01When the heat quits
Furnace Repair & Replacement
Same-day furnace repair and honest replacement advice for Lansing homes. We fix what can be fixed, tell you plainly when a furnace is done, and never sell you heat you do not need.
When your furnace quits in a Lansing winter, you need two things fast: a real diagnosis and a straight answer about what it costs to fix. That is the whole job here. We find the actual problem, show it to you, quote a flat price before we touch a wrench, and repair what can be repaired. When a furnace is genuinely done, we tell you plainly and help you plan a replacement on your terms, not in a panic on the coldest night of the year.
No-heat calls go to the front of the line, and most get a truck the same day.
One clear number quoted before the work starts. No commission, no meter.
We fix what can be fixed and only recommend replacement when it is truly the right call.
A furnace rarely fails at a convenient hour. It goes out overnight, on a holiday, during the first hard freeze when every honest shop in town is already booked. We built our service side around that reality. When you call Kestler with no heat, a real person answers, gets the details, and tells you honestly when we can be there. We do not promise a window we cannot keep just to get you off the phone.
What we repair
Most furnace trouble comes down to a handful of parts and a few common failures, and the great majority of them are a repair, not a replacement. We work on gas furnaces of every age and brand found in Lansing homes, from the workhorse units in older south-side houses to the high-efficiency systems in newer builds out toward DeWitt.
- No heat at all: failed igniter, bad flame sensor, tripped safety, or a pilot that will not stay lit
- A furnace blowing cold air, which is often a thermostat setting, a clogged filter, or a lockout doing its job
- Short-cycling, where the furnace kicks on and off without ever settling into a run
- Loud booms, rattles, or grinding on startup that point to ignition delay or a worn blower
- A furnace that runs constantly and still cannot keep the house warm
- Rising bills or uneven heat from room to room
If your furnace is running but the air feels cool, that is a specific problem with a short list of causes, and we walk through them in our guide on why a furnace blows cold air. If it keeps starting and stopping, that is usually airflow or a safety tripping, which we cover in our piece on furnace short-cycling.
How we diagnose
Our technician finds the real cause before quoting a fix, and then shows it to you. That sounds obvious, but it is not how every company works. A dirty flame sensor and a cracked heat exchanger both stop a furnace, and one is a cheap clean while the other is a safety issue that ends a furnace's life. We do not guess and we do not upsell the scary version. You see the actual problem, in plain words, and the decision stays yours.
Repair or replace, honestly
The hardest conversation in this trade is the one where a repair no longer makes sense. We do not dodge it, and we do not rush it the other way either. The right answer depends on the age of the furnace, the cost of the repair in front of you, and how many winters the unit likely has left. A small fix on a ten-year-old furnace is an easy yes. A major repair on a twenty-year-old unit usually is not. We lay out the math for your specific situation, and our full guide on how long a furnace lasts in Michigan explains how we think about it.
When replacement is the right move, our comfort advisor walks your house, runs a proper load calculation, and sizes the new furnace to your actual home rather than matching whatever was there before. An oversized furnace short-cycles and wears out early, so getting the size right is not a detail, it is the whole job. And because our techs are not on commission, nobody here has a reason to steer you toward a bigger unit than you need.
Why homeowners stay with us
Kestler has repaired furnaces in this town since 1987, and a lot of our work is for families whose parents were customers first. The reason is simple: we quote flat prices before the work, we fix before we replace, and we tell people the truth even when it costs us the sale. If you would rather never think about a surprise breakdown again, our Comfort Club keeps your furnace tuned on schedule and moves you to the front of the line when something does go wrong.
Common questions
What homeowners ask
How fast can you come out for a no-heat call?
A no-heat emergency in a Michigan winter goes straight to the front of our schedule, and in most cases we can get a truck to you the same day. During a hard cold snap when everyone loses heat at once, we are honest about the wait rather than overpromising. Our office manager will tell you exactly where you stand.
Will you try to sell me a new furnace?
No. We repair before we replace, and our technicians are not paid on commission, so nobody profits by pushing you toward a new unit. When a furnace genuinely needs replacing we will show you why in plain terms, but we will never manufacture a reason to sell you one.
Do you work on all furnace brands?
Yes. We service gas furnaces of every age and brand common in Lansing homes, from older standard-efficiency units to modern high-efficiency systems. If we run into something unusual, we will tell you honestly what parts availability looks like before you commit to a repair.
How do I know if I should repair or replace my furnace?
It comes down to the furnace's age, the cost of the repair in front of you, and how many winters it has left. A small repair on a newer furnace is usually worth it, while a major repair on a furnace near the end of its life often is not. We give you the honest math for your exact situation rather than a canned answer.
