If you have an older central air conditioner that does not cool well, it may be time to replace it. Central air conditioners generally last about 15 years, though newer ones may have a longer service life. The costs for cooling system maintenance can add up, especially with older models. Here are questions to ask yourself when deciding whether to invest in a new central air conditioner:
1.) Is the air conditioner requiring frequent repairs, making it less cost-efficient?
2.) Do you need to replace costly major components, such as the compressor?
3.) Will it be more affordable in the long run to replace your old system with a more efficient unit that will lower your monthly electricity costs?
4.) Is your warranty still good? Ask the manufacturer. Warranties generally vary from one year for parts and labor to five years for compressor replacement. But some manufacturers now offer 10-year warranties.
