Your furnace should deliver a steady and even flow of heat throughout your home. Hotspots, which are certain areas that are hotter than the rest of the house, are not just a random occurrence. There is a reason for the problem, and it's essential you get to the bottom of the matter.

1. Area Location

Certain areas are more prone to greater temperature fluctuations. For example, if you have a small room in your home in the path of the sun, without window coverings, the space is naturally going to feel warmer than the rest of the house. When you add in the heat from the furnace, the temperature imbalance will only increase. In this instance, the most practical solution is to install window coverings.

2. Register Design 

Pay attention to the design of the registers as well. For example, if the hot spot is also a room that has more registers than other similarly sized areas in your home, the room is going to feel warmer because there is also more heat flowing through the space. Unfortunately, there is little you can do in this instance, as closing some of the registers can cause a pressure buildup that might slowly damage your furnace.

3. Duct Issues

If the ducts in your home have not been cleaned in a while, a lack of maintenance could be to blame for your hot spots. For example, say the ductwork in your bedroom is full of debris, but there is less debris in the ductwork in your bathroom. The more debris, the lower the amount of air that can flow through the ducts, so, by default, the area with less debris might feel warmer. Schedule a duct cleaning to eliminate the issue. 

4. Sizing Concerns 

If your furnace is not sized correctly, you might also run into hot spots. A furnace that is too big for a home will heat a house too quickly, but also create hot pockets at the same time. So, as a result, some areas of your house will feel warmer than others. However, a furnace that is too large can also cause your energy bill to increase. If the furnace was already installed when you moved in, it might be a good time to start looking at a replacement option.

If you have hot spots in your home, contact an HVAC technician. Whether it's your furnace that needs a repair or another issue, a technician will be able to lead you in the right direction and assist you with solving the issue. For more information, contact your local furnace repairs service.
