The lifespan of an HVAC system varies depending on how often it is used and how well it is maintained. However, they eventually have a lifespan, and even with maintenance and repairs, at some point, even the best ones will come to the end of their life. In general, most systems last between 15 and 25 years. However, there are several factors that can affect how long an HVAC system lasts. In this blog post, we will discuss the factors that influence how long an HVAC system lasts and when you should consider upgrading your system.Schedule Your Heat Pump Tune-Up
The lifespan of an HVAC system is determined by how often it runs. Systems that are used more frequently will have a shorter lifespan than those that are used less often. In general, most HVAC systems last between 15 and 25 years. However, several factors can affect how long an HVAC system lasts. The service life of an HVAC system depends on its type. Here are the typical life spans for common HVAC equipment:
The average furnace lasts 20-30 years. If you want your furnace to last longer, ensure it's maintained with scheduled repairs and replacements. Systems that are not maintained regularly or the ones with questionable quality may last ten years. A furnace can be replaced when the heat exchanger starts leaking.
The average boiler lasts 20-35 years with proper maintenance. As with furnaces, if your boiler is regularly maintained, it will sometimes last longer – up to 40 years. It would be best if you replaced your boiler when the heat exchanger starts leaking or when the unit becomes inefficient.
The average central air conditioner lasts 15-20 years, though some may last closer to 10. The compressor is the most expensive component of an AC unit, so many homeowners opt to replace the entire system when the compressor fails. If you maintain your AC unit properly, it will last longer and be more energy-efficient.
The average heat pump lasts 10-20 years, depending on usage frequency, and 15 is average. As with other HVAC equipment, if you maintain your heat pump properly, it will last longer – up to 30 years in some cases. You should replace your heat pump when the compressor or other major components fail.
Like heat pumps, ductless mini-splits can provide heating and cooling, with a typical life span of 10-30 years. These systems are usually replaced when the compressor or other major components fail.
Even if these are the most common life spans, homeowners may choose to replace their HVAC system sooner. As the system is 10 -15 years old, repair and utility costs will increase, and it will gradually become less reliable and efficient. Therefore, upgrading to a more efficient model can often justify the initial investment, especially if the current system is unreliable or has significant problems.
There are many things that can reduce the life span of HVAC equipment, including:
Of these, maintenance is quite essential. How well you maintain your HVAC system will affect its lifespan noticeably. Regular maintenance – such as changing the air filter, cleaning the coils, and having annual tune-ups – will prolong the life of your system.
Whether your heating bill in winter or cooling costs in summer, your HVAC system needs to retire if your energy costs go up yearly. Remember, the average HVAC system lifespan is between 10–25 years, based on your climate and the type of heating and cooling system you have. But your system may last shorter if it has been overworked. A professional energy audit is the only way you can know if your HVAC is underperforming and overworked. You may be able to get a free energy audit through Sealed.
Suppose you or your family members have been experiencing more allergies, headaches, congestion, or respiratory problems since you've turned on your furnace or air conditioner. In that case, it may be time to replace your HVAC system. Your current unit might not have the right MERV rating for your home—or it could be that your ductwork is full of dirt and dust.
If you constantly have to call in a professional to fix your HVAC system, it may be time for an upgrade. Over time, parts will wear out and break down—and eventually, the repairs will start to cost more than a new system.
Is it too hot in the summer and too cold in the winter? Even if your outside AC unit constantly runs, your house still feels stuffy. Or maybe, there are uneven temperatures between rooms? These are general symptoms of a whole-house problem involving your HVAC system.
Upgraded insulation with professional air sealing and the best HVAC helps you resolve temperature problems while reducing the house's energy waste. Keep in mind that insulation and air sealing work together to form a crucial thermal boundary between the house's inside and the outside climate. Comfortable and—well—inside.
If your HVAC system still relies on fossil fuels—such as oil or gas—to generate heat, it's time to upgrade. Not only are these fuels bad for the environment, but they're also becoming increasingly expensive. If you want to save money and do your part for the environment, consider upgrading to a geothermal heating and cooling system. Using modern HVAC technology makes electricity a cheaper, cleaner, and more efficient energy source.
Geothermal systems use the earth's renewable energy to generate heat in winter and cool air in summer. These systems are not only more environmentally-friendly, but they're also more efficient, which means you'll save money on your energy bills. In fact, according to the U.S. Department of Energy, you can save up to 70% on your heating and cooling costs with a geothermal system.
If you're not ready for a complete HVAC upgrade, you can still save money and help the environment by switching to more efficient fossil fuels, such as natural gas.
If your air conditioner uses R-22 Freon refrigerants, it's time for an upgrade. The U.S. Environmental Protection Agency (EPA) has banned the production of this type of refrigerant, so it's becoming increasingly difficult (and expensive) to find.
If your air conditioner uses R-22 Freon, you may be tempted to wait until it breaks down before replacing it. However, we recommend upgrading now because the sooner you do, the more money you'll save in the long run. Newer systems use more environmentally-friendly refrigerants that are less expensive and easier to find.
When shopping for a new air conditioner, look for one that uses R-410A refrigerants. This type of refrigerant is more environmentally friendly and efficient, which means you'll save money on your energy bills. To know if your air conditioner uses R-22, check the detailed information on the condenser unit, your appliance manual, or call an HVAC professional.
Even if you take good care of your HVAC system, it will eventually reach the end of its lifespan. If your system is over 15 years old, it's time to start thinking about replacing it. While you may be tempted to keep using your old system as long as possible, remember that an outdated HVAC system is less efficient and could break down when needed. Moreover, your house is likely consuming way more energy than it should because of your ancient HVAC system. You don't have to pay more than you need to heat or cool your home. By upgrading to a new, energy-efficient system now, you can avoid being left in the cold (or heat) later on.
