  • We are having trouble getting cool air upstairs in our two story home, what can I do to make the upstairs more comfortable?
    A comfortable main floor and a warm second floor is a common complaint with central air conditioning systems. This temperature variation is caused by the fact that cool air is heavy. Heavy air requires more effort to move, especially upwards. Your furnace fan has to work much harder to get the air up two stories. Additionally, cool air, unlike warm air, tends to fall, so that once you actually manage to get the air upstairs, it will naturally fall back to the first floor. Don’t despair, there are some things that you can do. Make sure your furnace fan is on the highest possible setting. Most furnaces installed today will have a multi-speed, direct drive fan motor. Have your service contractor check to make sure that the highest speed is being used for air conditioning. If your fan motor has belts and pulleys, check with your contractor about installing a larger pulley. Adjust the balancing on your ductwork to force as much cool air upstairs as possible. If your ductwork is accessible from your basement, and has dampers installed in each of the supply air runs, make sure the dampers for the upper floor are fully open. You can also close any dampers for rooms on the first floor that do not get much use, or are very small. Some examples may be a powder room, formal living or dining room. You should keep the dampers fully open for the kitchen and the main living or family area. If the ductwork is not accessible, or doesn’t have any dampers, don’t despair. You can balance the air flow by opening and closing the dampers in the supply air registers. If you cannot get a register closed, we have been told that covering the register with a telephone book works well. Don’t forget to re-balance the ductwork system when you switch over to heating. During the heating system you want most of the warm air delivered to the first floor, it will rise on its own to the second floor. Use fans to help move cooler air. Placing a large fan at the top of the stairway can help to draw the cooler air up. A ceiling fan installed on the second floor can also be a big improvement. Check the return air grills. Make sure they are clean. Consider installing “High Wall” return air grills on the second floor. High wall return air grills are installed near the ceiling, not near the floor. This enables the furnace to draw the warmest air from the top of the house back into the system. Your service contractor can give you more information and let you know if it is possible to install high wall grills on your system.
