 sq ft). How bad of an idea is it to install the oversized 12000 BTU model? Can I expect freezing coils, etc. like with a standard window AC?

These are variable speeds so you're fine if you oversize. The only downside is your potentially throwing money away since your unit won't reach 100% usage.

you might want to check the outside facing wall of the garage for insulation as not all builds put insulating in the outer wall of the garage.

A dehumidifier is about the opposite of an AC. Similar principle, but the dehumidifier produces heat in addition to removing moisture from the air. To dehumidify in warm months, run your AC more. In cold months, run the dehumidifier.

What, no. An ac is essentially a dehumidifier. You can run a dehumidifier with an AC if you want. I think you're thinking of a humidifier, which adds moisture, great for dry winters.

Is the 18,000 something that can work to cool a garage? Two car and I am aware of air escaping from the door and lack of insulation. But I am in AZ and want to put a gym in my garage.
18K BTU should be more than enough for a garage, but I'd insulate the door with sheet foam (if it's a metal door), make sure you have good rubber on the bottom and add some where the top of the door touches the wall when it's closed, and as someone else mentioned, check the outside wall for insulation (assuming it's wood and not concrete).

240v wiring typically only serves a single appliance in your home, not like 120v where many outlets and lights or what have you reside on the same circuit. Unless you had an unused range or dryer or something plug right there to repurpose, you'd need to add a new circuit anyways. Even if you did have a 240v circuit nearby, like say you were putting this right next to the electric range, you would not be able to simply tap into that range's circuit. You'd still need a complete new one.

That said, as long as there is room in the panel, adding a circuit probably doesn't cost as much as you think, labor wise at least. Material cost is another matter as wiring has gotten up there like lumber lately though. Even being very mindful on overall spent, I'd be far more concerned with install cost of the unit itself and the condensate drain routing (if it's not on exterior wall) than getting power to it.

Keep in mind, this has to be installed by a licensed HVAC technician to maintain warranty

If you're looking to do a DIY install and care about the warranty, there are other DIY models on the market that come pre-charged.

keep looking. i wanted one in my garage for years. when i first started looking, i was getting quotes about the same as one for the house. last year, i started looking again. one place wanted 15k!!!!! i was ready to hire off one quote for 3300, plus wiring(another 400). then one local place quoted 2300 installed, including tt&l, and wiring. they came the next day, and about 3 hours later i had a cool garage. it was a daikin 12000 unit
