Signs Your Furnace Needs Repair
Your furnace gives clear warning signs when something’s wrong. Here’s what to look for:
Strange or Strong Odors Coming From Vents or the Unit
Rotting or burning smells can indicate a malfunction or even foreign materials or debris in the system. Strong odors are often a sign of a severe issue and may even be detrimental to your health.
The Furnace Begins to Run Louder
From unnatural grinding to excessive effort, older or damaged furnaces can become louder when they aren’t working properly. This is a sign that a furnace is operating less efficiently and should be fixed.
Higher Energy Bills
Furnaces can lose operational efficiency over time, but if your system is under 5 years old and already showing signs of inefficient energy use, it may not be just normal wear and tear.
Irregular Heating Cycles
If you notice cool zones in your home or odd start-ups and stoppages from your furnace, it’s time to consult a technician.
Continuous Running
In line with higher energy bills, a furnace that runs continuously (or “cycles”) is experiencing one or more issues that are impacting its ability to efficiently and completely heat your home.
Leaking Fluids
Whether it’s a clog or a break in a line, fluid buildup, or leakage around a furnace is a sure sign that a repair is necessary.
Discrepancy in Your Thermostat Setting and Real-Feel Temperature
While this could be a thermostat issue, it could also indicate that your furnace can no longer effectively heat your home. If the latter is the case, a technician can help determine whether your furnace needs repair or replacement.
Carbon Monoxide Safety
We always recommend keeping a carbon monoxide detector near your gas furnace to alert you to potential leaks. If you ever smell gas or suspect a carbon monoxide leak, here’s what to do: turn your furnace off immediately and leave your home. When you’re safely away from the potential leak, call for emergency service. Leave the repair to us; this isn’t the moment for a DIY fix.
