Why Your Air Conditioning Units Give Out Musty Odours?



Inhaling musty odors the moment you turn on your AC conditioning units?  The cool air should be fresh and free of smells.  Breathing in unhealthy air can lead to respiratory problems. This is where you need the help of an air conditioning service & repairs in St Mary's.  This blog lists out the reasons as to why your air conditioning unit emits odors and how to get rid of them. 

  • Frozen evaporator coils:
It is important for free-flowing air to circulate well when the air conditioning unit is switched on.  It eliminates humidity by absorbing hot air from the surroundings, cooling, and emitting cool air.  In order to get clean fresh air from these units,  the air filters need to be clean.  With prolonged use, dust and dirt tend to accumulate in the filters and other components blocking the free flow of air. Water droplets accumulate and get frozen on the evaporator coil when the AC is running. Hire a skilled technician for Air Conditioning repairs and to clean and replace the filters regularly.

  • Excess moisture:
With high humidity levels and hot air circulating in the surrounding, excess moisture collects in the vents of the units.  This can affect the quality of air and give out a musty smell. You will find that mildew and mold have accumulated and taken up space inside the air vents. 

Regularly breathing in this musty air generated from the air conditioning units can lead to chronic respiratory complications.  Get a technician to do a thorough cleaning of blocked air vents and ducts. 

  • Overflowing drain pan:
 When an air conditioning unit Is running it absorbs the warm and humid air, and the excess cooled moisture forms as water droplets that drain out into the pan.  This is the area that sees regular activity resulting in wear and tear and it tends to get damaged with use over time. A Drip pan that is designed ineffectively can collect mold and debris giving out putrid smells.  Air conditioning services should include the performance of regular cleaning and maintenance of the drain pan. You can also get a professional air conditioning technician to replace it.

  • Clogged up condensate line:
The condensate line can be seen connected to the unit outdoors.  Its main function is the drain out the excess water from the drip pan to an outlet at your home.  Due to the continuous flow of water there is a lot of build-up of mold, mildew, fungi, and bacteria.  The narrow line tends to get blocked giving out musty odors. Hire an air conditioning servicing technician to clean it once a month. The condensate line needs to be detached from the air conditioning unit to clear out all the impurities. It is then reattached to perform its function to perfection.

  • Incorrect air conditioning unit size:
An ac conditioning unit should be fitted depending upon the size of the room in which it is to be installed.  It should be capable of a specific capacity. Incorrect air conditioning unit size can cause it to fluctuate on and off without any cooling effect.
