Rooftop Units

Installation, Maintenance, and Service

Rooftop Units or RTU’s

Heating and Cooling Solutions

Rooftop Units (RTU’s) are a common heating and cooling solution for large commercial properties. While the base building might operate with the use of boilers and chillers, tenanted spaces can benefit from lower costs and quieter operation of these smaller pieces of equipment. The evolution of building comfort has not only changed the way buildings are designed, it has changed the size of equipment we use too!

Not surprisingly, developers want to ensure most of the real estate in their commercial building can be leased or purchased. That means there is less room within the building to house large pieces of equipment. Instead, the installation of Roof Top Units keeps an attractive, organized appearance. Not only that, but energy management is also easily attained. Each unit can be considered a ‘zone’ which has set operating temperatures based on the occupancy of the space.

Packaged Units

Coils, Compressors, And Fans

That is also why Rooftop Units are also know as Packaged Units. This particular piece of equipment has its coils, compressors and fans all included. A cost effective and space conscious solution, there is no wonder why these units have become the norm for small commercial buildings.

Regardless of whether you have a new building, or you are upgrading equipment on an existing building, Caon can supply and install your Rooftop Units. Our experience with commercial installations makes us one of Calgary’s most reputable HVAC companies. We recognize the small details that allow for a seamless execution from quoting to commissioning and everything in between.

Rooftop Unit Maintenance

A Crucial Element

Just like any other piece of equipment, Roof Top Unit Maintenance involves checking the many moving parts that make it perform efficiently. Maintaining these parts is crucial to the longevity of your unit.

We document operating characteristics and verify them against manufacturers specifications. Keeping a record proves valuable if a failure is to arise. Service does not just stop at checking HVAC components. Tightening connections and lubrication is essential to optimize performance. If any issues are found that should be addressed, we provide a quote for the repair.

Servicing should be done at least twice a year, during the heating and cooling seasons. Depending on the size of your building you may want to include additional inspections and filter changes. Manufacturers honour their warranty based on proper maintenance. Equipment that has not been properly serviced or has repairs documented may have a hard time claiming on their warranty.

If you’re interested in an HVAC maintenance program, we can customize your service based on the type of equipment at each property and its age. Our approach is simple, we provide leading-edge training and state of the art technology to empower technicians with resources they need, when they need it.
