Experienced HVAC Services in San Antonio, TX 78247 - Alamo Heating & Air Conditioning

Yes, a non-functioning indoor fan is a classic sign of a blower motor failure, a common issue we see in San Antonio due to constant system use. The motor can fail from age, overheating, or electrical issues. Our technicians will test the motor, capacitor, and associated wiring. We typically carry common replacement motors on our trucks, allowing for a quick repair to restore your cooling and airflow.

Frequent thermostat errors or a loss of connection to your HVAC system are often caused by wiring problems. The vibration from system operation, heat in the attic where wires are run, or initial improper installation can loosen or damage the low-voltage wires. Our experts will trace the thermostat wiring, check terminals at both the thermostat and the air handler, and repair or replace any faulty wiring to ensure reliable communication and control.

Our diagnostic service is a thorough inspection to pinpoint the root cause of your system's failure. For common issues like no cooling or fan problems, we'll check electrical components (capacitors, contactors), test the blower motor and its relay, inspect thermostat wiring integrity, measure refrigerant levels, and assess system airflow. You'll receive a clear, honest explanation of the problem, repair options, and upfront pricing before any work begins.
