Mini Split - wall or ground mount?
 
Planning stages of a master bedroom addition to my home. Using a mini split unit to provide for heat and a/c. What are the pro & cons of wall vs. ground mounting the outside unit?

I like the idea of wall mounting to keep it higher under the eave, away from lawn mower clippings being blown on it and trimmers doing any damage. But I am concerned of additional noise transmittal into the bedroom.

Thanks in advance!

I'd set it on the ground up on a platform out behond the drip line of the roof.
Easyer to service.
0 chance of water damage to the wall.

I build my platform big enough that I could also set my gen set on it.

I dig out all the top soil sprayed with total vegitation killer, installed steel landscape border then back filled the area with stone so I do not have to deal with grass or weeds growing under or near it.

ground mount because ease of service is a huge issue. on some of them you have to remove the entire top and cowl etc to get in an PROPERLY clean the condensor coil. not something you want to do up in the air and with a hose either.

Just one more thing I'll throw in here. Is the unit a heat pump? If so, if you get much snow in your area I'd recommend setting it above the normal snow line in your area. I know in our area we rarely have more than a foot of snow on the ground, so even a foot or two off the ground will do some good. You just want to make sure it's high enough to keep it out of the snow, but not too high to be able to work on easily.

SoCal I assume that is southern California? Doubt that snow is a problem there but you never know. Unlike the Great White North where I am and we have 150 percent more snow this yr than average. The unit needs to be above ground in cold locales so the water can drain from it and not make a huge iceberg when it defrosts in heat mode and kept away from where snow drifts may bury it.

Didn't think to check his location. :icon_redface: Yeah snow in SoCal probably isn't a big concern :thumbsup:

A foot or 2 off the ground will give it the protection you want, and still make it easy to service.

No snow here - I don't do snow. :no:

What about my concern of additional noise transmittal with a wall mount?

Mini splits are very quiet. Shouldn't have any noise problem with it being wall mounted.

Thanks everyone for the great comments! I think wall mounted a couple feet off the ground is best for my scenario.
