Learning the Ropes on Air Exchangers







When I first started working here, I admit I didn’t know much in the way of what the difference was between each system a home could have. Like you, I wasn’t sure how often I should have my filters cleaned or changed, or what was recommended by most HVAC companies in terms of service.


I decided to break down some of the basics -I’ll get more in depth later next month.







What is an air exchanger? An air exchanger, also known as a Heat Recovery Ventilator (HRV), or Energy Recovery Ventilator (ERV), is a system that helps provide proper ventilation in your home. It’s a fact that homes today are so well insulated that they can trap humidity and pollutants inside. Central ventilation and filtration effectively rid your home of those airborne pollutants and excess humidity, which helps protect not only your home but your family’s health!


Venmar offers a variety of different systems made to fit your specific home needs, all made with technology to keep your warm (or cool) air inside your home instead of losing it in the exhaust.


This video from Venmar helps to explain it with better graphics:









Manufacture recommendations for air exchangers is to clean or replace your filter every 3-6 months, and to have your system inspected and cleaned once every year to two years. Why the range? It depends on how many people live in your home, whether there are pets or tiny humans, if anyone smokes inside the home.







Here at Good Air Ventilation, we can service your air exchangers even if they aren’t Venmar, but we pride ourselves on installing exclusively Venmar products. If you are looking for more information on the systems we install, click here for our info page, or here to read directly from Venmar.
