The most cost-effective part of a 3.5 kW reverse cycle air conditioner is, you have to pay only for a single unit that performs two functions whenever required. You can turn on their cooling mode during summer to keep your rooms cool. There might be a requirement of both in every alternative day; hence having a single standalone unit will solve the purpose. You need not have both heater and air conditioner in the same room. Apart from that, a reverse cycle air conditioning system can control the moisture level of your house and it can eliminate the dust particles from its ducts to keep your rooms neat and clean.
