We had our furnace serviced, and the fire place done too, and a heating vent extended. The heating vent extension was limited to access, but better than it was before. As for the furnace and fireplace servicing, not much was done, used our vacuum to clean them, the furnace wasn't tuned (maybe it didn't need it?) but didn't seem like anything was done on those. Would call them again if we needed something, but would clarify what we were getting done first.
