The answer to 'how often to replace HVAC repair' is that most HVAC systems should be replaced every 10-15 years. The lifespan of an HVAC system can vary depending on factors like usage, maintenance, and the quality of the equipment. However, as systems age, they become less efficient and more prone to breakdowns, so it's generally recommended to replace the entire system once it reaches 10-15 years old.
Regular maintenance and repairs can extend the life of an HVAC system, but at a certain point, it becomes more cost-effective to replace the entire unit rather than continuing to repair it. Signs that it may be time to replace your HVAC system include frequent breakdowns, higher energy bills, and the system being unable to effectively heat or cool your home.
