Should you repair or replace your furnace?

Choosing between repairing or replacing your furnace can feel like a significant decision. At GoMaxAir, customers want honest, professional advice without pressure. With over 40 years of combined experience in the HVAC industry, we’ve helped countless homeowners in Anne Arundel County and surrounding areas make the right choice for their heating systems. 

In this guide, we’ll break down the key factors to consider when deciding whether to repair or replace your furnace.

1. Age of Your Furnace: The 15-Year Rule

The age of your furnace is one of the primary indicators of whether it’s time to repair or replace it. Most furnaces have a lifespan of 15 to 20 years with regular maintenance. If your furnace is over 15 years old, replacing it might be more cost-effective, especially if it’s showing signs of reduced performance. Older furnaces also tend to have lower energy efficiency ratings than newer models, which means they’re likely costing you more energy bills than they should.

Tip: A furnace’s age can usually be found on a label on the unit. If you’re unsure, GoMaxAir’s technicians are here to help assess your system.

2. Repair Costs: When They Add Up

A good rule of thumb when it comes to repair costs is the “50% rule.” If the repair cost is 50% or more of the price of a new furnace, replacing it may be the better option. Frequent repairs are often a sign that the furnace is nearing the end of its lifespan and may soon require additional costly repairs.

For instance: If a new furnace costs $3,500 and the repair estimate is $1,800, replacement is likely more economical in the long run.

At GoMaxAir, we always prioritize providing customers with honest assessments, and because our technicians are paid hourly instead of by commission, you can trust that our advice is tailored to your best interests.

3. Are Your Heating Bills on the Rise?

Heating bills can be a major indicator of your furnace’s health. Older or malfunctioning furnaces often require more energy to heat your home, which can result in higher monthly bills. Today’s furnaces are built with advanced energy-saving technology, and the annual fuel utilization efficiency (AFUE) rating on a new furnace will be significantly higher than one that’s 15 years old.

Benefits of upgrading to an energy-efficient furnace:

• Reduced energy bills, which could lead to annual savings
• Lower environmental impact due to decreased energy consumption. 
• Potential for rebates or tax incentives with the purchase of certain high-efficiency models.

4. Are You Getting the Heat You Need?

Comfort is key when it comes to your heating system. If you’re experiencing uneven heating, longer times to warm your home, or frequent cycling on and off, it might indicate that your furnace is no longer able to meet your comfort needs. Additionally, older furnaces may contribute to poor indoor air quality, especially if they struggle to maintain proper humidity levels or lack adequate filtration.

A new furnace can offer better control over your home’s temperature, increased comfort, and improved indoor air quality—a benefit that becomes even more important if anyone in your household has allergies or respiratory issues.

5. Consider Going Green

If reducing your environmental footprint is a priority, a newer, energy-efficient furnace can help you achieve this goal. Modern furnaces use less fuel to produce heat, which results in fewer emissions and less impact on the environment. By replacing an old furnace with a high-efficiency model, you can contribute to environmental sustainability without sacrificing comfort.

6. Addressing Potential Hazards

Safety is a critical consideration in deciding to replace an aging furnace. Older furnaces, especially those nearing the end of their lifespan, have a higher risk of issues like carbon monoxide leaks, which can pose a serious health risk. If you notice any of the following signs, it’s essential to have a professional technician assess your furnace immediately:

• Yellow Burner Flame: The burner flame should be blue. A yellow flame indicates incomplete combustion, which can lead to carbon monoxide leaks. 
• Strange Odors: Persistent burning smells could point to worn-out components or debris within the furnace. 
• Frequent Cycling: If your furnace turns on and off frequently, it may be struggling to maintain the right temperature, which can indicate a failing component.

At GoMaxAir, our technicians are trained to identify these warning signs and provide the safest, most cost-effective recommendations for your home.

7. Reliability and Peace of Mind

Reliability matters. During the coldest months, a dependable furnace is essential to keeping your family safe and comfortable. If your furnace has broken down multiple times or you’re worried about its ability to perform through the winter, replacement can provide peace of mind. A new furnace also comes with a warranty, which can save you money on repairs for years to come.
