When it comes to keeping your home comfortable, the HVAC system is one of the most important pieces of equipment. It’s also a major investment that you want to last for as long as possible. But how long should you expect your HVAC system to last? The answer isn’t cut and dry, as there are several factors that can determine the lifespan of an HVAC system.

In this article, we’ll discuss what factors determine how long an HVAC system will last, provide some tips for extending its lifespan, and explain why it’s important to call an experienced professional when it comes time for maintenance or replacement.

The lifespan of an HVAC system can vary depending on several factors, including the type of system installed and how well it is maintained. With proper care and maintenance, many systems can last up to 15 years or longer. However, other systems may need to be replaced after only 10 years due to lack of maintenance or other issues.

No matter what type of system you have in your home, it’s important to understand what factors affect its longevity so that you can take steps to ensure that it lasts as long as possible. Here are some of the most common factors that determine how long an HVAC system will last:

Factors affecting the lifespan of an HVAC system and tips to extend its life are discussed. Proper care and maintenance can help HVAC systems last up to 15 years or longer.

What Factors Determine How Long an HVAC System Will Last?

The lifespan of an HVAC system will vary greatly depending on a few key factors. The type of system, regular maintenance, and fuel burning can all determine how long the system will last before it needs to be replaced.

Type of HVAC System

The type of HVAC system you have installed in your home will play a major role in how long it lasts. A split system is typically the most reliable and can last up to 20 years with proper care and maintenance. On the other hand, a window unit or portable air conditioner may only last for 5-7 years due to their smaller size and lack of energy efficiency.

Regular Furnace Filter Changes

The furnace filter should be changed every three months or more frequently if needed. This helps to keep dust and dirt from clogging the system and reduces wear and tear on the unit over time. Not changing the filter regularly can lead to increased energy costs as well as reduce the life expectancy of your HVAC system.

Fuel Burning Cleaner

If you have a fuel-burning furnace, it’s important to use clean burning fuel such as natural gas or propane in order to extend its life span. Dirty fuels such as oil can cause build up in the combustion chamber which can lead to premature failure of your furnace over time.

Boiler Type

Boilers are typically more durable than furnaces since they don’t have any moving parts that could break down over time. However, boilers still require regular maintenance such as checking for leaks or corrosion which can reduce its lifespan if not caught early enough. Boilers can last anywhere from 10-15 years depending on how well they are maintained.

Type of HVAC SystemLife Expectancy
split systemUp to 20 years
Window Unit/Portable Air Conditioner5-7 Years
Furnace Filter Changes<3 Months
Fuel Burning Cleaner>Clean Burning Fuel (natural gas, propane)
Boiler Type>10-15 Years (with proper maintenance)

Best Tips For Extending The Lifespan Of Your New System

Having a new hvac system installed in your home is an exciting time, and you want to make sure that it lasts as long as possible. Fortunately, there are a few steps you can take to ensure that your system runs optimally for years to come. Here are the best tips for extending the lifespan of your new system:

Refer to Owner’s Manual

The first step in ensuring that your HVAC system runs well for years to come is to refer to the owner’s manual. This document will provide you with all of the necessary information regarding how to properly maintain and use your system. Make sure that you read through this manual thoroughly so that you can understand all of the instructions and guidelines related to your particular model. Additionally, if any problems arise, be sure to contact the manufacturer or a certified technician for assistance.

Proper Filter Size and Maintenance

The size of the filter used in your HVAC system is incredibly important when it comes to prolonging its lifespan. If the filter is too small, it won’t be able to effectively capture dust particles and other debris which can cause damage over time. On the other hand, if it is too large, it will restrict airflow which can also lead to issues down the line. To avoid these problems, make sure that you always purchase filters which are designed specifically for your model and change them out regularly according to manufacturer recommendations.

Regular Furnace Filter Changes

In addition to making sure that you have the right size filter in place, you should also be sure to change out furnace filters on a regular basis. Doing so ensures that dirt and debris don’t accumulate within your system which can cause wear and tear on components over time. Generally speaking, most manufacturers recommend changing out air filters every three months or so depending on usage levels.

Fuel Burning Cleaner

If you have a fuel burning furnace or boiler in your home, then using a fuel burning cleaner can help extend its lifespan significantly. These cleaners work by removing carbon deposits from internal components which can lead to buildup over time if left unchecked. Using one of these cleaners every six months or so will help keep things running smoothly while also reducing wear on parts due to excessive buildup.

Boiler Type

Finally, it’s important to consider what type of boiler you have installed in your home when looking at ways to extend its lifespan. Boilers with cast iron heat exchangers typically last longer than those with aluminum ones since they tend to be more durable over time. Additionally, boilers with condensing technology have been known to last up 20% longer than traditional models due to their increased efficiency levels.
