    They may be

    up against higher expectations (80F desired vs. 68, 70, 72F), coupled with what may be lower than design outside temperatures and against what the system can do.

    If fins are dirty, a soft brush attachment on a Shop Vac should do it.

    On the boiler side, an annual cleaning and combustion test will tell you more than I could. How is their fuel usage compared to prior years?

    Also, as houses age, things settle, windows do not close as they once did. Install a new dryer in a new location and forget to close off the old vent... things like that.
