How to Eliminate Hot and Cold Spots in Your Home

Uneven temperatures in your home can be very frustrating, especially if you don’t know what’s causing them. These shifts in indoor temperature can manifest as hot or cold spots around your home. This blog from HVAC service company Schmitt Heating & Air Conditioning shares the most likely causes of any hot or cold spots, as well as how to eliminate issues with temperature fluctuations.


Improper Thermostat Placement

Your thermostat’s job is to determine how much warm or cold air to produce in order to achieve your preferred indoor temperature. However, problems may arise when the thermostat is located in an area that’s exposed to sources of heat such as windows (direct sunlight) or lamps. A simple fix would be to cover the heat sources; however, if that’s not possible, you may have to relocate your thermostat.

Dirty Filters

Air filters need to be cleaned or replaced every one to three months to ensure optimal air flow. You can perform the cleaning or replacement of the filters yourself, but it’s highly recommended that you contact your HVAC service company to do it for you. Dirt and other dust particles that are clogging your air filters put a strain on your HVAC system, resulting in uneven heating and cooling around your home.


Air leaks are caused by any gap or crack in your home’s construction. Any opening, especially those in the seals of your windows and doors, can disrupt the airflow in your home and mess with the HVAC system’s ability to regulate indoor temperature.

Faulty Vents

When installed properly, your ductwork evenly distributes heated or cooled air into your home. However, if the installation is faulty or something is blocking the vents, you might encounter problems which will manifest as hot or cold spots.
