As autumn approaches disconnect hoses from outside hosebibs -- the valves on exterior walls for connecting yard hoses. These valves can split inside the wall if a connected hose (or other connected device) is exposed to freezing temperatures -- and here in Summit County (at 8700-plus feet above sea level) this can happen as early as late August or early September. You can still use the hose bibb -- to wash cars, water trees & shrubs (they especially need water late season!) -- just remember to disconnect the hose!
As winter nears, it’s a good idea to have your heating checked -- especially to insure safety of vents. Furnaces may need clean filters: blowers and draft inducers need cleaning.
Older furnaces may have stress cracks in the heat exchanger -- this means products of combustion -- flue gasses -- can mix with interior air flow. This condition presents a hazard to health and safety of occupants. Masterwork can conduct a test for carbon monoxide in the heated air space.
I recommend gas appliance vents be inspected annually. I often see vent connectors -- the single wall metal vent between appliance and chimney -- deteriorated, sometimes to the point of being crushable by hand ! This most often occurs with boilers that operate at lower-than-designed water temperature (e.g. some radiant systems) -- this causes water vapor in flue gas to condense -- the condensate is very corrosive, thus damaging vent materials.
