Commercial · Burlington, OntarioCommercial HVAC in Burlington
Commercial HVAC in Burlington is mostly rooftop work: packaged gas-electric units on plazas, offices and industrial bays, plus split systems, make-up air and exhaust in restaurants. ZK Mechanical repairs, maintains and replaces all of it from 4145 North Service Road, in the QEW corridor where much of that equipment sits. The working rule is to repair belts, motors, contactors and controls, and to plan a replacement once a unit past 15 years needs a compressor or a heat exchanger.
Rooftop units, split systems and maintenance for Burlington plazas, offices and industrial units
Burlington's commercial buildings sort into three groups, and each has its own equipment. Single-storey plazas along Plains Road, Guelph Line and Appleby Line typically carry one 3-to-10-ton rooftop unit per tenant. Industrial and flex units along the QEW and the North and South Service Roads pair a small rooftop unit over the front office with gas unit heaters in the bay. Downtown restaurants and shops around Brant Street and Lakeshore Road add kitchen exhaust and make-up air to the mix.
What fails follows the exposure. A roof beside the QEW takes road salt and grit in winter and wind off Lake Ontario all year, so cabinet panels rust, condenser fins clog and filters load faster than the same unit would in a sheltered office park. The repeat repairs are belts and blower bearings, contactors and capacitors, condenser fan motors, igniters and flame sensors on the gas section, and plugged condensate pans that show up as a stained ceiling tile. The expensive quiet one is the economizer: an actuator that fails with the outdoor damper open makes the gas section run all January while the space stays comfortable and nobody calls.
Commercial equipment brings its own paperwork. Gas work on a rooftop unit, a unit heater or a make-up air unit is done by TSSA-licensed technicians under CSA B149.1, refrigerant work by technicians holding an ODP card, and electrical connections under the ESA. Three-phase power from Burlington Hydro means a replacement has to match the building's voltage, commonly 208 or 575 volts, and ordering against the nameplate instead of the tonnage alone avoids a unit that arrives and cannot be connected. Where a replacement changes the curb, the weight on the roof or the duct layout, we confirm with the City of Burlington Building Department whether a permit applies before the crane is booked.
When you call, the first question is whether the space is down or just uncomfortable, because a restaurant with no cooling on a Friday is scheduled differently from a filter complaint. A site visit produces a written report per unit with the model, serial, age, what has failed and what is next, which a property manager can forward to an owner as is. From there it is a repair quote, a maintenance contract priced per unit, or a replacement plan, and commercial work is always priced per site in writing. The commercial HVAC page has the full scope, rooftop unit repair in Burlington covers RTU faults in detail, and you can request a site assessment.

Commercial in Burlington — FAQs
What does commercial HVAC service cost in Burlington?
It is priced per site, in writing, after an assessment: no flat rate fits both a 3-ton unit over a salon and a 10-ton unit over a restaurant. The drivers are the number of units, roof access, tonnage, parts availability and, for replacements, the curb adapter and crane. Night and weekend work carries no surcharge. Ask for the quote broken out per unit so each line can be approved separately.
How often should commercial HVAC filters be changed in Burlington?
It depends on the roof and the tenant, not the calendar. A unit near the QEW, or one over a salon, a restaurant or a dusty shop floor, loads filters far faster than one over a quiet office, and a loaded filter ices the coil in summer and trips the high limit in winter. We set the interval after the first two changes by how the filters look coming out. Commercial filter changes explains the program.
Do you repair commercial air conditioning in Burlington, or only rooftop units?
Both. Rooftop units are most of the work, but offices with a furnace-and-condenser split system, server rooms with a dedicated ductless unit and kitchens with a make-up air unit are all in scope. The summer faults are one family: capacitors, contactors, condenser fan motors, dirty coils and low refrigerant from a leak. Commercial air conditioning repair covers each of them.
Can the work be done without closing my business?
Usually. Repairs on the roof rarely need the space closed. A replacement needs a crane and a closed section of the parking lot under the lift, so it is booked for early morning or a day the tenant is shut, with the landlord told ahead of time. Because our rates do not change on weekends or holidays, a Sunday changeover costs what a Tuesday one would.
When should a Burlington landlord replace a unit instead of repairing it?
Plan the replacement when a unit past 15 years needs a compressor or a heat exchanger, or when the cabinet has rusted through at the base. Below that line, belts, motors, contactors, igniters and actuators are worth fixing. Older units on R-22 refrigerant are a special case, because a leak there is expensive to recharge. A per-unit condition report lets you budget the roof over several years instead of one emergency at a time.
