Benefits of Furnace Replacement

First is the cost—both upfront and monthly—and second, your overall heating needs. In cold climates like Michigan, you’ll be best served by spending extra for a higher-efficiency, better-performing unit. The amount of time you’ll be using it during our harsh winters means that increased efficiency (and lower monthly bills) will outweigh the value of cutting upfront costs.

Also, the lower-efficiency units don’t distribute heat as well as the high-efficiency units, so they make for a less comfortable home.

One measure you’ll see a lot when researching furnace replacement is AFUE, which stands for annual fuel utilization efficiency. AFUE is calculated by taking the amount of energy output by a furnace and dividing that number by the amount of energy that was needed to produce the energy output. So, a furnace with 90% AFUE outputs 90 BTUs with an input of 100 BTUs. The missing 10 BTUs is wasted energy.

Is It Time for a Furnace Replacement?

Sometimes it’s obvious, like when the cost of furnace repair is almost half of what replacing the furnace would cost. Other times, it’s not so obvious. Even if the cost of repairing your furnace is fairly low, you might want to consider a replacement. Especially if it’s an older unit, because chances are it’s going to have more issues in the future, and those repairs start to add up.


Factor in the increased monthly cost of running an old, lower-efficiency unit, and it may become clear that it’s time to consider a furnace replacement. And besides making financial sense, you’d be amazed at the increase in comfort level you’ll experience with the superior heating capabilities of newer units.

Common Signs Include:

  • The unit is more than 15 years old. Furnaces, like most things in life, will eventually need to be replaced.
  • Your energy bills are skyrocketing. An inefficient furnace will likely result in energy bills that are significantly higher than what you’re used to.
  • There’s a lot of dust in your home. Dust is a normal part of being a homeowner, but if you notice a drastic increase of dust around your home, something is probably wrong with your furnace.
  • Your furnace isn’t cycling properly: It’s always a good idea to test your furnace before the cold weather hits. If it cycles on and off regularly or if it is constantly running when it doesn’t need to be, consider calling our team at Briarwood for furnace replacement in Rochester, Rochester Hills & Oakland Township.

Frequently Asked Questions

  • How do I know if my furnace needs repair or replacement?

    If your furnace is struggling to keep your home warm, making unusual noises, or requiring frequent repairs, it may be time for a professional evaluation. Older furnaces that are less efficient can also lead to higher energy bills and inconsistent comfort throughout your home.

    In many cases, a repair is all that’s needed. However, if your furnace is over 15–20 years old and breaking down often, replacement may be the more cost-effective option in the long run. At Briarwood, we’ll always explain your options clearly and help you make the choice that’s best for your home and budget.

  • Why is my furnace blowing cold air?

    A furnace blowing cold air can be caused by several things, including a dirty air filter, thermostat settings, or a problem with the ignition or burner. Sometimes, the furnace is actually working as designed but cycling between heating cycles.

    If the air stays cold or your home isn’t warming up, that’s a sign something isn’t right. Our technicians see this often during Michigan winters and can quickly diagnose whether it’s a simple fix or something that needs attention.

  • How often should my furnace be serviced?

    We recommend having your furnace serviced once a year, ideally in the fall before the heating season begins. Regular maintenance helps catch small issues early, improves efficiency, and extends the life of your furnace.

    Annual service also helps ensure your system is running safely — something especially important during long Michigan winters when your furnace works overtime.

  • How long does a furnace typically last in Michigan?

    Most furnaces last 15 to 20 years, depending on usage, maintenance, and system quality. Because Michigan winters are tough on heating systems, furnaces here often work harder than in milder climates.

    Routine maintenance can help your furnace reach the higher end of that lifespan. If your system is getting older and you’re noticing frequent repairs or rising utility bills, it may be time to start planning ahead.

  • Why is my furnace making strange noises?

    Unusual sounds like banging, rattling, squealing, or humming can indicate loose components, airflow issues, or mechanical wear. While some noises are minor, others can signal a more serious problem if ignored.

    If your furnace suddenly sounds different than normal, it’s best to have it checked sooner rather than later. Catching the issue early often prevents more expensive repairs down the road.

  • What can I do to improve heating efficiency and lower my energy bills?

    Simple steps like changing your furnace filter regularly, keeping vents clear, and scheduling annual maintenance can make a big difference in efficiency. Using a programmable or smart thermostat can also help reduce energy use when you’re asleep or away.

    If your furnace is older, upgrading to a high-efficiency system may significantly lower heating costs. We’re always happy to walk through options that make sense for your home — no pressure, just honest advice.

  • Do you offer emergency or after-hours heating service?

    Yes — we know furnace problems don’t always happen during business hours. That’s why Briarwood offers 24/7 emergency heating service when you need it most.

    As a family-owned company, we understand how important it is to keep your home warm and safe, especially during extreme winter weather. When your heat goes out, we’re just a phone call away.
