There are a few possible causes for this problem. It could be a dirty filter. It could also be closed or partially closed vents or dampers, or an obstruction in the ductwork. There may also be a problem with the blower motor. 

Check the filter first. If the problem is not with the filter, it may be a good idea to contact a heating professional to troubleshoot your furnace. If you'd like to have a contractor take a look at this, we can help you find one, here

In the summer ( in Oklahoma) I have found I can set the thermostat on 78 and be comfortable if the air movement is high enough. One time I had a technician adjust the American Standard Freedom 90 to its highest speed. I remained comfortable all summer, but when winter came and the heat would come on , it became too hot. Another tech adjusted the furnace to run on winter schedule. Since then I have had a number of techs try to reset the unit so I could have the high speed when I want it, none have figured out how to do it. I started the system of high speed air and higher thermostat a number of years ago, in one house (3000 sq.ft.) I cut my electric bill by 1/3. I seldom hear any company or group advocating this set up, I wonder why? I now have a 2 stage furnace which was installed in September of 2001, the 2nd stage has never come on during all those years, my house is well insulated so spending money for a 2 stage was a waste. I would like to have a furnace that has a switch so I can select the speed I want and not have a tech come charge me for something he knows nothing about. I would appreciate any information about a furnace which would handle the problem, or information as to how I can my unit customized with a speed selector switch.
