Ductless HVAC

One of the best ways to reduce costs associated with heating and cooling is to build a high performance home. A new alternative for high-performance heating and cooling is the duct-free mini split system that offers a number of significant benefits over the traditional forced-air system.

The main advantages of mini splits are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Each of the zones will have its own thermostat, so you only need to condition that space when it is occupied, saving energy and money.

Like traditional central HVAC systems, mini splits have two main components:

  1. outdoor unit (compressor/condenser)
  2. indoor air-handling unit

A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor unit.

Why in most cases traditional HVAC is inferior to ductless HVAC

Unfortunately, the United States has fallen behind when it comes to efficiency the residential HVAC installation application. We as a nation have to be re-educated in how important efficiency is to our future existence.

The conventional installation of low rated, flexible duct work in an attic space where the temperatures reach above 140 degrees is everything but efficient and unhealthy. Partially filtered air blowing across a moist evaporator coil in a heated environment promotes constant unhealthy bacterial growth, mold and number of other allergen related issues. As much as 85% of conventional HVAC residential installations have been installed incorrectly in our high humidity environment. New construction home is filled with toxic off-gases or volatile organic compounds (VOC). Homes are built much tighter than ever before although this makes them more efficient these new homes are not receiving adequate and lack the ability to to deplete voc's.

Ductless mini splits are the innovative and most efficient installation of choice. All conditioning of the inside air is done inside the conditioned space. Only the copper line sets are existing in the harsh attic environment. These copper line sets can be insulated more effectively then the low rated R Factor of existing flexible ductwork making the installation of the ductless mini-split much more efficient with total control of temperature for each division room in a residential application as well as control heating are cooling and a particular room individually.
