HVAC Service Eagan MN

Your HVAC system exists in order to provide a comfortable environment in your home or business. The primary method of maintaining comfort is in heating and cooling circulated air. Your system only works as good as it’s serviced, so you’ll need to have a qualified, professional HVAC service technician regularly maintain it.

How HVAC Systems Work

The air’s moisture content is expressed as a percentage of relative humidity: how much moisture the air holds in relation to how much it could hold at its current temperature. Air with a relative humidity of 50 percent has half as much moisture in it as it could hold. Warmer air is able to hold more moisture than colder air. High relative humidity makes us feel warmer, while low humidity produces a cooling effect.

During the summer, the air is warmer and contains a lot of moisture (humidity). Your system operates in the cooling mode 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 lower humidity.

Effects of Low Humidity

The air is usually quite dry in the winter. The temperature will need to be warmer in order for you to feel comfortable with low relative humidity. Low humidity air also tends to dry out wooden furniture, resulting in cracks and loose joints and can contribute to respiratory problems.

Dry air also results in 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 can explain the advantages and options of the types available for you.
