A world of difference in comfort and convenience for us and our pets
Size: 18000 BTU
We purchased the Senville SENA-18HF-Z to replace the portable heat pump/AC units we've been using in an outbuilding which houses a 280sf studio and a separate 90sf cattery room (about 3500 cf total). Those portable units, at a cost of about $400-$600 each, would last for about two years running 24/7 before quitting, not to mention having to manually select heat/cool/dehumidifier modes - a real PITA when you're dealing with extreme temperature fluctuations and animal housing. With the price of these mini-splits now so affordable, it was a no-brainer to finally make the leap when one of the portable units died again. We opted to go with Senville over the next closest contender we looked at, Mr. Cool, based on cost, energy efficiency, warranty and length of lineset (16 ft standard, longer available; Mr. Cool only offers 25 ft length). The hardest part of the installation was finding a qualified HVAC person to come out and do the final hookup to qualify for the warranty. Most companies I contacted understandably want to do the whole installation, either with systems they carry or exclusively work on (e.g., Mitsubishi and Daikin). Before pulling the purchasing trigger, I found a company who agreed to do the final portion of the installation with the system we wanted to buy, for $400. While we waited for the Senville to arrive, we ran the new electrical line and quick disconnect box Siemens WN2060U Non-Fused AC Disconnect. We also had to figure out how we were going to circulate the conditioned air into the smaller cattery side of the building, and ended up installing a couple intake fans through an inside window Achla Designs Room-to-Room Minuteman Doorway Fan and an exhaust fan Fan, Room To Room, 8 In through the wall. Our system arrived from So Good to Buy in about 2 weeks, one week earlier than the shipping estimate. Everything we needed was included (except for a 12-4 or 14-4 power cord, which we bought locally but can also buy here MINI SPLIT CABLE 25FT LENGTH), and we installed both the air handler (indoor) and condenser (outdoor) units over two days. The directions aren't great; I think the instructions assume you're an HVAC professional and know what you're doing. There was no wall template for installing the air handler bracket. They use the same directions for several systems and it's not clear what diagrams go with what since they're not keyed by model number. With a little common sense it's not hard to figure out how the units get mounted and what the basic hookups entail. Since the condenser was going to be located on the side of the studio above our parking area, we opted to rent a material lifter to safely hoist it up about 8 feet onto the brackets Outdoor Mounting Bracket for Ductless Mini Split Air Conditioner Heat Pump Systems, Universal, 9000-36000 Btu Condenser we purchased separately. The condenser only weighs about 130 lbs. but the weight is very unevenly distributed and wouldn't have been fun for two people on ladders to deal with. For the final work, our HVAC guy checked the electrical, evacuated lines, hooked everything up, released the refrigerant and checked the system for proper function. He was also prepared to bend the lineset and cut/reflare the lineset ends but didn't have to. Since the Senville needs a minimum of 10 feet of lineset, he opted to leave it as is and coil the remainder behind the outdoor unit. The big moment came when the system was turned on for the first time; we were thrilled when the studio temperature immediately dropped 15 degrees in about 5 minutes! And the cool air was nicely distributed throughout the whole room, even the loft area. There are no controls on the air handler; you must use the remote to make any adjustments. We've installed the remote and its included holder near the entrance. HVAC guy said the actual thermostat is in the air handler, and there's a convenient lighted display of the current room temperature right on the front panel. Countering the worst review here, I've not found the actual room temperature to be different from whatever I've set it to. Also, the condensor may not be the better-known Mitsubishi or Daikin brands, but is made by Toshiba and has a 7-year warranty. The system has been working fantastically for about a month now, getting us through some very warm days and a full-on 90+ degree heat spell. The air handler is completely silent, and the condenser runs quietly and without any noticeable vibration at all. We've tried the heating and it appears to work as well as the A/C; we'll find out for sure soon enough. This unit was probably a little oversized for what we needed, but I wanted to make sure there was enough power to reach into the poorly-insulated cattery side. With the room-to-room fan setup so far there's only about a 3-5 degree difference, if that. This Senville system has made a world of difference in comfort, convenience and (hopefully) energy savings for us. Now all I have to do is convince my better half to install one or two in our house! UPDATE 9/19/17: We've had to use the heater since it seems Fall has officially arrived and it works just as well as the A/C. There are no hot spots or hot air blowing - just a warm, ambient temperature. We'll see how things go this winter, but so far we haven't had to change the unit out of Auto Mode at all. UPDATE 2/18/20: Our unit continues to to work perfectly! I make sure to vacuum the filter every couple of months due to the dusty, furry conditions in the studio. It is generally set at auto 75 degrees. I have to adjust up or down a little if its cold (in the 30s) or warm (in the 80s or above) in order to keep the poorly insulated adjoining cattery comfortable. If it was just the studio alone I could literally set it and forget it. UPDATE 11/29/2024: This Senville has been working nonstop except during power outages for over 7 years! It has not malfunctioned even once, and continues to provide spot-on temperature regulation. I leave it on Auto and still tweak the temperature up or down, depending on how much moisture is in the air, which seems to affect the feels-like temperature. The only negative I can see is that the insulation around the lineset outside is breaking down. I will probably need to have someone come out and replace it. Lastly, the only other downside was my husband passing away before we could get another unit installed in the house. The takeaway? Don't wait to get it. You'll love it. But also have a backup plan if the power goes out. ... show more

