Since 1999, AAC has been serving London and the Home Counties from our head office in Welwyn Garden City. From our beginnings in air conditioning, our company has evolved and expanded to also offer installation and maintenance for ventilation and electrical services. At AAC we know that you have a choice and to that end we have always strived to offer the best customer service in our industry. After 22 years of trading a staggering 80% of our business is generated by either referral or repeat business. When you contact us, our operators will provide a personal, efficient response. You will be able to have an initial chat with a surveyor who will ultimately be the person to come to your premises to discuss your requirements. Once an agreement is reached, our engineers will arrive at the agreed time in our modern distinctive vans wearing uniforms bearing our familiar “swoosh” logo and complete their work in a tidy and professional manner.
