Indoor Comfort Guide Whole-Home Humidifiers in Arizona: Are They Worth It?

By My AZ Pro Heating & Air Conditioning · Husband-and-wife owned, 30+ years of HVAC experience · Updated

Arizona air is dry most of the year, and it can get even drier indoors in winter when the heat is running. A whole-home humidifier connects to your heating and cooling system and adds moisture to the air throughout the house. For some homeowners, especially those dealing with dry skin, irritated sinuses or static shocks, it can make a noticeable difference.

Signs your indoor air is too dry

  • Dry, itchy skin or chapped lips
  • Irritated sinuses, nosebleeds or a scratchy throat in the morning
  • Frequent static shocks
  • Wood furniture or floors cracking or separating
  • Houseplants that struggle indoors

How a whole-home humidifier works

A whole-home humidifier is installed on your air handler or ductwork and adds moisture to the air as it circulates. Unlike portable units, there are no tanks to fill in every room. It connects to a water line and is controlled by a humidistat so you can set the level you want.

Is one right for your home?

Most homes do well with indoor humidity roughly in the 30 to 50 percent range. In the desert, winter humidity can drop well below that. A whole-home humidifier makes the most sense for homeowners with ongoing dryness symptoms. Too much humidity can cause problems of its own, so proper setup matters. Call us to talk about whether it fits your system.
