What is Gas Furnace Maintenance?

To prevent emergency repairs and costly replacements, a furnace tune-up is necessary on an annual basis. Gas furnace maintenance ensures that your furnace can work efficiently and at total capacity for many years to come.

A trained and experienced technician must perform your gas furnace maintenance. Any DIY maintenance or tune-ups performed by someone without a certification can result in risks to your furnace, your home, and the person attempting the service.

Signs Your Home Needs a Furnace Tune-Up

If you haven’t had your furnace serviced in over a year or if your furnace is over ten years old, you should consider scheduling a furnace tune-up before you find yourself needing an emergency furnace repair on a chilly night. We also recommend scheduling your tune-up before peak furnace service season to beat the rush, such as in the fall. You may be in urgent need of furnace maintenance if:

  • Your home feels cold even with the heat on.
  • Your furnace is making grinding/scraping sounds.
  • Your furnace constantly turns on and off.
  • Your furnace requires repairs often.
  • Your energy bills have risen.


During furnace maintenance, Assured Comfort goes above and beyond to enhance your furnace’s reliability and durability. Our seasoned technicians inspect your unit’s air filters, condenser coils, drain lines, and more. These inspections can prevent the need for any further repairs and potential health risks.

For instance, dirty air filters can lead to poor air quality within your home, and clogged drain lines can result in mold buildup—two factors that can harm your family’s health. If anyone in your home is prone to asthma, allergies, or other respiratory issues, a furnace tune-up is necessary for everyday life.
