Our Services
Our Services
MJM Mech Services delivers professional heating, ventilation, and air conditioning solutions for homes, businesses, and commercial properties across Perth, the Wheatbelt, and the Perth-to-Kalgoorlie corridor. As ARC-authorised HVAC contractors (Authorisation No: AU43709), every installation, repair, and maintenance job we complete meets Australian regulatory standards.
Whether you need a new split system for your home, a full ducted solution for a commercial fit-out, or emergency breakdown support, our experienced technicians handle it from start to finish.
Air Conditioning Installation
We supply and install a full range of air conditioning systems to suit Perth’s climate:
- Wall-mounted split systems — ideal for single rooms, additions, and rentals. Quiet operation, energy-efficient, and fast to install.
- Ducted reverse cycle units — whole-home heating and cooling through a single system. We handle ductwork design, zoning, and commissioning.
- Cassette air conditioners — ceiling-mounted units suited to offices, retail spaces, and open-plan commercial areas.
- Evaporative cooling — a cost-effective option for dry Perth summers, delivering fresh airflow at a fraction of refrigerative running costs.
Every installation includes a site assessment, system sizing calculations, and a full walkthrough on handover so you know exactly how your new system operates.
Emergency Breakdown Service
When your air conditioner or heating system fails, comfort and safety are at stake — especially during Perth’s peak summer heat or cold winter nights. Our breakdown service covers both residential and commercial clients with fast-response callouts across our service areas.
Our technicians carry common replacement parts and diagnostic equipment to resolve most faults on the first visit, minimising downtime for your home or business.
Scheduled Maintenance & Repairs
Regular HVAC maintenance prevents costly breakdowns, reduces energy consumption, and extends the life of your system. Our maintenance service includes filter cleaning and replacement, refrigerant level checks, electrical connection inspections, ductwork assessments, and thermostat calibration.
We recommend servicing your system at least once a year — or twice yearly if you rely on it through both summer and winter. Businesses with compliance obligations (such as childcare centres and strata properties) benefit from our scheduled maintenance plans with documented service records.
Real Estate & Commercial Projects
We work with property developers, builders, strata managers, and real estate agents on HVAC projects for new builds, renovations, and ongoing property management. Our real estate services include:
- Childcare centre HVAC — compliant system design and installation meeting strict ventilation and temperature regulations.
- Strata properties — coordinated installations and maintenance across multi-unit developments.
- New builds — end-to-end HVAC design, supply, and installation integrated with your build timeline.
- Property management support — pre-sale and pre-lease inspections, system upgrades, and tenant-ready installations.
