With proper and regular care, standard A/C units can last up to 20 years. It is important, however, that homeowners know when it is time to replace an old unit. Otherwise, they will be left with an energy-hogging, poorly functional A/C.
When choosing the right size, brand and model for your new A/C, consider the following:
- Room size and energy efficiency
- Number of household members, lifestyle, and thermostat settings
- Budget and long-term expenses
