Ultimate AC Buying Guide: All AC Features Explained

Advertisement

Summer has arrived, and the temperatures are starting to soar. Whether you’re a first-time buyer or wanting to replace an existing air conditioner, you’ll need to narrow down your options because the market is flooded with options. Furthermore, air conditioner specs resemble a technical paper and are sometimes difficult to comprehend.
AC Features Explained

Cool Mode

Most of us identify air conditioners with this setting. Your air conditioner’s compressor is turned on in this mode, and cold air is pushed into the room. The compressor will turn off and just the fan will operate when the internal temperature sensor in the AC detects that the required temperature has been attained.

On your air conditioner remote control, this is the most energy-intensive setting. The compressor will run for a longer period of time if the temperature is set lower.

Fan Mode

When the fan mode is turned on, the AC’s internal fan circulates air around the room. This is done without any cooling, similar to how a regular fan works.

The main benefit of employing the fan mode in an air conditioner is the apparent energy savings provided by the lack of a compressor. It does not, however, provide cold air; instead, it circulates or blasts air.

Dry Mode

If you live in a humid location, you’re probably familiar with the dry mode option on your air conditioner. This is your go-to option when it’s especially humid, but not too hot, and you’ve got perspiration rolling down your brow.

By turning the compressor on and off for brief periods of time, dry mode eliminates excess humidity from your space. Meanwhile, the fan is operating at a low speed all the time. When the internal humidity sensor of the AC detects a low enough humidity level, the compressor run-time is adjusted such that it is switched off.

Heat Mode

The airflow within the air conditioning unit is reversed in this mode. This implies that instead of being blown out into the surroundings, hot air is brought into the space. Outside, on the other hand, cold air is ejected.

The compressor, which is already running, provides the heated air. Instead of chilly air, the compressor now produces warm air, which is ideal for the winter months.

Auto Mode

AC Remote Features
The auto mode on your air conditioner remote control works in a similar way to the cool mode in that it aims to reach and maintain a specific temperature set point. The compressor and fan speed of the air conditioner are automatically adjusted in proportion to the current room temperature.

The compressor is switched off after the required temperature is reached, and the fan speed is automatically regulated by the AC. When the temperature deviates from the setpoint, the compressor is restarted and the fan is adjusted to attain the required temperature quickly.

After the target temperature is attained, the fan is sometimes switched off to save even more electricity.

Eco Mode

This is the mode that we all enjoy. It is now found on almost every contemporary air conditioner remote control. It works by maximizing the efficiency of your compressor and fan to attain the optimum temperature with the least amount of electricity.

Different manufacturers employ various methods to do this. Some people set the target temperature a few degrees higher than the one you choose. The compressor is shut off when the AC reaches this temperature, but the fan speed is maintained. This helps to attain and maintain the correct temperature while consuming minimal energy.

Turbo Mode

Turbo mode is the complete opposite of eco mode, and it goes all out to achieve the target temperature in the shortest amount of time. This mode uses maximum power, with the compressor and fan running at full speed. Jet, strong, rapid, or high power are all terms used to describe this mode.

As you can expect, this option consumes a lot of energy, so it’s best to just use it for a limited amount of time. This is useful when the weather is excessively hot or cold, and you can turn it off after the temperature has stabilized.

Freeze Protection (FP) Mode

This setting is also known as Low Heat, Min. Heat, or 8C. (LH). The air conditioner operates at a low power level in this mode, blowing warm air into the room. To avoid freezing points, it maintains a temperature of about 46 ° F (depending on the AC manufacturer).

This function is ideal for households in severely cold regions when the interior space isn’t used for extended periods of time. The freeze prevention mode will prevent the room’s interior temperature from approaching freezing once activated. Air conditioners are set to the lowest setting, consuming the least amount of power.

During extreme cold, this mode helps protect critical electrical equipment and water pipes. This would be impossible due to the ambient temperature being above freezing. This makes it perfect for applications such as garages or outhouses/sheds, where occupancy is low but temperature must be maintained above freezing.

Self-Clean Mode

Dirt can build up within your air conditioner over time, resulting in the transfer of harmful microorganisms into the air.

By eliminating moisture from inside your heating/cooling unit, self-cleaning or auto clean mode inhibits the formation of airborne germs. In humid areas, this mode is a lifesaver. It cleans and dries your evaporator, ensuring that your air conditioner is ready for the next use.

Your HVAC unit’s self-clean mode provides you peace of mind knowing the air you breathe is clean.

The self-clean function is available in Cool, Dry, and Heat modes on select models. When the mode is turned on, the air conditioner will operate for around 30 minutes before turning off on its own. The precise period varies by manufacturer, so consult your unit’s user handbook for further information.

AC Fan Speed

The actual component that blows cold or hot air into your room is the air conditioner fan. You may regulate the pace with which you can manage the cooling or heating of your room by using this setting.

The fan on most air conditioners has four settings: low, medium, high, and auto. The auto fan option adjusts the fan speed automatically based on the current temperature and the target temperature. To use this feature, the fan mode in an air conditioner does not need to be switched on.

AC Timer Setting

AC
Most contemporary air conditioners have built-in timers. They let you to control the duration of an air conditioner’s operation, therefore conserving energy. A particularly helpful scenario is during sleep, when you may set the timer for a few hours and the AC will automatically switch off when you are sound asleep.

Some timers function on a 24-hour clock, allowing you to program when an air conditioner must be turned on or off. Others enable you to specify the amount of hours the air conditioner will be on.

Ionizer Function

Who doesn’t want to breathe pure air? The ionizer function isn’t common in air conditioner remote controllers, but it’s still a helpful feature. When the indoor unit is turned on, a high-voltage electronic mesh is activated, which serves to ionize the air with negative ions. These ions attract dust particles and other pollutants, ensuring that they are removed from the air.

Swing Control

This option allows you to regulate the swing louver’s position. You may pick from a variety of angles to direct the airflow in the precise direction you want. Previously, only vertical swing controls were available, but now you can regulate the swing vertically as well.

There’s also an auto-swing feature that changes the angle of your AC’s vanes on the fly. The air is constantly blown in different directions as a result of this.

Quiet Mode

This AC setting is also known as the quiet mode. When the unit is set, it runs as silently as possible. Reduce the fan speed to the bare minimum to achieve this.

Standard AC Remotes

A conventional air conditioner remote control may have a display and a number of buttons for changing the air conditioner’s modes and operations. The type of display varies from remote to remote. There are now three combinations available:

Full state display: Currently, the most common form of remote on the market is the full state display. This type of display has all of the information on the screen. Temperature, fan modes, operation modes, swing positions, timers, and any other auxiliary functions your air conditioner may have are all things to consider.

Only show the current room temperature: This type of display only shows the current room temperature. These remote controls are no longer popular and can only be found on older versions. It’s more handy to have all of the options right on the screen.

No display: This sort of air conditioner remote control is most often seen in older institutions and hotels, and the only information you can see is the current temperature on the AC unit itself.

Universal AC Remotes

Have you misplaced your air conditioning remote? Are you unable to regulate the temperature in your home? Don’t worry; universal AC remote controllers are just what you need. These remotes are compatible with nearly any brand of air conditioner. This is achievable because to each AC brand’s unique electrical signature.

Smart AC Controller

Smart technologies are becoming more popular in this period, and more air conditioner manufacturers are releasing smart air conditioners. Wi-Fi capability is available in these appliances. While these devices are expensive, anybody can buy a smart AC remote control, which is universal and adds smart functionality to any air conditioner.

Unlike universal remotes, these smart remotes may add smart capabilities to your AC even if the manufacturer does not supply them. With a smart AC remote control, you can continue to function your air conditioner from anywhere as long as you have Wi-Fi. Furthermore, smart AC controls may have extra functions such as weekly scheduling or location-based controls, among others, depending on the brand and model.

Additional functions are typically not included in the remotes for such air conditioners. To access the full range of capabilities, you’ll need to download the manufacturer’s mobile app, which is usually free. If you need additional options, functionality, or Wi-Fi control, smart air conditioner remote controllers are ideal. Cielo’s Smart AC controllers work with more than 2000 different AC models.

Batteries Not Inserted Properly

Make sure to double-check the polarity of new batteries before inserting them. The negative terminal of the battery should be connected to the remote’s negative terminal, and the positive terminal to the positive terminal. The batteries should be securely fastened and not loose. Although this may appear to be self-evident, it is a fairly common cause that people overlook!

Infrared Transmitter Not Working

Your air conditioner remote controls operate by sending an infrared beam to the air conditioner. If your remote is old or has had a few droplets of liquid fall on it, the IR transmitter is likely to be malfunctioning. This is a simple problem to diagnose at home. Simply point the camera of your phone towards the transmitter and issue a command. The transmitter emits a brief blink, indicating that it is operational. If not, you’ll either need to get the remote fixed or replace it entirely.

Remote Control Error Codes

Consult the owner’s manual for your air conditioner if you see an error code on the display of your remote. It would provide a list of all possible error codes as well as troubleshooting tips. In the event that the manual is lost, the AC manufacturer’s website or support hotline may be of assistance.

