Why Are There Hot & Cold Spots in My Home?


Do some rooms in your home feel much hotter or colder than the others? Is your bedroom a sauna while the rest of your house is cool as can be? This problem is more common than you might think, and it can be caused by a number of issues. The key to solving your dilemma is determining the exact cause of the problem. Keep reading to discover the possible reason for the hot and cold spots in your home.

Damaged Ductwork

Your ductwork is responsible for evenly distributing heated and cooled air throughout your home. Installed in your attic, it carries temperature-regulated air from your HVAC unit and distributes the air through the various air registers in your home. When the ductwork forms cracks, holes, loose joints, or any other forms of damage, it can allow non-temperature-regulated air from your attic to enter the ducts and your home. For example, during the summertime, hot air from your attic can sneak into your ductwork while it works to distribute cool air inside. This can result in both hot and cold air coming into your home.

Closed/Blocked Registers

During HVAC operation, each of your air registers needs to be completely open, with no obstructions (such as cabinets or curtains) blocking them. Closing or blocking your air registers prevents temperature-regulated air from entering that room and results in uneven heating or cooling.

Incorrectly Sized HVAC Equipment

Installing incorrectly sized HVAC equipment can cause a number of problems in your home, including uneven, inconsistent heating and cooling. If the unit is too small, it will have to work extra hard to heat or cool your home, often falling short and leaving certain areas warmer or cooler than others. If the unit is too large, certain areas in the home might be heated or cooled too much.

Direct Sunlight

Do certain rooms in your home get a lot of direct sunlight? This can result in those rooms being a lot warmer than the rest of your home. This issue can be resolved with shades, blinds, an awning, or window tint.

Air Leaks

Due to insufficient insulation or gaps and cracks around windows or doors, air can seep in from outside, causing hot and cold spots. Any gaps or cracks should be sealed off, if possible.

Clogged Air Filters

Temperature-regulated air from your HVAC system passes through an air filter before being distributed throughout your home. This air filter traps contaminants such as dust, dirt, and dander, and will clog over time. Clogged air filters can restrict airflow and put a lot of strain on your HVAC system, resulting in uneven heating or cooling.
