Most underperforming HVAC systems in Burnaby aren't equipment problems — they're ductwork problems. Undersized trunks, poorly sized branches, leaky joints, and missing dampers can cost 25–40% of your system's rated efficiency before the air ever reaches a room. New ductwork or a major retrofit fixes that.
We design ductwork using Manual D — the industry standard for residential duct sizing — not rule-of-thumb sketches. The design accounts for friction loss, register count, return path sizing, and balanced static pressure across every zone.
All new and retrofitted ductwork is sealed with mastic at every joint, R-6 to R-8 insulated where it runs through unconditioned space, and balanced at commissioning so every room hits its target airflow.

Why Burnaby Ductwork Is Often the Real Problem
Cascade Heights, Sullivan Heights, and Willingdon Heights split-levels built in the 1960s–1980s commonly have ductwork sized for the original 60% AFUE furnace running at higher temperature rise. When the furnace was upgraded to a modern 95%+ unit moving more air at lower temperatures, the ducts became undersized — high static pressure, poor airflow to far rooms, blower motor stress.
Burnaby Heights and Capitol Hill heritage homes that had ductwork added in retrofits often have flex duct snaking through finished walls and over joists. Flex duct loses 30–50% of its rated capacity when bent past 90° or compressed. Replacing with rigid metal trunks where possible recovers the lost airflow.
Multi-storey townhomes in Brentwood and Lougheed are notorious for short duct runs to the upper floor that don't get properly balanced. Adding zone dampers or rebalancing the existing layout often fixes the “upstairs is always hot, downstairs is always cold” problem without replacing equipment.
What Burnaby Homeowners Say
“Our top-floor unit was unbearable in July. They installed a quiet ductless system in two days and walked us through the strata approval beforehand. Zero issues, much cooler home.”
“1982 boiler was on its last legs. They replaced it with a high-efficiency combi unit, re-piped a few corroded sections, and pulled the gas permit through Technical Safety BC. Heat is more even than before.”
“We bought a 1999 build and the inspection flagged Kitec. They re-piped the whole house with PEX in three days, fixed the manifold, and only opened drywall where they had to. Clean job.”
