AC Repair Across Burnaby

Serving Burnaby Neighbourhoods

We diagnose and repair AC and cooling systems throughout Burnaby — Metrotown, Brentwood, Capitol Hill, Deer Lake, Burnaby Heights, South Slope and surrounding areas. Burnaby's cooling systems are not uniform: central AC is common in older detached homes; ductless mini-splits appear frequently in newer condos and townhomes; some properties use a heat pump in cooling mode as their primary summer cooling source. Repair content addresses cooling performance, airflow, controls and system condition without assuming every home uses central AC — the actual system configuration matters for diagnosis.

Common AC Symptoms

Running But Not Cooling

The system operates but indoor temperature doesn't drop to setpoint. Common causes include a refrigerant issue reducing the system's cooling capacity, a dirty condenser coil preventing heat rejection outdoors, or a failed component in the refrigerant circuit. Symptom alone is not sufficient for diagnosis — the system needs to be evaluated to identify the actual cause.

Weak or Uneven Airflow

Low airflow in a central AC system often points to a dirty filter, a failing blower motor, or a duct restriction. Older Burnaby homes with original ductwork may have undersized return capacity that shows up as warm spots in certain rooms rather than a primary equipment fault. In ductless systems, weak airflow may indicate a dirty indoor coil or a fan assembly issue.

System Not Starting

An AC that won't start may have a tripped breaker, a failed capacitor or contactor, a control fault, or a locked-out compressor. Repeatedly resetting a tripped breaker without diagnosis can mask a deeper electrical fault — we test the circuit before recommending any component replacement.

Unexpected Cycling

Frequent short cycles — starting and stopping without completing a full cooling run — can indicate an oversized system reaching setpoint too quickly, a refrigerant pressure issue, or a control fault. In multi-level Burnaby homes, a thermostat located in a cooler area may reach setpoint while upper floors remain warm, creating apparent cycling behaviour that's actually a distribution issue.

Condensate or Water Concerns

Water pooling near the indoor air handler or dripping from a ductless unit usually indicates a blocked condensate drain line. When the drain is blocked, many systems shut down on a safety float switch rather than overflow — the system stops cooling without any obvious error. This is a common summer service call and typically straightforward to clear, though it can recur without addressing the root cause of the blockage.

Control Issues or Unusual Sounds

Thermostat and control faults can prevent the AC from responding to cooling calls, or cause erratic operation. Unusual sounds — rattling from the outdoor unit, squealing from the blower, banging on startup — each point to different causes. Rattling often suggests a loose fan blade or debris in the outdoor unit; grinding from a blower motor often indicates a bearing issue that will worsen if left running.

AC Problems Have Several Possible Causes

The symptom alone is not enough to determine the repair. A proper service visit evaluates the equipment, controls, airflow and distribution, and relevant system components before recommending repair or replacement. We do not diagnose refrigerant leaks from symptoms alone, and do not recommend component replacement without confirming the actual fault.

Refrigerant and Electrical Safety

Do not attempt to add refrigerant, open refrigerant lines, or bypass safety controls. Refrigerant handling requires certification and specialized equipment. If a breaker trips repeatedly after reset, stop resetting it — this can indicate a serious electrical fault requiring professional diagnosis. If you smell burning near any HVAC equipment, treat it as an electrical issue and have the circuit shut off before calling for service.

Repair or Replace?

The right path depends on the diagnosis, the system's age and condition, repair cost versus replacement cost, and your future HVAC plans.

Repair Often Makes Sense When

  • The system is fewer than 10–12 years old
  • The fault is a single component — capacitor, contactor, fan motor, control board
  • The compressor is confirmed healthy
  • The refrigerant type is not discontinued
  • The system has been maintained and otherwise performs well

Replacement May Be the Better Path When

  • The compressor has failed on an older system
  • There is a refrigerant circuit fault on a system using R-22 or another phased-out refrigerant
  • Repair cost approaches a meaningful portion of a new system's installed price
  • Recurring failures suggest broader decline
  • A heat pump would better serve both summer cooling and year-round comfort

If replacement is the better path, see our AC installation Burnaby page or Central AC Installation for an overview. If you're considering a heat pump as a cooling and heating upgrade, see heat pump installation Burnaby.

AC Repair FAQ — Burnaby

Yes. We diagnose and repair AC and cooling systems throughout Burnaby — Metrotown, Brentwood, Capitol Hill, Deer Lake, Burnaby Heights, South Slope and surrounding areas. Burnaby's cooling systems range from central AC in older detached homes to ductless mini-splits in condos and newer townhomes. Each type has distinct repair considerations, and we address the actual configuration rather than assuming a single system type.

An AC problem can have several causes, so the symptom alone is not enough to determine the repair. Common issues include a refrigerant problem reducing cooling capacity, a failed capacitor or contactor, a dirty condenser coil reducing heat rejection, a blower or fan motor fault, a control or thermostat fault, or a drainage blockage causing a safety shutdown. A proper service visit evaluates the equipment, controls, airflow and distribution before recommending repair or replacement.

Repair-versus-replacement depends on diagnosis, repair scope, equipment condition, reliability, compatibility and your future HVAC plans. A newer system with a single failed component usually makes sense to repair. An older system with a compressor failure or a refrigerant circuit fault using R-22 or another phased-out refrigerant may be more economical to replace. We give an honest assessment after diagnosis.

The specific fault and component involved, the system type and age, the refrigerant type, and site access all affect repair cost. A failed capacitor or relay is a straightforward repair. A compressor failure or refrigerant circuit fault is more involved and warrants a frank conversation about repair-versus-replacement. A diagnostic visit establishes the actual cause and scope before any repair work is quoted.

Helpful information includes the AC system brand, model and age if known, a description of the symptom (what the system is doing, when it started, any error codes or flashing lights), whether the outdoor unit is running, and whether you've noticed water or condensate around the indoor unit. Any recent filter changes or service history is useful context for the technician.
