Have you wondered why the air in your home is either too dry or too damp? AC by J can help you answer that question. Take back control of your indoor air quality with whole house humidifiers that help you balance out the moisture levels inside your Tempe, AZ, home. Our team installs whole house humidifiers near your furnace. The equipment goes inside the ductwork on the return or supply end of your system. Air from the ducts goes through the humidifier, picking up moisture from the water inside. The water evaporates and increases moisture levels once it exits the humidifier and flows through the vents. We also offer full house dehumidifiers if the air inside your home is too moist.
