How to Solve Uneven Home Cooling Issues


Factors that can lead to uneven home cooling include ductwork problems and even dirty air filters

If your home suffers from uneven cooling, you’re not alone. Many people find that air temperature in their homes differs from floor to floor, and even room to room -- sometimes significantly.

Fortunately, there are simple solutions to tackling some of the causes of uneven home cooling:

Look for blocked vents

Blocked vents and registers can be a source of uneven cooling in your home. Move any furniture that may be blocking your vents and registers from properly circulating cool air. To remove dust and debris buildup, use a vacuum with an attachment.

Switch your fan settings

Thermostats have a fan switch that toggles between “on”, and “auto”, while more modern models may have additional settings. Switching your fan to the “on” position will keep air circulating after the cooling cycle goes off. This will help to continually circulate the air in your home and even out temperatures between floors.

I recently moved into my home 6 months ago and wanted to have the AC and Furnace checked out so I got a maintenance plan through the Reliance website. I couldn't have been more pleased with the service Mario (Badge #2575) provided. He performed a deep inspection of both my AC and furnace and gave me best practices on how to keep things running efficiently. He took the time to check CO2 readings and even went above and beyond recommending options in the event of replacement. He was genuine and honest enough to let me know I was good with what I have now and provided additional information for energy efficient procedures moving forward. I truly believe I made a wise decision and can't thank both Reliance and Mario enough for helping me protect my home for years to come. Thanks a bunch!!"

Check for a dirty air filter

Dirty furnace air filters can restrict or slow the flow of air, thus reducing the amount of cool air delivered throughout your home. Always clean or replace air filters as recommended by the manufacturer.

Add attic insulation

If your home lacks sufficient insulation in the attic, you may not be getting the full benefit of your air conditioning system. Your attic’s insulation serves to keep cool air in and hot outside air out, and a lack of it can create a noticeable difference in temperature between the upper and lower levels of your home. If your attic is unfinished, have insulation placed between the floor joists. If it’s finished, install home insulation just as you do for regular living spaces – between studs and rafters of exterior walls, and along the ceiling.

Inspect for leaks in duct work

Air leaks in your duct system can rob certain rooms or areas in your home of cool air. Plus, ductwork leaks can make your AC work harder to compensate for the escaping air, leading to even more problems. Have a professional inspect your ducts to determine whether leaks are contributing to the uneven cooling in your home.
