Question: How often should I have my furnace checked?

Question: How will I know if my furnace is safe?
Answer: Have your furnace checked at least once a year. Especially older furnaces are vulnerable to failure. If a heat exchanger should crack, carbon monoxide can leak into the air in your home. This can be very dangerous and can even cause death since you can’t smell or see it. It is particularly dangerous at night as you sleep.

Question: My furnace smells like something is burning when I first turn it on in the fall. What causes this?
Answer: When your furnace fires for the first time, it burns off the dust and lint around the heat exchanger causing the burning smell. This is one reason you should have your furnace checked and cleaned each year before the heating season.

Question: If I turn my thermostat way down at night. Will I save a lot on energy costs by doing this?
Answer: No. You should never vary the temperature more that about 5 degrees. If you swing the temperature much more than 5 degrees, your house, furniture, walls and floors get cold enough that it takes more energy to heat them back up than it does to maintain a 5-degree swing. Find a comfortable temperature and don’t vary it a lot.
