Same-day service in Poway & Sabre Springs — 24/7 emergency dispatch countywide.
Licensed & Insured · CA CSLB C-20 LicenseYour ductwork is the delivery system for everything your AC and furnace produce, and in Poway's older homes it is often the weakest link. Leaky, disconnected or crushed ducts in a 130°F summer attic can waste 20 to 30 percent of the cooling you are paying SDG&E to produce — air that never reaches your rooms.
The symptoms are familiar: rooms that never get comfortable, a system that runs constantly, high bills, and excess dust because leaky return ducts pull attic air into the house. These are duct problems, and no amount of new equipment fixes them.
We inspect and test your ductwork, seal leaks properly (not with the cloth 'duct tape' that fails in the heat), repair disconnected and damaged runs, and correct undersized ducts that choke airflow. It is often the highest-return HVAC work a Poway home can have done.

Signs of a duct problem
Some rooms never get comfortable
Weak airflow to distant or upstairs rooms usually means leaking, undersized or disconnected ducts, not a weak AC.
High bills with a system that runs constantly
When a third of your conditioned air leaks into the attic, the system runs longer to do less — expensive at SDG&E rates.
Excess dust in the home
Leaky return ducts pull dusty attic air into your living space, so you dust constantly no matter how good your filter is.
Whistling or air-rush sounds
Audible leaks or restrictions at duct connections point to sealing and airflow problems.
Hot attic, uneven temperatures
Poway's brutal attic heat makes duct leaks especially costly compared to milder climates.
Our process
- 1
Inspection and leak testing
We inspect the accessible duct runs and measure static pressure to find leaks, restrictions and disconnected sections.
- 2
Seal with proper materials
We seal joints with mastic and proper tape — not cloth duct tape, which dries out and fails in attic heat — for a lasting fix.
- 3
Repair and correct airflow
We reconnect and repair damaged runs and address undersized ducts that starve rooms of air.
- 4
Verify the improvement
We re-check airflow and static pressure so you can see the delivery to your rooms actually improved.
Why Poway attics punish leaky ducts
In a mild coastal climate, a small duct leak is a minor loss. In a Poway attic that hits 130°F-plus on a summer afternoon, every leak in a supply duct dumps expensive cold air into the hottest part of the house, and every leak in a return duct sucks that superheated attic air into your system. The result is a home that never quite cools, a system that runs nonstop, and SDG&E bills that make no sense given how new your AC is.
This is why we often recommend a duct inspection before anyone spends money on a bigger air conditioner. Sealing the ducts frequently solves the comfort complaint outright — and if you are replacing the system anyway, doing the ducts at the same time protects the efficiency you just paid for.
What affects the cost
Duct work ranges from targeted sealing to full replacement of a failed system. We scope it after inspection. What drives the cost:
Sealing vs. replacement
Sealing accessible leaks is modest; replacing collapsed or asbestos-era ductwork throughout is a larger project.
Attic access and layout
Tight, hot attics and complex duct layouts take more labor to work in safely.
Extent of damage
A few leaking joints cost far less than runs crushed, disconnected or degraded across the whole system.
Insulation upgrades
Re-insulating ducts in a hot Poway attic often pairs with sealing for the best efficiency gain.
