HVAC Contractor Services: Heating, Cooling, and Ventilation Done by the Right Crew
Main Drain Mechanical is a licensed mechanical contractor serving strata property managers, general contractors, and homeowners across the Lower Mainland, with a Red Seal plumber and Class B gas fitter on every job. HVAC work sits at the core of what the company handles, from air conditioning repair and ductwork service to heating equipment, ventilation repair, and thermostat installation, all carried out under the same credential and insurance standard the company brings to every trade call. If your building’s air handling is failing, a tenant suite has lost heat, or a renovation scope needs a licensed mechanical sub who won’t hold up the project, that’s exactly the situation this crew is built for.
When the System Fails and You’re Not Sure Who to Trust
The heat goes out on a cold January morning, or the cooling stops in the middle of a heat event, and the urgency of the situation pushes most people to call whoever picks up first, the kind of moment an emergency HVAC service exists for. That’s exactly when the wrong decision gets made. A technician who can’t trace the actual fault replaces the obvious part, charges for the visit, and leaves the root cause sitting there. Two weeks later the system locks out again, the building is back to square one, and now there’s a second invoice on top of the first.
The Work Behind an HVAC Contractor Call
Main Drain Mechanical handles the full range of heating, cooling, and ventilation work across the Lower Mainland; system diagnostics, heat pump installation, air handler repair, seasonal maintenance, duct and vent service, and thermostat work, as an HVAC contractor that holds Class B gas fitter licensing and Red Seal certification on every call. That credential combination matters because most HVAC problems touch gas, refrigerant, electrical, or all three, refrigerant leak repair on a cooling system requires the same accountability as gas work on a furnace, and a technician who isn’t licensed to work across those systems is guessing past the point where guessing is safe. Every job is backed by a 1-year workmanship warranty and a site left clean when the crew walks out.
How We Approach Each HVAC Service Call
A part doesn’t get swapped until the actual fault is confirmed, and a job isn’t finished because the system turned back on. These are the standards that decide whether a repair actually holds.
- A part doesn’t get replaced until the actual fault is traced. Swapping the obvious component without confirming it’s the real cause is how a customer ends up with a second invoice and the same problem still running underneath it.
- Safety controls, gas connections, and airflow get checked as a sequence, not in isolation. A failed motor and a restricted heat exchanger can look identical from the outside, and treating them as the same thing is how a gas pressure issue gets missed.
- Gas-fired equipment only gets touched under the licence the work actually requires. Furnaces, boilers, and make-up air units aren’t jobs for “close enough” credentials, because that’s the line between a repair that’s legal and one that isn’t.
- A finding gets explained before it gets acted on. A strata manager needs something to bring to council, a GC needs something for the schedule, and a homeowner needs to know what they’re approving – none of that happens after the fact. Residential HVAC service gets the same standard of explanation as a strata HVAC contractor call.
- The job isn’t finished because the system turned back on. It’s finished when it’s been run under the load it actually sees, because a repair that holds at startup and faults under demand is a callback that could have been caught on site.
- Documentation isn’t optional paperwork. Photos and service notes get produced on every job, because a record only exists if someone actually writes it down at the time, not from memory afterward.
How Will you Get the Work Done?
HVAC Services We Provide
From a single thermostat to a full mechanical room, this is everything that falls under the crew’s HVAC scope. Heating, cooling, airflow, and controls are treated as one system, not separate calls.
- Heating system installation, maintenance, and repair: furnaces and boilers, sized, serviced, and repaired to code.
- A/C system repair, maintenance, and installation, including air conditioning repair: cooling equipment kept running through the season it’s actually needed.
- HVAC repair service and HVAC system repair: diagnostics and fixes across the full mechanical system, not just one component.
- Heating system maintenance services: scheduled maintenance for residential furnaces and strata or commercial mechanical rooms, catching flame rod, heat exchanger, and condensate issues before they become a no-heat call.
- Ductless heating & A/C services, including heat pump installation: split systems and ductless units, installed and serviced by the same crew.
- HVAC duct & vent installation, repair, and cleaning: ductwork service and ventilation repair on the airflow side of the system, not just the equipment producing it.
- Thermostat installation and repair: the control point for the whole system, done right so the rest of the equipment isn’t compensating for a bad read.
What HVAC Work Costs
Repair pricing depends on what’s actually wrong. Common fixes – igniters, flame sensors, capacitors; typically run $150 to $400. Larger repairs, like an inducer motor, control board, or heat exchanger, run $500 to $1,200.
Installation costs depend on the equipment. A gas furnace typically runs $4,500 to $8,000 installed. A heat pump, heating and cooling in one system; runs $7,000 to $15,000, with FortisBC and CleanBC rebates often reducing that by several thousand.
Every quote follows a proper diagnostic, not a phone estimate – the fix and the cost depend on what’s actually found on site.
