In Whitley County we service geothermal heat pumps, propane furnaces and central air for homes in Columbia City, Churubusco, South Whitley and the lake and farm properties between them. Common calls include ground loop pressure faults, propane furnace lockouts, lake home humidity and aging AC. Our phone is answered 24/7 every day, holidays included.
Whitley County sits just across the Allen County line to the west, with Columbia City as its seat and Churubusco and South Whitley as the other main towns. Outside them, the county is a patchwork of farmland and small lakes. That mix means a heating visit here could be a gas furnace near the courthouse square, a propane furnace on a gravel lane, or a geothermal unit in a lake home basement.
Geothermal deserves its own mention. Rural lots in this county often have the space for a horizontal ground loop, and owners who got tired of propane delivery bills have been making the switch for years. Landcons services these systems along with the propane and gas equipment that still heats most homes, so you do not need one company for the loop and another for the furnace.
What we find inside Whitley County lake and country homes

Lake homes are their own category. Many started as summer places and were added onto over the years, so the ductwork can be a patchwork of old and new runs with the furnace in a crawlspace or a utility closet. Humidity is the big summer issue. A house close to water that is closed up during the week can reach high indoor humidity quickly, and the AC alone may not pull enough moisture out unless it runs long cycles.
Farm properties lean on propane for the furnace, water heater and often a shop heater, with long buried lines from a single tank. Geothermal homes use a water-to-air heat pump connected to loops in the ground, with a flow center pumping fluid through them. When a geothermal system has trouble, the cause is usually on the loop side: low pressure, air in the lines, a weak pump or antifreeze that has drifted. We check those before ever condemning a compressor.
Calls we get most from Columbia City, Churubusco and the lakes
These patterns repeat across Whitley County every year.
Geothermal unit tripping in deep cold
Low entering water temperature or low loop pressure can lock out a ground source heat pump on the coldest nights. We test loop pressure, flow and antifreeze concentration, then check the refrigerant side.
Propane furnace sooting or short cycling
A furnace set up for natural gas but running on propane, or with a dirty burner, can leave soot and trip safeties. We confirm the conversion and set the gas pressure correctly.
Damp, musty lake homes
A whole-home dehumidifier holds humidity near 50 percent even when the house sits closed. That protects drywall, furniture and the HVAC system itself.
AC that cannot keep up in July
Older condensers on lake homes often run with dirty coils, cottonwood buildup and low charge. A cleaning and charge check is usually the first step before any replacement talk.
Shop and pole barn heat
Vented propane unit heaters for barns and workshops are common requests. We size the heater, run the gas line and set up venting to code.
Ground loops, propane tanks and long drives on US 30
Columbia City is about 20 miles from our downtown office, and we cover the whole county from there, including the smaller lake roads. Rural calls work best when you can tell us the fuel type and the system brand on the phone, so we bring the right parts. WaterFurnace is based in Fort Wayne, which keeps geothermal parts and technical support close at hand for Whitley County owners.
If you are weighing geothermal against a new propane furnace, we will compare the install cost, your current fuel spending and the condition of your ductwork. Indiana Michigan Power runs rebate programs that change from year to year, and we will tell you what is current.

Whitley County questions
Do you repair geothermal heat pumps in Whitley County?
Yes. We diagnose and repair geothermal systems throughout Whitley County, including loop pressure checks, flow center pump replacement, antifreeze testing and water-to-air heat pump repairs. Most problems we find are on the loop or pump side and cost far less than the compressor failure owners fear.
What does geothermal installation cost on a Whitley County property?
A full geothermal system with a new horizontal loop typically runs about $21,485 to $38,965 in Whitley County, depending on house size, loop type and ductwork. Replacing just the indoor heat pump on an existing loop costs much less. We give the real price after a site visit and load calculation.
Can you service propane furnaces near Churubusco and South Whitley?
We do. Propane furnaces, water heaters and garage heaters are a big part of our Whitley County work. We check tank-side regulator issues, appliance gas pressure, burners and venting, and we handle conversions when an appliance needs to switch between propane and natural gas.
How do I keep a Whitley County lake home from getting musty?
Set the thermostat to cool rather than turning the system off, and add a whole-home dehumidifier set around 50 percent. That keeps moisture down even when no one is home during the week. We can also check whether your AC is oversized, which makes it cool fast without removing enough moisture.
