Hot and cold spots in a home usually trace back to airflow imbalance. One room gets too much conditioned air while another gets too little. The causes range from improperly sized ductwork to closed or restricted dampers to return-air paths that do not match the supply layout.
Balancing airflow starts with measuring the temperature and volume of air at each register. The technician then adjusts dampers in the ductwork, checks for leaks or disconnections, and verifies that the blower is moving the right volume of air for the system. Sometimes the fix is as simple as opening a damper that was closed during construction. Other times it requires adding or modifying duct runs.
Proper airflow balancing also affects humidity. A room that gets too little air tends to be warmer and more humid. Balancing the system distributes conditioned air evenly, which keeps every room comfortable and reduces the load on the equipment.
What to Expect
- Temperature and airflow are measured at each register in the home.
- Dampers and duct connections are adjusted as needed.
- Post-balance measurements confirm even temperature distribution.
