The answer to 'when to replace AC repair' is that you should typically replace your air conditioning unit every 10-15 years, or when it becomes too expensive to repair. As air conditioners age, they become less efficient and more prone to breakdowns, which can lead to higher energy bills and more frequent repairs. If your AC unit is over 10 years old and requires frequent repairs, it may be time to consider replacing it with a newer, more energy-efficient model.
When deciding whether to repair or replace your AC, consider the age of the unit, the cost of repairs, and the potential energy savings of a new system. If the repair costs are more than 50% of the cost of a new unit, it's generally better to replace it. Additionally, newer air conditioners are much more energy-efficient, which can lead to significant savings on your utility bills over time.
