Sub-Par Cooling Performance: Is Your AC Not Cooling as Expected?

Overview: The primary purpose of an air conditioning system is to cool your home efficiently. It can be frustrating if your newly installed AC isn’t meeting your expectations.

Cause: Insufficient cooling can be due to various reasons, such as improper sizing, air leaks in the ductwork, or a dirty air filter.


  • Verify if your AC is correctly sized for your home. If not, consult Precision Air Inc. to explore appropriate options.
  • Inspect the ductwork for any visible gaps or leaks and seal them with duct tape or mastic sealant.
  • Ensure your air filter is clean and replace it if necessary. Regularly changing the filter every 1-3 months can prevent this issue in the future.

Frequent AC Cycles: Why Is Your AC Turning On and Off Frequently?

Overview: Your new Vista, CA air conditioning system cycling too frequently can lead to higher energy bills and unnecessary wear on the system.

Cause: The most common cause of frequent AC cycles is a dirty or clogged condenser unit, obstructing proper airflow.


  • Turn off the AC and check the condenser unit. Remove any debris or vegetation surrounding it.
  • Clean the condenser coils using a soft brush or a specialized coil cleaner.
  • Schedule regular maintenance with Precision Air Inc. to keep your AC in optimal condition.

Uneven Cooling: Some Rooms Feel Colder Than Others

Overview: Uneven cooling can lead to discomfort, with some regions of your home feeling too warm while others remain chilly.

Cause: Inadequate insulation, improperly balanced ductwork, or a malfunctioning thermostat can cause uneven cooling.


  • Check your home’s insulation and add more as needed, paying close attention to attics and crawl spaces.
  • Have a professional technician from Precision Air Inc. inspect and balance your ductwork to ensure even airflow.
  • Verify if your thermostat is correctly calibrated, and consider upgrading to a programmable thermostat for better temperature control.

Strange Noises: Is Your AC Making Unusual Sounds?

Overview: Unusual noises from your AC can be alarming and indicate potential problems.

Cause: Rattling, grinding, or squealing noises could be due to loose components, faulty fans, or debris in the system.


  • Turn off the AC and inspect for any loose screws or components. Tighten them carefully if needed.
  • Check for debris inside the outdoor unit and remove it.
  • If the noises persist, contact Precision Air Inc. for a thorough inspection and repair.

Foul Odors: Why Is Your AC Emitting Unpleasant Smells?

Overview: If your air conditioner emits strange odors, it can significantly impact indoor air quality.

Cause: Mold or mildew growth inside the AC system or a dirty air filter can lead to foul smells.


  • Clean or replace the air filter to prevent odors caused by trapped particles.
  • If the smell persists, schedule a professional cleaning and maintenance service with Precision Air Inc. to eliminate any mold or mildew growth.

High Humidity Levels: Does Your Home Feel Too Humid?

Overview: Excessive humidity can make your home uncomfortable and promote mold growth.

Cause: Inadequate AC sizing, clogged condensate drain lines, or malfunctioning thermostats can cause high humidity levels.


  • Check if your AC is adequately sized for your home’s square footage. Contact Precision Air Inc. to confirm the appropriate sizing and ensure a seamless air conditioning installation in Vista, CA.
  • Clear the condensate drain lines from clogs or debris to ensure proper drainage.
  • Check the thermostat’s settings and calibration to ensure it is operating accurately. 

AC Not Turning On: Is Your AC Completely Unresponsive?

Overview: If your air conditioner fails to turn on, it could be due to electrical issues or a faulty thermostat.

Cause: Tripped circuit breakers, blown fuses, or a malfunctioning thermostat can prevent your AC from powering on.


  • Check the circuit breaker panel, reset any tripped breakers, or replace blown fuses.
  • Ensure your thermostat is set to “cool” mode and set at the desired temperature.
  • If the problem persists, contact Precision Air Inc. to inspect and diagnose the issue professionally.
