Emergency HVAC Service
Las Vegas — Both Seasons
No cooling in July or no heat in January — both are emergencies in this climate. Call and tell us what is happening and we will get a technician out to you.
Three Situations Where You Should Not Call Us First
We would rather lose the call than have you spend four minutes on hold during one of these. All three take priority over any HVAC problem.
You Smell Gas Or Rotten Eggs
Do not switch anything on or off. Do not use light switches, phones, or garage door openers inside the house. Get everyone out, then call Southwest Gas or 911 from outside.
Call us afterwards, once the property has been made safe. We will handle the furnace side once the gas company has cleared it.
Leave the house · Call 911 from outsideA Carbon Monoxide Detector Is Sounding
Get everyone outside into fresh air immediately and call 911. Carbon monoxide is colourless and odourless, and a cracked heat exchanger — the most common furnace-related source — gives no warning without an inspection.
Take it just as seriously if people in the house have headaches, nausea, dizziness, or drowsiness that improve when they step outside, even with no alarm sounding.
Everyone outside · Call 911There Is Smoke, Burning Plastic, Or Visible Scorching
Shut the system off at the breaker and leave it off. An electrical or acrid burning smell is not the normal first-use dust smell, and a system that keeps tripping its breaker is warning you about something.
If there is visible smoke or flame, get out and call 911. If it is a smell and a dead breaker, kill the power and then call us.
Breaker off · 911 if there is smokeEmergency HVAC Service In Las Vegas, For Both Seasons
Las Vegas is one of the few places where a heating failure and a cooling failure are both genuinely dangerous rather than merely uncomfortable. A house without air conditioning during a 112° week becomes unsafe within hours for older adults, small children, and anyone with a heart or respiratory condition. A house without heat during a January cold snap is a slower problem, but it is the same category of problem.
So emergency HVAC service in Las Vegas has to mean both. We take no-cool calls through the summer and no-heat calls through the winter, seven days a week, and we do not treat winter emergency HVAC service calls as less urgent because the temperature outside sounds mild to somebody from Denver.
What we will not do is turn an emergency into a sales opportunity. Our technicians are not paid commission on equipment, which matters most at exactly the moment when a homeowner is least able to push back on a recommendation. If the fix is a thirty-dollar part, that is what you get told at 9pm on a Sunday.
Not sure whether your situation is an emergency? The next section sorts that out honestly, including the cases where waiting until morning is the better call.
Is This Actually An Emergency HVAC Call?
Not everything needs a technician tonight, and we would rather tell you that than bill you for a call you did not need. Here is where we draw the line.
Call Now
- The indoor temperature is climbing past the mid-eighties in summer, or falling toward the fifties in winter
- Anyone in the home is elderly, an infant, pregnant, or has a heart, lung, or mobility condition
- There are pets in the home with no cool or warm space available to them
- The system is tripping its breaker repeatedly, or making a grinding or screeching noise
- There is water pooling around the indoor unit or dripping through the ceiling
- You have no heat and overnight temperatures are forecast to drop below freezing
Morning Is Fine
- The house is uncomfortable but holding, and the weather is mild for the season
- One room is wrong while the rest of the house is fine — that is usually ductwork or a zone damper
- The system is working but the bill jumped, which is worth diagnosing properly rather than urgently
- It is short cycling but still producing heat or cool air and the house is livable
- You noticed a new noise but the system is running normally otherwise
- It is a maintenance item you have been putting off and the season has not turned yet
If you are unsure which column you are in, call (702) 600-3737 and describe it. Deciding that over the phone costs you nothing.
What To Do Until We Arrive
Two very different situations, two very different sets of advice. Both matter more than people expect in this climate.
No Cooling, Summer
Close blinds and curtains on every window taking direct sun, and keep exterior doors shut. Move everyone to the lowest floor and the coolest room in the house — heat stratifies fast in a two-storey home.
Drink water steadily rather than waiting until you feel thirsty, use cool showers or damp cloths on wrists and neck, and run fans for air movement. Fans stop helping once indoor air passes roughly body temperature and can make things worse, so do not rely on them alone in extreme heat.
If the house is not holding and anyone is vulnerable, leave. A mall, library, or a relative's home is a reasonable answer, and Clark County opens cooling stations during heat events. Nobody should ride out a 115° afternoon to save a service call.
No Heat, Winter
Close off unused rooms and gather everyone into one space to concentrate the warmth. Layer clothing and blankets rather than relying on a single heavy cover, and let the sun into south-facing rooms during the day.
If you use a portable space heater, keep it three feet clear of bedding, curtains, and furniture, plug it directly into a wall outlet rather than an extension cord or power strip, and switch it off when you sleep or leave the room. Never use an oven, stovetop, grill, or generator to heat a home — that is a carbon monoxide risk, and it is how people die during cold snaps.
Keep the cupboard doors under sinks open if a hard freeze is forecast, so plumbing on exterior walls gets some warmth.
In both cases, check on elderly neighbours if you can. Heat and cold both do their worst damage to people who live alone and do not call anyone.