Price is right, look is good. A quiet and effective energy-efficient AC.
Size: 18000 BTU
=== General information === Everything arrived on time, well-packaged and functional and the Senville 18HF is keeping us nice and pleasantly cool in central Oregon during the 2015 late-July heatwave, whereas the house was nearly like a sauna at the peak during 95+ degree previous heatwave. The Senville mini-split heat pump (and mini-splits in general) are *much* quieter than window AC units or "portable" indoor AC units. I can actually hear the TV and conversations easily with the Senville 18HF running, but couldn't hear the TV so well when we temporarily tried using a portable AC unit from a big box store, prior to getting the Senville. The portable unit cools well. It's just ugly, consumes too much floor space and is loud. You may wonder why mini-splits are substantially quieter than other indoor units. The reason is, mini-splits have a split arrangement, where the compressor unit (e.g. the workhorse) is outside, away from people on the other side of a wall, where there is also enough room to facilitate its larger fan. The fan, being larger than is feasible for a window AC or portable indoor AC unit, can move the same amount of air, while spinning more slowly and quietly. Also, mini-split indoor units use magnetic bearings (where the axle floats in a magnetic field instead rolling on steel ballbearings). That keeps them whisper quiet. The Senville 18HF is modern looking with a nice readout display on the indoor unit. It's got a high enough energy efficiency rating (HSPF value) to qualify for Oregon Dept. of Energy rebate (as of 2015). The Sena-18HF unit is HSPF 9.5 (and SEER 22). Note that, while HSPF 9.5 is not the very highest energy efficiency unit available, it is still energy efficient enough to make the grade by the DOE (whereas many don't). There are less efficient units available cheaper, and you can also buy mini-splits with higher efficiency, but they tend to cost more. You have to find the sweet spot for your budget and sensibilities. The seller, SoGoodToBuy.com (and Senville.com) always answered phone and provided good support over a number of calls for various reasons ranging from specs, to warranty questions, questions about mounting, line sets, etc... === The following section is primarily applicable to DIYers === To save money, I did this as a *partial* DIY install. It all starts with having the installation specs, as there are many critical numbers, such as voltage, amperage requirements, indoor and outdoor unit sizing, placement, spacing, refrigerant lines, etc... I did a lot of research and homework. Specifically, I poured my own concrete pad (easy - just four 2x4s for a frame, screwed it together, leveled it, used Senville install notes to distance it properly on all sides, stakes to keep it in place, and about 4 bags of quickcrete concrete from home improvement store, mixed in a wheelbarrow with a shovel, trowel to smooth the top, covered with trashbag plastic and sealed it as well as possible, and waited 5 days for full cure). Mounted outdoor unit to it using a an inexpensive wall-powered $45 hammer drill from a box store and concrete anchors (e.g. the screws with the collars). I installed the "line hides" that cover the tubes and wires on the outside wall and look better (note: bought those separately online via another Amazon seller). I routed the refrigerant lines along the outside wall, between the indoor and outdoor unit, bending them very very carefully to avoid kinks, leaving about 1' extra at the indoor unit end and 1' extra at the outdoor unit end so the HVAC guy could cut, flare and attach. I also installed the indoor unit, entailing putting up mounting bracket level, properly distanced from ceiling, floor and other walls, with toggle screws, and drilled 2.5" hole in wall (measure 20 times, cut once), attached the indoor unit to the bracket, and pushed the lines through and hooked up the wire between the indoor unit and outdoor unit (Note: "Ask This Old House" has a video on mini-split installation and various things about doing this kind of thing on youtube). Though I did the DIY to save money on a tight budget, I was very careful about the critical aspects of the install. To be sure to not void warranty, harm the unit, and so that I could qualify for DOE incentive program. I shopped around and got a good price from an electrician to install the 240V outdoor "disconnect" outlet. I also found an HVAC company that supported my DIY approach, contracting to specifically connect the refrigeration lines and do the critical nitrogen flush, leak test, and line vacuum. Note refrigeration line stuff needs to be done right and requires special tools and some experience. I could have probably managed but would have had to pay for tools, and one learning mistake and I'd have blown it. Plus, no rebate. The HVAC people did the unit start-up and signed-off on the installation. It is more stressful to do the DIY thing and took substantially more time and research to understand what it's all about and what I needed to do, and find install parts and specifications, it did save me money. The DOE rebate will more than cover the cost of the HVAC guy and electrician, and worked out well. YMMV ... show more

