What Our Customers Say
“Absolutely fantastic service. A high quality job done quickly for a reasonable price by great guys. Can't ask for me than that”
— Thomas Hopwood
Google2026-09-05“We had air conditioning fitted a couple of weeks ago and honestly it is the best thing we have ever done. AGL were so professional throughout from the quote to the fitting and completed the works in such a quick timely manner leaving our rooms immaculately clean once they had finished. I would recommend them to anyone”

Google2026-09-05“Our boiler recently packed up and Gareth and the guys at AGL Heating sourced a new state of the art boiler for me before replacing my old boiler with it.
They were vety knowledgeable and gave me some best practice advice in relation to running it. As a consequence I have since seen considerable cost savings in my monthly bills.
The whole process from start to finish was super slick. Gareth and his team where not only professional and tidy but fairly priced also.
I couldn't recommend AGL Heating enough in terms of both their work and customer service .”

Google2026-09-05“Fast, efficient and above all, professional! Aircon install was a breeze, answered all my questions beforehand, scheduled an appointment and fitted no hassle. Quite possibly one of the best decisions I've made. Couldn't recommend enough, I'd give more stars if I could. Thank you Gareth!”
— Nathan Howell
Google2026-09-05“I can’t thank Gareth enough for all his help. From the very first time I contacted him to having our air conditioning fully installed, the whole process took just one week.
Throughout the process, Gareth kept me updated with the delivery status of the units, so I always knew when to expect the installation. His communication was excellent from start to finish.
On the installation day, I honestly expected the house to be left dusty and messy, but I was amazed. Once the job was finished, everything was left clean and tidy, as if nothing had happened.
A huge thank you to Gareth and his team for all their hard work, attention to detail, and professionalism. In today’s world, where it’s often difficult to know who to trust online, meeting someone as honest, reliable, and genuine as Gareth was a real stroke of luck.
I wouldn’t hesitate to recommend Gareth to anyone looking for air conditioning installation. Five stars all the way!”
— KWAN CHAN
Google2026-09-05“We used Gareth / AGL for the installation of two split aircon units in our newbuild. I spent quite a long time looking at reviews, because domestic aircon is still relatively rare. They sourced the units for us, and installed them. The work was professional, neat and thorough. Gareth and his team know their stuff - they answered all of my layman's questions patiently and clearly.
One of the units required tweaking some time later, and Gareth responded promptly. The aircon units [we went for LG, based on previous experience] have worked faultlessly since then, and we have been very comfortable through the various extreme hot and cold weather since then.
Highly recommended.”
