Why Do You Need a Furnace Repair?
If you’re experiencing any of the following problems, then the chances are that your furnace will need to be repaired:
Noisy Furnace Troubleshooting
One of the most common reasons you should have someone check it out is if your furnace makes sounds that seem loud, repetitive, or unusual. While some noises may just come from something being loose, other potential issues shouldn’t be ignored. For example, a squealing sound could mean that the motor’s bearings are wearing down and require replacement, while a rattling noise could indicate problems with either the blower or heat exchanger. If you hear banging noises coming from the unit itself, this means there are issues within its framework, so you want to have it checked out right away.
Incorrect Furnace Cycling
Do you notice that the furnace turns on and off at random times? This could indicate a problem with its thermostat as it might not be wired correctly or calibrated correctly. Suppose there is a constant issue with warm air being blown into your home. In that case, this could mean that the furnace’s limit switch isn’t working correctly, which, in turn, causes it to continue running after reaching a specific temperature. Large electric bills may also point to this problem since the furnace will run without stopping until reaching the desired room temperature. The reason for this is due to how HVAC systems are designed – they assume everyone goes their maximum amount of heat before slowing down, so you might find yourself paying more than what you need to.
A furnace that continues running after reaching its maximum heat output could also mean that the limit switch is faulty, so it doesn’t know when to stop heating anymore. This component has a set point that, once reached, tells the furnace to shut off until room temperature decreases, so it’s usually a good idea to have this checked out right away. You should also consider having someone come by if you notice that your system does not turn on at all as there may be a problem with either the thermostat or its wiring – before calling for a repairer, first ensure that everything is plugged in and turned on. Black-colored marks or burn spots on your wall could be from an overworked blower motor and is a good indication that the unit needs to be replaced. If you’ve already done so, but it continues acting up, then you might want to check out the blower wheel for any abnormalities such as cracks or missing pieces.
