At Americool Heating & Air Conditioning, we know that your gas fireplace provides both warmth and comfort, especially on cold days. If you’ve noticed that the flame flickers a lot, it may be time to take a closer look at the fireplace. Flickering flames can point to issues with your system, and some of these problems can get worse over time.
For homeowners with gas fireplaces in Grandview, WA, here are five common reasons why your flame might flicker and what you can do about it.
1. Low or Inconsistent Gas Pressure
Low or fluctuating gas pressure is a top cause of flickering flames. The gas pressure in your fireplace must stay steady for the flame to burn consistently. But sometimes, issues in the gas line, like blockages or small leaks, can reduce pressure. In other cases, the source may have supply issues. Either way, inconsistent gas pressure is something only professionals should handle. Our trusted HVAC technicians can check for leaks, clear any buildup, and restore proper gas flow.
2. Dirty or Clogged Burner Ports
Over time, dust and dirt will build up in your fireplace. When that happens, the burner ports can clog, causing an uneven or weak flame. A dirty burner makes it harder for your fireplace to keep a steady flame. That’s why affordable HVAC maintenance is a smart idea. Regular cleaning keeps your system running right and helps prevent flickering issues. We recommend scheduling a maintenance check to clean and inspect your gas fireplace, making it easier to enjoy steady, safe heat at home.
3. Poor Ventilation or Blocked Airflow
A lack of airflow affects your fireplace’s performance. Poor ventilation or blocked vents can make the flame unsteady, and these issues can also affect your home’s indoor air quality. An experienced technician can inspect the vents for any blockages or obstructions. If there’s a problem, they’ll clear the vents to improve airflow. With our indoor air quality solutions, you’ll have peace of mind knowing your home’s air is fresh and safe.
4. Drafts or Air Leaks Near the Fireplace
Drafts around the fireplace can cause the flame to flicker. Common sources of drafts include nearby doors or windows and small gaps in the fireplace structure. Even minor drafts can affect flame stability. During an inspection, our HVAC repair service team can find and fix any drafts or gaps. After identifying the cause of the draft, we can repair these gaps to help keep your flame stable.
5. Faulty Thermocouple
The thermocouple in your gas fireplace monitors temperature and adjusts the flame as needed. When this component malfunctions, it can cause your flame to flicker or go out entirely. Thermocouples wear out over time and need replacement. If you think your thermocouple is the issue, give us a call. We have NATE-certified HVAC experts who specialize in handling these and other gas fireplace issues. With our 24/7 emergency HVAC support, you can count on us to restore your fireplace’s performance any time.
