How to Tell if You need a Furnace Tune-up.

mid-efficiency furnaceWhile it’s recommended that you get a furnace tune-up annually, do you know the signs that your furnace needs a tune-up now? There are few tell-tale symptoms that will let you know if something is wrong.

1) No heat

Test your furnace before it gets cold to see if it’s putting out any heat. Check the corresponding circuit breaker’s on/off switches first before making a service call. If your furnace is on but isn’t producing heat, call a qualified HVAC company to perform a furnace tune-up for you.

2) Carbon monoxide monitor goes off

Every household that uses gas appliances should have a carbon monoxide monitor. Carbon monoxide, is known as the “silent killer” because it’s indiscernible to the five senses and can be a lethal poison.

If your carbon monoxide alarm goes off you need to:

  • Shut down your gas appliances
  • Open up your windows to bring in fresh air
  • Leave your house & call the fire department
  • Call a professional HVAC contractor to test all your gas appliances–especially your furnace– to see if they’re venting exhaust correctly

3) Utility bill suddenly increases

It’s normal for your energy bill to increase during the winter because your furnace is working more. However, if you see an unusual spike in your bill (even by winter standards) and there has not been a change in utility rates, then your furnace may be in disrepair and you may need a furnace tune-up.

4) You hear a loud banging noise when your furnace turns on

Your furnace should be relatively quiet when it’s running, but if you hear a loud banging noise when you turn it on, your blower motor might need to be repaired or adjusted. Or your furnace ignition could be delayed, which can be dangerous.

5) Furnace produces a strong fuel smell

It’s natural for an oil or gas furnace to produce a faint scent of burnt fuel. But if you’re smelling the strong rotten egg smell of un combusted gas in other rooms and the smell originates from your furnace, you have a serious gas leak that needs to be looked at immediately.

If you smell gas, leave your house immediately and call the your gas company from a neighbor .
