Our upstairs HVAC system stopped making heat when it’s not using the electric add-on heat.

It looks like we may have a refrigerant leak… because it had to have gone somewhere, no?

We added (well, the tech did) a pound of R22 to top it off.

But I’m guessing in the spring we’ll have to replace the entire system. It’s rattle-y and doesn’t work well. Works for now… but yeah.
