During the 21 June technical meeting, the SAIRAC Johannesburg centre were schooled in the importance of maintenance and showed some useful products to make this vital task less time consuming.

Before the technical talk, South African Institute of Refrigeration and Air Conditioning (SAIRAC) Johannesburg centre chairman, Jaco Pieterse, said a few words about the recent FRIGAIR expo, thanking the organisers and everyone involved in making it a success.

He then handed out certificates to people who had completed courses and spoke on the upcoming courses scheduled for the rest of the year. Pieterse also mentioned other upcoming centre events and highlighted the momentous ASHRAE chapter launch to happen on 27 July. He also welcomed some new members to the centre.

The speaker of the night was Douglas Scott of HCM Contractors who gave a brief history of the company, explaining how it has helped the industry to up its maintenance game for many years.

He spoke about why maintenance is important. “Maintaining HVAC systems is essential to ensure optimum energy efficiency while maintaining the longevity of the asset,” he said. He also looked at excuses people use for not maintaining systems.

Scott then moved on to some practical tips to assist with maintenance as well as common mistakes contractors make, like using the wrong cleaning agent or process. He showed some interesting pictures of what can go wrong if you don’t do the job right and stressed the importance of preventative maintenance. “Maintenance is cheap compared to the risk of not doing it.”

He highlighted some products they use, specifically from the Goodway range. “HCM firmly believes in the importance of maintaining HVAC systems and in line with this have represented the world renowned Goodway range in South Africa for the past 25 years,” he explained.

From descaling systems and coil cleaning options to duct cleaning products, vacuum cleaners and pressure washers – there is a product for every job, not just in the HVAC&R industry. 

Scott and his team also brought along some of the Goodway products so guests could see how they work for themselves after the talk.

The talk was very well attended and everyone many questions, the conversation continued long after the formal presentation was over.
