Understanding Furnace Maintenance
Professional furnace maintenance extends well beyond changing an air filter and making sure the system runs. Rather, it’s a multi-step approach to improve system efficiency, inspect the unit, and test system performance.
The first step is deep cleaning the system, which usually includes the heat exchanger, circulating fan, and burner compartment. This ensures that air can flow freely through the system and that safety controls aren’t triggered.
Next is an inspection of the unit, which includes looking for external signs of corrosion and damage. However, it also includes a deeper inspection of the heat exchanger to ensure it’s not cracked. A technician will also inspect the mounting hardware within the furnace unit and its electrical wiring. They’ll tighten any loose connections and hardware to prevent unusual wear or strain.
Your technician will also complete a series of important tests as part of your furnace maintenance.
- Ignitor function
- Heating cycle progression
- Temperature rise at supply vents
- Carbon monoxide and gas leak checks
- Thermostat accuracy and function
- And more!
While repairs aren’t included in the standard furnace tune-up, it will help identify small problems early on. This is critical in protecting your unit’s service life by reducing the strain added to the entire system. You can then address these problems as a planned service rather than an emergency during Agra’s coldest months. The sooner these are addressed, the better!
