Relative indoor humidity levels are more than just a comfort factor; it can impact your HVAC system’s performance and efficiency. In today’s post, local air conditioner service contractor Mechanical Technologies explores these effects, and discusses how you can counter them.

High Vs. Low Humidity Levels

An air conditioner’s cooling process involves drawing the moisture from the air. Not doing so would result in cold and clammy indoor spaces. During humid seasons, air conditioners need to work harder to draw the moisture from the air. The corresponding increase in workload results in more energy consumption, as well as increased strain on the system. Areas where moisture remains trapped are more likely to foster mold growth, which can affect indoor air quality levels.

Comparatively, low relative indoor humidity levels — typical during cold seasons — can have a different effect. In addition to its health effects such as dry skin and throat discomfort, it can also trigger various respiratory issues. Dry air can also make the air feel cooler than it is. This causes some people to turn up the heat more frequently, which can result in an increased workload that uses up more gas, fuel or electricity, depending on the heating system. It may also lead to more frequent heating and AC repair appointments.

How to Maintain Balanced Indoor Humidity Levels

You’ll have noticed that both extremes have the same effect on heating and cooling systems: increased workload that leads to greater strain and higher utility bills. It may even shorten your HVAC system’s life span. The ideal indoor humidity level is between 30% and 50%, where HVAC systems can operate efficiently and with lower strain.

To control humidity levels, you can have a humidifier/dehumidifier integrated into your HVAC system’s air handler. Some units are compatible with smart systems that let you monitor relative indoor humidity levels accurately. Best practices, such as turning the exhaust fan when you bathe and the range hood when you cook, can also help reduce moisture in the air. If you’d prefer to use standalone humidity control units, choose those with a built-in hygrometer to keep an eye on humidity levels. Standalone hygrometers can also be purchased separately.
