Precise Mini-Split Repairs

Mini-split units, also called ductless systems, are designed to be efficient, quiet, and responsive—but when something goes wrong, the disruption is hard to ignore. Maybe one room is stuck at the wrong temperature, or you’ve noticed unusual behavior like blinking lights or weak airflow. That’s when it’s time to call in a team that knows how to work with these systems from the inside out. At Moss Heating, Cooling & Plumbing, we approach every issue with a focus on accuracy and respect for your space. We don’t rely on guesswork—we investigate thoroughly, explain what we find, and fix the issue with care. Our goal is to restore full function to your equipment while giving you the confidence that it’s truly working the way it should.

Our Residential Mini-Split Repair Services

Mini-split units are compact, wall-mounted HVAC units that allow you to control the temperature in individual rooms or zones without relying on traditional ductwork. Each unit works with an outdoor compressor and is designed for efficient, room-by-room control, making it ideal for homes with additions, converted spaces, or areas that need extra attention. While they’re highly efficient and low-profile, these systems still require expert attention when things go wrong. Moss Heating, Cooling & Plumbing provides skilled repairs tailored to these unique components and layouts. Our technicians understand what matters most when servicing ductless equipment—and we’re committed to restoring performance with minimal disruption.

  • Accurate Diagnostics from the Start: We take time to inspect every component to locate the root of the issue. This allows for faster, more reliable fixes.
  • Quick Solutions for Common Failures: From electrical malfunctions to airflow problems, we’re ready to handle most issues during the first visit. Our trucks arrive fully stocked with tools and replacement parts.
  • Quiet Performance Restored: A noisy unit often points to a deeper problem. We’ll fix the source so your unit runs quietly and efficiently again.
  • Room-Specific Temperature Issues Solved: If one zone isn’t cooling properly, we’ll investigate why and make the necessary adjustments. We’ll make sure every room feels balanced to perfection.
  • Sensor and Thermostat Checks: We test controls and calibrate sensors to ensure accurate readings. A faulty signal can cause inconsistent cooling throughout the home.
  • Respectful Service in Every Room: We take care when working in bedrooms, offices, or other finished spaces. Protective gear and clean work habits are always part of the process.

I had a full system install with Moss Heating & Air and I am very pleased with the team I was assigned. I feel as if it was done right amd efficiently. I would highly recommend the team, even after they came back to replace my motor that was running loudly. So far so good and I am definitely looking forward to working with them in the future.

Carson was awesome! Professional, knowledgeable, friendly and listened. Many technicians want to tell you what they know. He had patience, understanding and then explained what is going on, based on his observations. He then did more than I expected. Measuring different air temperatures at the vents, and also checked the refrigerant in the A/C unit outside. It was slightly low. But in Texas, you can not expect much from A/C in the summer. He was polite, friendly, and represented his company in an exemplary fashion. He got down to business and did it efficiently. I love good service.
Thank you

Another great experience with Moss HVAC. We started noticing our downstairs AC had stopped cooling, over the weekend. So I left a message for Bobby, our main contact, last night (Sunday) and they sent us out a tech already today, Monday. Javier did an awesome job here. He determined iur system needed a new outside condenser fan motor and capacitor. Fortunately he had all the parts we neededz, on his truck, and we were up and cooling in about an hour. Thanks Moss team! Great stuff!
