Humidifier Pad Replacement

  1. Do I need to replace my humidifier pad, or can I just wash it?
  • Flow-through humidifiers have a pad that needs to be replaced generally about 1x per year, as they become encrusted with deposited minerals from the water.
  • Humidifier pads should be REPLACED and NOT washed, because the pad may have a hydrophilic (absorbent) coating or anti-bacterial coating that wears off with washing and over time.

  1. How often should my humidifier pad be replaced? 
  • You should check your humidifier every 30-60 days for visible signs of build up.
  • Generally it is recommended that pads are replaced once per humidification season – which if you usually only use your humidifier in winter, would be once per year.
  • This does depend on how much you run your humidifier, and how hard your water is, which is why checking it every month or two is your best course of action.
  • TIP: add a monthly reminder to your phone to check both your furnace filter + humidifier pad

  1. Can Alberta Furnace Cleaning replace my humidifier pad? 
  • We are pleased to sell and install replacement pads that fit most styles of flow through humidifiers. We offer this service as an add on to our regular furnace & duct cleaning services.
  • Unfortunately due to the many models, manufacturers + ages of humidifier units, we are unable to guarantee that we stock a pad for your unit
  • When we replace the pad, we will also do a visual inspection and simple test to confirm the unit is functioning. 
  1. Can Alberta Furnace Cleaning clean my humidifier? 
  • While we will do our best to wipe around the area and ensure water flow in your humidifier, our humidifier pad replacement service DOES NOT include a full cleaning on the unit
  • Cleaning your humidifier usually requires a soak and scrub involving vinegar or CLR to remove mineral build up

  1. Can Alberta Furnace Cleaning repair or replace my humidifier?
  • We do not perform repair, maintenance or cleanings to the humidifier unit itself
  • It is recommended that from time to time you visually inspect your humidifier to ensure there is not excessive build up of scale in the unit, and that all parts are working as intended
  • You should consult the user guide for your specific make and model for maintenance/cleaning instructions

Alberta Furnace Cleaning Reviews

Andrew led a team total of 3 to clean my furnaces on Sep 4th 2025. The whole cleaning process was very well organized, smoothly completed within 2 hours. They are very professional and use the proper tool to make sure all ducted were properly cleaned.

10 out of 10! I cannot express the detail and outstanding service that the whole team put into this endeavor. From the friendly easy booking over the phone, to my amazing in house cleaning team Ha and Lorenzo. They went above and beyond what was expected and ended up fixing an 8 year old dryer vent issue. It was difficult and those 2 would not give up. I will recommend this company to everyone!

AB Carpet and Furnace cleaned our furnace and vents on Jan 30. Ruzle and Tiq were a great team as they quickly and efficiently cleaned our home. They were respectful and courteous, and I would highly recommend this duo to others. The team arranging the appointment was also wonderful as they made booking the appointment simple, and kept me well informed of the arrival time of the cleaning team. Much appreciated!

I can't say enough about the service I received from Alberta Furnace Cleaning. They came today to clean my furnace vents and my in-house VAC system. My Vents were almost completely clogged with construction materials leftover from when the house was built. We also have two kitties and they contributed to the overall blockage. My furnace is already working at a much more efficient level. Alfredo and Joseph were knowledgeable, polite, and efficient. They left my house and furnace room immaculate before they left. Thank you for the great service!
