We review your plans, assess unit count and layout, and provide a detailed, fixed-price quote.
We prepare permit drawings for HVAC and plumbing and coordinate submissions with the city.
Our licensed technicians complete all rough-in work on your timeline, coordinating around other trades.
We complete all finish work, commission systems, and attend city inspections to obtain sign-off.
Yes. ICS is licensed to pull both HVAC and plumbing permits in Toronto and throughout the Greater Toronto Area. We manage all permit applications, inspections, and final sign-offs as part of our scope.
We work on duplexes, triplexes, fourplexes, and larger multi-unit residential builds — including purpose-built and conversion projects. We're experienced with both new construction and gut-renovation multiplexes.
Absolutely. We're accustomed to working within a general contractor's schedule and coordinating rough-in timing with framing, drywall, and other trades to keep your project on track.
The right system depends on your unit layout, budget, and energy goals. We commonly install individual high-efficiency furnaces per unit, multi-zone heat pump systems, or shared hydronic boiler systems. We'll recommend the most cost-effective option for your specific build.
Many of the systems we install — including heat pumps and high-efficiency furnaces — qualify for the Canada Greener Homes Grant and other provincial incentive programs. We can advise on eligible equipment during the design phase.
