Some HVAC problems can wait until morning. Some can't. A complete AC failure during a heat advisory affects vulnerable family members — elderly, children, those with health conditions. A furnace failure on a cold night with temperatures in the 30s in the Valley is a genuine emergency. LC Heating & Air answers emergency calls 24 hours a day, 7 days a week, including holidays. We won't charge you triple rates — our emergency service fee is reasonable and disclosed upfront.
When your air conditioner quits during a 100-degree heat wave or your furnace stops working on a freezing night, you don't need a sales pitch—you need a technician who knows how to fix the equipment. I'm Leo, and at LC Heating & Air, we handle emergency calls differently. We don't use call centers or answering services that just take messages for the next business day. When you call (323) 970-3113, you get a licensed technician who can talk through your problem and get to your home.
We serve the entire Los Angeles area, from the heat-prone San Fernando Valley to the older neighborhoods where HVAC systems have been modified and patched over decades. We understand that when your system fails, it’s often a safety issue or a major health concern for your family. We show up with a truck stocked with the parts that actually break—capacitors, contactors, ignitors, and gas valves—so we can get you back up and running without unnecessary delays.

Why LA HVAC Systems Fail
Los Angeles has a unique set of challenges for HVAC equipment. We deal with extreme temperature swings, dust, and wildfire smoke that clogs filters and stresses components. In older homes, we often find systems that were shoehorned into tight attics or crawlspaces, leading to poor airflow and overheating. When these systems are pushed to their limit during a heat advisory, the most common failure points are electrical components like capacitors and contactors.
In the San Fernando Valley, where temperatures can be 15 degrees higher than the coast, we see a lot of systems running at 100% capacity for days on end. This constant strain causes wear on motors and compressors. Conversely, in the winter, we get calls for furnace failures in older homes where the gas valves or ignitors have finally given out. We don't just replace parts; we look at why the system failed in the first place to ensure the fix actually lasts.
Working with LA's Diverse Housing
Los Angeles housing is a mix of everything from pre-war bungalows to modern multifamily developments. Each type of building presents different challenges for HVAC repair. In older homes, we often deal with outdated electrical panels or ductwork that wasn't designed for modern high-efficiency units. If we are called out for an emergency, we have to look at the whole picture—the electrical, the duct condition, and the equipment placement—before we can safely recommend a repair.
We don't believe in 'one-size-fits-all' solutions. If your system is old and the repair cost is high, I will be the first to tell you that a replacement might be the smarter financial move. But if a simple capacitor swap gets you through the summer, that’s exactly what we’ll do. We prioritize honesty over upselling.
Our Emergency Diagnostic Process
When we arrive for an emergency, the first thing we do is ensure the home is safe. If there is a smell of gas or a carbon monoxide alarm sounding, we treat it as a life-safety event. We don't guess. We use proper testing equipment to verify the integrity of your heat exchanger and the safety of your gas lines.
Once the safety check is clear, we move to the diagnostic. We check the airflow, the electrical draw on the motors, and the refrigerant levels. We want to know why the system stopped. Is it a failed part, or is the system struggling because of a dirty coil or a restricted duct? By identifying the root cause, we can perform a repair that actually solves the problem rather than just putting a band-aid on it.
Repair or Replace?
This is the most common question I get at the kitchen table. If your system is relatively new and a specific part has failed, a repair is almost always the right choice. We carry the common parts to fix most AC and furnace failures on the spot.
However, if your system is 15-20 years old and the repair involves a major component like a compressor or a heat exchanger, we need to have a serious talk about replacement. Spending $800 to fix a system that is on its last legs is rarely a good investment. We will give you the facts so you can make the decision that makes sense for your budget and your home.
Transparent Pricing
I know that emergency service has a bad reputation for 'surprise' fees. At LC Heating & Air, we do things differently. We disclose our emergency service fee upfront when you call. We don't use after-hours or holiday multipliers to inflate the cost of the actual repair. You pay for the diagnostic and the repair, regardless of whether it's 2 PM on a Tuesday or 2 AM on a Sunday.
Our goal is to get your system stable. If a part needs to be ordered, we will get your system running as safely as possible for the night and return first thing in the morning to finish the job. We provide written estimates for all repairs so you know exactly what you are paying for before we start.
Getting Us to Your Door
When you call (323) 970-3113, you aren't talking to a call center in another state. You are talking to a technician. We give you an honest ETA based on our current location and traffic in the LA area. We know that when your AC is out in the middle of a heat wave, every minute counts.
We serve the entire Los Angeles area, and we are familiar with the access challenges of our city—from tight parking in Hollywood to attic access in older homes. We come prepared with the right tools and the right attitude to get the job done efficiently.
Mistakes to Avoid During an Emergency
The biggest mistake I see homeowners make is trying to 'fix' a gas leak or a CO alarm themselves. If your CO detector goes off, get everyone out of the house immediately. Do not try to find the source. Call 911, then call us. Another common mistake is ignoring a system that is struggling. If your AC is making a strange noise or your furnace is short-cycling, don't wait for it to die completely. A small repair now is almost always cheaper than a total system failure on a holiday weekend.
Also, don't be afraid to use temporary measures. If your AC is down during a heat advisory, go buy a portable unit or a window unit to keep one room cool for your family. It’s a smart, practical move while you wait for us to arrive.
Your Safety is Our Priority
HVAC systems involve high-voltage electricity, natural gas, and carbon monoxide. These are not DIY projects. When we respond to an emergency, we are looking for safety hazards first. If we find a cracked heat exchanger, we will shut the system down and explain why it is dangerous to run it. We don't take shortcuts with your family's safety.
We are fully licensed (CSLB #1073586) and insured, which means you don't have to worry about liability when we are working in your home. We treat your property with respect and we leave it as clean as we found it.
How We Help You Decide
When I’m at your house, I’m looking at the equipment the same way I would if it were in my own home. I’ll show you exactly what failed and why. If it’s a simple fix, we’ll do it. If the system is clearly nearing the end of its life, I’ll show you the signs—the rust, the age, the repair history—so you can make an informed choice.
My job isn't to sell you a new system; my job is to make sure your home is comfortable and safe. We provide the facts, the options, and the written estimate. You make the call.

What Los Angeles customers say about emergency hvac
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our emergency hvac service.
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
