Common Furnace Problems and How to Fix Them
A furnace is one of the most efficient ways to heat a home. Depending on the type of fuel source you use, a furnace can also be incredibly eco-friendly. How does a furnace work? Basically, a furnace is powered with a motor that has an ever-burning pilot. When the furnace is turned on, the pilot light sparks and powers the unit. In most cases, a series of ductworks will carry the heat and warmth created by the furnace to each room in your home. However, a furnace is not impervious to a number of issues that can arise. These issues become especially prevalent during the months when you are relying on the furnace the most, which can be especially frustrating. Here are some common furnace problems and how to fix them.
- Make sure that your thermostat is on and in the right position. In some cases, a broken furnace may not be a broken furnace at all – it may be an issue with your thermostat. If you tried adjusting the temperature, but nothing happened, it could be that you didn’t put the thermostat in the ‘heat’ position. This is an understandable mistake to make – especially after a long summer.
- Make sure the thermostat has batteries. Another thermostat issue may have to do with the batteries. If your thermostat isn’t turning on at all, it means that you need to take the faceplate off and replace the batteries inside. Over time, these batteries can wear down. To avoid this issue in the future, you may want to think about updating your thermostat with a more advanced, self-charging unit that you don’t need to worry about – it will always be on.
- Make sure that your pilot light is on. In some cases, the pilot light inside your furnace may not be lit. If this is the case, you want to light it immediately, because it could be spilling out natural gas into the air. If there are any obstructions, you want to clear the way for the pilot light to get plenty of oxygen. In some cases, you may have to refill the fuel levels, because that may be causing the pilot light to burn out. When it comes to relighting the pilot, all you need is a match or a long lighter.
- Make sure that there are no major obstructions or debris inside the unit. Any foreign object – even if it is as small and seemingly innocuous as a dust bunny – can cause a number of issues inside your furnace. This is why you want to look inside and clear any dirt or debris you see. Make sure, though, that the unit is completely off before you do this.
- Make sure that there are no major electrical issues. Sometimes, the issue can be electrical, which may require the services of a professional HVAC repair company, like Atlas Heating and Air Service. Only qualified HVAC technicians should be solving complicated electrical and mechanical issues. In the end, you don’t want to make the issue worse.
