Ductless Mini-Splits Provide the Zoned Heating and Cooling You’re Craving!

When it comes to installing ductless systems, the correct sizing is critical. The old rule-of-thumb methods for sizing heating and air conditioning systems do not work. From our decades-long experience in the industry, we always have a good idea of the unit size a home requires. However, the only accurate method is to perform a heat loss/heat cool analysis, also known as Manual J calculation, of the entire building to calculate the exact heating and cooling requirements of a system before the final selection of the equipment can be made. We use software that performs these calculations to verify the size of the systems needed.

Frequently Asked Questions

There are many variations of the indoor units, and each company has a slightly different design for their units. Depending on your space and preference, we provide an array of ductless mini-split indoor units, such as:

  • Standard wall unit
  • Ceiling cassette
  • Floor mount
  • Mini-ducted system

Ductless mini-split systems are versions of heat pumps that use the refrigerant process to heat or cool a conditioned space. As the name implies, a ductless mini-split has no ducts, so it does not gather dust and dirt. Having no ducts also means the system does not leak expensive heating or cooling energy into your crawlspace or attic. A simple ductless system is comprised of one indoor wall unit connected by small refrigerant piping to one simple outdoor compressor unit.

A ductless system can be used to heat and cool one room only, or it can serve multiple areas of a home. One outdoor compressor can be connected to up to eight indoor units. Each indoor unit is self-contained and individually controlled. Ductless mini-splits are the perfect cooling solution for older homes that have no space for ductwork. A good example of an older home retrofit is an Eichler home with a concrete slab and no attic. Eichlers are prime candidates for multiple ductless units. In new construction, the application could be a green, energy-efficient, multi-zone system for a new home.

Heat pumps use electricity to pump refrigerant around a system. The energy used is running the pump or compressor. There are no heating elements. Heat pumps extract heat from the outside air when in heating mode or extract heat from the inside air when in cooling mode. Heat pumps can be up to 450% efficient. That means 1 kilowatt in and up to 4.5 kilowatts out. This high efficiency of the refrigerant process makes it very economical for the consumer to use electricity to heat and cool.

Variable-speed compressors are the heart of ductless systems. The speed of the compressor varies according to how much work the heat pump has to do. This further improves electrical efficiency, with up to 40% less electrical energy used than a conventional single-speed compressor. Multi-zone technology improves the system’s efficiency even more. One only needs to heat or cool the rooms you are using, and different rooms could be on different schedules.
