Heating, Ventilation & Air-Conditioning

1. Eco Friendly The biggest difference between inverter and non-inverter air-conditioner is the fact that the motor of the inverter compressor has a variable speed. The speed of the non-invertor compressor is fixed. This means that it operates either at full or minimum speed. A censor in the invertor adjusts the power according to the temperature in the room, lowering the electrical consumption and saving energy.
2. Saving money Due to the sophisticated operational method of the invertor, its compressor does not work at its full capacity all the time. When the speed is lower, the needed energy is lower too and you pay less money for electricity.
3. More quite sound As the compressor motor of the inverter air conditioner does not turn on and off all the time, but keeps working at low power, the operation is more quite.
4. Longer life The technology of the inverters not only makes cooling and heating more efficient, but it also makes the air-conditioner life longer.
5. Faster Cooling/Heating Last but not least, the inverter air-conditioner is able to cool or heat your room faster than the non-inverter. This is due to the fact that in the beginning of the process, the inverter uses more power than the non-inverter and diminish the power when it gets close to the desired temperature.

Inverter vs. Non-Inverter Aircon: Pros & Cons

Inverter Pros

• Energy Efficient: The compressor is not constantly running at full power, as the system utilizes a controlled compressor that works at variable speed settings. This makes the inverter aircon a much more energy-efficient and environmentally-friendly option than a non-inverter.
• Quiet: Since it uses less power, the inverter aircon will be much quieter than a non-inverter. Also, since the unit regulates its processes according to room temp instead of abruptly turning on and off, you’ll avoid the loud start and stop sounds that occur in non-inverters. 
• Good Investment: Though expensive, the inverter aircon can be considered a good investment given its functionality, flexibility, and durability. Not to mention, its life span is much longer compared to non-inverter units. These qualities and all other aforementioned aspects make it a reliable air conditioning system worth its high prices.

Inverter Cons

• Expensive: As inverter aircons use more advanced technology, they are much more expensive than non-inverters. They also have added costs such as a higher installation fee, and have parts that are more expensive to replace. 

Non-Inverter Pros

• Cheaper and More Accessible: The non-inverter aircon’s primary pro over the inverter aircon is its affordability. Since this aircon is cheaper, it’s a much more accessible option for Singaporeans with limited income.  

Non-Inverter Cons

• Noisy: As the non-inverter aircon as built to turn on and off every time a certain temperature is reached, it can create a lot of noise that may annoy some occupants, especially if sleeping or working.
• Shorter Life Span: The frequency of the non-inverter turning on and turning off consequently speeds up wear and tear on the system, shortening its life span.
• High Electricity Bills: Non-inverter aircons are notorious for skyrocketing electricity bills due to the start-stop process of their compressor system. Mismanagement of your air conditioning habits could lead to unmanageable expenses in the long run.

Depending on your system and the environment it is in, it should be serviced a minimum of once a year, with periodic inspections up to 4 times a year. We suggest scheduling a consultation with a leading HVAC service company. Based on the age, size and usage of your system, a quality service provider can tailor a service plan to meet your budget requirements and keep your system running reliably.
