Most residential AC installations in Chattanooga are completed within a single day to a couple of days, depending on system complexity and whether ductwork modifications are needed. Larger homes or units requiring duct repair may take longer.
The right AC size depends on square footage, insulation, window placement, and local climate factors specific to Chattanooga, TN. A technician typically performs a load calculation during the free quote visit to recommend the correct unit size.
In many cases existing ductwork can be reused if it's in good condition and properly sized for the new unit, but older or leaky ducts may need repair first. An inspection during the quote process helps determine whether duct work is needed alongside installation.
