There are a number of different things to consider when it comes to furnace repairs and troubleshooting, the first thing to understand however, is what your gas furnace actually is and what it looks like. Essentially, a gas furnace is a device that looks like a large box that takes in cold air, then cleans the air with a filter, then heats up the air with a gas burner by means of a stainless steel heat exchanger. It then finally distributes the warmed air with a motor that blows all the warmed air throughout your home’s duct work.
What then happens is, the air that has been heated then cools down in all the different various rooms of the home and then returns to the source – which is the furnace, through the duct work and air grills that are present in each room. The cold air then returns through the air filter into the furnace and is then prepared for another heating loop. In some cases there is a humidifier that is mounted on the furnace as well or on the air duct work. Also keep in mind that different furnaces are measured on their efficiency with a standard known as AFUE.
Once in a while some of the functions may not be working quite the way they showed any might need to troubleshoot this device, one of the more common types of things that people often have to replace or repair is the standing pilot if it has one. Typically, most of the modern furnaces that are installed in most homes use a form of electronic ignition and need different types of troubleshooting that tend to be a bit more complicated depending on the sophistication of the actual furnace itself. Let’s consider some of the more common types of problems and repairs the likely going to encounter.
The most common type of issue that most gas furnaces usually have is that they simply do not produce any heat, or at the very least any discernible heat. There are number of different reasons why this could be the case, some of the most common is the thermostat being set too low and is therefore not asking for heat or the thermostat might not be working at all. Another issue that might come up is that a circuit breaker or fuse that is controlling the furnace has been blown or tripped, in cases such as these, you might want to consider hiring a furnace repair specialist. These specialists are able to take a great deal of the stress of repairs out of the equation..
If you find that you are comfortable at least troubleshooting some of the issues yourself, you might want to consider reading a relevant website for additional tips. Some of the recommendations they might suggest architect thermostat and see if it is in “heat mode “and has the appropriate temperature setting. Another suggestion they might give if there is no heat being blown through the heating system, is to try adjusting the actual dials setting up or down a few degrees.
