furnace smellsThere are a variety of reasons your furnace smells, including the following:


– This is a very common and minor issue. It is very normal to have somewhat of a dusty smell when you turn on your furnace for the first time each and every year since dust will collect on the furnace air filter when it is not in use. This furnace smell will definitely burn off quickly. No need to fret.


– This is yet another minor and common issue. If there is any type of mold at all on the air filter it will definitely cause a musty smell when you turn the furnace on. This problem will not resolve itself, however. It is necessary for you to either wash your filter and dry it completely or change and install a new air filter.


– If you notice a smoke smell this typically is a sign of a major issue that should be addressed immediately. If you have a chimney that is blocked it will cause smoke to flow through the duct work. We would suggest that you have your chimney inspected and cleaned right away by a chimney professional.


– If there is an electrical smell present when you turn the furnace on this is an indication of a major problem. More than likely you have a burned out motor, frayed wiring, or other electrical parts that are malfunctioning. Contact the expert emergency technicians here at Hometown Comfort to perform an inspection of your furnace immediately.


– An oil smell can be either a minor or a major issue. If a filter is clogged it can cause an oil smell which is a rather simple and minor issue. In order to resolve this issue, simply change the filter which will alleviate the furnace smell. If, however, you continue to notice the smell of oil, then again give a call out to our professional HVAC technicians so we can check for an oil leak which can ultimately turn into a serious and costly problem.


– If you detect the smell of sulfur when you turn your furnace on, this is surely a more serious problem. This sulfur smell is caused when there is a leak in your furnace or in your main line and may very well result in an explosion if it is not attended to immediately.


Whether you have a simple or a complex problem with your furnace or a minor or major furnace smell, it is important you obtain the professional services of our technicians as soon as possible. The simpler issues described above have easy to accomplish quick fixes. However, the more complex issues can ultimately lead to more serious and costly problems and should be addressed immediately in order to maintain the health and safety of your family.
