Inspects the flue and chimney for blockages, corrosion, partial or complete disconnections, and loose connections.
Checks the vent terminal for nests, which the CPSC says block exhaust gases and send them into the home.
Confirms the vent type fits the furnace: metal or Type B for Category I, PVC or ABS for Category IV.
Compares the combustion air supply with Section 9.3 of NFPA 54, the standard the manual names.
Tests the pressure switch, main limit, and rollout switch, the controls the manual says not to bypass.

Looks for back-drafting and leaks at the furnace, 2 indoor carbon monoxide sources the EPA lists.
Compares your alarm locations with the CPSC placement: every level of the home and outside sleeping areas.
Commonly extra: flue or vent repairs, a heat exchanger or a furnace replacement after a defect, and repairing a gas furnace with a failed control. A cracked exchanger can turn an inspection into a replacement talk, so ask what each extra costs before you approve it.
Ask whether the inspection covers the flue, the vent terminal, and every safety control.
(901) 613-0388Local Furnace Issues and What Your HVAC Company Does
The table pairs 5 inspection findings in Collierville, TN homes with what the HVAC company does next.
| What you notice | What your HVAC company does |
|---|---|
| A vent pipe is loose, corroded, or disconnected | The company keeps the furnace off until the vent is repaired. The EPA names blocked, disconnected, and leaking flues as carbon monoxide sources. |
| An 80% furnace vents into an unlined masonry chimney | A local HVAC company recommends a listed metal liner or Type B vent, since the manual prohibits venting into an unlined masonry chimney. About 11.0% of Collierville homes date to 1979 or earlier, per the Census. |
| The rollout switch has tripped more than once | The company looks for the source of the rollout in the burner area and the vent. The manual names flame rollout as the overheat that opens this switch. |
| A gas smell near the furnace | MLGW, the gas utility here, tells you to leave and call (901) 528-4465 from another location, and furnace smells covers the other odors. The furnace gets inspected once the utility clears the home. |
| A level of the home has no CO alarm | The company points to the CPSC placement: battery or battery-backup alarms on every level and outside sleeping areas, away from heating vents. Before the visit, we recommend one alarm outside each sleeping area, as the CPSC advises. |

What Affects the Price of a Furnace Safety Inspection
No allowed source publishes a Collierville, TN price for a furnace safety inspection. An 80% furnace on a masonry chimney adds a liner check, so mention the chimney when you call.
Factor 1
Vent Length and Type
A long Category I metal flue or a Category IV PVC run adds joints and terminals to inspect.
Factor 2
Masonry Chimney Venting
An 80% furnace vented through a masonry chimney calls for a liner check, since the manual prohibits an unlined masonry chimney.
Factor 3
Shared Vents
A vent shared with a second gas appliance adds that appliance's connection to the check.
Factor 4
Defects Found
A disconnected flue, a failed switch, or a cracked exchanger turns the inspection into a repair or replacement decision.
Ask how a vent defect or a cracked exchanger found on the visit changes the price, and what the next step costs.

Questions Before You Call
Open any question below for its answer
Is a Furnace Safe to Run After a Failed Inspection?
No, not until the defect is repaired and the HVAC company retests the furnace and finds it safe to run. The CPSC says not to operate a malfunctioning appliance until trained personnel have serviced it.
How Much Deposit Can a Tennessee Home Improvement Contractor Take?
A Tennessee home improvement contractor can take no more than one-third of the contract price as a deposit, unless an exception such as bonding applies. Tennessee's home improvement law covers central heating installation in counties that adopt it. Get the deposit terms in writing before you approve a replacement.
Can You Cancel a Furnace Contract Signed at Your Door in Tennessee?
Yes, Tennessee law lets a buyer cancel a home solicitation sale until midnight of the third business day after signing. A signed, dated emergency waiver ends that right once the seller has made a substantial start. Read the terms in writing before you sign.
Does a Carbon Monoxide Alarm Belong Right Next to the Furnace?
No, the CPSC advises alarms on every level of the home and outside sleeping areas. It tells you to avoid spots near heating vents. The company checks your alarm placement during the inspection.
Why Does a Furnace Inspection Check the Outdoor Vent?
Birds, other animals, and insects nest in vents and block exhaust gases, sending the gases into the home, per the CPSC. A local HVAC company checks the vent terminal for nests and debris during the inspection.
