In high school we all learned about physics. One of the many things we learned was that hot air always rises and cold air always falls. For example the basement is always cooler than the rest of the house in the summer. It becomes the retreat on hot summer days if you have no A/C. Another example is if you live in a 2 story house and you find that your upper level is always hotter than the main floor. This is all because of physics.
There are somethings that can help:
1 Ensure that you have the correct size for your HVAC system. This will ensure that the amount of air coming out of your system is able to reach even the farthest corners of your space.
2 Make sure you have the correct size of ductwork for your home so that air can move easily through the ducts and vents. Also if your ductwork is too smal you will find that it is noisy.
3 Keep vents, air intakes and the entire HVAC system clear and free from blocks that could impede proper air flow.
4 Ensure that you have proper ventilation and insulation in your attic/roof top. An improperly set up attic can reach 140 degree F which will make your upper level very hot and uncomfortable.
