Avoid expensive repairs as much as possible by keeping things in good running order year-round. Regularly clean out the vents under your fridge and in any air conditioning units. Change the lint traps in your dryer and vacuum cleaner often. Get the blades in your lawnmower sharpened each season and make sure to change the oil as needed. Have your heating ducts cleaned out annually. A little preventive maintenance can save you costly fixes and make appliances last longer.
Potential savings: $100 to $300 per year, if you can squeeze several additional years of life out of multiple appliances such as your washing machine, clothes dryer, vacuum cleaner or air conditioner.
