Air Conditioning SEER, SEER meaning Seasonal Energy Efficiency Ratio, refers to the measure of energy efficiency in air conditioning units. SEER ratings provide the flexibility to compare cost of various cooling system units.
The higher the SEER rating received by an air conditioning unit the more efficient it can actually perform, or in other words cooling units with higher SEER ratings produce a comparably lower energy cost than air conditioners with lower SEER ratings.
Today, most of the central Air Conditioning SEER is regulated by U.S Energy Department and by international law. Each type of air conditioning unit has its own SEER efficiency standard that manufacturers should follow in order to pass.
What is internationally called as Air Conditioning SEER is locally known as Air conditioner ratings in the U.S. Of course, one important factor that consumers heavily consider is quality, and quality in cooling units is translated in SEER star label.
Definitely everyone wants to cut down their energy bills, and with the addition of an air conditioning unit energy bills are bound to rise the following month.
If you plan to buy a new cooling system or you just want your old cooling unit replace, make sure that you are getting a new air-con unit with Energy Star label. Most likely, your older unit has a 6 or 7 SEER rating, which is way behind from today's standard.
SEER standard now starts around 10; the higher the better cost reduction can be achieved. There are many factors that affect SEER:
Installation - Installation is a factor that needs moderate attention. Some companies offer lower-end models with an emphasized installation, the only problem with these models is they don't really fit perfectly well during installation, this can definitely affect the unit's SEER
Refrigerant Charge â AC Refrigerant is responsible for carrying the heat from its evaporator coil to its condenser coil. Having too much or too little of this will affect both your evaporator and condenser coils.
Too little of this will depress your evaporator, freezing down the evaporator coil rendering your cooling unit ineffective. While too much refrigerant on the other hand will result to an increase in high pressure suction, increase head pressure, and the central air conditioning compressor will consume higher energy.
Other factors that can also affect Air Conditioning SEER are. Air Conditioning Size, Air Flow, Air Conditioner Distribution System or duct system, Air leaks from both return and supply line, and Central Air Condition Maintenance.
