Nothing goes without a trace – even fuel in your furnace. In the process of fuel burning, soot, cinder, and ash accumulate on the walls of the firebox and chimney. No matter how high quality your fuel has, sooner or later, you will require a qualified furnace cleaning service. The Best Heating Cooling & Air Company provides this service among its list of repairs and maintenance services for furnaces. When our technicians get to work, any furnace shines with pleasure and cleanliness, bringing much joy to its owners, year after year.

Why do you need to clean the furnace?

Soot, cinder, and ash are deposited with time on the walls of the firebox, ventilation ducts, and chimney. If you don’t do regular cleaning of the furnace, those deposits accumulate above the norm and decrease the pipe section, worsening the smoke extraction as a result of worsened furnace draft and you get the lowered efficiency of a furnace:

• The system heats up too slowly, it might be hard to start a fire


• Fuel consumption increases, so as your electricity bills


• Cold spots start to form on the premises


• Prolonged contact with products of burning increases the corrosion rate and lowers the life term of the furnace.

If you have high clogging of a chimney, a backdraft appears: instead of leaving the premises that are being heated, the smoke is pulled back, the soot and ash get deposited on the walls of rooms. As a result, the premises look less tidy, an unpleasant smell appears. Besides, inhaling fumes for a long time is dangerous for health. By not cleaning up your furnace on time, you risk joining the number of people with allergies and those having asthma while you also make headaches and colds your constant partners. Sometimes, dirt and soot deposits can spontaneously inflame from sparkles, and that flame coming from a furnace can cause arson.  

Is chemical cleaning enough?

You might have seen many chemical remedies designed for cleaning up the furnaces. However, you cannot entirely rely on those solely: while a substance actually could dissolve some part of the soot and dirt, it would definitely not be enough for keeping the furnace in a fully working and nice technical condition. The best effect is obtained from a combination of mechanical and chemical approaches to cleaning. The right technique of cleaning also matters.

How frequently does furnace cleaning have to be made?

If you exploit your furnace in a standard manner, it is advisable to clean it twice a year – at the beginning of the heating season and after its completion. Do it as a part of pre-scheduled yearly maintenance. In such a case, you will have enough time to find any possible troubles with a furnace and eliminate them in a proper manner – otherwise, a large breakage might occur out of the blue, leaving you cold in the midst of winter.

If you have a solid-fuel furnace installed and the quality of that fuel is not always high, it is advisable to clean your furnace thrice a year; brick chimneys should be inspected once per 3 months. Additionally, the need to clean can be more often if there are unevennesses on the walls of the chimney and air ducts, as they can catch more soot deposits. If your chimney top does not have a cap, foreign objects might get inside. 

How do you understand you need unscheduled cleaning of a furnace?

Some nodes of a furnace can get dirty as a result of finishing or renovation made inside the premises. That’s why it is recommended to clean it after these works are finished. Also, you would need to clean a furnace after you get to a new house or you could agree with a seller about furnace cleaning before you get in. Additionally, clogs might happen even if you comply with the exploitation requirements at 100%. So, if you spot any of the signs of furnace clogging, you should do the cleaning:

• Uneven warming up of the premises. If a furnace is relatively young and has never had complaints about its wellbeing before but you still feel spots of cold in your house, probably, the reason is furnace clogging. Too much cinder and soot in it serve as thermal insulation due to their porous structure and lower the airflow speed, leading to decreased heat exchange of the furnace.


• Condensate starts to appear. Because of the lower draft, air moves on the smoke channel too slowly and has enough time to cool down while steam is condensed on the chimney walls. Furnaces working in a smoldering mode are especially prone to leakages: because of low temperature in the chimney, even the slightest losses of energy become critical.


• Flame color changes, sparks, or black smoke appear. If the chimney and firebox are clogged too heavily, the soot and cinder can get into the fire, bringing unusual and dark colors to it.
