Lennox Heat-Recovery Ventilators

Air-to-Air Heat Exchangers

The introduction of outdoor air is essential to keep a home's air fresh and healthful, but it runs counter to the principles of efficient heating. You can open windows, but when you do, your conditioned air escapes and your heating system has to work harder. If you are striving to be efficient and reduce energy consumption, you need an alternative system that complements your efforts instead of defeating them.

The best solution is a heat recovery ventilator that transfers heat from your heating system to the outdoor air as it is brought inside so that your system does not have to work harder to make up for the addition of cold air. MacFarlane Energy's air quality experts can help you determine if your home can benefit from air-to-air heat exchange.
