A Bit About Me

I’m an HVAC contractor in Espoo.

That’s the official version.

The more accurate version is that I spend a large part of my life thinking about air, pressure, moisture, machines, people, schedules, old buildings, new problems, and the strange optimism required to make all of those behave at the same time.

HVAC is the day job. It is also most of the energy budget.

When there’s something worth saying, I write essays in Finnish. I’m also working on a novel and a tabletop RPG, at the pace life currently allows.

Most weeks, that pace is theoretical.

I came to Finland in 2006 because of love, which is a very normal reason to move countries and a very efficient way to redesign your entire life without fully reading the manual first. After that came the practical phase: dishwashing, digital services, a few professional side quests, and eventually a degree in media technology engineering from Metropolia University of Applied Sciences.

Then Nokia collapsed.

This was inconvenient for the career plan.

So I went back to school and became a plumber. Somewhere along the way I alsoattended an HVAC engineering degree and acquired a stack of smaller qualifications: property maintenance, ventilation, CAD/BIM, humidity coordination, thermal imaging. The pile grew. The pattern became visible.

Ventilation was the thing.

It still is.

There’s something about ventilation that feels bigger than ducts and fans. Air means freedom. Air means life. Both are precious. Both are easy to take for granted until they stop moving properly.

I think symbolism is allowed in career choices too.

I became an entrepreneur when the company I worked for as a foreman drifted out of the market. That sounds tidy written in one sentence. In real life it was messier, because real life usually has worse documentation.

I assembled a team. That part matters. A business is not an idea in a notebook or a logo on a van. It’s people who know what they’re doing, show up, solve problems, carry responsibility, and somehow keep the system running when the system would prefer not to.

Without those professionals, the company would never have got off the ground.

The best part of the work is still solving clients’ problems. Every project has its own little ecosystem of constraints: the building, the budget, the schedule, the regulations, the existing installation, the thing nobody noticed until the ceiling was open.

That’s where the work becomes interesting.

Being close to the day-to-day also keeps the talk honest. I’m not writing about HVAC from a showroom. I’m writing from inside the machine room, usually with dust somewhere it shouldn’t be and coffee acting as the only stable measurement device.

Work matters, but recharging matters too.

For me that means role-playing games, Magic: The Gathering, fantasy literature, and other structured ways of escaping reality without fully abandoning the rules. My favorite book is The Name of the Wind by Patrick Rothfuss. I also like hiking with the family, barbecuing in the backyard, a good glass of wine, and long conversations that start with one topic and end somewhere completely different three hours later.

​

At home I have a wife, five children, two cats, which is actually three, and a shifting number of chickens.

So, although it may sound that way, I cannot really claim that everything is going smoothly.

The critical systems, however, are still running.

I am not at all sure, by the way, that anyone’s life ticks along like a Swiss watch. Everyone is just adjusting the airflow as they go, trying to keep the pressure balanced and the home livable.

I think that is enough.
