What to Expect During a Furnace Maintenance Service

December 18, 2018


Just like your car, your furnace needs regular maintenance in order to provide you with peak performance at the highest level of efficiency. In general, you should plan to have your furnace inspected and serviced at least once each year. Maintaining that regular schedule can help prevent surprise malfunctions that could leave your St. Louis area home too cold for comfort.

What Happens During a Furnace Maintenance Service

While the exact steps that occur could vary depending on the type of furnace you have, you can expect Scott-Lee Heating Company to perform a thorough inspection that includes the following areas:

Exterior Inspection

The technician will look over the vent system for blockages and/or leakage. During this visit, we’ll. also check the heat exchangers for separations, cracks or other signs of corrosion. The air intake grills will be examined and we’ll clear out any blockages. An examination of the flue will reveal any obstructions that could lead to a build-up of combustion. The presence of this could significantly reduce the quality of the indoor air you breathe.

Interior Inspection

We’ll check and clean the blower motor and its related components. This step also involves removing the blower wheel and removing any debris or dirt that is clinging to it. All moving parts in the motor will be lubricated as needed. This is designed to reduce friction which could make the motor work harder and drive up your costs for heat. The technician will also examine the blower access door to ensure that it has a tight seal.

Testing

We’ll thoroughly test the safety controls that are built into the unit. The high-limit control, which stops the furnace from overheating and becoming a fire hazard, is of particular importance. During the inspection, we also examine all electrical connections to ensure that they are tightly seated. The wiring will be checked to be certain that it is free of corrosion and rust. Finally, we’ll check and test the calibration of the thermostat. When the calibration is correct, your home’s interior is more comfortable and you could save money on your heating bills.
