Air flow is one of the most important parts of an HVAC system functioning properly. All that precious, conditioned air needs to flow throughout the house in order for you to get the benefit of it, now isn’t that right? It’s a simple concept and quite easy to understand. You get it, right? Yet, you may have forgotten about that vent or air supply grill that is being all but blocked by the living room couch. Sometimes, it’s easy to not realize when you’re restricting air flow throughout your home. Every now and then it’s a good idea to scour your house to make sure that vents, intakes, and air supply grills are completely clear of all obstructions. Once that is taken care of, inspect them to see whether or not they are dirty. You can use a duster and or a vacuum cleaner with a hose attachment to get really thorough with the cleaning process. Now you should have unobstructed air flow throughout your home and that’s a good thing because it prevents problems with energy efficiency. “What if I don’t want to cool a room?” you may ask. Well, the last thing you want to do is close the air supply grill for that room. You might be tempted to think that doing so will help you save money, because you will be cooling one less room, but air conditioners don’t work that way. In fact, closing that supply grill can cause problems with your unit, and ultimately lead to damage! Remember, keep your supply grills free of obstructions, clean them, and leave them open.
