It's highly unlikely that your HVAC unit will last for 30 years before needing to be replaced. However, if you follow a regular preventive maintenance routine and operate it properly, you can increase your chances of keeping the same unit for about 15 years. Gas ovens usually last 20 to 30 years or even longer with proper maintenance. Furnaces are usually replaced when the heat exchanger starts to leak, as it is one of the most critical and expensive components.
Poorly maintained or questionable quality systems can last as little as 10 years, while oil furnaces usually only last 10 to 15 years due to maintenance problems caused by inefficient fuel. Air conditioners can last between 10 and 15 years, depending on several factors, while air conditioning systems can even last up to 30 years before needing to be replaced. What most homeowners don't know is that, even with a newer, more energy efficient air conditioning system, if your home isn't properly insulated or professionally sealed, the lifespan of the air conditioning system is automatically shortened. Many utilities will offer you discounts on heating, ventilation and air conditioning systems when you're ready to upgrade your air conditioning system. HVAC technology has advanced significantly over the years and your home's energy efficiency is affected by keeping older HVAC technology.
So it's time to think about a replacement, even if it “continues to work well”. But how do you know when to replace your home's air conditioning systems? What are your replacement options? And how can you get the air conditioning system you need without draining your bank account? For this reason, most HVAC technicians will recommend replacing any HVAC system that is 15-20 years old with a newer model and efficient. If you want to make sure that your HVAC system lasts as long as possible, it's important to follow a regular preventive maintenance routine. This includes changing the filters regularly, cleaning the coils and blower components, checking for leaks in the ductwork and inspecting the electrical connections. Additionally, you should also make sure that your home is properly insulated and sealed so that your air conditioning system doesn't have to work harder than necessary. By following these tips and taking good care of your HVAC system, you can ensure that it lasts for many years to come.
However, if you find that your system is more than 15-20 years old and is not performing as well as it used to, it may be time to consider replacing it with a newer model.
