In DeKalb County we replace and repair furnaces and central air in Auburn, Garrett, Butler and Waterloo, and service propane furnaces on farm properties along the I-69 corridor. Older town houses bring duct and venting problems, south Auburn subdivisions bring first-time equipment replacements, and farmhouses bring propane and outbuilding heat. Landcons answers the phone 24/7.
Head north from Allen County on I-69 and you reach DeKalb County in a few minutes. Auburn is the county seat, known to car people for the Auburn Cord Duesenberg Automobile Museum, and its older streets around the courthouse hold houses that have been heated by coal, oil, gas and everything in between. Garrett, Butler and Waterloo have their own town centers with similar early housing.
Out between the towns, the county turns to farmland, and farmhouses there commonly heat with propane. Closer to the interstate, Auburn's south side has filled in with newer homes over the past few decades. That spread means our technicians might replace a builder-grade furnace in the morning and chase a propane regulator problem on a farm lane in the afternoon.
From courthouse-square houses to south Auburn subdivisions

In the older town centers, many homes have been through several heating conversions. We find furnaces vented into masonry chimneys that were built for coal, with no liner and with flue tiles that have cracked over time. When an owner upgrades to a 95 percent furnace, the old chimney can end up serving a water heater alone, and that often leads to poor draft and condensation unless the chimney is relined or the water heater is replaced with a power-vent model.
The newer homes on Auburn's south side tend to have their first or second set of equipment. Those builder-grade furnaces and condensers are now reaching the age where repairs start stacking up: capacitors, igniters, inducer motors, then a refrigerant leak in a coil. That is when owners ask whether to keep fixing or replace both pieces together, and we lay out the numbers honestly for each case.
Typical DeKalb County visits, town and country
Here is what we get called about most often north of the Allen County line.
Repair or replace a 15-year-old system
Subdivision homes in Auburn often hit this question when a coil leaks or a heat exchanger shows wear. We price both options so you can compare a repair against a matched furnace and AC replacement.
Chimney venting after a furnace upgrade
An orphaned water heater left alone in an old masonry chimney can backdraft. We test draft and recommend a liner or power-vent water heater if needed.
Propane heat on farm properties
Farmhouses on propane need correct gas pressures and clean burners to avoid sooting. We service propane furnaces, water heaters and shop heaters on the same visit when we can.
Upstairs comfort in older Garrett and Butler homes
Early 1900s houses often have weak duct runs to the second floor. A return air path, duct changes or a ductless head usually solves the hot and cold rooms.
Why DeKalb County winters are hard on aging equipment
Wind across open farmland north of Fort Wayne makes a cold night feel colder to a house, and older homes in Auburn and Garrett lose heat fast through original windows. A furnace that was barely keeping up in a mild winter can fall behind during a run of single-digit nights, and that is often when a weak inducer or cracked igniter finally quits. A fall tune-up catches most of those parts before they fail.
Replacement timing matters too. If your system is old enough that you are thinking about it, calling in late spring or early fall gives you more choice in equipment and scheduling than waiting until a January breakdown forces the decision. Ask us about current Indiana Michigan Power and NIPSCO rebate programs when you call.

DeKalb County questions
Do you replace furnaces and AC units in Auburn and the rest of DeKalb County?
Yes. We install furnaces, central air, heat pumps and matched systems throughout DeKalb County, including Auburn, Garrett, Butler and Waterloo. Each job starts with a load calculation so the new equipment fits the house, not just the old unit's size. We also handle permits, venting changes and gas line work.
What does a furnace and AC replacement cost in DeKalb County?
Replacing both a gas furnace and central air together in a typical DeKalb County home runs about $7,485 to $14,865, depending on efficiency, size, duct changes and venting. Propane systems cost about the same for equipment. We give you the real price after measuring the house and checking the existing setup.
Is my DeKalb County farmhouse a good fit for a heat pump?
Often yes, especially paired with your propane furnace as a dual fuel system. The heat pump handles mild weather cheaply and the propane furnace takes over in deep cold. Whether it pays depends on your propane price, electric rate and how tight the house is, which we look at on a visit.
Can you come to Butler or Waterloo for an emergency AC or heat call?
Yes. Landcons answers the phone 24/7, and we dispatch to the far ends of DeKalb County, including Butler and Waterloo. We give you an honest arrival time when you call and talk through anything you can safely check while you wait.
