What Our Customers Are Saying
Highly recommend Murdoch and his team, we had an evap system removed and a ducted system installed which was life changing. Murdoch was always fast and efficient in communicating and answered all my questions, His team are super friendly and professional we could not be happier thank you again
Sinead Harrison
Very professional team, very responsive and they have an app for communications on your job. I think the air con now works better than when first installed!
Grant Smillie
I highly recommend MJM Mech Services.
I have had two very recent opportunities to work with MJM Mech Services, One to replace my domestic air conditioner and the other opportunity was servicing and carrying out repairs on our commercial property air conditioner.
Glen Campbell
Murdoch‘s team have helped us on short notice once before, but our experience this time was outstanding. He was able to fit us in between clients on short notice on an already busy day. He was able to advise us on a path forward with a difficult aircon install to work around time sensitive major renovations. The result was better than we had originally hoped for and under budget. It’s worth mentioning that I don’t know Murdoch personally but we will certainly be calling on him and his team if we need assistance with our air cons again.
Peter Willems
I recently had a Ducted AC system installed and a Evaporative Unit decommissioned and removed by Murdoch and his team from MJM Mech Services. This also included the replacement for the roof sheets where the Evaporative was once mounted. I am glad to say that I made the correct choice by using Murdoch and his Team. They were professional, meticulous, well prepared, friendly and engaging throughout the whole installation. Murdoch and his team made time to answer all my doubts and queries. They completed the entire scope with care and cleaned up when they were done. I recommend and endorse their good work. Well done Murdoch to you and your team; a Big Thank you.

FAQs
Common questions about how we work and what to expect.
Is this really free?
Yes. The initial assessment is completely free and comes with no obligation to move forward.
Do you do both residential and commercial work?
Yes - we’re fully equipped for both.
Do you offer emergency HVAC repairs?
Yes, we provide fast and reliable breakdown services for both residential and commercial clients.
Will you try to sell me on the call?
No. The goal of the call is to understand your situation and provide clarity. If we can help, we’ll explain how. If not, we’ll tell you honestly.
How often should systems be serviced?
Ideally, your HVAC system should be serviced at least once a year — twice if you use it heavily during both summer and winter. Regular servicing keeps it energy-efficient, prevents costly repairs, and ensures reliable performance all season long.
Are you licensed?
Absolutely. All work meets Australian standards.
