Questions about our cleaning services, how often to service your AC, and what to expect from a visit.
In Darwin's tropical climate, we recommend a professional AC clean at least once per year — ideally before the build-up season when temperatures start rising. If your unit runs throughout the dry season as well, twice-yearly cleaning is a sensible approach. Commercial systems under heavy daily use may benefit from more frequent servicing.
A general clean covers the everyday essentials: air filter cleaning, indoor unit surface cleaning, drain inspection, and a cooling performance check. It's ideal for units that are serviced regularly. A deep clean goes further — it includes the evaporator coil, blower fan assembly, and the outdoor unit where required. If your system hasn't been serviced in a while, or you're noticing reduced performance or musty smells, a deep clean is likely the right choice.
Yes. We work with all major residential and commercial AC brands, including Daikin, Mitsubishi Electric, Fujitsu, Panasonic, LG, Samsung, Carrier, and many others. If you're not sure whether we can help with your specific unit, give us a call and we'll let you know.
A general clean typically takes around 45 minutes to 1.5 hours per unit, depending on the size of the system and how long since its last service. A deep clean naturally takes longer. We'll give you a realistic time estimate when we confirm your booking.
Yes, we ask that an adult be present during the service. This allows us to access the areas we need and to brief you on the outcome once we're done. If you have any concerns about timing, just let us know when you book and we'll try to accommodate you.
We take care to protect your property during every service. We use appropriate protection and clean up the work area before we leave. Our goal is to leave your space as we found it — tidy and undisturbed.
Questions about diagnosing faults, understanding your repair options, and what we look for during an inspection.
Unusual sounds are a sign that something isn't right. Rattling can indicate loose panels or debris. Grinding or squealing often points to a motor or bearing issue. Hissing might suggest a refrigerant concern. It's best not to ignore these sounds — contact MECHCOOL and we'll arrange an inspection before a minor issue becomes a major fault.
Water leaks from the indoor unit are most commonly caused by a blocked condensate drain line. When the drain can't flow freely, water backs up and spills from the unit. It can also be caused by a frozen evaporator coil that thaws and overflows the drain tray. Both issues are worth addressing promptly to avoid water damage. Our technicians will inspect and clear the cause.
There are several possible causes: a dirty evaporator coil reducing heat transfer, a refrigerant issue, a failing compressor, or a blocked outdoor unit. Sometimes it can also be as straightforward as incorrect settings. We'll run a thorough inspection to determine exactly what's causing the problem and advise you honestly on the best solution.
We diagnose and address a range of electrical faults including capacitor issues, control board problems, faulty wiring, and more. For faults that require licensed electrical work beyond our scope, we'll let you know and recommend the appropriate next step.
Absolutely. We always explain our findings and the recommended repair before proceeding. You'll know what's involved and what it will cost before any work begins. We won't carry out repairs without your approval.
Questions about installing a new AC unit, relocating an existing one, and what to expect from the process.
We install all major split system brands. If you've already purchased a unit, we can install it for you. If you're still deciding, we can discuss what size and type would suit your space.
Yes, AC relocation is one of our services. We safely disconnect the unit at the current location and reinstall it at the new one. This is a common request when people are moving house or rearranging a room. Contact us with details of both locations and we'll advise on what's involved.
Room size, ceiling height, sun exposure, and insulation all affect which capacity unit is suitable. When you contact us, we'll ask about your space and guide you on the right size. Undersized units struggle to cool effectively; oversized units can cycle on and off too frequently — getting it right matters.
