How Long Can I Expect My Furnace, Boiler or Air Conditioner Unit to Last?

There's probably nothing that contributes more to the comfort we feel in our homes than the ability to monitor and control the inside temperature – to stay warm when it's frigid outside and to escape the sweltering heat of a hot summer day. It's hard to imagine what life was like before HVAC systems became commonplace. Because of the importance we place on keeping warm or staying cool, most of us ensure our heating and cooling systems are properly maintained and any necessary repairs are promptly completed. Even so, there will come a time when you’ll need to replace your existing system.

At NJR Home Services (NJRHS), we understand the importance of protecting your home heating and cooling systems. This page answers important questions to help you proactively monitor your heating and cooling systems and make the right decisions.

Time for a New Furnace or Air Conditioner?

How can you, as a homeowner, know it's time to install a new furnace, boiler or air conditioner? How long can you reasonably expect your current system to function efficiently?

Before answering those questions, let's clear up an important matter — you may not realize it, but your home heating and cooling systems are designed to work together. If you need to install a new furnace, boiler or air conditioner, there can be significant benefit to replacing both at the same time. Technology has improved dramatically over the past decade, so a new unit can be more efficient. Installing heating and cooling systems that complement each other also ensures maximum air flow, which leads to lower energy bills. In addition, matching the capacity of your furnace to that of your AC unit can prevent your coil from freezing, which will also save you the cost of a new coil; most manufacturers don't offer warranties on "coil-only" replacement.

So how long should your furnace, boiler or air conditioner last? You don't want to replace a unit too early and lose a few years of useful life. On the other hand, you don't want to hold off too long and end up without heat or cool air for days.

How Will I Know That It's Time for a New Heating and Cooling System?

Here are the early indicators that your HVAC unit may be getting toward the end of its useful life:

  • You have had the unit repaired more than once in the last two years. Your furnace, boiler and air conditioner all have many moving parts, which are subject to wear and tear, so it's not uncommon to replace parts as your unit gets older. If you've had more than one major repair over any two year period, you may want to consider a new unit.
  • You hear banging, clanging, squealing, whistling, rattling or other odd noises emanating from your furnace, boiler or air conditioner on a regular basis. A healthy HVAC unit shouldn't make these noises.
  • Your energy bills have gone up significantly with no corresponding change in the weather. Loss of efficiency is one of the characteristics of old age in a heating and cooling system — your unit will have to work harder and harder just to keep up.
  • Is your blower running all the time? A continually running blower may be a sign of other, more serious problems. It's always smart to have your system checked.

How Long Should I Expect My Water Heater to Function Efficiently?

Whether it's for a hot shower, to run the dishwasher or to do a load of laundry, there's little that's more frustrating than a water heater that's not doing its job. But water heaters don't last forever, either. Just like your HVAC unit, they have a useful life. Unfortunately, though, the expected efficiency of a water heater is significantly less than a furnace, boiler or air conditioner — usually around 10 years.

How Will I Know When I Need to Install a New Water Heater?

Here are the warning signs that your water heater may need to be replaced:

  • Water temperature problems. If your water takes a long time to heat up or simply won't get as hot as it once did, that may be a sign you need to replace it.
  • The tank has been compromised. If there's evidence of a leak or a drip — puddles or water stains under the tank, for example — it may be time to replace the unit.
  • The tank is deteriorating. Rust or corrosion indicates a breakdown of the metal in your tank.
  • Sediment and mineral buildup. Every water heater tank accumulates some mineral deposits or sediment. The more you have in your tank, the less efficient the water heater will be. In some instances, you can alleviate the problem by flushing your tank, but some sediment buildup can be significant. Pour a glass of cold water and a glass of hot water and set the two side by side. If the cold water is clear, but the hot water is cloudy or discolored, that's a sign that you have a significant buildup of sediment in your tank.
