Install, repair, maintain: HVAC in West Shore, Ontario
Almost everything we do falls into three categories, and they are different kinds of work with different aims. Knowing which one you need makes the conversation shorter. Metropolitan Heating and Air Conditioning serves West Shore from our shop on Venture Drive in Scarborough, and has worked on all makes and models since 1979.

Repair: work backwards from the symptom
A repair starts with a fault that already exists. The job is to identify which component produced the behaviour you are seeing, and the method is elimination rather than inspection.
We start from the symptom you describe and work outward through the components capable of causing it: static pressure and airflow, the thermostat and its wiring, electrical measurements at the contactor and capacitor, refrigerant pressures and superheat on cooling equipment, combustion and the safety chain on heating equipment, the condensate path, and the condition of the coils or heat exchanger.
You get the diagnosis before any work begins — what failed, what correcting it involves, and whether anything adjacent is close enough to failure to be worth doing on the same visit. If a repair does not stack up against the age and condition of the equipment, we will say so rather than sell it to you. See HVAC repair.
Maintenance: work done while nothing is wrong
Maintenance is the opposite exercise. Nothing has failed, and the point is to keep it that way by correcting drift before it becomes a fault.
Three things are actually happening during a tune-up. Cleaning: burners, flame sensor, blower wheel, condenser and evaporator coils, condensate drain — all of them lose performance to accumulation, and all of it is reversible. Verification against specification: gas pressure, temperature rise, refrigerant charge, thermostat calibration and cycle behaviour get measured against what the manufacturer specified rather than accepted as found. And safety inspection: heat exchanger integrity, flue condition, electrical connections, limit and rollout switches. That last category cannot be assessed from the thermostat, which is the main argument for doing it at all.
There is a warranty dimension too: most manufacturer warranties on equipment require documented annual servicing, so a skipped year can be the reason a claim is refused later. Arrange it through our maintenance plans or book a single visit as HVAC maintenance.
Installation: most of the work happens before the box arrives
Installation is a design job that ends in a physical one. The decisions that determine how the system performs for the next fifteen years are made before anything is unpacked.
Sizing comes from a load calculation — the volume and layout of the house, insulation levels, window area and orientation, and air leakage — not from the capacity of the unit being removed. Matching the old unit reproduces whatever error was there originally. Oversizing in particular causes short cycles, wider temperature swings and poor moisture removal in summer, because the equipment satisfies the thermostat before it has run long enough to do the rest of its job.
Then the duct system has to be assessed, because new equipment inherits it. A blower that cannot get its rated airflow through undersized trunks or an inadequate return will underperform regardless of what is on the data plate. Electrical supply, venting, condensate routing and line-set condition are all checked at the same time.
Commissioning is what separates a good installation from a poor one: charge verified against superheat and subcooling, airflow measured, temperature rise confirmed, gas pressure set, controls configured for the actual equipment, and every mode run through before we leave. See HVAC installation and replacement.
How the three feed each other
They are not independent. A system installed without commissioning starts out of specification, so maintenance spends its time correcting an installation error rather than reversing wear. A system never maintained accumulates the small drifts that eventually present as repairs. And repair history is a strong input into a replacement decision — three significant repairs across three seasons is a different situation from one failure on a system in its eighth year.
Which one you are probably asking for
If something is not working now, it is a repair. If everything is working and the season is turning, it is maintenance — and the shoulder season is when to book it, because a fault found then is a scheduled repair rather than a failure under load. If the equipment is old, the repair is major, or the system has never been comfortable, it is worth pricing installation beside the repair and comparing the two honestly. Financing is available through Vista.
