There are few things worse than turning on your heating system on a cold day and being greeted with an offensive smell. You want to keep your home at a comfortable temperature, but doing so means dealing with a potentially awful smell. Does your furnace need to be repaired? Read on to find out. Let’s look at the possible causes of strange smells.
Your furnace may need repairs, but not necessarily. What exactly is the smell like? If it smells like something is burning, wait and see how long the smell lasts. Dust can settle in the heating system if it has been a while since you have turned on your heat. When you first turn on your heater after a long period of disuse, you may experience a burning smell as the system burns off the dust. This is nothing to worry about, and the smell should subside shortly after you first start the heater. If the burning smell persists, you may have a more serious problem.
Dirty Air Filter
A dirty air filter is also a possibility. If you experience a musty smell when you turn on your heater, check your air filter. If it is dirty, clean or replace it and see if the smell goes away. If you don’t know how to check your air filter, an HVAC professional can do it for you.
If moisture somehow finds its way into your heating system, usually through leaks in the ducts, it can cause mold to grow. Some types of mold can give off a very unpleasant smell, which will be distributed throughout the house when the heater is turned on. Usually, a duct cleaning and sealing is enough to fix this problem.
If the smell coming from the vents is that of decay, you may unfortunately have a dead animal in your vents. This can happen sometimes when a squirrel or raccoon finds its way into your duct system and can’t find a way out. This is often the most offensive smell to come out of your heating vents. An HVAC technician can safely remove the animal for you, which should get rid of the smell.
