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.
