Ken's Weekly E-Tip: Ductless HVAC Systems

Ductless HVAC systems are now a preferred option over conventional ducted systems in many parts of our service territory. They have proven to be more efficient and less timely to install. Here are some valid reasons why a ductless split system will help reduce cooling and heating costs.


How Do Ductless Split HVAC Systems Work?   

Similar to traditional air conditioning and heating systems, a ductless split system consists of an outside compressor unit. Manufacturers incorporate a DC inverter compressor that can run at various speeds, depending on a home's heating or cooling needs. This technology results in lower operating cost and increase comfort.      

Indoor air handlers replace duct work runs. Each unit has an evaporator coil and an air handler that delivers heating and cooling to each specified area. Zoning can be accomplished by varying the temperature in any room for added comfort and energy savings.


Systems Benefits

A ductless split system comes with many benefits to homeowners including the following:

  • No ductwork to install or maintain.
  • Installation of the indoor air handlers is easy and does not require major changes to your home.
  • Efficiency increase with no duct loss.
  • Indoor air quality increases because because there are no ducts to collect dirt and molds. 
  • Inverter compressor technology use less energy than traditional compressor technology.
  • Ductless systems are less noisy than traditional systems.



Up to four indoor blower units can be connected to one outdoor compressor. Candidates for such applications are homes with radiant floor or baseboard heating systems, and new additions. 

The installer must correctly size each indoor unit and determine the best location for its installation. Over-sized or incorrectly located air handlers can result in short cycling, which wastes energy and does not provide proper temperature or humidity control. Too large a system is more expensive to buy and operate.
