If you've never had your air conditioning or heating system professionally serviced, or if you've had a service that felt rushed and superficial, you might be wondering what a thorough job actually looks like.
At Alby Cool, we believe homeowners should know exactly what they're paying for. Here's a complete walkthrough of what a professional HVAC service call involves — and what to watch out for if you're comparing quotes.
Before the technician arrives
A professional technician will confirm the appointment, arrive within the agreed window, and come with the tools and parts needed for a standard service. They should introduce themselves, explain what they're going to do, and ask if you have any concerns or issues you've noticed with the system.
What a thorough service includes
1. Filter inspection and cleaning
The first and most visible step. Filters are removed, inspected for damage, and cleaned or replaced. This alone can improve system performance and air quality significantly if the filters haven't been maintained.
2. Indoor coil inspection and cleaning
The evaporator coil inside the indoor unit accumulates dust, mould, and bacteria over time. A thorough service includes inspecting and, where needed, cleaning the coil using appropriate cleaning agents. A dirty coil reduces efficiency and can circulate poor quality air through your home.
3. Outdoor unit inspection
The outdoor compressor unit is inspected for debris buildup, damage, corrosion, and adequate airflow clearance. The coils on the outdoor unit are also checked and cleaned if needed.
4. Refrigerant check
Refrigerant is the substance that makes your air conditioner cool. A licensed technician checks that the system has the correct refrigerant charge — too little significantly reduces efficiency and can damage the compressor over time. Only licensed technicians can legally handle refrigerants in Australia.
5. Electrical connections and components
All electrical connections are checked for tightness and signs of wear. Capacitors, contactors, and other electrical components are inspected. Loose or corroded connections are a common cause of system failures.
6. Condensate drain inspection
The condensate drain removes moisture extracted from the air during cooling. A blocked drain can cause water damage to your property. It's checked and cleared as part of a thorough service.
7. System performance test
Once the service is complete, the system is run in both heating and cooling mode (where applicable) and its performance is checked — temperature differential, airflow, noise levels, and thermostat accuracy.
8. Written report
A professional technician provides a summary of what was done, any issues found, and recommendations going forward. If a significant repair or replacement is needed, you should receive a clear explanation and a quote before any additional work is carried out.
What a rushed or poor service looks like
Unfortunately not every service call is thorough. Red flags include:
• In and out in under 20 minutes for a full system service
• No inspection of the outdoor unit
• No refrigerant check
• No written report or explanation of findings
• Being pressured to approve expensive repairs on the spot without a written quote
