If you’ve been looking at air conditioning units and systems, you might have encountered inverter ACs.
There are many different air conditioning units available to homeowners, including mini splits, central air conditioners, and stand-alone units. An inverter AC is just one more type you can consider installing in your home!
But what is an inverter air conditioner, and what are the pros and cons of installing one? We’ve created this guide to help you decide on the best air conditioning unit for your living space.
What is an Inverter AC?
Also known as a variable speed or variable frequency drive (VFD) AC, an inverter air conditioner is an air conditioning system that uses inverter technology to control the compressor motor speed and adjust the cooling or heating capacity of the unit.
Unlike traditional air conditioners, which have fixed-speed compressors that turn on and off to regulate temperature, inverter-type air conditioning doesn’t shut off, but instead provides a continuous modulation of compressor speed.
Put simply, an inverter-type AC unit stays on but will increase its cooling capacity to reach the desired temperature and then decrease it to save energy.
What are the key features and benefits?
So why might you choose an inverter AC over a traditional air conditioner system? Here is our list of benefits of inverter AC systems:
Variable speed operation
Inverter ACs can vary the speed of the compressor motor according to the cooling or heating demand. This allows the unit to operate at different capacities, ranging from low to high, based on the required temperature.
The compressor adjusts its speed to match the cooling or heating needs, resulting in more precise temperature control and improved energy efficiency.
On the topic of efficiency, inverter ACs are known for their efficient energy consumption. By continuously adjusting the compressor speed, these units can avoid frequent on/off cycling, which consumes more energy each time it starts up.
Modulating the cooling or heating capacity helps maintain a consistent temperature with minimal fluctuations, thus, reducing overall energy consumption. As a result, inverter ACs can provide energy savings compared to traditional, fixed-speed ACs, especially when your unit isn’t running at maximum capacity (which is most of the time).
Lower energy bills
Due to their energy efficiency, an inverter AC can also lower your energy bills. The ability to modulate the cooling or heating capacity based on the actual requirement results in optimized energy usage and can lead to considerable cost savings over time, especially in regions with warmer climates.
Faster cooling and heating
An inverter AC can cool or heat a space faster than fixed-speed ACs. The variable speed operation allows the unit to ramp up the cooling or heating capacity as needed, reaching the desired temperature faster. This feature is particularly useful when quick cooling is needed during hot summer days.
Inverter air conditioners provide enhanced comfort by maintaining a stable and consistent temperature. They can avoid the temperature fluctuations often experienced with fixed-speed ACs because traditional air conditioners tend to overshoot the desired temperature before shutting off.
The precise control over cooling or heating capacity ensures a more comfortable indoor environment without sudden blasts of cold air.
An inverter AC tends to operate more quietly than a fixed-speed AC. The variable speed compressor reduces noise levels by running at lower speeds during periods of lower demand. This results in a quieter cooling or heating experience, creating a more peaceful and comfortable living and working environment.
Due to the absence of frequent on/off cycles, the compressor motor on an inverter AC experiences less wear and tear. The gradual modulation of compressor speed helps reduce stress on the system, leading to a potentially longer lifespan for the unit and reduced maintenance costs over time.
An environmentally-friendly alternative
Inverter ACs are energy-efficient, reducing electricity consumption, meaning your heating or cooling system will be responsible for lower carbon emissions. By choosing an inverter AC, you can reduce your home’s carbon footprint and contribute to a greener planet.
The disadvantages of inverter AC systems
While there are several benefits of inverter AC systems, they also have a few disadvantages to consider. Some of the drawbacks of an inverter AC include:
The advanced technology and components used in inverter ACs result in a higher initial price tag. However, it’s important to note that the long-term energy savings may offset the initial investment.
Complex design and maintenance
Inverter ACs are more complex in design and have sophisticated electronics, including the inverter circuit, compressor, and control systems. This complexity can lead to increased maintenance requirements and higher repair costs if any component malfunctions.
Vulnerability to power surges
An inverter AC is more sensitive to power surges and voltage fluctuations. Sudden power spikes or drops can damage the inverter circuitry and other electronic components, potentially resulting in costly repairs or replacements.
In some cases, inverter ACs can produce more noise compared to non-inverter models. While modern inverter ACs have improved noise reduction technology, it’s advisable to check the noise levels of specific models before purchasing if noise is a concern for you.
Some inverter air conditioner units may not be compatible with older electrical installations or systems. They require stable and reliable power sources to function optimally. So, if your electrical infrastructure is outdated or unreliable, you may need to upgrade or make adjustments to accommodate an inverter AC.
Size and weight
Due to the additional components and electronics required, inverter AC units are typically bulkier and heavier compared to non-inverter models. This can make installation and transportation more challenging, especially in situations where space or access is limited.
Despite these disadvantages, inverter ACs remain a popular choice due to their energy efficiency, precise temperature control, and long-term cost savings.
