Best Practices for Maintaining (and prolonging the lifespan) your Ductless Mini Split

Mini Split Maintenance: How The HECK Is It Done?

You want your customers to be happy with their new mini split.  

Mini split maintenance helps them get the most out of their new purchase. Well-maintained mini splits can last up to 20 years or even longer! 

In this brief post, we will discuss mini split AC maintenance and how to service a mini split as an HVAC tech.  

Why Mini Split Maintenance is Important 

All heating and air conditioning systems demand maintenance to operate correctly, but with ductless mini split systems, it's mandatory.  

Energy Use  

Mini splits rely on free-flowing air circulation on the system's indoor and outdoor parts. The harder it is for the ductless system to operate, the more energy costs rise.  

Some research suggests that a poorly maintained mini split uses up to 25 percent more energy than a properly maintained one. Since one of the advantages of a ductless system is its energy efficiency, maintenance is critical.  

Damage to the Unit 

A lack of clean air filters also damages the indoor components of the mini split unit. Dirty filters are notoriously bad for ductless units, so it's a good idea to start your mini-split system maintenance there.  

Longevity  

Ductless AC maintenance is also important for the life of the system. The better care you take of them, the longer they last. Help customers stay satisfied with their purchase by servicing their mini splits regularly.  

Best Practices for Mini Split System Maintenance

For the best results, we recommend that you service mini split systems every year or every two years. Here are a few best practices for that maintenance process.

Inspect The Unit  

Regular inspections are a crucial part of mini split maintenance. An inspection tells you: 

• The condition of the unit 
• Parts that need to be replaced 
• Unusual wear patterns  
• Electrical issues 

When you inspect a mini split AC system, remember to look at the following: 

• Electric wire or tubing rubouts 
• Electrical connectors  
• Refrigerant connections 

Remove and Clean Air Filters  

The AC and heat pumps for ductless mini split systems require clean air filters to function correctly. Take out any air and dust filters, clean them, and replace them as needed.  

Clean the Drain Line & Condensate Pump  

The drain line and condensate pump should be inspected and cleaned with each maintenance performance—typically every 12 months. 

Run A Test  

After you've cleaned and inspected the mini split system, it's time to plug it all back in and see if it's working correctly. Once everything is back where it ought to be, do the following: 

• Leave the bib in place and run a blower to remove excess moisture 
• Listen for any out-of-the-norm noises 
• Test both heat and AC settings  
• Turn the system to full cool to see if it's operating right 

Take Measurements  

Measurements are the key to a good maintenance check. Even if something's slightly off the normal measurement, it can be a big red flag for your unit. Here's what to measure: 

• Suction pressure and superheat at full cooling 
• Applied voltage 
• Outlet air temperature 
• Compression, CFM Amps, and Blower
