Annual Furnace Maintenance Checklist

 

Does your furnace frequently break down? Regular maintenance is the key to keep your furnace at peak efficiency and performance throughout the year. When you schedule furnace maintenance, you should know how it is done by your HVAC contractor.

Here’s a checklist of the tasks that your heating professional should perform during maintenance.

  • Inspect essential parts such as the combustion air opening for restrictions or blockages and the gas lines for possible leaks and obstructed pressure.
  • Check the flue pipes for evident signs of leaks and corrosion. The leaks can lead to fire so make sure that the pipes are well-insulated and properly attached. Your technician may recommend replacement of the pipes if necessary.
  • Examine the drive belt for damaged edges and cracks.
  • Also, see if the pilot is in the proper place. Make sure to dust off the pilot and clean the flame sensor if necessary. The dirty or weak pilot can affect the quality and consistency of the flame.
  • Vents should be free from dirt, rust, and debris.
  • Keep an eye for loose or impaired panels to prevent your furnace from sudden breakdown.
  • Maintain a clean drain line. Check the drain lines for obstructions and remove blockages as needed.
  • Look into the combustion blower and check for dirt or debris buildup.
  • Observe anything unusual on the furnace such as strange noises and smell. Abnormal occurrences on the unit indicate issues that linger on the internal or mechanical parts of the system.
  • For old furnaces, two of the most important parts to inspect regularly are the heat exchanger and the burners. Check for deterioration or any cracks on these parts which can become visible as the unit ages.
  • Always clean the fan switch. Also, make sure that it cycles properly by making some adjustments.
  • Check the position of the pulleys and belts. Adjust them if needed to ensure proper flow of air and optimal efficiency of the furnace. Cracked belts have to be replaced.
  • Motors and bearings need to be lubricated as often as possible. Do this to lessen the friction and maintain the unit at peak operating level.
  • Clean or replace the air filters. Replacement might be recommended by your technician depending on the condition of the filters.
  • Examine the voltage and amperage of the compressor, fan motors, and blower motor.

5 Furnace Noises You Shouldn’t Ignore

 

Do you hear a strange noise coming from your furnace? This unit normally produces sound when it is turned on and off, but the rumbling, rattling or clicking sounds are not part of your furnace’s normal operation. Make sure to look into these five (5) furnaces noises that should be addressed immediately.

Clicking

If you hear a clicking noise from the furnace, it explains one thing – a faulty flame sensor. In some instances, the problem might be caused by the vibration of the ducts and other parts of the system. The noise may also indicate an issue in the oil or gas ignition.

Rattling

Does your furnace produce a rattling sound when it turns on? This is an indication of a damaged or worn-out component on the fan or motor of the unit. In other cases, this noise is a sign of carbon monoxide issue. Ask your HVAC contractor to conduct an assessment on every part of your heating system including the heat exchanger.

Booming

Older furnaces commonly produce a booming sound due to gas build-up. When the ignition process is interrupted, most likely, the air ducts are contracting or expanding. Delayed ignition is common on gas furnaces which can lead to a mini-explosion effect if not handled carefully. A delay in the ignition is commonly caused by insufficient gas, impaired pilot light, and dirty or blocked gas burners.

Chirping

If your furnace has not been used for a long time, the unit may start producing a chirping noise. And it is something you do not want to hear in the middle of the cold nights. The strain in the blower wheel possibly causes the high-pitched chirping sound in your furnace. Get this problem fixed as soon as you notice it.

Squealing

The high-pitched and repeated squeal in your furnace is an indication of worn-out belts. If the issues are the belts or bearings, they only need lubrication to function properly. Make sure to provide the belts, bearings and other internal parts the right amount of lubrication to avoid friction.
