Frequently Asked Questions
What size commercial air conditioning system does my Darwin business need?
System size depends on several factors, including building size, insulation, occupancy, equipment heat loads, and Darwin’s tropical climate. We carry out detailed load calculations to ensure your system is correctly sized for efficient operation without overworking or underperforming
How often should commercial HVAC systems be serviced in Darwin’s climate?
Darwin’s high humidity and long cooling season mean systems require more frequent maintenance than temperate climates. We generally recommend quarterly inspections and comprehensive annual servicing, though requirements vary depending on system type, usage, and environmental factors.
Can you service all brands of commercial air conditioning equipment?
Yes. Our technicians are trained to service all major commercial HVAC brands. We also have access to genuine parts and supplier networks across the Northern Territory, ensuring your system is repaired professionally and reliably.
What’s included in your emergency commercial air conditioning service?
Our 24/7 emergency service includes:
- Rapid response and fault diagnosis
- Temporary solutions where possible
- Priority scheduling for permanent repairs
- Mobile service and emergency parts to minimise downtime
Do you provide energy efficiency assessments for existing systems?
Absolutely. We offer comprehensive energy efficiency assessments, reviewing system performance, control settings, and operational practices. We provide recommendations to reduce running costs while maintaining comfort.
What warranties do you provide on installation and repairs?
We provide warranties on both workmanship and equipment. Terms vary depending on the system and manufacturer, and all coverage is clearly outlined in our proposals. Our ongoing maintenance programs also help ensure your warranties remain valid.
Can I troubleshoot my air conditioner before calling a technician?
Yes. Some common checks include:
- Filters: Remove and clean at least monthly.
- Remote settings: Ensure the correct temperature and mode are selected.
- Batteries: Replace remote batteries if flat.
- Outdoor unit: Check for obstructions blocking airflow.
- Timer lights or error codes: Flashing lights often indicate a fault; refer to the system manual or contact us for Daikin and Mitsubishi MHI assistance.
Do you offer on-site fault finding?
Yes. We provide 1-hour labour troubleshooting onsite, with extra time in 15-minute blocks if needed. Our service includes:
- Checking remotes and settings
- Clean-up after inspection
- Detailed before-and-after reports
- Quoting parts and gas separately if required
Why is my air conditioner crackling or spitting out ice?
This usually happens for one of two reasons: either there’s a gas shortage (often due to a leak that needs fixing) or the system is extremely dirty and clogged. In the latter case, a Deluxe Professional Service (deep clean) will restore performance and prevent further issues.
My AC is cold but not blowing air. What’s wrong?
If your air conditioner is producing cold air but no airflow, the issue is often with the scroll/barrel fan or clogged internal components. A professional cleaning service typically resolves this problem and ensures your system works efficiently.
My air conditioner won’t turn on. What should I do?
First, try using the “auto” on/off button under the indoor cover. If the receiver in the unit is faulty, the system can still run using this method until a technician replaces the part. For persistent issues, our team can quickly diagnose and repair the fault to get your system running reliably again.
