Cold air is denser than hot air. Therefore, when cold air is introduced in any room, it sinks to the bottom while warmer/hotter air rises.
Contractors who provide air conditioning installation Cypress, TX, opt to install air conditioning units at the top to increase their efficiency. When cold air is given out of the AC, it naturally sinks to the room’s bottom.
The hot air is then raised to the top and can be sucked in by the air conditioner. This allows the air conditioner to lower the air temperature in the room instead of just one section.
