It's highly unlikely that your air conditioning unit will last 30 years before it needs to be replaced; however, if you take the necessary steps to maintain it and operate it properly, you can increase your chances of keeping the same unit for about 15 years. With regular preventive maintenance, gas ovens usually have a lifespan of 20 to 30 years or even longer. On the other hand, a furnace is usually replaced when the heat exchanger starts to leak, as it is one of the most critical and expensive components. Poorly maintained or low-quality systems can last as little as 10 years, while petroleum furnaces usually only last 10 to 15 years due to maintenance issues caused by an inefficient fuel. For this reason, most HVAC experts recommend replacing any HVAC system that is 15-20 years old with a newer, more efficient model.
This will help you save money in the long run by reducing energy costs and ensuring that your home is comfortable all year round. If you want to make sure that your air conditioning unit lasts as long as possible, it's important to keep up with regular maintenance. This includes changing the air filter regularly, cleaning the coils and fins, and checking for any signs of wear and tear. Additionally, you should have your unit inspected by a professional HVAC technician at least once a year to ensure that everything is working properly. By following these simple steps, you can help extend the life of your air conditioning unit and ensure that it runs efficiently for many years to come.
