Picture this, you are covered up to your neck in blankets on a cold winter's night watching movies. You have your popcorn or candy half eaten already, but then you realize you're a little chilly still. You move to the thermostat and press the button up a few degrees, you've done this hundreds of times so you don't even think twice about it. You go back to your seat, but the heat never turns on. You try the thermostat tactic again, but once more there is no noise coming from your heaters. Quickly you realize something is wrong, potential dangers start to run in your head - will I freeze, will the pipes freeze, what if the electronics are damaged? Who do you call? You begin thinking of all the HVAC contractors out there with the most experience, then it dawns on you - that's LIBERTY AIR! With 24/7 heating and cooling services, we can help you!
But we will get into that later, for now, let's focus on some of the reasons your furnace might be broken.
Check Your Thermostat!
The first step to do is to check the thermostat and make sure it is set to "heating" and that it's also set high enough to warrant kicking the system on. Most Texans will turn their thermostat to "fan" during the summer, but you will want to change that to heating in the winter. This is actually the most forgotten step in the winter, but it's the easiest fix!
Do you have power?
Whether or not you have an electric or gas furnace, it still needs power to operate. If it won't start check for a blown circuit breaker and make sure that any wires surrounding the system haven't been chewed through by rodents or that they have become corroded.
Is your pilot light working?
Give your furnace a quick check to make sure the blue pilot light is lit. Having them go out is quite a common occurrence that we have seen. The most common way to turn that back on is with a strike of a match.
Do you have a large enough gas supply?
The last DIY action to try is to make sure that the gas valve is fully turned on so that the furnace has an enough supply to fire up the system. Often times homeowners believe that it is a good idea to only partially turn the valve for safety reasons. However, the valve should either be completely turned on or completely turned off, this is the main reason why many furnace manufacturers have switched the valve to an off & off switch or a button.
