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 system at handover. That's the whole company. That's the point.

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

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.

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.

Say hello and see if we're a good fit.

Pick up the phone or drop me an email. I'd rather have a five-minute chat to understand your project than send a generic brochure.
