Why is My Room So Hot?: How to Fix Hotspots in Your House

“Why is my room so hot?”

Our HVAC technicians at Santa Fe Air get that question a lot. 

You want your room to be warm in the winter, but uncomfortably hot? No thanks. There’s nothing worse than tossing and turning through the night because you’re drenched in sweat, and a fan just blows the hot air around. 

The best way to find the answer is to figure out the source of the problem. Based on what we’ve seen, here are common causes for those annoying hotspots and solutions to fix them. 

Problem #1: You don’t have insulation

Proper insulation ensures that air stays at the right temperature as it runs through the ducts. The problem can go both ways, but this issue tends to be more noticeable in the summer. Say you have areas that don’t receive A/C such as an attic. Without insulation, when cool air runs through the ducts in those areas, it’ll heat up. As a result, the air that comes to your room ends up being warmer than it should be. 

How to fix improper insulation: Simple. Go back through your ducts and add insulation. If you’re unsure how to do it, an HVAC technician can help you. 

Problem #2: Your room is upstairs

It’s common for two-story or multi-story homes to have excess heat on the upper floors. This isn’t an HVAC problem; it’s simply because heat rises. In some instances, it can be manageable with fans, but in other cases, the excess heat is just too uncomfortable. 

How to fix upper level heating: One of the best solutions to fix upper level heating is to install an HVAC zoning system. A zoning system separates areas of your home and allows you to control the temperature in each zone. That way you can create a zone for your downstairs and another for the upstairs.

Problem #3: You don’t have the right size HVAC system

Your furnace and A/C unit should fit the size of your home. If they are too big or too small, your heating and cooling will be out of whack. For instance, if your furnace is too big, it’s going to blast too much heat, leaving you sweating in the middle of January. 

How to fix the wrong sized HVAC system: You could try temporary solutions like fans, but in the long run, the best thing to do is to get the right-sized system. And before you groan about the price, trust us, it’s going to save you in the long run. 

Problem #4: You renovated or have a new addition

Removing or adding walls changes the way air flows through your home, which can throw off how your room is heated. Plus, adding square footage forces your HVAC system to circulate air in more places than it had to before. 

How to fix circulation in new spaces: Again, zoning can do wonders for new additions or renovated homes. If that’s not an option, you can add a second HVAC system, especially if you’ve added a large amount of square footage.
