Friedrich PDE09R3SG

New Design For Higher Energy Efficiency
The advanced coil design of the SG Series maximizes the internal surface area to deliver higher efficiencies providing EERs of up to 13.0.

Dependable Performance You Can Count On
It begins with the highest quality materials and components such as stainless steel endplates on the coils and galvanized, zinc-coated steel wall sleeves brought together with durable construction and rigorous testing. Friedrich PTACs are built to deliver years of reliable performance.

Engineered For Maximum Guest Comfort
Quiet, yet powerful airflow quickly reaches all corners of the room. The two motor design and thick insulation on the inner walls reduce the indoor sound levels.

Guests can select the Constant Fan mode, which produces a steady stream of white noise in both c ooling and heating modes that masks sound level changes when the compressor cycles on and off, and also masks outdoor noise.

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.
