Review Senville Ductless Mini Split Air Conditioner Heat Pump
Senville Mini Split units are some of the more popular heat pumps available.

They are very popular with the DIY crowd since they come with everything needed for an install, except the electrical AC wiring.

I recently installed a 9,000 BTU 230 Volt unit a year ago so thought I would post a review of it.

I order the kit from Amazon and it came in three boxes.

The boxes came with the line-set, inside and outside units, along with the control wires and remote.


  • Perfect for a Do-It-Yourself Type Person
  • Kit Comes with everything Needed Except Electrical and Tools
  • Comes Charged with Refrigerant

The Senville is a DIY Mini Split kit so can be installed by a home owner or HVAC company.

Then installation is not hard for a handy person but may not be for everyone.

There is three main components of any mini split with the inside blower, outside condenser and line-set.

The outside condenser needs to have AC wring run to it from a breaker along with control wires to the inside unit.

The outside unit with have the number 1, 2, 3 which go to the inside unit. The labels L1 and L2 is for the 230 volts

The inside unit needs to be mounted on a wall and the line-set run between the two units.

This requires drilling a 3 inch hole in the wall for the line-set to be run between them.

It took roughly 3-4 hours for me to install the unit.

Here is a video I made of the install


  • Very Quiet
  • Heats and Cools
  • Low Operating Cost

The Senville makes very little noise with the only noise from the inside is the fan motor spinning to blow out air.

Most all mini split unit will be quiet to operate and one of the advantage of installing one.

It comes with a remote control that has all the functions such as temperature, fan only, on/off, and more.

The cost to operate the unit is surprisingly low since it has such a good efficiency SEER rating.

The SEER rating for the unit I received was 23 SEER which is very good number.

The SEER rating is how efficient the unit operates, higher the number the better.

The average home air conditioner from 10 years ago had a 12-14 SEER rating.

All mini splits are notoriously low-cost to operate with good SEER rating but the Senville I received currently has the highest SEER rating.

For example I have also installed many Pioneer and Mrcool units with the Pioneer having a SEER raring of 17-19 and Mr Cool at 17.5.

Any SEER number over 17 is a good number but the Senville unit currently has the highest I have seen.

After installing and using the Senville 9000 BTU mini split for a year I can say it is a good unit.

It cools a room addition nicely that is roughly 600 square feet.

They have bigger units with sizes ranging from 9000 BTU – 36000 BTU.

The unit runs almost silent and except for the door opening and air blowing out can almost not be heard at times.

The cost to operate it is also low and much cheaper than a window unit or big whole house unit.

During the summer it cools the space very well.

The winter months it also heats very well and is a very good fit for the American south west climate I live in.

So far, the Senville has not disappointed and has been working very nicely. I will update this post if anything changes.

As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure an adapter is a good fit for you.

    Be aware, no warranty if DIY, not difficult to do the DIY even the vacuum the lines but min support/warranty. Near impossible to get a HVAC tech to install/service a unit they do not sell you for $$$$ markup, therefore no warranty


    I was very impressed with the video, I see the only difference I have is my house is a 60s early 60s models home with a ranch-style brick out of a wall so it’ll be a little harder to make the holes but overall the video was a tremendous help! I didn’t realize I would have to buy the pump and the gauges but like you said that’s a mere drop in the bucket when you’re looking at spending hundreds even up to $1,000 for somebody to install a unit for you especially when you have a mechanical engineering degree like myself, this should not be hard at all but doing it alone with a couple steel rods in my back may slow me down a bit and I’m pretty much a stickler for perfection, so overall, I believe that I can do this and I appreciate the opportunity and thank you so much for offering this video as it is a great assistance to the homeowner and a handyman. You are absolutely right anybody would more than common Sense can install a unit like this as I’ve been through the gamut with a twelve-year-old short “TRANE” WITH A SEER 12,, so, do unit I have now that is no longer functioning I hope we’ll have enough copper piping to buy a couple fittings if nothing else cuz I’ll be damned if I’m going to give it away for paying $6,000 for a train but it was 3 months out of warranty of being 12 years old and it’s a SEER 12 unit. Thanks again, and I look forward to putting in my own unit course I will have some backup hopefully but you know how it is with friends you need them when you need them for when you need them there never can be found!! thank you for taking the time and efforts I’m making this video is it brought things in the clarity!

    I had never heard of this brand before senville, but it appears to be on the forefront of the up-and-coming units in the future. Thanks again.

    Hi I recently just had these installed but the heat option doesn’t work. On heat mode nothing comes out and it eventually gives a p6 error which is not in the manual and on cool mode if I go above 72 nothing comes out. Do you know why this is happening?? They work great for cooling but just can’t seem to get the heat going.

    Thank you

      Adam, I am having the exact same issue. Did you finally get the heat working? I have called technical support and had to leave a message but so far, not return call.
