For any homeowner, HVAC Equipment is an essential investment to maintain comfort in the home. We often tend to use them as much as possible to get the most out of them. Generally, with regular usage, the HVAC system lasts around 15-20 years. The type of system and several factors contribute to its reliability, and it can vary. In this article, we will look into the topic of HVAC system lifespan and replacement.
Each HVAC system has a different lifespan. Below, we have mentioned the approximate life spans for common HVAC equipment we use in our daily routine.
Gas furnaces can last 20 to 30 years or more with proper care and maintenance. Most people replace their furnaces when the heat exchanger, which is a key component in the furnace, starts leaking. Furnaces that aren’t properly maintained or are of low quality might only last about 10 years. Oil furnaces usually last 10 to 15 years because the inefficient fuel can cause maintenance issues.
Boilers usually last longer than furnaces, with an average lifespan of 20 to 35 years. They are replaced when the heat exchanger starts to leak.
Most air conditioners last 15 to 20 years, but due to environmental conditions, some last only 10 years. In coastal areas, they usually last 7 to 12 years because of salt exposure in the atmosphere. Air conditioners and heat pumps are often replaced when the compressor faces complicated issues, or the condenser becomes heavily corroded and leaks.
Heat pumps last for about 10 to 20 years, while you can assume 15 years as an average lifespan, depending on their usage. They work like air conditioners, but their usage will be more since they provide both heating and cooling. In coastal areas, heat pumps last only about 7 to 12 years because of salt exposure and wear out faster.
Similar to heat pumps, ductless mini-splits provide both heating and cooling to the living space. They usually last for about 10-25 years, but the range may differ in coastal areas.
These are typical lifespans, but many homeowners replace their HVAC systems earlier. Systems become less reliable and efficient as they age, leading to higher repair and energy costs.
The following factors are responsible for the increase or decrease in the lifespan of your HVAC system:
Regular maintenance is important for keeping your HVAC system running efficiently and last longer. Avoiding routine check-ups and tune-ups can cause faster wear and tear and shorten the system’s lifespan.
The quality of the HVAC system and its maintenance greatly affect its reliability. Poorly installed or low-quality systems fail early, while high-quality units installed by skilled professionals are more likely to last longer.
Choosing the right size is essential for optimal performance and longevity. An HVAC system that’s too large or too small can run inefficiently and put extra pressure on its parts, shortening its lifespan.
Using your HVAC system too much or putting high demands on it can stress the system and shorten its lifespan. On the other hand, using it moderately and avoiding things like heating or cooling while doors and windows are open can help it last longer.
Environmental factors like coastal areas or extreme temperatures can increase the wear and tear of HVAC systems. Salt exposure and intense heat or cold can damage components and shorten the system’s lifespan.
Regular maintenance is crucial for the better functioning of your HVAC system. It is advisable to inspect, clean, and tune up your device every year. Summer and early winter may not be a good time for it, but you can ask your HVAC contractor to check your HVAC system in spring.
A typical HVAC tune-up means inspecting and lubricating all moving parts, cleaning the condenser, clearing debris from the condensate drain tube, checking refrigerant levels, air filters, and the heat exchanger for cracks.
An HVAC contractor will check your filters during regular visits, but later, it’s your responsibility. Most homeowners use disposable or pleated filters, which should be checked regularly every 30 days to 3 months. Even if it’s not time yet, you should replace the filters if they’re clogged and dirty.
Smart thermostats are easy to set up and can be controlled by using your smartphone or tablet. Some models even adapt to your heating and cooling habits, making energy-saving adjustments without any need for programming. Installing a smart thermostat and regular maintenance is one of the best ways to help your HVAC system last longer and save money. Smart thermostats differ from regular thermostats, which can help extend your HVAC system.
Your HVAC system lasts longer only if it runs less. Insulation helps keep warm or cool air inside, making your system work less. If your home’s insulation isn’t enough, your HVAC system must work harder and run longer to maintain a comfortable temperature. This extra work puts more stress on the system and increases both energy and maintenance costs. If your home has drafts of not having insulation in certain areas, consider adding insulation to your basement or outer walls.
Ducts are important for your HVAC system and indoor air quality. Duct cleaning involves cleaning parts of your HVAC system, from the air ducts to the registers and grilles. Cleaning your ducts every five years helps improve air quality and optimizes your HVAC system’s efficiency and lifespan.
By understanding what affects your HVAC system’s lifespan and using regular maintenance, you can enjoy reliable heating and cooling in the long run.
