Mini-Split Repair in San Bernardino, CA — Book a Visit Today

Ductless heads that drip, blink an error code or blow air that never gets cold need diagnosis at the head and the outdoor unit both, and we do mini split repair across San Bernardino for converted garages, additions and older homes without ducts. Line set leaks, clogged condensate drains, failed control boards and dust-blocked filters cover most of what we find. Long cooling seasons here mean these units run far more hours than the brochure assumed. You can rinse the washable filters yourself. The rest involves refrigerant and high voltage, so call us or send the quote form.

Mini-Split Repair in San Bernardino — quick answers

Why is my mini-split leaking water inside the house?

Almost always a blocked condensate drain. Dust and biological growth build up in the drain line, water backs up in the pan, and the head either drips down the wall or shuts off on a float switch. We clear the line and clean the coil.

Can one zone be repaired without touching the others?

Often yes. If the fault sits in a single indoor head, its board or its branch of the line set, we repair that zone and leave the rest running. Faults in the outdoor unit affect every zone and need repair there.

What does a blinking light on the indoor unit mean?

It is an error code. Each manufacturer uses a different blink pattern to point at a sensor, a communication loss or a compressor fault. We read the code at the board, then verify it with pressure and amp readings before replacing anything.

My mini-split runs constantly and never reaches setpoint. Why?

Inverter systems are built to run long and low, so that alone is normal. Never reaching setpoint is not. Usually a dirty indoor coil, a low refrigerant charge from a loose flare fitting, or a compressor losing capacity.

How soon can you get to my house in San Bernardino?

Call us and we will give you a real window rather than a guess. During summer heat waves the same day slots fill early in the morning, so calling as soon as the AC stops blowing cold gives you the best shot. Before we arrive, check that the thermostat is set to cool with fresh batteries, look for a tripped breaker, change a clogged filter, and clear leaves and dust away from the outdoor unit. Sometimes that is the whole problem.

How it works

  1. Step 1

    Tell us the symptom

    Call or fill out the quote form. We ask what changed, when it started, and whether the outdoor unit is running. That tells us which parts and gauges to load on the truck before we leave.

  2. Step 2

    We diagnose on site

    We check the thermostat, the electrical side, airflow, refrigerant pressures, and the condenser coil. Desert dust plugs coils and dying capacitors are common. You get the finding in plain words before we touch a part.

  3. Step 3

    Repair and verify

    We make the repair, then run the system and measure supply air temperature and amp draw so we know it is actually cooling or heating. We tell you what we saw and what to watch for next season.

Why homeowners call us

  • We know rooftop unitsHalf the valley has a package unit on the roof, baking all summer. We are up there regularly, so we know how those cabinets fail, where the drain pans rust, and how heat and sun break down wiring and blower assemblies.
  • Dust is the local enemyFine desert dust mats onto condenser coils and chokes airflow, and the system runs hot until something gives up. We check the coil on every call and tell you honestly whether cleaning will fix your cooling problem.
  • July gets treated like JulyA dead condenser when it is 112 outside is not a routine call. We prioritise homes with no cooling, and we say clearly when we can be there instead of leaving you guessing all afternoon.
  • Heating tooDesert nights get cold and furnaces sit unused for months. We do heater repair and furnace repair, including no-ignition problems, bad igniters, and blowers that hum without moving air. Same straight explanation, no upsell speech.
  • All major brands, gas & electricIndependent service on Carrier, Trane, Lennox, Goodman, York and the rest.
  • Straight answersIf a system is not worth repairing, we say so, often right on the phone.
