On the other hand, power, especially over a large organization, and playing in a much bigger game is very interesting.
I spent 37 years largely without A/C, northern climate usually being below preferred room temperature. Heating, however, was essential. Moving south, both are surprisingly necessary as the area, while quite temperate on average, has annual temperature swings from about 25°F to 105°F - requiring HVAC.
Unless you're in an unusual situation, like high desert in a remarkably well-insulated home, I suspect HVAC is so prevalent in your life you've completely forgotten it's there out of familiarity. Mad King Ludwig of Neuchwuanstein Castle, however, would find much of the year uncomfortably cold - except that he'd completely forgotten it's there out of familiarity.
In fact, the only place where HVAC would be a "need" would be super cold climates, or super hot climates. Everything else is tolerable, just not comfortable. Plenty of places are hot, but people lived there just fine before we had electricity or any fancy cooling tech.
And a monarch would have more options for heating.
Traditionally heating was easier to come across than cooling, despite cooling taking less energy to have happen.
Now if you'd rather have a job which was notable in the 14th century, that's a different - and also interesting - discussion.
I never have. In fact if hospitals didn't exist and I never saw a doctor my entire life, I don't think anything would have changed.
I don't expect to live much longer than 60 as it is. Most 14th century monarchs, in the brief glance I did on Wikipedia before my answer, lived to 55 or 60 or so before they died of natural causes.
From this history.stackexchange[1] thread, on user found that the average age of death of monarchs to be 44 years in England. In the same thread it seem that it was 48.5 depending on how you made your calculation and 53.4 years if you made it to 20 year old.

FWIW: I’d have (probably) died from pneumonia at age 5 without modern medicine. In reality it was curable trivially.
That's the lifestyle explicitly being referred to when talking about swapping with a monarch.
And since we're talking 14th century, there was also that Black Death thing that killed about half the population of Europe.
