Troubleshooting Low HVAC Air Flow
Your HVAC system's airflow is essential to providing climate control throughout your house since air is the primary method of transportation for both heating and cooling throughout the year. There are a number of reasons why your system's airflow could be impeded, each of which can cause your utility bills to skyrocket while your HVAC system's efficiency plummets. Understanding some of the more common reasons why your HVAC system may not be able to properly transport air around your home can help you identify and fix issues early, before they are able to grow worse and more expensive.
Dirty Air Filters
The primary reason why your HVAC system may not be able to properly pump air throughout your home is that the air filter is clogged with dust and other debris. This normally happens over time as your HVAC system sucks in air, and it can be easy to forget to replace the air filter over time. Generally, you'll want to replace your filter at least once a year, but more often if your system sees a great deal of use. Filters can usually be replaced by hand or with a screwdriver.
Blocked or Damaged Ducts
Over time, the same debris that can clog your air filter can create blockages within your ductwork, preventing proper airflow and causing your air conditioner to operate for longer periods of time to provide the same amount of climate control. Alternatively, age can also damage the seal and insulation around your ducts, which means that chilled or heated air is able to leak out or loses its temperature as it is transported, reducing the overall effectiveness of your HVAC system. A contractor will have to do a duct inspection to determine whether you can clean your ducts or have to have them repaired.
Clogged Condenser and Return Vents
Your furnace has a return vent on its side, which acts as the air intake for the entire system. Your air conditioner has a condenser, which is an entire unit located on the exterior of your home that performs the same function. Debris, dust, and other objects can form blockages in your return vent or condenser, reducing the ability of your system to function by impeding general airflow. Thankfully, you can unblock both of these by simply dusting and removing leaves, branches, and other obstacles by hand, ensuring that your system has a clear intake path.
