Frozen coil and AC noise repair in Monte Sereno: 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.

Monte Sereno 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.

James W., Monte Sereno

Replaced our 20-year-old furnace and AC with a heat pump. Clean install, explained everything, and our summer bill dropped noticeably. Great frozen coil and AC noise repair experience.

Anthony P., Monte Sereno

Our AC quit during the hottest week of the year and they had a technician at our Monte Sereno home the same afternoon. Fixed a capacitor, charged exactly what was quoted. Cold air within an hour.

AC Frozen Coil & Noisy AC Repair in Monte Sereno: 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 Monte Sereno is far cheaper than the motor or compressor it might save.
