Is It Time for a Furnace Replacement?
How to Tell When Repairs Aren’t Enough
Furnace replacement is your best option when repairs are no longer enough. Even if you’ve been diligent with regular maintenance, heating systems don’t last forever. The older your furnace, the more costly repairs may be and the more strongly your heating contractor may suggest furnace replacement.
And, no matter how much you’re willing to invest in another repair, it won’t turn back the clock and restore the unit’s original state. It also won’t match the performance and efficiency improvements of the latest models. Furnaces are complex systems. They have lots of parts that may need to be repaired. But we’ll determine when repairs aren’t enough to keep your heating unit going.
When to Choose Furnace Replacement Over Furnace Repair
The Unit’s Near the End of Its Life Expectancy
The average furnace lasts 15 to 20 years. Some units can operate up to the 30-year mark. By this point, they are likely to need more repairing. Plus, the requirements have changed considerably over the past few years. The Federal Trade Commission requires furnaces to have an annual fuel utilization efficiency (AFUE) rating.
An older gas furnace may have an AFUE of as low as 56%. This doesn’t meet today’s standards. A new furnace or boiler must have at least an 80% AFUE, while high-efficiency units may be rated up to 98% AFUE. The higher the number, the more a new heating unit can lower your energy bills (and, you avoid spending thousands of dollars on repairs).
Your Furnace Makes Unusual Noises
Noise from a furnace almost always indicates a mechanical issue. If the unit is just a few years old, dirt may be the cause. A technician can clean the inside of the system. However, if you have an older furnace, screeching, popping, banging, or squealing sounds can mean it’s overheating. Once metal overheats, it expands, which can cause it to crack or grind against other components.
Thumping or grinding sounds can mean the blower motor is failing. Replacing it is an expensive repair. Excessive popping, banging, or rumbling can mean the burners are malfunctioning or there’s an issue with the combustion chamber. Clicking sounds often mean the compressor is failing. A repair in these cases isn’t enough or may be too expensive to consider (which leads to the next reason to consider furnace replacement).
Repair and Maintenance Costs Are Too High
If you have an old furnace, always compare the repair cost to what you’d spend on a new unit. A furnace repair can cost hundreds, if not thousands, of dollars. Your heater will probably need more repairs in the future if it’s near or over 15 years old. Some experts say to replace a furnace if repairing it costs 30% of the price of a new unit; others suggest going by the 50% rule.
Your budget can dictate which decision makes sense. However, the older your furnace, the less sense it makes to invest in a costly repair. Your local heating contractor can also help make a decision based on the type of repair it needs. However, spending $5,000 on furnace replacement often has more long-term benefits than shelling out $2,000 to fix an older model.
Inadequate or Uneven Heating
A lack of heat, no matter how high you set the thermostat, is a sign your furnace is failing. Uneven heating can leave some rooms unbearably hot and others freezing. This is symptomatic of a poorly functioning furnace (unless a closed damper or minor issue is the cause). The unit should be replaced, especially if it’s nearing the end of its lifespan and has other problems.
Your Home Has Poor Indoor Air Quality
Poor indoor air quality (IAQ) can cause allergies and various illnesses. Pollutants generated by oil and gas furnaces can be harmful to your health. If the furnace is no longer venting flue gases outside, these combustion byproducts can remain inside or blow back in.
Increased humidity is another sign of a failing gas furnace. To make matters worse, humid air can help hold in toxic fumes. Carbon monoxide is also an IAQ concern that is best addressed with furnace replacement and other HVAC improvements.
Energy Costs Are Increasing
Your utility bills can fluctuate depending on the season (or if your furnace is running more frequently). However, they shouldn’t change dramatically from the same month last year. If your energy bill is suddenly hundreds or thousands of dollars more per year, contact your local heating repair company. Replacing an older, less efficient furnace may be the best solution for keeping energy costs in check.
The Warranty Has Expired
Furnace warranties cover many parts and repairs. They can save you a lot if your heating unit is installed properly and you’ve kept up with maintenance. However, if the warranty is no longer valid or has expired, paying out-of-pocket can mean wasting money that can be put to better use. You’ll also get a new warranty with your new furnace. Also, a home warranty may cover part of the cost of furnace replacement, depending on the coverage.
The Furnace Breaks Down When You Need It the Most
Older units tend to fail during times of peak demand. If your 10- to 15-year-old furnace breaks down during a cold spell, it probably can’t work as hard as it once did. If it’s been repaired before, additional services will be needed again, even if it can be fixed. Also, consider your heating contractor’s higher service costs during the in-season. Replacing your furnace before installers are in high demand can save money, so it helps to realize in advance when repairs may not be enough.
