You are right that the HRV is not 100% efficient. Most HRV's will transfer heat from the outgoing "stale" air to the incoming cold fresh air, but it will not transfer all of the heat.

The key is to not use your HRV more than you need to.

How much and HRV should be used is not the same for each family. If you have a large family, pets, and do a lot of cooking then you would want to use your HRV more than a couple who eat in restaurants half the time.

Personally, I'm not a fan of HRV installations that also vent bathrooms so hopefully you have normal exhaust fans in those rooms.

IMO, you should not be using your HRV in the summer on hot humid days. After all, it's a HEAT Recovery Ventilator.
