Furnace Repair in Wausau

A working heater is absolutely critical for comfort and safety during the freezing Wisconsin winters. If your furnace or other heater isn’t doing its job, be sure to call Frasier’s to schedule your appointment for furnace repair in Wausau. From mechanical repairs to dirty furnace filter replacements, we’ll get your heater working in no time.

Our Wausau furnace repair team can handle all sorts of common heating issues, including:

  • Pilot light won’t stay lit: If you have a gas furnace, a malfunctioning pilot light means that your furnace won’t work. Usually, pilot light issues signal a problem with the thermocouple.
  • Furnace smells bad: Is your gas furnace emitting a rotten egg smell? Are you smelling burning plastic or ozone? Any odd smell coming from your furnace should be treated as as emergency. Turn off your system and call for furnace repairs immediately.
  • Furnace is blowing cold air: If your furnace turns on but isn’t blowing warm air, you may have a dirty air filter or faulty burners. You should also check your thermostat to make sure it is set to “AUTO” instead of “ON.”
  • Furnace is making unusual sounds: Do you hear a booming, banging, rumbling, clicking, buzzing, whistling, or any other weird noise coming from your furnace? Strange sounds have a number of causes, but all should be investigated by a furnace repair professional.
  • There’s rust on your furnace: Rust could indicate combustion gas/exhaust problems. If you have a gas furnace, this evidence of the presence of excess carbon monoxide poses a safety hazard, so call for repairs as soon as possible.

To keep your heater in good condition and extend its lifespan, be sure to schedule a furnace maintenance appointment at least annually. Periodic maintenance is a simple way to get the most out of your heater and protect your investment. Regular maintenance can also reduce the chances that your heater will completely break down when you need it most.

Heating & Air Conditioning Replacements & New Installations

At Frasier’s, we always strive to repair HVAC systems when it makes sense to do so. However, if your older system is beyond repair or if it would simply make more financial sense to forego repairs in favor of a replacement, we’ll guide you through your options for selecting a new system. We install air conditioners and furnaces from trusted brands and happily offer financing options to help make your purchase more affordable!
