An ERV system can help to keep your indoor humidity at a desirable level. That can help your home stay comfortable and prevent damage to your furniture. An ERV can also filter out odors, pollen, and other airborne contaminants. This reduces potential allergy or asthma triggers. Because your heating and cooling system can stay cleaner, it can run better and last longer.
When you try to ventilate your home by opening a window, you end up losing large amounts of air. Any energy that went into heating or cooling that air goes out the window at the same time. When an ERV transfers heat energy between old and new airstreams, it pre-heats or pre-cools the new air. That keeps the energy in the system, and that saves you money in the long run.
