What Causes the Burning Smell?

Heating and cooling repair is a frequent process in households. You need to know the major causes that might create a burning smell from your heater. 

1: Congested Air Filter 

A jammed air filter fosters tons of dust, hairs, and scraps. The pungent air while passing through it, can create an irksome burning odor. The air filter will eventually limit the smooth airflow into the engine, resulting in an insufficient air supply. You can overcome this complication by replacing the filter with a new one! 

2: Dirt 

You can get a burning smell while switching on the heater for the first time, or after a prolonged gap. It is very obvious for the dust to accumulate on heaters or burners during the warm seasons. When the heater launches, the dust starts to go up in smoke, causing an unpleasant odor. However, the scenario settles down in a few minutes and doesn’t represent any serious problem. 

3: Cording Complications 

Sometimes, the smell results due to wiring complications too. Issues with the electrical system of the model aren't very common, however might occur at times. In such a case, you need to dive deep into the root of the problem and figure out what the matter is, as it can indicate something serious. If you replace the filter newly, and the smell continues to get deep, the time is for calling a air conditioning professional. 

How to Fix it?

A heater is a common need in most houses. Therefore it is significant to know the vital fixtures to get rid of the unpleasant pungent odor. What can you do to prevent such a scenario?

• Frequent maintenance of the heating and cooling model is a great step to stay away from all these odor complications. Inspection at least once a month can prevent the dust particles from accumulating on the heater and develop a burning smell.
