Commercial · RTU & SplitHVAC that protects revenue
Commercial HVAC for Burlington, Oakville and Hamilton businesses covers rooftop units, splits, make-up air and exhaust — maintained on contract with a written condition report per unit, replaced on a planned crane day, and repaired at the same rates after hours as during them.
A commercial HVAC failure costs more than the invoice: a Kerr Village or downtown Burlington dining room at 30°C empties, a clinic cancels its afternoon, a Stoney Creek warehouse loses a shift. Commercial work is organized around that arithmetic — maintenance that catches the belt, contactor and seized economizer before the season, priority response when something quits anyway, and a straight capital plan for units past saving.
We service and replace rooftop units, commercial split systems, make-up air units for kitchens, exhaust fans and warehouse unit heaters. RTUs fail on a predictable list: belts and pulleys, blower bearings, contactors and capacitors, economizer dampers seized open in January, clogged condensate pans, and heat exchangers on units past 15 years. On the flat roofs of QEW-corridor plazas the cabinets take sun, lake wind and winter salt spray, so panels rust and linkages seize — half of what a maintenance visit is for.
RTU replacement is a crane day, run like one: curb measured, unit matched or an adapter fabricated, crane booked with the lot closed under the lift, gas and electrical reconnected by TSSA- and ESA-licensed trades, unit commissioned inside a business day. Most swaps here are 3-to-10-ton units on 1980s–2000s plazas — the property manager's RTU guide covers curbs, cranes and sign-offs, and what a rooftop unit costs covers the budget.
Property managers get per-suite billing, seasonal start-ups and shutdowns, a filter program on a calendar, and capital planning that says which units have years left and which are on borrowed time. Every visit produces a written per-unit report with photos, so the August complaint about suite 210 has an April paper trail. Commercial jobs are priced per site after an assessment — request one.
Call about your building when
- Tenants complain about the same suite every August and every January
- An RTU past 15 years just needed a compressor, a heat exchanger or its second refrigerant charge
- The kitchen door is hard to pull open — make-up air and exhaust are out of balance
- A lease, lender or insurer is asking for maintenance records that don't exist
- The space is changing use — retail to clinic, warehouse to gym — and the load changed with it
How it works
Each RTU, split and exhaust fan is tagged, photographed and condition-scored — age, refrigerant type, heat exchanger, economizer, belts, drains — so you see the building's real state, not a sales sheet.
A maintenance schedule with the filter program and seasonal visits, replacement quotes where needed, and a capital timeline for aging units. Maintenance contracts are priced per unit.
Contract clients go to the front of the emergency queue, nights and weekends included, with no after-hours premium — a Saturday-night cooling failure in a full dining room is billed like a Tuesday.
Brands: Carrier, Lennox, Trane, York, Daikin RTUs and splits — serviced and replaced.
Common questions
What does commercial HVAC maintenance include?
Per visit: filters on the program, belts checked and tensioned, blower bearings, contactors and capacitors tested, coils cleaned, condensate pans and drains cleared, economizer dampers and sensors exercised, refrigerant pressures logged — and on gas units, a fall combustion and heat exchanger inspection. Each unit gets a written condition report with photos.
RTU or split system for my space?
An RTU packages heating, cooling and ventilation in one rooftop cabinet and suits open-plan retail, warehouses and single-tenant buildings with roof capacity. Splits suit multi-room offices and clinics, and older Kerr Village or Westdale storefronts where roof structure or access rules out a curb. We assess the space instead of defaulting to what's up there now.
How disruptive is an RTU replacement?
One business day in almost all cases: crane in the morning, old unit off, new unit set on the existing or adapted curb, reconnected and commissioned by close. Expect the parking under the lift closed for the morning and gas to that unit off while the lines are remade. Multi-unit swaps are sequenced so the space never loses all heating or cooling at once.
Do you work after hours?
Yes. Replacements and heavy maintenance for tenant-facing spaces run overnight or on Sundays at the same rates, and multi-tenant work is coordinated through the property manager so tenants get notice. See restaurant HVAC and property management HVAC for the two most scheduling-sensitive cases.
Which commercial spaces do you serve?
Restaurants and commercial kitchens, retail plazas, offices, medical and dental clinics, schools and daycares, places of worship, and warehouses across Burlington, Oakville, Hamilton and the GTA. From the North Service Road shop, the QEW plazas and Hamilton's industrial east end are the closest runs. Each vertical has its own page under this one, with the equipment and pain points that go with it.
