Whether you have your heating or air conditioning system running (at this time of the year, you never know which one you’ll need) a common trouble you may encounter is a drop in the airflow coming from the room vents. There are many different reasons for a decline in airflow, which is why we recommend you call on our professionals to take a look into the situation to discover what needs to be fixed—or replaced.
Below we’ll look at some of the causes of low airflow and how they can be remedied.
Clogged air filters
The first investigation to make is one that doesn’t require professional assistance: check on the air filter for your HVAC system. The filter is usually located at the point on the HVAC cabinet where the return air duct connects to the air handler. Slide the filter from its slot to see if it’s heavily clogged. Change it for a new one if it is.
Air leaks in the ducts
The trouble may not lie inside the heating or air conditioning system, but in the ducts connected to them. The ductwork needs to maintain an airtight seal along its length to retain air pressure. Even small leaks can cause a significant air pressure drop, and a resulting plunge in airflow. You can’t seal up the duct leaks yourself with store bought duct tape. Even locating the leaks in the first place is difficult. Our experts can take care of sealing the ducts, or replacing them with new ductwork. (We fabricate sheet metal to custom fit your home and allow for the best airflow.)
Blower fan and motor troubles
The blower fan in the air handler is responsible for the airflow through the ductwork. If the fan or its motor is dirty or damaged, it will start to affect airflow. Sometimes the repair job is as simple as cleaning the components. Other times the motor will need to be replaced.
Failing air conditioner or heater
There are times when the decline in airflow is part of the inevitable decline of the HVAC system itself. Maintenance and repairs can only keep a heating or air conditioning system running for so long. Eventually, the best choice is to have a new system put in. Furnaces can last from 15 to 20 years, and air conditioners from 10 to 15 years. If your system is reaching the outer limits of its estimated lifespan and is no longer under warranty, it should probably be replaced.
If a system replacement is the best way forward for you—make sure you consult with professionals first before you make a choice—then spring is a great time to have it done.
