Which AC Units Are Energy-Efficient?

People need their AC units to be energy-efficient because nobody wants to spend too much on their electricity bill at the end of the month. Energy efficiency also benefits the Earth as it can cut carbon footprints and greenhouse gas emissions, especially if your electricity comes from fossil fuels. The question is, which AC units are energy-efficient?

Energy-efficient AC units must have several specifications and features such as:

1. Energy Star Label

The blue Energy Star label indicates that the appliance is energy-efficient. Energy Star is backed by the government to make it easier for people to choose environmentally friendly appliances. The US Environmental Protection Agency has set strict criteria for an appliance to earn Energy Star certification.

Energy Star appliances generally do not cost more than other appliances, but their energy efficiency can help you cut costs on electricity by more than $100 per year.

2. High SEER or EER Ratings

Both SEER and EER are parameters that measure how efficiently an AC unit consumes energy. SEER stands for seasonal energy efficiency ratio, while EER stands for energy efficiency ratio. Both ratios are measured in a controlled environment by the Air Conditioning, Heating, and Refrigeration Institute (AHRI).

SEER accounts for the starts and stops of the AC unit in various temperatures. Meanwhile, EER ratings are based on the steady state of an AC. Hence, the SEER ratings are more important to consider if you live in the area where summer temperatures go up and down. But if you live in a more tropical climate, EER ratings will help you more. However, both ratings usually follow each other.

3. Correct Size

Size does matter when it comes to an AC unit. An undersized unit will fail to reach your ideal indoor temperature, putting all the energy consumed to waste. On the other hand, an oversized unit will consume too much energy and overchill your indoor air. If you are not sure how to determine the right size AC unit for your house, you can ask your dealer about it.

4. Power-Saving Modes

Some AC units provide various modes and features that allow you to adjust how the unit works. Night mode, power-saving modes, and motion sensors are some of the most popular features in an AC because they help to create comfortable temperatures while consuming less energy.

5. Proper Maintenance

A lot of people underestimate the importance of regular maintenance of their AC units. Little do they know that even a simple problem like a dirty filter can reduce the machine’s efficiency and cause it to overwork. Your electricity bill will gradually increase, but you might not notice it until a few months later. Changing filters and inspecting the ductwork are important maintenance activities to do regularly.

Aside from the AC unit itself, there are still a few things you can do to increase its energy efficiency. Insulating your house properly and investing in a programmable thermostat could also contribute a lot to keeping your AC consumption to a minimum.
