A closer look
Turn a symptom into a clear explanation
Similar comfort complaints can have different causes. Diagnosis connects what you observe at the thermostat and vents with the condition of the equipment, its controls and the way air moves through the house.
The checks depend on the complaint and may include operating temperatures, airflow, drainage and electrical measurements. Findings guide the repair recommendation; parts should not be changed simply to see what happens.
What a diagnostic looks at
- Electrical components, controls and thermostat
- Refrigerant-side operation and coil condition
- Airflow, filters and duct restrictions
- Condensate drainage and safety switches
- Overall system performance and efficiency
When a diagnostic is the right first step
If your home never quite gets comfortable, your bills keep rising, the system makes new noises, or it cycles on and off, a diagnostic is a better starting point than replacing parts one at a time.
