Replacing your furnace this fall in DeSoto County, MS: a practical guide
By the RW Heating, Air, Plumbing & Electrical Team · Reviewed by our NATE-certified technicians · Serving DeSoto County since 1999
Signs your furnace is near the end
Furnaces usually give you warning signs before they fail. Replacement is typically the smarter move when you notice:
- The furnace is 15 to 20 years old or more
- Heating bills are climbing even though usage has not changed
- You are calling for repairs more than once a season
- The burner flame is yellow instead of blue, which can indicate a combustion issue
Furnace or heat pump for our climate?
North Mississippi has mild winters, which makes heat pumps a strong option for many homes. Gas furnaces still make sense where gas is already installed or in homes that prefer that style of heat.
| Gas furnace | Heat pump |
|---|---|
| Best in colder spells, existing gas homes | Best for mild winters like ours |
| Runs on natural gas or propane | Runs on electricity |
| No cooling function | Heats and cools year-round |
Modern heat pumps also use updated low-emission refrigerants required in newer systems. We help homeowners compare both options based on budget and comfort goals.
Sizing, efficiency, and cost
Proper furnace installation requires a load calculation, not guesswork. Equipment must match your ductwork and home size to perform efficiently.
Federal energy-efficiency tax credits ended on December 31, 2025, so planning should be based on full installed cost. We also offer financing options when needed.
See our furnace installation page for full process details.
Common questions
How long does a furnace last?
A well-maintained furnace typically lasts 15 to 20 years. After that, efficiency drops and failure risk increases.
Should I get a furnace or a heat pump?
Heat pumps are often ideal for our mild winters because they heat and cool efficiently. Furnaces are still a strong choice for gas homes or colder-weather preference.
When should I replace it?
Fall is the best time. It allows installation in mild weather instead of an emergency replacement in winter.
