Aurum Fan Coil Replacement in Toronto & the GTA

Aurum retrofit units are built around a slide-in or drop-in chassis, engineered specifically to replace an aging fan coil without disturbing the surrounding wall, floor, or ceiling.

In practical terms:

• Existing piping, electrical connections, and the structural opening are reused wherever possible, reducing the scope of the replacement.
• Stainless steel chassis and drain pan construction improve durability and reduce the corrosion-related failures common in older units.
• Insulated chassis construction reduces vibration noise compared to many original 20- to 40-year-old fan coils.

This retrofit approach performs particularly well in Toronto and GTA condos and rental apartment towers, where suites are occupied and disruptive renovations are difficult to schedule around residents.

Toronto and GTA condos and apartment towers present specific challenges: occupied suites, limited service access, and fan coils that are often original to buildings built decades ago. Aurum’s retrofit approach was developed around these conditions.

The BTR Series is Aurum’s flagship retrofit solution and the unit Cozy Comfort Plus recommends most often for fan coil replacement projects in Toronto and the GTA. It’s engineered to replace outdated blow-through vertical fan coil units — the configuration found throughout a large share of the region’s condo and apartment towers.

Key characteristics:

• Slide-in chassis designed to fit the existing blow-through opening
• Stainless steel chassis and drain pan construction
• Insulated interior to reduce vibration noise
• Available in multiple capacities to suit different suite sizes

Because blow-through vertical units are so common across the GTA’s high-rise stock, BTR is typically the first configuration Cozy Comfort Plus evaluates during a fan coil replacement assessment.

Aurum BTR Series Fan Coil

Aurum’s most-installed retrofit solution, built to replace outdated blow-through vertical fan coils with minimal disruption to the suite.

The CFC Series replaces fan coils installed in a closet or other compact enclosure. Its drop-in chassis is designed for the tighter clearances typical of a closet installation.

Key characteristics:

• Drop-in chassis sized for closet and compact enclosure installations
• Stainless steel construction, matching the durability of the BTR Series
• Designed to reuse existing closet piping and connections wherever possible

This configuration is common in older GTA rental buildings and condos where the fan coil was built into a linen or utility closet rather than a standalone cabinet.

The DDR Series replaces ceiling-mounted or down-draft units, where air is discharged downward into the space rather than blown upward through the cabinet.

Key characteristics:

• Component-based chassis suited to down-draft, ceiling-mounted installations
• Preserves the original downward air-distribution path
• Same efficiency and durability upgrades as Aurum’s other series

Down-draft configurations appear less often than blow-through units in GTA buildings but are common in specific building eras and layouts.

Aurum DDR Series Fan Coil

The DTR Series replaces units where air is drawn through the coil before discharge — the reverse airflow arrangement from a blow-through unit.

Key characteristics:

• Drop-in chassis engineered for draw-through airflow configurations
• Matches the original air path, avoiding changes to supply and return connections
• Same stainless steel construction standard across the Aurum lineup

Confirming whether an existing unit is blow-through or draw-through is one of the first things Cozy Comfort Plus checks during a site assessment, since the two configurations require different Aurum series.

Aurum DTR Series Fan Coil

A like-for-like replacement for draw-through fan coil configurations, installed without disrupting the original airflow path.

Some buildings use a blow-through unit built into a wide, shallow cabinet rather than a standard vertical footprint. The MHR Series is purpose-built for this non-standard configuration.

Key characteristics:

• Wide-format chassis matched to shallow blow-through cabinets
• Same coil, blower, and drain pan standards as Aurum’s vertical series
• Suited to buildings where a standard vertical chassis won’t fit the existing opening

MHR is a more specialized fit than BTR, and is typically confirmed only after measuring the existing cabinet on-site.

Selecting the right series depends less on the building’s age and more on how the existing unit is physically configured.

Replacing Older Unilux Fan Coils & Air Handlers

Many fan coil units installed in Toronto and GTA condos and apartment buildings from the 1970s through the 1990s were originally manufactured by Unilux, a legacy fan coil and air handler brand. As these units age, parts and service support for the original equipment have become increasingly limited.

Aurum’s retrofit chassis are engineered to match the physical footprint and connections used across common blow-through, closet, down-draft, and draw-through configurations, which makes an Aurum retrofit a suitable option for many Unilux applications. That said, Unilux produced multiple models and configurations over several decades, and not every installation will be a direct match for a standard Aurum chassis.

Cozy Comfort Plus doesn’t assume compatibility with any legacy brand, including Unilux. We assess the existing unit’s configuration, dimensions, and connections on-site before confirming which Aurum series is the right fit — or identifying what modifications, if any, would be required.

Aurum Manufacturing is a Canadian company based in Vaughan, Ontario, specializing exclusively in replacement solutions for outdated fan coil systems. The company’s engineering approach draws on decades of hands-on mechanical experience in the high-rise HVAC industry, with a focus on designs that fit the building rather than requiring the building to be modified to fit new equipment.

Aurum retrofit units are manufactured with type-L copper tubing, aluminum fins, and stainless-steel construction, and undergo pressure testing before leaving the Vaughan facility. Because Aurum is manufactured locally in the GTA, Cozy Comfort Plus can typically access units and parts faster than with imported alternatives — an advantage when a building needs a fan coil replaced with minimal downtime.

An Aurum fan coil replacement upgrades the suite-level terminal unit — the equipment that delivers heating and cooling directly into each unit — without changing the building’s central plant, such as the boiler or chiller supplying hot and chilled water.

In most buildings, this means:

• Fan coil replacement addresses in-suite comfort, noise, and efficiency issues without requiring a central plant upgrade
• Central heating and cooling infrastructure typically remains unchanged
• Buildings often phase fan coil replacement floor by floor or suite by suite, independent of any central system planning

For buildings with both aging fan coils and aging central equipment, Cozy Comfort Plus can advise on how a fan coil replacement program fits into a broader capital planning timeline.

Cozy Comfort Plus installs Aurum fan coil retrofits across Toronto, North York, Vaughan, Richmond Hill, Mississauga, Etobicoke, Scarborough, and Markham. Every installation follows Ontario code requirements, with attention to piping connections, electrical work, and long-term serviceability.

For property managers and building owners comparing Aurum fan coil replacement options or planning a fan coil retrofit in Toronto, the right series typically depends on the existing configuration, suite capacity requirements, and building type.
