Ductless Mini-Split Lifespan: How Long Should My Unit Last?

Most traditional air conditioners are able to last for at least 10 years. Ductless mini-split air conditioners can serve you even longer at 20 years under favorable conditions. Few home appliances can match this kind of lifespan. It shows that ductless mini-split systems are worth every cent. If you wish to achieve the higher end of the longevity spectrum, then you need to be mindful of the things that can affect it. Take proactive steps to prolong your ductless service life whenever possible.

Factors That Affect Ductless HVAC Longevity

Below, we discuss the factors that influence ductless mini-split longevity.

1. Level Of Care Your Ductless Mini-Split Receives

HVAC equipment needs regular care for peak performance and long life. You do not need to fuss about them every day but you should check the air filters every month or so. Clean these when they get dirty to sustain good airflow. You should also schedule professional maintenance at least twice a year. Certified technicians can open them up, inspect the components, clean the interiors, and conducts tests to ensure that everything is working well. They can make the necessary adjustments to keep the ductless system energy-efficient and problem-free.

2. Frequency Of Use

Using a heating and cooling system all the time will make the components wear out fast. People may have no choice but to depend on their HVAC system for most of the year if they live in a climate with extreme temperatures. The best that they can do to reduce system load is to use mild thermostat settings. Keep the indoor temperature between 71-78 Farenheight. This should be enough to keep everyone comfortable. Also, when you are away, be sure to turn the temperature down when your ductless mini-split is in heating and turn the temperature up when cooling. This keeps your energy costs manageable and reduces wear and tear on your system.

3. Quality Of Ductless Heat Pump Equipment

Ductless systems come in a wide range of qualities. Trained eyes can spot the cheap materials used in less expensive models. Although it may be tempting to purchase these low-cost systems, you should pause and remember other important considerations. Consult a reputable HVAC contractor to find better options. You can get expert information regarding equipment quality, warranty, brands, and related topics.


4. Proper Ductless Heating & Cooling Installation

HVAC performance and longevity will also depend on the competence of the HVAC installation company. After all, these people will assemble the parts onsite. They need to find ideal spots for the indoor and outdoor units. Furthermore, they should check for adequate clearance around these. They also have to ensure proper fitting for the connecting pipes and cables.

5. Correct Ductless Mini-Split Sizing

Getting a small ductless system will save you money but it may not be adequate for your home. An undersized HVAC unit will have to work harder and longer to reach your ideal indoor temperature. This will have a negative impact on lifespan. Installing an oversized system is also a bad idea. This can result in short cycling which can wear out the components quickly. Ask an experienced HVAC installer to calculate the exact power required for the home. Find a ductless system that can match the load.

6. Environmental Conditions

Certain environments are not conducive to HVAC system longevity. For example, homes located in coastal areas will have to deal with the salty air that hastens corrosion. Meanwhile, homes located in dry and dusty areas may find their air filters getting dirty fast. They will have to replace or clean their HVAC filters more frequently than others to prolong service life.


HVAC Lifespan: Ductless HVAC Versus Central HVAC Units

Ductless heat pumps generally outlive central ducted heating and cooling systems. To understand why this happens, it is important to appreciate the impact of their designs on the compressor. This is the heart of the system. Once it fails, it is usually time to get a system replacement. Compressor failures are often due to the following:

1. High Static Pressure

Incorrect duct sizing or installation can result in high static pressure. This stresses the system and triggers, for example, compressor overheating. Since mini-split systems are ductless, this is not a concern for owners.

2. Hard Starts

Repeated hard starts can cause major wear and tear on forced-air central systems. Ductless mini-split systems use inverter technology with variable speed to eliminate the problem. The compressors ramp up and down instead of going full speed at once.

3. Dirty Evaporator Coils

Leaky ducts suck in dirt and dust. These indoor air particulates can eventually settle on the surface of the system. For example, when the evaporator coils get dirty, it prevents the system from expelling heat effectively. It also makes the compressor work harder to compensate. Mini-split systems do not have ducts so leaks and dirt will not be as much of an issue.

Ductless mini-split systems have the clear advantage when it comes to lifespan. By getting rid of the ducts and improving the technology, they are able to operate more efficiently and run for a longer period. High-quality ductless HVAC systems can last for two decades with proper maintenance. This makes them excellent investments for any homeowner.
