I have a 22x22 workshop that is stand alone with 12 foot ceilings. It
has a concrete pad with some insulation in the walls and roof. My
existing AC windows unit just died and I have been looking at the dual
AC/HEATER units as a replacement now. In the past I have used a
propane canon type heater to heat it in the winter. Amazon has a
Frigidaire FAM18ER2A unit which is a little large in the cooling BTU
rating for my shop. I also have been using a stand alone dehumidifier
to keep the humidity down. The old unit was a 12000 btu and it did a
fair job most days.
The new one runs on 220 which is not a problem and I hoped it would be
a little cheaper than the older 110/15 amp unit.
Does anyone have any experence with these dual units.

Product Features

* 18,500-BTU air conditioner with 16,000-BTU heat and electronic
controls
* For rooms up to 1170 square feet; 10.7 EER; full-function remote
* Variable-speed fan; multiple air direction; 24-hour on/off timer
* Energy-saver and sleep modes; quick-mount window kit; tilt-out
filter
* Measures 25-3/8 by 23-5/8 by 17-3/4 inches; 1-year full warranty

Shipping is free so that's not a big problem.

Something to consider. The unit appears to be more than adequate and that
might be a problem It is normally recommended to not buy too big of a unit
as they will cool every thing down quickly and then shut down. This can
cause excessive condensation to accumulate because the unit does not run
long enough to actually dehumidify the room also.

Is this a heat pump, or straight electric heat? If it is straight electric
it will consume about 4700 watts per hour running on continuous heat.
Depending on your electric rates , say $0.10 KWH it will run you about $0.47
per hour to run for heating.
Also how many BTU do you need to heat your shop? My bet the propane heater
you were using has a much larger BTU output.I know where I live the heat
from that unit would never even take the chill out of the air in the colder
days of the year!

We live in western N.C. where it's not bad but does run about 20-40 in
winter. My shop only hit below 32 three times this year compared to 10
last year. I keep all my glue and water based products in a light box
which comes on around 35 degree.
I really like the propane heater as it raises the temp about 1 degree
a minute in the winter and have wondered how this dual unit would
compare. If it not going to get the job done then a smaller AC maybe
better. THis is the lowest cooling BTU I could find and do believe it
is to large I'm afraid.
The unit is a straight heater with strips
