In a climate like ours in Mackay and the Whitsundays, a reliable, efficient air-conditioning system is essential for comfort at home and productivity at work. We supply, install, service and repair split system, ducted and cassette systems — including trusted brands like Panasonic.
At JSR Electrical & Air-Conditioning, we specialise in professional air-conditioning installations for both residential and commercial properties. We work with trusted brands like Panasonic and other leading models to make sure you get the right system for your space and your budget.
Our qualified technicians are also here for all your air-conditioning repair needs. We offer timely emergency repairs as well as preventative maintenance to keep your system running optimally. We can diagnose any issue, from a simple filter change through to more complex electrical problems — then give you a clear quote to either repair or replace the unit.
Our team receives ongoing training to stay up to date with the latest fault-finding techniques across a wide range of systems. Whether you're installing new or servicing existing, we understand the unique challenges our climate presents and can recommend the best solution for your needs.
Regular servicing and cleaning are key to ensuring your system runs smoothly and efficiently. The benefits include:
By removing built-up dirt and debris we ensure unrestricted airflow, which reduces strain on your unit and helps it run more efficiently.
A clean, well-maintained system uses less energy — helping you manage your power bills while enjoying better cooling performance.
Regular maintenance is the best way to extend the life of your air-conditioning unit and avoid costly breakdowns.
Cleaning and disinfecting your unit helps protect against airborne allergens and bacteria — important through our humid wet season.
Quality Panasonic highwall inverter split systems from 2.5kW through to 8.0kW — in reverse cycle (heating & cooling) or cooling only. Not sure which suits your room? We'll size it for you.
Prices vary by system size and installation requirements — every quote is free, fixed and includes the install. Other brands and sizes available on request.
When a single split system won't cut it, ducted and cassette systems cool the whole property evenly and discreetly. Ducted systems hide away in the roof space with outlets in each room, while ceiling cassettes suit open-plan areas, shops and offices where wall space is limited.
Cool only the rooms you're using and keep running costs down.
Cassettes suit shops, offices and open-plan Mackay workspaces.
We handle the full design, supply and install — one team, start to finish.
JSR Electrical offers post-purchase support and warranty for Panasonic air conditioners and Red Smoke Alarms — so if anything needs attention after installation, you're dealing with the same local team that fitted it.
A rough starting point for Mackay conditions. Ceiling height, insulation, window size and sun exposure all shift these figures — we'll confirm the right capacity on site.
| Room size | Typical space | Recommended capacity |
|---|---|---|
| Up to 20m² | Bedroom, study, small office | 2.5kW |
| 20–30m² | Large bedroom, small lounge | 3.5kW |
| 30–45m² | Lounge room, open living | 5.0kW |
| 45–60m² | Large open-plan living | 6.0 – 7.1kW |
| 60m² and above | Very large or high-ceiling areas | 8.0kW+ or ducted |
In the tropics an undersized unit runs constantly, costs more and wears out faster. Sizing up slightly is usually cheaper to run than an overworked small unit.

Filter and coil cleaning to combat the mould and dust our humid wet season encourages.
With long, humid summers and a serious wet season, Mackay air conditioners work harder than almost anywhere in the country. An undersized unit will struggle, run up your power bill and wear out early. We size every system to your space and our climate, install it for efficiency, and service it to fight the mould and salt-air corrosion that come with living near the northern beaches.

In many cases, yes. During the hotter months we prioritise breakdowns and aim to get your cooling back as fast as possible across Mackay and surrounding suburbs.
We recommend at least once a year, ideally before summer. Our humid wet season encourages mould and dust build-up in filters and coils, so regular cleaning keeps the air healthy and the system efficient.
Yes. We offer Brighte payment plans and Afterpay so you can have a new system installed now and pay it off in flexible instalments.
We do. We design, supply and install whole-home ducted systems for even comfort throughout the house, ceiling cassettes for open-plan and commercial spaces, as well as split systems for individual rooms.
We work with trusted brands like Panasonic and other leading models, so you get a system suited to your space and budget. Our Panasonic highwall inverter range runs from 2.5kW up to 8.0kW in both reverse cycle and cooling only — and we can source other brands on request.
Cooling only units cool, while reverse cycle units both cool and heat. In Mackay's climate cooling does most of the work, but reverse cycle is handy for the cooler nights through winter and usually only costs a little more.
Often, yes. We diagnose any issue — from a simple filter change to more complex electrical faults — then assess the situation and give you a clear quote to either repair or replace the unit, so you can make the call on value.
