- Auto Restart & Anti-Mildew Function: In the event of a power outage, the system auto-resumes with previous settings. The air handler also includes an anti-mildew mode to eliminate excess moisture and keep your system clean and fresh.

Let customers speak for us
I already have one that’s 15 years old at least and it’s still working fine.
The unit has been unboxed and looks good but we have not had it installed yet. I will be happy to provide a review once we have it installed and can test it out. I can say that your service was excellent and your updates were always appreciated. You made me frrl like a valuable customer. Thank you.
The Stand was received for the mini-split in an acceptable time limit. Our unit being the largest of the mini-splits was a concern. The footprint of the unit maxed the stands limits. it took some time to get it to fit, but it finally worked. it didn't come with bolts to secure the mini-split to the stand. they have to be purchased separately. The stand seems to be of good quality, and we'll see how it stands up to the weather as time goes on.
It would be nice to have the slots to secure the unit to the stand a little longer, but it works.
Senville 28000 BTU Ceiling Cassette Air Conditioner - Heat Pump - SENA/30HF/DIC
Is not completely install yet . Appears to be of good quality . Shipping was fairly fast.
I have an old house where it is impossible to install venting, etc. for the regular heat and air conditioning. I have mini splits and they work great for any area. I have 2 Senville mini splits and I love them. Quiet, efficient and get the job done.
Is a small propane heater. It works pretty good for a small cabin , RV etc. Dont need electricity. Just a small propane tank. Dont consume alot . A small tank will last about 3 day if you run it at full capacity though the night. No propane small, no carbon monoxide. It has a vent for the out side. But this 8 thousand btu is not for a whole house heat.
Purchased a Senville 24k Concealed duct that was on back order but they kept me informed throughout process. Shipped immediately once back in stock, its now installed and could not be happier.
Ordered an item that was on back order. Took a long time to get but Tiny houses communicated the best they could through out the process. Have not installed you but impressed with what I’ve received.
It’s so far been a great system. Works like it’s supposed to.
Excellent product. Delivered with no problems.
They are awesome. Very quiet
The purchase of the A/C system from TinyHouseEssentials was a smooth process with amazing communication from the time of purchase straight to after delivery... great transaction, great company.. will most definitely do business again.
Sorry it won't be installed for another month. Area under construction now.
This compost toilet is the best. I even took off all the extras because it's really not needed. I plugged the pee bottle off. I'm not emptying urine. Love it so much I ordered 2 more for my home.
