Air Ventilation in Your Home

Thursday, May 1st, 2014

Often times if our homes aren’t being properly heated and cooled, we assume the issue lies with the furnace or air conditioner. This is a good place to start and by no means should it be neglected, however your home’s ductwork and ventilation system plays an important role in keeping your home at a desired, comfortable temperature.

A professional HVAC technicican should be the one to properly asses your home’s ductwork. Based on the overall square footage of your home, square footage of each individual room, and the insulation of each room, there are specific requirements for the size of the duct leading to the room, and the dimensions of the register that acts as a gateway for air to be dispersed throughout the room. If the size of the duct and register are either too large or too small, the wrong amount of air will be delivered to that room. For example, a bathroom and a bedroom should not have the same capacity ventilation network distributing air to each room, and if that is the case, the bathroom ductwork and register should be reduced in accordance with the room’s size so the bedroom is not being forfeited the proper amount of air.

Common Sources of Low Air Flow

* Blockage and build ups. Dirt and dust can build up on your air filter, as well as clogging tight lines and even wider spots like your ducts. The net result – besides spreading dust and dirt throughout your home – is to lower the overall flow of air, forcing your air conditioner to work harder to do its job and increasing the risk of future repairs.

* Fan motor problems. Faulty electrical wiring or an internal problem with the fan motor will cause it to turn more slowly, lowering the flow of the air. In the case of a damaged wire, the problem is easy for a professional to correct, but a burnt-out motor is a serious repair that may necessitate replacing the whole air conditioner.

* Bent or misaligned fan blades. Fan blades can become misaligned through damage, or individual blades may become bent. The fan may also run into trouble if a foreign objects like a twig or loose screw gets jammed into its mechanism.

When your ductwork is inspected by a professional, they will also check to see if any areas have begun to sag and if they are in need of a cleaning. When ductwork sags, it becomes susceptible to joints opening and leaking air into the dead spaces of your home. If this is the case, then you are paying for air that isn’t being delivered to your living space, and your HVAC unit is working harder than it should be to maintain an appropriate temperature. Over time, dust and debris will collect in your ducts, compromising the quality of the air you’re breathing. You ducts should be cleaned regularly, with the frequency depending on the factors within your home, like number of occupants and pets and allergy concerns.
