Your ductwork is the backbone of your home's comfort system. Even the best furnace won't perform without ducts that are designed, sealed and maintained the right way. We install, repair and clean, for new builds and retrofits across Halton.
Your ductwork is the backbone of your home's comfort system. Even the best furnace, air conditioner or heat pump won't perform properly without ducts that are designed, sealed and maintained the right way. At IKAD Mechanical, we provide expert duct installation, repair and maintenance to ensure air flows efficiently throughout your home. Properly designed and maintained ducts mean balanced temperatures in every room, lower energy bills, and cleaner, healthier air for your family.
Over time, ducts can develop leaks, gaps or build up dust and debris that hurt both comfort and efficiency. Our team specializes in sealing, repairing and cleaning duct systems to eliminate wasted energy and improve air quality. Whether you're building a new home, upgrading your current system or solving uneven heating and cooling issues, IKAD Mechanical delivers ductwork solutions that keep your home comfortable year-round while extending the life of your HVAC system.
For custom homes, additions and major renovations, we design the entire duct system around the actual airflow your equipment needs to move, measured CFM per room, properly sized trunks and branches, smooth fittings to keep pressure drop down. The result is a system that doesn't roar when the furnace fires and doesn't leave the back bedroom freezing.
A typical residential duct system leaks 20–30% of the air it's trying to move, into the attic, into the basement, into wall cavities, which is heated and cooled air you paid for. We test, find the leaks, and seal them properly with mastic or aeroseal.
Years of dust, debris and pet hair build up inside even well-maintained ducts. We use truck-mounted vacuum equipment and rotating brushes to clean trunks, branches, registers and the air handler itself.
Ductwork is only half the story, once the system is clean and tight, we measure and tune airflow at every register to make sure every room gets what it needs. See our air balancing service for details.
Most Halton homes we test have static pressure in the 0.9 to 1.2 inches of water column range. Manufacturer specs say total external static should be 0.5 inches. Why does it matter? Because the blower motor in your furnace was designed for 0.5, when it sees 1.0, it pulls more amps, runs hotter, throws codes intermittently, and dies five years early. The fix is usually a bigger return drop (10x20 instead of 8x14), a 4-inch media filter instead of a 1-inch furnace filter, or replacing flexible duct runs with rigid metal. We measure static at the furnace cabinet during every heating service call, it's the first reading we take.
A lot of Oakville and Burlington homes from the 1980s and 90s were built with builder-grade ductwork: undersized returns, no return on the second floor, flexible duct runs from a central trunk into individual bedrooms with sharp bends and crushed sections. We see this pattern hundreds of times a year. In the older parts of Burlington (Aldershot, Roseland) and east Oakville (Bronte, Glen Abbey) the basement ceiling height is tight, so the original installer compromised on duct sizing to fit the trunk. That's why we routinely see uneven heating in homes built before 2000. A proper retrofit replaces the trunk and resizes returns, that's where the real comfort comes from, not a bigger furnace. Read our guide to upstairs-too-hot-too-cold for the diagnostic walkthrough.
For an accessible duct system in a basement or unfinished area, manual sealing with water-based mastic and metal foil tape is fast, durable and cheap. For ducts buried in walls, ceilings, or sealed soffits, Aeroseal is worth the extra cost: pressurize the duct system, inject aerosolized sealant, the particles deposit inside the leaks and bridge them from the inside. We've cut measured duct leakage from 28% down to 4% on jobs where opening the ceilings wasn't an option.

In a two-storey Halton home, the most common causes are: (1) returns sized only for the main floor, so the second-storey rooms get pushed in but no air pulled out, (2) trunk takeoffs that branch off too close together causing pressure imbalances, or (3) leaky ducts in the attic dumping conditioned air into the roof space. Air balancing and targeted duct sealing usually fix it without ripping anything out, the full diagnostic walkthrough is in our upstairs hot/cold blog post.
Duct sealing for a typical 1,800–2,400 sq.ft. home is $850–$1,500, usually pays back in a winter or two from lower gas bills. Full duct replacement during a renovation is $3,500–$8,500 depending on complexity. New construction is priced per drawing, see our custom home mechanical scope page.
Honestly, less often than home services companies tell you. Healthy ducts in a home with good filtration get cleaned every 7–10 years. Skip it if you have allergies and a high-MERV filter. Get it done if you've just had a renovation, you can see dust drift out of the supplies, or you've inherited a hoarder house.
Yes, usually it's high static pressure (too small a return, too restrictive a filter) or a loose damper somewhere in the trunk. A static pressure reading at the air handler tells us in 5 minutes which it is. Often it's paired with an air balance for a complete fix.
