Ducts
Old leaky ductwork can account for 25-30% of energy waste in your home — meaning your HVAC system is working significantly harder than it should to heat and cool your living space. Home Upgrade Specialist installs new ductwork in new home builds and replaces old, leaky duct systems with sealed, insulated, highly efficient ducts across Los Angeles and Southern California.
Signs Your Ductwork Needs Replacement
Duct problems often go unnoticed for years while silently driving up energy bills and reducing comfort. Key signs include rooms that are consistently hotter or colder than the rest of the house, high energy bills despite a relatively new HVAC system, excessive dust accumulation on surfaces, musty or stale odors when the system runs, and HVAC systems that run constantly without reaching the set temperature. We perform duct inspections and leakage testing to identify the scope of the problem before recommending repair or replacement.
Duct Sealing vs. Replacement
Not all duct problems require full replacement. Accessible leaks at connections and joints can often be sealed with mastic sealant or UL-listed foil tape. For more severe cases — collapsed sections, flex duct that has deteriorated, ductwork in unconditioned attic spaces without proper insulation, or systems with significant design flaws — full replacement delivers a much better long-term result. We’ll give you an honest assessment of which approach makes more sense for your specific situation.
New Duct Installation
For new home builds, additions, or homes converting from ductless to ducted systems, we design and install complete duct systems using Manual D calculations to ensure proper airflow to every room. Properly designed ductwork is critical to HVAC performance — undersized or poorly routed ducts will prevent even the best HVAC equipment from performing correctly.
Duct Insulation in Los Angeles Attics
In Los Angeles, a significant percentage of ductwork runs through unconditioned attic spaces that can reach 140°F+ in summer. Uninsulated or poorly insulated ducts in these spaces can lose 20-30% of conditioned air before it ever reaches the living space. We properly insulate all ductwork to current Title 24 standards as part of every installation.
