Furnace, AC, HRV Regular Maintenance

Your Furnace Filter

  • A clogged filter can block airflow and cause costly damage to your furnace.
  • Check your furnace filter monthly & clean (permanent filters only) or change your filter every 1 to 3 months depending on level of soiling.
  • Use the correct size of filter, and ensure your furnace filter fits securely – gaps or spaces reduce the filtration of your air and allow your furnace to get dirty more quickly.
  • If you have two or more furnaces, confirm you are using the right filter size for each – often homes with multiple furnaces will have a larger and smaller furnace with different filter sizes.

Your Humidifier

  • Check your humidifier for leaks every month when you check your furnace filter.
  • Clean (permanent pads only) or replace humidifier pads before winter.

Your HRV (Heat Recovery Ventilator)

  • Vacuum, wash & dry HRV filters every two months during heating season.

Not sure if you have an HRV? It is a large rectangular metal box in your furnace room. Stale or “old” air passes through, and heat from that air is captured to heat incoming cold, fresh air. It also helps to control condensation. There are filters in your HRV on both the intake and exhaust sides of the system.

Air Conditioning

  • Clean dust & debris from outside air conditioning units in the spring, to ensure that function is not compromised.
  • Cover your outside air conditioning unit in the winter when it’s not being used.

Furnace Tune Up

  • Get a licensed heating professional to check and ensure that your system is running safely & efficiently every year.
  • If you have air conditioning, you should make sure that the company you call is licensed to handle air conditioning as well.
  • If you have a concern about any gas appliance, including your furnace and hot water tank, ATCO Gas offers safety inspections.

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!
