Advent Air Conditioning, Inc.

Hello William, looks like you're looking for https://advent-air.com/ which could possibly answer your question. Our business names are the same, but web address is different .... Adventair.com only provide services for New Construction Homes, Retrofit Replacement and maintenance for homes.... Not Motorhomes. Good luck :-)

Thank you Roger for interest in Advent air Conditioning. There are ways to make a 80% furnace work on a foamed attic but morally and ethically it isn't the right thing to do because it puts you and your family at risk. On a foamed attic there's no way to bringng in fresh air or disposing of the harmful fumes and you take a risk of dumping poisonous gases into your home. 90% furnaces use fresh air from outside and exhaust poisonous gas out to the atmosphere not into the home. Advent does NOT recommend using a 80% furnace on an encapsulate home. We would be glad to help in anyway possible but we do things right 100% of the time or we just don't to it. Thank you again for your interest and we look forward to helping you in the future. Thank you, Tammi Douglas
