Are you shopping for a reliable, reasonably priced home comfort system? If electricity is the better or only choice available to you, a central heat pump or ductless mini-split could be a convenient option. Both systems function on electric power and run in heating and cooling modes for year-round comfort. So, have you made your choice? If you're still trying to decide, get the details about each HVAC system to help you determine the right fit.
What Is a Heat Pump?
A heat pump is a type of central climate control system. Different from a furnace, which creates usable heat for the home by combusting a fuel source, a heat pump moves heat from one place to another. In the winter, it pulls out heat energy from the air outdoors and redirects it inside. Then, a built-in reversing valve will allow it to complete this process backward in the summer, behaving the same as an air conditioner to transfer heat and humidity from indoor air and vent it outside.
What Is a Mini-Split?
A mini-split works on the same principle as a heat pump. Actually, it is a kind of heat pump — just without the ductwork. This is why it’s called a “ductless” system. A mini-split is designed as a ceiling- or wall-mounted unit with a built-in air handler. This indoor component links directly to an outdoor condensing unit through a tiny hole drilled in the wall. Multiple indoor units can connect with a single outdoor unit, providing whole-home comfort with no ductwork required.
Making Your Decision
Below are significant points to consider when choosing between a heat pump and a mini-split for your Nashville home.
Ductwork & Installation
If your home is already heated and cooled with a traditional furnace and air conditioner, the necessary ductwork infrastructure is already in place. In this situation, installing a heat pump is probably the more practical option.
However, if you live in an older home or have just made an addition, you might not have ductwork in reach. In this case, adding a mini-split is much less complicated and is more affordable than putting in the ductwork required for a heat pump.
Unit Control
Heat pumps are managed in a way similar to most other central heating and cooling systems: by setting a wall-mounted thermostat installed in a accessible location. Having said that, ductless mini-splits have a remote that lets you control each wall-mounted unit from anywhere in the room.
Zoning
If you’re happy with adjusting the temperature throughout the house using a single thermostat, zoning may not be worth the effort. If it is, you can increase home comfort and save energy by heating and cooling separate rooms independently.
Such ‘zoned’ temperature control can be added into a central heat pump system by setting up multiple thermostats and ductwork dampers. But it may be simpler and more practical to install mini-splits in rooms with precise temperature demands, whether they’re heated and cooled by a central HVAC system or not.
Design Flexibility
Heat pumps don’t focus on flexibility. Instead, they can replace your existing furnace and air conditioner and supply whole-house comfort through a network of air ducts.
Mini-splits have more options for where you can put the unit. You can add one in a single room that you would otherwise find tough to keep comfortable. You could mount one in a modified garage or other home addition without adding more ductwork. You can also install a mini-split air handler in each room, all connected to the outdoor condensing unit for affordable operation.
Energy Efficiency
New heat pumps are more efficient than ever. There are even cold-climate versions available for a performance boost at low temperatures.
Even so, ductless mini-splits are generally more efficient because they don’t suffer the energy losses connected with leaky ductwork. A typical home loses more than 20% of the air traveling through the ductwork to inadequate air sealing or a lack of insulation. This suggests that a mini-split is likely to supply the same quantity of hot or cold air at a lower cost.
Appearance
Heat pumps look almost identical to central air conditioning units. The outdoor cabinet is nearly indistinguishable, and the indoor air handler sits concealed within a utility closet or space in the basement.
In contrast, mini-splits are easier to spot. The air handlers come in sleek jackets designed to be inconspicuous, but they are clearly visible in any room in which they are displayed on the wall or ceiling.
