HVAC System Diagnostic

Garcia Construction Inc’s expert technicians perform a 15-point diagnostic examination to pinpoint current or upcoming issues within your system. Some of the key elements on our checklist are: fuses, disconnect box, contactor, capacitors, condenser fan motor, blower motor, and thermostat. Then we proceed to check electrical components for the appropriate voltage and ampere draw. Next, we inspect the filter, evaporator coil and condenser coil for cleanliness, or lack thereof. Then, we take a reading of system static pressure to determine proper airflow and test the refrigerant circuit to ensure correct refrigerant levels. Finally, we examine the overall installation to ensure the work was done to code and without errors. After our diagnostic has been completed, we report our findings to the Owner along with a reasonable price for repairs. This HVAC system diagnostic is a wise investment which proves to be very effective for the Owner because preventative maintenance counters unexpected down time along with costly repairs in the future.

Common HVAC Issues


HVAC systems have a few motors, one to run the compressor, one to run the outdoor fan, and another to run the indoor blower. If any of these motors malfunction the system will not operate properly.


Capacitors give motors a boost of energy to assist them in turning over. HVAC systems have several capacitors and each one can and will eventually fail. A weak or failed capacitor will prevent a motor from starting. All of a motors must be operating in order for an HVAC system to function properly.

Electrical components

HVAC systems utilize various electrical components and electronic circuitry to control their numerous functions. Some examples are contactors, relays, switches, circuit boards, and defrost boards. While the basic components can turn a system on and off, complex components often work in tandem with multiple-speed blowers, reversing valves, emergency heating elements, and more. It is imperative for these electrical components to function properly as a slight malfunction can render a unit inoperable.

Refrigerant system

HVAC systems operate with refrigerant in a closed-loop system. In theory, the amount of refrigerant in the system should remain constant for the life of the system. However, if a leak develops somewhere in the refrigerant loop, refrigerant will be lost and the system will transfer heat less effectively. Finding and repairing the leak, and replacing lost refrigerant is essential to bring the system back to its full operating potential, thereby saving you money on electric bills.
