Uneven Cooling: Solving Common Issues

Written by Arpi’s Industries in Calgary

Uneven cooling makes it a burden just to be comfortable in your own home. Some rooms may get too much cool airflow while others hardly receive any airflow at all. If you have a split-level or multi-story home, comfort and energy problems may be exacerbated. If any of this sounds familiar, keep reading for solutions to your home comfort quandary.

Dirty Ducts and Vents

Central air conditioners need unrestricted airflow to work effectively. As airflow is pulled across the evaporator coil, it is cooled and pushed through ductwork to the rooms of your home via vents. Something as banal as dust and dirt clogging duct tubes and air vents can cause uneven cooling in your Calgary home.

Clean the supply vents and return grilles with a cloth or the brush extension of your vacuum. Duct cleaning should be handled by an HVAC professional using the right equipment to prevent contamination in your living spaces.

Leaky Air Ducts

If you have uneven cooling, chances are you have air leakage somewhere in the ductwork. Air leaks not only compromise your comfort, they waste a lot of energy.

Inspect your air ducts. Some leaks will be obvious, such as separated duct connections. More indicators of air leaks include dirt streaks on ducts or insulation and rattling noise. Seal up loose ducts with heat-resistance metal tape.

Restricted Airflow

The layout of duct runs and duct sizing when installed could contribute to restricted airflow. Improperly sized ducts won’t deliver equal temperatures to rooms — not necessarily equal airflow due to differing sizes of rooms. The result is uneven temperatures, energy problems and perhaps moisture problems. Improper duct sizing and layout must be resolved by your HVAC contractor.

To promote free airflow through your home, keep interior doors open to rooms with air vents and return grilles. Many homeowners think that by closing doors to unused rooms that they are saving energy. This is an energy myth. It actually works against your comfort and energy efficiency efforts.
