We live in a country where the temperature is in the negative column for a large portion of the year. As Canadians we rely on our furnaces to keep us warm during those long, cold winter months. When you understand why having a preventative maintenance schedule helps to keep your furnace not only running but working efficiently, you’ll want to add it to your routine. Furnaces are generally located in basements and that means there’s a dust accumulation. Try as you might to keep things clean downstairs, a dust build-up of 1/8 inch on blades and shutters can affect the performance by as much as 30 per cent. You could clean it yourself, but having a professional perform annual maintenance means that any frayed electrical connections or problems with the ductwork will be noticed too. The cost of energy is high enough these days and you don’t want your equipment adding to the expense. Dust that’s built up on safety grills or shutters can further restrict a fan’s performance and add to premature motor burnout. Experts understand all the impediments to smooth operation when it comes to the furnace motor and how all the elements are connected. Cleaning the burner and flame sensor are other common techniques you get with annual preventative maintenance. The right adjustments can be made by running the system through an entire cycle and will determine if there are any carbon monoxide problems. Scheduling preventative maintenance on your furnace every year is a great way to make sure this unit operates at peak performance and runs safely through the winter season.
