The system is antiquated and supremely inefficient. Your best action might be to make a suggestion that they replace it with an air-to-air heat pump system.
They might get tax credits for it, and it would pay for itself in reduced electricity bills.
You could perhaps even find a contractor willing to give a good price in hopes of getting further upgrades with them elsewhere.
I have suggested to Congress the best way to provide cheap, limitless heat to the entire country without increasing our carbon footprint one iota. But they ignore me, which shows they don’t take Global Climate Change (TM) seriously. I don’t even ask for any money for my idea as I’m not sure it’s something I can patent.
Simply pipe the hot air from the capital to wherever it’s needed. After the initial infrastructure cost the heat will be free. The only problem will be keeping it in DC in the warmer months. (You all know how hot DC is in the summer, right? This is why.)
Sadly I have no say in what they do.
