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 renewable energy products.

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 18 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.

“Thank you for all your help and advice with our amazing domestic air conditioning unit. From our first meeting you explained everything clearly, showing where the installation would sit, and how it would work. You were the only company who told us that only 5% VAT was applicable to certain types of heating and cooling  units.  The engineers who did the installation were lovely and they took great pride in their workmanship.  We are delighted we chose AAC. We have, and will continue to recommend you.  We also strongly believe we have received good value for money. Many thanks again.”

Jackie Finer, Bricket Wood
