During our hot, humid Connecticut summers it's common for homeowners tell us that the upper levels of their home feel hot and stuffy, while the lower levels are freezing cold. In multi-level homes there can be as much as a 8-10 degree difference between the lowest level and the highest level in the home. Here are some steps you can take to even out the temperatures.
First, it's important to leave all of the air ducts open throughout the house. Central heating and cooling systems are designed to work with the air volume of every room. Closing air ducts can reduce the performance of the system and waste energy.
Leaky Air Ducts
Even minor leaks from poorly aligned or uninsulated ducts can dramatically reduce airflow, making it difficult for conditioned air to reach the outer reaches of the home. An HVAC professional can help find and seal leaks with with special pressurizing equipment.
Check Insulation Levels
Improving attic insulation can mitigate air leaks and can reduce the effect of environmental factors on the temperature inside of the home. The US Department of Energy has some great tips for installing insulation here
Consider a Zoning System
A zoning system allows you to control the temperature on multiple levels of the home independently using thermostats installed on each floor. The thermostats are rigged to control panels that adjust dampers installed inside your ductwork.
In addition to balancing the temperature on different floors, a zoned system will allow you to heat or cool individual rooms on demand, or close off unused rooms entirely.
