My sister and I have both used this company and have both had excellent support. Seth was my electrician and as someone who is not technically minded it was a relief how well he met me on my level to explain things. The work was timely and tidy. It was a great experience. All the things I needed done were done well.

AC Repair FAQ’s

This is one of the most common calls we get in Southern California. If your system is blowing room-temperature or warm air, the most likely culprits are:

Clogged Air Filter: A severely dirty filter chokes off airflow, making it impossible for the chilled air to circulate through your ductwork.

Low Refrigerant: Often caused by micro-leaks. If you live in coastal areas like Pacific Beach or La Jolla, the salty marine air can accelerate corrosion on your condenser coils, leading to these leaks.

Dirty Condenser Coils: If you live inland where it gets dusty and dry, a layer of dirt on your outdoor unit can trap heat, preventing the system from cooling the air.

Air conditioners should operate with a steady, quiet hum. If yours is being highly vocal, turn it off immediately at the thermostat to prevent further mechanical damage, and call a professional.

Rattling or Banging: Typically means a component has come loose, such as a fan blade, motor mount, or debris trapped inside the outdoor unit.

Buzzing or Clicking: Usually indicates an electrical issue, such as a failing capacitor or a faulty contactor relay.

Squealing or Screeching: Often points to a worn-out blower motor belt or bearings that need lubrication.

This rapid on-and-off cycle is called short cycling, and it puts immense wear and tear on your system while spiking your SDG&E utility bill. Short cycling is often caused by restricted airflow (like a heavily clogged air filter) or an improperly calibrated thermostat. However, it can also happen if your system is low on refrigerant, which causes the evaporator coil to literally freeze solid, forcing the system to shut down protectively until it thaws. In some cases, it means the AC unit originally installed in your home is oversized for your square footage, causing it to cool the space too rapidly and shut down before completing a full cycle.

Yes, but you have to treat the root cause, not just the ice. If you check your indoor unit and see ice buildup, immediately turn your thermostat from “Cool” to “Off,” and turn the fan setting to “On” to help it thaw. A frozen coil is almost always a symptom of severely restricted airflow (check your filter!) or a refrigerant leak. Once the ice melts, our technicians can inspect the coil. If a refrigerant leak is present—a frequent issue for older San Diego units exposed to coastal moisture—we can locate the leak, patch it, and recharge the system. If the coil is heavily corroded beyond repair, we will discuss cost-effective replacement options.

Seeing water pooling around your indoor unit or noticing water stains on your ceiling or walls is a clear sign you need an urgent AC repair. During San Diego’s muggy late-summer months or the humid mornings of “May Gray” and “June Gloom,” your air conditioner works overtime extracting moisture from your home’s air. This condensation is supposed to flow safely outdoors through a condensate drain line. If water is backing up into your house, the most common culprit is a clogged drain line—usually blocked by a buildup of algae, dust, or mold—or a rusted, cracked drain pan. Ignoring this kind of leak can quickly lead to expensive water damage and mold growth in your drywall, attic, or flooring. Our technicians can swiftly flush and clear the blockage, repair damaged components, and ensure your system drains properly without putting your home at risk.
