In Paradise, living means maintaining a properly functioning furnace, especially during the winter months when reliable heat becomes absolutely essential. When your furnace starts to show signs of trouble, working out what type of repair you need can really help restore that oh-so-welcome glow to your home efficiently and affordably. The errors can range from something as simple as your thermostat being set incorrectly (or the thermostat itself being on the fritz) to problems that might take a little more work to solve, like failures in the ignition system, the blower, or the pilot control. On top of that, a few of you might even experience migraines because of a combustible fuel pressure control valve that severed part of the supply line to your burner. Again, these problems should be in the realm of furnace repair under normal circumstances, and we're short on time to get them done under any circumstances.
When you are experiencing problems with a furnace, it is often difficult to ascertain precisely what the issue may be. You might have an inkling that the problem is mechanical in nature, which could range anywhere from a faulty belt to a seized motor, to something much more serious. On the other hand, maybe your furnace has an electrical or electronic issue, in which case something isn't working that should be, or something is working that really shouldn't be. It's also entirely possible that your problem could be one of those classic "two or more things simultaneously failing" scenarios, which make up a fair number of furnace failures. We'll go into more detail on these classic problem types, plus other reasons why your furnace might stop working, below.
Common furnace repairs are commonly required and easily understood, but their need can still catch homeowners off guard. Furnace problems tend to arise at inopportune moments and in ways that make it difficult to predict when service will be needed. Still, it's good for every homeowner to know what likely repairs their furnace might need, what sorts of symptoms might indicate a repairable furnace, and when to call a heating contractor if it looks like winter could somehow get even colder. Of course, some repairs are more understandable than others. If your furnace ever completely shuts down, and you notice that the furnace itself isn't giving off any heat (which would be a good indication that the heat exchanger is broken), then you might also notice that the pertinent areas of your home are showing no sign of actually warming up at all, which would be good evidence that your furnace is in dire straits.
