Signs Your Furnace Needs Repair Before Winter Gets Worse

Unusual Noises or Vibrations

It’s normal for your furnace to make a soft hum, but loud or unfamiliar noises, such as banging, screeching, or rattling, often mean something is wrong. Loose parts, worn bearings, or motor issues can create noises that signal the need for repair.

If you notice persistent or new sounds, don’t wait. A small fix now can prevent a major failure later.

Uneven Heating Throughout Your Home

If some rooms feel warm while others stay cold, your furnace may be struggling to distribute heat evenly. This could indicate clogged filters, ductwork issues, or a malfunctioning blower motor.

Uneven temperatures not only reduce comfort but also force your furnace to work harder, thereby increasing your energy bills.

A Sudden Increase in Energy Bills

If your energy use hasn’t changed but your heating bills have spiked, your furnace might be losing efficiency. Dirty burners, restricted airflow, or worn-out components can all cause your system to burn more fuel to achieve the same results.

Scheduling a tune-up with H&S can restore efficiency and help you avoid overpaying for heat this winter.

Strange Smells or Yellow Pilot Light

Unusual odors or a yellow, flickering pilot light can indicate incomplete combustion or a gas leak, both of which are serious safety concerns. If you smell gas or notice this type of flame, shut off your furnace immediately and call for professional service.

Our technicians will inspect the system for leaks, ventilation issues, or malfunctioning safety sensors to ensure your furnace is operating safely.

Your Furnace Runs Constantly or Short-Cycles

If your furnace never seems to turn off or switches on and off rapidly, it may be struggling to maintain temperature. This behavior, known as short-cycling, often results from thermostat issues, clogged filters, or inadequate airflow.

Left unchecked, it can cause your system to overheat and wear out faster. A simple inspection can determine whether it’s a minor adjustment or a more serious issue.
