Nashville area residents know that temperatures in the Summer months can be pretty brutal. Your home comfort depends on a properly sized and installed air conditioning unit. Precision Air is an authorized installing and servicing dealer for all major brands of heating and cooling systems, but after many years of dealing with different makes and models, we have come to realize one manufacturer stands above the rest in quality and reliability.
That name is Daikin.
Daikin has strived with strong passion to develop technologies which led us to become global No.1 in air conditioning.
While we feel Daikin is one of the best, there are a number of excellent manufacturers in the marketplace and we also sell and service other top quality products.
Different Types of Air Conditioners
There are many different efficiency levels and cooling capacities or “tonnage” of air conditioners available today, but all the different units can be divided into two distinct major types or categories; single stage and two stage or two speed air conditioners.
Efficiency or SEER
The efficiency or SEER rating of an air conditioner refers to how electricity that particular unit will consume to keep you cool in a season.
SEER is an abbreviation for “seasonal energy efficiency ratio” and it tells you how much electricity an air conditioner will consume over a typical season. The higher the SEER the less electricity a unit consumes in a season.
Starting in 2007, the minimum SEER rating became 13. Before this, the efficiency levels went all the way down to 6 SEER or less.
The actual savings every SEER number affords you varies, but on the average it is between 5 and 10 percent savings every larger number SEER selected.
Tonnage or Capacity
The ton of an air conditioner is a rating of the unit’s ability to remove heat from your home or business.
A ton of cooling is 12,000 BTU’s and residential air conditioners are made in sizes of 1.5 ton to 5 ton in half ton increments.
A BTU is a measure of heat which stands for British Thermal Unit and one BTU is equal to the amount of heat one match puts out.
In other wards, a 1.5 ton air conditioner will remove the amount of heat the 18,000 matches would emit if they were all burning at the same time.
The reason it is called a ton is that is the amount of heat (12,000BTU) it would take to melt one block of ice weighing a ton in one hour.
The job of an air conditioning contractor is determining the correct size or tonnage of a unit for you, and in this case it is not a matter of the more the better.
An oversized air conditioner will not remove the proper amount of moisture from the air to give you the comfort you deserve. An undersized air conditioner will run constantly even at moderate temperature and will not adequately condition the space.
There some special air conditioners you can oversize and still get very good dehumidification and those are two speed or two stage.
A variable speed furnace will also help in having a system that not keeps you cool, but dry also.
