Leave Puffback Damage to the Professionals

A furnace puffback is often the result of fuel accumulation within the system

Businesses in Stillwater, OK, with an oil furnace know the importance of regular maintenance and annual inspections to keep systems operating properly. If the system gets clogged, it can result in puffback damage, which is a backfire that sends smoke and soot into the building. Not only does that affect the air quality in the building, but it also results in a mess that is difficult to clean.

What Causes a Puffback?

A furnace puffback is often the result of fuel accumulation within the system. The causes of this issue include:

Leaks – Fuel enters the furnace through a supply pipe. When in operation, high pressure and heat create air bubbles. Once the system turns off, those bubbles can expand and push unburned oil into the combustion chamber.

Shutdown Issues – Furnaces have a valve that keeps the fuel from flowing after it shuts down. If that valve is damaged, it may not properly close.
Spray Nozzle Problems – When working properly, the nozzle will properly feed fuel into the system. A clog, crack or other damage can impact the even distribution of fuel.

Improper Venting – These systems are designed to ensure gases are released to ensure a proper balance. Poor ventilation can trap the gases in the furnace, creating combustible accumulation.

Steps to Take After Puffback

After experiencing puffback damage, the first steps are to turn off the system, document the incident for insurance and contact an HVAC professional for an inspection. Once the problem is repaired and it's safe to turn back on, you are left dealing with a mess. While it may be tempting to clean it yourself, that soot contains oil and easily smears. It can also leave a long-lasting odor.
Contacting a professional restoration company can ensure the damage is properly cleaned. Along with having the tools and expertise to eradicate the visible sticky residue and lingering odor, they will inspect the entire property for hidden damage to ensure everything is back to normal.
The best bet is to avoid puffback damage by properly maintaining your heating system. Any signs of leaks or improper function should be a fast warning sign to get an inspection.
