In short, yes, gas fireplaces create fewer pollutants and are considered more environmentally friendly than traditional ones. In general, natural gas fireplaces release only half to two-thirds as much CO2 per unit of heat (BTU) as burning wood. Plus, gas fireplaces emit fewer harmful particles and air pollutants. They can also be about three times as efficient as wood in terms of heating your home, resulting in a much higher level of their energy converting into heat.

Once your ashes have fully cooled, you can place them in a heavy-duty trash bag and put them into the bin with your normal trash. If you have wood ash, you can add the ash to your composting pile or sprinkle it over your grass or plants directly for added nutrients.

Certain fireplace repairs will require that your contractor is licensed, including anything that involves moving, installing, or repairing gas lines. In that case, your professional will need to be a certified plumber. You can use Angi’s licensing lookup tool to confirm that the company you’re hiring is properly licensed. Most states don’t have specific license requirements for other fireplace repairs, but most demand at least a general contractor’s license. It’s also a good idea to look for companies certified by the National Fireplace Institute, as those pros tend to be more qualified to carry out the repair.

Pellet stoves are much more energy efficient than traditional fireplaces, and the pellets they burn create fewer emissions, leaving indoor and outdoor air cleaner. Plus, the biomass pellets are made from recycled materials, making them even more eco-friendly. You can also adjust the temperature of a pellet stove and go about most of your day without needing to tend to it.
