Common Heating & Cooling ductless mini split AC repairs and their estimated costs

1. Refrigerant leaks

Price Range: $150 – $700


If your ductless mini-split is not cooling efficiently or you notice icing on the evaporator coils, you might be dealing with a refrigerant leak. Prices vary based on the complexity of the repair and the amount of refrigerant required.

2. Electronic control failure

Price Range: $100 – $800


When your remote control doesn’t interact with the indoor unit, it could be an electronic control failure. This problem is generally a straightforward fix but can cost more if the whole board needs to be replaced.

3. Motor or fan issues

The fans are integral for air circulation. If they aren’t working as they should, you’ll notice a decrease in system efficiency. Depending on the problem, you might need a simple repair or a whole new motor.

4. Drainage problems

Price Range: $100 – $450


In humid conditions, the drain lines can get clogged, causing water to leak from the indoor unit. Clearing a clogged drain is usually less expensive, but prices can increase if there are complications.

5. Sensor issues

Price Range: $75 – $200

If your unit is not maintaining the set temperature, the sensor might be at fault. The repair typically involves adjusting or replacing the temperature sensor located in the indoor unit.

6. Inadequate cooling

Price Range: $100 – $600


Several issues, from dirty air filters to blocked vents, could cause inadequate cooling. After a thorough diagnostic, our technicians can provide a precise estimate.

Integrity, Transparency & Honesty: The cornerstones of a reputable ductless mini-split repair service

Before you commit to a service provider, ensure that their practices are aligned with these three pillars. Below are the questions you should be asking.

Yes, we offer hvac maintenance to keep your ductless mini-split system operating at peak efficiency. Regular maintenance can help prevent many common issues and extend the lifespan of your unit.

Ductless mini-split systems offer several advantages over traditional central heating systems. Firstly, they are more energy-efficient since they do not rely on ducts, which can lead to significant heating loss. This efficiency can lead to lower energy bills and therefor your heating becomes more expensive.

Secondly, they allow for zoned heating, meaning different areas of a home can receive different heating temperatures, enhancing comfort and further improving energy savings.

Additionally, mini-split systems are generally easier and less invasive to install, especially in homes without existing ductwork. They also tend to operate more quietly and offer improved air quality as there is less potential for dust and allergens to circulate through ducts.

Hence ductless mini split systems offer many advantages for heating and cooling.

Common signs that a ductless mini-split heating system needs repair include unusual noises during operation such as grinding or hissing sounds which can indicate mechanical problems or refrigerant leaks.

If the system is not heating effectively or there are noticeable fluctuations in temperature, this could signify issues with the thermostat or internal components.

Additionally, any visible ice build-up on the coils, water leaks around the mini split unit, or strange odors when the system is running are red flags.

When these signs are observed, it's advisable for the homeowner to contact a professional HVAC technician for a thorough inspection and repair, rather than attempting DIY fixes, to ensure the heating system is properly and safely repaired.

Routine maintenance of your HVAC systems and mini-split air conditioning system involves several key steps to ensure its optimal performance and longevity. These include:

  1. Cleaning or Replacing Air Filters: Regularly cleaning or replacing the air filters is crucial to maintain airflow and efficiency. Clogged filters can strain the system and reduce its effectiveness.
  2. Cleaning the Exterior Unit: The outdoor unit should be kept clear of debris, leaves, and dirt. Ensuring good airflow around the unit is important for efficient operation.
  3. Inspecting and Cleaning the Coils: The evaporator and condenser coils should be inspected and cleaned periodically to prevent dirt and grime build-up, which can impede heat transfer.
  4. Checking Refrigerant Levels: Low refrigerant levels can indicate leaks and will affect the cooling performance of the system.
  5. Inspecting Electrical Components: Regularly checking the wiring and connections for signs of wear or damage can prevent electrical issues.
  6. Cleaning the Condensate Drain: The condensate drain should be checked and cleaned to prevent clogs, which can lead to water leakage and humidity problems inside the home.

By following these maintenance steps, homeowners can help ensure their mini-split AC system operates efficiently and has a prolonged service life.

Homeowners can identify the need for professional maintenance or servicing of their ductless air conditioners by observing several signs. Common issues that require expert attention include:

  1. Inconsistent Cooling: If the AC is not cooling as effectively as it used to or there are noticeable temperature variations, it might indicate a problem that needs professional diagnosis.
  2. Strange Noises: Unusual sounds like grinding, buzzing, or whistling from the unit can indicate mechanical problems or refrigerant issues.
  3. Unpleasant Odors: Musty or burning smells could signal mold growth in the unit or electrical problems, respectively.
  4. Visible Leaks: Water or refrigerant leaking from the unit is a clear sign that professional service is needed.
  5. Frequent Cycling: If the AC turns on and off more frequently than normal, it could suggest problems with the thermostat or the system’s internal components.

In such cases, homeowners should contact a qualified HVAC technician for a detailed inspection, maintenance and/or repair, as these issues can be complex and often require specialized knowledge and tools to address effectively.

Ductless mini-split systems can have a positive impact on indoor air quality compared to traditional HVAC systems, primarily due to their design and operational features. Unlike traditional systems that circulate air through ducts, ductless systems deliver air directly into each zone, reducing the potential for dust, allergens, and mold spores to accumulate and spread through ductwork.

Many mini-splits are equipped with advanced filtration systems that are more effective at trapping and removing airborne particles that are within the air. These filters can capture dust, pollen, bacteria, and other pollutants, significantly improving air quality. Additionally, some models come with built-in dehumidification functions, which help in controlling humidity levels in the air at home, thereby reducing the risk of mold and mildew growth.

Overall, the direct air delivery system, advanced filtration capabilities, and humidity control features of ductless mini-splits contribute to a cleaner, healthier indoor air environment.

To ensure optimal indoor air quality with ductless mini-split systems, homeowners should undertake the following maintenance steps:

  1. Regular Filter Cleaning or Replacement: Clean or replace the air filters every 1-3 months, or as recommended by the manufacturer. Dirty filters can restrict airflow and lead to the circulation of dust and allergens.

  2. Clean the Air Handling Units: Dust and wipe down the indoor units regularly to prevent the build-up of dust and dirt.

  3. Inspect and Clean the Outdoor Unit: Ensure the outdoor unit is free from leaves, dirt, and debris, as blockages can affect air quality and system efficiency.

  4. Check and Clean the Condensate Drain Line: Regularly inspect the drain line for clogs or blockages to prevent water accumulation and potential mold growth.

  5. Schedule Professional Maintenance: Have a professional HVAC technician inspect and service the system at least once a year. They can perform deep cleaning, check for refrigerant leaks, and ensure all components are functioning properly.

These maintenance steps should be performed regularly as part of a proactive approach to maintaining indoor air quality and the efficient operation of the ductless mini-split system.
