Furnace Tune Up Dallas TX

Signs Your Furnace Is Due for a Tune-Up

Some furnaces make it obvious that they need attention. If any of these sound familiar, schedule a visit before the weather turns:

• It Has Been More Than a Year: If nobody has opened the cabinet since last winter, a full season of dust has settled on the burners, flame sensor, and blower.
• Clicking Before It Lights: A furnace that clicks several times, lights briefly, and then shuts off is often struggling with a dirty flame sensor or a weak igniter.
• A Burning Smell That Lingers: A dusty smell during the first hour of the season is normal. An odor that comes back every time the heat runs is not.
• Yellow or Flickering Flames: Burners should hold a steady blue flame. Lazy yellow flames usually mean dirty burners or a combustion problem that needs a professional look.
• Rising Gas Bills: A furnace with dirty burners or restricted airflow runs longer to deliver the same heat, and your winter bills show it.
• Uneven Heat or Weak Airflow: Cold rooms and weak vents often trace back to a clogged filter, a tired blower motor, or duct problems that a tune-up will uncover.

If your furnace has already stopped heating, skip the tune-up and schedule furnace repair instead. And if you ever smell gas, leave your home and call your gas company from outside before you call us.

1. 01

   Burner Cleaning and Inspection

   We remove dust and rust scale from the burners so they light smoothly and hold a clean, steady flame.

2. 02

   Flame Sensor Cleaning

   A dirty flame sensor is one of the most common reasons a furnace lights and then shuts off. We clean it so the control board can confirm the flame every time.

3. 03

   Igniter Testing

   We inspect the igniter for cracks and wear, then cycle the furnace several times to make sure it lights reliably.

4. 04

   Heat Exchanger Inspection

   We inspect the heat exchanger for cracks and corrosion, the one component that keeps combustion gases out of your home's air.

5. 05

   Gas Pressure Check

   We measure gas pressure with a gauge and set it to the manufacturer's specification, which protects the heat exchanger and keeps combustion clean.

6. 06

   Carbon Monoxide and Venting Check

   We test for carbon monoxide at the flue and confirm exhaust gases are venting safely out of your home.

7. 07

   Safety Control Testing

   We confirm the limit switch, rollout switch, and pressure switch each shut the furnace down when they should.

8. 08

   Blower Motor and Capacitor Check

   We test the blower motor and its capacitor, inspect the blower wheel, and confirm strong airflow to your vents.

9. 09

   Filter, Thermostat, and Wiring

   We check or replace your filter, verify the thermostat is calling for heat correctly, and tighten electrical connections.
