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.

Having trouble finding the correct size of furnace filter for your furnace? We can help with standard and custom sized permanent filters, disposable filters and pre-filters – contact us.

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.

Just had our first furnace cleaning appointment, and the service was excellent. It was quick, and everything was explained clearly and in detail. The technician wore shoe covers, which I really appreciated since I have small kids at home. The air in the house feels noticeably fresher right away. I’m really happy we got this service done.

Just wanted to say that, first - you guys are awesome! And second - Anjohnel and Mykhailo are fantastic! They came in, explained everything, gave us a few tips and thanked us for being prepared in terms of moving things out of the way for then. They even took some time out to give our dogs a pet, which they really liked! Very pleasant to deal with and payment was quick and easy. Thank you again! For sure we'll be recommending you and will be back once our next service is due!
