I get to talk to people about air conditioning and they seem to be quite interested, the drinks are free and the place is usually heaving with fantastically good looking women who all seem to smile at me and be willing to talk to me as well!

While at the show, I was telling all and sundry about the benefits of installing heat pump boilers and how brilliant they are.

In general people seemed to be quite receptive to my banter. It appears that anything with the words heat and pump in the title must be brilliant.

You try selling a split air conditioning unit -no chance. VRV, I'm afraid is old hat these days. Today all the people seem to want is an air to air heat pump, people can't get enough of them.

Now one of the other pleasures of attending a show is you get people coming to your stand trying to sell you things. From financial services, membership to organizations, shares in Nigerian banks and bizarrely the services of a magician.

They are also great places to meet people who you haven’t seen for ages or have been avoiding like the plague.

Fifteen years ago, I worked with an ultra religious air-conditioning salesman, many hours of my life were spent winding this poor creature up on site.

So, you can imagine my surprise when he turned up on the stand and told me he had put air conditioning on the back burner and had taken up magic as his new line of work.

'Magic Ian' is a master in the dark arts of the magic circle and for a small fee will come to your site, dazzle you with his skills and then quote you for a new air conditionng system. I'm telling you this guy is good.

What he can't do with an elastic band isn’t worth doing.

I came away from the show full of glee. I'd had a drink, spoken to some girls and confirmed that if air conditioning doesn’t work out, I can always become a magician. What a show!
