Emergency HVAC Service in Germantown, Gaithersburg and Rockville
When the heat dies on a cold night or the air conditioning quits in the middle of a heat wave, you need to know whether someone is coming, when, and what to do in the meantime. Mora Heating & Air takes no-heat and no-cooling calls in Germantown, Gaithersburg, Rockville, Montgomery Village, Potomac, Olney and Boyds, and treats them as what they are: urgent. They move to the front of our schedule, ahead of routine work, and you get a real arrival window you can plan around.
Here is what we will not do: promise a response time we cannot keep. Any company can say a technician is minutes away; keeping that promise on the coldest night of the year is another matter. We tell you honestly when we can be there, and if the earliest opening does not work for your situation, we say so and help you bridge the gap safely.
What Counts as an HVAC Emergency?
Not every breakdown is urgent, and pretending otherwise helps nobody. These are the situations we prioritize, because waiting makes them worse or dangerous.
No heat in winter
A home losing heat in cold weather is a safety issue and a property issue. Pipes can burst, and vulnerable household members are at real risk. No-heat calls go to the front of the schedule.
No cooling in extreme heat
During a heat wave, a failed air conditioner is dangerous for infants, older adults, and anyone with a medical condition. We treat these calls with the same urgency as winter no-heat calls.
Suspected gas leak
This one is not our first call, it is your utility's. Leave the house, then call your gas utility or 911 from outside. Once the utility has made the home safe, we handle the equipment repair.
Water or ice where it should not be
A leaking indoor unit, an overflowing condensate pan, or an outdoor unit encased in ice signals a fault that damages more the longer it runs. Shut the system off and call us.
How Priority Scheduling Works
Urgent calls are triaged, not queued. When you call with no heat or no cooling, we take the details, confirm it is a priority situation, and place you ahead of routine maintenance and non-urgent work. You get the earliest genuine opening we have and an arrival window based on the actual schedule, not on what sounds good over the phone.
Germantown and Clarksburg were built in waves, so identical builder equipment put in the same season tends to quit the same week. On the first real heat wave that is not bad luck, it is the calendar. During severe weather, demand spikes and every contractor's schedule fills. If our earliest opening is not soon enough for your household's situation, we will tell you that plainly instead of stringing you along, and we will walk you through keeping the home safe until the visit.
What to Check Before You Call
A meaningful share of urgent calls end at a tripped breaker or a dead thermostat battery. Two minutes of checking can restore your system before we ever dispatch, and if it does not, what you find helps us diagnose.
Thermostat
Confirm it has power, the batteries are not dead, and it is set to heat or cool with a temperature that should trigger the system. A blank or unresponsive screen usually means batteries or a tripped circuit.
Breakers and switches
Check the breaker panel for a tripped breaker serving the furnace, air handler, or outdoor unit. Also check the light-style service switch near the furnace, which gets flipped by mistake more often than anyone admits.
Filter
A severely clogged filter can overheat a furnace or ice a coil until the system shuts itself down. If the filter looks like felt, replace it, then give the system time to reset before judging the result.
Outdoor unit and condensate switch
Look for an outdoor unit buried in snow, debris, or ice, and check whether a condensate float switch has shut the system down over a full drain pan. Clearing the pan or the drain sometimes restores operation.
How Do You Stay Safe While You Wait?
In a no-heat house, close off unused rooms and gather the household into one or two spaces. Use space heaters only on the floor, away from bedding and curtains, plugged directly into wall outlets, never into power strips. Do not use the oven or any outdoor cooking equipment for heat, and make sure carbon monoxide detectors are working. If temperatures will stay low for hours, open cabinet doors under sinks on exterior walls and let faucets drip to protect the pipes.
In a no-cooling house during extreme heat, move to the lowest level, close blinds against the sun, run fans, and drink water steadily. Check on elderly neighbors and family. If anyone in the home shows signs of heat illness, confusion, dizziness, or skin that has stopped sweating, that is a medical emergency before it is a mechanical one. Call 911 first.
What Happens When the Technician Arrives
The visit starts with your account of what happened, then a diagnostic pass through the system to isolate the actual fault. Not every dead system is a dead system. Most Potomac houses run two systems with zone dampers added later, and a failed damper motor gets read as a failed unit more often than you would think, so we rule out the simple causes first. You get a plain-language explanation and written options before any repair work begins, even on an urgent call. Urgency changes the schedule; it does not change the standard.
Most urgent calls end with the system running again that visit. When the failure is terminal, a compressor gone on an aged system, a cracked heat exchanger, we will say so directly, get you safe and stable, and give you replacement options without using a cold house as leverage. Pressure selling during an outage is something we want no part of. Out toward Boyds, where a second trip costs a day rather than an hour, we bring the parts the symptoms point to on the first visit.
What we check besides the broken part
A part that failed had a reason for failing. Low airflow. A dirty coil. A wire running hot. A drain backing up. If that reason is still there when we leave, the new part is on the same clock as the old one.
So the visit covers the rest of the system, not only the piece that quit. If we find something that was working against it, we tell you what it is and what it would take to put right.
Frequently asked questions
What should I do if my furnace stops working at night?
Check the basics first: thermostat batteries and settings, the breaker panel, the service switch near the furnace, and the filter. If the system stays down, call us. No-heat calls receive priority scheduling and an honest arrival window. While you wait, consolidate the household into fewer rooms and use space heaters safely, plugged directly into wall outlets.
Is a broken air conditioner really an emergency?
During extreme heat, yes. High indoor temperatures are genuinely dangerous for infants, older adults, and people with medical conditions, and Maryland heat waves arrive with humidity that makes homes worse than the thermometer suggests. We treat no-cooling calls during heat events with the same priority as winter no-heat calls. In mild weather, a cooling failure is urgent but rarely dangerous.
Do you promise a specific response time?
No, and we are deliberate about that. A promised response time that collapses during the first cold snap is worse than no promise at all. What we commit to instead: no-heat and no-cooling calls move ahead of all routine work, and you get an arrival window drawn from our actual schedule, one you can plan around.
What should I do if I smell gas?
Leave the house immediately. Do not operate light switches, phones, or anything that can spark while inside, and do not try to locate the leak. Call your gas utility or 911 once you are outside. The utility responds to gas odor calls around the clock and makes the scene safe. After that, call us to repair whatever the equipment needs.
Why is my outdoor unit covered in ice?
Shut the system off, because running it encased in ice can destroy the compressor. In summer, icing usually points to low refrigerant or restricted airflow from a clogged filter or dirty coil. In winter, a heat pump wearing light frost is normal, but a solid ice shell means the defrost cycle has failed. Either way, it needs diagnosis, not patience.
It is late and the heat is out. What should I do first?
Check that the thermostat is calling for heat and that the furnace switch and breaker are on, because those two account for a fair share of no-heat calls. If both are fine, keep the house closed up, run a space heater only where you can watch it, and call us. Tell us what the system was doing before it quit. That usually tells us what to bring.
Which towns do you take urgent calls from?
Clarksburg, Germantown, Boyds, Montgomery Village, Washington Grove, Gaithersburg, Darnestown, North Potomac, Travilah, Derwood, Redland, Rockville, Potomac and Olney. That is the whole map, and it is deliberately small. Distance is the part of an urgent call that nobody can speed up.
No heat or no cooling right now? Call us. We will tell you honestly when we can be there and what to do in the meantime.
