Expert Ductless Mini-Split Repair Services

Ductless mini-split systems are an excellent solution for homes without ductwork or for adding heating and cooling to specific rooms. However, like any HVAC system, they can encounter problems over time. If you’re experiencing issues with your mini-split system, our team has the expertise to diagnose and repair a wide range of problems, including:
Lack of Cooling or Heating: If your system isn’t providing the right temperature, it could be due to a refrigerant leak, faulty compressor, or electrical issue.
Unusual Noises: Humming, rattling, or banging sounds can indicate problems with the fan, motor, or other internal components.
Water Leaks: If water is leaking from your indoor unit, it’s often caused by a clogged drain line or a malfunctioning condensate pump.
Inconsistent Temperatures: If certain rooms aren’t reaching the desired temperature, there could be a problem with the thermostat, fan, or airflow.
Error Codes: Many ductless systems display error codes on their control panels. Our technicians can diagnose and resolve these codes quickly.

Common Ductless Mini-Split Problems We Repair

Ductless mini-split systems are known for their reliability and efficiency, but occasional issues can arise. Here are some common problems we fix:
Refrigerant Leaks: Refrigerant is essential for cooling and heating your home. If your mini-split is low on refrigerant, it won’t be able to maintain the desired temperature. Our technicians will check for leaks, repair them, and recharge the refrigerant to restore proper function.
Electrical Failures: A blown fuse, faulty wiring, or malfunctioning electrical component can prevent your system from turning on or operating correctly. We’ll inspect the electrical system to identify and repair any issues.
Frozen Coils: Frozen evaporator coils can prevent your mini-split from working efficiently. We’ll defrost the coils, check for airflow restrictions, and ensure the system is free from blockages.
Clogged Drain Lines: Condensation builds up in your system during normal operation. If the drain lines become clogged, it can cause water to back up and leak from the unit. We’ll clear the lines to prevent water damage and restore proper drainage.
Sensor and Thermostat Issues: If your system isn’t reaching the set temperature or turns off unexpectedly, there may be an issue with the thermostat or internal sensors. We’ll test these components and recalibrate or replace them as needed.
Signs Your Ductless Mini-Split Needs Repair

Not sure if your mini-split system needs professional attention? Here are some tell-tale signs it’s time to call in the experts:
Decreased Efficiency: If your energy bills are higher than usual, but your home isn’t staying as comfortable, it could indicate a problem with your system.
Unresponsive Controls: If your remote control or thermostat isn’t working properly, or your system isn’t responding to settings, it’s time for a repair.
Unpleasant Smells: Musty or burning smells coming from your mini-split system can signal a mold issue or electrical problem.
Frequent Cycling: If your system is turning on and off frequently, it could be an indication of a malfunctioning thermostat, refrigerant issues, or other underlying problems.
No Airflow: A complete lack of airflow is a sign of a serious issue, such as a broken fan motor or compressor failure.
When to Consider Replacing Your Mini-Split System
While repairs can often resolve issues and extend the life of your ductless mini-split, there comes a time when replacement might be more cost-effective. Consider replacing your system if:
Your mini-split is more than 10-15 years old.
Repair costs exceed the value of a new system.
Your system requires frequent repairs or isn’t performing efficiently.
At Thomas Home Services, we can help you decide whether it’s time to replace your system. If a replacement is necessary, we offer professional installation of high-efficiency ductless mini-split systems to keep your home comfortable year-round.
