There’s no doubt you need a furnace repair when you have no heat and you can’t get the unit to reset. But when your Woodbury furnace just doesn’t seem to be working quite right, or it has developed a little vibration or noise, you might be tempted to put off calling for help. Maybe it will heal itself.
Well, heating systems don’t get better by themselves very often, but they can get a lot worse if they are neglected. If the airflow is inadequate, it may be something as simple as a dirty air filter, but it could be a loose or broken fan belt. If the belt is bad or needs adjustment it’s not too difficult to fix. But, it does need to be fixed.
If you hear a strange noise, it could be that the fan wheel has become loose on the motor shaft. A loose fan wheel can make noise even if it is still in the correct position on the motor shaft. Sometimes a loose fan wheel can slide along the shaft and it will scrape on the fan housing. The noise produced can be anything from an occasional ticking sound, to a major grinding noise. In a worse case scenario the fan wheel could jam against the housing causing the motor to overheat. But if no damage has occurred, it’s not a difficult furnace repair. The fan wheel can be repositioned and the set screw properly secured.
If you don’t have it repaired in a timely manner, the fan could be damaged so badly that it needs to be replaced. Also, if not corrected, the set screw could become so loose that the motor shaft would turn inside the fan hub. If this happens the motor shaft and the fan will be damaged and you will have to replace both the fan wheel and the motor. Now you will be facing a rather expensive furnace repair.
The point is, if you detect something unusual happening with your heating system, don’t shrug it off as just a minor annoyance. While it may be a minor fix, there may be an underlying problem that could result in a major furnace repair, or even necessitate a furnace replacement if not attended to in a timely manner.
When you have a major breakdown of your heating system, it’s probably not going to happen some morning when it’s 70 degrees outside; It will more likely be when it’s 20 below and 9 o’clock at night.
Fortunately, faults with heating systems are not a frequent occurrence, but when they do happen it can be a major inconvenience, and quite expensive. The best way to avoid needing an emergency furnace repair is to have a regular preventive maintenance program which provides scheduled inspections and routine adjustments to your system.
