Common ductless mini-split 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
Price Range: $200 – $1,500
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.

Upon initial contact, we promptly schedule an appointment for your AC repair and call you a day before the scheduled service, reconfirming the appointment and discussing any additional requirements.
2. No-Obligation Service Visit
Upon arrival our technician will find out about your AC concerns & find the issue at hand. Once the issue is found, he will discuss how to fix the issue, give you an estimate and ensure that you are included in the decision-making process.
3. Your Repair Feedback
Our team is always looking out for ways to grow. After performing your ductless mini split repair, we are all ears for your feedback. We guarantee full customer satisfaction and want to tend to any residual concerns.
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.
1. Are you licensed and insured?
A reputable service provider should have a valid state license and insurance. These are non-negotiable credentials that protect both the technician and you in case of any mishaps or accidents. Comfort One is licensed and bonded contractor by the State of Arizona (License #:308978)
2. Do you provide written estimates?
Transparency starts with a clear, written estimate that outlines labor costs, parts, and other fees. At Comfort One, we provide detailed and written estimates that leave no room for hidden charges. Before any of our AC repairs are started, we discuss the estimate with you and wait for your approval.
3. What kind of parts do you use?
The quality of parts used can drastically affect the longevity and efficiency of your AC system. Nowadays many parts are produced in China and do not come with any type of warranty. We recommend to look for services that use American quality parts, just like we do at Comfort One.
4. Are reviews and references available?
Customer reviews and testimonials give you insights into actual customer experiences. They help you understand if the AC repair service provider walks their talk. We are proud of our 100% customer satisfaction rate and openly share our customer reviews. Read our Google reviews here.
5. What’s your turnaround time?
When your AC is down, time is of the essence, especially in the Arizona heat. Check how promptly the service can attend to your needs. At Comfort One, we’re committed to being “On Time, Every Time!”. Some of our reviews even say ‘Jessica was the only one to actually answer the phone.’.
6. Do you offer a warranty?
A reliable service provider stands behind their work. Always inquire about warranty options for parts and labor. We protect all our AC repairs with robust warranty options, because your peace of mind is our commitment. We generally offer a 90-day labor warranty and 1-2 year warranty on parts under the premise ‘Love it or we fix it’.
