What Are Signs You Need Heating Repair?

Now that it’s getting cold, you need a furnace to keep your home comfortable and liveable. If your system has not been previously maintained, it is probably showing signs of wear and tear. As the owner, it is important that you be aware of the warning signs of a failing heating system.

Signs that your heating unit needs repair

If you notice any of the signs below, schedule a repair immediately when needed.

  • High Electricity Bill

Dramatically higher electricity bills signify that your furnace is drawing more energy and not running efficiently. These sudden spikes are caused by your overworking heating system, which needs immediate attention.

  • Noises from the Furnace

Loud sounds from the furnace are not normal. You should pay attention when any banging, screeching, squeaking, rattling, or hissing sound comes from your system. These noises are a prior signal that an internal component of your furnace has broken down and needs repair. Do not try to inspect and repair the device yourself; let a professional handle the job.

  • Poor Air Quality

If you notice your family members frequently coughing or sneezing, know that the indoor air quality of your home is below average. For as long as your furnace malfunctions, it releases contaminants, allergens, and dust particles into the indoor air that can lead to respiratory issues like asthma and allergies. Clean and change your furnace air filters regularly to prevent the circulation of pathogens and dust. The hazy atmosphere of your home also indicates you need proper vacuum cleaning before calling for professional help.

  • Hot and Cold Spots

When a particular room in your house is warm while the others are cool, or if the warm air is not reaching all the places evenly, your furnace ductwork might have some problems. Airflow issues in older homes with old duct fittings are common and disturbing. Call us for heating repair in Olney, MD, to fix the issues immediately.

  • Yellow Pilot Light

A non-malfunctioning furnace shows a blue pilot light. This blue light indicates that no residues are left after combustion, so your furnace is at peak efficiency. But, if the light changes to yellow, orange, green, red, or any other color, you have a serious disaster. Due to incomplete combustion, pollutants like rust or smoke are produced and released into your home’s air.

  • Foul Smell from the Furnace

A properly working furnace produces no smell, good or bad. So, if you notice a distinct smell of burning, fuel, or dampness, your furnace needs inspection. Musty odors indicate the growth of mold and mildew due to excess moisture in your ducts. Schedule a thorough inspection to avoid huge problems.

  • Frequent Thermostat Adjustments

When you need to adjust the thermostat settings frequently and still cannot get the right temperature, your furnace has serious issues. The thermostat is the key device that regulates the temperatures in your furnace. If there is no efficient heat after several modifications, it wastes electricity until you get a professional inspection and repair.
