AC Repair San Antonio

Why is One Room Hotter Than the Other?

Experiencing cold and hot spots in your house and high AC bills? There may be a problem with your air ducts that is creating air flow issues. There are a few reasons this annoyance could be occurring to your home, and luckily there are a few simple solutions. The first step is to determine the problem.

Problems in the air duct

One room may have a hot spot because of a blockage, tear or poor design with your air ducts. Cool air travels through air ducts to reach the rooms in your house. It is possible that a build-up of dust is creating a blockage that is restricting air flow to a certain room. This can be easily fixed by cleaning out the air ducts regularly. Your air duct may have also been poorly installed or torn, causing warm or cold air to leak into your attic without ever making it to certain rooms. This problem can be easily solved by hiring a specialist to inspect for air duct repair.

Design issues

Another common cause to the different temperatures you may be experiencing in your home is structural design issues. Uneven or not enough insulation in the walls or ceilings allow heat to leak in causing the room to be hotter than the rest of the house. Old windows may also be allowing heat to leak into your home. Upgrading to double-pane windows it the best way to ensure that your windows are not the source of the problem.


Change your air filters monthly and maintain clean air ducts – those are two simple ways you can prevent uncomfortable hot spots in your home, as well as avoid overpriced AC bills. However, if you find that these are not the solutions, you may need to call a professional like Champion AC to inspect your air ducts or discuss options like ductless AC units to keep every room in your home cool and comfortable.
