Are dirty vents costing you money?


Even though the weather is just starting to get warm, it’s never too early to make sure your central air conditioning is running at peak efficiency. The middle of a heat wave is not the time for discovering a problem with your vents.

One of the most common problems found in HVAC systems is obstructions in the ductwork. If a duct is blocked, some rooms won’t heat or cool the way they’re supposed to. Because the rooms can’t reach the temperature you’ve set on your thermostat, your HVAC system will be working constantly to keep up.  This can cause temperature fluctuations between rooms, poor air quality and an increase in your energy bill.

Here are some of the usual causes of an obstructed HVAC system:

Blocked Vents

Dust and dirt can clog vents blocking the flow of air into the room. Make sure your vents are clean both inside and out. Clear out any debris regularly. If dust is constantly accumulating from the inside it might be time for an air duct cleaning.


Dirty Air Filters

Air filters should be changed regularly in order to maintain energy efficiency and good indoor air quality. If your air filters are dirty and clogged, they can impede airflow and reduce the air quality in your home. If you find yourself sneezing a lot inside, check your air filter.


Closed Zone Dampers

HVAC systems utilize dampers in the ductwork to control the way air flows in your home. Make sure all of the dampers in your home are completely open. Sometimes dampers can get stuck closed or can become loose and close on their own. This will completely obstruct the air in that particular duct and could affect the airflow in your entire house. If all of them are open and you’re still not feeling any air coming through, you may have another obstruction farther in the duct.


Physical Obstructions in the Ducts

Another common source of ductwork obstructions are physical objects inside your ducts. Dust, dirt, pieces of old air filters, and ductwork insulation that has come off are especially common culprits. You may also find debris from construction or remodeling projects, such as wood chips or insulation. Vermin or insects may find their way into your ducts and leave behind debris. You should get an air duct cleaning any time you need to hire an exterminator to clean up what was left behind.
