These are just some of the responses you can expect to hear from us at ACERair. We’re a ‘can do’ air-conditioning business (and if we can’t, we’ll let you know without giving you the run-around). We approach every job with the same attitude – to achieve the best outcome for the client – whether it’s a complete commercial fit-out or small residential repair. It’s about attention to detail, quality products, and the expertise to recognise the most cost-effective solution.

How we started.

Lee Wiseman began ACERair (AcerTech in those days) in 2010. In essence, he was a subcontractor (for some pretty big companies) and built his reputation by doing jobs others wouldn’t go near. Lee knew his stuff – refrigeration, electrical, controls and sheet metal – thrived on challenges and produced the goods. He was also likeable and dependable. Pretty soon, ACERair was getting more repeat business and more referrals. It needed more Lees.

And so that’s what happened. Lee employed people he knew were on the same page as him – had a positive attitude, were good at problem solving, and who were also likeable and dependable (which we are).

Where we are today.

Basically, we do all kinds of work in and around air-conditioning. Lee is still an integral part of ACERair, but we’re now a team of people, with greater expertise and ability. All of us are committed to providing the best air-conditioning solutions for our clients. And, of course, we have the required qualifications and certifications.

Our business is divided into two categories:

Commercial – design and construction, fit outs, maintenance and repairs

Residential – new and replacement installations, maintenance and repairs

We’re airflow geniuses, working out the most energy efficient ways to control climate, now and into the future. We’re always ready to take on a new challenge – non-standard is becoming standard for us.

How we work for you.

All of us at ACERair are hands on, dealing directly with clients. If we can’t speak to you straight away, we make sure we get back to you; no one is fobbed off or forgotten about. Basically, we start as we mean to go on, and communication is very important to us.

We’re available 24/7 for commercial clients and business hours weekdays for residential clients.

We offer free, onsite consultations, so that we fully understand the job, and the most cost efficient way of moving forward. We are professional, committed and approachable – it’s why we’re getting more referrals, why we’re winning more business, and why we’re growing.

We would be happy to speak to you about anything air-conditioning. Thanks for taking the time to read about us.
