We all know that heat rises, and that’s a common household HVAC problem. Take a look at some of the major factors that can contribute to this issue:

Air Conditioner

Replacing the air conditioner is a large expense, but it’s also a part of owning a home. The average lifespan of an air conditioning unit is 15 years, and with every year it’s used, the system loses efficiency. If the air conditioner is primed for replacement and you’re hot in the second story, it could be that the system just can’t keep up with demand anymore. 


The farther the air conditioner is from the second floor, the more ductwork it has to pass through to get there. And if the ducts have leaks, a lot of that cold air can get lost before it reaches the upstairs rooms. Joints in ductwork shouldn’t only be bolted together, but also be sealed with mastic to ensure that air does not leak. For full efficiency, ducts should also be insulated.


Insulation in the attic is an important barrier all year. It keeps hot air during the winter and out during the summer. If you can see the joists on the floor, you should add more insulation on top of what you already have. 


This isn’t a factor with all homes, but if the multi-story home is surrounded by trees, you could be getting lots of shade on the ground floor and lots of direct sunlight coming in upstairs. While you wait for the trees to mature, consider upgrading the windows upstairs and keeping them closed. Shades, curtains, and drapes can make a huge difference in blocking out daytime heat.

Figuring out which one of these factors is affecting the comfort — or whether it’s a combination of factors — is easier said than done. If you need help finding the answer and fixing the problem, contact us today.
