When to Call for Heater Repair

Winter weather demands a fully functional heating system for safety and comfort. While it's easy to overlook the furnace or boiler when it's operating smoothly, failing to heed warning signs of a struggling system can lead to a more costly heater repair or even the need for an early heater replacement. This post discusses some common signs that indicate the heater needs repair.

High Utility Bills

bills One common sign of a heating system issue is unusually high heating costs. High utility bills are often caused by heating system inefficiency, which can result from factors such as a malfunctioning thermostat, a clogged or dirty air filter, neglected heating maintenance, an air duct leak, problems with the blower motor or fan, and more. 

Ignoring this sign means continuing to pay excessive energy bills while putting unnecessary strain on the system. Keep in mind that aging equipment or neglected maintenance can also contribute to high heating costs, but if the unit has been well-maintained, has regular furnace filter replacement, and isn’t old and nearing the end of its lifespan, it's a sign of an issue that needs repair. Professional heating repair allows a technician to pinpoint and address the cause of the inefficiency, restoring the unit's performance and bringing utility expenses back down. 

Strange Noises or Smells

Loud or unusual sounds often signal mechanical issues or component failures that require repair. Be alert for strange sounds, such as grinding or scraping, squealing, banging, rattling, and more, as these are signs of problems that require professional attention and repair. Allowing these issues to persist increases the likelihood of additional damage or system failure, potentially turning a simple repair into a more costly and severe problem.

While a brief burning smell when the heater kicks on for the first time of the season is normal due to dust accumulation, any ongoing burning smell is a safety concern. If a burning odor persists beyond the initial start-up, it could indicate electrical wiring issues or overheating, which pose a potential fire hazard. A sulfur or rotten-egg smell is an urgent sign of a natural gas leak. So, if it’s noticed, immediately turn off the unit, evacuate the premises, and call the gas provider and a professional for repair from a safe location.

Insufficient Heating

coldThe primary job of the heater is to keep the home warm and comfortable. If it fails at this task, it indicates heating repair is necessary. Signs of diminished heating performance include:

  • No Heating: When the heater won’t turn on or doesn’t provide any heat, it’s the most obvious sign of a problem.
  • Failure to Reach the Thermostat Setting: If the system runs but cannot reach the temperature set on the thermostat, it also indicates the need for repair.
  • Cold Spots or Uneven Heating: Significant temperature variations between rooms, creating cold spots or uneven heating, also indicate issues.

Trying to solve insufficient heating by simply cranking up the thermostat is counterproductive. It forces the unit to work harder, accelerates wear and tear, and drives up utility bills. A professional inspection is essential to determine the cause, which could range from a malfunctioning thermostat to an issue with the heat exchanger. Repairing the underlying issue will restore reliable, consistent warmth and comfort to the home.
