Portable air conditioners are going Green with Eco-friendly R410-A refrigerant and lead free
RoHS (Restriction of Hazardous Substances) compliant components. Now you can stay cool,
reduce energy consumption and help the environment all at the same time.

Portable air conditioning units are extremely mobile and offer a practical solution to unique
cooling problems when traditional options such as window air conditioners or central air aren't
viable. Here are a few situations where a stand alone air conditioner could be just what you're
looking for.

  • New additions or that room above the garage you just remodeled.
  • College dorm rooms.
  • When window air conditioners are not permitted by the landlord.
  • The central A/C doesn't reach the uppermost rooms of your home.
  • Irregular shaped windows won't accommodate a window air conditioner.
  • Fear of damaging new vinyl replacement windows with an in-window unit.
  • Extra cooling for rooms containing sensitive electronic equipment like computers.

Other portable room air cooling units such as a fan create a cooling breeze but do nothing to
reduce humidity; while a portable swamp cooler actually adds moisture to the air as it cools.
This leaves only the portable air conditioner as a viable system for cooling and dehumidifying
when traditional cooling appliances are unavailable.

Best Rated Portable Air Conditioners
When I picked out the "Best Rated" portable air conditioners for this page I relied on the
Amazon ratings as a guide when products were available on multiple sites. Many retail
websites show only positive reviews and don't accurately reflect the complete consumer
experience.

All of the units shown here combine the highest consumer ratings with the lowest possible
price - and most include Free Shipping. Use the table below as a guide to pick out a portable
air conditioner or portable air conditioner with heater that matches your room size.

All portable air conditioning units need at least one hose to exhaust the hot air generated
by the compressor. So the primary difference between single and dual hose models is where
the intake air comes from. A single hose model intakes air from the room and recirculates it
just like a window air conditioner. While a dual hose unit intakes air from the outside
through one hose and exhausts the heated air from the compressor from the second hose.

Portable Air Conditioner Reviews for 2014
Portable air conditioners with heaters are a real convenience. However, heating capacity
varies a great deal between models based on which one of two types of heaters is used in
the unit. Some models use a separate electric heater while others use a heat pump (reverse
air conditioning).

Those that use a heat pump have the capacity to heat approximately the same area that
they cool. Those that employ a separate electric heater heat only 30% of the area yhe unit
is capable of cooling.

Portable Air Conditioner for Garage
Portable air conditioners are perfect for windowless garages because they can be vented
through a port in the door the same way you would vent the exhaust from a car.

The only piece of equipment you'll need is a 5" (ID) garage door exhaust port. (The exhaust
hose on a portable AC is almost always 5" in diameter). The exhaust ports come in a 1/4"
width for aluminum garage doors or 2" width for insulated doors and cost
around $40.

Once the port is installed you insert the hose, plug in your AC and you're good to go.

If you currently own a portable AC, and it's a single hose model, you already know this is
the exhaust hose. If you own a dual hose model, you can detach the intake hose from the
AC and it will function as a single hose unit.

Since most two car garages are around 400 sq ft, a minimum 12,000 BTU model is
recommended. You might also consider a portable air conditioner with heater for year round
use.
Which Is More Efficient, Single or Dual Hose Models?
There is much conflicting evidence regarding the efficiency question so I went straight to the
source and posed my query to a customer service rep at Whynter LLC, a well known
manufacturer of home appliances. Here is what they said:

“Operationally, a dual hose portable air conditioner has two main advantages over a single
hose unit. A dual hose portable air conditioner will (1) cool a room faster and (2) will help
minimize negative air pressure situation in the room. If the outside temperature is much
higher than the room temperature, you can block the intake hose and it will function like a
single hose unit.”

Thanks for the response, but it doesn't answer the efficiency question. However, I can tell you
this: In most cases, portable air conditioners with higher BTU outputs are more efficient than
units with lower BTU ratings simply because incrementally, it doesn't take much more power
(watts) to run a larger compressor.

And, since the majority of high output (12-14,000 BTU) units are of the dual hose design,
you could get away with saying that dual hose models are more efficient than the single hose
variety.

Cost To Run
The estimated hourly cost to run each of the portable air conditioners shown here is based on
the national average of $0.12 per kWh. The source for this figure is the U.S. Energy
Administration's Average
Retail Price of Electricity to Ultimate Customers. (.12 x watts = cost
to run per hour)
