How to Know When It’s Time to Replace Your Furnace

Not sure whether your furnace really needs to be replaced? These are the most common signs we see when it’s smarter to stop repairing — and start fresh with something reliable, safe, and efficient.

Your furnace is 15–20+ years old

Older furnaces lose efficiency, become less reliable, and can even become safety risks as they age.

You've had multiple repairs in the last 2 heating seasons

Frequent breakdowns usually mean deeper issues — and repair costs add up fast.

Uneven heating or cold spots in your home

If some rooms stay cold while others overheat, your system may be struggling to circulate warm air properly.

Rising heating bills with no clear reason

If your usage hasn't changed but your utility costs keep climbing, your furnace may be running inefficiently.

Unusual noises, smells, or cycling issues

Banging, clanking, or burning smells often mean worn-out components or combustion problems.

Constant thermostat adjusting

If you're always fiddling with the thermostat, your system may no longer be keeping up with demand.

Not sure where you stand?

Repair or Replace? Here’s How We Help You Decide

Not sure whether it’s time to replace your furnace — or if one more repair might get you through another winter? You’re not alone. A lot of homeowners face that same question, and the right answer depends on a few key factors.

That’s where we come in. We’ll break it all down so you can make the call with clarity — not guesswork.

Repair vs Replace comparison

Repair Might Make Sense If:

  • Your system is less than 12 years old
  • This is the first issue you've had
  • The repair is minor and affordable
  • It's still heating the home evenly and reliably
  • Your heating bills haven't changed much

Replace Might Make More Sense If:

  • Your system is 15–20+ years old
  • You've had repeated service calls or breakdowns
  • The repair cost is stacking up
  • Certain rooms never feel warm
  • Your heating bills have crept up over time

Our rule of thumb:

If your furnace is over 15 years old and the repair costs more than 25–30% of a new system, replacement is usually the smarter long-term move.

We’ll walk you through both options, explain the numbers, and let you decide what makes the most sense — no pressure, and no sales pitch.

Frequently Asked Questions

Cost & Financing


Furnace installation typically ranges from $4,000 to $9,000+, depending on the size of your home, the system's efficiency (AFUE), and whether ductwork or gas line adjustments are needed. We'll give you a clear, up-front quote — no fluff, no surprises.

Yes — most of our customers choose the $0 down, 0% interest for 12 months option. Approval is quick (about 5 minutes), there are no early payoff penalties, and it won't affect your credit score. We'll walk you through the process and help you find the best option for your budget.

Efficiency & System Selection


AFUE (Annual Fuel Utilization Efficiency) measures how efficiently your furnace converts fuel into heat. In South Carolina, a mid-efficiency model (80–90% AFUE) often makes sense — but a high-efficiency model (95%+) can cut energy bills if you use your system heavily. We'll help you compare the tradeoffs.

Furnace sizing depends on square footage, layout, insulation, and even ceiling height. Bigger isn't always better — we'll calculate the right capacity for your home so you get even heating without wasting money on an oversized unit.

Repair vs. Replace


If your furnace is 15–20+ years old, breaking down often, or heating unevenly, replacement may be more cost-effective than ongoing repairs. We'll walk you through the pros and cons and help you make the right decision.

Timeline & Process


Most furnace installations are completed in a single day. We'll schedule everything in advance, show up on time, and keep the process clean and smooth from start to finish.

Yes — permits are usually required for furnace replacements, especially if gas lines or major electrical work is involved. Don't worry — we handle all the permitting and inspection details for you.

Trust & Qualifications


Most manufacturers offer 10-year limited warranties on key parts — as long as the system is registered and installed by a licensed contractor. We'll make sure everything is properly filed so you're fully covered.

We install trusted brands like American Standard, Trane, and Carrier. We'll help you choose the right fit for your home — no brand favoritism, just honest recommendations.
