Efficiency. It’s a word homeowners live by when they’re
looking for new appliances and upgrades. Mechanical devices today are built
with energy efficiency in mind, and there are government programs such as
ENERGY STAR that help consumers spot top products in energy savings.

Because an air conditioning system in Boca Raton, FL consumes an enormous amount of electricity around the year, a high-efficiency AC can be a major money-saver. If you are currently on the market for a new air conditioning system to replace your old one, efficiency is probably one of your most important criteria. But how can you know the efficiency of an air conditioner and whether it’s worth installing?

The Basics of SEER and EER—Air Conditioner Efficiency Ratings

You need to look at two ratings on an air conditioner to
understand its efficiency: SEER (seasonal energy efficiency rating) and
EER (energy efficiency rating). As the names indicate, they’re similar
to each other, and are usually listed side by side with a slash between them.

EER is the ratio of the amount of cooling an AC puts out (as
measured in BTUs of heat removed from the air) to the amount of electrical
power used (as measured in watt-hours). To determine this ratio, a single test
is performed under set temperature and humidity conditions. The higher the EER
number, the more efficient the system is at turning electrical power into
cooling.

SEER is the same ratio of cooling to electrical power. The difference
is how the test is conducted. SEER is determined over multiple tests of varying
temperature and humidity. This finds the system’s average performance over a
season rather than under a single set of conditions. The SEER number is always
higher than the EER number.

What’s a Good Number of SEER/EER?

What’s good for a home depends. We can give you the
requirements of the ENERGY STAR program for a unit to receive certification: a
central split system air conditioner must have SEER of at least 15 and EER of
at least 12. Making the change from an old 10 SEER system to even the lowest ENERGY
STAR unit can mean 35% savings over the summer alone.

You can purchase an air conditioner with much higher
SEER/EER than this, however. The newest types of high-efficiency air
conditioners with scroll compressors, variable refrigerant flow technology, and
multi-stage compressors can have SEER and EER in the 20s. These units cost more
than mid-efficiency systems such as 15 SEER air conditioners, so you’ll want to
weigh a number of factors when you make your choice.

This is where you’ll love having our experts on the job. We know all about finding the right air conditioner to match a home and a home budget. We’ll not only ensure you choose a new AC that meets your needs, we’ll size it correctly so that it won’t end up wasting power and canceling out that high SEER/EER. (This happens all too often with inexperienced and amateur technicians.) All of our techs are NATE-certified and factory-trained to see you receive only the best.
