If your central heater hasn't been working that well recently, then there are a number of things that might be wrong with it. However, you might not need to go and buy a replacement because you might be able to handle the situation yourself. With a little knowledge and a couple of tools, you will be able to diagnose and fix a wide variety of common furnace problems. To help you get started, here are some solutions to a very common heating problem: a total lack of heat.
No Heat At All?
If your heater doesn't seem to be generating any heat at all, then there is a good chance that it isn't actually getting any power. To determine if this is the case, you want to go out and check the furnace for any heat. If it feels very cold to the touch, or even room temperature, then it probably isn't turning on at all. If there is something amiss with the control panel, then you might be able to tinker with some settings and get your heater back to working condition. In particular, the settings on your furnace might have been adjusted so that it only turns on when a certain temperature threshold has been reached. However, if the settings haven't been adjusted recently, then the solution is probably a little more involved.
Check the Power
You will want to check the actual power source for the furnace. If it uses electricity or is gas-powered and starts via electricity, then you will want to take a look at the power line to the furnace. If it is worn, frayed, or otherwise damaged, then you might need to replace the cord. If there is nothing obviously wrong with the cord, then you will need to go a little further and check the circuit breaker. Power outages can unexpected flip switches in your circuit breaker, as can the act of overdrawing power in part of your home.
Flipping the switch back to its correct position should solve the problem for now, but you will want to figure out why the switch flipped in the first place. If it was an outage, then there isn't much that you can do about it, but if you overdrew power in your garage or wherever the furnace is, then you may need to move some appliances out of that area to reduce the strain on your home's power distribution.
