If the cooling system in your home has started to fail, then it may be time to start looking into a new system. There is a lot of variation out there when it comes to HVAC systems, and you will need to look at all of the different bells and whistles when you make your choice. While this is true, you should make sure that you do not overlook some of the features that help to encourage energy efficiency. Keep reading to learn about a few options.
Large Scale Evaporator Coils
Your AC unit will have two different sets of coils, called evaporator and condenser coils. The evaporator coils are the ones that sit within the indoor unit and are responsible for the majority of the heat exchange. Basically, they pull the warmth from the air, and the coils come in a variety of different shapes and sizes.
Bigger coils that are shaped in a certain way will encourage greater heat exchange through the surface area of the coils themselves. And, this will allow for the greatest energy efficiency. So, make sure that your evaporator coils are large and feature either a pyramid or an N-shape.
The coils themselves should be easy to reach through the front panel of the unit so you are able to clean them properly. This is wise for energy efficiency as well.
Along with the bigger coil, make sure the unit has a fan delay. The delay keeps the fan moving for several minutes after the unit turns off, and this helps to move all of the residual cool air into the ducts.
You probably know that a new filter is required every few months to make sure dirt and debris are removed from the air before it is forced over the evaporator coil. If you forget to replace the filter, then air may not move through the system properly and this can interfere with the energy efficiency.
Some AC units come equipped with sensors that detect when the filter is dirty and in need of a replacement. Usually, a light will shine when the filter needs to be replaced, so look for this feature.
Of course, you want to make sure that you have the correct filter for the unit you own so that air can move smoothly through the device. Some units will have two filters as well, and you may want to look into this. Both filters have larger openings to allow for the best airflow while also collecting debris appropriately.
