Just because your furnace is running doesn't mean it's in good repair and will continue to work for months or years to come. There are some signs that your furnace may need the attention of a professional even if it seems to be operational, and ignoring these signs can allow it to break down even further and cause more damage. Consider some signs that your furnace or even your central air conditioning unit should be checked by a repairperson.
1. You hear any type of banging, grinding, or other odd noise
A furnace and a central air conditioning unit may make a low hum as the motor and fan both work to push air through, but any type of banging, grinding, or other odd noise should be checked out immediately. A banging may mean that a part has come loose or broken off completely and a grinding noise may mean something is caught in the unit itself. Ignoring these noises can allow more damage to occur and in turn you may need more extensive repairs down the road.
2. Your utility bills suddenly spike
Unless you've gotten a rate hike from your utility company or can otherwise explain a sudden spike in your utility bills, you may want to consider that a sudden increase in the cost to run your furnace or your central air conditioner means that either one needs repair work. Typically if they need to work harder to push air through your vents because of a part breaking down, then you'll see a spike in your utility bills. If you notice a sudden increase one season and especially from one month to another, consider having a repairperson check your heating and cooling systems.
3. Your home is not being heated evenly
Unless you have a zone thermostat that allows you to adjust the temperature in different areas throughout your house, your temperature should remain relatively constant from room to room. However if you notice that one room is very cold while the other rooms are the temperature set by your thermostat, this may be a sign that your furnace is breaking down. It may not be blowing warm air as it should through all your vents, typically because the motor or fan or other major part is malfunctioning. Have a repairperson inspect it as this problem will typically just become worse over time.
Remember these three signs that your furnace and even your air conditioner may need repair and if you notice any of these signs, call a professional like Comfort Solutions to inspect your unit as soon as possible.
