Adding additional cold air returns to your home's air conditioning duct work system can be an important step to making your home duct work function well. Insufficient return air pressure can lead to a number of problems, such as inefficient air handler operation due to inability to push enough air through the system.
The Florida Building Code has instituted new requirements for duct work to help improve the efficiency of heating and air conditioning systems .
Those changes affect both the homeowner and the AC Contractor. The 2010 Florida Building Code 18.104.22.168.1 requires:
Duct sealing upon equipment replacement (mandatory). At the time of the total replacement of HVAC evaporators and condensing units, all accessible joints and seams in the air distribution system shall be inspected and sealed where needed using reinforced mastic or code approved equivalent and shall include a signed certification by the contractor that is attached to the air handler unit stipulating that this work has been accomplished.
The new rule will require HVAC contractors to inspect the overall condition of your ductwork and incorporate any needed repairs into the scope of your installation.
