Many people believe that a broken furnace is one that no longer works, but this is not necessarily the case. Mechanical failure isn’t the only sign that your furnace needs to be repaired; there are also subtle signs that it’s broken, even though it looks to be operational. If you see one or more of the symptoms listed below, you should contact an HVAC professional as soon as possible since it could mean that your furnace needs to be repaired.
The unit is making an unusual noise
There isn’t such a thing as a completely silent furnace. It’s likely that you’re having technical problems with your furnace because it lacks ignition, has a damaged belt, or has a wear and tear component that has to be replaced soon. If the noises you hear are not caused by a furnace, you should call the Ghostbusters rather than an HVAC company (laughs).
Your thermostat should be set higher than usual
When their home doesn’t heat effectively at the end of the winter, many homeowners are tempted to boost the thermostat setting. When the condition worsens, even the maximum setting may not give enough warmth. Before it reaches this point, you should have your home evaluated by a furnace repair technician. A malfunctioning thermostat, an intermittent problem with the pilot light, or even leakage in the air ducts could all be the source of the problem.
Why are your energy bills so expensive
If your winter energy bills are excessive, it’s possible that the heat aerators aren’t working properly or that you’ve raised the thermostat owing to insufficient heat. Your furnace may also be inefficient because of a clogged air filter, leaking ducts, or anything else. Rather than wasting money on utility bills, hire a specialist to take care of this.
A yellow pilot light is turned on
If the pilot light on your furnace turns yellow when inspected, it could indicate the presence of carbon monoxide. Blue flames indicate that the gas composition is normal, however yellow flames suggest that it is not. When carbon monoxide is found, a professional can evaluate if the issue is with your HVAC system or your home.
Trouble getting the unit to work or keeping it running on
A malfunctioning thermostat, a wiring problem, or a problem with your pilot light may all contribute to a furnace that takes a long time to turn on, or that begins to perform normally after starting on, but suddenly shuts down. The distribution fan motor could also be faulty. Furnace difficulties that refuse to turn on, like many other problems, frequently deteriorate over time.
Even if your furnace appears to be operating, there are subtle symptoms that it is broken. A faulty thermostat, an intermittent problem with the pilot light, or air duct leakage could all be the root of the problem. You should have your home assessed by a furnace repair specialist before it reaches this point. When inspecting your furnace, if the pilot light goes yellow, this could indicate the presence of carbon monoxide. Your furnace could also be ineffective due to a clogged air filter, leaking ducts, or other factors. Rather than squandering money on utility bills, pay a professional to handle this.
