Why is one of the rooms in my house warmer than the others?

Your system is designed to maintain reasonably consistently temperatures. With “Normal Room Occupancy”, your system should maintain temperatures within 3 degrees of the thermostat setting when measured in the middle of each room. There may, however, be differences from room to room based upon a number of factors. These factors include:

    • Single system 2 story homes and townhomes homeowners will typically find that their upper floor is warmer than the first floor due to the fact that heat rises. This is normal.
    • Rooms having greater exposure to the sun at different times of the day may experience some temperature differential as well. Rooms in the East will typically be warmer in the morning and Western exposure rooms may be significantly warmer in the afternoon.
    • Your new home system was designed for “Normal Occupancy.” This means if you plan on converting a spare room into a home office, please discuss it with your builder and have them let Air Flow Designs know before the installation of the duct work and equipment. Otherwise, multiple computers, printers, copiers, fax machines will all contribute significant latent heat to the room and you may be unable to keep the room at a comfortable operating temperature.
    • A room without any type of window covering (Blinds, Shutters, Draperies, Shades, Curtains) allows greater solar heat infiltration and will be warmer than it was designed to be.
