The Importance Of Regular Heating Oil Filter Replacements

This article explores oil filter replacements and how it impacts your system’s costs, performance, and service life.

What is a Heating Oil Filter?

Home heating systems that utilize fuel oil all have heating oil filters. The fuel passes through this cartridge to eliminate impurities before entering the burner. The filter keeps dirt and moisture from blocking the fuel nozzle. It also helps ensure that the pump works as it should. The heating system needs to have an operational filter so that equipment damage and system lockouts are prevented.

Filters trap dirt. Consequently, their surfaces get less porous as time passes. This means that the oil’s flow rate drops until it stops. Some dirt may even get into the system and clog it. Change the oil filter before this occurs. Keep in mind that a new oil filter will eventually get clogged with debris, so it is crucial to repeat the process as often as necessary. Make this part of your regular heating system maintenance checklist. Fortunately, replacing filters is a quick and easy process. It also comes with several rewards.

All heating units have a yellow sticker on it, otherwise known as EnergyGuide label. This label contains your system’s efficiency rating on it. Unfortunately, all heating system lose their efficiency as time passes. Components wear out, and dirt accumulates as time passes, decreasing efficiency gradually.

Inefficiency results in more fuel consumption, which isn’t good for the environment that’s already suffering from high carbon emissions. Book annual professional heating tune-ups for your system to keep efficiency high. HVAC technicians can conduct a thorough checkup during this visit. Remember to change the oil filter per the manufacturer’s suggested schedule. These tasks help ensure your HVAC system remains in tip-top shape.

How Often You Should Change the Heating Oil Filter

Replacing the heating oil filter at least once a year is recommended. Change it before the start of the heating system so you are sure of smooth oil filtering. Check the system performance throughout the cold season and watch out for any decrease. You should increase the frequency to twice yearly if you experience filter clogs. Replace it halfway through the season so it doesn’t happen again.

How to Tell When Your Oil Filter Needs a Replacement

Here are several signs that point to an oil filter needing a replacement:

  • Slow Starts: You know how your furnace or boiler behaves if you’ve used them for some time. Watch out for unusual behaviors like slow starts and odd sounds. The system may be experiencing difficulties due to a clogged filter.
  • Dark Smoke: It isn’t unusual for a system to emit light-colored smoke. However, it is concerning if dark smoke rises from the chimney. This issue means that water is passing through the oil filter. When did you last replace the oil filter? As time passes, the old filter may be clogged with debris and moisture. You should replace it immediately.
  • Subpar Performance: Do you feel cold in your home? Do any changes occur when you increase the thermostat settings? If your heating system isn’t providing sufficient warmth, the oil filter may be dirty. The same is true if your system turns off suddenly. The clog may be on the filter or a nearby part.
