24/7 Emergency Heater, AC & Electrical Repair in Orange County
Calls Answered 24/7 · Same-Day Service in Most Cases
The heater quit on a cold night, the AC stopped cooling in the middle of a hot spell, or something in the electrical panel smells hot. Call (714) 499-6656 and you'll reach us, day or night, including weekends. A real person answers. Same-day service is available too: call early and in most cases we get to you today. We are a licensed heating, air conditioning and electrical contractor based in Fountain Valley, so one visit covers the furnace, the AC, the heat pump and the wiring that feeds them. Below you will find what to check safely while you wait, what to do first if you smell gas or a carbon monoxide alarm goes off, and what a repair usually costs.

Safety first: when to call 911 or the gas company before you call us
- You smell gas (a rotten-egg smell). Leave the house now. Do not flip switches or use the phone inside. From outside, call the gas company or 911.
- A carbon monoxide alarm is sounding. Get everyone, pets included, outside into fresh air and call 911. Carbon monoxide has no smell, so trust the alarm.
- You see smoke, flames or sparks from an outlet, panel or appliance, or the burning smell keeps getting stronger. Get out and call 911.
- Someone is unwell from heat or cold: confused, faint, very hot or very cold to the touch. Call 911 for the person first. The house can wait.
Once everyone is safe, call us. We fix what caused it.
Emergency heating, AC and electrical repair, answered 24/7
Most people who land on this page have one of three problems: no heat, no cooling, or something electrical that looks or smells wrong. We handle all three. Aerosphere Electric holds a California C-20 licence for heating and air conditioning (what the trade calls HVAC) and a C-10 licence for electrical work, CSLB #1108650. You can check it yourself at cslb.ca.gov in under a minute.
That second licence matters in an emergency. An AC that trips its breaker can be a cooling fault, a wiring fault, or both, and one visit checks both sides.
Same-day service is available: call early and we will get to you today in most cases. Emergency calls are answered 24/7: call and you'll reach us, day or night, including weekends.
Call (714) 499-6656What happens when you call
- A person answers and asks a few questions. Nights and weekends included. What stopped working, what you are seeing or hearing, how old the equipment is if you know, and whether anyone at home is elderly, very young, or has a medical need. We tell you the diagnostic fee, and whether after-hours rates apply, before anyone drives out.
- A technician comes out and finds the cause. We let you know when the technician is on the way. On site we test, not guess: the thermostat, the power supply, the safeties, and the part that actually failed.
- You get a clear price and decide. Nothing is fixed until you approve it. Most repairs are finished on that first visit. If the problem is bigger than a repair, we say so plainly and leave you a written estimate to think over.
Honest arrival times
We do not promise a set number of minutes. Same-day is realistic in most cases when you call early, and the emergency service areas list further down shows roughly how far each city is from our shop.
Parts on the truck, so most repairs finish on the first visit
The parts that fail most often travel with us: capacitors, contactors, furnace igniters, flame sensors, float switches and common condenser fan motors. Those cover a large share of emergency calls. A model-specific part, such as a particular inducer or blower motor, sometimes has to be ordered. When that happens we tell you how long it should take before we leave, and we make the system safe in the meantime.
Emergency heater repair: five safe checks before you call
A no heat emergency on a cold night is stressful, and sometimes the fix takes thirty seconds. These checks are safe for anyone, and trying them first can save you the cost of a visit.
- Thermostat. Is it set to Heat, not Cool or Off? Is the set temperature above the room temperature? If the screen is blank, replace the batteries.
- Breaker. Look in the electrical panel for a breaker marked furnace, heater or air handler that has moved to the middle or off position. Switch it fully off, then on, once. If it trips again, leave it off and call us.
- Furnace switch. Near the furnace (garage, closet or attic) there is usually a switch that looks like a light switch. It is easy to knock off by accident. Make sure it is on.
- Filter. A filter packed with dust starves the furnace of air, and it shuts itself off to protect itself. If yours is grey and clogged, replace it.
- Gas valve. The handle on the gas line to the furnace should run in line with the pipe. If it is across the pipe, it is closed. Only open it if you have no gas smell at all.
