Commercial heating and cooling services

We offer a range of specialist services for a variety of commercial businesses, including schools, offices, warehouses, factories and restaurants. Our fast and efficient customised heating and cooling solutions keep your spaces comfortable year-round. Outstanding preventative and emergency maintenance keeps your system running smoothly.

Our approach

As a family-run business, we pride ourselves on our outstanding customer service. That means quotes when you need them, technical details in plain language and fast response times for faults or repairs.

While other heating and cooling companies use various contractors to complete different parts of their installations and maintenance, we never do. Our in-house teams run your project from end to end, which means consistent workmanship and a project that tracks on time and within budget. 

When it comes to energy efficiency, we’re equipped with the experience, knowledge and tools to reduce your energy consumption and operating costs. There’s often no need to replace your entire system. We can improve efficiency in more cost-effective ways, such as through controls upgrades, duct modifications, refrigerant replacement and economy air integration. 

‘I have used 21 Celsius on numerous occasions for several air-conditioning installations as well as gas heating replacements. They have great knowledge of both refrigerated and gas systems, are reliable and their work is top quality.’
