Are Modern Air Conditioners More Energy Efficient?

Energy Efficiency

Cooling has become a necessity in most households. As a result, most people use air conditioners to maintain comfortable indoor conditions in hot summer months. With advanced technology, there are several new and energy-efficient AC models that make your house cooler while still maintaining lower energy consumption levels. The following guide aims at clearing all your concerns on energy-efficient AC models to help you make an informed choice. Read on to gain more insights.

1. Why Modern ACs Are More Energy Efficient

Manufacturers now develop better motors and other parts to build a unit capable of running at low capacity. Hence the new models can provide better cooling power at lower energy. If you have a unit installed before 2010, it could still be using the old R-22 refrigerant. EPA banned the use of this refrigerant due to its environmental impacts. The replacement, R-410A, is a better heat transference fluid that enables new AC units to run more efficiently.

The new models also come with variable fan speed, which lowers the AC’s operation. It enables even distribution of the conditioned air throughout the house, and since your unit won’t have to work at full capacity throughout, it saves on energy.

The multi-stage compressors in the new air conditioners are the most energy-saving features. Your AC won’t have to run on maximum compressor power each time. Based on your house cooling needs, the unit may drop down to a lower capacity. Remember that the compressor is the highest energy consumer in an AC, and cutting down on power will result in significant savings.

2. What to Look for When Buying an Efficient Air Conditioner

One way to determine the AC’s efficiency is by checking the SEER rating. It indicates how much energy the unit consumes to distributing a specific amount of heat into your house. The higher the SEER, the more efficient the model is. Most modern brands have a SEER rating of about 18 and above, while the older ones might even have a rating below 10.

Also, look for the ENERGY STAR certification before purchase. It means that the unit has met or exceeded the required efficiency levels. An AC with a higher rating will cool your house faster and consumes less energy.

For an air conditioner to be efficient, you need to choose the right size. An oversize unit causes higher humidity levels in your house. You will thus need to run a dehumidifier which will increase your energy bills. Again, if you buy an undersized unit, it will work hard to meet your house cooling needs driving up your energy bills. Proper sizing will require you to consider other issues besides the square footage, like the ceiling height, insulation level, and the climate. It’s, therefore, a good idea that you consult a professional to help you choose the correct size.

A Wi-Fi-enabled AC will let you adjust settings remotely to save on energy further. You can schedule it to turn off when you are out of the house and on just before returning to avoid heating the home when unoccupied

3. Benefits of Using an Energy Efficient AC Unit

An efficient AC consumes less energy lowering your cooling costs. Also, if your unit operates at optimum efficiency, it’s less likely to breakdown. You will thus experience fewer disruptions and repairs. Additionally, your air conditioner will last as long as possible. You will also serve your part in maintaining the environment by using an efficient AC.

4. How to Maintain Your AC’s Energy Efficiency

You need to play your part to ensure that your AC remains as efficient as possible. Clear around the outdoor unit to prevent debris accumulation that limits airflow and lowers the unit’s efficiency.

Replace the filters after every three months or monthly if you reside in dusty areas or have a heavily shedding pet. Also, have a professional inspect your AC regularly. The technicians will help clear the vents, clean the coils, ductwork, drain lines, check the thermostat and electrical wirings.

Bottom Line
