When Is It Time to Replace Your Gas Furnace?
Four Clear Signs
It's time to replace your gas furnace when it's 15 to 20 years old, has a cracked heat exchanger, needs a major part like an inducer motor or gas valve, or keeps failing every winter.
| Sign | Why It Matters |
|---|---|
| 15 to 20+ years old | Near the end of normal furnace life |
| Cracked heat exchanger | Carbon monoxide risk |
| Major part failed | Inducer, gas valve or board on an old furnace |
| Yearly breakdowns | Repairs add up |
| Uneven heat, rising gas bills | Lost efficiency |
Can a Furnace Last 25 Years?
Some gas furnaces last 25 years, especially in mild climates where they don't run much. Age alone isn't a reason to replace a safe, working furnace.
- Keep a safe, working furnace with yearly tune-ups.
- Replace when safety, major parts or efficiency say so.
- Pair the decision with your AC's age.

Is a High Efficiency Furnace Worth It Here?
A high efficiency furnace is worth it in the Lowcountry only sometimes, because mild winters mean your furnace runs fewer hours than in colder states.
| Choose 80 Percent When | Choose 96 Percent When |
|---|---|
| Furnace runs only on the coldest days | You heat with gas most of the winter |
| Existing metal flue works well | Venting can run out a side wall |
| Budget is tight | You plan to stay 10+ years |

Dual Fuel: A Heat Pump Paired With Your Furnace
Lower Winter Bills
Dual fuel pairs a heat pump with a gas furnace. The heat pump handles most of the winter, and the furnace takes over on the coldest nights.
| Setup | Cooling | Mild Winter Days | Coldest Nights |
|---|---|---|---|
| Furnace and AC | AC | Furnace | Furnace |
| Dual fuel | Heat pump | Heat pump | Furnace |
| Heat pump only | Heat pump | Heat pump | Heat pump plus heat strips |

Frequently Asked Questions About Furnace Replacement Near You
Quick Answers
How Long Does a Furnace Replacement Take?
Most furnace replacements take one day. Venting changes or dual fuel can add a day.
Do I Need to Replace My AC Too?
Not always, but the new furnace has to work with your AC coil. If the AC is the same age, replacing both usually makes sense.
Can I Switch From Gas to a Heat Pump?
Yes. Many Lowcountry homes switch to a heat pump or go dual fuel.
Do You Pull Permits?
Yes, for every furnace replacement.
Will a New Furnace Lower My Gas Bill?
A higher efficiency furnace burns less gas for the same heat, so yes, especially if you heat with gas most of the winter.
Which Furnace Brand Do You Put In?
We put in American Standard gas furnaces, and we're one of the brand's Customer Care Dealers.
Can I Spread the Furnace Cost Out?
Yes. Service Finance offers 0% for 12 months and longer, lower-payment plans on approved credit.
