When does duct repair pay for itself?

When leaks are costing more than the fix. Losing 25% of cooled air in an Orlando home wastes roughly $500–$1,000 a year in electricity, so a $1,500 sealing job can pay back in under 2 years. Warning signs: rooms that never cool, a hot attic full of cold air, ducts disconnected at the boots, and bills that climbed without explanation.

Should I repair ducts or replace them entirely?

Repair or seal if the duct system is under about 15 years old with localized damage — $200–$800 per section. Replace ($2,500–$8,000) when flex duct is brittle and crumbling, the inner liner is collapsing, ducts are undersized for the system, or damage covers most runs. Replacing ducts alongside a new AC install is the cheapest time to do it.

Duct Repair Cost in Orlando (2026): Sealing to Full

Q: How much does duct repair cost in Orlando?

In Orlando in 2026, duct sealing costs $500–$2,500, individual section repairs cost $200–$800 per section, and full duct replacement runs $2,500–$8,000 depending on home size and attic access. Diagnosis starts with an $89 service call from Smart Home Air & Heat, applied to the work.

Q: How much cooled air do leaky ducts lose?

Typical homes with duct leaks lose 20–30% of their cooled air into the attic before it ever reaches a room. In an Orlando summer that can mean $40–$90 a month in wasted electricity — cooling a 130-degree attic instead of your house. Sealing at $500–$2,500 often pays for itself in 1–3 years.

Q: Is duct cleaning a scam?

The $49–$99 'whole-house duct cleaning' coupon usually is — it's a bait visit that ends in a mold-scare upsell of $1,000–$3,000. Legitimate duct cleaning exists for specific cases (post-renovation dust, verified contamination, rodents), but for most Orlando homes the real problem is leaks, not dust. Sealing fixes what cleaning can't.

What does duct sealing, repair, and replacement cost in Orlando?

Here's the full scope-by-scope table for July 2026. Every job starts with an $89 inspection, applied to the work.

Orlando Ductwork Costs by Scope (July 2026)
Service	Orlando Price Range	When It's the Right Fix	Typical Payback
Duct inspection & leakage assessment	$89 (applied to work)	Always the first step	—
Single section repair / reconnect	$200–$800 per section	Disconnected boots, crushed or torn runs	Months — a fully disconnected duct is pure waste
Duct sealing (mastic / whole-system)	$500–$2,500	Ducts sound but leaking at joints and connections	1–3 years on electric savings
Partial replacement (several runs)	$1,200–$3,500	Localized brittle or rodent-damaged flex duct	2–4 years
Full duct replacement	$2,500–$8,000	Brittle liner, undersized design, damage on most runs	Comfort + efficiency for 20+ years
"Whole-house duct cleaning" coupon	$49–$99 advertised	Rarely — usually a mold-scare upsell visit	Often ends in a $1,000–$3,000 pitch

Full replacement pricing depends on home size, number of runs, and attic access — a one-story 1,600 sq ft home with easy access lands near the bottom of the range; a two-story home with tight attic chases lands near the top. See our ductwork services for how the work is done.

How much cooled air are your ducts actually losing?

Typical leaky systems lose 20–30% of conditioned air before it reaches a single room — you're paying to cool a 130° attic.

In an Orlando summer, a 25% duct loss on a typical home wastes roughly $40–$90 per month in electricity. That's why a $1,500 sealing job routinely pays back in under two years. It also explains the classic Florida symptoms: one bedroom that never cools, a system that runs constantly, and humidity that won't drop even though the AC seems fine. Before blaming the equipment — or buying a bigger system — get the ducts tested. An oversized replacement on leaky ducts is the most expensive way to fix the wrong problem (compare at new AC unit costs).

20–30% of cooled air — gone into the attic.

That's the typical loss in homes with leaky ductwork. On an Orlando electric bill, it can mean $500–$1,000 a year spent cooling a space nobody lives in.

When is duct cleaning a scam — and when is repair the real answer?

The $49 "whole-house duct cleaning" coupon is bait about 90% of the time. Leaks, not dust, are the usual Orlando duct problem.

The playbook: a crew arrives for the $49 cleaning, "discovers" mold, and pitches a $1,000–$3,000 remediation on the spot — often with a flashlight photo of ordinary dust. Legitimate duct cleaning does exist for specific situations: post-renovation drywall dust, verified contamination after a leak, or rodent intrusion. But cleaning does nothing for the actual epidemic in Orlando attics — flex duct joints leaking at every connection. Sealing fixes what cleaning can't touch.

Red flags: coupon pricing, instant mold "diagnosis" without lab testing, pressure to sign today, no duct leakage measurement
Green flags: written leakage assessment, photos of the actual damage locations, itemized scope, mastic (not just tape) for sealing

"I've crawled a thousand Orlando attics. I can count on one hand the ones that needed cleaning — and I've lost count of the ones blowing a quarter of the homeowner's cold air straight into the insulation."

Should you repair your ducts or replace the whole system?

Repair/seal if ducts are under ~15 years old with localized damage. Replace if flex duct is brittle, the liner is collapsing, or the design is undersized.

Florida attic heat cooks flex duct — after 15–20 years the outer jacket cracks and the inner liner sags. Patching brittle duct is throwing $200–$800 sections at a system that will keep failing. Replacement ($2,500–$8,000) makes sense when damage covers most runs, and the single cheapest time to do it is alongside a new AC installation, when crews and permits are already on site. The same repair-vs-replace logic that applies to equipment applies to ducts — see the repair-vs-replace framework. A duct check is also part of every $89 21-point tune-up.
