If you have some electrical know-
how but need extra guidance, don’t
forget your local electrical inspector.
It’s not an inspector’s job to act as a
consultant, but most will give you
some advice and outline code require-
ments. Expert help and certainty that
the job is done right—not bad for the
cost of an electrical permit.
The condenser needs a level surface
to rest on. You could pour a concrete
pad, but a plastic condenser pad
($50 and up online) is instant and easy.
We mounted ours on condenser wall
brackets ($60 online).
The fabric sleeve covering the line
set isn’t attractive or easy to keep clean.
The solution is a plastic line set cover
kit, which costs about $50 online.
HOW IT WORKS
A mini-split system has two main
components: an indoor EVAPORATOR,
which cools the air, and an outdoor
CONDENSER, which dissipates heat.
They’re connected by a LINE SET,
tubing that passes through a baseball-
size hole in the wall, carrying hot
refrigerant outside and cold refrigerant
in. Our line set also included cable to
power the evaporator and a drain line
to carry condensation outside.
