Different HVAC Components and Their Correct Placement

Heating Ventilation and Air Conditioning SystemHVAC units are standard parts of all buildings these days, with the increased need for indoor comfort. The primary determinant of your unit’s efficiency and longevity is its installation. It is, therefore, important to hire a professional during installation.

Before your HVAC installation in Knoxville, TN, the HVAC company you choose will assess your property. This assessment helps them determine the best sites for placement of various components of your HVAC system. Here are some important details about this type of project:

Handlers and Ducts

Placing your air handlers and ducts in insufficiently cooled areas is one of the biggest mistakes that affect the quality of air your HVAC unit delivers. If it’s not possible to place the air handlers in a location that can be cooled by your HVAC system, put them in the basement because it is naturally cool there. Air ducts positioned in hot areas will generally increase the temperature of the air circulating in your home interior.


Your HVAC’s registers work on the principle that cold air sinks while hot air rises. The best option for your registers’ placement, therefore, is in the ceiling so that cold air sinks to your rooms and keeps them cool. You might still opt to place the registers on your walls and floors but to maximize efficacy, there should be no airflow obstructions.

Condensing Unit

The placement of your condensing unit in the attic or basement causes re-circulation of extracted air back into your indoors. The ideal option is to place the condensing unit on a solid outdoor base. The area you choose should be shaded, but obstruction-free.