Any smell of gas: stop. Leave the house and call the gas company or 911 from outside before you do anything else.
Furnace not working after all five checks? The usual suspects are an igniter or flame sensor (the furnace clicks, tries to light, then gives up), an inducer motor (a whine or rattle, then nothing), or a blower motor (the burners light but little air comes out). All three are routine emergency furnace repair jobs for us. When the part is on the truck, that means same-day heater repair; when it has to be ordered, we tell you how long before we leave. Our page on furnace repair in Orange County goes into each one.
Heat pump blowing cold air in heat mode
A heat pump heats and cools with the same equipment, so it is worth knowing what normal looks like. On a cold, damp morning the outdoor unit runs a defrost cycle: the fan outside stops, you may see steam, and the air indoors feels cool for a few minutes. That is normal. What is not normal is cool air for more than 10 to 15 minutes, or an outdoor unit that sits silent. Check the thermostat is on Heat, then call. Likely causes include a failed capacitor or contactor, a stuck reversing valve (the part that switches between heating and cooling), low refrigerant, or backup heat strips that have stopped working.
Carbon monoxide alarm
Get out first and call 911. Do not stop to check the furnace. Once the fire department says the house is safe, call us. A cracked heat exchanger (the metal wall between the flame and your air), a blocked flue or a failing burner can all produce carbon monoxide, and we test for each. If the furnace is unsafe, it stays off until it is fixed or replaced, and we explain exactly why.
While you wait for heat, never use a gas oven, a barbecue or a generator indoors to warm the house. Plug a space heater straight into a wall outlet, not a power strip or extension cord, and keep it about three feet from bedding and curtains.
Emergency AC repair: AC not cooling or the coil is frozen
When the air coming out of the vents is warm, or barely cool, start at the thermostat: Cool mode, a set point below room temperature, fresh batteries. Then look at the lines on the outdoor unit and the indoor coil. If you see ice or frost on the copper pipes, the coil has frozen.
- Turn the cooling off at the thermostat and leave it off. Setting the fan to On (not Auto) helps the ice melt faster. It can take a few hours. Do not chip at the ice.
- Check the filter. A clogged filter is one of the most common reasons a coil freezes.
- Check the float switch. Many systems have a small safety switch in the drain pan or drain line that shuts the AC off when water backs up. If the pan under the indoor unit is full of water, that is probably why the AC stopped. It is a sign of a blocked drain, not a dead system.
- Listen outside. If the indoor fan runs but the outdoor unit is silent, or it hums without the fan turning, switch it off and call. That points to a capacitor or contactor, and running it that way can damage the compressor.
Same day AC repair is the norm for these faults, because the parts are on the truck. A coil that keeps freezing after a clean filter usually means low refrigerant from a leak, which takes longer to find and fix properly. We look for the leak rather than just topping it up. We are EPA 608 certified to handle refrigerant. More on common cooling faults is on our AC repair page.
Call (714) 499-6656Electrical emergencies: an emergency electrician in Orange County
Electrical trouble is where calm, quick action matters most. Call 911 if you see smoke, flames or sparks that keep going. For the situations below, keep people away, do not open the panel cover, and call us.
- Burning or hot-plastic smell near an outlet, switch or the panel. If you know which breaker feeds it, switch that breaker off.
- A panel that is hot to the touch or buzzing. A worn breaker or a loose connection can overheat. Stay back from it and call.
- An outlet that sparked, is scorched, or feels warm. Stop using it and switch off its breaker.
- Partial power loss, where half the house is dead or lights dim and brighten on their own. Check with your electric utility first for an outage on their side. If there is none, call us: this can be a loose main connection and needs a look the same day.
- A breaker that refuses to reset or trips again straight away. Leave it off. Forcing it on repeatedly heats the wiring.
Our C-10 electrical licence means the repair is ours to do, not a referral. If the cause is a single breaker, we replace it. If the panel is at its limit, worn out, or one of the older brands that electricians distrust, the next step is a replacement or an upgrade to a 200-amp panel, and that step is ours too. Where a whole-panel upgrade is more than the house needs, a subpanel or a new dedicated circuit for the AC or heat pump is often the simpler route.
