Four Ways To Make Your AC More Energy Efficient

Air conditioners can be a big monthly expense during the hot summer months, but there are a few things you can do to improve your system's energy efficiency. Not only can this help save money, but it can also help to ensure your air conditioner runs smoothly when you need it most. Talk to your HVAC contractor and consider the following suggestions for improving your system's energy efficiency.

Change Your Filters

Clogged air filters can cause your air conditioner to run less efficiently, and they can also help circulate dust and allergens throughout your home. The U.S. Department of Energy estimates that changing your filters can reduce your AC's energy consumption by 5 to 15 percent.

Clean Your Registers

Just as with air filters, clogged or blocked registers can make your air conditioning system work harder to keep your home cool. If you have pets in the home, the registers become clogged with fur as well as dust and dirt. Make cleaning the registers with a hose attachment part of your regular vacuuming schedule. You can remove the register grates for this task, or you can simply use a longer, narrow attachment to clean in between the grate bars. 

Replace Your Air Conditioner

If you live in an older home, or if you've never replaced your air conditioner before, it may be time to invest in a new unit. Energy Star-rated air conditioners can use up 8 percent less energy than new air conditioners that are not Energy Star-rated. For the best results, it is recommended that you replace your heater and your air conditioner at the same time, as you won't get the same level of efficiency if the AC is connected to an older heating system.

Install A Programmable Thermostat

Programmable thermostats make it easy to adjust your home's temperature, but they also provide a host of other benefits. Thermostats with built-in sensors can regulate the temperature in your home independently to maximize energy efficiency, and they can be programmed to turn the air conditioning down as the temperatures outside drop. Some thermostats can even be controlled via your smartphone or tablet, so you can turn the AC up or the heat down while you are away from home.

Discuss your current energy usage with an HVAC contractor, such as those found at, and have him or her perform an inspection to identify other ways you can make your system more energy efficient.
