Stage 1: Assess Your Current Gas Usage


Before tearing out your old equipment, you need to understand exactly how much energy your current setup is wasting. Evaluating your baseline performance helps justify the investment in modern technology.


  • Review Past Utility Bills: Pull your gas bills from the previous January and February to see the exact financial peak of your winter heating costs.
  • Check the Exhaust Pipe: Look at the flue pipe connecting your furnace to the chimney, as a hot metal pipe indicates a significant amount of your paid heat is escaping outside.
  • Monitor Run Cycles: Listen to how often your furnace turns on and off on a chilly day, because rapid cycling points to severe mechanical inefficiency.
  • Find the AFUE Rating: Locate the yellow energy sticker on your existing cabinet to see if you are operating on an outdated eighty percent efficiency standard.


Stage 2: Schedule a Professional Sizing Calculation


Installing a top tier furnace requires absolute precision. You cannot simply swap an old box for a new one without recalculating the thermal needs of your house.


  • Book a Home Walkthrough: Have a licensed technician evaluate your window quality, insulation thickness, and total square footage.
  • Demand a Manual J Load Calculation: Ensure the contractor uses strict mathematical formulas rather than guesswork to determine the exact BTU output your home requires.
  • Discuss Venting Options: High efficiency furnaces require specialized PVC venting installed through the side of your house, so you must map out a safe exit route for the new exhaust pipes.


Stage 3: Protect Your Budget Before the Freeze


The window to perform a comfortable and proactive installation closes rapidly once the snow begins to stick in Sutherland. Locking in your project now avoids the panic of an emergency replacement.


  • Secure Financing Plans: Take advantage of our flexible financing options to spread the cost of the upgrade into manageable monthly payments.
  • Schedule the Installation: Book your installation date immediately to guarantee your new equipment is operational before the extreme cold warnings hit.
  • Apply for Rebates: Work with your contractor to submit the necessary paperwork for any local SaskEnergy rebates available for high efficiency upgrades.


â–º The single most important urgency fact is that waiting until your furnace completely fails in December means you will pay a massive premium for emergency, after hours installation services.


Frequently Asked Questions


Does a high efficiency furnace run all the time?


Modern variable speed furnaces are designed to run for longer, continuous cycles at a very low capacity. Instead of blasting your house with intense heat and shutting off, the system gently circulates warm air to maintain a perfectly consistent temperature. This low and slow approach uses significantly less gas and electricity than an older single stage motor.


How much does a high efficiency furnace actually save?


Upgrading from an old sixty percent efficient pilot light furnace to a modern ninety six percent efficient model can cut your heating portion of the gas bill by nearly a third. Over the course of a ten to fifteen year lifespan, these monthly savings often cover the entire initial cost of the premium equipment.


Why do high efficiency furnaces need PVC exhaust pipes?


High efficiency systems extract so much heat from the combustion process that the resulting exhaust gas is actually cool to the touch. This cool exhaust vapor condensates into a highly acidic liquid that would quickly rust and destroy a traditional metal chimney. Thick PVC piping safely vents this acidic vapor outside and allows the liquid condensate to drain harmlessly away.


Making the Smart Heating Choice


Lowering your winter energy bills starts with making an informed decision about your mechanical equipment. By assessing your usage and scheduling a proper installation now, you take full control of your winter comfort.
