Can this be a DIY job, or would you recommend this only be done by a professional?

We had it installed a couple of years ago, I'm comfortable doing most home improvements but the installation of the Split Ducts was something I left to the professionals

You can search my past post and see the installations.

you're dealing with compressed, regulated, expensive gas that you can't see (if it leaks). forced air HVAC work is bit more do-able for the DIYer, but like jeff -- even with a few well-earned battle scars -- i'd not attempt it. plus, you'd void any warranty on expensive equipment. i had a neighbor self-install and call out the pros to test and fill, but he's a pretty advanced practitioner and it was only a one-head, above-ground (i.e.: tubes not buried in a foam roof) installation. i can think of smarter ways to save money. additionally, i find a ground installed mini-split system (especially if it's just 1 or 2 heads) with exposed supply/return lines (wrapped in foam) more visually (and physically) obtrusive than a "window unit" plumbed neatly through the wall (we have both (minisplit and wall-units) as it didn't make sense to spend $8-12K for a 2nd minisplit for the side of the house when 2 well-positioned/plumbed window/wall units at $300 each work fine (our 1st minisplit system is roof installed with lines running under the foam roof) -- not to mention if one breaks, it's a fairly easy pul out and replace (i fear when something happens to our minisplit insofar as repair costs). plus, most minisplits -- if done "right" -- require (1) a permit and (2) a dedicated 30-40A line.

How do I fix the air conditioning in my house? The air conditioning in our house went out over night & last time it happened (about a month ago) we changed the filter & it worked again just fine. So, we changed the air filter agian, but this time no luck.

Have you considered calling a professional?

Mitsubishi is a company known all over the world for taking its customers needs to heart and they have truly outdone themselves with this new type of installed air conditioner. The Mitsubishi ductless air conditioners are a great way to keep cool all summer long. They'll even help you heat your home in the winter for a fraction of the cost that your existing base board heaters will cost you.
