Can I install my new gas furnace in my attic? Back
Usually, subject to your local code requirements. All of our furnaces are compatible for horizontal installations and are approved by the manufacturers for use in attics.
When installing a high efficiency furnace be certain that the ambient air in the attic does not go below freezing as this may cause the condensate drain to freeze and create a blockage.
There must at least enough heat in the attic to maintain the temperature above freezing for condensing-type, high efficiency furnaces. (90+ efficiency). This limitation does not exist for standard efficiency (80%) furnaces.
