Different Temperatures In Some Rooms

This is usually just a matter of balancing, or adjusting the airflow to each room so they will even out. Or sometimes making the rooms you want comfortable and unused rooms less so. If a room is heating or cooling quicker than other rooms, the airflow can be lowered to that room to even things out, also sending more air to other areas. Usually it's best to start in the room with the thermostat in it. This will allow your system to run long enough to satisfy the harder to condition rooms. If some rooms can't keep up with others and the airflow isn't as noticeable, make sure the vents are fully opened. Many systems have dampers installed on the individual supply runs coming off the main supply trunk. This is either in the basement or attic. They are identified by little metal handles which open, close and adjust a metal damper. By dampening the airflow here to rooms with more air, it will send more air to the rooms that need it. If your system doesn't have dampers or if they are inaccessible, then dampening and balancing will have to be done at the supply registers themselves. Just adjust as necessary. In most homes, there is always one or two rooms that just can't keep up with the others. Maybe it has the longest duct run with the most elbows and turns, or it is over a garage with more heat loss or isn't insulated as well. Whatever the case, balancing should help. Here are a few things to check. * Open return vents, if your home has high and low ** The top should be open in summer ** The bottom should be open in winter * Check for proper insulation * Check dampers-Are they open? * Check windows-Drafts on windy days? * Try turning the fan on continuously to help spread out the heat * Dirty filter - the cleaner the filter the better the airflow * Close shades and/or curtains
