Just give us a call at 310-933-3990, and our team will be there to help you promptly.

It is recommended to have your HVAC system checked at least twice a year for residential systems and four times for commercial.  Seasonal check-ups must include filter changes and our 17-point service to ensure optimal performance and energy efficiency. Regular maintenance helps prevent costly repairs and extends the lifespan of your equipment. Our maintenance services make it easy to keep your system in top operating condition.

At AC-Control, we prioritize customer satisfaction through our quality program.  All maintenance and installations are subject to our quality checklist.  Additionally, the A/C Control quality program is unique in the industry.  This quality program is backed by our weekly technical and performance training sessions to ensure the highest client satisfaction.

Yes, all of our A/C Control is licensed in California by the CSLB.  A/C Control is fully insured to protect our client’s best interests.  

Our highly qualified EPA 608 technicians are certified to perform HVAC services. They also regularly attend the most current training and certification education to ensure you can trust that your system is in capable hands with our experienced professionals.

Absolutely, improving indoor air quality is an essential aspect of maintaining a healthy and comfortable home or business environment. We offer solutions such as air purification systems, humidifiers, and ventilation services to enhance indoor air quality and reduce allergens and pollutants. Call 310-933-3990 for your air quality concerns.

If you notice any unusual noises or other signs of trouble with your HVAC system, it’s important to address them promptly to prevent further damage. Book an appointment or call 310-933-3990 and our qualified technicians will diagnose the issue and provide the necessary repairs or recommendations to restore your system’s performance.

Zoning an air conditioning or heating system is the addition of mechanical devices that separate your home or business in zones.  For example, you may wish to have the first floor as one zone and the second floor as another.  This allows for customized temperature control in different areas of the house or building. Our technicians can assess your property and recommend zoning solutions to enhance comfort and energy efficiency.

Easy, please call the office at 310-933-3990 to schedule an appointment.  You may also schedule an appointment online at ac-control.com and click book online.  One of our qualified technicians will arrive, troubleshoot your system and we will provide you a written invoice with the diagnostic, recommendations and a written quote.

There are several reasons why older systems need to be replaced.  Older systems, just like automobiles and other home appliances, are mechanical equipment that are prone to failure.  As systems age, the repair expenses just keep getting greater and greater.  Also, our older systems do not have the same technological capabilities for quiet operation and energy efficiency.  Save money on repairs, reduce the noise of your equipment and save money on electric bills.  Call A/C Control for a free and no-obligation in-home or at your business estimate.

A sudden spike in your cooling bill indicates your AC is running inefficiently due to mechanical failure. When components wear down or airflow is restricted, the system must run longer to satisfy your thermostat. This prolonged runtime directly translates to increased electricity ($$) consumption.

• Clogged Air Filters: The blower motor must work harder.
• Dirty Condenser Coils: The compressor must work harder.
• Low on Freon: Leaks in freon does not allow the system to cool – tip: do not just top off, fix that leak.

* Failing Capacitors: The compressor must work harder with weak electric parts.

The AC evaporator coil freezes when the temperature below 32°F. This is typically caused by a dirty filter or a freon leak.

1. Thaw the System: Set your thermostat from “Cool” to “System Off.”
2. Run the Fan: Set the fan to “On” to blow warm air over the ice.
3. Replace the Filter: Put in a clean air filter.
4. Call A/C Control: Schedule an inspection to check for low refrigerant or duct leaks.

An indoor AC water leak can be caused by a blocked condensate drain line. Water condenses is a natural reaction to cooling the air. If the drain line gets clogged, that water backs up and overflows the internal drain pan into your ceilings or floors.

Yes, a leaking air conditioner is a home improvement emergency. Beyond causing immediate water damage to drywall and flooring, stagnant water creates a breeding ground for biological growth. Shut off your thermostat immediately.

Unusual air conditioning noises means loose or damaged parts. Modern A/Cs should operate with a steady, predictable hum. Any sharp, metallic, or rhythmic disruptive sounds require A/C Control’s technician to diagnose and repair the equipment.

• Squealing or Screeching: Indicates a failing blower motor belt or bad bearings.
• Banging or Clanking: Indicates a loose compressor internal.
• Hissing or Bubbling: Indicates a freon leak.
• Clicking Repeatedly: Indicates an electrical issue with a relay, contactor, or thermostat connection.

As of January 1, 2020, R-22 refrigerant is illegal to produce or import in the United States. While technicians can legally use recycled R-22 to service older systems, the available supply is scarce and costly. Most R-22 systems must be completely replaced when a major leak occurs.

The primary risk is exorbitant repair costs. A simple freon recharge can cost thousands of dollars due to scarcity. Additionally, these systems are well past their engineered lifespan (they were all manufactured before 2008), making them prone to sudden mechanical failures during peak summer heat waves.

This is a common mistake. Is freon R-22? Is it for all refrigerants and air conditioners? Freon™ is a brand name for the company that manufactures refrigerants. Freon is a common use referring to all types of refrigerant.
