Is a Ductless Mini-Split HVAC System Energy Efficient?

Perhaps your home in Myrtle Beach, SC, has ducted heating, but it won’t reach a shed or another outbuilding. Perhaps your home doesn’t contain ducts to begin with, and you’re wondering if you want the hassle of having them installed. Here’s how ductless systems can provide energy-efficient heating throughout the fall and winter for one or every room of your house.

Mini-Splits Transfer Heat

Just like a heat pump, a mini-split transfers heat from outdoors to warm the indoors rather than generating heat by electrical resistance or the combustion of a fuel. This makes it the more energy-efficient choice when compared to a furnace.

No Ducts Means Less Energy Waste

Another thing to keep in mind is that since they don’t use ducts, mini-splits cut down on the amount of heat that escapes from the system. The U.S. Department of Energy says that around 30% of all HVAC energy escapes through such leaks.

You’ll Save Money Through Zoning

Let’s say that your home only needs a few rooms heated. Rather than going to the trouble of installing ducts, simply purchase a group of mini-splits. One outdoor compressor can hook up a maximum of four air handlers.

The result is that you can have up to four rooms, each with its own mini-split and programmable thermostat, which every household occupant can adjust according to their temperature preferences. Occupants can shut off the mini-split when they leave a room, which is obviously not an option with central heating.

Inverter Compressors Boost Efficiency

With any HVAC system, a lot of energy goes into starting the compressor, but many mini-splits come with an inverter compressor that avoids shutting off completely. Rather, it slows down after reaching the set point, speeding up again when the temperature drops.

At Warren-Hay Mechanical, we boast a wide range of ductless systems for homeowners who are contemplating an installation, so call today for an appointment. Our service techs are ready to help you save money on heating this fall.
