Frozen coil and AC noise repair in Union City: what we fix

A frozen evaporator coil is almost always caused by low refrigerant, a dirty filter or coil, a failed blower motor or closed vents restricting airflow. We thaw the coil, correct the cause and verify the refrigerant charge. For noisy units we inspect motors, bearings, fan blades, contactors, capacitors and panels, tightening or replacing whatever is worn so the system runs quietly again.

Union City customers on our frozen coil and AC noise repair

Had them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.

AC Frozen Coil & Noisy AC Repair in Union City: frequently asked questions

Why is my AC freezing up?

Restricted airflow (dirty filter, dirty coil, weak blower) or low refrigerant. Turn the AC off, set the fan to on to thaw the coil, and call us to fix the cause.

Is a buzzing AC dangerous?

A loud buzz that does not start the unit often means a failed capacitor or contactor. Continuing to try to run it can burn out the compressor, so it is worth a quick service call.

Can I keep using the AC if it is noisy but still cooling?

Some noises are harmless, but grinding and banging usually get worse fast. A quick inspection in Union City is far cheaper than the motor or compressor it might save.
