Common Mini-Split Problems We Address

Mini-split systems have intricate designs and can develop issues distinct from traditional central air units. Our technicians are trained to identify the exact cause and deliver targeted solutions.

Unit Running but Not Cooling

A system that powers on but fails to cool often points to an issue in the heat exchange process.

1. Refrigerant Leaks – Low refrigerant from leaks in the lines is a common problem. We use advanced leak detection tools to seal the source and recharge the system to the manufacturer’s specifications.
2. Compressor Failure – The compressor is the system’s core. If it malfunctions, cooling stops entirely. We diagnose both electrical and mechanical issues to restore operation.
3. Dirty Coils or Clogged Filters – Dirt and dust on coils hinder heat transfer, while clogged filters restrict airflow. Our deep cleaning restores cooling efficiency.

Water Leaking from Indoor Unit

Water dripping from the indoor air handler needs immediate attention to avoid damage.

1. Clogged Condensate Drain – Debris buildup can block drainage, causing overflow. We clear blockages thoroughly.
2. Frozen Evaporator Coil – Low refrigerant or restricted airflow can cause ice buildup, which melts and leaks. We address the root cause to prevent recurrence.

Strange Noises or Foul Odors

Mini-splits should operate quietly. Any unusual noise or smell is a sign of trouble.

1. Mechanical Noises – Grinding, rattling, or squealing may indicate loose parts, failing motors, or debris. We repair or replace components as needed.
2. Musty or Moldy Smells – Odors often result from mold growth inside the unit. We clean and sanitize to improve Indoor Air Quality.

System Won’t Turn On or Cycles Erratically

If your mini-split is unresponsive or turns on and off unexpectedly, the cause is often electrical or sensor-related.

1. Power Supply Issues – From tripped breakers to wiring faults, we trace and fix electrical problems.
2. Thermostat or Sensor Malfunctions – Faulty controls can send incorrect signals. We recalibrate or replace components to restore accuracy.

Quick Troubleshooting Before Scheduling Service

Sometimes small fixes can resolve the problem:

1. Ensure the remote control has fresh batteries and is set to “Cool” mode.
2. Check and clean the air filter if clogged.
3. Reset the power by switching off the breaker for one minute, then turning it back on.
4. Clear outdoor unit obstructions like plants or debris to allow proper airflow.

Deciding Between Repair and Replacement

At Airight Cooling, Heating & Plumbing Inc., we provide honest recommendations to help you decide whether to repair or replace your system.

1. Age of the System – Units 12–15 years old may be better replaced to avoid frequent breakdowns.
2. Cost of the Repair – If repair costs reach 40–50% of a new system, replacement may be more economical.
3. Frequency of Breakdowns – Frequent repairs often justify upgrading to a new unit.
4. Energy Efficiency – Modern mini-splits can significantly reduce energy bills, making upgrades financially smart.

We provide detailed diagnostics and transparent estimates so you can make an informed decision for your home and budget.
