When should I get an HRV? Does my house need one?

Before upgrading your home’s ventilation system to an HRV, it’s important to understand the state of your home to assess whether a HRV will be a suitable upgrade.

There are three common scenarios with which a HRV upgrade would benefit a home:

• Poor Indoor Air Quality
• Excessive Moisture (condensation or mould issues)
• Enclosure Upgrade Already Planned

If your home’s current ventilation system is inadequate, it’s important to investigate further to see if the issues can be resolved within the existing system. If they can’t be fixed, it may be time to upsize your existing ventilation system or invest in an ERV or HRV. In general, HRVs are recommended for airtight homes where a balanced system is required. For expert advice consider having an EnerGuide home evaluation and speak to a program-qualified energy advisor. The energy advisor can assess your home and see whether a HRV or ERV is right for your home.
