As soon as you notice that the general temperature of your house is continuously dropping, there is a great chance that your furnace has stopped working. There are various reasons behind this sudden breakdown. Usually, these problems warrant various types of furnace repair. While some of the furnace unit problems may be fixed using simple methods, you are not advised to try them. This is because most of these problems need to be addressed using extensive knowledge and a high degree of accuracy. If you attempt to address these problems yourself, you run the risk of compromising your safety.
One of the most common problems requiring furnace repair in Lancaster is a blown fuse or a tripped breaker. When your fuse breaks down, your furnace indefinitely stops working. This usually happens when your furnace is required to work more than the ideal duration. Also, the electrical ignition that may occur on the blower or other electrical components of the furnace may cause the entire circuit to break down. When this happens, you should immediately check the panel of the circuit breaker. While you are waiting for your contractor to attend to the furnace and the fuse, you may turn off the switch for the furnace first. Aside from that, you may disconnect the fuse that directly connects to the furnace. For this job, your Lancaster HVAC contractor will need to install a new fuse. Therefore, it is better if you have this part ready before the contractor comes over. After the appropriate furnace repairs are done, you can expect the furnace to be running efficiently again.
Usually, Lancaster gas heating furnaces use a small pilot light or flame to create the main source of heat. This pilot light helps in maintaining the proper gas flow to the furnace. There are various reasons that a pilot light breaks down. One of these is the interruption of the gas flow. A draft in the gas flow may also cause the gas flow to be delayed or completely blocked. When this happens, you need to contact a contractor to perform relighting of your furnace pilot. Before your contractor attends to the pilot light, you may help out by turning off the main power source of the furnace. The recommended method is to turn this off at the thermostat. After extensive furnace repairs have been done, you can determine if the pilot light is properly working if the flame from the furnace remains lighted after you held the knob of the gas valve for around a minute.
Another problem that you may encounter with your furnace is the presence of a dirty furnace filter. This is one of the common problems because your furnace depends on it every time you turn on the entire unit. When you turn on your heating unit, air starts to circulate through the main part of the furnace as well as the vents. Along with the air comes the debris. Various debris and dust particles can be stuck on different parts of your furnace. In the long run, the dust particles can significantly block the pathways where air circulates. When this happens, you may start to notice the decrease in heating levels that your furnace provides. For this concern, you have to contact your Lancaster HVAC contractor to perform filter replacement as soon as possible.
