What counts as emergency mini split repair?
An emergency is a problem that can hurt people or your home, or leave a vulnerable person in the heat. Sort what you see with this table.
| What you see | How urgent | What to do |
|---|---|---|
| Burning smell, smoke, sparks or loud buzzing | Emergency | Turn the unit off at the breaker and call us. If you see smoke or flames, call 911. |
| Breaker trips again after one reset | Emergency | Stop resetting it. Leave the unit off and call. |
| Water pouring from the indoor unit, or dripping near outlets or a ceiling | Emergency | Turn the unit off, then the breaker. Catch the water and call. |
| No cooling on a hot day with an older adult, a baby or someone with a health condition at home | Urgent | Move them somewhere cool and call for the earliest visit. |
| Ice on the indoor unit | Urgent | Switch to fan only, then call. |
| Blinking light that comes back after one power reset | Urgent | Photo of the pattern and model label, then call. |
| Weak airflow, small drip, musty smell, short cycling, uneven room temperatures | Book a visit | Rinse the filter first. Call for the next open slot. |
Is a mini split that stopped cooling an emergency?
It depends on the weather and who is home. On a mild day it can wait. On a hot afternoon it is urgent if an older adult, an infant or someone with a chronic health condition is at home, since the CDC lists those groups as higher risk in extreme heat. Check the remote mode and the filter first.
Why is my mini split covered in ice?
Ice on the indoor coil is always a fault. Filterbuy’s service guide traces it to two causes: too little airflow or too little refrigerant. A dirty filter is the usual airflow cause. Low refrigerant means a leak. Switch to fan only so the evaporator coil thaws, and never chip the ice.
What does a blinking light mean?
The unit found a fault. Each brand has its own code list, and one code can point to a sensor, a fan motor, a communication error or the control board. Take a photo of the pattern and the model label. Cut the power once, wait a few minutes and turn it back on. If the light returns, call.
Why is my mini split leaking water?
Most often the condensate drain is blocked. A frozen coil drips as it melts, and a failed drain pump can cause it too. If water drips near outlets or a ceiling, turn the unit off at the breaker.
Why does the breaker keep tripping?
A breaker trips to stop too much current. Common causes are a dirty filter, a dirty condenser coil, a loose connection, a short or a worn compressor. Reset it once. Aire Serv’s guide says to stop turning it back on if it keeps tripping, because something is wrong and needs fixing first.
Is it a refrigerant leak?
A mini split does not use up refrigerant, so cooling that fades over weeks usually means a leak. A tech finds it with a nitrogen pressure test or a vacuum decay test. Adding gas without fixing the leak only gives short relief.
Mini split repair emergency: what to do before we arrive
These steps are safe for any homeowner.
Turn the unit off at the remote. Use the breaker if you smell burning, see smoke, hear loud buzzing or see water near outlets.
If the breaker tripped, reset it one time only.
Check that the remote is set to cool or heat, not fan or dry, and that the batteries work.
Rinse the filter. Look at the outdoor unit, the condenser unit, for leaves, boxes or plants blocking airflow.
With ice on the coil, run fan only and set towels under the indoor unit.
Take a photo of the blink pattern and the model label. Note when the problem started.
On a hot day, close the blinds, run fans and rest in the coolest room. Take babies, older adults and anyone who feels unwell somewhere cooler.
Do not open panels, touch the refrigerant lines or spray water near the unit. Do not keep resetting a breaker.
How an emergency repair visit works
You call and describe it. Brand, model, blink pattern, and what you hear, see and smell.
We check the basics. Remote or thermostat, power, breaker, filter, drain line and airflow.
We read the error code and test the part. We test the sensor, capacitor, fan motor, drain pump and control board before replacing anything.
We test for a leak when signs point to one. That means a nitrogen pressure test, then a deep vacuum and a recharge after the repair.
You get the price before work starts. You get a written estimate and upfront pricing.
We fix it and test it. We run cooling and heating and check drainage and airflow before we leave.
A diagnostic fee of $89 applies, and it is credited toward the repair if you approve the work. Emergency calls outside our 7 AM to 9 PM hours carry a flat $75 after hours fee.
What changes the price
- The failed part: a drain clean, a sensor, a capacitor, a fan motor, a control board or an inverter driven compressor.
- The brand, and whether the part is on hand.
- Where a leak sits. A flare connection is simpler than a hidden line set.
- Access. A tight ADU wall, a second floor unit or a hillside outdoor unit takes longer.
- The time of day, since emergency calls outside 7 AM to 9 PM carry a $75 fee.
Most repairs cost between $150 and $1,200.
| Fee | What it covers |
|---|---|
| Diagnostic visit: $89 | Credited toward the repair if you approve the work. |
| After hours fee: $75 flat | For emergency calls outside 7 AM to 9 PM hours. |
| Most repairs: $150 to $1,200 | Depends on the part and the brand. You get the price before work starts. |

What typical emergency calls look like
These are common call types, not customer stories.
Blocked drain in a Fairgrove Eichler
Water drips from the indoor unit onto the hallway floor. The home has a post and beam roof and no attic, so the leak shows fast. We clear the condensate line, flush it, test the drain pump and run the unit to confirm it drains. Most drain calls take about an hour.
Capacitor failure in a garage conversion
On a hot afternoon the outdoor unit hums but the fan will not turn. A failed capacitor is a common cause. We test it, swap it and check the amp draw before we leave. This is usually a one visit repair.
Tripping breaker in an ADU
The breaker trips each time the unit starts. We stop resetting it and test the outdoor unit for a loose wire, a dirty coil or a worn compressor. You get the price before any parts are replaced.
Why a dead mini split hurts more in Cupertino homes
Cupertino has about 260 sunny days a year, with dry summers and most rain in winter.
Some Cupertino homes have no attic. The Fairgrove tract has roughly 220 Eichler homes built in 1960 and 1961, with post and beam roofs and no attic, per the Eichler Homes For Sale guide. With no attic for ducts, a mini split is often the simplest way to add cooling. The same is true for ADUs, converted garages and home offices that the main system does not reach.

How long does a mini split repair take?
