Replacing a split system air conditioner involves several steps, including selecting a new unit that is appropriately sized for the space, removing the old unit and associated components, installing the new unit, and testing the system for proper operation. It is important to hire a licensed HVAC professional to handle the replacement process to ensure that it is done safely and correctly.
The frequency of replacement will depend on several factors, including the age and condition of the existing unit, how often it is used, and how well it has been maintained. In general, a well-maintained split system air conditioner can last for 10 to 15 years or longer. However, if the unit is experiencing frequent breakdowns or is no longer providing adequate cooling or heating, it may be time to consider replacement.
Additionally, newer units may offer improved energy efficiency and other benefits that can make replacement a worthwhile investment.
