There is no denying the efficiency of a gas-fueled furnace. The easy-to-operate features of gas furnaces make them a popular choice for countless homeowners throughout our service area. They obviously function a lot differently than their wood-burning counterparts, so many people find themselves wondering what type of professional maintenance they need.

While gas appliances require less maintenance on the part of the homeowner, they still need annual inspections, regular cleanings, and routine repairs from time to time. But what about the liner? There’s no actual flames, so is that extra layer of protection actually necessary? The short answer – yes! Learn more below.

Acidic Gases & Deterioration

man repairing gas furnaceGas-fueled appliances don’t produce fire and smoke, but they do produce acidic gases that can break down your masonry structure. The more your structure deteriorates, the more dangerous your system becomes to operate. Before long, dangerous fumes like carbon monoxide could enter your home, putting you and your loved ones at risk. This colorless, odorless gas can be fatal, and it’s definitely not something you want to take chances with!

Our professionals can reline your flue now before fall weather hits so that you are good to go for the first chilly evening of the season. We also urge our customers to install carbon monoxide detectors throughout their home to ensure they stay safe.


Your gas furnace is also known to produce a lot of condensation, which can break things down significantly if not adequately protected. This encourages mold growth, as well as rotting, rusting, stains, and don’t forget about the harmful freeze/thaw process. All in all, excess moisture is definitely something you want to avoid, and a well-fitted, properly installed liner is one surefire way to achieve that.

Draft & Efficiency

When it comes down to it, you need your furnace functioning as efficiently as possible to ensure you get the warmth and comfort you need this winter. Liners can help direct gases up and out of your flue, so your system works better and faces less decay and deterioration. You deserve to get the most from your appliance!
