How do I balance my central air conditioner?

Here's how to balance your central heating system:

1. Start at the furnace unit and follow the main ducts outward, looking for small levers on the side; these are the handles for dampers.
2. Place thermometers in the rooms in question, away from registers and cold-air returns, and all at about the same height from the floor.

Related Question Answers

Does closing vents help AC?

Closing the vents doesn't do it any favors. In fact, instead of helping the air conditioner cool less, closed registers force the same amount of air through other ducts. This builds pressure in the system and makes your HVAC system work harder to distribute the air where you need it.

How do I redirect my air conditioner?

A typical HVAC system delivers climate control via multiple zones by using an automated zone damper or duct damper. Only by using an actuator-controlled automatic zone damper can the system regulate the amount of air the HVAC system produces. Actuators in HVAC systems control the dampers.

Why are some rooms in my house colder than others?

If some rooms are warmer or colder than others, this is usually just a matter of balancing. Meaning adjusting the airflow to each room so they all even out. If a room is heating or cooling much quicker than other rooms, the airflow can be reduced to that room to even things out, also sending more air to other areas.

Do all ducts have dampers?

The duct damper is located in an air duct and blocks the flow of warm or cool air into building rooms. It has nothing to do with venting flue gases up a chimney. When heating or cooling are not needed in that building area or zone, the duct damper remains in the closed position.

What is air balancing in HVAC?

Problems like a fan clogged with dirt, a dead motor, a loose fan belt or a stuck wheel can all cause your blower to not work properly. These problems can keep the blower fan from blowing enough air out of your vents to keep you cool. Your evaporator coil needs air to blow over it to complete your AC's cooling process.

Is it OK to close vents in unused rooms?
