How to Balance your central heating system

Balancing your HVAC system involves testing to determine if your heating and cooling system is performing optimally. Otherwise, the amount of air being delivered to each room in your house may need to be balanced. Of course, the average homeowner won’t have the skillset or equipment to handle this on their own. But, if you’re noticing certain rooms are warmer or cooler than others, here are some potential solutions.

Air Distribution and Ductwork

4 Effective Ways to Balance HVAC SystemsIf parts of your house are too warm in the summer and too cold in the winter, it’s best to begin by looking into how the air distribution system is functioning. If that checks out, the way the ductwork was originally run may be the problem. Certain issues can be resolved through relocating ductwork to a new area on the plenum box. This is the air-distribution box that attaches to the supply outlet on your HVAC equipment.

Balancing Dampers

You can install balancing dampers at the outlet of every air supply drop, but this solution isn’t always practical. While this system can modify the amount of airflow to each room, it’s not commonly used in residential settings, but rather for commercial application.

Zoning Controls

4 Effective Ways to Balance HVAC SystemsThis solution allows you to intentionally maintain different temperatures in your home, even though both sections are sharing the same equipment. This HVAC system needs zone control dampers, plus balancing dampers, a zone control board, and bypass dampers to regulate a particular static pressure. Low voltage wiring ties everything together. Also, you must add extra thermostats to control the whole operation, so you can link them to the zone control board.

Booster Fans

Occasionally, booster fans are installed. For example, in the event that a room isn’t receiving enough airflow, but balancing the dampers isn’t an available option for some reason. In this case, installing a booster fan in the ductwork that serves the problem room would force more air down the line. Controlling just how much air you’re adding to the room can be tricky, though, because these fans don’t typically have multiple speed settings. The fan will also need its own electricity source.
