Frequently Asked questions
What’s more important, HSPF or SEER?
If you live in an area where winters are mild, then pay extra attention to the SEER rating. Conversely, if you live in the north where winters are more extreme, then the HSPF value is more important.
What are the main differences between a heat pump and a mini-split heat pump (otherwise known as a ductless heat pump)?
Generally, heat pumps are integrated into your home’s central heating and cooling system. That means the heat it provides travels through ducts into various rooms throughout your home. Alternatively, mini-split heat pumps, or ductless heat pumps, distribute heat directly into the room where they are installed.
What is HSPF2?
HSPF2 stands for Heating Seasonal Performance Factor 2. HSPF2 is a standardized rating used by all heat pump manufacturers to compare energy efficiencies between heat pumps. The higher the HSPF2, the more efficient the system operates during cold seasons.
What is a mini-split system?
Mini-splits are a ductless solution to heating and cooling individual rooms or spaces. They are discreet 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. Optimize your comfort with mini-split accessories such as wifi adapters and smart thermostats.
Do I need a contractor to purchase and install my mini-split system?
You can purchase Durastar’s mini-split units directly from Ferguson Home. 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. Pair with mini-split accessories for ultimate 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 discreet 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 Ferguson Home. 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 it also secures the full extent of the manufacturer’s warranty.
