Uneven cooling in your home could be a sign that there’s a problem with your HVAC system or an issue with your home. Identifying the root of the problems early and taking action will increase your comfort and could reduce energy costs this summer.
Dirty air filter.
An overly dirty air filter will reduce the amount of air blowing through the ductwork. Rooms that are at the ends of the duct runs may not get enough conditioned air to cool thoroughly. Installing a clean filter will increase the airflow.
A/C is too small.
The cooling system may be too small for the home. If some rooms are uncomfortable on excessively hot days, the system may be too small. Options include replacing the entire system or adding a ductless mini split heat pump to the inadequately cooled areas.
Ductwork can develop leaks at any time. If rooms that were comfortable in the past suddenly become uncomfortable, there may be a breach in the duct. Other signs include excessive accumulations of dust around the registers and stuffy rooms.
Rooms that are too hot may not have enough insulation in the exterior walls or the attic. If you have loose insulation in the attic, it may have shifted due to high winds. Wet insulation from a roof or exterior wall leak also reduces the effectiveness of insulation. You may need to inspect the attic insulation or look over the exterior wall for signs of water damage.
Excessive solar heat gain through the windows.
Dual pane windows that lose their vacuum will emit much more heat. Over time the seal between the glass panes weakens, which destroys their ability to block heat transfer.
Besides uncomfortable rooms, you may notice fogging between the glass panes. Unless you can find a window specialist who guarantees repair work, it’s better to replace the windows than try to reseal them.
