Signs Your Ductless Mini-Split Needs Repair
Performance changes may appear at one indoor unit or affect the entire system. Because similar symptoms can have different causes, the equipment needs to be checked before a repair can be recommended. A professional assessment is appropriate when a problem continues or returns after basic filter and power checks.
Common warning signs include:
- Poor Heating or Cooling: The system runs but doesn’t bring the room to the selected temperature.
- Water Leaks: Water drips or collects around an indoor mini-split unit.
- Error Codes: A displayed code or communication issue prevents normal operation through the system controls.
- Unusual Noises: New rattling, buzzing, grinding, or other unfamiliar sounds occur during operation.
- Weak Airflow or Odors: Airflow drops noticeably, or a persistent strange odor comes from the indoor unit.
- Suspected Refrigerant Leaks: Signs of refrigerant loss require diagnosis and service from a qualified HVAC technician.

Owner Oversight & Clear Ductless Repair Pricing
We’ve served Winston-Salem and surrounding communities since 2007. As a family-owned business, we have Brad or Gina personally present at every job site, giving homeowners a direct point of accountability while our technicians evaluate the equipment.
Repair cost depends on the diagnostic findings, the affected component, required parts, and labor. We provide transparent pricing so you can review the recommendation before authorizing the work.
Flexible scheduling and weekend service availability make it easier to arrange a visit around household commitments. If the findings lead you to consider system replacement, we provide free estimates for new equipment. Free estimates apply to new equipment, not repair diagnostics or repair estimates.

"I'll certainly call upon them again whenever there's a problem in the future"
I had problem with my cooling system which was caused by the negligent work of the previous company that I had hired. Apparently, system malpractice is not rare nowadays. All-Phase sent over Evan to rescue us from our air conditioning meltdown. He was a young fellow, but sharp as a tack. He had an aire of professionalism and respectfulness which has become uncommon, as if he had stepped out of the 1950s. The reason I picked the company was because the website made it appear as if were operated by a good family. They looked trustworthy. I wasn't disappointed in my decision. My expectations were exceeded. There was basically a thicket that had grown up around the outside unit, so he had to fight his way through it, in order to get the job done. There was not one complaint. He did the job fast and well, while maintaining a positive attitude the whole time. Even the dog liked him, and "killer" doesn't like anybody. When everything was finally completed, I was pleasantly surprised by the charge. It doesn't seem proper to site numbers, but it was very reasonable, and considerably less than what I was accustomed to. I'll certainly call upon them again whenever there's a problem in the future.

Highly recommend this team for your heating and AC needs. I have been a customer for almost 5 years now and I am enrolled in a maintenance plan (every customer should enroll in this).

"Overall, it’s a great company with great morals and values that shine through the respectful treating of their customers."
I had a great experience! Ask for Evan. He came out promptly, diagnosed my heat pump quickly and came back the next day to fix it. In the process, I learned a lot about how heat pumps work. He really took the time to explain things. Would highly recommend!

"We have used ALL Phase for years to maintain our units and appreciate their great service and integrity."
The All-Phase crew showed up as scheduled and handled the removal of our old HVAC unit and installation of the new unit efficiently. They completed the job easily within one day. The crew was respectful of our home and took time to cover and protect our stairs and floors. Everything was cleaned up nicely before they left. Additionally, the office staff were very helpful.

What to Expect During Ductless Repair Service
The process starts with a description of what the system is doing differently. Details such as when the problem began, whether it affects one indoor air handler, and any recent changes in performance give the technician useful context.
A typical ductless repair visit includes:
- System Assessment: A technician checks the system to identify the cause of the reported symptom rather than relying on the symptom alone.
- Repair Recommendation: The diagnostic findings guide the recommended work, which you can review before authorizing the repair.
- Equipment Considerations: The system’s brand, model, age, parts availability, and diagnostic findings determine the available repair options.
We answer questions about the findings and explain the proposed work so you can make an informed decision about your system.
