Gas Furnace Repair in Collierville, TN Homes
Call us, and a local HVAC company comes on the line. Gas heats 61.0% of Collierville homes.
Gas furnace repair in Collierville, TN starts with readings, since gas heats 61.0% of the Town's 18,161 occupied homes. A local HVAC company measures the temperature rise against the nameplate and tests the ignition parts and safety switches before it replaces anything. We suggest one question for the call: which reading pointed to the failed part?

- Homeowners with a gas furnace
- You live in 1 of the 11,073 Collierville homes heated by utility gas, and the furnace runs without heating or shuts down mid-cycle.
- Condo and townhome owners
- Tennessee condo law makes you responsible for your own unit's furnace, and the association for the common elements, unless the declaration says otherwise.
- Landlords who own houses or small rentals
- Tennessee's landlord and tenant act names heat an essential service. The act reaches Shelby County, whose 2010 count of 927,644 clears its 75,000-person line. Renters, tell your landlord about the failed furnace first.
Inside a Standard Furnace Repair
A local HVAC company handles 7 tasks on a standard gas furnace repair, per the manufacturer's manual and the CPSC:
Measures the temperature rise and compares it with the range printed on the furnace nameplate.
Tests the hot surface igniter, which stays powered until the flame sensor proves flame.
Checks the pressure switch, which closes before the gas valve opens.
Tests the main limit and the rollout switch, the 2 controls that cut the burners on overheat.
Inspects the vent pipe and flue for blockages, corrosion, and loose or disconnected joints.
Confirms the combustion air supply against NFPA 54, the National Fuel Gas Code the manual names.
Restarts the furnace after the repair and reads the temperature rise again.
Commonly extra: ductwork changes, venting conversions, electrical upgrades, and the permit when a repair grows into a replacement. For an attic unit, a Collierville amendment calls for permanent or pull-down stairs to the equipment, so ask about access first.
Ask whether the error code your furnace flashes points to an ignition part or the pressure switch.
(901) 613-0388Local Furnace Issues and What Your HVAC Company Does
The table pairs 5 gas furnace faults with the check a local HVAC company runs for each, per the manufacturer's manual.
| What you notice | What your HVAC company does |
|---|---|
| The blower runs, but the vents blow cool air. | The HVAC company checks the main limit, which cuts the burners but keeps the blower running on overheat. That limit trip is one cause of a furnace blowing cold air. The filter is the one part of that check the manual leaves to you, which is why we list it in the steps below. |
| The burners never light, or light and then shut off. | Your HVAC company tests the 2 ignition parts covered under furnace ignitor and pilot problems. The manual keeps the glowing part powered until the sensor proves flame. |
| The inducer motor runs, but the gas valve never opens. | The company tests the pressure switch, since the gas valve opens only after that switch closes. The manual forbids bypassing it as a fix. |
| The rollout switch has tripped. | A local HVAC company inspects the burners and venting for the cause before any reset. The manual says the switch opens on flame rollout and must not be jumpered. |
| An 80% furnace vents into an older chimney. | The company confirms a listed metal liner or Type B vent, since the manual prohibits venting into an unlined masonry chimney. Census figures date 11.0% of Collierville homes to 1979 or earlier. |
Steps From the First Call
Gas furnace repair follows 4 steps from your first call:
- 1
Call and describe the furnace
You call us about the furnace. We get a local heating and cooling company on the line, so have the model number, any error code, and the filter size ready.
- 2
Check the thermostat and filter
Set the thermostat to heat, then check the filter, a task the manual leaves to owners. The manual says never to run the furnace without a filter.
- 3
Let the company diagnose the furnace
The HVAC company takes readings on the ignition parts, switches, and temperature rise, then explains the repair it recommends. Ask for a written estimate before work starts.
- 4
Confirm the repair at restart
The company restarts the furnace and compares the temperature rise with the nameplate range again. Ask for those readings in writing.
What Shapes the Price of Gas Furnace Repair
No allowed source publishes a typical range for this repair in Collierville, TN, so 5 factors set the price. The guide to furnace repair cost covers each one in depth. The Town exempts a repair like this from a permit, so we leave the permit fee off this list.
Factor 1
The Failed Part
Each ignition part, the pressure switch, and each limit switch carry their own part price, and readings confirm which one failed.
Factor 2
Warranty Terms
A manufacturer's warranty can cover the part without the labor, so check whether you pay for labor, as the FTC advises.
