Venting About Ventilation

via Lennox

The topic of ventilation may not be at the top of the list of things to ask about during your next Phoenix air conditioning service, but it should be. As modern homes become more and more energy efficient and airtight, issues surrounding poor ventilation arise without you even realizing it.

Why should I ventilate?

If you were to ask your Phoenix AC replacement specialist, they will tell you that without proper ventilation your home is essentially a trap for airborne pollutants and excess moisture. Think of your house as an airtight jar, and you’re a person living inside of it. Over time carbon monoxide, chemicals, gases from household appliances, and extra moisture accumulate in the jar. If the jar is only opened for short periods of time as you come and go, the increasing concentration of pollutants can become harmful to your health. The additional humidity is also the perfect condition for mold and mildew growth, even further contaminating your breathing air. Ventilation is like creating an opening in the jar at both ends, saving the day by letting fresh air in, and pollutants and humidity out.

Ok, what are my options?

We’re glad you asked! There are two main categories of ventilation solutions, with different options available depending on your need and the structure of your house.

  1. Natural Ventilation: This option includes clerestories (raised roofs with windows that allow light and air) and solar chimneys, which use solar heat and pressure to drive air through vents. Simply cracking a window to allow for airflow falls into this category as well. These approaches are energy efficient but do not allow any heated or cooled air to escape through openings. It is also important to remember that natural ventilation doesn’t guarantee proper air circulation, may not be effective under certain circumstances, and doesn’t provide humidity control.
  2. Mechanical Ventilation: This method uses a system of fans and HVAC ducts to force fresh air through your home. There are many types of mechanical ventilators. For example, Goodman offers high-quality Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) to meet your needs depending on what climate you live in. This approach does require energy to operate; however, each ventilation system differs. Lennox also provides HRV and ERV options that recirculate indoor air with fresh air from outdoors, without wasting additional energy. During your next Phoenix AC replacement appointment, ask about which ventilation option is best for you.
