## Common York Rooftop Unit Problems

York rooftop units are everywhere on older GTA plazas and industrial buildings, especially in Scarborough, Brampton and Mississauga. Many of the **York Sunline** units we see were installed in the 1990s and 2000s and are now at or past end of life: rusted base rails, crumbling coil fins, repeat compressor failures and refrigerant that is no longer made.

Newer **York Predator** and **York Sun Choice** units bring their own calls: controls faults, sensors, economizer issues and the usual capacitors and contactors. We read the control board diagnostics first, then work through electrical, refrigerant and airflow.

## York Models We Sell and Service

### York Sunline

The legacy workhorse. Many are candidates for phased replacement. When a Sunline needs a second compressor or has an R-22 leak, the written comparison usually favours replacement.

### York Predator

A common replacement for legacy York footprints, available in a wide tonnage range. We install Predator units on in-house **curb adapters** so the swap needs no new roof opening.

### York Sun Choice

York's packaged line for light commercial applications. Used on plazas and small offices.

### York YK chillers

Part of **Johnson Controls**, York YK centrifugal chillers are serviced by our CRE-ticketed crew. See 

commercial chiller service

[/commercial-chiller-service-toronto/ →](/commercial-chiller-service-toronto/)

.

## Legacy York Replacement Planning

Owners with roofs full of aging Sunline units are better served by a plan than a series of emergencies. We survey every unit, rank by condition, refrigerant and risk, and build a two- or three-season replacement schedule with Save on Energy filed for each phase. This approach suits Golden Mile buildings in 

Scarborough

 and older plazas across the GTA. See

Client Records

## What Clients Say About Our York RTUs

> "We have eleven old units across two Scarborough buildings. They ranked every one by condition and gave us a three-season replacement plan with rebate-net prices."

LPLinda P.Asset manager, Golden Mile

> "A 20-ton unit on our Scarborough warehouse needed a crane and a structural check. Permits, lift and startup were done on the dates promised."

RPRaj P.Facility manager, Scarborough

> "Three RTUs on our Junction retail building replaced for $46,800, exactly the number on the quote. Curb adapters fabricated in-house so the roofer was not needed."

OHOmar H.Landlord, The Junction

> "A new tenant needed more cooling than the old unit could give. They did a load calculation, set a new RTU on a new curb and had it commissioned before the tenant moved in."

SVStephanie V.Leasing manager, Vaughan

> "Eddy current results showed only one bundle needed retubing. That saved us from replacing a chiller that had another ten years in it."

MOMartin O.Chief engineer, North York office
