The lifespan of a Ductless Mini-Split System: How Long Should It Last?

Most air conditioners will have a life expectancy of 10 years or more. However, under good conditions, a ductless air conditioner can provide 20 years or more of reliable service. There aren’t many home appliances that are able to provide a lifespan of this length. It just goes to show that a ductless mini-split system is worth every penny of the initial cost. If you want to make sure you get as many years as possible out of your ductless HVAC system, it’s important to pay attention to the things that could affect its long-term performance. When you are proactive in taking steps to prolong the lifespan of your system, it will reward you with optimal performance and years of service.

Factors Affecting Longevity of a Ductless HVAC System

1. The Level of Care You Give Your Ductless System

All HVAC equipment requires regular maintenance and care to achieve optimal performance. You don’t have to take care of it daily, but you should be checking the air filters about every month or so. When they get dirty, clean or replace it to ensure proper HVAC airflow. It’s also important to schedule maintenance a couple of times a year with a professional HVAC technician. A certified HVAC technician will inspect the various components, run some tests, and make sure everything is clean and working as it should. The technician will be able to make any necessary adjustments ensuring efficient, problem-free service from your ductless system.

2. Frequency Of Use

The more often you use your HVAC system, the faster the components will wear out. Of course, depending on where you live, you might not have a choice on whether you use your HVAC system just about every day throughout the year. If you use your HVAC system almost all the time, consider paying close attention to where you set the thermostat. Try to keep indoor temperatures somewhere between 71-78 degrees F. This should be comfortable for just about everyone. Additionally, when you’re not at home, turn your ductless system down if you’re using the heat function or turn it up if you’re using the cooling function. This can help reduce wear and tear on HVAC components as well as reduce your energy costs.

3. Quality Ductless Heating & Cooling Equipment

There is a range of quality options when it comes to a ductless system. A trained eye can easily spot less expensive models that use cheap materials. It might seem tempting to buy one of these low-cost systems, but you should consider some important factors. Ask a reliable HVAC contractor for help in finding the best option for your home. An HVAC contractor can give you expert information regarding brands, equipment quality, warranties, and other related topics for HVAC systems.


4. Proper Installation of a Ductless Heating and Cooling System

The professional installation of an HVAC system will help ensure the very best longevity and performance of your equipment. After all, when you choose a reputable HVAC contractor for the installation, they’ll put your system together onsite. They will find the best spots for both the outdoor and indoor units. They will also check to make sure there is enough clearance in these areas. Of course, they’ll also need to make sure that cables and connecting pipes are properly fitted.

5. Correct Size of the Ductless Mini-Split

If you have an HVAC unit that is undersized for your home, it will need to run longer and work harder to reach a comfortable indoor temperature. This can have a huge impact on the lifespan of the system. On the other hand, if you have an oversized system installed, it’s also a bad idea. The short cycling that occurs will quickly wear out components. An experienced HVAC technician can calculate the right ductless unit size for your home. You’ll find a ductless system that’s matched for the load that will offer the best performance and longevity.

6. Environmental Conditions

Some environments can reduce the longevity of an HVAC system. For example, a home in a coastal area will have to worry about the damage of salty air that can lead to corrosion. Meanwhile, a home in a dry, dusty area might find that air filters get dirty far sooner than in other areas. These homeowners will need to change their air filters more frequently to prolong the life expectancy of their system.


HVAC Lifespan: Central HVAC Vs Ductless Mini-Split Systems

Typically, a ductless heat pump will outlast a ducted central HVAC system. To understand the reasons for this, it’s necessary to appreciate the system designs and impact, and the compressor. The compressor is the system’s heart. If it fails, it usually means it’s time to buy a new system. A compressor will often fail because of the following issues:

1. High Static Pressure

Ductwork installation or HVAC duct sizing that is incorrect can result in the system experiencing high static pressure. The result is stress on the system, leading to overheating of the compressor. Obviously, since a mini-split system is ductless, homeowners won’t have to worry about this problem.

2. Hard Starts

Hard starts can lead to extensive wear and tear for central forced-air systems. The inverter technology used in a ductless mini-split system as well as the variable speed is able to eliminate this problem. Instead of starting at full speed, the compressor is able to ramp up or down, gradually.

3. Evaporator Coils That Are Dirty

Ducts that have leaks in them can suck in dust and debris. The particulates in the air will eventually become lodged on the interior surface of the system. Unfortunately, when evaporator coils are dirty, it can prevent the system from being able to effectively expel heat. This also makes it necessary for the compressor to work harder to compensate. A mini-split system has no ducts, so there are no leaks and the accumulation of particulates becomes less of a problem.
