Fresno CA Air Conditioning Repair Tip: Common AC Problems

Tuesday, April 30th, 2013

We’ve only just begun the cooling season here in Fresno, CA, but it’s never too late to ensure that your AC is running smoothly. With professional routine maintenance, you can greatly reduce the risk of even some of the most common minor air conditioning repairs. But, like with any mechanical system, some problems are inevitable. If your AC isn’t turning on, or won’t operate properly, then make sure you hire a certified technician to fix the problem. In this post, we’d like to review some of the most common AC problems. For comprehensive Fresno CA air conditioning repair, call the experts at Shaw’s Air Conditioning and Heating today!

  • AC won’t turn on. If it’s hot and humid outside, you need your AC to work properly. If your AC wont’ turn on, then there can be numerous things wrong with its operation. First, check to make sure that it hasn’t blown a fuse or tripped the circuit breaker. You should also ensure that the thermostat is set for cooling and its setpoint is lower than the current indoor air temperature. If neither of those quick fixes works, then you may have an electrical problem in the supply line, or a bad capacitor.
  • Hissing sound. If you hear a hissing sound in or around the coils or refrigerant piping, then you may have a refrigerant leak. Even the smallest puncture can allow gaseous refrigerant to leak into the outdoor air. This can dramatically reduce your cooling performance and efficiency over time.
  • Frozen evaporator coil. While the sight of frost may be a welcome sight for Fresno residents on a summer afternoon, a frozen evaporator coil is typically related to an airflow problem. Check your air filter to make sure it’s not dirty or clogged with dust and debris. When your coil freezes, it will not be able to cool the air brought into the air handler by the blower, and this can result in various problems, such as inadequate cooling in your home and an overheated compressor.

Fresno CA Air Conditioning Tip: How to get your AC ready for Spring and Summer

Tuesday, April 23rd, 2013

As the temperature begins to rise in Fresno, CA, homeowners throughout the area are looking for ways to get more from their air conditioning systems this spring and summer. Considering the duration of the cooling season, it’s no wonder that it’s on our minds. In this post, we’d like to review some ways you can get your AC ready. While professional installation and routine maintenance are critical to the efficiency and effectiveness of your system, there are still other things to be done. When you need excellent Fresno CA air conditioning, contact the pros at Shaw’s Air Conditioning & Heating, Inc.!

  • Regularly change your air filter. All air conditioning systems contain an air filter that’s designed to filter out particles that could potentially damage or otherwise impact the operation of the cooling system. During the spring and summer, it’s important to change your air filter on a regular basis, so that it doesn’t begin to impede airflow, causing wasted energy as well as potential system damage.
  • Install a programmable thermostat. If you have a conventional manual thermostat, consider upgrading to a programmable model. Not only will it enable you to create a schedule of cooling based on your needs, but it will also reduce your energy bill by eliminating cooling during times when your home is unoccupied.
  • Clean and clear. Make sure that you don’t have any vegetation looming on the exterior of your outdoor unit. When high grasses or loose branches begin to invade the area on which your AC sits, it can create airflow issues, as well as potential mechanical damage. By keeping all aspects of your AC clean and clear, you can ensure that it operates well for the years to come.

We hope you found this list helpful. If you would like more information about how we can improve your air conditioning system, contact Shaw’s Air Conditioning & Heating, Inc. to speak to one of our Fresno, CA air conditioning technicians.
