Frigidaire Home Comfort Products
Frigidaire offers consumers a complete line of room air conditioners, dehumidifiers, portable air conditioners and ductless mini-split air conditioners desgined with the latest in technology to meet every need. The products provide consumers with fresh designs and features that work with any decor and meet the highest of expectations in both functionality and quality.

For 2011, Frigidaire has made further improvements to the product offering driven by consumer needs and requests. The heat and cool offering of window air conditioners has expanded with the addition of a heat pump model providing better heating with up to 70% more efficiency. In dehumidifiers, they have increased capacity of the smallest model by 20% and improved the hose connection to the exterior of the unit for better accessibility. The bucket design has also been improved to ease in handling and prevent spills. The portables line now includes true 5,000 BTU and 7,000 BTU models for a full offering. And this year, Frigidaire has rounded out the cooling portfolio with a complete lineup of ductless mini-splits.

From small bedrooms and bonus rooms to large, semi-commercial areas, Frigidaire is committed to providing quiet, efficient, and reliable air conditioning products for years of trouble free comfort. Available at AJ Madison.

How to Choose a Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is significantly lower than the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.

Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs.

Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an oversized unit will cost more to buy and operate and it will not dehumidify properly.

We can help you to calculate capacity. Be prepared to provide specific information on:
  • Room Dimensions
  • A simple floor plan to show the location of doors and north-facing windows
  • The number of people it will serve
  • Sources of heat such as lamps, TV and appliances
  • An explanation of what's above the intended room
  • Your insulation provisions

Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures - step up to the next BTU size.

Product Reviews
Rated 3.5 out of 5 by 38 reviewers.
Rated 4 out of 5 by Ideal for crawlspace Love the fan that turns on when in operation. Ideal for circulating the air in my vent sealed crawlspace. The fan will cut off once your RH setting has been achieved or you can select the CL option and have the fan run continuously. Good value at less than $200. Also, much quieter and less expensive than my previous LG 45-pint purchased about 5 years ago. 5/22/11
Rated 5 out of 5 by Great Appliance I have just plugged in this 50 pt unit (had to return 25pt) which is really in excess of my square footage and use requirements. It is inobtrusive, very quiet even on high and has reduced the desired humity level in an hour. The smaller one ran continuosly for 5 days and never reached my desired humidy level. My room, including closets, 2 small adjacent rooms and a bathroom, is under 500 sq ft. The built in humidistat is relatively acurate +/- 2 or 3 % based on my separate humidistat. Worth the little extra money and also runs quieter than 25 pt. I have and have had over many years other Frigidaire appliances . When I do all the comparrisons with other brands Frigidaire is always #1 and never have I had any problems or needed service going back 10 years. 6/18/11
