  • An effective and efficient DIY! Runs great!
Style: 36K Size: 5th gen
A great solution! I was able to DIY this project 100% (did have some help lifting the gear to mount to the walls). The install was involved in but manageable. Lines and power installed with ease. Outstanding heating and cooling capabilities. This was the best purchase I've made all year, a big quality of life upgrade that is already bringing down my electric bill. 10/10 would recommend and buy again. ... show more

This thing is AMAZING! We run a small business out of one of our garages. This makes it so nice when the temperatures reach 100° or 20°. It is amazingly fast, extremely quiet, and just the right size for what we needed.

  • Great company-Great Staff
Style: 36K Size: 5th gen
I have purchased two mini spilt systems from Senville, a dual 28,000 BTU unit and a massive quad 36,000 BTU unit. On the bigger unit I took on the complex task of running the lines through my attic which added significant line length but keep the lines out of view. It takes some learning to DYI these units which can be achieved by watching a view You Tube videos. I had a HVAC technician do the final vacuum testing and adding refrigerant to the quad unit. Both units worked great with a couple of exceptions that Senville took care of. The Senville customer service is fantastic and for me when making these large purchases you want the products to first work, but more importantly, if there is an issue you want the company to step-up and fix the issue. I can only speak highly of Senville and their team. Highly recommended. ... show more
