✅ San Jose — Furnace Repair (Carrier Model: 58MCB060-12)

A customer reached out with a short but urgent message: “the furnace isn’t working.”
Brand — Carrier, model 58MCB060-12. We arrived quickly and performed a full diagnosis.
Reminder: diagnosis is FREE with repair.

✅ What did we find?

The problem was a clogged condensate drainage system. Water backed up and filled the induction motor, which caused the entire furnace to shut down.
This type of issue is especially common in homes where the furnace and AC share a single drainage line. Over time, dust, debris, mold — or even insects — can cause a blockage. And the worst part? You won’t know anything’s wrong until the system stops working altogether.

✅ What did we do?

  • Safely removed the water from the induction motor
  • Completely cleaned the drainage system for both the furnace and AC
  • Tested the unit after restart — everything is working perfectly again

✅ Why call a technician?

It might seem like a simple issue, but water damage can destroy control boards, motors, or cause internal corrosion.
DIY solutions like blowing air through the pipe or flushing it with vinegar often don’t solve the real problem — and sometimes make it worse.
Calling a professional means proper tools, fast service, and a job done right — with a warranty.

✅ Result

The furnace was repaired without replacing any expensive components. Everything was fixed in one visit. The home is warm again, and the customer is happy.

✅ Pro Tip from Our Technicians

If your AC and furnace share a drain line, schedule a professional drainage cleaning at least once a year.
It’s a small step that prevents major headaches and unexpected shutdowns.
