Why Your Furnace Output Is Low?

• Clogged Air Filter: If your furnace seems to be having trouble circulating much air at all, it might be due to a clogged air filter. The air filter is designed to protect the furnace from the dust and other particulate contaminants that are commonly found in the ducts of the home. While it does a good job at protecting the system, it can’t get rid of the contaminants that it collects. If the filter isn’t changed every three months or so, it will become clogged. This cuts off the majority of the air in the ducts from entering the furnace. No air into the furnace causes quite a few problems, including a drop in output. The good news is that changing the air filter should resolve this problem immediately.
• Short Cycling: Short cycling is what happens when your furnace turns itself on and off every couple of minutes. It’s extremely bad for the furnace, for a number of reasons. It cuts into the output for the furnace, since it doesn’t have the chance to complete a full heating cycle. However, the negative effects extend far beyond just lowering the output. The strain of constantly stopping the cycle before it can complete causes the wear and tear on the system to increase significantly. A furnace that is allowed to short cycle for an extended period of time will break down more often, and have its lifespan shortened by a number of years. Short cycling is typically the result of electrical issues, and you will definitely need a professional to fix it for you.
• Air Handler Issues: The air handler is the part of the furnace that actually circulates air throughout the house during operation. It’s basically a large motor with a fan attached to it. The air handler motor can last for a very long time, but it will wear down eventually. If the motor starts to get towards the end of its useful lifespan, it will often start to generate a loud grinding sound while the furnace is operating. If you hear that sound, it’s a very good idea to call for repairs as soon as possible. If you’re lucky, it’s just the bearings that will need to be replaced. Otherwise, the entire air handler motor might need to be replaced, which is much more expensive.
