4 Things You Should Know About Furnace Humidifiers

  1. What does a humidifier do? 
  • A furnace mounted humidifier adds moisture to the air that your furnace distributes through your supply (sometimes called “hot air”) ductwork.
  • Water comes into the unit through a tube and depending on the type of unit, air is flowed through a pad, a sponge, or discs, before being sent through your supply ducts.
  • This increases the moisture content of the air, which can improve comfort especially in dry Alberta winters.
  1. What are the types of humidifiers? 
  • Flow through – this is the most common type. Water moistens an evaporator pad. Air is flowed through the humidifier to absorb moisture from the pad and then is blown through the return or “hot air” system to provide moisturized air to the house. 
  • Drum Humidifier – there are several types of drum humidifiers – older style with a sponge that rotates and becomes moist, with air passing through it to pick up the moisture. Newer styles have multiple disc and no pads or sponges.
  1. Why should I pay attention to my humidifier?
  • A functioning humidifier with a clean pad is critical to maintaining good moisture in your home
  • To prevent potential damage to your furnace, you should regularly check your humidifier
  • Humidifier leaks (and damage to your furnace) can be caused by water feed tubes that become clogged, brittle or loose
  • Failing to replace your humidifier pad, and failing to inspect and clean your unit as needed can also result in leakage which could damage the electrical components of your furnace

  1. What should my humidifier be set at?
  • The Health Canada Healthy Home Guide recommends keeping humidity levels between 30-50%
  • Low humidity may aggravate skin allergies and contribute to or exacerbate respiratory infections.
  • High humidity can lead to mould.

Alberta Furnace Cleaning Reviews

A big shout out to Andrew and Aaron from Alberta Furnace Cleaning. My husband and I had recently renovated our home and were noticing a fine dust on everything that I couldn’t keep up with. Andrew and Aaron came in and cleaned the furnace, air conditioning unit and all the duct work. It was shocking to see what the found - construction debris, dog toys, tennis balls etc. They definitely have the equipment to thoroughly clean the mechanical and duct work. Both workers used care in removing vent covers, and cleaned all surfaces, properly replacing the grills when done. They were on time, efficient, polite and respectful of ourselves and our home. I could not be happier.

I recently have my furnace and ducts cleaned. The two technicians were very professional, thorough and careful in their work. They ensure that nothing was missed and that any debris was cleaned up prior to departure. I know it's not the cheapest option out there for duct cleaning, but I went with a cheaper company a few years back and it turns out that company completely missed one of my cool air intake ducts to empty. Alberta Furnace sucked out A LOT of debris missed in that one duct. You get what you pay for and for their price (which is reasonable) you will get top service. 5 stars!

I had Lei and Dillon from Alberta Furnace Cleaning come to my home yesterday and inspect and clean both my furnaces and 25 vents. They both wore booties in my home and laid down blankets to protect my floors and carpets. I was very pleased with the results and now have some peace of mind.
