24 Hour Emergency HVAC Service, Silver Spring MD

No heat during a freeze is an emergency, and it is the most common winter call we take. When outdoor temperatures sit in the twenties or lower, an unheated house loses ground quickly, and the risk moves past discomfort to frozen pipes inside exterior walls. No cooling during a heat wave is the summer equivalent, and it becomes urgent faster than people expect when the house holds elderly residents, infants, anyone with a heart or respiratory condition, or anyone recovering from surgery. An upper floor bedroom during a Mid-Atlantic July can climb well past what is safe.

Water pouring or steadily dripping from a unit is an emergency because of what it damages while you wait. A clogged condensate line on a downtown Silver Spring or Bethesda condo fan coil shows up as a stain on the ceiling of the unit below. An attic air handler in a rambler can soak drywall and insulation across a whole hallway before morning. Shut the system off at the thermostat and call. A burning smell is also a call now rather than later, particularly an electrical or hot plastic smell as opposed to the ordinary dust burn off on the first heating day of the season.

A system that trips its breaker repeatedly is an emergency in the sense that it should not be reset again. One reset is reasonable. A second trip means something downstream is drawing more current than the circuit allows, and that is usually a failing compressor, a seized motor or damaged wiring. Leave the breaker off and call. The same goes for loud grinding, screeching or banging from the equipment, or a unit that is visibly smoking: shut it down at the breaker and leave it off until someone has looked at it.

Plenty of things feel urgent at 10 PM and are genuinely fine until business hours. A house a few degrees off setpoint in mild weather. A thermostat with a blank screen, which is very often just batteries. One room that runs warmer or cooler than the rest, which is a distribution problem that has probably existed for years. An outdoor unit that is noisier than usual but still cooling. A filter you have not changed since spring. None of those get better with an overnight visit, and waiting until morning costs you nothing.

Weighing it comes down to three questions: is anyone in the house at risk, is water or fire damage happening right now, and is the equipment doing something that gets worse if it keeps running. If the answer to all three is no, morning is fine. If you are not sure, call anyway and describe what is happening. We would rather talk it through on the phone and tell you it can wait than have you sit on a real problem overnight because you did not want to bother anyone.

If you smell gas, do not call us first. Leave the house. Take everyone with you including pets, do not touch a light switch, do not unplug anything, and do not use the garage door opener, because any of those can create a spark. Once you are outside and away from the building, call 911 and then the gas company. Washington Gas maintains an emergency line for this. Do not go back inside for any reason until someone with instruments tells you it is safe. We can come out after the gas side has been cleared.

Carbon monoxide follows the same procedure, and it is more dangerous because there is nothing to smell. If a CO alarm sounds, or if several people in the house have headaches, nausea or drowsiness that improves outdoors, get everyone out and call 911 from outside. Do not go back in to look for the source, and do not stop to open windows on the way. Ventilating before responders arrive can make the source harder to find. Once the house is cleared, the equipment problem underneath it is ours, and it has to be found before that system runs again.

For a no heat call in winter, keep the house together. Close off unused rooms, gather everyone into one or two spaces, open the cabinet doors under sinks on exterior walls, and if it is severely cold, run a thin trickle of cold water at the fixture farthest from where water enters the house. Do not heat the house with a gas range, a charcoal grill or an unvented outdoor heater, and never run a generator in an attached garage or near a window. Those are the two ways a cold night turns into a carbon monoxide call.

For a no cooling call in a heat wave, close the blinds on the sun side, run ceiling and box fans, drink water, and move anyone vulnerable to the lowest level of the house, which is always the coolest. For a water leak, shut the system off at the thermostat and put down towels or a bucket. For anything electrical or burning, shut it off at the breaker and leave it off. Write down what you noticed and when, because what the system did right before it stopped is often the most useful thing you can tell us.

Call the number, tell us what is happening, and we will tell you on the phone what to expect. That includes whether this is something to handle tonight or something genuinely better handled in the morning, what the visit involves, and the cost structure before anyone is dispatched. We do not post arrival times or pricing on a web page, because those depend on the night, the call and the job, and a number printed here would be a number we might not be able to honor. You get real answers on the phone instead.

On the visit itself, expect diagnosis before repair. A technician finds out what actually failed and why, then tells you what it takes to fix it and what it costs before starting. Sometimes the honest answer at 1 AM is a safe temporary fix now and the correct repair on a normal day, when the part is available and the work can be done properly. We will say so when that is the case.
