As a homeowner, you want to to make sure that you and your family are never without heat during the winter. To help you with this, you should learn the following signs of furnace trouble. This way, you will know when it is time to call in an HVAC technician.
You Hear Something Banging Around
You might hear the occasional noise coming from your furnace and this is not usually something that you have to worry about. However, the normal sounds should never be loud enough to startle you. If you have found that your furnace is making a loud banging sound, like there is a metal ball bouncing off the sides of the furnace, then you need to call in an HVAC contractor. The problem could be something as simple as a fan motor starting to lock up. It could also be that the furnace is starting to lock up. Either way, these are issues that you are going to want to address right away.
The Pilot Light Keeps Needing To Be Lit Again
If you have a natural gas or propane furnace, you will have a pilot light that needs to stay on at all times when the furnace is in use. You will find yourself without heat in the home every time your pilot light goes out. If you are noticing that you have to ignite the pilot light more and more often, you will want to have a skilled HVAC technician take a look at it for you. There is a good chance that the pilot light simply needs to be cleaned, as the buildup of dirt is causing the flame to go out. This is commonly seen in older furnaces. However, it could also be that the pilot light ignition pieces are malfunctioning and will need to be replaced in order for the problem to stop happening.
The Floor Shakes When The Furnace Kicks On
A floor that shakes when the furnace turns on is not a normal thing and it is not something that you should ignore. It could very well be a sign that there is a build up of gas before it finally reaches the pilot light within the furnace. When the gas finally does reach the pilot light, there is a small burst of flames and the pressure that was built up causes vibrations in the door. You might even notice that the door to your basement will rattle a little. You might simply need the pilot light to be readjusted or it the pilot light mechanism might need to be replaced by a licensed HVAC contractor.
With those three signs in mind, you should have little trouble determining whether it it time to call an HVAC technician for an appointment.