Great product for the DIYer with special notes
Size: 18000 BTU
This is a perfect model for 850-1000 sq feet. The head unit and heat pump unit are very quiet and energy efficient. For the DIYer, the instructions need to be re-done, alot of details are missing. If you are going to tackle this on your own, here are a few good tips and know hows. First the instructions..the pictures are tiny and do not reflect the detail needed when doing a few of the critical steps (like electrical connections) I watched 3-4 videos of other installations of mini-splits and took good notes. Just read through the instructions first and watch a few videos. Second...performing the vacuum on the line is a critical step, knowing the tools required and the connectors is anohter very important aspect that should be in the instructions. I purchased a vacuum (not cleaner) to perform the vacuum procedure, but forgot the brass connector require to connect heat pump to vacuum! took three days to get one! Overall, I had the skills to do this myself and I installed in an afternoon. I also tackled the wiring, which required a 20amp double pole breaker, routing the 12 gauge wire in conduit to a AC cutoff box, also to the outside of house, then wire from AC box to Heat Pump and then wire the connection from head unit to Heat pump. Connecting the lines and the brass fittings; make sure you purchase the Nylog Gasket sealant, be careful with the brass piping, bend slow and easy to get the route needed from head unit to heat pump. After performing the vacuum test and leak test, I put both electrical switches on (AC Cut-off and 20amp double pole in breaker box) Turned the unit on and had instant AC and then switched over to heat! The remote is easy to use and had the option to control via Alexa or Senville app via smart phone, I connected to smart phone and boom! Full control and finally awesome heat for a little house. Also the SEER rating was really good and the unit is Energy Star, so plus plus. Overalll super happy and can be done by anyone with basic wiring, plumbing and handy person skills. Took me 4.5 hours in total. Going to purchase a few more for another project. ... show more

Excellent Mini Split and Outstanding Customer Support
Size: 18000 BTU
I’m extremely happy with my Senville Aura mini split. The unit is quiet, powerful, efficient, and clearly feels much higher quality than other brands I’ve used before. One important thing for buyers to know: the USB adapter included with the unit is only for Alexa integration. I originally thought it would fully work with the Senville app, but the Alexa version has limited controls. The full Senville app USB adapter supports many extra features like Humidity Control, Turbo Mode, and the Eye Function. What really impressed me was Senville’s customer service. I contacted support and Tom from Senville Support responded quickly, explained everything clearly, and even helped me with the USB key situation after I provided my Amazon order information. The support experience was excellent from start to finish. I previously owned a Della unit and had a terrible experience with both quality and support. Senville has been a completely different experience — much better product quality and truly professional customer service. Highly recommended! ... show more

Shoulder Season Heating Alternative
Size: 18000 BTU
Let me preface this by saying the unit has only been running for a few days. This is not the project for the average DIYer, but if you know how to flare and bend copper lines, have a vacuum pump and gauges, and how to run electrical wires you might be able to install this mini split. Installation was straight forward by the instructions but the wire colors and diagrams don't match. It's easy enough to correlate/verify the wire colors from inside to outside units. I had an HVAC tech friend oversee the installation and vacuuming of the unit and everything went very well. The instructions only called for a 20 minute vacuum down after a 5 min initial leak down test, I let it go 60 mins to be sure. After vacuuming, the refrigerant was released and I was advised to let the unit sit for an hour before starting, just to be sure the liquid was dispersed equally. Was it necessary? I don't know but it's what was recommended to me so I did it. I've only used it for heat so far but it works amazingly well. I'm getting older and the appeal of firewood has passed. I still use firewood but hopefully I can transition to less labor intensive means for heating that won't break the bank. In 30 degree weather I'm spending about $1.25 per day for heat in my 800 square ft well insulated house. I'm super happy about that. This mini split is the answer to the shoulder seasons where it's not cold enough for wood fires but heat is still needed. An important note about the remote is that it has to be pointed at the indoor unit or the temp will will default to the minimum 62 deg temp. Which is actually kind of a good thing because if the remote loses signal, or the batteries go dead, you'll still have heat. The downside is the lowest temp is 62 degrees. I know several people who'd like to get one of these units but don't like the fact that it can't be set to a lower temp of around 40-45 degrees when they go away for extended periods. Also, the WIFI kit was included so there was no need to purchase it separately. I haven't used it yet but it was awesome that it was included and I didn't have to spend any more money on it. One last thing, the outdoor unit does vibrate enough that it can be heard inside the house if it's hung on the wall. It's not enough to bother me but it can be heard, and if that's a problem then locating the outdoor unit away from living areas should be considered. ... show more

