Why Appliance Chimney Inspections Are Critical

Gas and oil-burning appliances need properly functioning venting systems to remove dangerous byproducts like carbon monoxide and sulfur dioxide. A neglected chimney used by a furnace or water heater may become clogged with debris, corrosion, or condensation damage—leading to:

  • Carbon monoxide exposure – odorless, colorless, and potentially fatal.

  • Reduced appliance efficiency – increasing your energy bills.

  • Moisture intrusion – leading to rust, mold, and masonry deterioration.

  • Complete system shutdown – if blocked flues trigger safety mechanisms.

If your appliance vents into a masonry chimney, an annual inspection is not just a smart move—it’s a critical safety measure.

Comprehensive Gas & Oil Appliance Chimney Inspection Services

Gas & Oil Appliance Flue Inspections

We provide Level 1 and 2 inspections for chimneys, venting furnaces, boilers, and water heaters. Our process includes:

  • Visual inspection of the flue structure and liner

  • Testing for proper draft and airflow

  • Identifying blockages or corrosion

  • Checking for deterioration from moisture or acidic combustion gases

Even if your appliance is high-efficiency or power-vented, it may still rely on the chimney as part of its venting route. Our certified inspectors assess compatibility and safe operation.

Chimney Liner Condition Assessment

Many older homes in Westchester have unlined or clay-lined chimneys, which are unsuitable for modern appliances. We inspect for:

  • Flue liner cracks or missing sections

  • Condensation damage from low flue gas temperatures

  • Incorrect liner sizing

  • Lack of proper connector pipes and slope

If the liner is unsafe or incompatible, we recommend stainless steel chimney relining, customized to match your appliance’s BTU output and code compliance.

Combustion Safety and Draft Testing

Our inspections include verifying safe combustion and draft performance and ensuring harmful gases are adequately expelled. We test for:

  • Adequate draft pressure

  • Backdrafting or spillage

  • Carbon monoxide readings near the appliance

  • Soot or residue at appliance connections

Draft failure is a hidden danger in many homes. Whether due to an obstructed flue or negative air pressure indoors, it can cause exhaust to flow back into your home. Our inspections detect these issues early.

Digital Chimney Reports with Photos & Recommendations

After every inspection, you receive a clear, photo-documented digital report with:

  • The current condition of your appliance flue

  • Photos of any damage or deficiencies

  • Code-based recommendations for repairs or upgrades

  • Cost-effective solutions tailored to your system

We believe in full transparency. Our reports give you confidence in your next steps, whether selling your home, installing a new appliance, or ensuring household safety.

FAQs About Appliance Chimney Inspections

Do I need to have my chimney inspected if I don't use a fireplace?
Yes. If your furnace, boiler, or water heater vents through a chimney, it still needs inspection. Even unused flues can become blocked, damaged, or hazardous.

How often should appliance flues be inspected?
Annual inspections are recommended by the NFPA and most appliance manufacturers—especially in homes with older masonry chimneys.

What happens if I don’t reline my chimney for my new furnace?
Improper flue sizing or unlined flues can lead to poor drafts, condensation damage, and carbon monoxide exposure. Relining ensures compliance and safety.

Top 10 Questions Homeowners Ask About Furnace & Water Heater Chimneys

Expert Answers from the Chimney Bear Team in Westchester, IL

If your furnace, boiler, or water heater vents into a chimney, that chimney is as crucial to your home’s safety and efficiency as the appliance itself. At Chimney Bear, we regularly inspect appliance chimneys throughout Burr Ridge and the surrounding Chicagoland area, helping homeowners avoid dangerous carbon monoxide exposure, costly repairs, and inefficient heating systems.

Our appliance chimney inspection service costs $165.00 and includes a complete visual and camera inspection, a draft assessment, and a detailed digital report. Below, we answer the top 10 most common questions from homeowners like you.

1. Does my furnace or water heater vent through the chimney?

Yes—if you live in an older home, your gas appliances may vent through a masonry chimney.

Many homes in Alsip and nearby communities were built before direct-vent or high-efficiency appliances became the standard. Suppose your water heater or furnace is atmospheric-vented (meaning it relies on natural draft to vent exhaust gases). In that case, it’s likely connected to a chimney—often the same one used by a fireplace.

We often find that these older systems weren’t built to accommodate modern appliances, so proper inspection is essential. Venting through an aging, oversized, or deteriorated chimney can lead to carbon monoxide risks, condensation damage, or appliance failure.

2. Why is there condensation or water in my chimney?

Condensation is common, especially when modern appliances are vented into unlined chimneys.

High-efficiency furnaces and water heaters produce cooler exhaust gases. When those gases enter a cold, oversized masonry flue, they don’t rise quickly. Instead, they linger, cool further, and condense on the chimney walls. This condensation is slightly acidic and can cause rust on metal parts, deterioration of mortar joints, and even mold or mildew in the surrounding structure.

