Ductwork Installation Services in Cambridge
Ductwork installation is needed in several common situations for Cambridge homeowners. Home additions, finished basements, and second-storey expansions all need duct extensions to deliver heating and cooling from the existing furnace. Kitchen and bathroom renovations may require duct relocations when walls move. Some heritage homes in Galt's core never had forced-air ductwork at all, relying on radiators, gravity furnaces, or electric baseboard heat. And post-war homes in Preston and Hespeler sometimes have original gravity-style ductwork from the 1950s that cannot deliver adequate airflow for a modern high-efficiency furnace.
When we install ductwork, we use galvanized steel properly sized for the furnace's blower capacity and static pressure requirements. For two-storey homes in south Cambridge and Champlain, we design supply runs that account for the stack effect, where hot air naturally rises, making upper floors warmer in winter and harder to cool in summer. We serve all Cambridge neighbourhoods and handle everything from a single-room extension for a basement bedroom to a complete system for a heritage home being converted from radiator heat.

PROLIFIC MECHANICAL REVIEWS
From Our Valued Clients
"Prolific Mechanical was fantastic. Quick response, fair pricing, and the technician explained everything clearly. Our furnace was back up and running the same day."
"Tom and his team installed our new AC unit and it works perfectly. Very professional, cleaned up after themselves, and the price was exactly as quoted."
"We had an emergency with our furnace on a cold January night. Prolific came out within hours and fixed the issue. Can't recommend them enough."
Why Duct Sizing Determines Performance
Proper duct design starts with calculating the required airflow for each room, then sizing trunk lines and branches to deliver that airflow within acceptable velocity and consistent static pressure limits. Undersized ductwork restricts airflow, strains the blower motor, and creates hot and cold spots. Oversized ductwork wastes material and space without improving performance.
We fabricate trunk lines and fittings from 26 gauge and 28 gauge galvanized steel for residential work, sized so they will not sag, compress, or deteriorate over time. Every joint is sealed with mastic and mechanically fastened. Because we operate our own in-house sheet metal fabrication shop, there are no long waits for outside orders, and custom fittings match your home's exact layout, which is especially important in Galt's heritage buildings where non-standard room dimensions and structural constraints rule out off-the-shelf components. Standard duct height is 8 inches, but we also fabricate 4 inch low-profile ductwork for duplexes, basement renovations, and any space where ceiling height matters. Sheet metal ductwork can be wrapped in foil-backed duct insulation to increase efficiency and reduce heat loss. We primarily work in galvanized steel and insulated flexible duct, with occasional stainless steel when a project calls for it.
Finished Basements and Home Additions
Finishing a basement is one of the most common renovation projects in Cambridge, and it always involves ductwork decisions. The existing trunk line along the basement ceiling was designed to serve the floors above and was never intended to heat and cool finished rooms below. Simply adding registers to the existing trunk is rarely adequate.
We extend the system with properly sized supply runs and return air paths for each basement room. Return air is critical: a finished room without a return path will be stuffy regardless of how much supply air you push into it. In older bungalows in Preston and Hespeler where basement headroom is tight, we use low-profile duct to minimize soffit depth and preserve ceiling height.
What to Expect During Your Ductwork Installation
On-Site Assessment
We measure your home, evaluate the existing duct system's capacity, and determine the scope of new ductwork needed. We verify that your furnace has sufficient blower output to handle the additional rooms or zones.
Design and Fabrication
We calculate airflow requirements for each room, design the duct layout, and fabricate custom trunk sections, fittings, and register boots in our sheet metal shop from galvanized steel to match your home's exact dimensions.
Installation and Sealing
We install the ductwork with sealed connections throughout, insulate any runs passing through unconditioned spaces, and connect supply registers and return grilles at each location.
Testing and Balancing
We measure airflow at each supply register, check total system static pressure at the furnace, and adjust branch dampers to deliver balanced, even conditioning to every room.
FREQUENTLY ASKED QUESTIONS
Can you add ductwork to a Galt heritage home that has no existing ducts?
Yes. Heritage homes in Galt that currently heat with radiators, baseboard heaters, or other non-ducted systems can be fitted with ductwork. The approach depends on the home's structure. In many cases, we route ductwork through the basement ceiling and up through interior walls to supply registers on each floor. For homes where duct installation would damage historic features, ductless heating and cooling systems may be the better option.
Should I replace old ductwork when installing a new furnace?
It depends on condition and design. If your existing ductwork is galvanized steel in good condition with adequate sizing, we clean, seal, and reuse it. If it is original to a 1950s or 1960s home with significant rust, poor sealing, or gravity furnace design, replacement is worth considering. Many Preston and Hespeler homes fall into a middle ground where we keep the main trunk, replace deteriorated branches, and seal all connections.
How long does ductwork installation take in Cambridge?
Adding duct runs to a single room typically takes one day. New ductwork for a finished basement with two to three rooms takes one to two days. In Preston and Hespeler bungalows with accessible basements, this work goes quickly. A complete new duct system for a Galt heritage home being converted from radiator heat may take two to four days depending on the building's structural complexity. We coordinate with your general contractor if the work is part of a larger renovation.
What is the difference between rigid metal ductwork and flexible duct?
Rigid galvanized steel ductwork maintains its shape permanently, offers the lowest airflow resistance, and lasts the life of the building. Flexible ductwork installs faster but creates significantly more airflow resistance due to its corrugated interior. In Cambridge's older homes around Galt and Preston, we often find crushed flex duct in attics and crawlspaces that has lost most of its airflow capacity. We use rigid steel for all trunk lines and branch runs, with flex duct used only for short final connections under six feet where rigid duct cannot physically reach.
