Do I need a HRV or ERV?
An HRV is a better choice if you often have an overly humid house during winter, while an ERV is superior if your house is too dry.

Whats the difference between HRV and ERV?
What is the difference between an HRV and an ERV? HRVs and ERVs are similar devices in that both supply air to the home and exhaust stale air while recovering energy from the exhaust air in the process. The primary difference between the two is that an HRV transfers heat while an ERV transfers both heat and moisture.
Do I need an ERV?
Why Do You Need An ERV? An energy recovery ventilator can be a helpful tool if you’re struggling with your indoor air quality. If your home air smells or tastes stale and there’s nothing that fans or air conditioning can do to help with it, an ERV can be a good piece of equipment to change that.
Where do you put ERV?

Should I run my HRV in the summer?
The answer depends on your home’s air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.
Does an ERV remove humidity?
While similar to HRVs, ERVs also remove humidity from the air before it is brought into the home – greatly reducing cooling costs. ERV ventilation solutions are balanced, energy recovery ventilation systems, boasting the lowest operating cost of ventilation options.
Can an ERV be installed outside?

Why does an HRV need to be balanced?
Why Is a Balanced HRV Important? To get the most benefit from the air conditioning or heating system, it’s important for a homeowner to keep all the doors and windows closed, and when you do that in a modern house, there are no gaps through which air can pass to equalize indoor air pressure.
What does it mean to balance an HRV?
HRV Balance reflects how your day to day patterns of stress and recovery balance out over weeks. If your balance leans more towards strain than recovery, your HRV is likely to trend down. If you’re striking an optimal balance between pushing and rebounding, your HRV will maintain, or even improve over time.
