Heating & Air Conditioning Tips & Info

What is Variable Refrigerant Flow (VRF)?

VRF (Variable Refrigerant Flow) systems have been used in commercial installations for some time, but Carrier was the first to introduce the Single-Phase VRF System commonly used in homes.

Unlike traditional central air conditioning systems, VRF systems send refrigerant from a single outdoor unit to multiple indoor units (split systems). This allows you to create “zones” in your home. You can heat and cool rooms you are using without wasting energy in areas that aren’t occupied.

Energy Efficiency

Efficiency is a key element of VRF systems. Carrier’s inverter technology allows the compressor to speed up and slow down to maintain a consistent temperature without completely starting and stopping like conventional units.


In VRF systems, refrigerant is run through pipes from the outdoor unit to the indoor units – no ductwork required. So if your home was built without ductwork, you’re building an addition, or need a little extra heating or cooling in your sunroom or garage, VRF systems can be customized to meet your needs. These systems can also be integrated with existing systems in any size home providing energy savings, improved home comfort, and better temperature control.

Why Carrier?

Carrier offers a variety of indoor units including ducted, console, floor mount, and modern high-wall units in various colors to match any room décor. The units are extremely quiet and compact and can be installed with minimal distruption in a few days.

With its great efficiency, flexibility, and customizable options, it’s easy to see why more homeowners are looking to install VRF split systems.
