Signs Your Furnace Needs Repair

Call us if you notice any of these:

No heat, or the furnace won't turn on. Often a failed igniter, flame sensor, control board or thermostat.
Furnace blowing cold air. Common causes are a dirty flame sensor, a tripped limit switch or a pilot problem.
Short cycling. A furnace that turns on and off every few minutes usually points to overheating, a clogged filter or an oversized system.
Uneven heat from room to room. Rooms more than 4 to 5 degrees apart usually mean airflow or ductwork problems.
Strange noises. Banging, squealing or grinding typically means a failing blower motor, bearings or a delayed ignition.
Rising gas bills. An efficiency drop with no change in use means something inside is wearing out.
Carbon monoxide alarm or a gas smell. Leave the house and call 911 and your gas utility first, then call us.

Our Furnace Repair Process

Diagnose. Your technician runs a full system check, including gas pressure, temperature rise, electrical draw and a carbon monoxide test.
Quote. You get a flat, by-the-job price for the repair before we start. We price by the job, not the hour.

Test. We run the system through a full heating cycle and recheck safety controls before we leave.

Repair or Replace? A Straight Answer

We'll tell you honestly when a repair makes sense and when it doesn't. As a rule of thumb, a furnace under 10 years old with one failed part is almost always worth repairing. A furnace over 15 years old that needs a major part, such as a heat exchanger or blower motor, is often better replaced. If replacement makes sense, we'll show you the numbers side by side and you decide.

Milwaukee Furnace Repair FAQs

What is the $5,000 rule for furnaces? Multiply your furnace's age by the repair cost. If the result is over $5,000, replacement is usually the better value. For example, a $400 repair on a 14-year-old furnace equals $5,600, so it's worth pricing a new unit.

What is the most expensive part to fix on a furnace? The heat exchanger. A cracked heat exchanger can leak carbon monoxide, and replacing it often costs close to a new furnace, so replacement is usually the better choice.

How long does a furnace last in Wisconsin? Most gas furnaces last 15 to 20 years with yearly maintenance. Long Wisconsin heating seasons put more hours on a furnace, so annual tune-ups matter more here.

Do you offer 24/7 emergency furnace repair? Yes. Call any time, day or night.

Why is my furnace blowing cold air? The most common causes are a dirty flame sensor, a tripped high-limit switch from a clogged filter, or a thermostat set to "on" instead of "auto." If a filter change doesn't fix it, call us.
