Trusted local expertise for air conditioning & refrigeration.
Meet Ted
Ted McCarthy founded Ted McCarthy Services Ltd to deliver the kind of straightforward, quality service the AC and refrigeration trade is often missing — turn up on time, do the job properly, charge fairly, and stand behind the work.
With over two decades of hands-on experience across domestic air conditioning, commercial refrigeration, walk-in cold rooms and full building fit-outs, every job is overseen by Ted personally. That means consistent quality, clear communication and no being passed between subcontractors.
We provide air conditioning and refrigeration maintenance, repairs, installations and emergency call-outs across Hertfordshire, Buckinghamshire, Bedfordshire and London. Whether it's planned servicing for a commercial site, a broken display fridge in a shop, or a new AC system for your home, we deliver work you can rely on.

Our promise
A different kind of service
We know how frustrating it is to wait days for an engineer to call back, get vague quotes, or end up with messy installs and surprise invoices.
Our promise is simple: we'll communicate clearly, turn up when we say we will, recommend only what you actually need, and leave your site clean and your equipment running as it should.
That's why so much of our work comes through repeat custom and recommendations from satisfied homeowners and business owners across Hertfordshire and the South East.
