Your furnace is a key part of your home's HVAC system. For this reason, you need to know when your furnace requires some type of maintenance. By knowing more about a few common issues you can experience, it will be easier for you to identify the cause and repair it quickly.
A burning smell when the furnace turns on is a common issue people experience. The reason behind the smell is that the coils inside the furnace have dust on them, which burns off when the coils heat up.
However, you have a bigger issue if the burning smell comes back each time the system turns on. When this happens, the problem is generally due to a thicker coating of dust that is covering the coil. To deal with this, you need to remove the dust with a stiff-bristle brush and a cloth.
Unfortunately, if the burning smell persists, you need to consult an HVAC technician. Worn out metal parts or frayed wiring can also cause a burning smell when your system turns on. By consulting an HVAC company, you can repair any worn out or damaged pieces in a timely manner.
If your furnace shuts down randomly, this is another sign that your system has an issue. When your furnace shuts off randomly and the cause is not electrical, then it can usually be linked to an issue within the drainage line.
A clogged drainage line is one common reason for a shutdown to occur. When you run your A/C, it creates condensation and this moisture collects in a pan that is connected to your furnace. This moisture is supposed to flow from the pan and into the drainage line, but if there is a clog, then the water has nowhere to go.
Once the water in the pan reaches a specific level, the furnace will shut down to prevent the moisture from harming the electrical system. If the clog is small, then it may allow the water the slow release. In this situation, once the water recedes the unit will turn back on, but as the clog gets larger your furnace will shut off more often.
To deal with this problem, you need an HVAC technician to blow out the drainage line. They do this by pushing air through the line, which in turn pushes the clog out. After the clog is removed, you should not have an issue with your furnace turning off unexpectedly. Contact a business, such as Washam Plumbing Heating & Air Conditioning, for more information.Share
