When is Time to Replace A Ductless Mini Split?

CM Heating - When is Time to Replace A Ductless Mini Split

A ductless mini-split system is a type of air conditioning and heating system that is designed to be efficient, cost-effective, and versatile. Unlike the central air conditioning units that we are all used to seeing, a mini-split is a small unit that provides heating and air conditioning to one room at a time. 

You know you have a ductless mini split when your air conditioning unit is on the side of the wall or window. These units work by using a compact outdoor unit that is connected to one or more indoor units through a small hole in the wall. This allows for precise temperature control in different parts of your home or office without the need for bulky ductwork.

However, like any other HVAC system, ductless mini splits also have a finite lifespan and will eventually need to be replaced. Here are some key signs that indicate it’s time for a ductless mini-split replacement.

1. Age of the Unit

The average lifespan of a ductless mini-split is 10 to 15 years. If your system is approaching or exceeding this age, it may be time to start considering a replacement.

2. Frequent Breakdowns

If your ductless, mini-split system is constantly breaking down or requiring repairs, it could be a sign that the system is approaching the end of its useful life. Eventually, a ductless mini-split replacement will be more cost-effective than paying for another repair. Frequent repairs can be costly, so it is important to weigh out these costs and determine whether a replacement would be the better decision.

3. Decreased Efficiency

Over time, ductless mini-splits can become less efficient due to wear and tear, or due to a lack of maintenance. If you notice that your system is not cooling or heating your home effectively, or your energy bills are gradually increasing, it may be time to consider a ductless mini-split replacement. However, if you want to expand the lifespan of your unit to the maximum, consider keeping up with a regular maintenance routine as this will help tremendously in preventing an early replacement.

4. Unusual Noises 

Ductless mini-splits are typically very quiet, so if you start to hear unusual noises coming from your system such as rattling, grinding, or hissing, it could be a sign that the unit is damaged or worn out. Sometimes a repair will fix that excess noise, so we highly recommend contacting a specialist in your area who would be able to troubleshoot the underlying issue of the noise.

5. Frequent Leaks

If you notice that there is water leaking from your ductless mini-split, it could be a sign of a refrigerant leak. This can be a potentially serious issue that will require immediate attention. If your system is leaking, it may be cost-effective to replace it rather than attempt to repair it. 

Regardless of your decision, we highly recommend contacting an AC repair technician who will be able to find the root cause of the leak and stop it from spreading or getting worse. Refrigerant fluid is very poisonous, and the excess moisture can also lead to the development of mold.

6. Poor Indoor Air Quality 

Ductless mini-splits include air filters to remove impurities from the air, but over time, these filters can become clogged, reducing their effectiveness. If you notice that the air quality in your home is poor, it may be time to replace your ductless mini-split with a new system that includes updated filtration technology. Consult a technician in your area about a possible ductless mini-split replacement.

7. Inadequate Heating or Cooling

If your ductless mini-split is no longer able to provide adequate heating or cooling to your home, it may be a sign that the system is too old or too small for your needs. A new, more powerful system may be necessary to meet your comfort needs. Plus, certain components of the unit wear out over time. As this unit approaches the end of its lifespan, it will begin to fail and its effectiveness will decrease with time.
