How to choose an efficient air conditioner? (buying guide)

Split system air conditioners

Energy efficient 

An energy-efficient will bring you enormous benefits, especially when it comes to power consumption and money. Often you will find AC units with energy efficiency ratings. Try to pick a 5-star AC.

Maintenance and cleaning 

Yes, maintenance is essential since it has everything to do with performance, efficiency and service failure.

Some companies offer after-sale service that comes with free or partly-charged maintenance. Pick the best one!

Room capacity 

This is another important factor to think of. You should buy an AC with a cooling capacity that matches your living area. Buying an AC that offers more or less capacity, you end up paying more and get less.

Noise

Last but not least, if you are a noise-conscious person, take a look at the noise level. Try to buy a unit with low noise emission, ideally below 45 dbA.

Best air conditioner brands

portable air conditioner

Needless to say, air conditioner brands are one important factor when choosing the best AC units. Below is a list of my highly recommended brand names for each type of air conditioner.

Split system air conditioners

Split system air conditioners refer to a type in which the unit consists of two separate parts. They often come with high SEER values and are quite cheap in terms of fixing or maintaining.

You can find split system AC very where, but Pioneer, Klimaire, Senville, and MrCool are places where durability and performance are ensured.

They are experienced manufacturers and very well-known for high-quality products as well as great customer services.

Portable air conditioners

Those who make portable air conditioners I entrust are Midea, Honeywell, SereneLife, and hOmeLabs.

Midea is the newest company on the list but its products are highly competitive. You can find a vast price and size range from these manufacturers.

Windows air conditioners

Window air conditioners require a high level of precision, which you can find in products of LG, TOSOT, Friedrich, and Frigidaire.

Both quality and price are exceptional. Plus, they constantly upgrade the technology used in their products, thus enhancing user experience immensely.

FAQs

window air conditioner

Are new AC units more efficient?

When it comes to the definition of efficiency, there are two ways to look at it.

An efficient cooling system means that it functions perfectly and at the same time use far less electricity than a conventional one. Also, it could be process-efficient, which means an AC unit excels at cooling your home.

Compared to a used AC unit, a new one always gives you more benefits, and being efficient is one of them. Most recent AC models adopt a SEER rating, referring to the cooling output of the system. Models with high SEER ratings often are effective.

10 years ago, the standard SEER rating was around 10, but new AU units offer that rating of at least 14. Some are as high as 20 or more.

Is it cheaper to leave the air conditioner on all day? Is it better to turn off your air conditioner at night?

There is a dilemma that most homeowners face: how to optimize the AC’s energy consumption.

An AC unit often offers 2 types of setting: on – auto, and on-off. Which one is more beneficial?

The on setting means that your AC circulates air without disruption. On the other hand, at the auto setting, the AC will automatically shut off once it reaches the set temperature.

Now, both have their benefits. However, if energy usage is what you care for, you probably want to turn off the AC at some points during the day.

You can choose to turn it off at night or during work (not ideal if you work from home). Your AC reaches its most efficient when it is working at full speed. So after cooling the room down, you don’t need to leave it on.

How can I reduce my AC electricity bill?

There are a few ways to reduce your AC electricity bill.

You can first try to reduce the frequent use of the AC unit. Try not to leave your AC on the whole day. You can put your AC on a timer so that it shuts off automatically at night. You can buy an energy-saving AC unit to make sure that energy consumption isn’t overwhelming.

If you use AC in summer, make sure that you close the curtains during the heating peak of the day. In winter, allow the sun to heat your house.

Last but not least, you should schedule frequent AC maintenance. Check the air filters and coils in the cooling system and replace or clean them if needed. You should maintain your AC a few times per year.

Why is AC not cooling enough?

Did you waste money on a poorly performed AC? Here is why.

  • Maintenance

Yes, one of the prominent reasons to account for poorly functioned AC is maintenance. A blocked air filter can result in weak airflow, thus your AC isn’t able to cool the room as expected.

You need to clean your cooling coils too since dirty coils prevent airflow. There are indoor and outdoor coils. Either of these two is dirty, it will greatly reduce the AC’s ability to blow cold air.

  • Refrigerant leak

You can schedule a check-up to make sure there is no refrigerant leak. The leak isn’t dangerous, but it prevents your air conditioner to move heat around the house.

  • Compressor

The AC compressor is another factor to blame. The compressor is in charge of refrigerant’s optimal pressure. A malfunctioned compressor will block heat from circling.

  • Old AC

An old unit, once reaches the end of its lifespan, can’t cool off as easily as before.

  • Settings

Maybe you set the thermostat in the wrong setting. If the AC is at on mode, rather than auto, it will just blow air even though you don’t need it. You could change the setting into auto and see if there is any difference.

How can I improve my AC cooling room?

Want your room to cool down faster? I have some tricks for you.

  • Cover window glass with curtains or thick, soft materials to prevent the sun from its peak.
  • Consider using a dehumidifier. A unit can remove 70 pints of water per day, assisting your AC to cool down the room.
  • Turn off unused incandescent lights
  • Close up unused rooms.
  • Consider using a ceiling or normal fan.
  • Do not cook or use dryers in an AC cooling room.

How can I make my air conditioner cool faster?

If you want to optimize your AC’s energy usage, there are a few things you should keep in mind

  • Regular maintenance is important. Your cooling system, once taken care of, will easily reach its peak performance and effectiveness.
  • Don’t touch the thermostat. Reducing the temperature will not make the room cool faster. A cooling system is a consistent machine. It cools down at the same rate regardless of the temperature setting. So just leave the thermostat as it is.

The bottom line 

Using the most efficient air conditioners not only improves your quality of life, upgrade your cooling experience but also reduce the cost of operation. It is a non-negotiable choice that you have to make as winter or summer approaches.

Hopefully, this article has fulfilled its job to help you make up your mind on which AC unit is suitable for your preference and budget.
