I'm afraid my old furnace will quit in the middle of winter, is it worth replacing before it breaks down?
Being left out in the cold in the middle of winter when your old furnace quits is definitely something you want to avoid. If your contractor is suggesting that your furnace needs replacing it is wise not to delay. If it's the cost of replacing your old furnace that’s making you hang on, consider that some older models of furnace deliver only 55% of their heat to your home while a new high-efficiency natural gas furnace may deliver up to 97% of the heat it creates to your home. Your old furnace is probably costing you money. Your new natural gas furnace will likely save you money.      Top


I have a limited budget but I am very impressed by the energy savings a high-efficiency model could give me. What should I do?
A high efficiency furnace will have a lower operating cost than a mid-efficiency furnace but will have a higher purchase price.      Top


What will I do with my old oil tank when I switch to natural gas?
You’ll enjoy more space! Your HVAC contractor will take care of removing your oil tank from your basement. Be sure this is in the estimate you agree to. Make sure your oil filling connection is completely removed or permanently closed.      Top


Is there a "best time" of the year to purchase and install a new furnace?
The best time of year to purchase and install a natural gas furnace is in the spring or fall. At these times of the year, contractors are less occupied with emergency service work.      Top


I heat with electric baseboards and am paying far too much for heat. I feel it will be too expensive to switch to natural gas and install all that duct work. Any suggestions?
The cost of the ductwork in addition to the new furnace needs to be calculated over the long term compared to the cost of staying with electric for home heating. Ask your contractor about options such as high velocity duct systems.      Top


I’ve started hearing that we should use natural gas wherever possible instead of electricity. Why is this important?
If you live in Ontario, you may have heard that there are continual warnings that our electrical grid is being stressed. Reducing the load on the electrical grid by using fewer electrical products is the best and easiest way to ease the strain. Choosing natural gas to heat your home instead of electric is a simple and effective way to use less electricity. Considering heating represents 40-60%[1] of your energy bill, switching from electric heating to natural gas heating will help to reduce the load on the electric grid. You will see an immediate reduction in your energy bill. See energy cost comparisons of operating costs.      Top


Will my new high-efficiency furnace affect my water heater choice?
It may. If you choose a high-efficiency furnace you will need to consider the venting requirements of your choice. Ask your contractor for more information.      Top


I want the quietest furnace possible, I sleep very lightly and am easily woken when the furnace comes on.
Choose a two-stage high-efficiency furnace for the least amount of fan noise.  This type of furnace has a fan that operates on a low setting most of the time. It only increases the speed to a higher level when a higher heat demand is necessary. The result is quiet operation and a better night’s sleep for you.      Top
