The cool air in Phoenix may still be a few months away, but worries about your furnace probably aren’t. After all, the last thing you want is for it to fail when you need it the most, and understanding a bit about what can go wrong may help you prevent some of the potential problems involved. This quick overview can help.
Possible Problem #1 – Your Filter is Clogged
In most cases, you should be replacing the filter in your furnace at least once a month and at the beginning and end of every season. In fact, it’s one of the single most important things you can do to extend the life of the furnace and make certain it’s running at peak efficiency. Wondering why? Dirty filters mean poor air flow. In turn, that can cause your furnace to work far harder than it should to make sure warm air reaches every part of your house, and that means one seriously strained piece of machinery.
Possible Problem #2 – Ignition Control Difficulties
There was a time when furnace ignition was a fairly simple process, but there was quite a bit of manual work involved. These days, it’s all automatic, so if your furnace won’t ignite, there’s not much you can do to fix it without the help of an HVAC professional. Most furnaces have one of two possible ignition systems: the intermittent pilot system or hot surface ignition. The latter utilizes a resistance heating element to electronically ignite the burner. The intermittent pilot is electronically controlled too, but it uses an electrical spark to ignite the pilot light, which then ignites the burners, and then it goes off again. Lots of problems can happen with the ignition, and whether it’s an igniter switch or something more complex, a professional is the best person to deal with this problem.
Possible Problem #3 – Thermostat Issues
The thermostat inside the furnace is an essential piece in operations. It decides when to produce heat and just how much is necessary. If it goes, you’re either going to get not enough heat or no heat at all. Like the igniter issue, however, there’s not much you can do to handle this problem on your own. Typically the thermostat itself will need to be replaced, but in some cases, there’s an easier fix. Making that call is best left to a professional, as handling it on your own is not only dangerous, but could invalidate the warranty you have on your unit as well.
Lots of things can go wrong with your furnace, and your best bet to avoid potential problems is to have it checked on a yearly basis before you ever get ready to turn it on. Give your professional HVAC team a call to have yours inspected today.
