Your HVAC system is there so you have a comfortable environment in your home or business. Most HVAC systems work by heating and cooling circulated air. Your system needs to be serviced to maintain proper function, so a qualified, professional HVAC services technician in St Paul or a nearby area will need to regularly maintain it.
How HVAC Systems Work
The moisture content in the air is stated as a percentage of relative humidity, i.e. how much moisture the air holds in relation to how much it could hold at its current temperature. For example, air with a relative humidity of 50 percent has half as much moisture in it as it could hold. Warmer air can hold more moisture than colder air. Higher relative humidities make us feel warmer, while low humidities produce a cooling effect.
The summer air is warmer and contains a lot of moisture (humidity). Your air conditioner helps to lower the temperature. Since cold air cannot hold as much moisture as warm air, the process lowers the air temperature by condensing out of the air a lot of the moisture, thus resulting in a lower humidity.
Effects of Low Humidity
The air is usually quite dry in the winter. A warmer temperature is necessary for comfort in low relative humidity. Low humidity air also tends to dry out wooden furniture and can contribute to respiratory problems.
Dry air also causes annoying static electricity when you walk on carpets with certain kinds of shoes, or when different types of fabrics rub together. To increase relative humidity in winter, your heating and cooling system should have a humidifier.
There are several types of humidifiers available that can be easily installed in existing HVAC systems. A qualified heating and cooling contractor like Aabbott Ferraro, serving St Paul, can explain the advantages and options of the types available for you.
