Inverter Vs Non Inverter Aircon

Inverter technology is a recent advancement in air conditioning technology. This technology has changed the working process of air conditioners and impacted on its performance greatly. Choosing between these two types of aircons can be challenging if you do not know the key differences. Let’s break down how inverter and non inverter aircons differ and which one to buy in Singapore.

 

Table of Comparison – Inverter and Non-Inverter Aircons

Below is the key difference between inverter and non inverter aircons at a glance:

Feature Inverter Aircon Non-Inverter Aircon
Compressor Speed Adjusts automatically Fixed speed
Energy Consumption Lower Higher
Temperature Stability More stable Less stable
Noise Level Quieter Louder when restarting
Initial Cost Higher Lower
Lifespan Longer Shorter

 

What is an Inverter Aircon?

Inverter is an aircon technology that can control the speed of the compressor motor. It adjusts the cooling as needed. Once the room reaches the set temperature, the inverter slows down. It does not turn off the compressor completely. This saves energy and keeps the room at a stable temperature.

In short, an inverter aircon is smart. It works harder when needed and relaxes when not.

Benefits of an Inverter Aircon

Below are the major advantages of inverter aircon:

  • Energy Saving: It uses less electricity over time.
  • Stable Temperature: No sudden temperature swings.
  • Quiet Operation: No loud on-off noises.
  • Environmentally Friendly: Less energy means a smaller carbon footprint.
  • Long-Term Savings: Lower electricity bills in the long run.

Disadvantages of Inverter Aircon

Below are the drawbacks of inverter aircons:

  • Higher Purchase Cost: Inverter models are more expensive.
  • Costly Repairs: If something breaks, repairs can be expensive due to complex technology.
  • Sensitive to Power Fluctuations: May get damaged more easily due to power fluctuations.
  • Requires Professional Installation

What is a Non-Inverter Aircon?

A non-inverter aircon works in an on-and-off way. The compressor runs at full speed until the room cools down. Then it shuts off. When the temperature rises again, it restarts at full speed.

This cycle repeats over and over. Non-inverter aircons are simpler but less energy-efficient.

Benefits of a Non-Inverter Aircon

Below are the major benefits of a non inverter aircon:

  • Lower Purchase Price: Great if you are on a tight budget.
  • Simple Design: Fewer parts mean less risk of breakdowns.
  • Good for Short Use: Ideal if you only use the aircon for a few hours a day.

Disadvantages of Non-Inverter Aircon

Below are the major drawbacks of a non inverter aircon:

  • Higher Energy Bills: It uses more electricity.
  • Noisy Operation: Compressor’s starting and stopping can be annoying.
  • Uneven Temperature: The room can often feel too cold and then too warm.
  • Shorter Lifespan: Frequent start-stop operation puts more stress on the system.

 

Inverter Vs Non Inverter: Cost Consideration

Inverter aircons cost more. But they will help you save on monthly electricity bills. In Singapore, where electricity is not cheap, these savings add up.

Non-inverter aircons are cheaper to buy. However, if you use them often, you may end up paying more in electricity bills over time.

 

Other Things to Consider while Deciding on Inverter Aircon

  • Room Size: Bigger rooms may need a stronger aircon. Inverter models handle large spaces more efficiently.
  • Usage Habits: If you love keeping your aircon running all night, an inverter model is more cost-effective.
  • Noise Sensitivity: Light sleepers may prefer inverter aircons for their quietness.
  • Environmental Impact: If you want to be eco-friendly, inverter aircons are a better option.

 

Inverter or Non Inverter – Which Aircon is Better for Singapore Homes?

Singapore is hot and humid all year round. Most homes and offices run air conditioners for many hours daily.

If you use your aircon regularly, an inverter aircon is the better choice. It saves energy, keeps the room comfortable, and runs quietly.

If you only use your aircon occasionally, a non-inverter aircon might work fine. It can be a good option for guest rooms or rental properties where use is limited.

 

FAQ

What is the main advantage of an inverter aircon?

An inverter aircon saves energy by adjusting the compressor speed instead of turning on and off.

Is an inverter aircon more expensive to maintain?

Not really. Inverter aircons are designed to last longer. With regular servicing, the maintenance cost is manageable.

How much can I save on electricity bills with an inverter aircon?

You can save up to 30-50% compared to a non-inverter model, depending on usage.

Are non-inverter aircons still a good choice?

Yes, if you use the aircon for short periods or want a cheaper upfront cost.

Does an inverter aircon cool faster?

Yes. Since it can run at higher speeds initially, it cools the room faster than non-inverter models.
