Diagnose air conditioners that are not cooling correctly, are cycling unexpectedly or show unusual operating behaviour.
West Vancouver
We diagnose and repair AC systems throughout West Vancouver — Ambleside, Dundarave, British Properties, Caulfeild and Horseshoe Bay. West Vancouver's hillside and multi-level homes, larger floor plans and varied mechanical configurations mean repair work often involves access and distribution considerations beyond a standard flat-site call.
The system runs but room temperature doesn't drop to setpoint. Possible causes include a dirty coil, refrigerant issue, blocked filter, or a failing compressor. Diagnosis determines the actual cause.
Low airflow from vents may indicate a blocked filter, restricted ductwork, a failing blower, or duct damage. In multi-level West Vancouver homes, uneven cooling across floors often has a distribution cause separate from the equipment itself.
A system that starts and stops repeatedly — without completing a full cooling cycle — may be responding to a control fault, refrigerant issue, or an oversized system that's reaching setpoint too quickly on main floors while upper levels remain warm.
If the system doesn't respond to thermostat adjustments correctly, the issue may be the thermostat itself, wiring, or a communication fault between the thermostat and air handler. We test the full control circuit before replacing components.
Water around the air handler or ductless indoor unit often indicates a blocked condensate drain or a frozen coil that has thawed. We clear the drain and identify what caused the blockage or freeze condition.
Grinding, rattling, or squealing can indicate a failing motor or loose component. A system that won't start may have a tripped breaker, a blown fuse, or a failed capacitor or contactor — some of which are straightforward replacements.
If you suspect a refrigerant issue — reduced cooling despite clean filters, ice on the coil, or hissing sounds near the outdoor unit — do not attempt to add refrigerant or open the refrigerant circuit yourself. Refrigerant handling requires certification and specialized equipment. A licensed technician can perform a proper leak check and repair before any refrigerant is added.
Decision Guide
The right choice depends on the diagnosis, equipment age and what the repair actually costs relative to a new system.
If your AC needs replacement rather than repair, see our AC installation West Vancouver page or Central AC Installation for system overviews.
Common Questions
Yes. We diagnose and repair central air conditioning and ductless mini-split systems across West Vancouver — including Ambleside, Dundarave, British Properties, Caulfeild and Horseshoe Bay.
Common causes include a dirty air filter restricting airflow, a blocked or dirty condenser coil, a refrigerant issue reducing heat exchange, or a failing component like the compressor or expansion valve. Some of these are straightforward service items; others require diagnosis by a licensed technician. If the system runs but produces little cooling, have a technician assess it before the problem worsens.
The right call depends on the diagnosis, equipment age and repair cost relative to replacement. A newer system with a single failed component usually warrants repair. An older system requiring a major repair — compressor, coil, or refrigerant circuit — may be more cost-effective to replace, especially if it's approaching end-of-life or uses older refrigerant. We'll give you a straightforward assessment after diagnosis.
The component that needs repair or replacement, system type and age, refrigerant type, and whether the system is accessible all affect cost. A diagnostic visit establishes what's actually needed before any repair work begins.
Yes — we service central air conditioning systems alongside ductless mini-splits and heat pump cooling systems. If your central AC isn't performing correctly, we can diagnose and repair it.
We diagnose the actual cause before recommending any repair — no pressure toward unnecessary replacement.
