Home Ventilation, IMPORTANT? …Or no never mind.
This is the first of a series of articles that will deal with the home, and the ventilation it needs.Home ventilation involves not only expelling old stale air, but also allowing fresh air to enter the home. It’s all about balance- and its adequacy goes largely unnoticed. The methods needed to obtain adequate ventilation depend on the home itself. Older homes can provide adequate ventilation using exhaust only fans due to the homes inherently leaky nature. Newer homes on the other hand, are becoming more sealed to the exterior environment, and are not allowing air to naturally infiltrate into the interior. Optimally, a balanced ventilation system is needed- a system that is designed to exhaust out, & draw in enough air to provide a good indoor environment, but not so much as to increase heating and cooling costs greatly. These systems also help ensure humidity is at levels low enough to discourage unwanted growth, such as mold and mildew, while not allowing such low levels as to be uncomfortable to live in. Most importantly, these systems allow for adequate air for the safe operation of the fuel burning appliances in your home. In a word, balance.
In the upcoming articles, I’ll talk more specifics about:
- Humidity in the home- How high is too high?
- Kitchen & bathroom fans- Are you using yours? ….you should be.
- Attic and crawlspace ventilation- Why does it really matter?
- Gas burning appliances- How do you know if they are getting enough air to operate safely? Can changing you kitchen hood fan be dangerous, even critical to your family’s health?
- Heat Recovery Ventilators (HRV)- What are they, and are they in your future?
