Air conditioning installation
Really pleased with the work carried out. The installation was done to a very high standard and everything was incredibly neat and tidy. Ollie took great care in my home and left everything spotless afterwards. This is going to make such a difference to my health conditions. I’m incredibly grateful. He is reliable professional and I won’t hesitate to recommend him. Excellent service.Job location: CO16Remma s10 Air Conditioning Installation

A/C fitted in lounge and main bedroom
We decided to give the work to a small business rather than a larger company, pleased we did. Excellent job from quote visit to completion. Olly was punctual and friendly doing an excellent job in a single day as planned. Cleaned all mess away afterwards and left the work areas tidy. We would highly recommend him for any A/C work you need doing.Verified reviewerJob location: IP8RAndy R10 Air Conditioning Installation

Top guy - fantastic tradesman - outstanding service - hire him!
Ollie is not only a lovely guy, he is an extremely competent, hard working and professional tradesman. He advised upon and fully installed a large ducted a/c system and the service end to end has been fantastic. He always puts his customers first, is a pleasure to deal with and is extremely competitive on price. Don’t just short list him - hire him!Verified reviewerJob location: IP2910 Air Conditioning Servicing

A good guy and a great service!
Ollie has been servicing my airconditioning units for a number of years now, and I would recommend him wholeheartedly to anyone looking for aircon installation/maintenance Warm, trustworthy, and reasonably-priced, he is also, most importantly, expert at what he does. I have never had an issue he has not been able to identify and resolve with extreme efficiency.Verified reviewerJob location: SW710 Air Conditioning

Hi, I’m Ollie from OGAC, an experienced air conditioning engineer with 16 years in the industry, working across both domestic and commercial environments. I carry out repairs, installations, and servicing, always taking the time to understand my customers’ needs.
I’m friendly, approachable, reliable, and I take real pride in my work, with strong attention to detail and care on every job. I believe good after-sales support is just as important as the initial work, which is why I’m always happy to continue supporting my customers through regular preventative maintenance.
With a strong focus on delivering a high standard of after-sales care, I place great importance on annual deep cleaning and regular filter changes, tailored to how each system is used. By using specialist equipment and professional disinfectants, I ensure all units are thoroughly cleaned, maintained, and operating efficiently.
My installation work ranges from small single units in gyms, offices, homes, and clinics, through to multi-system installations in hotels and larger commercial complexes.
Please get in touch, call or email, always happy to have a chat.
