Many homes and businesses require an efficient heating and cooling system to maintain comfortable indoor temperatures. But most people are only familiar with traditional HVAC systems that run on ductwork, not knowing that there’s a better alternative with VRF—or variable refrigerant flow. Here’s a guide that explains how this system works and its benefits.

How a VRF System Works

Similar to conventional centralized air conditioning systems, VRF systems depend on refrigerants and use outdoor condenser and fan coil units to maintain indoor temperatures. However, the likeness ends there. VRF systems are ductless and involve multiple smaller air handlers that individually control temperatures within separate areas—or zones—inside a building. And, unlike traditional centralized systems, some VRF models can also provide heating and cooling simultaneously.

Why Choose a VRF System?

Compared to heating and cooling equipment that requires ducts, VRF systems are more energy-efficient. They provide the exact amount of cooling required for current conditions, making them run less frequently and at lower capacity. Since the ductless units capture residual heat from the air during cooling, they can redirect heating to areas that need warmth. With this system, room temperatures can be easily adjusted according to preferences.

Because of its ductless flexibility, a VRF system can be used in both residential and commercial properties. Another benefit to installing a VRF system is its quiet operation. Outdoor VRF units are not designed with noisy compressors like a typical air conditioning system, and they emit very little sound when you turn them on.

What to Consider Prior to Installation

Although a VRF system weighs less and is relatively easy to install compared to conventional HVAC systems, you still need a professional to get the job done. HVAC contractors will calculate the appropriate heating and cooling requirements for your space so they can recommend the right size air handlers. While VRF systems may set you back more up-front, bear in mind that you’ll save more on energy costs and repair bills in the long run.
