With the hot summer months here, your place of business will need some cooling down. There is nothing that will turn away customers and clients like a hot stuffy store or office. With a central air conditioning system, your building will rely on ductwork in the walls to funnel cool air into the spaces of the building that need it, but unfortunately, it is a system that is prone to problems.
Leaking ducts can cost you money in additional energy spent getting the air cool enough. A leak that is vented into a crawlspace or an attic will both lose the cool air and pick up warm, possibly odorous air from the area and bringing it into your workspace.
Leaks commonly occur closer to the HVAC unit due to the higher pressure that the air is under in the ducts there, so that is a good place to check first. Using thermal imaging can also help in finding the source of the problem.
