A malfunctioning mini split can show a range of symptoms, and our experienced technicians at Infinity Heating & Air are prepared to handle them all. If you notice any of the following, it’s time to schedule service with a professional.
Your system may run but still fail to reach the desired temperature. Causes include low refrigerant from a leak, clogged filters restricting airflow, or a failing outdoor compressor unit.
Pooling water beneath your unit is often caused by a clogged condensate drain line or a cracked drain pan. Sometimes improper installation can also create this issue.
Mini splits are meant to operate quietly. Grinding can signal worn motor bearings, rattling often means loose parts or debris, and buzzing may point to electrical problems needing urgent repair.
Musty or sour smells usually result from mold or mildew on the coils or inside the unit. This affects both comfort and indoor air quality and requires professional cleaning.
Unresponsiveness may stem from simple causes such as a tripped breaker or a dead remote battery, but it can also involve more serious issues like a failed control board or wiring problem.
Short-cycling wastes energy, wears out the compressor, and raises bills. Common culprits include dirty filters, incorrect thermostat readings, or an oversized system.
At Infinity Heating & Air, we follow a precise and transparent process to ensure lasting repairs and customer confidence.
We thoroughly inspect refrigerant levels, electrical components, indoor and outdoor coils, thermostat accuracy, and the condensate drain to pinpoint the true cause of failure.
Our team explains the findings in simple terms, shows you the problem, and outlines recommended solutions with upfront details so you can make an informed decision.
Once approved, we perform the repair using high-quality parts and proven techniques—whether sealing leaks, replacing motors, or clearing clogged drains.
After completing the repair, we rigorously test the system to confirm proper heating, cooling, and airflow, ensuring it performs better than before.
