When faced with the decision of whether to repair or replace your AC unit, several factors should be considered. Firstly, the age of your AC system plays a significant role. If your unit is approaching or exceeding its average lifespan (around 10-15 years), it may be more cost-effective to invest in a new one, as older units tend to require frequent repairs and may be less energy efficient.  Additionally, the extent of the repair needed and its cost should be evaluated. If the repair cost is substantial, it might make more financial sense to replace the unit, especially if it has a history of breakdowns.  Energy efficiency is another crucial factor to consider. Newer AC models are designed to be more energy efficient, which can result in long-term savings on your energy bills.  It’s important to consult with a qualified HVAC professional who can assess the condition of your AC unit, provide an accurate cost estimate for repairs, and offer recommendations based on your specific circumstances.
