Furnace Tune-Up FAQs: Everything You Need to Know

• A furnace tune-up is preventative maintenance that ensures furnace equipment is in good working condition
• A Reliance^® technician will inspect all major furnace components used to generate and circulate warm air, including the gas valve, igniter, heat exchanger and venter motor.
• In order to ensure safety in the home, the technician measures CO levels both inside the home and in the furnace exhaust using a Combustion Analyzer.

• The technician will call ahead before arriving to confirm your address and the service you’ve booked for that day.
• Whenever possible, the technician will park on the road and keep your driveway free.
• For an AC tune-up, the technician may ask if you have an outdoor hose that can reach the condenser unit on the outside of the home, in case a thorough cleaning is required.
• Entering the home, the technician will keep boots on for safety and wear boot covers to keep your floors clean.
• Entering the mechanical room where you keep your furnace and AC equipment, the technician will quickly flag any hazardous products that should not be beside the furnace.
• The technician will examine the thermostat and proceed with steps to clean, assess and enhance the performance of your unit.
• If there is anything you should be concerned about the technician will explain it in simple, non-technical terms and offer options on what you can do about it.
• After completing the service call, the technician will provide you with a written checklist and assessment of the work done that day.

No. Anyone can clean the surface parts of a furnace or AC unit but only a licensed technician is able to inspect and judge the condition of key functional parts (especially those that have the most wear and tear), optimize gas pressure with a manometer, test CO levels with a combustion analyzer and take apart important compartments for an up-close examination and investigation.

Twelve-point service is primarily about making sure the unit is in good working condition and addressing any safety concerns that may become hazards. A 21-point tune-up is a more extensive investigation and analysis of potential issues that might impact how efficiently the equipment runs.
