Typical repair: Refrigerant leak detection and repair, valve replacement, coil cleaning, or component replacement.
Unit Won’t Turn On
Symptoms: Complete system failure, no response to remote or controls.
Common causes:
- Electrical supply issues (tripped breaker)
- Faulty thermostat or remote control
- Control board failure
- Blown fuses or damaged wiring
- Compressor overload protection activated
Typical repair: Electrical troubleshooting, control board replacement, or wiring repairs.
Unusual Noises
Symptoms: Grinding, squealing, rattling, or gurgling sounds during operation.
Common causes:
- Loose fan blades or mounting brackets
- Worn motor bearings
- Debris in outdoor unit
- Refrigerant flow restrictions
- Failing compressor
Typical repair: Component tightening, bearing replacement, debris removal, or motor replacement.
Water Leaking Indoors
Symptoms: Water dripping from indoor unit or pooling underneath.
Common causes:

- Disconnected drain line
- Frozen evaporator coil (then thawing)
- Improper installation angle
- Damaged drain pan
Typical repair: Drain cleaning, line reconnection, coil defrosting, or drain pan replacement.
Reduced Performance
Symptoms: Unit operates but doesn’t heat or cool effectively, higher running costs.
Common causes:
- Dirty filters restricting airflow
- Blocked outdoor coil
- Low refrigerant charge
- Failing compressor
- Dirty indoor coil
Typical repair: Filter replacement, coil cleaning, refrigerant recharge, or compressor replacement.
Ice Formation
Symptoms: Ice buildup on outdoor unit not defrosting, or indoor coil freezing.
Common causes:
- Defrost cycle malfunction

Customer receives repair documentation and maintenance recommendations.
Same-Day Service
Same-day repair service available for urgent situations during business hours (Monday-Friday 8am-5pm).
Emergency situations:
- Complete system failure during extreme weather

Repair vs Replacement Assessment
We provide honest assessment whether repair economically sensible:
Repair typically recommended when:
- Unit less than 8 years old
- Repair cost under 50% of replacement cost
- Single component failure
- No previous major repairs
- Unit generally reliable
Replacement may be recommended when:
- Unit over 12 years old
- Multiple component failures
- Repair cost exceeds 50% of replacement
- Frequent breakdowns
- Poor energy efficiency
- Government subsidy eligibility for new installation
We never recommend unnecessary replacements. If repair provides good value, we’ll recommend repair.

- Manufacturer warranty: We honour existing manufacturer warranties. No cost for warranty-covered repairs (parts and labour covered by manufacturer).
Warranty claims processed efficiently with manufacturer on customer’s behalf.
Emergency After-Hours Service
After-hours emergency repair available by arrangement for critical situations.
Critical situations:
- System failure during extreme cold or heat
- Safety hazards (electrical faults, refrigerant leaks)
- Water damage occurring
- Commercial applications requiring immediate restoration
After-hours service charged at premium rates. Non-critical repairs scheduled during business hours.
Preventive Maintenance
Regular maintenance reduces repair frequency and extends equipment life:
- Annual professional servicing
- Filter cleaning (monthly during peak use)
- Coil cleaning
- Refrigerant pressure verification
- Electrical connection inspection
Common Repair Costs
Typical repair cost ranges:
- Minor repairs (filter replacement, basic cleaning): $100-$200
- Moderate repairs (fan motor, capacitor, sensor): $250-$500
- Major repairs (compressor, reversing valve, control board): $500-$1,500
- Refrigerant leak detection and repair: $300-$800
Actual costs depend on specific fault, parts required, and labour time. Written quotes provided before work proceeds.
DIY Troubleshooting
Before calling for repair, check:
- Unit receiving power (check circuit breaker)
- Remote control batteries functional
- Filters not completely blocked
- Outdoor unit not obstructed
- Thermostat set correctly
- Mode selected correctly (heat vs cool)
Do not attempt:
