What Does an HVAC Technician Do During an Furnace Tune-up?

An annual furnace tune-up may seem like an unnecessary expense. However, when considering the costs associated with a new furnace, high monthly energy bills and unexpected or emergency repairs, the relatively low cost of furnace maintenance becomes much more reasonable.

Make sure the tune-up you are getting is thorough and, at a minimum, consists of these of basic steps:

Visual Inspection

The technician is trained to spot signs of trouble such as cracks, excessive wear and tear, corrosion and leaks, and will also check the air filter and make sure there is proper ventilation. Identifying an issue early can mean the difference between a minor repair or expensive one following a breakdown.

Testing for leaks and fumes.

Equipment that is damaged, broken or poorly vented can create safety hazards including carbon monoxide poisoning. The inspection should include the furnace exhaust outlet in the chimney or direct vent pipe section to check for broken components and cracks and also include the fuel pressure, airflow and the pilot or ignition.

Checking the burners for proper ignition

Safe and efficient operation also requires clean burners with proper ignition. The technician will make sure that the burners are free of dust and debris that can build up over the summer months and that the flame is burning consistently and cleanly.

Cleaning

This should include the outdoor unit, blower, fan blades and drain line which get dusty and dirty over time as well as the indoor components.

Lubricating motor parts

A special lubricant is applied every few years to prevent the motor parts from drying out and becoming damaged.

Replacing the air filter

Starting the season with a new air filter, and then replacing it every 30 to 90 days as needed, is a crucial step in keeping your furnace running smoothly for years.

Testing carbon monoxide detector

Your annual fall maintenance appointment is the perfect time to test the carbon monoxide detector and should be on your technician’s checklist.

Any necessary adjustments

The technician will make any necessary adjustments to return your system to proper specifications for efficient and trouble-free operation throughout the winter.

Written assessment

A written analysis including professional maintenance recommendations for the year should be part of the annual inspection and service.

What you should expect after a furnace tune-up?

The tune-up itself can improve the function and efficiency of your furnace, which translates into fewer repairs, no unexpected breakdowns, lower energy costs and a longer life for your system.
