The short answer

Air Conditioning Repair in Greenwich typically runs $300–$750 — the $95 diagnostic is credited toward the repair. Most jobs finish same-day in one visit with genuine OEM parts, backed by a 1-Year Parts & Labor Warranty. Call (475) 281-3784.

Air conditioning failures during hot weather require immediate attention. Greenwich summers bring heat and humidity that make functioning AC essential for comfort and health. Our HVAC technicians diagnose and repair all cooling system types including central air conditioning, ductless mini-splits, and heat pumps operating in cooling mode. We address refrigerant issues, compressor problems, electrical failures, and airflow restrictions. Emergency service is available for AC failures during heat events.

AC diagnosis begins with temperature measurement at supply and return vents. Refrigerant pressures are tested where system type allows. Compressor operation is evaluated including amp draw. Electrical components are tested. Condenser and evaporator coils are inspected for cleanliness. Airflow is measured. Thermostat function is verified. This systematic approach identifies specific failure causes.

Greenwich's coastal location brings humidity that stresses AC systems. Salt air affects outdoor condenser units, requiring regular cleaning. Annual coil cleaning helps maintain efficiency in coastal environments.

Answers

Frequently asked questions

Why is my AC running but not cooling?

Running without cooling typically indicates refrigerant issues, failed compressors, dirty coils, or airflow restrictions. Low refrigerant requires leak repair and recharging. Dirty coils reduce heat transfer. We diagnose the specific cause.

Why is ice forming on my AC unit?

Ice formation results from restricted airflow or low refrigerant. Dirty filters are the most common cause. Low refrigerant causes evaporator temperatures to drop below freezing. We identify and address the root cause.

How often should AC units be serviced?

Annual professional maintenance before cooling season extends system life, maintains efficiency, and prevents breakdowns. Homeowners should replace filters monthly during heavy use periods.

“Lower zone climbed six degrees overnight. New zone sensor, door gasket reseated, and it holds steady now. My one complaint is that the sensor took eight days to come in.”
— Priya S.
“Compressor never shut off and the interior sat around 45 degrees. The condenser was packed with dust and dog hair, and the fan motor had quit. He cleaned the coil, fitted a new motor, and it cycles normally.”
— Rafael N., Greenwich, CT · July 2026
“The oven stalled below 300 no matter what I set it to. He measured igniter draw, found it weak, and changed the igniter and the safety valve as a pair. Roasting temperatures have read true ever since.”
— Adele F., Byram, CT · May 2026
“Cakes came out scorched along the right wall of the lower oven and pale on the left. One convection motor was turning slowly, so he replaced it and then read temperatures at three rack heights. Baking is even again. Scheduling did take two calls to pin down.”
— Hugh B., Mid-Country, CT · April 2026
