Many of the things that go wrong with a furnace happen out of sight, inside the HVAC unit and the ductwork or elsewhere that you cannot easily access. This leads many homeowners to be unaware that they have issues with their furnace, potentially enabling these issues to become worse before they are able to get furnace repair services in Nashville.
Fortunately, there are several signs that can indicate you have a problem with your furnace and should call a local repair company. If you notice any of these signs of furnace damage this winter, your best option is to schedule HVAC repair.
Signs that a Furnace is Malfunctioning
While you often will not see what is causing a furnace to malfunction, signs can generally be clear if you know what to look for. These signs include:
- No Air – When your heater is on, it should blow air out of the vents. No air can be an issue with the furnace itself or caused by a blockage somewhere in the duct system.
- Only Cold Air – If your furnace is set to heat but cold air or even lukewarm air is all that is coming out, there could be a range of problems such as refrigerant leaking, a clogged air filter, or pilot light that has gone out.
- Strange Noises – Furnaces are not completely quiet but any noise that is different from what you usually hear is cause for concern. Rattling, squealing, grinding, and other similar noises are often caused by parts banging together, a lack of lubrication, or something that has come loose.
- Dust Coming from Vents – You should expect a little bit of dust and a slight smell when you turn on your furnace for the first time in the winter as it will have built up over the year. However, if you see excessive dust there could be a problem with your air filter. This problem is also a cause for concern in many families, as this dust can contain bacteria, allergens, and mold spores.
- Age – This is less of a sign and more something you want to stay aware of. As a furnace gets older, it will naturally need a little more upkeep to ensure it is running properly. Although you may not have noticed particular issues, scheduling a furnace maintenance service on an older system can check for worn out parts, dried lubrication, and other issues that may cause more expensive problems.
Another place to look for signs of potential damage to your furnace is in your energy bills. A malfunctioning furnace will often have to work harder to accomplish the same results, using either more electricity or gas and resulting in higher repair costs or higher utility bills for your family. If your energy costs have increased out of proportion to how often you are using your heat, the cause might be your furnace.
