Smoke Puff Back Furnace Poughkeepsie

What can you do when furnace puff back affects your property?

To give your home the best chance of a full recovery without causing further harm to paintwork or carpets, you should enlist professional fire damage restoration services from the Poughkeepsie area.

What is a smoke puff back made from?

Smoke puff back from a furnace in your Poughkeepsie property is a composite of different soils that can stain furniture, embed into carpets, cause odors or damage your paintwork. You can expect to find a mixture of wet and dry soots in a furnace puff back. Some soots may be several months old, which can vary the texture, greasiness, and cleaning methods we need to use. It is prudent to pre-test each soot to understand how they react to cleaning methods as well as how the base material reacts.

Do not apply water or household cleaning products until necessary or with expert advice. Some puff backs can contain fuel oil, which is insoluble in water. Applying a water-based cleaning product to oil-based soiling can split, which usually results in spreading fire damages further around. SERVPRO technicians stock a full range of water and oil-based chemical agents to help remove soots from surfaces with minimum harm.

What is furnace puff back?

A puff back occurs when there is un-burned oil at the bottom of a boiler or heater's combustion chamber. When the ignition is applied, the un-burned oil quickly explodes, sending fuel oil, ash, soots, and other debris through the venting system. While the force of the explosion is not usually enough to cause structural damage to your home, it can dislodge soot buildup inside venting and create enough pressure for soots or debris to be blasted out of return ducks throughout the home. A common sign of a furnace puff back is soot lines directly above and in front of ducts.

Why does puff back occur, and how to avoid it?

The most common cause of a puff back is poor maintenance of a boiler or fuel burner. Over the years of use, boilers perform less efficiently. These can be the result of blocked ignition or spray nozzles that leave oil un-burned in the combustion chamber. Issues can also be the result of:


- Improper shut-down of the boiler
- Leaky or loose-fitting fuel supply lines
- Inadequate chimney fittings (too short) or weak installation of a furnace in the home
- Heavy usage over long periods
- Leaving flues closed during operation

What signs are there that a puff back could occur?

Usually, there are warning signals that a homeowner can be aware of to prevent a puff back from occurring. The most common signs are odorous, dirty, or noisy operation of the furnace. Unusual sounds, smells, or emissions can all be symptoms of an inefficient furnace. These can often be treated cheaply by getting professional inspection and repair. Further signs may include:


- Soots or other types of marking around the furnace
- Slow ignition
- Slow shut-down
- Rumbling noises in your boiler
- Oily smells from both venting ducts and furnace itself.

What can I do to remedy a puff back?

Smoke puff backs are composed of wet and dry smoke residues as well as fuel oil. These can make cleaning efforts challenging without industry training and experience. However, relatively safe measures you can take are to shut-down your boiler. Light-vacuuming, the affected area, can be an effective way of tackling dry soots. You may also want to avoid foot traffic in the affected area to prevent any residual soots from pushing into carpet fibers or other areas.

Is puff back smoke damage on my carpets permanent?

SERVPRO technicians can help you to understand which items are salvageable and which are not salvageable. Our workers conduct a simple equation regarding the cost of replacement, cost of restoration, and cost of materials before deciding to discard carpets. Often our exceptional pre-cleaning, pre-conditioning, and rotary machines can help to reduce heavy soils from a carpet and restore it to a preloss condition.

Massive set soiling in thick carpets can also benefit from emulsifying cleaning technology. Emulsifying powders can be applied directly onto most carpets and loosens the bond of soots and carpet fibers. Often the emulsifying powder dislodges soots successfully with both soot and powder being extracted from the carpet at the end of service. If your carpet features thin carpet fibers, you may benefit from a replacement that SERVPRO can perform for you on-site.

Furnace puff backs are not easily avoidable, but they can impact your home visually, physically, and affect your indoor air quality. Using professional assistance can help to ensure that your property returns to its preloss condition without the risk of further harm occurring.

If you suspect a furnace puff-back in your home, contact SERVPRO of NW & SE Dutchess County at (845) 635-4550.
