Frequently Asked Questions About Gas Fireplace Services
How often should my gas fireplace be serviced?
Gas fireplaces should be professionally serviced once a year to ensure safe operation, clean burners, check for gas leaks, and inspect components for wear.
Why won’t my gas fireplace ignite?
Common reasons include a dead battery in the remote, a faulty thermopile or thermocouple, or an issue with the gas supply. A technician can quickly diagnose and fix the problem.
Is it safe to leave a gas fireplace on overnight?
It’s not recommended. Even though gas fireplaces are safer than wood-burning options, it’s best to turn them off when unattended to reduce risk and wear on the system.
