What This Involves
New duct installation is a design exercise before it is a construction task. Every run has to be sized using Manual D calculations that account for the home's Manual J heating and cooling load, the equipment's rated airflow, and the friction rate of the duct material chosen, whether that is flexible duct, rigid sheet metal, or fiberboard. Installing ductwork without proper sizing is one of the most common causes of the comfort complaints we get called out to fix on homes with brand-new equipment, because an undersized trunk line or too many long flex runs off a single takeoff will starve rooms of airflow no matter how well the equipment itself is running.
For a full installation, we start by mapping supply and return locations against the home's layout, then run trunk lines sized to carry the full system tonnage with room to spare, branching into properly sized flex or rigid takeoffs for each register. We keep flex duct runs as short and straight as possible, since every 90 degree bend in flex duct has roughly the same airflow resistance as several extra feet of straight run, and long, sagging runs are a common source of poor performance in additions and remodels where ductwork gets snaked around existing framing. Return air gets particular attention, since undersized returns create negative pressure that can pull attic or crawlspace air into the living space through any gap in the building envelope.
New installation projects come up most often for room additions, converted garages, finished attics, and full system replacements where the old duct system is too small, too deteriorated, or configured for equipment that no longer exists in the home. Georgetown's mix of 1970s and 1980s ranch homes alongside newer two-story construction means duct routing challenges vary a lot by neighborhood, older single-story homes often have generous attic space but undersized trunk lines from a smaller original system, while newer two-story homes need careful routing to get adequate supply to upstairs bedrooms without oversizing the downstairs zones. Installation cost depends heavily on scope, from a single new run for a room addition in the 400 to 900 dollar range up to full-home duct replacement, which we always price after an on-site load and layout assessment rather than a phone estimate.
