Furnace Not Blowing Enough Air: Troubleshooting This Common Problem
Is your furnace running, but not producing enough hot air to keep your home at a comfortable temperature? If so, you may be able to correct this common problem without the need to call in a professional repairman. In order to complete this task, simply follow the steps outlined below.
Step 1: Ensure The Furnace Is Taking In Enough Air
Your furnace will only be able to put out as much air as it is able to take in. Therefore, anything that blocks the flow of air to your furnace could be to blame for your current heating problems.
Begin by finding your main intake vent. If you are not familiar with the location of this vent, look for a vent that is larger in size than the other vents in the house. This vent will typically be located somewhere near your thermostat.
First, ensure that there is nothing blocking the vent from the outside. If you have recently moved furniture around, you may have accidentally blocked off this vent. Simply moving the furniture a few feet away from the vent will ensure that an adequate amount of air is able to be pulled in.
If there is nothing in front of your air vent, the problem may be inside the vent itself. Open the vent by turning the thumbscrews or other fasteners a quarter turn. Once the vent cover is open, check the air intake filter to ensure it is not clogged with dirt and debris. If this filter is dirty, it will need to be cleaned or replaced.
After checking to ensure nothing is blocking air from getting to your furnace, simply turn the furnace on and wait a few minutes to see if your output levels improve. If you are still not getting enough hot air, simply move on to the next step.
Step 2: Ensure All Of Your Air Ducts Are Connected Tightly
Over time, it is possible for the connectors that are used to secure your air ducts to come loose. When this happens, the air that your furnace produces will be allowed to leak out long before it gets to your vents. A good indication that this is the issue behind your heating problems is that the issue will only impact select vents in the house rather than affecting the entire system.
In order to determine whether or not a loose or disconnected duct is to blame for your furnace's low output, you will need to begin by checking all of the duct connections surrounding your furnace. Run your hands around the connections slowly to feel for any air leaks. If no leaks are detected, move on to the ducts in your attic or crawlspace.
If you are still unable to find the source of your low pressure problems, you will need to contact a qualified contractor to investigate furnace repairs in the presence of a more serious problem with your heating system
