Signs That You Might Need A New Furnace

Posted in Furnace Installation

Modern gas furnaces are expected to last 10-15 years. With proper maintenance however, they can last much longer. If you have an older furnace there are some good reasons to upgrade to a new one. But how do you know when it is time? What are some signs that you might need a new furnace?


Furnaces have a few moving parts that in time will wear out. When they do, the first signs that they are failing is noise. Induced draft motors and blower motors have internal bearings that will begin squealing when they are worn out. Often the expense of changing them is unjustified compared with the cost of a new furnace. That is, if your furnace has other issues or is very old.


Are you noticing black or grey stains on ceilings or walls where registers are located? If so, this could be an indicator of a heat exchanger breach. Products of combustion should never leak into your home or office. Even a small amount of carbon dioxide from a broken heat exchanger can snowball into a carbon monoxide tragedy. If your carbon monoxide detector goes off, or if you suspect fumes from your furnace, call a technician (519 Furnace) for an inspection.


Over time a furnace can loose efficiency especially if not maintained. Dust can prevent proper airflow across the heat exchanger either from coated fan blades or clogged filters. Gas valves can loose calibration and cause incomplete combustion. Sensors like thermostats and thermocouples designed to promote steady state combustion can lose their sensitivity. The bottom line is, if your gas and electric bill keeps increasing, your HVAC system may need an upgrade.

Electrical Issues

Most electronic components on HVAC equipment will either fail in the first week or not at all. If there are any electrical defects in HVAC appliances, they are usually obvious. If an aging furnace starts to give you electrical issues like circuit board or relay failures than prepare for more problems. Electronics are usually the last to fail. A new furnace is less expensive than replacing multiple electronic devices and outdated sensors.
