Your heat just went out. It's freezing. You're calling around trying to figure out what happened and how to fix it.
Stop. Take a breath. This is fixable, and help is available right now.
DME Maintenance has been serving Roslyn and Nassau County, NY since 2001. We understand exactly what happens when oil heat systems fail in the middle of winter—and we know the specific reason your system may have shut down safely to protect your home and family.
**What Happened to Your Heat**
When an oil heating system stops suddenly, it's usually because your furnace or boiler has triggered its safety switch. This happens for one reason: the system detected a problem and shut itself down to prevent damage or danger.
The most common cause in Roslyn, Roslyn Harbor, and Roslyn Estates is a blocked or restricted flue. Here's why this happens:
Roslyn sits on the North Shore with regular coastal breezes and historic masonry construction. Many homes here have chimneys built decades ago. Over time, creosote—a sticky, tar-like buildup—accumulates inside these chimneys. When creosote blocks the flue passage, your heating system can't safely vent combustion gases out of your home. The system detects this blockage and shuts down immediately.
It's actually your system working correctly. But that doesn't make your house any warmer.
Other possible causes include: - A clogged fuel filter or fuel line - An issue with the draft in your chimney - A problem with the combustion air intake - A malfunctioning nozzle or ignition component
Any of these can trigger that safety shutoff. The good news: most of these are found and fixed quickly by someone who knows what to look for.
**What Happens When You Call**
When you call DME Maintenance at 516-690-7471, here's what occurs:
You'll reach someone who can help immediately. We answer calls during heating season around the clock because we know emergencies don't wait for business hours.
Tell us your address and what you're experiencing. We'll ask a few quick questions: Is your system making any noise? Have you noticed any smells? How long has it been down?
We'll give you an honest assessment over the phone and tell you if we're the right fit for your situation. If you're in Roslyn, Roslyn Harbor, East Hills, or Roslyn Estates, we service your area regularly and we know your neighborhood.
We'll schedule an appointment that works for your emergency. If it's the middle of the night and dangerously cold, we come out. We don't charge differently for after-hours calls—your heat matters whenever it stops working.
DME Maintenance will arrive with tools and diagnostic equipment. They'll inspect your flue, check your furnace or boiler, test your fuel system, and identify what caused the shutdown. They'll explain what they found in plain English—not technical jargon—so you understand what went wrong.
Once the problem is identified, we'll discuss repair options with you. We fix what needs fixing and get your heat running again.
**Why Roslyn Homeowners Trust DME**
Douglas Eberling built this business on a simple principle: show up when people need you, do the work right, and be honest about what you find.
We've been doing this since 2001. We've worked on hundreds of homes throughout Roslyn, Roslyn Harbor, East Hills, and Roslyn Estates. We understand the specific heating challenges of older homes on the North Shore. We know how creosote buildup happens in historic masonry chimneys. We've seen every variation of oil heat system failure.
When a homeowner calls us in a panic because they have no heat, we don't panic. We solve the problem.
**What You Should Do Right Now**
Call 516-690-7471 immediately.
Have your address ready. Describe what's happening with your system. If you know when it stopped, tell us. If you smell anything unusual, mention it.
Don't attempt to restart your furnace repeatedly. If it shut down, it did so for a reason. Repeatedly trying to restart it can cause damage.
Keep your home as warm as possible. Close off rooms you're not using. Open cabinet doors under sinks to let warm air reach pipes. If you have space heaters, use them carefully.
Then wait for our call back or our technician's arrival. We'll take it from there.

**Frequently Asked Questions**
**Q: Is my system broken beyond repair?** Most no-heat emergencies in Roslyn are fixable quickly. Flue blockages, fuel filters, and combustion air problems are routine repairs. We won't know until we inspect it, but most calls we respond to result in the system running again the same day.
**Q: Why did my heat stop without warning?** Your safety switch is designed to shut everything down the moment it detects a problem. This includes flue blockages, fuel line issues, or combustion problems. It's protecting you. The system didn't fail—it did its job.
**Q: What should I do while I'm waiting for me?** Keep your home as closed up as possible to hold heat. Use blankets and space heaters if you have them. Don't keep restarting your furnace. Have your thermostat set where you want it and leave it there.
