HVAC system retrofits

HVAC retrofit consulting for Ontario buildings

Aging boilers, chillers and rooftop units cost more to run every year. We help building owners plan and deliver HVAC retrofits that cut energy use, improve comfort and indoor air quality, and qualify for every incentive available.

What we work on

Systems we retrofit

We focus on the mechanical systems that drive most of a building's energy bill, in schools, institutional and commercial buildings, and homes.

Boilers and heating plants

Condensing boiler upgrades, right-sizing, pumping sequences and reset controls.

Chillers and cooling

Chiller replacement options, part-load efficiency and cooling plant optimization.

Rooftop and make-up air units

Replacement, economizer repair, heat recovery and right-sized make-up air.

Unit ventilators and classrooms

Classroom ventilation upgrades that meet fresh air requirements without wasting heat.

Air-source heat pumps

Cold-climate heat pump options for electrification and hybrid systems.

Ventilation and heat recovery

Demand-controlled ventilation, VFDs on fans and pumps, and energy recovery.

How it works

From assessment to commissioning

Site assessment

We inspect the equipment, review nameplate data, utility bills and maintenance history, and identify what is failing or oversized.

Options and business case

You get clear options with costs, energy savings, payback and incentive estimates, so you can compare like-for-like against high-efficiency.

Scope and tendering

We help define the scope of work and support contractor pricing, so bids are complete and comparable.

Construction oversight

As your owner's representative, we track progress, review submittals and resolve site issues.

Commissioning and closeout

We verify the system runs as intended and collect the documents needed for incentive payment.

Why Toulaye

Independent advice, owner-side

Not tied to one brand

Recommendations are based on your building and budget, not on what one installer sells.

School board experience

We manage multi-school HVAC upgrade programs as owner's representative for an Ontario school board.

Incentives built in

Every retrofit is screened for Enbridge Gas and Save on Energy incentives before equipment is ordered.

FAQ

Frequently asked questions

When should a boiler or rooftop unit be replaced instead of repaired?

Replacement usually makes sense when equipment is near the end of its service life, repair costs are rising, parts are hard to find, or the unit is oversized. We compare the cost of keeping it running with the savings and incentives a high-efficiency replacement would bring.

Do HVAC retrofits qualify for incentives in Ontario?

Many do. Enbridge Gas offers incentives for measures that save natural gas, and Save on Energy offers incentives for measures that save electricity. Most programs require pre-approval before equipment is purchased, so we screen your project early.

Can you work with our existing mechanical contractor?

Yes. We act on the owner's side and work alongside your contractor, helping define scope, review pricing and confirm the work is completed and commissioned properly.

Which areas do you serve?

We are based in Brantford and serve Brant County, Hamilton, Haldimand, Norfolk and the rest of Ontario.
