Home Ventilation

|
Most of our modern homes have fairly good exhaust systems. We have exhausts in the kitchen, the bathrooms, and often even the laundry. Yet when air from a home is only exhausted, the home is depressurized. This causes the house to suck for air which, in turn, pulls uncontrolled and unfiltered air from the attic, the attached garage, and the outdoors. When air is pulled in from the attic, it carries heat/cold, insulation particles, dust, and even rodent droppings and bug parts with it. When air is pulled in from the garage, it carries heat/cold, automobile exhaust, and fumes from anything stored in the garage from gasoline to fertilizers to paints. When air is pulled in from the outdoors, it carries heat/cold, pollen and other allergens, and all the chemicals and general pollution that is in our North Texas air. No wonder experts say the air quality inside our home is often worse than the outdoor air quality. A balanced ventilation system is the answer The system is balanced when fresh air is supplied to the home in about the same ratio as air is removed from the home and the fresh air is first filtered. The system might even use a heat recovery ventilator, although that is more common and more cost effective in the north than in Texas.. Balanced ventilation is the most reliable and effective type of system for our homes. Unfortunately, it is also the most expensive to install, particularly in a retrofit. The central ventilator is expensive because it has two fans and may have a heat exchanger. A good system may also use separate ducting for both the exhaust air and the supply air, another expense. Yet much can be done without installing a balanced system. A skilled consultant will survey your home and suggest ways to stop uncontrolled air from entering it and/or help you eliminate many of the problems the exhaust systems trigger. |
