Furnace Tuneup 411—Here’s What to Expect From Routine Maintenance

HVAC repair technician servicing a furnace

Your furnace will run practically nonstop when winter hits. Because you use it so much, it goes through a lot of wear and tear. That’s why the experts at S&R Heating & Cooling recommend getting an annual furnace tuneup. It comes loaded with benefits, including:

  • Increasing your furnace’s lifespan
  • Cutting down the likelihood of future breakdowns
  • Boosting your unit’s energy-efficiency
  • Saving you money on energy costs

But what actually goes into furnace maintenance? What can you expect from the job?


The first step of our furnace tuneup service is visual. On the outside of your furnace, we ensure there’s no black soot or combustion residue. On the inside, we inspect several facets, including ensuring the burner flame is steady blue (not yellow or orange), checking the water condenser for corrosion, and confirming gas valve and limit safety.

Additionally, parts will be examined for blockages and proper connections, including:

  • Vent systems
  • Air intake grills
  • Blowers and blower wheels
  • Tight electrical connections

Thorough Cleaning and Testing

With time and frequent usage, your furnace will collect dirt and dust, which can cause it to stop working if left unchecked. Part of a furnace tuneup includes checking the unit, blower, fan blades, drain line, and evaporator coil and cleaning them when necessary. Our experts will also drain and clean traps and tubing, as well as clean burners and sensors to ensure the system operates as efficiently as possible.

Once everything is clean, we’ll test it out to ensure it works and prevents potential leaks and harmful fumes from circulating through your home. That includes checks for:

  • Carbon monoxide
  • Proper fuel pressure
  • Airflow
  • Thermostat controls

Filter Replacement

Keep your indoor air clean, healthy, and moving properly by cleaning or replacing your air filter regularly—change standard one-inch filters once every one to three months, or once every six to 12 months for high-efficiency filters.
