Why Would a Furnace Need to Be Replaced?
As you probably know, furnaces are machines that help us regulate our home’s temperature by heating or cooling air for circulation through it. Furnaces require both electricity and gas to work and can be of different types: forced-air, hot water, steam, and oil. Modern furnaces have an average lifespan of 15 years.
When your furnace reaches the end of its serviceable life, here are some signs that could indicate it needs to be replaced :
• The temperature fluctuates despite turning up/down all heat settings;
• The system turns on/off intermittently even though you allow a full day in between cycles;
• You notice excessive noise or vibration when the furnace is running;
• The system is leaking, smoking, or the furnace doesn’t turn on anymore;
• You hear a high-pitched noise while the system is running;
• The display screen shows Codes and symbols.
How Long Does It Take to Replace a Furnace?
Replacing a furnace can take around three days, depending on the unit type. While some furnaces are bought preassembled, others come in pieces and require installation by technicians. If purchasing a new furnace yourself, you should read the manufacturer’s installation manual beforehand. This way, you’ll know everything that will be included and what type of tools might be needed (it’s best to gather all necessary parts and tools beforehand).
Replacing a furnace can cost anywhere from $1500 to $3000, depending on the brand and type you choose. If you buy an energy-efficient model, it’ll save you money in the long run as they don’t require as much electricity or gas. Replacing your old furnace with high efficiency (90%+) unit holds around 30% of gas bills every year.
The process of installing a new furnace is easy if done correctly:
• Turn off all power sources to prevent electrical shock;
• Unscrew or detach any wires that connect the air ducts to the system ;
• Take apart all piping/connections by removing screws;
• Clean the furnace’s venting system;
• Disconnect all gas lines that run into the furnace;
• Unscrew or remove anything that holds the furnace in place.
Once your old unit is out, move it to another room and block off the previous location with cardboard boxes to prevent debris from entering other areas of your house during installation. Set up your new equipment to take out the old machine, connect everything back together and turn on all electricity/gas sources.
