Common questions
The 'AC rule' often refers to a guideline suggesting that if a repair exceeds a certain cost threshold, replacement might be more economical. For California homeowners, this threshold is not a fixed dollar amount. Factors like the age of your system, its efficiency, and potential future repairs influence this decision. We provide clear assessments to guide you.
Why is my AC running but not cooling?
Several issues can cause your AC to run without cooling in California homes. These include low refrigerant levels, a faulty compressor, or a dirty evaporator coil. Blocked airflow from clogged filters or vents also impedes cooling. Our technicians diagnose these problems efficiently to restore comfort to your San Diego residence.
What does a typical AC repair cost?
The cost of AC repair in California depends on the complexity of the issue, the parts needed, and labor involved. Simple fixes like thermostat adjustments or refrigerant top-offs are generally less expensive than major component replacements.

What is the 3 minute rule for AC?
The '3-minute rule' for AC systems advises against cycling the unit on and off rapidly. Allowing at least three minutes between cycles prevents potential damage to the compressor. Frequent short cycles can lead to premature wear and costly repairs for your San Jose home's HVAC.
What are common furnace issues in California?
Common furnace issues in California include ignitor failures, thermostat malfunctions, and pilot light problems. Clogged filters and dirty burners also reduce efficiency. Our technicians address these problems promptly, ensuring reliable heating for your Sacramento home during cooler months.