Thermostat

You may regulate the cooling output using the thermostat on the device. A digital thermostat with a readout of both the set temperature and the actual temperature will be found in middle to higher-end models. While the digital readout is more handy, it has also been proven to be more accurate and maintain a more consistent temperature in the room, as well as having an automated shut down feature that cycles the device on and off to maintain the set temperature. A mechanical thermostat, which utilizes a dial to determine a higher or lower temperature based on where you turn it, is included in basic versions.

Adjustable Fan Speed

The rate at which your area cools down is affected by the fan speed of the unit. You usually have two (low and high) or three (low, medium, and high) fan speeds to choose from. The unit’s noise level is also affected by this option. This function is useful if you’re using the unit in a bedroom because it allows you to choose a lower, quieter fan speed at night.

Remote

A remote control allows you to operate the air conditioner without having to use the controls on the front of the machine. Standard remote controls allow you to adjust the temperature and fan speed, and some even have a temperature display. Furthermore, some devices include a magnetic hold on the side where the remote may be stored while not in use to prevent it from being misplaced.

Programmable Timer

A timer helps you minimize energy usage by allowing you to specify a delayed start or stop time. Timers are generally set in one-hour increments and can last up to 12 or 24 hours. When the machine is turned off, the timer decides when it will turn on automatically. Setting the timer determines when the unit will shut off if it is turned on.

Air Direction Control

Adjustable louvers allow you to choose the direction in which air is blown out of the device. When the unit is positioned in a living room, the ability to adjust the vent can prevent the unit from blowing directly on individuals who are sitting in the living room. If you’re going to use a room or ceiling fan, it’ll also help you maximize air flow in the space.

Energy Efficiency Ratio

The efficiency of the system is measured by the quantity of cooling delivered per unit of energy consumed by the air conditioner. The EER is calculated by dividing the cooling power by the unit’s power consumption. At a regular humidity level, EER is calculated. A higher EER indicates a more efficient air conditioner. When making a purchasing choice, consider the EER and the added expense of air conditioning.

Seasonal Energy Efficiency Ratio (SEER), which is an averaged energy consumption indication based on yearly power usage, is another way to represent the energy efficiency ratio.

Performance Coefficient (COP)

At a standard humidity and temperature condition, the EER is measured and reported. The EER measures the air conditioner’s efficiency under established test circumstances. Many factors influence real-world efficiency. The coefficient of performance is a measurement of the system’s real-world efficiency.

Weight and Dimensions

This one is simple to comprehend, but it needs careful planning. The air conditioner’s size may prevent you from putting it where you want it. When it comes to window air conditioning, it’s crucial to keep track of the proportions. Any extra space must be sealed off once the air conditioner is installed at the window, or the air conditioner may lose efficiency due to air leaks.

Noise Level

Ductless split air conditioners for residential usage feature an interior and outdoor unit that are connected by refrigerant pipes. Two noise levels are given for such ACs, one for each unit.

The noise level is measured in decibels, and the lower the number, the quieter the air conditioner. This figure is important to remember if you want to install air conditioning in your study room.

Airflow Rate

The volume of air circulated by the indoor unit is indicated by the airflow rate. It is measured in cfm (cubic feet per minute) or m3/min (cubic meters per minute) (cubic meter per minute). The chilly air would spread quicker if there was more airflow. Furthermore, increased airflow implies that a draft of air would be felt in the vicinity.

The airflow rates at various fan speeds would be listed on the specification sheet. Airflow and noise levels both decrease when the fan speed is decreased.

Piping Specifications

This is generally intended for installers, although it is beneficial to be aware of it. The pipe diameter is listed in millimeters and is unique to the AC model (mm).

If the height difference between the condenser (outside unit) and the evaporator (inside unit) exceeds the required height, the air conditioner will not work properly. The length of the refrigerant pipe connecting the two units is likewise limited.

Make sure that these numbers are followed when planning your mounting positions. The air conditioner’s proper operation is dependent on the pipe length and unit height difference. A pipe that is too lengthy may cause cooling losses, requiring your air conditioner to work more. To guarantee that your house has less cooling losses, choose a skilled installation to assess these properly.

Operating Temperature Range

By raising the temperature of the condenser’s coil by gas compression and then releasing the heat to the atmosphere, an air conditioner eliminates heat. However, there is a point beyond which the air conditioner will stop working correctly owing to insufficient heat exchange. Lower temperatures are the same. If the temperature drops below the freezing point, ice may form on the coils. When selecting an air conditioner, the working temperature range should be considered. You should get an air conditioner that is appropriate for the temperature in your area.
