Humidity pertains to the amount of moisture in the air. This naturally varies day by day according to the weather. On average, we experience high humidity during the summer and low humidity during the winter. Mild conditions can be taken in stride but extremes on either end of the spectrum can affect comfort levels despite the presence of HVAC systems. We discuss how humidity impacts air conditioning and heating below.
The Effect of Humidity on Air Conditioning
Air conditioners are called upon to provide cooling when the temperatures outside are getting hot. They are also there to control the humidity inside the room. The dual roles of cooler and dehumidifier are important. No matter how low the temperature setting might be, it will still feel uncomfortable if the humidity cannot be contained. This needs to be addressed as well to create the perfect living environment.
A/C units reduce the moisture in the air through condensation using the cold coils at the front of the unit. While the compressor is working to low the temperature of the room, this condensation will continue. The size of the unit should fit the demands of the room because an overly powerful air conditioner will reach the desired temperature too quickly and shut off before removing enough of the humidity inside. Using a dehumidifier can help solve the problem.
The Effect of Humidity on Heating
The opposite happens during the winter as humidity gets too low for comfort. If high humidity makes a room feel hotter than it is, then low humidity makes a room seem colder. People may be tempted to increase the temperature setting on the heater but this can only be raised so much before it starts getting unreasonable. The problem must be dealt with specifically, usually through the use of a humidifier. This may be installed on the heater for best results. This adds moisture to the air before it circulates through the ducts. It is a good thing to have when humidity falls below 50%.
