Mortgage and Lending with Investment Properties

It is essential to take the time to make sure that your heater is working properly before the winter months come. Not only should you make sure that your furnace is working so that it can keep your family warm, but you should also make sure that it will operate safely as well. Household furnaces can be dangerous if you do not know how to care for it properly. So, how does a furnace work in a house? 

How Does a Furnace Work In a House?

Here are some essential tips from Worlock Air Conditioning on furnace safety that you can apply on natural gas, oil and propane furnaces:

1. Never attempt to repair gas lines or your furnace unit by yourself. It is best to call a professional who is knowledgeable in working on these necessary appliances.

2. The furnace filters should be changed regularly. If you have a disposable one, you can always buy a replacement for it. Permanent filters should be washed or vacuumed regularly. This is important because a blocked filter would cause the furnace not to function correctly and would cost you more than buying a replacement filter. There are different kinds of filters in the market. If anyone in the family has an allergy, you may choose to buy one that eliminates allergens.

3. You should check the blower belt and if needed, oil the blower motor. If your furnace has an old, cracked or loose belt, get a replacement. It would be unfortunate if in the middle of a snowstorm the old belt will not work. You may need to oil the motor, or you can always call up a heating professional to do it for you.

4. The furnace area should always be kept clean because excess dust can interfere with gas flow causing the furnace not to work correctly. Accumulated debris can also start a fire in the furnace itself. Make sure that the furnace is kept clean at all times as foreign materials obstructing the passage will lead to overheating of the furnace.

5. If this is your first time installing a household furnace in your new home, you should make sure there is enough clearance between the unit and the wall, as well, as other household appliances. Since the furnace emits heat, it can ignite a fire from cleaners and chemical solutions if they are anywhere near this machine.


It's key to know, "How does a furnace work in a house?" Instances where once you smell a gas leak in your home at any time, you should get out immediately and call for help. Do not turn on any electric unit or make phone calls inside the house. Lastly, it is best to call a heating professional to maintain and check your household furnace regularly. With these furnace safety tips, you can be assured that during the heating season, you and your family are safe and will be kept warm at all times.
