We're Sydney's most trusted HVAC-R specialists.

Criticool Services has been keeping Sydney’s commercial spaces comfortable since 2012. What started as a one-man operation has grown into a trusted name in the HVAC-R industry. Our founder, an industry veteran, took a leap of faith by taking over a major contract from a retiring employer. After a brief pause to focus on family, we relaunched in 2022 with renewed energy and a sharp focus on quality service.

We’re in the business of keeping things cool – literally. From regular check-ups to emergency fixes and custom system designs, we’ve got all your HVAC-R needs covered. Our goal? To deliver top-notch solutions without breaking the bank.

We’re not just about fixing air conditioners. We’re problem solvers who look at the big picture. Got a water leak that’s damaged your ceiling? We’ll sort out the AC and coordinate the repair work too. It’s this all-in-one approach that sets us apart.

The heart of Criticool is our team. We’ve got decades of combined experience under our belts, from our skilled technicians to our efficient office staff. Everyone here shares the same goal: to keep our customers happy and their systems running smoothly.

We believe happy employees make for happy customers. That’s why we’ve built a workplace where teamwork thrives, ideas are shared, and everyone’s contribution is valued. It’s not just about work – it’s about creating an environment where people enjoy what they do.

While we call Sydney home, our reach extends to the Central Coast and Blue Mountains. Need help in Canberra or Queensland? We’ve got you covered with remote support.

At Criticool, we’re all about delivering what our customers need. Whether it’s a quick fix or a complete system overhaul, we’re committed to getting the job done right. When you choose Criticool, you’re choosing reliability, expertise, and service that goes above and beyond.
