The most reasonable way to cool your home nowadays is through an inverter AC. While it could probably hurt your checkbook to purchase one, the cost savings that you will experience from using an inverter air conditioner system would far outweigh it.
Getting an air conditioning unit that would run efficiently for upwards of three years would be a great value-for-money deal.
You normally would not have to have your inverter repaired as often as your conventional air conditioning unit. The way it operates does not put much pressure on its compressors and other parts and therefore do not cause the unit to malfunction too often.
Aside from the lower operating costs, the efficient way that these inverter AC cool homes are another come-on. The appeal of these air conditioners lies in the consistent temperature maintained by these inverter-types. What's more, the inverter-types are much more energy-efficient – although some do not have acceptable ratings when used at full load.
Most of these inverter-types are energy efficient only at partial loads. There are information sources that could guide you through these energy efficiency ratings.
The sales executive at the appliance store should also be able to answer your questions. Doing your own research before you go to the appliance store would help you wise upon whether or not the salesperson is pulling your leg to make a sale.
