QUICK ANSWER

Common air-conditioning problems include failed capacitors, fan-motor issues, electrical faults, refrigerant leaks and blocked condensate drains. Our technician tests the system, explains the findings and provides the repair price for your approval before any repair begins.

What an air-conditioning repair visit includes

Your technician begins with the reported problem, then checks the related components to identify the cause and any conditions that may have contributed to the failure.

  • Thermostat operation and system controls
  • Electrical voltage, amp draw and safety components
  • Capacitors, contactors, fan motors and compressor operation
  • Filter condition, airflow, coils and condensate drainage
  • Refrigerant pressures and temperatures when required
  • Findings, readings and recommended repairs documented in your service file

Once the problem is identified, the technician explains the findings and provides the repair price for your approval.

What to expect from start to finish

  1. Call and schedule

    Our office team records the symptoms, equipment information and urgency, then confirms the service details and schedules the appropriate technician.

  2. System diagnosis

    The technician tests the equipment, records the relevant readings and explains the cause of the problem in clear terms.

  3. Your approval first

    We explain the recommended work and pricing for your approval before repairs begin. The pricing method depends on the nature of the job and is confirmed with you. If replacement makes more sense than repair, we say so.

  4. Repair and documentation

    When the required parts are available, the repair is completed during the same visit. The work performed, parts used and final operating results are added to your service history.