Who is most at risk when the heating or cooling stops
For most healthy adults, a night without heat or an afternoon without AC is uncomfortable, not dangerous. For some people it is more serious, and it helps us to know when you call.
- Older adults, who can overheat or get chilled without noticing it happening.
- Babies and young children, who lose and gain heat faster than adults.
- Anyone with a heart, lung or other medical condition, or who relies on powered medical equipment such as an oxygen concentrator.
In the heat, keep them in the coolest room, draw the blinds, offer water often, and use fans. In the cold, add layers and blankets and keep them in one warm room. If staying with a relative or neighbour for the night is easy, that is a sensible choice. If anyone becomes confused, faint or unwell, call 911 first.
What an emergency repair costs in 2026
Clear pricing, three rules. The diagnostic fee is applied to the repair if you go ahead. You approve the price before any work starts. After-hours rates may apply; we tell you before we come. These are the typical ranges for the repairs we see most on emergency calls:
| Repair | Typical Cost | What it usually looks like |
|---|---|---|
| Diagnostic / service call | $89 – $150 | Applied to the repair when you go ahead |
| Run or dual-run capacitor | $200 – $400 | Outdoor unit hums, fan outside sits still |
| Contactor | $180 – $350 | Indoor fan runs, outdoor unit completely silent |
| Furnace igniter or flame sensor | $200 – $450 | Clicks, tries to light, then gives up; the classic first-cold-night call |
| Inducer motor | $450 – $950 | Whine or rattle at start-up, then no flame |
| Blower motor (standard PSC type) | $450 – $900 | Heat or cooling running, but little air at the vents |
| Condensate drain / float switch | $150 – $350 | AC shut itself off, water standing in the pan |
| Refrigerant leak search & repair | $350 – $1,500 | Frozen coil or slowly weakening cooling; wide range because leaks vary |
Typical 2026 ranges for Orange County homes at standard hours. Your exact price is given, and approved by you, before work starts. After-hours rates may apply and are stated before we come. We do not service water heaters or tankless water heaters of any brand.
We accept credit card, check, Zelle and cash. For larger repairs and replacements, 0% financing on approved credit is available.
When an emergency repair becomes a replacement conversation
Most emergency calls end with a repair and a working system. Some do not, and we would rather tell you straight than sell you a string of repairs on worn-out equipment. Nobody has to decide anything on a cold night.
Signs it may be time to replace rather than repair
- A cracked heat exchanger in a furnace. This is a safety issue, and the furnace should stay off. See furnace installation.
- An AC past about fifteen years old that needs a compressor, a coil or a large refrigerant repair. See AC replacement in Orange County.
- An older system still on R-22 refrigerant, which is no longer made and has become expensive to top up.
- You want heating and cooling from one efficient system. A heat pump heats and cools, and can replace both an old furnace and an old AC.
- The panel keeps causing trouble or has no room left for new equipment. An electrical panel upgrade solves it, and we do that work ourselves.
If you choose to replace, you get a free written estimate, and the price is agreed in writing before work starts. We pull the permit under our own licence and handle the Title 24 testing California requires. Utility and state heat pump incentives change often, so we check what currently applies at your address rather than quoting a figure from memory. If a repair makes more sense, we will tell you that too.
Refrigerant work is done under EPA 608 certification. You can read more about our technicians and their certifications.
Emergency repair questions, answered plainly
If I call at 2 a.m. or on a Sunday, will anyone actually answer?
Yes. Call (714) 499-6656 and you'll reach us, day or night, including weekends, and a real person answers. We ask what is happening, check first that nobody is in danger, and tell you the diagnostic fee and any after-hours rate before anything is booked. Then we give you an honest plan. Sometimes that is a visit tonight. Sometimes, if the house is safe and everyone is warm or cool enough, it is a simple step to get you through the night and an early visit in the morning. You choose, knowing the price.
How fast can you get to me?
