There are a number of signs that indicate you need to call on a technician for ductless mini split repair services. Signs you need your mini split repaired include:

Ductless Mini Split Has Decreased Airflow

Poor airflow from your mini split can mean you simply need to clean or replace your air filter. However, it can also point to more serious issues. If the problem is not being caused by the air filter, get in touch with a technician who can come and check on what is going on. The problem could be an issue with the blower, or evaporator coils that have become clogged.

Mini Split Unit Smells Strange

Strange odors coming from your ductless mini split can be difficult to identify. Call a heating and cooling systems specialist when you notice strange odors when you turn your unit on. There could be mold or mildew growth within the mini split system, or something caught in the filter that is causing an odor. If you can’t seem to identify the issue, it is possible that something is going on with the system’s wiring, causing a burning odor.

Ductless Unit Isn’t Producing Cool Air

The refrigerant level is one of the first things to check when your ductless mini split is producing warm air instead of cold air. In order to properly check your refrigerant levels, get in touch with a trusted HVAC technician at Robinson Heating and Air Conditioning, Inc. Refrigerant is a toxic chemical that should only be handled by an HVAC professional. If refrigerant levels are fine, your technician can look at other parts of your ductless mini split to determine where the issue lies.

Energy Bills Are Climbing

Excessive utility bills should be investigated by a professional, as this is usually a sign that the ductless mini split system in your Middletown, OH, area home is not running efficiently. Look over the usage rate on your utility bill to see if you are using more energy than in previous months and years. If you are using more energy and are still not comfortable, it’s time to have your ductless mini split serviced.

Mini Split Is Loud and Making Strange Noises

Strange noises coming from your ductless mini split system should be investigated further by an HVAC specialist. Ductless mini splits are known for their quiet operation, and if your system is running louder than normal, or there is a strange sound coming from your unit, it’s time to call for a repair.

Ductless mini splits are versatile systems that handle both heating and cooling, providing year-round comfort. But like any system, they can experience issues from time to time. Here are some common repair problems we see with ductless mini splits and how our experts at Robinson Heating and Air Conditioning, Inc. quickly resolve them.

Low or No Cooling or Heating

If your ductless mini split isn’t heating or cooling effectively, it could be due to low refrigerant, a dirty air filter, or a malfunctioning compressor. We start by checking the refrigerant levels and recharging it if necessary. We also clean or replace air filters and check the compressor, ensuring it’s operating properly to restore the desired comfort in your home.

Odd Sounds From Your Ductless Mini Split

If you hear buzzing, rattling, or squealing sounds, it could be a sign of loose parts, obstructed airflow, or fan motor issues. Our team will inspect and tighten any loose parts, clear blockages, and lubricate the fan motor to eliminate the noise so your system runs quietly and smoothly.

Water Leaks From Your Mini Split

Water leaks can happen when the condensate drain gets clogged or if the coils freeze. This can occur during both heating and cooling modes. We’ll clean the condensate drain line, inspect for ice buildup, and check the refrigerant levels to prevent further issues. 

Your Ductless Mini Split Won’t Turn On

If your ductless mini split isn’t powering on, it could be caused by a blown fuse, a faulty remote, or issues with the circuit board. We will inspect the electrical components, replace any faulty parts, and get your system running again quickly, whether it’s for heating in the winter or cooling in the summer.

Your Mini Split Keeps Turning On and Off

Short cycling occurs when the system turns on and off repeatedly in a short period of time. This issue can be caused by refrigerant problems, electrical issues, or an oversized unit. We’ll assess your system’s overall performance and fix short cycling issues so that your ductless mini split can keep you comfortable without interruptions.
