We fix and replace natural gas and propane furnaces in and around Decatur, repair and install central air, service water heaters and run gas lines for garages and shops. The steady calls are furnace ignition faults, worn blower motors and summer AC breakdowns. Decatur is about 22 miles southeast of our office on US 27, and we answer 24/7.
Decatur is the Adams County seat, about 22 miles southeast of downtown Fort Wayne on US 27, with the St. Marys River running through town. That same river flows north to our side of the region, past our office at 121 W Wayne Street, before it meets the St. Joseph and forms the Maumee. With around 9,900 people, Decatur is a compact town, and once you leave its edges the land opens into farmland where gas lines thin out and propane tanks sit beside most houses.
That split shapes the work. In town we mostly see gas furnaces paired with split system air conditioners. In the countryside, a large Amish community lives in the south of the county, and many of the non-Amish rural homes we visit heat with propane or rely on outbuilding heaters for shops and barns. Call (260) 283-0173 whenever something stops working; our line is answered 24/7.
How Decatur and Adams County homes are heated

Houses inside Decatur run mostly on natural gas, with the furnace in a basement or utility room and a condenser outside. The age range is wide, so we see everything from a 1960s furnace someone kept running far too long to a two-stage unit installed a few years ago. Older homes near the river can have damp basements, which is hard on furnace cabinets, burner assemblies and the bottoms of steel ducts. Rust at the base of a furnace is worth having looked at, because it can point to condensate leaks or a humid space that will shorten the life of the next unit too.
Rural homes add propane to the mix. A propane furnace needs its gas valve and orifices set for propane, and a regulator at the tank and at the house to hold the right pressure. When those regulators age or freeze, the furnace may light weakly or lock out. Many properties also have a shop, garage or pole barn, and adding a vented unit heater out there means sizing a gas line from the tank or the house supply properly.
Typical reasons Decatur families call us
These come up week after week, with heating calls peaking from November through February.
Furnace lights, then shuts off
A furnace that fires for a few seconds and quits usually has a dirty flame sensor or a weak flame from low gas pressure. On propane homes we check the regulator too, since a frozen or failing regulator causes the same symptom.
Blower motor failing on an older furnace
A blower that hums, runs slow or smells hot is near the end of its life. We test the motor and capacitor and price a replacement motor against the age of the furnace.
Shop and pole barn heaters
Rural customers often want heat in a garage or barn. We size a vented gas unit heater, run the gas line and vent it correctly through the wall or roof.
Summer AC breakdowns
Most no-cooling calls in Decatur are electrical parts or a clogged outdoor coil, both fixable the same day. Older R-22 units with leaks are where we start discussing replacement.
Water heaters near the end
A water heater leaking from the bottom of the tank needs replacing, not repairing. We install gas, propane and electric tanks and check the venting on every one.
Reaching Decatur from downtown, day or night
US 27 makes the 22-mile trip to Decatur straightforward. We answer 24/7, so the first thing you get is a person, not a recording. The questions we ask on that call, such as fuel type, furnace age and what the thermostat shows, let the technician pack the right flame sensor, igniter, regulator or capacitor before leaving.
If your propane furnace stops on a very cold night, check the tank gauge and look for frost on the regulator. Never try to adjust the regulator yourself; that is a job for us or your propane supplier.
Decatur questions
Do you work on propane furnaces near Decatur?
Yes. Propane heat is common outside Decatur, and we service those furnaces regularly. We check the gas pressure at the furnace, look at the regulators, and clean or replace the ignition parts that fail most often. If the supply side is the problem, we tell you, so your propane company can handle the tank while we handle the furnace.
Can Landcons put a heater in my Decatur area pole barn or garage?
We can. Vented gas unit heaters are the usual choice for garages, shops and pole barns. We size the heater for the space and insulation, run the gas line from your house supply or propane tank, and vent it through the wall or roof. Typical installs run $1,895 to $4,485 depending on heater size and gas line length.
How long does a furnace replacement take in Decatur?
Most straightforward furnace replacements are finished in one day. Jobs that need new venting, a gas line change or duct modifications to fit the new cabinet can run into a second day. We explain the plan and the timing before the work starts, and we make sure the house has heat before we leave whenever possible.
Will someone answer if I call about Decatur heat late at night?
Yes. Our phone at (260) 283-0173 is answered 24/7, including weekends and holidays. Decatur is about 22 miles from our downtown office, so we give you a realistic arrival estimate and talk you through safe checks while the technician drives down US 27.
