Comprehensive diagnostic and repair services for split-system, package unit, and whole-home central air conditioning systems.

Common Symptoms

• Inconsistent cooling across different rooms or floors
• System running constantly without reaching thermostat setpoint
• Airflow from supply registers feels weak or lukewarm
• Unusual humming, buzzing, or grinding sounds during operation
• Noticeable spikes in monthly electric bills without weather changes

Possible Causes

• Failed dual-run capacitor or pitted electrical contactor
• Restricted airflow from heavily clogged media filters or closed dampers
• Refrigerant undercharge resulting from pinhole coil leaks
• Failing indoor blower motor or faulty motor capacitor
• Thermostat communication error or sub-base wiring corrosion

Safe Homeowner Checks

• Verify that the thermostat is switched to "COOL" mode with fan set to "AUTO"
• Inspect and replace dirty air filters with the correct MERV rating
• Ensure all indoor supply vents and return grilles are completely unblocked by furniture or drapes
• Check the main electrical panel for tripped circuit breakers dedicated to AC and Air Handler
• Clear away leaves, tall grass, and debris from around the outdoor condenser unit (minimum 2 feet clearance)

Frequently Asked Questions

How long does a central air conditioner typically last in the United States?

Central air conditioning systems typically last 12 to 17 years depending on regional climate, annual run hours, and routine maintenance. In high-humidity coastal or extreme desert environments, operating lifespan often averages closer to 10 to 12 years due to heavy duty cycles and environmental exposure.

What is a normal temperature drop between return and supply air?

A properly functioning central air conditioner should produce a temperature split (Delta-T) between 16°F and 22°F. If the difference is below 14°F, the system may suffer from low refrigerant charge, poor airflow, or an underperforming compressor.

Should I shut my AC off if it is running continuously but not cooling?

Yes. If your AC is running non-stop without lowering indoor temperatures, turn the system to "OFF" at the thermostat. Continuous running under distress can overheat the compressor motor windings and cause catastrophic mechanical seizure.
