Ductless Mini-Split Repair in San Diego

Ductless mini splits are a relatively new technology in the air conditioning and heating world. First introduced in the 1970’s, it has only been in the last 8 years or so that these heat-pump type systems have increased in popularity in the U.S. market. Repair and service requirements for ductless mini splits in San Diego differ somewhat from repair for traditional HVAC systems, so it’s important to count on highly experienced service technicians to address mini split problems.


Mitsubishi Electric is by far the largest manufacturer of ductless mini split systems in the world. Carini Heating, Air and Plumbing was recently given an award as the #1 seller of Mitsubishi ductless systems in all of Southern California. This includes companies throughout Los Angeles, Orange and Riverside Counties. Carini is a Diamond Elite Contractor for Mitsubishi, meaning our installer, service techs and design specialists are factory trained and certified.

Here are some of the most common reasons that ductless mini splits need repair:

Fan in the Outside Condensing Unit Stops Running

This kind of situation could be caused by loose or disconnected wires or power problems with the unit. A frozen fan motor could also be the culprit.

Capacitor Problems

Capacitors are located inside air conditioning systems. “Start”capacitors send voltage to the motors that drive the fans and the compressor to start them operating. “Run” capacitors, send voltage at regular intervals to maintain motor operation. Capacitors are sensitive to high heat levels, so during very hot summers, excessive and prolonged heat can shorten a capacitor’s lifespan.

Dirty Filters

Air filters on ductless mini splits need to be changed regularly, just like in traditional air conditioning systems. Click here for a useful article about the different types of filters you might consider for mini splits.

Refrigerant Leaks

Refrigerant leakage is a problem that can occur in mini split or traditional whole home HVAC systems. Refrigerant is circulated between the indoor and outdoor units through insulated refrigerant lines. These lines can become damaged by outside weathering, human contact or holes from animal infestation.  Diagnosing refrigerant leaks can require various testing methods that should only be performed by highly trained technicians, such as our factory trained and certified service techs.

Other common reasons for ductless mini split repair and service include problems with indoor air handler remote controls; Problems with power supplies; and water leaks due to condensate issues.