We see this issue frequently during appliance changeouts where the chimney wasn’t inspected or relined. During our inspection, we check for signs of past condensation and recommend solutions like stainless steel chimney liners to prevent further damage.

3. Can a clogged chimney cause my furnace or water heater to shut down?

Yes, and it can be dangerous.

When a chimney is blocked—by soot, animal nests, masonry collapse, or debris—your furnace or water heater may shut off automatically as a safety measure. These appliances are designed to sense when exhaust gases aren't venting properly, which could lead to deadly carbon monoxide buildup inside your home.

We’ve helped many customers resolve strange appliance shutdowns by identifying and clearing blockages during inspection. If your water heater or furnace has been behaving unpredictably or your CO detector is going off, schedule an inspection immediately.

4. What are the signs of a venting problem?

We recommend watching for these common red flags:

  • Rust on flue connectors, vent pipes, or appliance tops

  • Soot or scorch marks around venting connections

  • Unusual smells—like exhaust, burning, or gas

  • Condensation on the appliance or chimney face

  • CO detector alerts or headaches/fatigue in your household

If you notice any of these signs, don’t wait. We treat venting issues with urgency. Our inspection will identify the source of the problem and help you prevent more serious consequences like appliance failure or carbon monoxide poisoning.

5. Is it safe to vent a new furnace into an old chimney?

Only if the chimney is inspected correctly and, if necessary, relined.

Many older chimneys were built for wood-burning appliances or low-efficiency furnaces that produced hotter exhaust. When a new, high-efficiency unit is installed without updating the chimney, the result can be poor draft, condensation, or even carbon monoxide leakage.

We strongly advise anyone replacing a furnace, boiler, or water heater to schedule a chimney inspection first. Our team will verify that the flue is adequately sized and structurally sound for your new appliance—and if it’s not, we’ll recommend code-compliant options such as a stainless steel liner to ensure safety and performance.

6. How often should I inspect the chimney for my furnace or water heater?

Annually.

Even if you never use your fireplace, your chimney needs regular inspection if it vents any gas appliance. The National Fire Protection Association (NFPA) recommends annual chimney inspections, and so do we—especially in Chicagoland, where seasonal temperature swings can accelerate chimney wear and tear.

At Chimney Bear, our appliance chimney inspection includes:

  • Full visual and camera inspection

  • Flue liner condition analysis

  • Draft testing and airflow assessment

  • Identification of any blockages or deterioration

  • A digital report with photos and recommendations

This small annual investment helps avoid significant safety risks and costly appliance damage.

7. Do I need a chimney liner for my gas furnace or water heater?

In most older homes—yes.

A properly sized and installed chimney liner ensures that your furnace or water heater vents exhaust safely and efficiently. Without a liner, the flue gases may:

  • Linger and condense, damaging masonry

  • Corrode chimney walls over time

  • Leak carbon monoxide into your living space

  • Reduce draft, impacting appliance performance

If your chimney lacks a liner—or has a cracked, oversized, or clay tile liner—it may be putting your home at risk. We evaluate the liner during inspection and recommend stainless steel relining when appropriate. This protects your appliance investment and ensures code compliance.

8. Can I vent the furnace and water heater through the same chimney?

Yes, but only under the right conditions.

This is a widespread configuration in St.Charles homes, especially in basements where space is limited. However, the chimney must be:

  • Properly sized for the combined BTU output of both appliances

  • Equipped with correctly installed connector pipes

  • Free of blockages or deterioration

  • Inspected regularly for draft performance and flue condition

If the setup is not installed to code, it could lead to back-drafting, where carbon monoxide leaks back into your home instead of safely exiting through the flue.

Our team checks these conditions during your inspection and advises whether relining, resizing, or separation is required.

9. What happens if I don’t fix a chimney venting issue?

The consequences can be severe—and expensive. Ignoring chimney problems that affect your furnace or water heater can lead to:

  • Carbon monoxide poisoning

  • Appliance failure or premature replacement

  • Water damage from condensation

  • Masonry deterioration and structural issues

  • Violation of local safety codes

  • Higher energy bills due to poor draft performance

It can even lead to extreme fires or dangerous flue gas exposure. The cost of not inspecting your chimney far outweighs the $165 it takes to identify and correct issues early.

10. How much does inspecting or relining a chimney for appliances cost?

Our appliance chimney inspection service costs $165.00 and includes everything needed to assess the safety and performance of your flue. This includes:

  • High-definition internal camera inspection

  • Digital draft and combustion safety check

  • Moisture and corrosion evaluation

  • Detailed report with photos and expert recommendations

Relining costs depend on factors like chimney height, number of appliances, and liner size. On average, relining starts around $1,500–$2,500 but varies per home. Our reports provide transparent pricing with no pressure—just facts and options so you can make informed decisions.
