The MDTECH 4-Step AC Unit Repair Process

We have streamlined our service to get your cool air flowing quickly and reliably.

1. Rapid Contact & Scheduling

Call our local Southern California office, and we will schedule an appointment immediately. We prioritize emergency repairs, arriving promptly with fully stocked service vehicles to reduce diagnostic and repair time.

2. Precision Inspection & Diagnosis

Our technicians use advanced tools to perform a complete system check, looking for both simple and complex failures. We commonly diagnose and repair issues such as:

• Failed Capacitors or Contactors: The most common electrical failures that stop the unit from starting or running correctly.

• Refrigerant Leaks: We locate, repair, and seal leaks before adding the correct refrigerant charge, complying with all EPA regulations.

• Blower Motor Issues: Diagnosing electrical shorts, bad bearings, or failed belts causing poor airflow.

• Clogged Condensate Drains: Clearing clogs caused by sludge and algae that trigger safety shutdowns and cause water damage.

3. Clear Quote & Guaranteed Repair

Before any work begins, we provide a clear, written quote detailing the required repairs and costs. Once approved, we use only high-quality, authorized replacement parts. Our goal is to fix it right the first time, extending the life of your existing AC unit.

4. Final Testing & Performance Verification

After the repair is complete, we perform a final series of checks, including measuring the temperature differential ($\Delta T$) and amperage draw, to confirm the AC unit is operating at its maximum specified efficiency and cooling capacity.
