DIY Fixes vs. Professional Gas Fireplace Repairs

Before we get into specific issues, let’s address the DIY vs. professional gas fireplace repair question. While some gas fireplace problems can be resolved by homeowners with a bit of know-how, others require the expertise of a trained technician. 


Here’s a general rule of thumb:

  • DIY Fixes – If the issue seems minor, like remote control batteries or being out of fuel, you can attempt to fix it yourself. However, if you’re unsure or uncomfortable, it’s always safer to call in a professional.
  • Professional Gas Fireplace Repairs – For more complex issues, such as problems with the gas valve, ignition system, or safety sensors, it’s best to let a trained technician handle the repairs to ensure safety and effectiveness.


Again, if there’s any hesitation or question, feel free to chat with our Dick’s HVAC specialists. We’re here to help! 

Common Gas Fireplace Problems

Below you’ll find an alphabetical list of some common gas fireplace problems.


Burning smells – If you notice a burning smell, it could be due to accumulated dust or debris on the burners or logs. Try cleaning them as recommended by the manufacturer.


Clogged air inlet or exhaust – Debris or foreign objects in the air inlet or exhaust can affect combustion and ventilation. Check for obstructions and clear them if necessary.


Clogged vent or chimney – A blocked vent or chimney can restrict airflow and lead to poor combustion and venting issues. Ensure proper ventilation by clearing any obstructions.


Condensation – In high humidity conditions, condensation can form on the inside of the glass, obstructing the view of the fire. Reduce humidity in the room or use a dehumidifier to prevent condensation.


Delay in ignition – If you experience a noticeable delay between turning on the fireplace and the flames appearing, inspect and clean the ignition system. If delays continue, professional help is recommended.


Excessive noise – Unusual noises, such as whistling or hissing, can indicate issues with the gas flow or venting system. Check for obstructions and ensure proper venting. If noise persists, seek professional assistance.


Fire goes out and comes back – This issue could be due to drafting problems or gas pressure fluctuations. Ensure your vent is clear of obstructions and call a technician to assess gas pressure.


Fireplace wall switch – If your wall switch malfunctions, inspect it for loose connections or damage. If needed, replace the switch.


Freque‌nt & heavy soot buildup – Accumulated dust, debris, or soot on the burners or logs can affect the appearance of the fire and its efficiency. Clean the burners and logs as recommended by the manufacturer.


Gas smells – If you detect a gas smell, never attempt to fix it yourself! Turn off the gas supply and call a professional immediately.


Out of fuel – If your gas fireplace suddenly stops working, you might be out of propane or natural gas. Check your propane tank or gas supply and replace it if needed.


Pilot light is out – If the pilot light goes out, follow your manufacturer’s instructions to relight it safely.


Pilot light won’t stay on – If the pilot light keeps going out, it could be due to issues with the thermocouple or thermopile. If you’re comfortable, try cleaning or adjusting these components. If the issue persists, it’s time to call a technician.


Remote batteries dead – If your remote control isn’t working, you may need to replace the batteries.


Remote control interference – Interference from other electronic devices can disrupt the communication between the remote control and the fireplace. Keep other devices away from the remote control to minimize interference.


Thermostat problems – If your gas fireplace is connected to a thermostat, issues with the thermostat’s wiring or settings can impact its operation. Consult a technician to address thermostat-related issues.


Unbalanced fire – If you notice an unbalanced flame, it could be due to gas pressure problems. Contact a technician to assess and adjust gas pressure.


Visible rust – If you see rust on your fireplace, remove surface rust with a wire brush and apply high-temperature paint to prevent further rusting.

Dick’s Air Conditioning & Heating, LLC just left our house after servicing our furnace and heat pump. I have never had such a wonderful experience with a maintenance person. They were polite, friendly and very professional. They explained everything extremely clearly. Would highly highly recommend them.

Bill Williams

The service by all the three men was excellent they were professional on time and thorough. I especially like the way the last workmen to leave the house (Trey Brown) went to the house to ensure no debris or trash had been left. I see why my father’s been using you all for at least the last 30 years thank you. Thank you all for such GREAT SERVICE!

Judith Nelson

Sandra Wynne

Dick’s really came through for us! Patrick came out on very short notice to diagnose our dead a/c – his experience and knowledge cannot be beat. Linda and Tommy scrambled to find us a special part STAT so that we could be up and running as soon as possible. They are the best!

Callie Russell

Thank you for your service in piping in the natural gas for the new free standing natural gas fireplace. Your crew did an outstanding job from estimating to the final installation. The inspector was here today for the final inspection and all went well.

Larry Peed

I called and they were very professional. Lisa helped me figure out what I could do while I waited for my AC unit to be serviced and it helped a lot. She then called and sent me a text that they could schedule me for an earlier day than originally available. When Josh came, he was very kind and knew exactly what to do. He also answered all our questions. Our AC unit is up and running. If ever we need the AC serviced, we will definitely use them again!
