Like many homeowners, you probably use an air humidifier in the winter when the combination of low outdoor humidity and running the furnace makes your indoor air uncomfortably dry. While your air conditioner is running all the time during the summer, you may not know that a humidifier can also help combat dry air. Your heat pump or air conditioner cools down your interior spaces by removing heat from your home’s air supply. The condensate drain also removes moisture from the air and sends it outside as a liquid. Having a cooling system that’s efficient at dehumidifying can result in an uncomfortably dry environment. By adding a whole-home humidifier to your HVAC system, you can set your desired household humidity level right at the thermostat, so that just enough moisture is added to your conditioned air. If the humidity level falls too low in the summer, you can also relieve comfort and health concerns, protect your home, and avoid static electricity problems. There will be less discomfort from dry-air problems such as brittle hair, itchy skin, sore throats, nosebleeds, sinus problems and headaches. You’ll also experience fewer colds, flus, and upper respiratory infections since many bacteria and viruses thrive in dry conditions. Excessively dry air pulls moisture from your home’s finishes, such as paint, drywall, wood floors, and trim, causing them to shrink, crack, and warp. Additionally, wood furniture, artwork, musical instruments, and books can be damaged or destroyed by this. Another painful symptom of dry air is static electricity. Random zaps of electricity can permanently damage any device with a semiconductor, such as televisions, computers, gaming consoles, and cell phones.
