Oil Heating System Installation and Maintenance from the Experts at First Call Heating and Cooling


As the temperature outside gets cooler, your furnace is put to the test. A well-maintained furnace can keep your home warm and comfortable throughout the cold season. Conversely, a poorly maintained oil heating system compromises the heating capabilities of your furnace. With expert installation and a program of routine annual maintenance, your home’s heating system can operate at its best.

Oil System Maintenance Services by First Call Heating and Cooling

There have been numerous changes in the heating industry to ensure maximum safety of oil furnaces. As a result of these advances, your aboveground or underground tank must now meet certain specifications. Our technicians can inspect your tank and help bring it up to current safety codes. This might include covering your tank in a composite material to provide a secondary fire barrier. Also, we will inspect your tank for leaks, rusting, or malfunctioning parts. Aboveground tanks, especially older models, are prone to corrosion. Therefore, it is important to have your tank properly maintained and inspected.

Our furnace maintenance and tune up service includes:

oil furnace tuneup

  • Visual inspection of the entire system.
  • Vacuuming all heating elements, and removing dust or debris.
  • Checking flues to make sure they are clear.
  • Replacing filters.
  • Cleaning all parts.
  • Sealing leaks.
  • Using a combustion test to measure efficiency.
  • Starting and stopping the furnace to test for operational efficiency.

Benefits of a Properly Maintained Oil Heating System
