A word of warning, though: Get someone to install them that is used to installing minisplits.

We didn't know the AC company we chose didn't normally do them. They told us about it, sold us on it, and then royally screwed up the installation. We had them fix it a few times, then they had to basically replace all the inside heads. And even after that, they still aren't right. Some of it is simple incompetence, but some of it had to do with knowing how to install a minisplit in particular.

We're now paying another company to completely replace it, just 2-3 years later. The manufacturer's warranty is gone (Don't buy Lennox! 2 year warranty and garbage hardware!) and the free (warranty) labor from the AC company isn't worth the time and hassle.

I researched the heck out of this before getting one for a rental. Mitsubishi is the way to go if money is no object and you want the most reliable/lowest hassle system.

If you want to save a little money, Daikin is almost as good and a little cheaper. Below that you’re rolling the dice on service calls.

Glad to hear you say that. We're getting Mitsubishi this time. It's actually going to replace our downstairs AC and the minisplit.

Plus, the mini-split recessed in-ceiling cassettes from Mitsubishi are wondrous. No goofy unit hanging on the wall.

We went the Mitsubishi units (I see these and Fuji everywhere) and a certified installer. They add two years to the warranty if you have one of their certified installers do the work. I have high confidence in Mitsubishi being around to honor the warranty.

Same here - Mitsubishi Diamond installer for mini splits that do heat and A/C. Almost two years in and still working perfectly. I believe I have a ten year warranty against most issues.

We're getting Mitsubishi this time, so I'm glad to hear that.

I installed my own import brand dual minisplit vacuum pump and all. Sounds like you just got a terrible HVAC co the first go round.

I recently installed two MrCool DIY minisplits which worked out great. They come with pre-charged quick connect coolant lines so you can install them without the need for flushing coolant or soldering the lines.

If you're comfortable putting a hole in your house for the line and running power, it can really save a lot of money.
