Heating and cooling systems that monitor and maintain indoor air quality are becoming increasingly popular, according to Forbes.
What most older houses have now for ventilation are bathroom fans and kitchen range hoods to remove the bad air. Older homes may be leaky, so while you are getting some fresh air, you have no control over where it’s coming from. On top of that, your HVAC system won’t work efficiently. Newer homes are more tightly built. So, yes, they’re more efficient from an energy standpoint, but you may not be getting the fresh air you need.
Enter the HRV and ERV. Although they’ve been around a while, many people don’t know about them. But you should get to know them because you’re going to be hearing about them a lot in the next few years as more people focus on IAQ. Basically, these devices pull out the bad air and replace it with good air. (If you have an older home, the first thing you’d need to do is tighten it up for either of these to do their best work.)
