It’s wintertime, Crystal Lake! This week in Algonquin and Lake in the Hills, we’re looking at low temperatures close to zero, freezing rain, and highs that don’t break 40! A furnace going out with freezing weather can be miserable. Knowing the most common furnace problems can not only help keep your family warm and cozy — it can prevent costly furnace and HVAC repairs. Here are some of the most prevalent issues facing your home furnace.
When’s the last time you replaced your air intake filter? The changing frequency varies by filter, but here is a good general rule of thumb:
|1-2 Inch Filter||Every Three Months|
|4 Inch Filter||Every Six Months|
|5 Inch Filter||Every Twelve Months|
A dirty filter can cause a slew of furnace problems. Clogged filters can reduce airflow, produce less heat, frequent cycling, and more. Replacing your furnace filter is one of the most basic ingredients in furnace maintenance, but it is perhaps the most important. Take a minute to check your furnace filter to avoid higher heating bills and potential furnace repairs.
Sometimes a heating issue isn’t related to the furnace at all. Think of the thermostat as the brain, telling your HVAC system, the body, what it needs to do. If the brain is broken, the body can’t function properly. It’s the same situation with a faulty thermostat. If your head unit is malfunctioning, your furnace won’t produce the heat you want it to. If you’re experiencing furnace issues that aren’t resolved by a simple filter replacement, try looking at your thermostat. Identifying an issue with your unit may help you avoid an unnecessary and costly furnace replacement.
Rattling and Squeaky Furnaces
Does it sound like the Tin Man is throwing a one-man dance party in your heating and air storage area? Odds are, you’ve got furnace problems. The causes of a noisy furnace range from internal mechanical issues to airflow inhibitions or clogged burners. Try checking your furnace air filter to see if it’s damaged or clogged. If that’s not the issue, it may be time to call a professional HVAC technician. If your furnace is ever rattling or squeaking, don’t wait. Get your unit checked as soon as possible to mitigate the costs of your malfunctioning unit.
Faulty Ignition or Pilot
Not getting any response when you turn your heat on? If it’s not a problem with your thermostat, it could be related to your electric ignition or pilot light. If you have a unit with an electric ignition, this is likely either a wiring issue or a problem with the furnace itself. This will require an expert to diagnose and repair.
An issue with a pilot light is a different story. An unlit pilot light could be caused by simple issues, such as drafts or clogs in the furnace. A clog in the furnace will likely require professional help. However, if you identify there is a draft around your unit that could be extinguishing your pilot light, the fix could be as simple as closing a door or window while your heating system is running.
Wear and Tear
Nothing lasts forever, and your furnace is no exception. General wear and tear is one of the leading causes of HVAC problems. Routine maintenance is imperative to slowing down the rate that your unit degrades. Once per year before the cold season, have an HVAC service specialist inspect your furnace for any potential problems. They’ll make sure your unit is ready to go and reduce the risk of the furnace malfunctioning. These routine checks are a much cheaper investment than furnace repairs or replacements.
