How to tell if your furnace is on its last legs — and when repair vs. replacement makes more financial sense.
At ARP Heat And Air, we've been helping Oklahoma homeowners with their HVAC needs since 2011. Our owner Charlie brings 14+ years of hands-on experience and is known for giving honest, practical advice — not trying to upsell you on services you don't need.
Most furnaces last 15-20 years with proper maintenance. If yours is approaching or past that age, it's time to start planning for replacement rather than sinking money into increasingly frequent repairs. A new high-efficiency furnace (96% AFUE or higher) can cut your heating bills by 20-30% compared to an older 80% AFUE system.
If your heating bills have been climbing steadily even though your usage hasn't changed, your furnace is likely losing efficiency. As components wear out, the system works harder to produce the same amount of heat, burning more gas or electricity in the process.
The general rule: if a repair costs more than 50% of what a new furnace would cost, replace it. Also, if you've needed 3 or more repairs in the last 2 years, the system is telling you something. Charlie at ARP Heat And Air will always give you an honest assessment — if a $200 repair will keep your furnace running for 5 more years, he'll tell you.
If some rooms are too hot while others are cold, your furnace may be struggling to distribute heat evenly. This can indicate a failing blower motor, deteriorating ductwork, or a furnace that's simply too old to perform properly.
Banging, popping, rattling, or squealing from your furnace are warning signs. A slight gas smell near the furnace is also concerning and should be checked immediately. These issues can indicate cracked heat exchangers, loose components, or other safety hazards.
