Symptom

 

:

 

Indoor

 

unit

 

blows

 

smelly

 

air.

 

Reason

  

:

 

Dirty

 

filters

 

and/or

 

evaporator

 

coil.

 

Solution

 

:

 

Clean

 

the

 

filters.

 

If

 

the

 

coil

 

is

 

dirty

 

have

 

the

 

evaporator

 

professionally

 

cleaned.

 

Run

 

the

swings

 

in

 

the

 

room.

 

Reason

  

:

 

Indoor

 

unit

 

installed

sensor

 

deficiency.

 

Solution

 

:

 

Higher

 

locations

 

in

 

the

 

room

 

will

 

have

 

warmer

 

temperatures

 

and

 

the

 

system

 

will

 

measure

 

the

 

temperature

 

at

 

the

 

height

 

the

 

indoor

 

unit

 

is

 

installed.

 

User

 

can

 

compensate

 

for

 

this

 

by

 

setting

 

the

 

temperature

 

settings

 

slightly

 

lower

 

or

 

higher

 

than

 

actually

 

desired.

 

Clean

 

the

 

filters

 

weekly
