Winter is just around the corner, meaning your home’s furnace may see much more use. The last thing anyone wants in the middle of winter is to come home after a long day only to discover their furnace isn’t working properly. Accordingly, homeowners should ensure their furnace is in good working order ahead of the winter season. Below, the experienced HVAC technicians with our heating repair company outline six signs your furnace may need a tune-up.

No Heat Is Being Generated
Obviously, this first sign is a dead giveaway. If your heating system can’t adequately warm your home to a comfortable temperature, there’s a good chance your furnace needs service. As soon as you notice no heat is being generated in your home, don’t hesitate to contact our heating company for furnace repairs!
Unusual Noises
While some noise from your furnace can be normal, the sudden onset of abnormal noises is cause for concern. Specifically, some concerning noises to listen carefully for include the following.
- Dripping
- Hissing
- Groans
- Grinding
- Humming
If you hear any of these noises, your furnace may need to be serviced by an experienced furnace technician.
Strange Smells
When you first turn your furnace on for the winter season, it’s completely normal for a faint burning smell. However, some smells could indicate a problem coming from your furnace. If you notice a strong foul smell during or after running your home’s furnace, the best course of action is to contact your local HVAC company for furnace repair services.
Increase In Utility Bills
A sudden spike in your utility bills during the colder months could be due to your furnace not operating at peak performance. If a furnace has some kind of issue negatively affecting its efficiency, it will have to work harder and end up using more electricity. If you notice your utility bills have increased dramatically during the winter season, contact an HVAC technician to check out your furnace.
Yellow/Orange Pilot Light
The pilot light is a relatively simple indicator of a problem and should be checked if you have noticed one of the aforementioned signs. If everything works as it should, your pilot light should burn blue, not orange or yellow. Call a heating technician if there's anything but a blue flame in your furnace's pilot light.
Repairs Are Needed Often
Any time you have to repair a mechanical system often, it’s a sign it’s getting too old. If you’ve had your furnace repaired multiple times in the recent past, it might be time to replace your furnace before you waste any more money on repairs or the furnace gives out completely.
