Looking into a VRF system

I just recently started looking into different types of heating and cooling systems. I looked into furnaces, boilers, heat pumps and air conditioners but wanted something more compact. I came across Variable Refrigerant Flow or VRF systems. Although I’d never heard of this type of equipment, the technology has actually been around for decades. Over the last five years, it has become increasingly popular in big cities where space is at a premium. VRF systems use outdoor condenser units with small air handlers that can be independently controlled. The name refers to the equipment’s ability to control the amount of refrigerant flowing to each of these small air handlers. It’s capable of providing cooling as well as heating and can even offer both simultaneously in different areas of the house. One of the many benefits of a VRF system is energy efficiency. It is designed to supply exactly the amount of conditioned air needed for the current demands, allowing it to run less often and at lower capacity. It’s also capable of capturing heat from the cooling process and reusing in other areas that require heating. The set up of a VRF system puts the condensing unit outside, keeping noise to a minimum. The indoor air handlers are very small and offer much quieter operation than a traditional air conditioner or heater. I like that I can have air conditioning in the living room while heating the upstairs bedrooms. The system’s compressor detects the exact requirements of each zone and delivers the perceived amount of refrigerant needed to maintain ideal comfort. As a result each space is always the right temperature, with no hot or cold spots. It also helps with excess humidity.
