Inverter AC vs. Non-Inverter AC
In recent times, inverter air conditioners have become popular for domestic use. However, many still wonder which type of air conditioner is best for their homes. Here’s my advice:
It depends on your usage. If you plan to use your air conditioner for less than 6 hours a day and the price difference between inverter and non-inverter models is a concern, I recommend opting for a non-inverter AC. In this case, you won’t notice a significant difference in electricity consumption or your bill. However, if your AC will run for more than 10 to 12 hours daily, you’ll see a noticeable difference in energy consumption.
Advantages of Inverter and Non-Inverter ACs:
- Non-Inverter ACs are generally cheaper than inverter models. Initially, the price gap was significant, but it has been narrowing over time.
- They require minimal maintenance, mainly cleaning the indoor and outdoor units and filters.
- A well-known brand’s non-inverter AC can last up to 10 years without needing a compressor replacement, which is the most expensive component.
- A non-inverter AC might require a small gas recharge every 3 to 5 years if used continuously for 8 hours daily.
- The control circuit of a non-inverter AC can last around 5 years and is much cheaper than an inverter AC’s PCB.
- Non-inverter ACs cannot modulate the cooling cycle. They operate at full compressor capacity when turned on and stop once the set temperature is reached. This results in a constant inrush of starting current.
- Inverter ACs can adjust cooling based on room temperature and settings, reducing power consumption by up to 25% or more. The compressor doesn’t start with full current, avoiding frequent inrushes like non-inverter models.
- The outdoor unit of an inverter AC is lighter than that of a non-inverter AC.
- Inverter ACs maintain a comfortable room temperature as they continuously run the compressor to precisely regulate the temperature. In contrast, non-inverter ACs stop completely when the set temperature is reached and restart at full load when the temperature drops below the preset level.
