Air Conditioner Power Consumption Facts

air conditioner power consumptionDid you know that when it comes to air conditioner power consumption, approximately one sixth of the United States’ total electricity that gets produced goes to air conditioning buildings? It was because of that fact that in January of 2006, the U.S. Department of Energy raised the minimum energy efficiency rating for air conditioners.


The new increased energy efficiency ratings are useful for everyone since they help with air pollution as well as reduce business and home energy costs.

What is the Efficiency Level of Your Air Conditioner Power Consumption?

Having said that, do you know how efficient your ac unit is?

One way you can easily find it out is through learning your cooling unit’s seasonal energy efficiency ratio, (SEER), measurement.  The SEER is a measurement used for setting a basic standard to machines that are friendly to the environment. It rates an air conditioner on the basis of the amount of energy it can effectively use. If the SEER number given to the air conditioner is high, then it goes then that corresponds with the energy efficiency rating of the unit.

Since the concerns about the environment have increased, the amount of the SEER on cooling units has also gone up. For example, in 1992 the minimum SEER standard was 10.  The new law passed in January 2006 has helped increase an air conditioners efficiency by increasing the minimum SEER to 13.

The rise in the SEER from 10 to 13 indicates that the efficiency of a particular air conditioner has improved approximately 30 percent more.  However, the downside to having an ac unit designated with a higher SEER would mean that its price and the installation costs would also go up. But this does not really seem to affect most homeowners or business people.  The presumption is that a higher initial investment would ultimately be cost effective by in the long run, and they would be able to save on their energy costs this way.

If the first fact, that one sixth of the United States’ electricity goes in air conditioning, impresses you or causes you to take notice, you would be all the more pleased to know this tidbit of information.  The Department of Energy assumes that by the year 2030, the energy and SEER laws will be revised once again. The estimated savings of these efficiency rating changes are that they would actually provide enough electricity for 26 million homes for an entire year!

What Can You Do About Your Air Conditioning Energy Usage to Save Money on Home Energy Costs?

So the best way you can save energy is to bring home a good quality air conditioner. From there, after proper installation is complete, then the most vital thing is to regularly maintain the cooling unit of your machine.

You can ensure a maximum efficiency of your conditioner if you change the filters and verify the functioning of the machine from time to time.  Checking your cooling unit at least two times a year to ensure it is in good working condition is a start.  Attending to any HVAC repair needs as soon as possible will also help to maximize the efficiency of your air conditioner power consumption.



When I was a new home owner, admittedly I use to take the operation of the hvac unit for granted.  My only thoughts were to turn on the air conditioning in the summer when I got hot.  And turn up the heat in the winter when I got cold.

how your hvac system worksWhen either of those functions stopped working, my only recourse was to call for professional help.  I quickly learned that with the summer heat here in Phoenix, that gets to be a costly service when that help is needed on a consistent basis.

Through these service calls, I discovered that doing some basic maintenance and minor repairs on my own has helped save me quite a bit of money.  It’s also what I would recommend to help you cut down your service cost.  But before taking on that do-it-yourself type of task, it’s helpful to know how a hvac system works.  To learn that, here are the hvac, heating and cooling system basics.

How your HVAC Systems works 101

Every system used to control the climate in your home has three basic components.  They are: a warm or cooled air source, a way to distribute the air that’s been heated or cooled to each room in your home, and a way to control or regulate the system which typically is the thermostat.  When put together, the warm air source, such as your furnace, and cool air source, such as the air conditioner, typically uses the same air ducts to distribute the air and thermostat to regulate the temperature.  Any of these components of your hvac system could be the culprit if it stops working.

A common principle is put into play when it comes to the heating and air conditioning on your system.  That principle is that heat always moves from a warm object to a cooler one, much like the manner in which flowing water travels from a higher level to lower level.  In short, heat is put into the air by the furnace in order to warm your home and heat is removed from the air by your air conditioner so as to cool your home.  Simple right?

Some form of fuel is burned by all hvac units be it electricity for the air conditioner or gas or fuel oil for the heater though sometimes even the heater will use electricity.  If a heat pump is used, it is powered by electricity and will both heat and cool air.  It will pull the heat from the air inside your home during the summer, and it pulls the heat from the outside air to warm the home during the winter.

So when you turn your furnace on, fuel is consumed to power that source.  Whether it’s electricity, gas, or oil, it’s the burning of that fuel that produces the heat driving it to the living areas of your home via wires, pipes, or air ducts.  Then that heat is blown out through heating panels, radiators, or registers.

Electrical power is used to cool a gas in its liquid state when an air conditioner is turned on.  By making contact with the cooling coil, the warm air within your home is cooled and that air is distributed via ducts and registers to each room.
