Custom duct fittings are fabricated in Waywest's own sheet metal shop, so ducts are built to the building rather than forced from off-the-shelf parts.

Why ductwork matters

A furnace or heat pump can only deliver comfort through the ducts attached to it. Undersized, leaky or poorly laid-out ducts cause:

  • Rooms that never reach temperature
  • Noisy, whistling registers
  • High energy bills
  • Short equipment life from the blower working too hard
  • Dust drawn in from crawlspaces and attics
  • Heat pumps that underperform or freeze up

Many older Island homes have duct systems that were designed around a furnace decades ago and never revisited, even as rooms, insulation and equipment changed.

Ductwork services

New duct systems for new construction, additions and homes converting from baseboard or oil to a heat pump.

Modifications for heat pumps. Enlarging trunks, adding returns and resizing supplies so a heat pump gets the airflow it needs — see heat pumps.

Hot and cold room fixes. Adding or rerouting runs, balancing dampers and returns.

Duct sealing and insulation, especially in crawlspaces and attics.

Repairs to crushed, disconnected or damaged ducts.

Commercial ductwork for offices, retail and multi-unit buildings.

Built in our own shop

Most HVAC contractors order standard fittings and adapt them on site. Waywest has a sheet metal shop in Nanaimo that fabricates custom transitions, plenums, offsets and fittings to exact dimensions.

That matters in real houses, where joists, beams and plumbing are never quite where the standard part expects. Custom fittings mean smoother airflow, less noise, and a cleaner installation. See custom HVAC ductwork.

How we approach a duct project

  1. Assess the system — duct sizes, layout, leakage and the equipment it serves.
  2. Measure airflow and static pressure to see how hard the system is working.
  3. Design the changes based on the load of each room.
  4. Fabricate fittings in our shop where standard parts will not fit well.
  5. Install, seal and insulate the ductwork.
  6. Balance and test airflow to each room.

Common questions

Can my existing ductwork be used with a heat pump?

Often, but not always. Heat pumps typically need more airflow than the furnace they replace, and ducts that were sized for a furnace can be too small, causing noise and poor performance. Waywest checks duct sizes and static pressure before recommending whether ducts can be reused or need modification.

Why is one room always colder than the rest of the house?

The usual causes are an undersized or long supply run, a crushed or disconnected duct, poor return air from that room, or a room with much higher heat loss than the rest of the house. Measuring airflow at the register shows which it is.

How much heat is lost through leaky ducts?

Duct leakage can waste a meaningful share of the heating and cooling a system produces, especially when ducts run through unheated crawlspaces or attics. Sealing joints and insulating ducts in unconditioned spaces is one of the more cost-effective efficiency improvements.

Should I get my ducts cleaned?

Duct cleaning helps when there is visible debris, construction dust after a renovation, pest contamination or mould. It is not a substitute for good filtration and sealed return ducts, which prevent most dust problems in the first place.
