Gas Fireplace Won’t Light or Stay Lit?

A gas fireplace that won’t light or stay lit usually has a worn thermocouple or thermopile, a weak pilot flame, a faulty igniter, a failing gas valve or a venting problem. Check the batteries and the wall switch first. Leave gas controls to a trained technician, and call AVS if the problem continues.

Homeowners who want to check the basics first can follow our gas fireplace troubleshooting tips before booking a visit. AVS technicians have access to manufacturer parts for all makes and models, so a worn part can be replaced rather than guessed at.

Smell Gas Near Your Fireplace? Do This First

If you smell gas near your fireplace, shut off the gas only if it is safe to do so, avoid flames and light switches, and leave the home. Call your gas utility or 911 from outside.

Should a carbon monoxide alarm go off, step outside with your family and call 911 before doing anything else. Contact AVS afterwards to book an inspection.

Gas Fireplace Inspection, Cleaning and Maintenance

A gas fireplace looks simple, but the burner, the gas connections and the vent all have to work together safely. A maintenance visit from AVS is built around that. Most homes need one visit once or twice a year, and each visit includes testing the gas lines and electrical connections, cleaning the components and running safety checks.

Why a yearly inspection matters Every gas fireplace should have a safety inspection once a year because of venting, even one you rarely use.

Before winter If your family uses the fireplace often, book a service before the cold season starts.

Cleaning at home versus by a technician Wiping the glass and dusting around the unit is easy for homeowners, and our gas fireplace cleaning guide explains how. Gas components, burner parts and clogged vents are better left to a technician.

Fireplace Services We Offer

AVS handles repair, maintenance and installation for the fireplaces found in most homes. Here is what you can book.

Gas fireplace repair Diagnosis of the fault and replacement of worn parts, from a pilot that won’t stay lit to controls that have stopped responding.

Service, tune-up and cleaning Seasonal maintenance for your gas fireplace, priced as shown in the inspection table above.

Gas fireplace inspection A yearly safety inspection of the unit, its connections and its venting.

Gas fireplace installation and replacement A new unit where you have none, or a replacement for an old one.

Gas fireplace inserts An insert fits into an existing masonry fireplace and turns it into a gas heating unit.

Electric fireplace installation A choice for rooms where venting isn’t practical, since an electric unit needs no vent.

Outdoor gas fireplace installation Outdoor gas fireplaces installed and connected by our team.

Wood-burning fireplaces and pellet stoves We service these as well. A wood-burning chimney with creosote buildup should be cleaned by a certified chimney sweep.

Adding or Replacing a Gas Fireplace or Insert

Three choices shape a new gas fireplace: where it goes, how it vents and which fuel it burns. We talk through each one with you during an in-home assessment.

Insert or built-in A built-in unit can go where no fireplace exists today. An insert is the alternative when you already have a masonry fireplace.

Venting Direct-vent units exit through a wall or roof and suit most homes. Vent-free units come with strict room-size and code limits, so we confirm what your home allows before you choose. Our guide to how a gas fireplace is installed explains the venting types, permits and costs in detail.

Fuel Choose natural gas if a gas line already serves your home, or propane if it does not.

Financing A new fireplace or insert can be financed. Start with the financing application for a quick credit decision.

Frequently Asked Questions

How much does a gas fireplace repair cost?

According to HomeAdvisor, gas fireplace repairs typically run from $200 to $1,000, depending on which part has failed. At AVS, a home visit gets you a prompt quote for your own fireplace.

Who should I call to repair a gas fireplace?

Call a licensed, insured and trained technician who works on gas fireplaces. Repairs involve gas lines, pilot assemblies, igniters and venting, and gas-flow controls are not a homeowner job. AVS repairs gas fireplaces across Northern Virginia and Maryland, and our 24/7 emergency service is there if the problem can’t wait.

Do gas fireplaces use a lot of gas?

Not usually. A standard 20,000 BTU gas fireplace uses about 20 cubic feet of natural gas per hour, and it is typically cheaper to run than electric heat.

How much does gas fireplace installation cost?

According to the figures in our installation guide, labor runs about $600 to $1,600, a gas fireplace insert starts at about $1,200 and a custom installation can top $4,000. The total rises with a new gas line, roof venting, chimney relining, electrical work or a custom surround.

How long does it take to install a gas fireplace?

The fireplace itself can often be set in about a day, but the full project usually takes several days once framing, gas, electrical work and the final inspection are included.

Do I need a permit to install a gas fireplace in Fairfax County?

Yes. Fairfax County requires a permit even for a like-for-like replacement, under its Household Appliance (HAPL) permit, which includes one inspection. New gas piping needs a residential plumbing permit instead. Arlington, Loudoun, Prince William and Maryland jurisdictions set their own rules, so check the requirements for your address before work starts.
