Your ductwork is the hidden reason your system underperforms
You can have the best HVAC unit on the market — but if the ducts are undersized, leaky, or poorly routed, you are wasting 30-40% of your conditioned air before it ever reaches the room.
Rooms that never get comfortable
One room is freezing, the next is sweltering. Your system is working fine — the ducts just cannot deliver air where it needs to go
Loud whooshing and rattling
Undersized ducts create turbulent airflow that whistles and bangs. Poorly sealed joints rattle every time the system cycles on
High bills despite a new system
You just installed a high-efficiency unit but your bills barely changed. Leaky ducts lose 25-40% of conditioned air into walls, attics, and crawl spaces
Renovation with no plan for airflow
You knocked down a wall, added a room, or converted a space — but nobody redesigned the ductwork. Now the whole system is unbalanced
We spent $15K on a new HVAC system and still had hot spots everywhere. Art HVAC found that our 30-year-old ductwork was 40% undersized. After the duct modification, it was like having a brand new building.
WHAT WE DO
Complete Ductwork Solutions for Every Project
From full new-construction duct systems to targeted modifications that fix a single problem area — we design, fabricate, and install ductwork that actually delivers.
New Ductwork Installation
Residential & Commercial Build-Outs
Complete duct system design and installation for new spaces. We calculate airflow requirements for every room, custom-fabricate sheet metal duct runs, and balance the entire system for even temperature distribution.
Ductwork Modification
Fix Airflow After Renovations
Added a room? Knocked down a wall? Changed the layout? We redesign and modify your existing duct system to match the new space — adding runs, resizing trunks, and rebalancing the entire network.
Duct Sealing & Repair
Stop Losing Conditioned Air
Leaky duct joints, disconnected runs, and crushed flex duct waste up to 40% of your conditioned air. We locate every leak with pressure testing and seal them permanently — not with tape, but with mastic and mechanical fasteners.
QUALITY MATERIALS
Built with the Industry's Best Materials
We use commercial-grade galvanized sheet metal, insulated flex duct from trusted manufacturers, and code-compliant fittings on every job. No shortcuts, no cheap materials — because your duct system needs to last as long as your building.

HOW IT WORKS
From Airflow Problems to Perfect Delivery
Every ductwork project starts with understanding your space and ends with verified, balanced airflow in every room.
Airflow Assessment
We measure airflow at every register, test duct pressure, and identify exactly where your system is losing performance — hot spots, leaks, undersized runs, or poor design.
Custom Design & Quote
We design the duct layout using Manual D calculations, specify materials, and provide a detailed, line-item quote. You know exactly what you are getting and what it costs before we start.
Fabrication & Installation
We fabricate custom sheet metal components in our shop and install everything on site — trunk lines, branches, transitions, registers, and returns. Every joint is sealed and fastened to code.
Balance & Verify
After installation, we measure airflow at every register and adjust dampers until every room receives the correct volume of air. You get verified, even comfort — not guesswork.
FAQ
Questions We Hear Every Day
Practical answers about ductwork from licensed HVAC engineers.
Common signs include rooms that are always too hot or cold, excessive dust, whistling or banging noises, and high energy bills despite a newer HVAC unit. If your system is working hard but rooms are not comfortable, the ducts are almost always the bottleneck. We offer free airflow assessments to pinpoint the issue.
Absolutely — most projects are modifications, not full replacements. We can add runs to new rooms, resize undersized trunks, seal leaky joints, add dampers for zone control, and reroute ducts around renovations. We only replace what needs replacing.
Studies show that typical duct systems lose 25-40% of conditioned air through leaks. In a building spending $500 a month on energy, that is $125-200 wasted every month. Duct sealing typically pays for itself within 6-12 months through energy savings alone.
It depends on the scope. Minor modifications like adding a register or sealing joints typically do not require permits. New duct installations and major modifications in commercial spaces require DOB permits. We handle all permitting and coordinate inspections — you never have to deal with the paperwork.
A targeted modification — adding a run or sealing leaks — typically takes 1-2 days. A full duct system for a residential build-out takes 3-5 days. Commercial projects vary based on size and complexity. We always provide a detailed timeline upfront and work around your schedule.
