How Much Does Ductwork Cost in Denton?

Ductwork in Dentonstarts at $85 for a static pressure diagnostic (waived with any repair). Most homes need 2-5 targeted repairs, not a full duct redesign. We're flat-rate, which means the price quoted before we start is the price you pay at the end. Frosty Club members save 10-15% on every job.

Why DentonHomeowners Trust Frosty's for Ductwork

Denton has the most ductwork variety of any city we serve. Downtown Denton, the historic square, Wolflin, and Oak Gardens are full of prewar homes (1900s-30s) where central air was retrofitted decades later. The original ductwork is almost always undersized — trunk lines that belong on a 1.5-ton system trying to feed a 3-ton. Supply registers are cut into plaster walls, returns are a single 14x20 grill doing the work of two, and the flex duct in the attic is 1980s-vintage with tape that gave up years ago. I routinely measure 30-40% air leakage in these homes with a Duct Blaster test. That's why the upstairs bedrooms are always 10°F off from the living room — not a thermostat issue, not a refrigerant issue, a duct sizing and sealing issue.

UNT and TWU rental stock — the postwar ranch homes from the 1950s-70s near campus — have a different duct problem. The original rigid metal trunk is usually intact, but every branch run has been patched, replaced piecemeal with mismatched flex, or crushed where someone stored Christmas decorations on top of it in the attic. And on the rural outskirts with acreage homes, the issue is often ductwork that runs 40+ feet through an unconditioned attic with R-4 insulation in 150°F heat, losing most of its cooling capacity before it reaches the last bedroom. Robson Ranch homes, being 2000s+, generally have adequate ductwork from day one — the calls we get there are sealing jobs ($350 flat), not full replacements.

Every ductwork job in Denton includes a before-and-after static pressure reading — we measure what your blower is fighting against before we start and prove the improvement after we're done. Target on a healthy residential system is under 0.5 inches of water column; most downtown Denton homes we first visit are running 0.9-1.3 (way too high, which means the blower is working harder and failing sooner). We don't offer duct insulation as a standalone product — if ducts are that deteriorated, they need full replacement, not a band-aid.
