Signs Your Ducts Are Costing You Money

In Phoenix, most homes have ductwork running through unconditioned attic space. Attic temperatures can exceed 160°F in summer. When ducts leak or aren’t properly insulated, the hot attic air mingles with your conditioned air — and you pay for it on every utility bill.

The Department of Energy estimates that leaky ducts waste 20–30% of conditioned air before it reaches the living space. In Phoenix, where cooling runs 9+ months a year, that adds up to hundreds of dollars annually.

Some rooms are noticeably hotter or colder than others

Your system runs constantly but never quite gets comfortable
You notice musty or stale odors when the AC kicks on

How We Fix It

We don’t guess. We pressure-test your duct system to quantify exactly how much air is being lost and where. Then we give you options — seal, repair, or replace — with honest cost-benefit guidance on each.

Pressure test first

We measure leakage before and after so you can see the actual improvement — not just trust our word for it.

Mastic sealant, not duct tape

Duct tape fails within 2–3 years in Arizona heat. Mastic sealant is the code-compliant, permanent solution.

Airflow balancing

After sealing or replacement, we balance the system so every room gets the airflow it needs.

Ductwork Services We Provide

Sealed tight. Sized right. Built to last in Arizona heat.

Duct Sealing

We locate leaks using pressure testing and airflow diagnostics, then seal joints and connections with mastic sealant — the proper, durable solution. Not duct tape. Mastic.

Best for: ducts that are structurally sound but leaking at joints

Duct Repair

Damaged sections, collapsed flex duct, disconnected branches — we repair or replace the problem segments without tearing out the whole system.

Best for: localized damage, rodent damage, or collapsed sections

Full Duct Replacement

Older homes often have undersized, deteriorated, or improperly installed ductwork that can't be fixed incrementally. We design and install a complete duct system sized to your equipment and your home.

Best for: homes 20+ years old, major renovations, or whole-system replacement

New Construction Ductwork

We work directly with builders during rough-in on new construction. Properly sized, code-compliant duct systems that pass inspection and perform correctly from day one.

Best for: new builds, additions, room conversions
