Gas heating systems are efficient and reliable, but they can be dangerous if not properly maintained. Failing to keep your gas heating system in good working order can also lead to higher heating bills or inadequate heating on cold winter days. Here are a few key signs of a problem with your gas heating system that you should never ignore.
1. Eggy Smell
If you have a gas heating system, it is very important that you can recognise the distinctive scent of gas. This smell is a bit like the odour of rotten eggs.
Smelling gas in your home is a sign that there could be a gas leak, in which case you need to contact a gas heating service right away so they can locate and repair the leak. While you are waiting for the engineers to arrive, do not smoke, light candles or use the stove as the gas in the air could catch fire or explode.
2. Loose Pipes and Tubes
Every so often, it is a good idea to check the pipes and tubes that connect to your furnace. Rust, wear and tear, and other forms of corrosion can over time affect the connections between them.
Gently pull on the pipes and tubes that connect to your gas furnace such as the drainage tube and venting pipe. If you find any loose connections, you need to contact your local gas heating services right away.
3. Blocked Drainage Tube
The drainage tube that connects to your gas furnace allows water created during combustion to drain away. If this tube becomes blocked, your furnace could shut down unexpectedly.
It is usually possible to unblock the drainage tube by disconnecting it and then squirting some compressed air into the tube to dislodge the blockage. However, if your drainage tube frequently becomes blocked, you should have your furnace serviced, as this is a sign that combustion is not happening correctly.
4. Dirty Furnace
Gas furnaces become dirty over time. You can clean out your furnace quickly and easily using a vacuum cleaner. This job is safe to carry out yourself as long as you turn off the furnace and let it cool before attempting to clean it.
If your furnace suddenly starts to produce a lot more dust and dirt than usual, take it as a sign that you should schedule a service. Furnaces that are in perfect condition should burn gas cleanly, producing relatively little dirt. Obtain local gas heating services if you are having issues.
