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 a multi-zone ductless unit?
A multi-zone ductless unit offers customers a duct-free solution for whole-home heating and cooling. Like mini-splits, these systems have one outdoor unit, however, the outdoor unit connects with up to six indoor units for total comfort.
Where are mini-split units mounted?
Mini-split units offer customers flexibility in more ways than one. They can be mounted on the ceiling, wall, or floor. In addition, with an air handler, mini-splits are simple to integrate into existing ductwork.
Are mini-split units loud?
Thanks to their DC motors, inverter compressors, and compact design most mini-split solutions offer quiet operation and discrete mounting options. Before purchasing, check the unit’s decibel rating (dB)as a reference to compare units.
Where can I buy a mini-split air conditioner?
Durastar’s mini-splits are available for purchase through Build With Ferguson. Although these ductless air conditioners can be purchased directly, we recommend working with an HVAC contractor. Not only does this ensure the most suitable combination of HVAC products for your application but also it secures the full extent of the manufacturer’s warranty.
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.
