If all else fails…

Let’s begin with this caution—any furnace… that’s any furnace is a place where something burns. How much it burns depends on many things—the temperature outside, the temperature inside, the air movement and leakage of your home. Any furnace may have combustion or gas safety hazards. A malfunctioning furnace is not the place for you to tinker. You need a professional.

You’ve lived in the home for years. The furnace has always worked. All you had to do was to switch on the power and turn up the thermostat. You’ve been aware that some days have been colder than others, but you have attributed that to the wind off the lake and the excessive drops in temperature.

So what’s the problem? Those in the know will tell you that there are these possibilities:

·         The filters are filthy. They told you, when you had the furnace installed, that you had to replace the filters regularly. It’s right there in the manufacturer’s operations manual: replace the filters once a month. Get you down to Lemoi Ace Hardware on Davis Street and buy some filters. You don’t need Mahoney for that, unless you need some instruction as to how to change the filter.

·         The thermostat isn’t “kicking on.” If the furnace doesn’t produce any heat, there is the possibility that the power to the thermostat isn’t functioning. If the thermostat is powered by house power and you don’t have any house power, the problem is bigger than either of us can handle. However, chances are that the thermostat has a battery that needs replacement.

·         The blower fan doesn’t turn on—or off—or there are too many cycles. It’s amazing how many people want to shift the switch away from “Auto.” In the other settings, it just doesn’t turn off.

·         You wouldn’t be the first to move the thermostat switch away from “heat” to “cool.” Or you simply haven’t set the thermostat above room temperature.

We all have those problems—those we can fix ourselves. What about the ones you cannot fix? That’s when you need the skill and experience of a qualified furnace repair Evanston professional. Here’s why:

A routine inspection catches or prevents unexpected problems and breakdowns. It’s the only way your appliances will be set to run efficiently and reliably.

You may have changed the filters; the air now circulates better. Nevertheless, if the filter had become clogged, it’s possible that the fan controls have been “gummed up.”

Furnaces, like people, get old. Normal wear and tear will degrade the heat controls, plug the piping within the furnace unit, and seriously affect the airflow. When something is “stuck,” overheating may occur.

Whether it’s gas or electric, there are ignition considerations. Today’s electronic ignitions are not foolproof. A malfunctioning pilot will mean that the furnace will not light, and that may help to discover problems with thermocouples, drafting airflows, or clogs.

Apart from the problems of the thermostat, mentioned above, there may be fan or comfort difficulties that need adjustment. You should also consider these:

·         Some furnaces simply don’t operate—or don’t operate well. Some reasons have already been mentioned, but what happens if the furnace is the wrong size for the space it must heat? Might it be that the original installation was at the request of the owner who simply couldn’t afford the proper equipment?

·         If the furnace kicks on and off, there are problems of filters, airflow, or settings. If the blower never shuts off, there may be problems with limit switches.

·         Finally, noisy furnaces went out with coal-fired and oil-gun ignitions. If the heating system is banging, wheezing, or sneezing, that’s not normal. It should be checked by a professional.
