Answer: The primary function of an HVAC unit is to regulate the temperature of the air inside the home and control the airflow as well. However, sometimes you might experience a foul smell from your HVAC unit. When the odor becomes strong and persistent you need to become careful and get in touch with a trusted HVAC professional. Some of the causes of foul smell from an HVAC unit are the following: Many a times you might experience a dusty or moldy smell from an HVAC unit. The reason is quite obvious. When the HVAC unit is not used for quite some time dust sits on the unit and as you switch on the HVAC unit after sometime the dust burns up and you might experience a foul smell from your HVAC unit. Smell of rotten eggs from an HVAC unit may be due to leakage of gas from an HVAC unit. On the other hand when you are experiencing a burning or smoldering smell from the HVAC unit it is certain that it is due to some fault in the condensation unit. Last but not the least; dirty filters could be another factor causing foul smell from HVAC units. Hence, it is important that you get in touch with a trusted HVAC professional so that you can eliminate foul smells from your HVAC unit and also preventing the causing of severe damage to your HVAC unit in the long run.
