Your AC and Dry Summer Air—Some Facts

woman-in-front-of-fan-hand-on-headAs you plan for the warmer weather of the middle of the year, you may not have considered dry conditions. But this is definitely something to think about, since humidity can drop down to “very dry” during midsummer. For example, during July the average morning relative humidity is 39% and the average afternoon humidity is 22%. When relative humidity drops below 30%, that’s considered too dry. (Too humid is when relative humidity is higher than 60%.)

Aren’t Dry Conditions Better for Hot Days?

This is what people usually think when they hear about dry weather in the summer. “It’s hot, but at least it’s a dry heat!” It’s true that the drier the air, the faster heat leaves the human body. This makes the air feel cooler. A 90°F day will feel more like an 80°F day because of low humidity.

However, dry air brings problems with it. It aggravates respiratory conditions, allows for illnesses to spread quicker, creates skin, eye, and nose irritation, and leads to damaged wood and painted surfaces. It’s far better to have humidity balanced around 45% inside a home—it’s ideal for comfort as well as the health of your household and the house itself.

The Air Conditioner Can Make the Situation Worse

There’s no question that air conditioning in Salt Lake City, UT for a house is a necessity. The summers would be unpleasant without one. But an air conditioner makes dry air even drier.

The way an AC cools down a home is by evaporating cold refrigerant along an indoor coil. The coils absorb heat from the air (a natural product of evaporation), which lowers the temperature of the air. That’s good! But it also absorbs moisture from the air, which collects along the coil and drips down into a pan. That’s bad—at least it is if your home already has dry air.

You Can Do Something About This

We strongly recommend installing a whole-house humidifier in the HVAC system to balance indoor humidity. You might recoil at the suggestion of putting in a humidifier for the summer, but this is one of the best ways to control relative humidity and put it at the ideal 45%. Unlike room humidifiers, whole-house humidifiers have precise controls that are integrated into the thermostat. You can adjust humidity so your air won’t be too dry or too humid.

Call IAQ and Air Conditioning Experts

A whole-house humidifier isn’t a device you can pick up at a home supply store and then rig up in your house. This type of indoor air quality system must receive a professional installation to place it inside the ventilation ducts and then wire its controls into the thermostat or its own separate humidistat. To ensure this job gets done correctly and you don’t end up with an overly humid house, arrange for the installation with our experts. We have many years of service to Salt Lake City and the surrounding areas, and we’ll get the job done.
