Hot and cold spots are one of the most common complaints homeowners have about their home. After all, no one likes that sudden chill when walking into a room. However, while many chalk this up to being an unique quirk of their home, these “spots” often are caused by an issue with your heating or cooling system. In this article, we’ll review what hot and cold spots are, their root causes, and how you can address them and make your home more comfortable.

What are cold spots?
Cold spots are the areas in your home—whether in your living room, kitchen, or bedroom—where you feel a noticeable chill. If you walk into a room and you immediately notice that it’s a few degrees colder than the rest of your house, you have a cold spot.
These spots impact more then just your comfort and decision to wear sweaters indoors. They’re potentially a sign that your heating system is not working right. A properly functioning, correctly sized forced-air furnace or heat pump should heat your entire home at once. “Cold” spots are an indicator that something—either the thermostat, your air ducts, the blower, or the heater itself—is not working properly.
What causes cold spots?
Here are some of the common reasons residential cold spots occur:
- Closed Registers: Check to make sure that all the registers and vents in your home are open and unobstructed. You’d be surprised at the number of heating and comfort performance issues caused by a couch or dresser being placed right over a vent.
- Blower Malfunction: In a forced-air system, the blower is responsible for “forcing” the air through your ducts to the living spaces of your home. If this blower isn’t working properly, there won’t be enough force to move the heated air to distant rooms. The result can be cold spots throughout your home.
- Heating Issues: A malfunctioning furnace or heat pump will not provide the heat needed to completely heat the home.
- Thermostat Placement: No matter what type of thermostat you have, it operates essentially the same way: it senses the ambient air temperature in your home, and then runs the heater as needed to adjust that temperature. However, if your thermostat is on an exterior wall or near a window, it may be making poor decisions. Close proximity to exterior windows and walls can distort its temperature reading.
Another root cause of cold spots, but more difficult to address in the short-term, is an undersized heating system. This is why it’s so critical that your heating installer takes accurate measurements of your home: if your heat pump or furnace is too small for your space, it will struggle to heat it evenly.
How can you address cold spots?
First, you should rule out two things:
- As mentioned above, check the registers and vents to ensure that they are set open and not blocked by furniture. Also, if you’ve been leaving the door to that room closed, that may also impact the comfort of that space.
- Second, check your air filter. If it’s clogged with dust, dirt, and other contaminants, it may not be allowing sufficient air intake to the blower.
If both of these areas check out, it’s time to bring in a professional for heating repair. We’ll need to come out and take a look at your heater, thermostat, blower, and air ducts to diagnose the problem.
What about hot spots in the summer?
The same basic concept behind cold spots also impacts your home during the hot summer months. A temperature differential between the rooms of your home is an indicator that something is not quite right with your cooling system or how cooled air is being distributed throughout your home.
