Frequently Asked questions

What is a mini-split system?

Mini-splits are a ductless solution to heating and cooling individual rooms or spaces. They are discrete and reduce installation efforts.

Can I have a multi-zone mini-split system?

Yes! Mini-splits can be configured for single-zone or multi-zone applications. Each unit is connected to one outdoor unit.

Do I need a contractor to purchase and install my mini-split system?

You can purchase Durastar’s mini-split units directly from Build with Ferguson. However, we recommend working with a contractor to ensure you acquire the best combination of products, install the system properly, and take full advantage of the products’ warranty. Please note that warranties may be voided if not installed by a licensed professional.

What is an HVAC evaporator coil?

Evaporator coils are located inside your home and work with your air conditioner and furnace. Depending on whether you are heating or cooling a space, the coils pull in existing air to cool it or they add heat to warm it up. In essence, coils are one of the most important pieces to your HVAC system and are responsible for the heat exchange.

What is the benefit of an all-aluminum coil?

Unlike copper which may rust over time, all-aluminum coils do not. In addition, they are more resistant to micro-leaks which increases the longevity and efficiency of your unit.

What is the difference between an 'A' coil and 'N' coil?

‘A’ coils are formed using two slabs of fins – these types of coils have a surface area similar to a slab coil, however, they are installed without transition ducting. Alternatively, ‘N’ coils use three fin slabs. This arrangement increases the coil’s surface area and, therefore, accommodates more refrigerant. As a result, it operates more efficiently and generates more heat.
