Split HVAC Systems

In Arlington homes, you will typically see what is known as split-system HVAC equipment. This means that part of the HVAC system is located indoors, and part of it is located outdoors. The indoor components will consist of an evaporator coil, which is either connected to the furnace or located inside the air handler of your heat pump.

The outdoor component of a heating and air conditioning system is called a condensing unit and is made up of the condensing coil and the compressor. The compressor is the “heart” of the system because it pumps the coolant and lubricating fluid throughout the machinery. It is the hardest-working and most critical part of the system. In commercial applications in Arlington, we normally install package HVAC systems that contain all components in one outside unit.

Proper HVAC Ventilation in Arlington, VA

What do you know about your ventilation system? Here are a few facts:

  • Ventilation refers to the duct system that circulates the air in your home or business.
  • Air coming into the indoor system is called return air; air going out of the indoor component to the rest of your house is called supply air. In some cases there is very little on the return side, and it may only consist of an empty space below the HVAC closet or a plenum connected to a hole in the roof.
  • Modern Arlington building codes sometimes require returns in every room, so this can become more complex for newer buildings.
  • The ventilation aspect of HVAC is extremely important in terms of comfort, energy efficiency, equipment operation and indoor air quality.
  • There can be hundreds of feet of duct in an average-sized Arlington house, and it frequently is placed in areas such as the attic or basement where the air is not clean. If your ductwork is not perfectly sealed, you will not only lose heating and air conditioned air to outside areas but also bring dusty or dirty air into the conditioned air in your house. This wastes a lot of energy as well as creating a potentially unhealthy indoor environment.

If you are worried about your air, you can always install an air cleaner or other indoor air quality products.
