Frequently Asked Questions
We believe a strong partnership starts with clear, honest answers about any hvac problems. If your question isn’t answered below, our team is always ready to help.
How much does an emergency air conditioning repair cost?
We provide a clear, fixed-price quote after our initial on-site diagnosis. The quote includes a standard call-out fee plus the cost of parts and labour. There are no hidden fees, and you approve the full cost before any work begins on the air conditioning unit.
Can you service my specific commercial air conditioning system?
Our extensive network includes licensed specialists for all major industrial air conditioning brands. We can check refrigerant levels and diagnose compressor issues. From rooftop unit repair to complex Daikin systems and Temperzone systems, we match the technician’s expertise to your system to ensure a correct and lasting repair.
How quickly can you dispatch an air conditioning technician to my site in Melbourne?
For urgent breakdowns, our goal is always same-day dispatch. Our operations team begins coordinating a response within minutes of your call and will provide a clear ETA from the start. We are equipped to handle after-hours emergencies for your air conditioning across Greater Melbourne.
What do you need from me to get started?
Just one phone call. We will ask for your site address, contact details, and a brief description of the air conditioning problem. From there, we handle the coordination. The only other thing we need is for you to provide site access for our technician.
Am I locked into a contract after one service call?
No. Our emergency repair services are provided on a job-by-job basis. If you are interested in ongoing proactive hvac maintenance, we can discuss our preventative plans under a separate service agreement for your air conditioning.
What if the problem returns after your repair?
We stand by our work with a comprehensive workmanship guarantee. If an issue returns due to a fault in our repair, we will come back and deliver a root cause fix at no additional cost to you. Our troubleshooting is thorough. Your peace of mind is our priority.
How are you different from calling an HVAC company directly?
As a facility management partner, our role is to provide a complete air conditioning solution. We handle the coordination of our pre-vetted specialists and manage the entire process from safety paperwork to final invoicing. This provides workload simplification and a more streamlined experience for you.
What are your service hours for after-hours emergencies?
Our standard office hours are Monday to Friday, 8am to 5pm. However, we monitor our phone lines and emails 24/7 to ensure we can respond to urgent after-hours emergencies and critical air conditioning breakdowns. A faulty thermostat can happen at any time.
