Frequently Asked Questions

Furnace installations depend on multiple factors — not least of which is the size of your home. However, the average cost for a new, fully installed high-efficiency Lennox furnace in Calgary is between $5,500 and $9,000, excluding add-ons. Financing plans are available to spread the upfront costs out over several months and make new furnaces more affordable.

Furnace repair costs depend on the parts and labour time required to diagnose and fix the issue. Alberta Mountain Air usually charges between $100 and $1,000 or more, depending on the complexity of the repairs.  We are transparent with our charges and will provide a reliable estimate upfront.

Typically, furnaces last 15-20 years in Calgary. This will depend greatly on the type and brand of furnace, the quality of the original installation, how often you run maintenance checks, the air quality in your home, and how you use the furnace in your household.

A furnace is a major investment. As such, it needs regular professional maintenance and any repairs should be performed only by licensed technicians. Alberta Mountain Air repair teams are skilled in the safe handling of gas and combustion systems and adhere to all local gas codes and standards for your safety. They will troubleshoot and diagnose issues efficiently to save any additional or unnecessary repairs and any work we do will not negatively affect your product warranty.

It’s common for furnace problems to occur when they’re working hardest, i.e., during cold snaps. A freezing house is not very attractive for anyone so it’s best to call a reliable furnace repair team to get you back and running ASAP. At Alberta Mountain Air, quick response times ensure that you’re not left waiting in the cold.

Most times, furnace repairs make sense over completely replacing a heating system. However, if your furnace is approaching 15 years of service or more and requires frequent repairs, it may be more cost-effective to switch to a high-efficiency furnace that will save you money on energy bills as well as repairs in the future.

Some typical signs that your furnace has a problem include:

  • No heat
  • Cold air coming from vents
  • Higher than usual energy bills
  • Leaking water
  • Loud bangs or unusual noises
  • Unusual or bad smells
  • Turning off and on repeatedly (short-cycling)
  • Unusual cold spots in the home

The furnace installation process typically includes a visit to your home for an evaluation and a quote. If approved, the old furnace will be removed and the new one installed and tested before the cleanup. Our team will also walk you through how to use your new system and answer any questions along the way.

To prepare for this on the day of installation, we recommend you clear the working area and remove any obstructions. Please make sure someone is home when the technician arrives to grant access and check work before finishing up.

The duration of a furnace installation can vary but it typically takes our team one full day to complete an installation.

We recommend yearly maintenance to ensure your furnace is functioning at optimal performance and energy efficiency.

Aside from scheduling annual maintenance with a trusted service provider, you should replace the furnace’s filters regularly to reduce strain on your heating system.

Nearly every furnace manufacturer requires regular (and sometimes annual) furnace maintenance. Without proof of maintenance, the manufacturer may deny your warranty claims, potentially costing you thousands in unexpected repair costs.
