In a lot of Los Angeles homes, one machine handles both heat and cooling. A heat pump or a ductless mini split goes quiet on a cold night, and suddenly you have neither. Emergency HVAC repair covers exactly that: one technician, one visit, and a written price for getting the whole system running again. Phones are staffed 24/7 for Hollywood and the surrounding neighborhoods.
One dispatch for any system in the house
You should not have to figure out whether your problem is a heating call or a cooling call. Our dispatchers book it as one job and send a tech who works on all of it:
- Ducted heat pumps with an outdoor unit and an air handler inside.
- Single-zone and multi-zone ductless mini splits.
- Gas furnaces paired with a central AC on a shared blower.
- Hybrid setups, where a heat pump and a furnace share the work.
When you call, say which one you have, the brand if you know it, and any code blinking on the indoor unit or thermostat. That lets the dispatcher pick a truck with the right parts. You can also put those details into the emergency service request and we will call you back.
How an after-hours heat pump or mini split repair is priced
The price is written after the fault is found and before any work starts. What moves it:
| Factor | Effect on the price |
|---|---|
| The failed part | Sensors and capacitors cost less than a reversing valve, a board or a compressor |
| System type | Mini split boards and sensors are brand-specific; ducted parts are more common |
| Refrigerant work | Any leak repair needs recovery, a vacuum and a recharge |
| Access | Wall heads high on a stairwell and roof-mounted condensers take more time |
| Hour of the call | Late night and holiday dispatch carries its own rate |
If a single-zone ductless unit turns out not to be worth fixing, you get a replacement price on the same page. For reference, the site figure is that a single-zone system, one outdoor condenser, one indoor head, typically runs $3,400 to $5,700 installed, including compliance and startup.
Heat pump and mini split faults fixed on site
Many of these calls end with heat back the same night. The common ones:
- A failed defrost control or sensor, which leaves the outdoor coil packed with ice and the house cooling off.
- A stuck reversing valve, the part that switches the system between heat and cooling.
- A dead outdoor fan motor or capacitor.
- A fried control board after a power surge, more common on mini splits.
- A communication fault between the indoor head and the outdoor unit, often a loose or damaged wire.
Board and sensor parts for mini splits vary by brand. If the right one is not on the truck, the tech confirms the fault, writes the price and books the part. For a multi-zone system with one head down, the tech checks whether the other rooms can run while you wait, so the whole house is not cold.
When one dead blower takes out heat and cooling
A furnace and a central AC often share one indoor blower. If that blower motor or its capacitor fails, the furnace cannot push heat and the AC cannot push cool air. It looks like two problems. It is one repair.
The same goes for a burnt control board in the air handler or a failed transformer. The technician traces it back to the shared part, prices that one fix, and checks both sides of the system before leaving. If the cooling side has its own issue, it goes on the quote as a separate AC repair line you can accept or decline.
Mini split owners with an older system have one more decision. If the outdoor unit failed and the indoor heads are fine, the quote says whether the heads can stay. If the setup no longer fits the house, a new ductless mini split layout is priced next to the repair.
FAQ
Do you send someone after hours for a ductless mini split?
Yes. Mini splits get the same 24/7 dispatch as furnaces and central systems. Tell us the brand when you call so the truck carries matching parts where possible.
Is a heat pump stuck blowing cold air on heat mode an emergency?
If the house is getting cold and someone at home is vulnerable, yes. A reversing valve or defrost fault usually gets worse, so it is worth booking the visit that night.
Can you repair a system another company installed?
Yes. We diagnose and repair heat pumps and mini splits no matter who put them in. The written price comes before any work.
Will the visit cover the cooling side too?
The technician checks both heat and cooling before leaving. Anything found on the cooling side is priced as its own line, and you decide on it.
What if my system uses R-22?
R-22 is no longer produced, so any recharge uses reclaimed refrigerant and is priced as its own line. The tech also tells you whether repair still makes sense on that system.
