Replacing the filter in your Bryant furnace is a simple, do-it-yourself job. To replace a filter you just need to take out the old one and slide in the new one. Make sure that the airflow arrow is pointing toward the blower motor or furnace. The location of the filter depends upon what model Bryant furnace you have. Usually the furnace filter is inside the blower compartment. Check the manual that came with your filter, or consult with a parts supplier to make sure you buy the right type of filter for your furnace.
Turn off the power at the main circuit breaker. Locate the blower compartment next to the cold air return. To access the blower compartment you have to first remove the top door and then remove the bottom door.
Open the bottom door to access the lower blower compartment inside. Inside the bottom door you will find the up-flow filter, for air moving upward. Remove the old filter and slide the new one in.
Open the top door to access the upper blower compartment inside. Inside the top door you will find the down flow filter, for air moving in a downward direction. If your furnace takes only one filter, remove the old filter and slide the new one in. Many systems take two filters, so you will find a V shape filter system. Slide out the old filters, and insert the new filters upward into the V-shaped holder.
When you put the top and bottom doors back in, make sure that you place them over the frame of the furnace so that they interlock with the safety switch. The furnace will not work if the top and bottom doors don't engage the safety switch.
