IAQ - Indoor Air Quality

Humidity / Airflow / Filtration / Carbon Monoxide / Volatile Organic Compounds / Moisture / Fresh-Air Ventilation / Temperature

Why should you keep your home’s air clean?
Poor air quality can lead to poor health. Pollutants in your home’s air can cause dizziness, headaches, nasal congestion and fatigue, plus it can aggravate allergies / asthma.

What causes indoor air problems?
Pollutants can come from many different sources inside the home. For instance carpeting, upholstery, cleaning chemicals, and plastics release chemicals into the air call volatile organic compounds. High temperature and humidity increase concentrations of mold and bacteria. Leakage or negative pressurized homes pull dust, dirt, and pollens into the home. Cooking orders, pet dander, dust mites, viruses, and fungi are constantly present in all home as a normal part of life.

The average home should have at least .35 ACH (air changes per hour). An ACH of 1.0 means that air in the home is changed once per hour. Newer, high-efficiency homes generally have an ACH rating of less than .35, and many are as low as .05. That can lead to extremely poor indoor air quality. The Lennox heat recovery ventilator (HRV) provides a simple and economical way to freshen the air. Thanks to some clever engineering, the Lennox HRV is able to conserve energy from indoor conditioned air and transfer it to the outdoor air as it's brought into your home.

"Most people spend over 90% of their time indoors, not knowing that the air they are breathing may be more polluted than the air outside. The Environmental Protection Agency has reported that indoor air pollution levels can be 100 times higher than the air outdoors. Even in the cleanest homes, the air you breath can be littered with dust, pollen and other harmful contaminants. A cubic foot of air can have as many as 30 million pollutants, (particles so small, they are invisible). And, in this case, it's what you can't see that can hurt you. Breathing contaminated air puts the health of you and your family at risk. In fact, the American College of Allergists says that 50% of illnesses are caused or aggravated by polluted indoor air."

Fuel burning appliances in your home need a reliable supply of outside air to work properly. This replacement air is commonly called "combustion air". Without enough combustion air your house can quickly become polluted with unhealthy gases. In general, combustion problems such as back-drafting of gasses occur when fuel-burning appliances demand more air than the house can supply through normal air leakage. you can easily check for combustion air by performing a simple draft hood test. The draft hood is an opening in the vent pipe just above the water heater or furnace flu. The test is done by holding a smoking object (incense stick) near the hood when the appliance is running; and watching to see if the smoke is drawn up the flue. If the smoke is blown away from the hood, combustion gases are not going up the flue, as they should. The Minnesota building code requires that all new homes being built or when revisions are made to fuel burning appliances in your home, that a combustion air duct that brings outside air directly to the heating system be installed.
