Honest advice
If AC isn't the right answer, I'll tell you. If a cheaper unit will do the job, I'll recommend it. My reputation matters more than one sale.
Hi, I'm Robert Lyons, the Air Conditioning Guy.
I'm the person on the end of the phone, the person who walks into your home to do the survey, and the person who switches on your new air con at handover. That is the whole company, and that is the point. Twenty-five years in the trade, working across North London.
The story
Twenty-five years of getting it right the first time.
My journey started in construction: learning how buildings breathe, where heat goes, why some rooms always feel wrong. Air conditioning came later, and for the last two decades it's been my full-time craft.
Over that time I've seen enough bad installs (badly sized units, ugly pipe runs, noisy outdoor condensers in the wrong place) to know the difference a careful engineer makes. That's the standard I hold every Climatemix installation to.
I work on my own, deliberately. A one-person operation means you deal with the same person from survey to sign-off. No handovers. No miscommunication. Just the same pair of hands, every step.
What I stand for
Four values you'll notice from our first conversation
Fixed-price quotes
Every quote is itemised, written and fixed. No mid-job surprises, no "while we're here" add-ons creeping onto your invoice.
Personal service
One engineer, from first call to final commissioning. You never have to explain your project twice, or chase a different contact.
Quality workmanship
Careful pipe runs, level units, hidden cabling, clean paint. Thirty years of trade pride baked into every installation.
No sales pressure
Quotes land in your inbox and stay there. Take your time. I'll follow up once, politely, then leave the ball in your court.
Longevity over shortcuts
A system installed properly lasts 15+ years. Cut corners now and you'll pay for them every summer. We don't cut corners.

Accreditation
Properly certified, and here is what that means
Most air conditioning credentials are meaningless to the person paying for the job. These are the ones that are not, and what each actually tells you.
REFCOM registeredF-Gas scheme
REFCOM is the F-Gas registration scheme run by the Building Engineering Services Association. It certifies that a company is legally permitted to handle fluorinated refrigerant gases.
Without it, an installer cannot legally work on a split system at all.
F-Gas certified engineerCity & Guilds
The individual qualification for handling refrigerant. It covers safe recovery, leak testing, charging and decommissioning.
It is the engineer holding the gauges who needs this, not just the company on the invoice.
Public liability insuranceFully insured
Cover for damage to your property while work is in progress, alongside professional indemnity.
Ask any installer for the certificate. A legitimate one will send it without hesitating.
25+ years in the tradeSince 1999
A quarter of a century across construction and air conditioning, most of it in London period property.
Experience is not a certificate, but it is why the awkward jobs go right.
One thing worth checking on any quote you receive
Air conditioning needs F-Gas certification, not Gas Safe. Gas Safe covers gas appliances such as boilers and is the wrong credential entirely for refrigerant work — yet it appears on a surprising number of air conditioning websites. If a company is displaying Gas Safe for an air conditioning job, ask them for their F-Gas registration before you go any further.
