OUR HVAC WORK IN THE BAY AREA
EFFICIENCY DESIGNED FOR EVERY NEIGHBORHOOD
York is at the forefront of the “Smart Home” movement with their Hx™3 Touch-screen Thermostats and variable-capacity compressors. These systems don’t just blast cold or hot air; they modulate their output to match the precise needs of your home. This is especially beneficial in the Bay Area, where morning fog can quickly turn into afternoon sun. At Airstars, we focus on the “Total System Health.” By optimizing your unit’s airflow and refrigerant charge, we ensure you get the maximum SEER2 rating possible, keeping your home comfortable while minimizing your carbon footprint.
DECODING COMMON YORK ERROR CODES
York systems utilize a series of LED light patterns on the control board to communicate their status. These flashes act as a “check engine” light for your HVAC, and understanding them can help you identify a problem before it leads to a total system shutdown.
Code 2 Flashes: This indicates a system lockout due to a failed pressure switch, often caused by a blocked vent or a failing inducer motor that isn’t providing the correct draft.
Code 3 Flashes: This represents a pressure switch stuck open, which typically triggers when there is an obstruction in the flue or a problem with the intake air.
Code 4 Flashes: This is a high-limit switch fault, a safety measure that stops the system when it is overheating—usually due to restricted airflow from a dirty filter.
Code 5 Flashes: This signals a rollout switch trip, a serious safety warning that flames are being pushed out of the burner area, requiring an immediate professional inspection.
Code 7 Flashes: This represents an ignition lockout, occurring when the system has tried to light several times without success, often pointing to a faulty igniter or gas valve.
Code 11 Flashes: This is a communication fault, signaling that the indoor and outdoor units are no longer sharing data correctly across the control network.

YORK HVAC FAQS
Why is my York AC making a humming sound but not starting?
This is often a sign of a failing capacitor or a seized fan motor. In the Bay Area’s warmer months, capacitors can wear out due to high heat. It’s a simple repair that we can handle quickly to get your cooling back online.
What makes York’s "QuietDrive™" technology special?
York’s QuietDrive™ system uses a swept-wing fan and a sound-dampening compressor coat to reduce noise levels significantly. This makes York units some of the best options for homes with outdoor patios or neighbors close by.
How do I know if my York furnace is still under warranty?
York typically offers a 10-year limited parts warranty if the system is registered within 90 days of installation. If you aren’t sure, give us a call with your serial number, and we can look up your warranty status for you!
Do you install new York systems?
Yes. We install York air conditioners, heat pumps and furnaces and size the new equipment to the house and the existing ductwork.
Why is my York furnace short-cycling?
A dirty filter, a failing flame sensor, an overheating heat exchanger or a thermostat problem are the common causes. We test each one and fix the fault rather than resetting the furnace.
