We also sell Heat-Recovery Ventilators (HRV) which bring fresh air in while exhausting indoor air after most of the heat is removed from it.
Every home must “breathe” in order to maintain indoor air-quality. You may feel some air seeping into your home around windows, doors, skylights, electrical outlets, walls, floors or the roof. This is air infiltration and every home has some air infiltration. Air Infiltration creates air changes (outside air replacing inside air).
Home built in 1980 had an average of up to 15 Air Changes per Hour (ACH). In a newly built home, the maximum allowed Air Changes per Hour is up to 5 (in DFW). An Energy Star Certified home, the maximum allowed Air Changes per Hour is up to 3 ACH (in DFW).
While most older homes leak enough air to satisfy their air-quality needs. Newer homes are built to high energy-savings standards, and some do not leak enough air. These homes must have a ventilating device to ensure indoor air quality.

It uses that recovered heat / cooled temperature to heat or cool incoming fresh air before it enters the home.
This diagram shows how the HRV works: 1. Removes stale air 2. Removes most of the heat or cool temperature from the stale air 3. Uses that recovered heat / cool temperature to bring the outdoor air temp close to the indoor air temp. 4. Sends the fresh air into the home.[/fusion_text][/one_half][one_half last=”yes” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” hover_type=”none” link=”” border_position=”all” border_size=”0px” border_color=”” border_style=”solid” padding=”” margin_top=”” margin_bottom=”10px” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ animation_offset=”” class=”” id=””][imageframe lightbox=”no” gallery_id=”” lightbox_image=”” style_type=”none” hover_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”center” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ animation_offset=”” hide_on_mobile=”no” class=”” id=””]

The most common way is the “blower door test”.
The technician seals off an open door with a temporary vinyl seal which has a blower in the bottom. The blower is powered through a system which increases the outward air-flow as required. The purpose of this test is to create negative pressure inside the house which will then identify everywhere the house leaks air. Once identified, many of these leaks can be sealed.
Some things cannot be corrected, as the design of the building component must allow air to infiltrate. This is common of windows which slide up & down or sideways. To make them as air tight as possible, they would become very difficult to open and close. The design of the window requires a balance of air infiltration with ease of operation.[/fusion_text][/two_third][one_third last=”yes” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” hover_type=”none” link=”” border_position=”all” border_size=”0px” border_color=”” border_style=”” padding=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”” animation_speed=”0.1″ animation_offset=”” class=”” id=””][imageframe lightbox=”no” gallery_id=”” lightbox_image=”” style_type=”none” hover_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”none” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ animation_offset=”” hide_on_mobile=”no” class=”” id=””]