It depends on when you call and where you are. Call in the morning and, in most cases, we reach you the same day. From our Fountain Valley shop, west county cities are roughly ten to fifteen minutes away, north county twenty to thirty, and south county thirty to forty, plus traffic. We do not promise a number of minutes. We give you an honest window instead, and if it is late in the evening we tell you whether tonight or first thing tomorrow is realistic, so you can decide.
How much does emergency heater repair or AC repair cost?
The diagnostic visit is $89 to $150, and that fee is applied to the repair if you go ahead. Most common repairs land between about $150 and $950: a float switch, capacitor, contactor, igniter or flame sensor at the lower end, an inducer or blower motor higher up. Refrigerant leak repairs vary more, from $350 to $1,500. After-hours rates may apply; we tell you before we come. Either way, you approve the price before any work starts, and there are no surprises on the invoice.
My breaker trips every time the AC starts. Is the electrical panel the problem?
Sometimes the breaker is doing its job and the AC has a fault, such as a failing capacitor or a compressor struggling to start. Sometimes the breaker itself is worn, or the circuit is undersized, or the panel is simply full. Because we hold both a C-20 heating and cooling licence and a C-10 electrical licence, we test both sides in one visit. If the panel turns out to be the weak link, the fix is ours too: a new breaker, a dedicated circuit, a subpanel, or an upgrade to a 200-amp panel.
Can you give me a price over the phone?
For a repair, no, because we have not seen the problem yet, and a phone guess is often wrong in one direction or the other. What we can tell you on the phone is the diagnostic fee and whether after-hours rates apply. Once the technician finds the fault, you get a clear price and decide. For a replacement, we give you a free written estimate after measuring the house, and that written price is the one you pay.
My system is old. Should I repair it or replace it now?
If the repair is modest and the rest of the system is sound, repairing it is usually the sensible move, even on an older unit. Replacement starts to make sense when a big repair lands on a system that is already near the end of its life: an AC or heat pump past about fifteen years, a furnace past about twenty, or a cracked heat exchanger at any age. We can get you running today where that is safe, then give you a written replacement estimate to think over, with no deadline.
Do you handle heat pump and mini-split emergencies?
Yes. A heat pump heats and cools, so when it fails you lose both, and we treat that as urgent in winter and summer alike. We work on ducted heat pumps, ductless mini-splits and the backup heat strips in the air handler. Common emergency faults are a stuck defrost cycle, a failed capacitor or contactor outside, a tripped float switch indoors, and heat strips that have stopped working.
I am arranging help for my mother. Can I set up the visit for her?
Yes, and it is a common call. Give us her address, the best phone number to reach her, and yours. Tell us about anything that matters for the visit: a gate code, a dog, or a medical need that makes the heat or cold more serious. The technician explains the problem and the price before starting, and you are welcome to be on the phone for that conversation. We take credit card, check, Zelle and cash.
Emergency service areas
Every call starts from our shop on Newhope Street in Fountain Valley. These times are rough, with clear roads. Rush hour on the 405, the 22 or the 5 adds to them; late at night the roads are quieter, but we still give you a window rather than a promise.
- Fountain Valley: about 5 to 10 minutes. Home base.
- Westminster and Costa Mesa: about 10 minutes.
- Garden Grove: about 12 minutes.
- Emergency AC repair and furnace repair in Santa Ana: Santa Ana shares a border with Fountain Valley, so it is one of our shorter drives, though the far side of the city takes longer.
- Emergency AC repair in Stanton: about 15 minutes, as are Seal Beach, Los Alamitos and Newport Beach.
- Emergency AC repair and furnace repair in Anaheim: about 20 minutes, the same as Orange and Buena Park. Anaheim has its own city electric utility, so during a power problem there, check with Anaheim Public Utilities for an outage before calling us.
- Fullerton, Lake Forest and Laguna Hills: about 25 minutes. South county, from Laguna Niguel and San Juan Capistrano (about 30) to Dana Point (about 35) and San Clemente (about 40), takes longer, and we tell you so up front.
Wherever you are in the county, 24 hour AC repair and 24 hour furnace repair calls are answered around the clock, and the same goes for electrical emergencies. For non-urgent work, request a free estimate online, or ask about 0% financing on approved credit.
