Split system supply, install and maintenance done properly — sized right, installed cleanly, servicing you can rely on.
Ultralec supplies, installs and services split system air conditioning across Cooroy, Pomona, Cooran, Noosa, Tewantin, Eumundi, Gympie and the wider Sunshine Coast. As a licensed electrical contractor and experienced air con installer, we handle the whole job — wall penetrations, indoor unit mounting, outdoor compressor location, electrical connection back to the switchboard, commissioning and testing — with one tradesperson, one warranty, one clean finish.
Queensland summers don't mess around. A well-sized, well-installed split system is the difference between a comfortable home and an expensive, underperforming box on the wall. We take the time to get both parts right.
We supply and install quality-brand split systems — the ones that actually hold up in our climate — sized correctly for your room and your home's layout. Whether you need a single-head system for a bedroom or a multi-head setup covering living, bedrooms and office, we size it with proper heat-load calculation rather than guesswork.
Installation includes: neat indoor unit placement (no sagging condensate lines), outdoor compressor on a solid bracket or pad in shade where possible, pipework through the wall penetration professionally sealed, dedicated isolator switch within sight of the unit, and a proper commissioning test before we hand over.
Undersized air con struggles on hot days and runs constantly — higher bills, shorter lifespan, more servicing. Oversized air con short-cycles, dehumidifies poorly, and costs more upfront and on power. We calculate actual heat load based on the room's size, insulation, orientation, windows and ceiling — then recommend a capacity that fits. It's a 15-minute conversation that saves you thousands over the life of the system.
Air con systems need regular servicing — especially in our climate where filters clog with pollen, dust and insect debris fast. A serviced system runs more efficiently, cools better, lasts longer and doesn't blow dust into your air. We offer scheduled servicing (annual or twice-yearly) covering:
If your older split system just "isn't cooling like it used to", a thorough coil clean often brings it back. Outdoor coils in particular get caked with fine dust and grass clippings over the years — restricting airflow, killing efficiency and eventually burning out the compressor. We do proper chemical coil cleans on both indoor and outdoor units.
We install quality brands suited to the Queensland climate — Mitsubishi Electric, Daikin, Panasonic, Fujitsu. We're brand-agnostic: we'll recommend what fits your budget and your needs, not what gives us the biggest margin.
Cooroy homes range from modern estate builds to older hinterland properties — every one has a different cooling challenge. Whether you're in the centre of town, on acreage off Myall Street, or out towards Ringtail Creek, we've installed systems that suit the local climate and the specific home.

Most single-head residential installs range from around $1,800 to $3,500 supplied and installed, depending on size, brand and installation complexity (back-to-back vs long pipe runs). We give fixed written quotes before we start.
Annually for most homes — twice a year if you run it hard year-round or live near the coast. Regular servicing keeps efficiency up and extends the life of the system.
We install quality brands — Mitsubishi Electric, Daikin, Panasonic, Fujitsu — which are proven in the Queensland climate and have local warranty support. We'll recommend what suits your budget and needs.
