The initial procedure in furnace repair troubleshooting is to understand what type of furnace you have. Is the fuel oil, propane, natural gas or electric? Then how does the heat get sent through the house? Is it forced hot air through duct work, water through pipe work or steam?
A good example would be that you don’t want to take a bunch of time looking for a pilot light on an oil furnace as it doesn’t have one! So if you don’t have much technical knowledge about furnaces then its better left to the pros that are trained on repairing them.
Here are a couple simple tips that most anyone can do:
On a hot air furnace if you aren’t getting the air flow amount you are used to then check the filter to make sure it isn’t clogged.
With a gas furnace there is a pilot light. Make sure the pilot light is lit. If it isn’t then it might need to be cleaned. Also, check that there is sufficient fuel. The thermocouple might need to be replaced.
Check for fuses or breakers that got tripped if applicable. This may be a indication of a bigger problem but check there first.
Other easy checks are the thermostat. Inspect that its turned up. Also, check that the emergency switch didn’t accidentally get turned off. Guests or kids may switch these off assuming they are light switches. I know these sound quite easy but could save a furnace repair visit.
So as you can see there is some easy furnace repair troubleshooting that you can do yourself to thwart off an expensive visit.
