Split System Installation · Dorrigo
FHC installs split system air conditioners across Dorrigo, on the Dorrigo Plateau at 731 metres elevation, where the dominant equipment stress is not salt but cold and damp. Dorrigo averages 2,034mm of annual rainfall — genuinely wetter than the coast and cooler year-round — which drives moisture ingress, drainage handling and heating capacity as the main installation considerations, all under Bellingen Shire Council planning controls.
Installing on the wet, cold Dorrigo Plateau
Dorrigo sits at 731 metres elevation on the Dorrigo Plateau, 64 km south-west of Coffs Harbour, with a population around 1,050 and dairy country as the dominant land use. The climate is meaningfully different from the coast: mean maximum 20.0°C, mean minimum 10.0°C, and 2,034mm annual rainfall — the wettest position in FHC's service area by a substantial margin. The plateau produces genuine winter cold and persistent damp rather than the humid subtropical warm-and-wet pattern of Coffs Harbour.
Installation priorities here are inverted from the coast. Reverse-cycle systems with real winter heating capacity are the sensible default rather than cooling-focused specifications — winter heating matters more than summer cooling for most of the year on the plateau. Outdoor-unit siting has to handle prolonged wet weather, so drainage away from the unit and shelter from direct rainfall onto electrical components are practical considerations that inland-Coffs installations rarely address. Older Dorrigo homes are commonly weatherboard on stumps, which affects both refrigerant line routing and outdoor-unit mounting. Consent falls under Bellingen Shire Council.
What FHC delivers on every split system installation
A split system installation covers the indoor head, the outdoor condenser, the refrigerant line set and drain that connect them, and the electrical circuit that feeds the condenser. FHC handles supply, installation, refrigerant charging, electrical connection, and full commissioning as one job under a single point of accountability, rather than splitting work across separate trades.
FHC installs Daikin, Mitsubishi Electric and Midea and services all major residential brands including Fujitsu, Panasonic, LG and Haier, specifying the system, capacity and mount position on the property during the quoting stage. All refrigerant work is completed by ARCtick-licensed technicians (RTA AU069269), which is a federal legal requirement in Australia. Installations are completed to the relevant Australian Standards and to manufacturer specifications.
Every install is commissioned through a full heating and cooling test cycle before the crew leaves the site. FHC registers the manufacturer warranty on your behalf, provides written documentation of the commissioning result, and applies a 12-month workmanship warranty on the installation work.

Frequently asked
Should Dorrigo installations prioritise heating capacity over cooling?
Yes. At 731 metres with mean minimum 10.0°C, Dorrigo winters are genuinely cold and heating capacity matters more than cooling capacity for most of the year. FHC specifies reverse-cycle systems sized primarily to the winter heating load rather than the summer cooling load, and confirms the specific unit maintains rated capacity at low ambient temperatures.
How does 2,034mm annual rainfall affect Dorrigo installations?
Outdoor-unit siting on the plateau has to account for prolonged wet weather — direct rainfall onto exposed electrical components accelerates corrosion, and standing water around the unit base drives drainage and mounting-corrosion issues. FHC positions outdoor units under natural or built shelter where possible and ensures drainage away from the unit base is properly graded during installation.
