It’s easier than you might think to determine whether to fix or nix your creaky refrigerator or temperamental stove, and doing the simple research could save you big, says Angie’s List Founder Angie Hicks.

“Large appliances are a long-term investment but many consumers don’t get their full money’s worth,” says Hicks, whose company collects consumer reviews in more than 425 service categories, including appliance repair.

New appliances could cost thousands. The average service call ranges from $60 to $100. The call charge doesn’t include parts and labor, but many service pros will forgive the initial fee if they get the repair job.

With proper maintenance and use, consumers should expect 10 to15 years of good life out of refrigerators, freezers, dishwashers, washers, dryers and central air conditioning units. Ovens, ranges and water heaters should hold up for 10 to 20 years.

10 questions to determine whether to fix or nix a major appliance:

1. Is it really broken? Check the troubleshooting section of the unit’s manual for guidance and also check plugs, cords, circuit breakers and surge-protectors.

2. Is the first time the unit has had a problem or does it have a long, bad history?

3. How old is the appliance?

4. How much will it cost to repair the unit?

5. Are there additional costs to remove, install, dispose of your existing unit?

6. What would a new appliance cost?

7. Are there renovation costs attached to a new unit or can it slide right into place?

8. What new, useful features will a new appliance offer?

9. Will energy savings make it more affordable to nix vs. fix?

10. Will tax credits on your purchase make it more affordable to nix vs. fix?
