Long-Term Financial Benefits of Inverter Air Conditioners

During the Indian conditions, air conditioners tend to work extensively and significantly impact the household energy cost. This renders the decision on fixed-speed or inverter AC a cost factor. A fixed-speed unit works at full power, thus resulting in spurts of electricity consumption whenever the compressor is on. Conversely, an inverter AC dynamically adjusts its variable-speed compressor, keeping it at the required temperature and therefore not turning itself on and off all of the time. This process will enable saving power up to 30 to 50 percent over a traditional unit. These savings on the electricity bills are normally huge and in the long term can compensate for the increased cost of obtaining an inverter AC.
