Most homeowners do not start thinking about furnace replacement until something feels off. Rooms that never quite warm up. A system that runs constantly. Repairs that keep coming back. In Lexington and across Central Kentucky, those issues tend to show up right when the weather turns colder, usually when the system is already under the most stress.
Fayette Heating & Air provides furnace replacement services for homeowners throughout Lexington, Elsmere, and surrounding areas. We focus on getting the basics right, proper sizing, clean installation, and systems that hold up during Kentucky winters. No upselling. No guessing. Just a furnace that works the way it should, day after day.
Is Repair Still Worth It? Know When to Choose Replacement.
Some furnace problems are worth fixing. Others are a sign that the system is reaching the end of the road.
Replacement is often the better option when you start seeing patterns like:
- The furnace is 15 years old or older
- Breakdowns happen more than once in a season
- Energy bills keep climbing without a clear reason
- Certain rooms stay cold no matter how long the system runs
- Safety issues come up during inspection
In Central Kentucky, waiting too long can mean dealing with a failure during the coldest part of the year. Replacing before that happens gives you more control over timing, system selection, and scheduling.
Precision Furnace Installation is Key to Long-Term Efficiency
A new furnace is only as good as the way it is installed. Even a high-efficiency system will struggle if it is the wrong size or poorly connected.
Before recommending a replacement, we take a close look at the home and perform a Manual J load calculation. That tells us how much heat the home needs. Not what the old unit was rated for. Not a rough estimate based on square footage alone.
Too large and the furnace short cycles. Too small and it never catches up. Getting the size right helps with comfort, efficiency, and long-term reliability.
We also make sure the new system works smoothly with your existing ductwork, thermostat, and fuel source so there are no surprises once it is running.
Understanding Your Furnace Replacement Options
Modern furnaces are more efficient and quieter than older models, but not every home needs the same setup.
Common options include:
- Single-stage furnaces that turn on and off as needed
- Two-stage furnaces that run at lower output most of the time
- Variable-speed furnaces that adjust gradually for steadier comfort
Efficiency is measured by AFUE ratings. Higher ratings mean less wasted fuel. We explain what those numbers mean in real terms and help you decide what makes sense for your home and budget, without pushing features you may not need.

Furnace Replacement FAQs
When should I replace my furnace?
If your furnace is 15-20 years old, needs frequent repairs, has high energy costs, heats your home unevenly, or makes unusual noises consistently, it is likely time for a new furnace.
How much does furnace replacement cost?
Furnace replacement typically costs between $2,800 and $6,800. Most homeowners should expect to pay around $4,650 on average. This number depends on furnace size, fuel type, and efficiency ratings.
How long does installation take?
A new furnace installation should take between 4 and 10 hours, with 10 hours being a rarity. Don’t worry, a furnace replacement isn’t a process that takes days or weeks to complete.
What maintenance is required after a new furnace installation?
After furnace replacement, it’s important to schedule annual maintenance for your new unit. Typically, having your furnace checked once per year will keep it running smoothly and efficiently. If you use your furnace often, you may need a check-up twice per year.
