SIGNS THAT YOUR FURNACE
NEEDS TO BE REPAIRED
 Lack of Maintenance
 Similar to owning a car, if the furnace isn’t getting regular maintenance done it won’t last very long. A
furnace requires that a certified HVAC professional inspect the furnace as often as once a month.
 The Furnace Stops Working
 If the furnace just stops working that is usually a tell-tale sign that a repair may be needed. The usual
reason why a furnace stops working is because the filter is clogged with dirt and debris. If the furnace
filter is clogged then the furnace may shut off and the heat exchanger may be damaged as well.
 Old Furnace
 Sometimes older homes may need any number of things repaired. The furnace might be one of them.
One of the signs that can determine if a furnace needs repair is just by the looks of it. Does it looks like it
has gone through a huge amount of wear and tear? Does it look like it’s going to fall apart at any given
moment?
 The Furnace Smells like Gas
 When the device smells like the exact same thing that is fuelling it, that is a sign of a leak. When a
furnace smells like gas, it is leaking. This is a sign that a repair needs to take place. If your furnace
exchanger begins to leak your home can be in for all sorts of problems.
 Pilot Light Color Changes
 Similar to a smoke detector, a car or just a computer screen, when there is an issue the pilot light will
change colors. When the furnace is working fine the pilot light should be the color blue. Generally when
there is a ventilation problem with a furnace the pilot light will turn yellow.
