Need Ductwork Installation in Largo?

Installing a new duct run in Largo typically runs $279 to $950 per run depending on length, attic access, and whether R-6 or R-8 insulation is required under Florida Energy Code.

We give you a flat-rate price before any work begins so you know the total before we touch anything.

Common signs in Largo homes include uneven temperatures between rooms, higher electric bills without a usage change, visible kinked or disconnected flex duct in the attic, dusty air despite regular filter changes, and musty smells from the vents. We carry a duct blaster on every truck and can test your system’s leakage rate free while we are on site for any service call.

For attic runs in Largo, R-6 or R-8 flex duct with a metalized outer jacket handles heat stress better than single-layer flex. For main trunk lines and plenums, 26-gauge galvanized rigid sheet metal is the most durable option. All connections get sealed with Hardcast mastic compound rather than duct tape, which fails in Tampa Bay attic heat within a few years.

Adding a single new duct run in Largo takes 2 to 4 hours for most jobs. A full ductwork system replacement for a 1,500 to 2,000 square foot home takes 1 to 2 days depending on attic access and system configuration. We handle the permit application and county inspection, and both are included in every ductwork quote.

Yes. Any new duct installation or full system replacement in Largo requires a permit under Florida Building Code Section 1006 and local county mechanical codes. We pull the permit and schedule the inspection on your behalf. The permit is included in your quote with no separate markup or add-on fee.

Yes. Adding supply and return air to a converted garage, bonus room, enclosed porch, or Florida room in Largo is one of our most common ductwork calls. We use Manual D airflow calculations to size the new run correctly so the new room gets adequate airflow without starving other rooms in the house.

Florida Energy Code requires a duct leakage test on any new or replaced duct system in Largo. The test uses a duct blaster to measure how much conditioned air escapes before reaching the rooms it serves. We perform the test as part of every ductwork installation and submit the results to the county for permit close-out. We can also test existing systems in about 30 minutes.

Flex duct in a Tampa Bay attic typically lasts 20 to 25 years if it stays intact. Rigid galvanized metal can last 30 years or more. The weakest point is always the connection seals. Duct tape dries out in Florida attic heat in as few as 3 to 5 years. We use Hardcast mastic on every connection, which outlasts the duct itself.

Yes, in most cases. Uneven temperatures are commonly caused by undersized duct runs, imbalanced airflow, or collapsed flex sections that restrict delivery. We perform a Manual D calculation before any ductwork project in Largo to make sure each room receives the correct airflow. Properly designed ductwork is the most reliable fix for comfort problems.

We install Johns Manville or Owens Corning R-6 and R-8 flex duct, 26-gauge galvanized sheet metal for trunk lines and plenums, and Hardcast 1402 or MasterSeal mastic for all connections. We do not use duct tape on any connection. All materials meet Florida Energy Code and ACCA Manual D requirements.

A: If your flex duct is 20 or more years old, has crushed sections, or you can see mastic tape that has separated, replacement usually costs less over 5 years than patching multiple problem areas. We inspect for free and show you photos from inside the attic so you can make the call yourself.

A: Most single-story Largo homes with 2 to 3 ton systems take one day. Two-story homes or homes over 2,200 square feet typically take two days. We schedule the work back to back so your AC is not off overnight.

A: Full duct system replacements in Pinellas County require a mechanical permit. We pull the permit, schedule the county inspection, and handle all documentation. The permit protects you at resale and ensures the work is inspected by a licensed third party.

A: We use R-8 flex duct as standard in Largo — two steps above the Florida Building Code minimum of R-6. R-8 reduces heat gain in a 140-degree attic significantly versus R-6, which means cooler air at the register and lower monthly bills.

A: The inspection and estimate are completely free. We visit, get into the attic, photograph every run, and give you a written quote. If you decide to move forward, the inspection cost is zero. If not, there is no charge. The only cost is the repair or replacement work you approve.
