Updating Your HVAC Unit

Three Items To Check If Your HVAC System Is Having Airflow Problems

During these last hot days of summer, you will want to make sure your HVAC system is working as energy efficient as it can. One of the first signs of a problem may be when your airflow does not seem as strong as it has been in the past. There are three common causes for this problem, and you need to check all of these prior to calling your HVAC professional.

When Was The Last Time You Changed Your Filter?

When you regularly replace your air filter, you do the following:

  • Extend the life of your HVAC unit by keeping dirt out of it.
  • Reduce your energy costs by keeping your system from having to work harder.
  • Keep the air quality healthy in your home.

When your air filter is clogged, your system is not able to pull adequate amounts of air in, and therefore cannot put air out. If you are like most people, you understand the importance of changing your air filter, but you simply forget to do it. Most HVAC systems recommend you check and change your filter monthly. This is a very inexpensive part of your home maintenance you cannot afford to overlook.

Do Your Air Registers Need Opening, Unblocking, Or Cleaning?

Your HVAC has supply air and return registers throughout your home. Depending on your system, these may be located in your floor or ceiling. Due to the fact the ones on the floor are often located around the edges of the room, it is easy to block these with furnishings or drapery. 

Check to ensure you have not accidentally blocked or closed these registers. If they are all open, make sure they are clean. You may be surprised at how much trash can fall into registers which are located on the floor. To help make your HVAC system more efficient, unfasten the faceplates on your registers and use your vacuum hose to clean them out. 

Have You Accidentally Closed Off Your Dampers?

Many times, people will close off the dampers to their HVAC system to block the air flow to unused rooms. Not only will this help to save money, but it will often increase the amount of air flow available to other areas of your home. 

Make sure all of your dampers are open. Depending on where your dampers are located, you may have to get a professional to do this for you. If these efforts fail to restore your airflow, call a professional HVAC technician to check the other components of your system.
