As summer winds down and cooler weather starts to creep in, it’s the perfect time to give your home’s heating system some attention. Many homeowners don’t think about their furnace until it’s absolutely necessary—but by then, small issues could have turned into big problems.
At Michael Runk Plumbing & Heating, we help Maryland homeowners prepare their systems before the cold sets in. If you want to avoid unexpected breakdowns and costly emergency repairs, keep an eye out for these common warning signs that your furnace might need attention.
Unusual Noises During Operation
It’s normal for your furnace to make a soft hum when it’s running, but if you hear banging, rattling, whistling, or squealing noises, something could be wrong. These sounds might indicate loose components, a worn-out belt, ignition problems, or even airflow issues. Catching these problems early can prevent more serious (and expensive) damage.
Uneven Heating Throughout Your Home
If certain rooms in your home are noticeably colder than others, your furnace could be struggling to distribute heat evenly. This might be due to a clogged filter, malfunctioning blower motor, or issues with your ductwork. A professional tune-up can restore comfort and ensure efficient heating throughout your entire house.
Unusually High Energy Bills
A sudden spike in your heating bill, even when usage hasn’t changed, is often a sign that your furnace is working harder than it should. Whether it’s a dirty filter, aging parts, or a thermostat issue, inefficiency costs you money every month. Regular maintenance can help your system run at peak performance and save you from overpaying on utilities.
Short Cycling or Constant Running
If your furnace turns on and off frequently (short cycling), or runs constantly without reaching your desired temperature, there may be an underlying issue. These behaviors could be linked to a faulty thermostat, poor airflow, or a malfunctioning sensor—all of which require professional diagnosis and repair.
A Yellow or Flickering Pilot Light
If your furnace uses a pilot light and it’s yellow instead of blue, or flickers often, it could be a sign of a ventilation issue or carbon monoxide risk. This is a serious safety concern that should be addressed immediately. At Michael Runk, we inspect and service furnaces to ensure they run safely and properly.