Factor 3
Flue Condition
A blocked, corroded, disconnected, or loose flue adds vent work, and the CPSC names those 4 flue faults for inspection.
Factor 4
Attic Access
Collierville's code amendment calls for permanent or pull-down stairs to attic equipment, and the access your home has shapes the labor.
Factor 5
Furnace Category
A 90%-plus model adds a condensate trap and PVC or ABS venting to the checks, while an 80% model uses metal or Type B venting.
Before you approve a part, ask whether the manufacturer's warranty still covers it and whether that coverage includes labor.
(901) 613-0388Codes and Permits That Apply in Collierville
The Town of Collierville exempts normal maintenance and repairs of existing systems from a building permit. Its rules still require a state or county licensed contractor for all mechanical work, so ask the company for its license number.
A change-out needs a Town mechanical permit, and the Town requires a licensed contractor to pull trade permits. When the repair turns into a furnace replacement, the permit holder requests the inspection through iWorQ, by phone, or by email.
A gas smell follows the gas utility's steps first. MLGW tells customers to leave, call (901) 528-4465 from another location, and avoid switching lights or appliances. Piperton and Rossville homes get gas from HFUD instead, so we list its odor line too: (901) 877-6236.
Coverage and Rebate Questions
The sample HO-3 homeowners form excludes mechanical breakdown, so ask your insurer before you count on a claim for a failed part. Warranty, rebate, and coverage answers for Collierville, TN sit in furnace and AC questions. MLGW lists no furnace rebate of its own, so we put the manufacturer's warranty on the failed part first.
Is It Safe to Keep Running a Gas Furnace That Acts Up?
No, not while a safety control keeps tripping or after a carbon monoxide alarm, per the manual and the CPSC. The limit and rollout switches cut the burners on overheat, and the CPSC says not to run a malfunctioning appliance until trained personnel service it. A local HVAC company tests the switches and venting before calling the furnace safe to run.
Ask what each test showed before your furnace runs again.
What Does a Gas Furnace Diagnostic Include?
A gas furnace diagnostic includes readings on the temperature rise, the ignition parts, the pressure switch, and the limit switches, per the manufacturer's manual. The company also inspects the flue for blockages and loose joints, as the CPSC advises. A furnace safety inspection adds the full venting check, so you can ask which reading pointed to the failed part.
Collierville Details That Change the Repair
- The NOAA Collierville station logs 74.5 nights a year at or below 32°F, and January averages a 29.1°F low. Memphis International logs 44.4 such nights, so freezing temperatures are more frequent here than at the airport.
- Electricity heats 37.5% of Collierville homes, yet central heat pumps are 35% of Tennessee's main heating equipment. Before you call, we recommend checking whether yours is an electric furnace or a heat pump.
- When you live in Piperton, TN, your gas comes from HFUD, the Hardeman-Fayette Utility District, which takes gas odor calls at (901) 877-6236.
- Census data dates 55.1% of Collierville homes to 1990 through 2009, so a furnace in one of those houses can be the original unit.

Questions Before You Call
Open any question below for its answer
Can You Reset a Tripped Rollout Switch Yourself?
No, the manufacturer's manual says not to jumper the rollout switch, a manual reset limit that opens on flame rollout. A local HVAC company finds why the flame rolled out before any reset.
Who Pays the Labor on a Furnace Part Under Warranty?
The warranty's written terms decide who pays labor, and the FTC tells buyers to check whether they pay for labor on a warranty repair. One manufacturer's AC warranty, for example, excludes labor for diagnosing and repairing. Have the company check your furnace's warranty terms before work starts.
Which Questions Help Before You Approve a Gas Furnace Repair?
Ask which reading identified the failed part, whether that part is under warranty, and for a written estimate before work starts. The HVAC company explains the repair it recommends from those readings.
What Happens When a Collierville Home's Gas Was Shut Off for More Than 90 Days?
The Town of Collierville requires a $69 Meter Put-back permit, then mechanical and electrical inspections, before service returns. Once the utility restores the gas, have the company check the furnace before the first cold night.
Which Gas Furnace Parts Can Stop the Heat?
The manual names 5 parts in the ignition and safety chain: igniter, flame proving sensor, pressure switch, main limit, and rollout switch. A fault in any one keeps the burners off. Your HVAC company tests each part in order to find the one that failed.
