Hot and humid conditions allow the mold to grow. But mildew is very toxic and hazardous for humans. When humans are exposed to mold, it can trigger asthma symptoms and other illnesses such as headache, nausea, sore throat, etc. If you have respiratory diseases, you should be more worried about the growth of mold in your house.

As Dallas is very humid, if you don’t maintain a specific humidity level and put off the air duct cleaning, you can notice mold formation in your AC system. Besides, when there is condensation in your air conditioning unit, you might notice mildew in your HVAC unit, especially in the AC vent.

After identifying the mold growth in the AC vents, you will have to call a professional air duct cleaning expert and clean the air ducts. If there is excessive mildew in the air ducts, you may have to call professional pest control.

Several HVAC companies provide air duct cleaning near Dallas and Fort Worth. Before hiring them, ensure that the HVAC company is certified and has enough experience to clean the air ducts.

A dehumidifier keeps the moisture content at the same level and thus helps you maintain a comfortable indoor environment. You just need to set a humidity level, and the dehumidifier will control the humidity accordingly. Usually, a humidity level of 55%-65% is considered ideal. Above or below this level will cause several issues. For example, excess humidity can make you feel sweaty, trigger mold growth, and make the HVAC unit operate longer. On the flip side, when the humidity is low, you will have skin irritation and dryness.