Would give between 4 and 5 starts if it was an option.
Size: 18000 BTU
We got this split unit this year instead of making costly repairs to our old steam heating system in our 120 year old ranch style farmhouse. We have not tried the cooling yet, but our house stays pretty cool in the summer and we barely ever use AC...so I'm sure it will work just fine. We mostly bought it for heating, and it has been almost exactly as we expected. It is installed in our main living space which is about 750sq ft not including a small hallway and four additional rooms that we keep the doors closed. We got the 18k btu aura model. During cold weather, it heats great. During temps below freezing, it keeps up but struggles some. We have had some single digit temps and we have to run it at full steam...but it does keep it warm enough. We like it relatively warm compared to most though. We even had a blizzard this winter with over a foot of snow and it miraculously kept working away. It did freeze up to a huge block of ice at one point and I had to melt it with warm water because I was afraid of damage to the unit, but it kept working the entire time. I also shoveled the snow from around the unit and it. It is installed on a Senville standing mounting bracket something like a foot or so above grade. The only reason for 4 stars instead of 5 is because of the stated square footage it covers. We are on the low end of the suggested coverage but feels more like we are over. I would have to concede that our home is not superbly insulated and is quite old though, so anyone with a newer home will likely have better results. Also, the layout of our home required us to put the indoor unit in a less than ideal location in the corner of the room, likely exacerbating that particular issue. All in all, I would DEFINITELY recommend this unit. I've only had it for a couple of months now...but compared to heating fuel oil that we would have used during that time...it seems it will pay for itself within a single heating season of use...maybe two. Hopefully it lasts a very long time. ... show more

Don't hesitate! Read my 1 year evaluation of this
Size: 18000 BTU
I waited a full year to review this....I'll try to keep it short. If you have DIY experience or are handy, DO it! You won't be disappointed. I added the 18k version to my spray foamed addition and couldn't be happier. I can monitor it and adjust through my alexa and phone from anywhere anytime. (I use it in the off seasons for heat before I turn my boiler on, I can set it up to come on before I get home and everything is nice and cozy. ) prior to this, I had window air conditiong and don't cool my house continually. I live in the middle of a field so the breeze is nice. But about 12 days a year the humidty is awful. this is the perfect solution for me. Install was not that hard, just be patient and thorough. I waited over a full year to review for a reason, I figured this was a cheap knockoff and might just not live long... I research the crap out of things. I believe this is a Midea unit and comes with a great warranty (especially if you have it installed by and HVAC professional) I did not, I'm a mechanic with limited A/C experience and was able to get this done and working well. It is also super quiet and I can only really hear the moving air. Defintely no compressor noises (wall mount on concrete foundation) I have also installed two other units now for family members, All are working great. We even installed one in my sisters barn feed room, Just because it was cheap and she wanted some relief in at least that room of the barn if needed. She loves it!! (12k btu) ... show more

Wish there was zero stars…….NOT HAPPY!!!!!!!!
Size: 18000 BTU
I bought this product thinking it would be so much easier to deal with than a big unit. I looked for a few months and watched videos on this type of heating and air combination. I looked forward to putting it on my little 560 sq. ft cabin. I bought it mid September and didn’t get it installed until the end of October. Got a tech to come check it all over and start running the unit. The PSI while heating won’t go above 119 so while the tech was here I call the Senville Company. The Senville Company tech decided after asking a bunch of questions of me and my tech that we needed a new control panel. So, a week later my tech comes back out to install the control panel. Still nothing!! I have talked to three different Senville employees, followed all of the instructions they gave me, answered every question, sent pictures, and had my tech talk to them only to be told they won’t help me. The weather is getting colder and colder. Aside from the money I have had to pay my local HVACH Tech I am having to spend money on an alternate heating source for my cabin, on top of what I spent on the unit in the first place!!!!! DO NOT BUY SENVILLE PRODUCTS PERIOD!!!!!!!!! Update: I finally heard from Senville and they decided after more questions, pictures, videos, and yalking to my installer (who has been installing HVAclC units for some 30 plus years) they sent us a totally new outside unit. I had my experienced tech install the unit. Within a week we started having issues again. The unit keeps going into df (defrost mode). I have called, messaged, emailed, and sent video to Senville for a couple weeks now. Finally they call and tell me it's my installation that is messing up! So, I called around and had four different techs all of whom have experi3nce installing this type of unit and all have over 20 years of experience. Everyone of them said it is another faulty unit!!!! I even let one of them take the first messed up unit to his workshop to disassemble and figure out what is wrong. He said if I paid to have it fixed I would spend the $1500 again.
