Maintenance service for your oil furnace

Oil furnaces are an efficient and reliable way to heat your home during the cold winter months. However, like any other heating system, they require regular maintenance to function properly. Without proper maintenance, an oil furnace can become less reliable or even inefficient, resulting in higher energy bills and a shorter lifespan. 

You can count on our comprehensive oil furnace maintenance service to ensure that your oil furnace performs at its best, while remaining safe.

Maintenance tips for your oil furnace


Clean or replace Wash the air filters


It is important to regularly check and clean the air filters on your oil furnace. Dirty filters can cause the furnace to work harder than it should, resulting in decreased efficiency and increased energy bills.

To clean the filter, remove it from the oil furnace and soak it in hot soapy water. Use a soft brush to remove any dirt or debris, rinse the filter and let it air dry. Then reinstall it in the furnace. 

Note that cardboard filters cannot be cleaned, but should be replaced.

Check the oil level


It is also important to check the oil level in the boiler's oil tank to make sure you are not running out of oil. This will prevent the pump from overloading. This should be done regularly, depending on your oil consumption, at least once a year or more often if the boiler is used frequently. 

To check the oil level, locate the tank and check the dipstick. If the oil level is low, add oil to the tank to the recommended level. 

Inspecting the Lines


The fuel line should be checked at least once a year to prevent leaks: our experienced technicians will do this during inspection and maintenance. However, it may be a good idea to check the lines yourself during the year if the boiler is used frequently. Inspect it carefully for cracks or leaks. 

Contact us immediately if you find any or if you are unsure.
