To increase HVAC airflow, check for debris in air ducts and functioning vents, ensure compressor generates enough pressure, and repair leaks or tears. Regular maintenance checks are necessary. Poor ventilation can also affect airflow. Clogged compressor can be caused by a clogged filter or damaged intake valve. If the air handler system is too small, replacement may be necessary.
There are several ways to increase the overall heating, ventilation, and air conditioning (HVAC) airflow within facilities, and many of them can be implemented without great expense to the consumer. Ensuring that the air ducts are free of debris and that the vents are functioning properly is normally the first place to check, followed by making sure that the compressor is generating sufficient pressure. Another common HVAC airflow problem is leaks or tears within the air ducts, and a quick repair will usually fix this problem. If none of these appear to be the case, it’s possible that the actual compressor or cooling unit is too small for the home it’s installed in, then replacement may be the best option.
It’s common for numerous problems to appear inside your HVAC ducts over a long period of time, and because it’s nearly impossible to prevent, regular maintenance checks are necessary. One of the major problems consumers face with HVAC airflow is tears within the ductwork itself, which could be caused by anything from a protruding nail to a small animal that has gained access to the crawl space. If the damage is minor, duct tape can be applied over the torn areas to create a new seal, allowing the pressure to return to normal. Sometimes larger repair projects can be resolved by implementing a patch, while complex rips may require replacement of the pipeline itself.
Poor ventilation can also negatively affect HVAC airflow, and if the ductwork is solid, the problem may lie within the vents themselves. A common tactic is to close all unused vents to determine if pressure builds within other areas of the structure, and if not, there is likely to be some type of blockage in the vent itself or directly below it. The easiest way to correct this problem is to physically remove each of the vent covers and vacuum out any debris or dust contained underneath them, although more serious problems may require professional repair.
If the problem is a clogged compressor, there can be many causes. A clogged filter or damaged intake valve can reduce the amount of air drawn into the unit, and these areas should be inspected frequently for cleaning and maintenance. Eventually, the lack of air will cause the compressor to freeze so that no air can enter the device, and prolonged use in this state can permanently damage the motor inside. If the compressor is getting adequate air intake and the HVAC airflow is still minimal, it is possible that the air handler system is simply too small to cool the entire facility.
