Ductless Mini-Split Repair in Burlington County, NJ

Do you repair ductless mini-splits?

Yes. Gibson Home Services repairs ductless mini-split systems of all major brands, subject to normal parts availability and serviceability. Every repair starts with a diagnosis, and you get a flat-rate price before work begins.

A mini-split is built differently from a central system. There is an outdoor unit connected by refrigerant lines and wiring to one or more indoor units mounted in the rooms they serve, with no ductwork in between. That means problems often show up in a single room, and the cause can be in that indoor unit, in the outdoor unit or in the connection between them.

Gibson is a locally owned residential HVAC company based in Delran and serving Burlington County since 2009. Owner Ken Gibson is an NJ Master HVACR contractor, License 19HC00370300, and the company is EPA certified, bonded and insured.

Why is my mini-split not cooling?

A mini-split that runs without cooling may have a dirty filter, a mode or remote setting issue, a blocked outdoor unit, an electrical or control fault, or a refrigerant problem. Testing is the only reliable way to tell.

Start with the simple checks. Confirm the remote or wall control is set to cool, not fan, dry or auto, and that the setpoint is below the room temperature. Make sure the remote has working batteries. Check whether the filters need cleaning, following your owner's manual for filter care. Look at the outdoor unit to see whether leaves, snow or stored items are blocking it.

If those are fine and the room is still warm, it is time for a diagnosis. Weak cooling from a refrigerant problem points to a leak somewhere in the system, and we look for the cause rather than simply adding refrigerant and leaving.

Why is my ductless unit leaking water?

Water dripping from an indoor mini-split unit usually means the condensate is not draining the way it should, often from a blocked drain line, a drain path problem or a unit that is not sitting level.

An indoor unit removes moisture from the air while it cools, and that water has to drain away. When it cannot, it can drip down the wall or onto the floor. Ice forming on the indoor coil and then melting can also cause dripping, which brings it back to airflow or refrigerant questions. Turn the unit off if water is reaching walls, floors or anything electrical, and call for service.

What does a mini-split error code mean?

An error code or a pattern of blinking lights is the system reporting a fault it has detected. The code narrows the search, but it is a starting point for diagnosis, not the answer by itself.

Codes and light patterns differ by manufacturer and model, and the same code can have more than one cause. It is useful to write the code down, or take a photo of the display, before you call. That gives us a head start. Please do not try to reset the system repeatedly or open the unit to chase the fault yourself.

Why is my mini-split making noise?

New buzzing, rattling, grinding, clicking or squealing from an indoor or outdoor unit usually points to a fan, a loose part, a motor or an electrical component. A change in sound is worth checking.

Mini-splits do make some normal operating sounds, such as a soft hum or the occasional click as the system changes modes. What is worth a call is a sound that is new, louder than usual or paired with weaker performance. Noting when it happens, at startup, while running or when it shuts off, helps with the diagnosis.

What should I avoid doing myself?

Do not touch refrigerant lines, connections or electrical parts, and do not open the indoor or outdoor unit. Those repairs need a licensed technician.

Refrigerant handling requires EPA certification and the right equipment, and the wiring between the outdoor and indoor units carries line voltage. Homeowner care is limited to the basics: checking the control settings, keeping filters clean as the manual describes and keeping the outdoor unit clear.

How does a ductless repair visit work?

We listen to what you have noticed, test the system to find the cause, explain it plainly and give you a flat-rate price for the repair. You decide whether to go ahead.

The standard non-member service fee is $125. Comfort Club members pay less: $79 for Bronze, $59 for Silver and $0 for Gold, and receive 10%, 15% or 20% off repairs depending on tier. You can compare the tiers on our Comfort Club page. Repairs carry a 90-day labor warranty from Gibson, and replacement parts carry the manufacturer part warranty as provided by the manufacturer.

We repair all major brands of ductless systems. Gibson installs Daikin and Fujitsu ductless equipment, but you do not need to have one of those brands for us to work on your system.

When is it time to replace a mini-split instead?

When a system has needed repeated repairs, parts are hard to get, or the repair cost is high relative to the system's age and condition, we will talk through repair versus replacement honestly.

There is no universal formula. We look at the repair history, the current repair cost, parts availability, how well the system has kept the room comfortable and your plans for the home. If replacement makes sense, the estimate is free, and our ductless installation and replacement page explains what is involved. If repairing is the reasonable choice, that is what we will recommend.

Ductless repair FAQs

Can you repair a mini-split brand you did not install?

Yes. We repair all major brands, subject to normal parts availability and serviceability.

Should I just add refrigerant if it is not cooling?

No. Low refrigerant means there is a leak. We look for the cause rather than adding refrigerant without finding where it is going.

One indoor unit works and another does not. Is that one problem?

It can be either. A fault in a single indoor unit is different from an outdoor unit or connection problem, which is why we test before recommending a repair.

Will I know the price before the repair?

Yes. Repairs use flat-rate pricing, and you approve the price before any repair work starts.
