Return air location
The return air is the "in-hale" of your HVAC system, filters will always be installed on this side of the system. Location, location, location! We as HVAC professionals must determine best location for application. For example, if you live where it's freezing six months a year we would recommend installing a "cold air" return lower to the floor to aid with the heating process. Or, if you live in Houston, Texas in the summertime where temperatures can reach 116 degrees we would recommend "hot air" returns mounted on the ceiling or high on a wall. Thermostat location must also be taken into consideration.
"Hot air"Return-airs can be an eyesore for some customers, building code allows us to recess "hot air" return-airs to ceiling-wall furr downs. It creates an infinity ceiling look that is a fantastic transition into a beautiful painting. Most homes have metal grills that hold the return air filters, a clean filter allows for more air volume to pass the air conditioners evaporator coil which means quicker thermostat satisfaction which means you save money!
"Cold air" return airs are generally floor mounted or installed low-wall and is crucial in an efficient winter. The downside is that they trap heavier particles due to location and clog quicker, but they are easier to change since no ladder is needed.
