AC Repair in Tulsa OK – 7 Common Mini Split Problems


A mini-split AC is an excellent investment for your home. It keeps you cool during the hot summer and provides excellent heating during winter. But, if your AC is not working as efficiently as it should be, it could be due to various reasons. Although don’t fret; from leaking refrigerant to frozen evaporator coils, we have got you covered.

Cartwright Heat & Air is the trusted name for mini-split AC repairs in Tulsa, OK. Our skilled professionals can diagnose and fix any issue with your mini-split AC. Here are seven common problems we see with mini-split ACs:

Leaking Refrigerant

If you notice hissing or bubbling sounds, warm air from your mini-split AC, or frozen coils, it could be due to leaking refrigerant. This issue can affect cooling efficiency and increase energy bills while compromising comfort levels.

It is essential to hire a licensed HVAC technician for refrigerant leak repair due to the associated health hazards. Schedule regular maintenance with us to prevent refrigerant leaks and enjoy cold air all year round.

Clogged Air Filter

Your system’s air filters keep your mini-split AC running smoothly. Over time, dust and debris can accumulate, leading to clogged filters. This issue can cause reduced airflow and put additional stress on the system.

Dirty filters can reduce airflow and cause wear on components, leading to expensive repairs or system failure. Prevent this by scheduling regular maintenance with licensed HVAC technicians who offer exceptional customer service in surrounding areas like Manhattan Beach, CA.

Faulty Compressor

The compressor is vital for maintaining the optimal performance of your mini-split AC. Signs of a faulty compressor include strange noises, reduced cooling power, and high energy bills. Lack of maintenance and electrical issues can lead to compressor failure, which requires professional help to repair or replace.

If you notice any of these symptoms, it is best to contact a licensed HVAC technician to diagnose and fix the issue before it causes further damage and leads to costly repairs.

Faulty Blower Motor

Your mini-split system has a blower motor that serves as the main engine for circulating cool air throughout your home. A faulty blower motor can cause uneven cooling and poor indoor air quality.

Regular maintenance is essential to keep your blower motor running efficiently. However, if you notice any strange noises or reduced airflow, it could be a sign of a damaged blower motor. Contact our licensed HVAC technicians to diagnose and repair the issue promptly.

Refrigerant Charge Imbalance

Refrigerant charge imbalance is a common problem with mini-split AC systems, leading to reduced cooling efficiency and increased energy bills. Signs of this issue include uneven cooling, ice buildup on the evaporator coil, and strange noises.

Regular maintenance and inspections are recommended to prevent such issues. Remember that refrigerants are dangerous to work with, so contact our licensed HVAC technicians to diagnose and repair the issue immediately.

Electrical Control Failure

To avoid breakdowns in mini split AC systems, hiring professional technicians for electrical control issues due to faulty wiring, damaged capacitors, or malfunctioning sensors is essential. For your safety, it is crucial not to attempt DIY repairs in these instances. Signs of electrical control failure include complete system failure, circuit breaker tripping, and strange noises.

Frozen Evaporator Coils

Air conditioners can experience frozen evaporator coils, reducing airflow and inefficient cooling. This issue is caused by improper airflow over the evaporator coil, dirty air filters, or a refrigerant leak.

You can prevent this issue by regularly cleaning and replacing air filters and scheduling routine maintenance with our licensed HVAC technicians. If you notice any signs of frozen evaporator coils, such as a buildup of ice on the coil or reduced cooling efficiency, call us immediately to diagnose and repair the issue. Don’t wait until it causes further damage to your mini-split AC system.

These are just a few of the common issues that can arise in your mini-split AC system. If you want to maintain optimal cooling efficiency and save on energy bills, it’s essential to stay vigilant for any signs of problems and schedule regular maintenance with our licensed technicians.

Reasons Why You Should Never Opt for DIY Repairs

DIY repairs for Mini-Split AC systems can have costly consequences that far outweigh any money saved from not hiring a professional technician. DIY repairs can be dangerous and often result in further damage to the system, leading to more expensive repairs or even the need for a complete unit replacement.

Here are some key reasons why you should never attempt DIY repairs on your mini-split AC system:

Inadequate Knowledge and Skill

Opting for DIY repairs without adequate knowledge and skill is not recommended as it may lead to serious consequences such as further damage, safety hazards, and even injury or death. It’s best to hire a licensed HVAC technician with the necessary tools, expertise, and exceptional customer service skills to diagnose and fix issues correctly.

Compromised Comfort Levels

Maintaining your ductless mini-split system is essential to avoid uncomfortable indoor temperatures and costly repairs. A licensed HVAC technician offering exceptional customer service can identify issues such as refrigerant leaks or coil mold while providing energy-efficient solutions.
