Home / About Us

Air Technical Services Ltd is a well established family run business. The managing director, Andy Rossides, has many years experience in the fields of air conditioning and electrical contracts. He controls the day to day running of the company, and is actively involved in the management of all projects and installations, ably assisted by his team of skilled professionals.

Air Technical Services Ltd’s mission is to provide first class electrical and air conditioning installation and maintenance services from our base on the Hertfordshire/Essex border. We have carried out contracts for clients in the public and private sectors, retail, commercial, industrial and domestic markets. Although we mainly operate throughout Hertfordshire, Essex, Bedfordshire, London and the South East we also undertake projects in other areas of the UK.

We consider quality of service is vital and we are fully committed to providing a safe and healthy working environment. Health and Safety considerations form an integral part of all our working practices. Systems are reviewed regularly and are fully supported by the management team and employees.

We are members of the Mitsubishi Electric Partner Programme and as such are committed to demonstrating competence in key areas such as Installation, Commissioning, Maintenance, Health and Safety, Corporate Social Responsibility and Refrigerant Handling.
