Just like any other appliance in your home, the furnace requires proper maintenance and servicing from time to time. Failure to do this, it will malfunction, resulting in a loss of efficiency, higher energy bills, and even safety risks. Here are some signs that it’s time to call a furnace repair technician:
It Uses More Energy
Have you noticed a spike in your energy bills? An older or poorly serviced furnace uses more energy to generate the same heat as a newer unit. The reason is that it’s not burning fuel as efficiently.
It also requires more energy to start up, making your energy bills skyrocket.
Remember that dirt, clogs, rusted components, and other problems cause the furnace to use more energy. If you notice unusually high energy bills, it’s time to call a furnace repair technician.
However, because a high energy bill doesn’t necessarily point to a furnace issue, contact an energy auditor to pinpoint the source of the problem.
It Makes Strange Noises
A healthy furnace is silent, but you’ll hear some noises when it starts and during the operation. But it’s time to call a professional if you notice loud bangs, rattling, and other odd noises. Possible issues are a loose blower wheel, worn fan belt, or blocked vent.
Other problems are igniters, control boards, and components on the brink of failure. Because you can’t tell what’s wrong with the furnace, it’s best to let a professional handle the diagnosis.
It Doesn’t Produce Warm Air
If your furnace doesn’t produce warm air, the problem might be a dirty filter, clogged burners, or other internal issues. It might also be a sign of a failing thermostat or even a gas leak. This is a severe issue as it affects comfort and safety. It should be addressed immediately by a professional. If you suspect a gas leak, switch off the unit and contact a repair technician.
It Has Unusual Odors
When your furnace runs, it produces a particular smell which is normal. However, it’s time to call a technician if you smell rusty, musky or burning rubber. These smells indicate a severe problem, like clogged burners or dirty filters. Sometimes, the odors signal a burning electrical wire. Again, these are serious issues and should be addressed by a professional as soon as possible.
It Cycles Too Much
When your furnace runs, it should stay on until it reaches the desired temperature. If it cycles frequently and shuts off shortly after starting, this could be an issue such as a clogged filter, thermostat problems, or dirty blower wheel. You may also have a failing igniter, control board, or other components. Older units are more prone to these problems.
It Takes Too Long to Heat Up
If your furnace takes forever to heat up, call a professional to inspect it. Simple issues are it’s running at a low flame, or the air pressure is too high. If it still takes too long, it could be a sign of a bigger problem like a malfunctioning control board. It’s a complex issue and requires technical know-how to fix.
The Air Quality Is Poor
Signs of poor air quality are strong odors, excess dust, and fatigue. A dirty filter, clogged burners, or blower wheel can all cause indoor air quality problems. A technician will inspect the system and replace any faulty parts. Additionally, he can recommend ways to improve the air quality.
Always Consult a Professional
The furnace is essential to every home and should be serviced regularly to keep it running efficiently. It will also last longer, reducing repair costs and keeping you safe. If your furnace is exhibiting any of the signs mentioned above, call a professional for an inspection.
