Restrict air flow could be why room not getting heat?

Air flow is an essential aspect of your home’s HVAC system. It is what makes your home comfortable to live in by ensuring proper temperature control and air quality. However, if your home’s air flow is restricted, you may be dealing with several issues, including rooms not getting enough air. In this blog post, we’ll look at some of the reasons why your house may not be getting the proper air flow and how Vacu-Man can help with cleaning your furnace and air duct systems.

One of the main reasons for restricted air flow is the number of bends in the air duct system. For every bend in the air ducts, up to 7 ft.² of air flow can be lost. If you have more than three bends in your air duct system, you may be losing up to 21 ft.² of air space. This is a significant amount of air, and it can cause rooms on the far end of the system to get little or no air flow.

Another reason for restricted air flow is the location of your furnace. Ideally, your furnace should be situated in the center of your home. If your home is larger than 3000 ft.², you may want to consider getting a second furnace. Additionally, a damper in the basement that is closed could also be restricting air flow to the far end of your home.


Restricted air flow is one of the most common problems associated with air ducts that are too small. If there is not enough room for air to move through the system, it can result in poor circulation, leading to an uncomfortable and inefficient home environment. The use of flex piping as opposed to rigid ductwork can cause even more compression and hindrance to ventilation, making the proper size selection all the more important when considering an air duct installation. The right selection ensures better efficiency and cost-effectiveness of running any ventilation systems.\


A blocked air filter or evaporator coil in the furnace can also restrict air flow within the home. If there is anything blocking the air flow within the furnace, it may not allow the air to get up into the home.


Debris, items stuck in the air vent system, or even a critter or animal that has found its way into the air duct system could also be the reason for restricted airf low. Construction or renovations that lead to debris such as lumber, drywall pieces, or even dirt getting swept into the air ducts can also restrict air flow.


One solution to improve air flow is to block off the register in a bathroom that is not being used regularly. This will force the air into other areas of the home. However, it’s essential to ensure that the cold air return is not blocked, as you need as much air flow as possible coming back to the furnace.
