An air conditioning appliance at your home should last 15 to 20 years, per EnergyStar, a voluntary programme of the United States Environmental Protection Agency. However, this only happens when you schedule regular upkeep and maintenance throughout its service life.
If you overlook routine servicing of your cooling appliance, it might succumb to frequent breakdowns leading to costly repairs. While smaller breakdowns and issues with your cooling appliance are worth it, you must get the machine replaced if the repair expenses are more than half of the unit's price.
