Ductless Mini-Split Comfort & Efficiency

Ductless mini-split air conditioners  & heat pumps are a great option for retrofit add-on to homes with “non-ducted” heating systems, such as hydronic (hot water heat), radiant heat, or baseboard electric heat. Ductless mini-split air conditioners and heat pumps can also be a good choice for supplemental heating and cooling in rooms or additions where installing duct work is not practical

Like standard air-source heat pumps and air conditioners, ductless mini splits air conditioners and heat pumps have an outdoor compressor/condenser and an indoor air-handling unit. The outdoor and indoor units are connected by a power cable, refrigerant tubing  and a condensate drain.

Ductless Mini-Split – Advantages

Ductless Mini-Split Air Conditioner - Heat Pump

Mini-Split air conditioners and heat pumps are small in size and provide great flexibility for zoning or heating and cooling individual areas of the home. As many as four indoor air-handling units can be connected to one outdoor unit and they can operate independently, effectively creating four zones. Each of the zones has its own thermostat, so you need not to condition areas when not occupied. This will save energy and money.

In many cases, ductless mini-split heating and cooling systems are easier to install than some other types of systems. The hook-up between the outdoor and indoor units usually requires only a three-inch hole through a wall for the connection lines. If necessary, you can locate the outdoor unit as far away as 50 to150 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a house, but locate the compressor in a more convenient or inconspicuous location on the outside of the building.

Ductless Mini-Split Floor Level UnitCompared to other add-on heating and cooling systems, mini-split air conditioners and heat pumps offer great flexibility and performance. There are several options for indoor air handlers that can be suspended from a ceiling, mounted flush into a drop ceiling, or hung high or low on a wall. Most indoor units are only about seven inches deep and have sleek, high tech-looking design. Most also have a remote control to make it easier to control the system.

Ductless Mini-Split – Disadvantages

Ductless mini-split air conditioners and heat pumps will cost a little more than some systems, but most have extremely high efficiencies, leading to  lower operating costs which can help offset the initial expense.

Installed costs of ductless mini-split air conditioners and heat pumps can vary widely, depending on the size and installation requirements. No worries though, we will visit your home to help you decide on the best indoor unit configuration location for installation. Most new models use inverter technology, meaning that they adjust their capacity to the heating or cooling requirement. This is ideal when looking at a heat pump option, as you can provide additional capacity for heat, without compromising air conditioning performance.

The appearance of the indoor part of the system is an issue for some people. While less obtrusive than a window room air conditioner, these units don’t have the built-in look of a central system. There must also be a place to drain condensate water near the outdoor unit or install an internal condensate pump. Typically, the best location is on an outside wall when these lines can run directly to the outdoors.
