A furnace that quits in Wausau is a different problem than one that quits in Milwaukee. With January lows that regularly fall below zero, pipes in a home without heat can start freezing within hours. Southport repairs gas, propane and electric furnaces, boilers and heat pumps across Wausau, Weston and Schofield, with NATE-certified technicians who explain the problem and the price before touching anything.

When to Call for Heating Repair
Heating systems usually show strain before they stop completely. Booking a repair at the first sign of trouble is cheaper than a no-heat visit during a cold snap.
- The furnace runs but the house stays cold, which can mean a dirty filter, a failing blower or a heat exchanger that is not transferring heat.
- The igniter clicks but the burners never light, a common symptom of a bad flame sensor, gas valve or pressure switch.
- Water pools around a high-efficiency furnace, usually from a cracked or frozen condensate line.
- Some radiators heat, and others do not, pointing to trapped air, a stuck zone valve or a weak circulator on a boiler system.
How We Handle Heating Repairs
Every call starts with a full diagnosis. Our technicians watch the system go through a heating cycle, then test ignition, flame quality, gas pressure, electrical components, airflow and venting. That process finds the root cause instead of the first failed part, so the same problem does not come back two weeks later.
You get a written explanation and an upfront price before any repair starts. If the system is old enough that replacement deserves a look, the technician will tell you and give you the repair cost anyway, so the decision stays yours.
Southport’s trucks work like a warehouse on wheels. They carry the igniters, flame sensors, capacitors, inducer and blower motors, circuit boards and pressure switches that fail most often in Wisconsin winters. That stock lets our team finish most repairs in one trip instead of leaving you without heat while parts are ordered.
Many homes outside Wausau city limits run on propane instead of natural gas, and our technicians service both, including the orifices and gas pressure settings that differ between the two fuels. We also work on hot water boilers and on heat pumps that rely on a furnace or electric strips for backup during the coldest weeks.
After the repair, the system is run through a complete cycle and checked for safe operation, and repairs are covered for 30 days on parts and labor.
Furnace Repair
Furnace repairs include igniters, flame sensors, inducer motors, blower motors, limit switches and control boards. If we find a cracked heat exchanger, we shut the furnace down and show you the damage.
Boiler Repair
We repair circulators, zone valves, expansion tanks, low-water cutoffs, and relief valves, and we purge air from the loop so every zone heats.
Heat Pump Repair
Heat pump repairs cover defrost controls, reversing valves, refrigerant leaks and auxiliary heat. Backup heat gets extra attention in Wausau, since it carries the load on the coldest nights.
