At the start of the season, add fresh gas and new engine oil to your snowthrower. Check the machine’s auger and impeller and make sure that the air filter and spark plugs are clean. At the end of the season, drain the gas and oil from the engine and clean the machine before storing it.
Small openings on the exterior of your home can allow for significant energy loss. Caulk around openings for electric, gas, oil and water supply lines, drainage pipes, plumbing for outside spigots, cable TV and telephone cables. Dryer vents, mechanical ventilation system vents and combustion air supply vents for furnaces should also be sealed.
