About Our Company

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 26 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.

Great company and fantastic staff, Alex really went the extra mile, had the perfect install for my requirements. I’m so happy I will now be using them again to install AC at my work location.

Excellent service. Creative solution. The installation was clean, tidy and excellent. We wanted it installed in our bedroom, so it needed to be quiet and the unit is almost silent. We left Dave and his boys to do the installation whilst we were away on holiday. They came on time, they did a superb job and left everything spotless. I cannot recommend more highly

Your years of expertise resulted in great advice resulting in a very neat installation. Alex was great to work with and he got on well with the roofer, coordination was very good with minimum fuss, all done by 3.00 pm on the day.
