The registers are very important air vents that deliver cold or warm air from your HVAC system and into your home. As you check on each register, make sure that it is open and free from any obstruction that could restrict proper airflow like fixtures, furniture or curtains.

Also, make sure that the registers are clean and that no debris or dust build-up is blocking the flow of air.

Using manual thermometers or digital temperature sensors, take note of the temperature of each room. Place the thermometers away from the registers and let it sit there for at least an hour before reading the final temperature.

Step 4: Using Duct Balancing Dampers

Duct balancing dampers are used to adjust the temperature of rooms that are hotter or colder than another. By slightly closing or opening the damper in the duct, you can regulate the amount of hot or cold air coming in the area and so as the temperature. The change in the room temperature does not happen drastically as you adjust the position of the dampers, wait for at least another hour before checking the changes with the thermometer.

While you’re doing this, remember to keep your thermostat in one temperature that you’re comfortable with. That will be your guide in finding the perfect temperature and balance. Changes must be done into the dampers and registers and not the thermostat.
