But there is no specification in the International Residential Code for a minimum distance between the dryer vent termination and an air conditioning condenser. The IRC defers to manufacturer’s instructions and only states that “if the manufacturer’s instructions do not specify a termination location, the exhaust duct shall terminate not less than 3 feet (914 mm) in any direction from openings into the buildings.” But the air conditioning condenser shown in the close-up photo below sits 8 feet away from a dryer duct termination and it was heavily caked with dryer lint on all sides. So, keeping the dryer duct termination and a/c condenser as far apart as possible is the best solution.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
