Tips For Mechanical Air Filters to Improve Home Energy Efficiency
Reviewed and Revised on 10/30/2013
- Studies have shown that dirty filters on the return air grille of your heating and cooling systems greatly reduce the efficiency of your system, wasting energy as well your money. Dirty filters can also reduce living comfort by restricting air circulation and not capturing dust particles, allergens and pollutants in the indoor air. Your equipment may have to work harder and its life can get shortened. It is

Reasons for Home Ventilation
In days past, energy was cheap and energy efficiency was not a concern. As energy prices increased, homeowners sought to reduce costs by insulating attics, walls, and basements, which reduced large-scale heat transfer and energy loss. Recently, due to high energy costs, better materials, and better information, homeowners and builders are reducing the air leaks to reduce energy loss and and costs. In some homes, the home natural air exchange…
Understanding Air Flow in Homes for Energy Efficiency
Reviewed and Revised on 11/12/2013
Air tries to equalize between higher and lower air pressure areas. If there is a pathway (a gap) and a pressure difference, it will move through that pathway whether we want it or not.
To be an effective air barrier or air flow retarder, a material must not only block airflow through it, it must also be installed in a way that eliminates even small gaps, be continuous all around the conditional space and …

The benefits of installing a heat exchanger in a home include improved moisture removal, decrease in the potential of structural damage, elimination of harmful pollutants, and reduced energy costs. The resulting improved indoor air quality can affect the home occupants and their health in a positive manner. Installation also increases the resale value of the home.
A simple payback calculation, where the energy savings pay for the purchase and installation of a heat exchanger …
Choosing an Air-to-Air Exchanger System
One way to minimize air quality and moisture problems in a home, without opening a window, is by the installation of a mechanical ventilation system such as an air-to-air heat exchanger. An air-to-air heat exchanger brings two air streams of different temperatures into thermal contact, transferring heat from the exhausting inside air to incoming outside air during the heating season.
In summer, the heat exchanger can cool and in some cases, dehumidify the hot outside air passing through it and …
