Repair vs. Replacement: What Does My Heater Need?


Your furnace is giving you flak, but will another repair suffice, or does it have one foot in the grave? It can be difficult to tell when your furnace needs to be replaced, which is why we’re here to help you tell the difference between the need to repair, and the need to replace.

Heating repair in Katy, TX is the first response to a faulty heater, but if it portrays some of these lasting problems, all signs point to a replacement. This is what you need to know.

If Your Furnace is 15 Years Old or More

Some furnaces can last for longer than 15 years with maintenance. You may hear a family friend boast about how their furnace is going on 20 years (and still kicking). The truth is, these aren’t bragging rights; it’s a safety hazard.

After 15 years of service, your furnace not only poses increased risks of danger for you and your family, it will be inefficient compared to how it performed earlier in its life cycle.

At this point, your furnace won’t gain enough efficiency from a tune-up or a single-part replacement. Every component is tired and beginning to wear down. This is when then 50% rule comes into play.

The 50% Rule

If your furnace needs repair, you’ll get a quote from a professional HVAC technician (or several). If you’re quoted 50% or more of the total price of a new furnace, this is your signal.

Your furnace isn’t going to just suddenly stop needing repairs after this point. If you keep repairing an old and faulty furnace, you’re essentially burning money.

While a replacement has a higher upfront cost than a 50% or higher repair bill, newer furnaces won’t break down on you nearly as often as your older unit, saving money over time by reducing repairs.

Additionally, you’ll save money on a month-to-month basis with a new furnace since it will be more efficient in day-to-day operations. It runs for less time to achieve the desired output, and you save money.

Your House Takes a While to Heat Up

Good news: your house is still heating up. This means there shouldn’t be anything majorly wrong with your furnace, although it may indicate a long lapse in maintenance coverage.

Lack of maintenance could mean there’s a need for a few repairs. Each furnace will be different, but these issues normally indicate that while problems are present, they won’t require a completely new system installation.

Strange Noises When You Turn Your Furnace On

There’s nothing wrong with strange noises popping up when you turn on a furnace. Combustion makes noise; there’s no way around that. It’s when those noises persist past the first few minutes of operation.

If these noises continue, or sound noticeably different (or louder) than you’re used to, it’s time to call for repair. This shouldn’t result in a full replacement.

Keep Your Furnace in Tip Top Shape

Keeping your furnace in perfect working order is the best way to avoid early replacements and lower the expected price of your furnace’s lifetime repairs. Don’t skimp on annual maintenance, don’t wait to call for repairs, and you’ll enjoy home comfort from your current furnace for years to come.
