Most Oldsmar homes built before 2000 still run the original flex duct, and after two decades in a hot attic that duct sags, crushes, separates at the collars, and loses its insulation value. A duct system that leaks 20 to 30 percent of its conditioned air into the attic makes your AC run longer, your back rooms stay warm, and your power bill climb. Other times the return side is simply undersized for the equipment, which starves the blower and shortens compressor life. We inspect the full duct run, measure static pressure, and tell you honestly whether sealing a few connections will fix it or whether a partial or full replacement is the smarter investment.

We specialize in providing top-of-the-line cooling solutions for your home or business. From Air Conditioning installation and maintenance to repair and replacement, we offer a comprehensive range of services to ensure your air conditioning system runs smoothly all year round.

Home Therapist installs and replaces ductwork throughout Oldsmar to current Florida Energy Code standards. Flex duct in a Florida attic typically lasts 15 to 20 years before the insulation degrades and the inner liner starts to tear, while properly sealed metal trunk lines last longer. On every Oldsmar install we right-size the supply and return based on a Manual D calculation, seal joints with mastic rather than tape, and support the runs so they do not sag or kink. We pull the county permit ourselves on any job that requires one and meet the inspector.
Pricing updated 2026. FREE estimates and FREE diagnosis on every ductwork job.
| Service | Price |
|---|---|
| Single duct run or repair | $279 to $650 |
| Return air drop add | $450 to $1,200 |
| Partial duct replacement | $1,200 to $3,500 |
| Full system duct replacement | $3,500 to $8,500 |
For most Oldsmar homes, a single duct run or repair ($279 to $650) handles a disconnected or damaged run, while a return air drop ($450 to $1,200) fixes a starved blower. Homes with a few bad runs usually fall in the partial replacement range ($1,200 to $3,500), and a complete re-duct of an older Oldsmar home runs $3,500 to $8,500 depending on the number of runs, attic access, and whether the trunk line is replaced. We give you a flat, written quote before any work begins, and financing with $0 down is available for qualifying customers. FREE estimates and FREE diagnosis on every visit.
Hot rooms, high bills, and a system that runs constantly are duct symptoms, not AC symptoms. We assess Oldsmar ductwork with pressure testing and airflow measurement before quoting anything. If replacement makes sense, we pull the permit, do the work, and schedule the Pinellas County inspection. Serving East Lake Woodlands, Bayside Meadows, and all Oldsmar ZIP codes 34677.

Energy Star measures duct leakage as a percentage of total system airflow. Florida homes average 27% duct leakage before replacement. In Oldsmar, where attic temperatures hit 155 degrees F and AC runs most of the year, that leakage equates to conditioning your attic instead of your rooms. 1980s homes in Oldsmar usually have flex duct with R-4 insulation -- adequate when installed but now degraded, with duct leakage rates averaging 25-35% in independent energy audits. Current code requires R-6 minimum for attic installation.. Every dollar you spend on electricity to cool your Oldsmar home, roughly 25 cents is going through duct leaks before it reaches a living space.
Oldsmar average duct leakage before replacement: 25-35%
We use Manual D calculation (required by Florida Energy Code) to size each supply branch for your specific home layout. Branch ducts run at low velocity to maximize dehumidification -- critical in Oldsmar's humidity. Main trunk lines sized for low friction loss. Supply registers positioned for maximum throw coverage. Return air grilles sized for low velocity (under 500 FPM). Every design accounts for your home's older vintage construction and Pinellas County climate zone requirements.
Manual D design: required by FL code, standard with our Oldsmar quotes
Day 1: Permit pulled from Pinellas County Building Department. Existing ductwork disconnected and removed from attic (we haul it away). New metal trunk fabricated or prefabricated sections installed. Day 1-2: Flex duct branches run and mastic-sealed at every connection. Registers and diffusers installed and balanced. Day 2-3: County inspection scheduled and passed. Post-installation duct leakage test confirms below 8%. In coastal Oldsmar, salt air accelerates corrosion on metal duct connectors and damper hardware. We use stainless-steel fasteners and marine-grade mastic sealant on all coastal installations to prevent the 2-3x faster corrosion rate seen in East Lake Woodlands and waterfront neighborhoods.. You receive the permit card and inspection result for your records.

Every ductwork replacement in Oldsmar includes: static pressure and airflow assessment, Manual D system sizing, permit from Pinellas County Building Department, complete removal of old ductwork, new R-8 insulated flex branches or R-8 wrapped metal trunk, mastic sealant at all connections, county inspection scheduling and attendance, and a post-installation duct leakage test. There's no separate charge for permits or inspection fees. The goal is a completed, inspected duct system with documented leakage below 8%.
Homes in East Lake Woodlands and other waterfront Oldsmar neighborhoods see salt-laden air infiltrate attic spaces through ridge vents and soffit openings. That salt air attacks galvanized metal duct fittings, causing rust that contaminates the airstream. We specify stainless-steel duct screws and marine-grade mastic on all coastal Oldsmar installations. We also check the plenum and air handler cabinet for rust at the assessment -- a rusty air handler in a coastal Oldsmar home is a replacement conversation, not just a ductwork one.

Installing a new duct run in Oldsmar 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. A full ductwork system replacement runs $1,800 to $8,500 for most Oldsmar homes. FREE estimates on every job. We give you a flat-rate price before any work begins so you know the total before we touch anything.
Common signs in Oldsmar 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 Oldsmar, 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 Oldsmar 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 Oldsmar 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 Oldsmar 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 Oldsmar. 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 Oldsmar 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: Yes. Mold spores circulating through HVAC systems are a recognized indoor air quality concern. The EPA and CDC both note that mold exposure can trigger respiratory symptoms, worsen asthma, and cause allergic reactions. In Oldsmar, where AC runs most of the year, contaminated ducts cycle air through every room continuously.
A: Surface-level cleaning can remove dust and loose debris, but mold embedded in the fiberglass inner liner of flex duct cannot be fully removed by cleaning. If the musty smell returns within weeks of cleaning, the liner is colonized. Replacement of affected runs is the lasting solution in that case.
A: Oldsmar ductwork mold is almost always caused by high attic humidity entering through leaky joints, condensation forming inside ducts during system off-cycles, or moisture entering through disconnected sections. Poor insulation accelerates the cycle. Sealing joints, upgrading to R-8 insulation, and replacing old flex breaks the pattern.
A: The most reliable signs are a persistent musty or earthy smell from registers, visible black or green deposits at duct boots, and worsening allergy or respiratory symptoms indoors. We use a camera to inspect runs during the free visit and document exactly what we find.
A: Ductwork replacement in Oldsmar starts at $279 for a single-run repair. Partial system replacement covering 3 to 5 major runs runs $2,500 to $5,500. Full system replacement in a typical 1,600 to 2,400 square foot home runs $4,500 to $12,000 depending on attic access and run count. Estimates are free and written.
