Common AC Repairs We Handle in Monroe, WI

Most air conditioning failures trace back to a handful of components. Our technicians diagnose the full system first, identify the cause, and walk you through the repair and cost before any work starts.

Capacitor and Contactor Failure

A failed capacitor is one of the most common reasons an AC unit won't start or runs but doesn't cool. Contactors wear over time and can prevent the compressor or fan from engaging. Both are straightforward repairs when caught early.

Refrigerant Issues

Low refrigerant is a symptom, not a cause — it means there's a leak somewhere in the system. We locate and repair the leak, then recharge the system to manufacturer spec. Simply adding refrigerant without addressing the leak is a short-term fix that compounds the problem.

Frozen Evaporator Coils

Ice on your indoor unit typically points to restricted airflow or low refrigerant. A frozen coil prevents the system from cooling and can damage the compressor if left running. We identify the underlying cause rather than treating the symptom.

Dirty Condenser Coils

An outdoor unit clogged with debris can't release heat efficiently, forcing the system to work harder and cool less. Annual maintenance prevents this — but if it's already affecting performance, a cleaning and system check resolves it.

Thermostat and Electrical Failures

Sometimes the air conditioner is functional and the problem is a thermostat that's lost its calibration or a wiring fault upstream. We trace the failure to its source rather than replacing components based on guesswork.

What an AC Service Call Looks Like

When a Lanz technician arrives, they assess the full system — not just the component that appears to have failed. You get a clear explanation of what's wrong and what the repair will cost before any work begins. No surprise invoice at the end.

If the repair cost approaches what a replacement would run, we'll tell you that too. Free estimates on new Lennox systems give you a real comparison — not a pressure decision in the middle of a heat wave.

AC Repair or AC Replacement — How Do You Know Which One You Need?

Age, repair history, and the nature of the failure all factor into whether a repair makes sense. A unit under ten years old with a first-time component failure is usually worth repairing. A system pushing fifteen years with a compressor problem is often a closer call. We give you an honest assessment of both options — including a free estimate on a new Lennox system if replacement is the better path — with no obligation to decide on the spot.
