When To Have A Furnace Repaired?
It is not uncommon for a furnace to malfunction. But unlike other appliances, a furnace does not go out of service abruptly. Instead, it gives out clues or signs associated with glitches.

A furnace helps in keeping a home warm and cosy during the chilly days of winter. However, this appliance is a bit different from the others and may not go out of service all of a sudden due to some major problem. Rather, it starts to show signs that indicate a necessity for repair service. If you are not aware of those signs, here are they given below:
Steeply Rising Bill
Has your electric bill been making you hyperventilate every winter? If yes, then it can mean that your furnace is not serving you as it should and has either gotten old or requires proper maintenance. The appliance is taking longer than it should to exude the necessary heat for warming up your home.
Yellow Pilot Light
A burning yellow pilot light on the furnace is an obvious indicator of the fact that the combination of gases within the appliance is not appropriate. And that unsuitable combination is leading to creation of carbon monoxide and diminishing of the usual blue flame. If blue flame is entirely absent (sign of good gas combination), you must get in touch with a good repairer immediately.
Frequent Thermostat Adjustments
Do you have to adjust your thermostat nearly a dozen times every day when it is freezing outside? Maybe one room is getting excess heat and the other seems to be competing with your refrigerator. Such problems can possibly be triggered by a faulty furnace incapable of distributing heat uniformly.
Strange Noises
Of course, your furnace cannot be expected to maintain pin-drop silence. But it also should not be making strange squealing, whining, popping or banging noises. These kind of noises usually indicate ignition issue, component glitch, a loose belt, etc. You must call in a suitable repair service provider to have the appliance fixed as soon as possible.
Poor IAQ
Were you aware of the fact that a malfunctioning furnace can also hamper the indoor air quality? When residential heating fails to do its job, illnesses like asthma, flu, allergies, etc. become more common among the family members. Now you know what might be responsible for your kids missing school in winter.
Condensation On Windows
Although this is not as serious a sign as the others mentioned above, condensation on windows even in the presence of a furnace can be an indicator that you need to contact a professional.
These are the signs you need to watch out for if you think the furnace within your house is not working like it’s supposed to.