The Failures We See Most On Emergency Calls
Most emergency HVAC service calls in Las Vegas come down to a short list of components, and most of them are on the truck.
Summer — No Cool
Failed capacitors, burnt contactors, seized or stalled condenser fan motors, tripped safety switches, and refrigerant loss. Capacitors alone account for a large share of July calls, and they are a common part fitted once diagnosed.
Winter — No Heat
Dirty flame sensors shutting the burners down seconds after ignition, failed hot surface igniters, tripped limit and pressure switches, draft inducer failures, and control board faults. The first two are the most common no-heat calls we take by a wide margin.
Either Season
Blower motors, transformers, contactors, capacitors, and low-voltage wiring faults all serve heating and cooling alike. A component that strands you in January is the same one that would have stranded you in July.
Common wear parts are carried on the truck, so the majority of emergency repairs are completed on the first visit. Less common components — control boards, gas valves, compressors — may need ordering, and we will give you a realistic timeline rather than an optimistic one.
How An Emergency HVAC Service Call Works
You Describe The Situation
Tell us what the system is doing, what the indoor temperature is, and who is in the house. That last part genuinely affects prioritisation — a home with an infant or an elderly resident and no cooling in July is a different call from an empty rental.
We Book A Technician
We book a technician to come out and look at the system properly. Diagnosis happens on site, by someone who can actually see the equipment.
Diagnosis On Arrival
The technician reads any diagnostic codes, tests the ignition or cooling sequence, checks the electrical and control circuit, and measures airflow. The goal is the actual cause, not the first plausible part — even at eleven at night.
You Get The Price On Site, Before The Work
What failed, why, and what it costs to put right, in plain language and before anything is authorised. Nobody at this company earns more by recommending a system replacement during an emergency, which is the entire point.
Repaired And Verified
Before we leave, the technician checks the system over and verifies it is running to the manufacturer's specifications.
Is The One You Never Make
Many of the failures on this page involve components — flame sensors, igniters, capacitors, contactors — that an inspection puts eyes on before the season starts.
Two inspections a year, one before summer and one in autumn before the heating season, gives someone the chance to spot wear before the season finds it. It also keeps your manufacturer parts warranty valid, which catches a lot of people out at the worst possible moment. It does not guarantee a system will not fail between visits — nothing does.

Emergency HVAC Service FAQ
Yes. We take emergency no-cool calls through the summer and emergency no-heat calls through the winter, seven days a week across the Las Vegas Valley. Call (702) 600-3737 and describe what the system is doing — give us a call and we will get a technician out to check it over.
It can be. Valley winters sound mild from outside the state, but a house with no heat during a cold snap becomes genuinely unsafe for infants, elderly residents, and anyone with a health condition — and overnight temperatures below freezing also put plumbing at risk. We treat no-heat calls with the same urgency as no-cool calls rather than deprioritising them because the number outside looks manageable.
Leave the house. Do not switch anything on or off, and do not use light switches, phones, or the garage door opener inside. Once everyone is outside, call Southwest Gas or 911 — not us. Call us afterwards, once the property has been made safe, and we will handle the furnace side.
Get everyone outside into fresh air immediately and call 911. Carbon monoxide is colourless and odourless, and a cracked heat exchanger gives no warning without inspection. Take it equally seriously if people in the house have headaches, nausea, dizziness, or drowsiness that improve when they step outside, even with no alarm sounding.
Usually. Common wear parts — capacitors, contactors, flame sensors, igniters, fan motors — are carried on the truck, and those account for the large majority of emergency calls. Less common components such as control boards, gas valves, or compressors may need ordering, and we will give you a realistic timeline rather than an optimistic one.
Two things. First the thermostat — correct mode, setpoint several degrees past room temperature, and working batteries, which are a genuinely common cause of a completely dead system. Second the breaker: if it has tripped, reset it once. If it trips again, stop. That is the breaker doing its job, and repeatedly resetting it can turn a moderate repair into a large one.
It can be, with care. Keep it at least three feet clear of bedding, curtains, and furniture, plug it directly into a wall outlet rather than an extension cord or power strip, and switch it off before sleeping or leaving the room. Never use an oven, stovetop, grill, or generator to heat a home — that is a carbon monoxide risk and it is how people die during cold snaps.
Leave, if you can. Close blinds, move to the lowest and coolest room, drink water steadily, and use cool showers or damp cloths — but understand that fans stop helping once indoor air passes roughly body temperature. If the house is not holding and anyone is elderly, very young, pregnant, or unwell, go somewhere air conditioned. Clark County opens cooling stations during heat events. No service call is worth riding out a 115° afternoon.
No. Our technicians are not paid commission on equipment, which removes the incentive that makes emergency calls a sales opportunity elsewhere in this trade. If the fix is a small wear part, that is what you get told, even at nine on a Sunday night. If a replacement genuinely is the better answer, we will show you the numbers rather than assert it — see furnace installation and replacement.
