Signs You May Need Furnace Installation

Sometimes it’s clear your furnace is on its last leg, but other times, it’s more subtle. If your current system is struggling to keep up, showing signs of age, or just flat-out costing too much, it may be time to consider a full replacement. Here’s what to watch for:

  • Cold Spots or Inconsistent Heat: Rooms that never warm up or temperatures that fluctuate could point to a furnace that’s no longer heating efficiently.
  • Strange Noises: Banging, squealing, or rattling usually means worn-out or damaged internal components and is often a sign it’s time for something new.
  • Sky-High Energy Bills: An old or inefficient system can drive your utility costs up without warning, especially during the colder months.
  • Frequent Repairs: If you’ve had your furnace serviced and repaired more than once in the past year, those repair bills may cost more than replacement.
  • Age Over 15 Years: Most systems last between 15–20 years. If yours is reaching retirement age, upgrading now can prevent an emergency breakdown.

At Legacy Home Service, we walk you through every step, from helping you choose the right system for your home to handling expert installation with care. You’ll get honest advice, clear pricing, and work done by locals who treat you like family. Schedule today and we’ll make sure your home stays cozy for years to come.

Frequently Asked Questions About Furnace Installation

Thinking about upgrading your furnace, but not sure where to start? We’ve answered some of the most common questions homeowners have, so you can move forward with confidence.

Most standard furnace installations in Jefferson and Shelby counties are completed in just one day. Our team arrives on time, preps the space, removes the old unit, and sets up your new system with expert care.

However, if your installation involves switching fuel types, updating your ductwork, or modifying your electrical setup, it may take longer. We’ll always give you a clear, honest timeline so you know exactly what to expect.

Planning ahead for a cozy season or just curious about the price tag? In Alabama, new furnace installations typically land between $2,800 and $6,900, with an average around $4,800.

That range depends on a few factors:

  • The type of furnace: electric models tend to start lower, while gas, propane, or oil units can climb up higher.
  • The size of your home and needed BTUs (more square footage means a bigger, costlier unit).
  • Efficiency ratings: high-efficiency systems cost more upfront but deliver savings through lower energy bills over time.

If you’re curious about your specific home, contact us for a fair estimate and a system that’s right-sized for your family and budget.

In most cases, yes, especially if your current unit is over a decade old. Modern furnaces are designed with energy efficiency in mind, meaning they generate more heat while using less fuel or electricity.

Upgrading to a high-efficiency furnace can make a noticeable difference in your monthly bills, particularly during the colder months. Plus, consistent heating helps reduce wear on your system and creates a more comfortable home overall.

Not always, but it’s a good time to check. If your existing thermostat isn’t compatible with your new furnace, or if it’s outdated and unreliable, we may recommend an upgrade.

Smart thermostats can significantly improve energy management by allowing for scheduling, zoning, and real-time temperature adjustments, even when you’re away. We’ll help you choose the right setup for your home and make sure it works seamlessly with your new system.

If your furnace breaks down in the middle of a cold snap, you can’t afford to wait. Legacy Home Service offers priority scheduling for emergency furnace replacement to help keep your family safe and warm.

We’ll work quickly to assess the issue, walk you through your best replacement options, and get your new system installed as soon as possible, often within 24 hours. As a VIP member, you’ll automatically move to the front of the line for emergency service and won’t pay extra service fees.
