How Does Leaky Refrigerant Affect My AC?

Friday, October 31st, 2014

Leaky refrigerant is a common when it comes to air conditioning repairs. But just because it is common doesn’t mean it isn’t problematic. It is always important to repair refrigerant leaks as soon as possible as they become worse with time, and can cause further problems and possible damage to your system. Refrigerant must be handled by someone who is certified, so if you are experiencing a problem with your refrigerant, call AZ Air Conditioning and Heating today and schedule an appointment with one of our experts.

Problems from Leaky Refrigerant

Here are some of the problems that can develop from having a refrigerant leak in your system:


Your air conditioner was made to operate with an exact amount of refrigerant in the system. When a leak develops, the amount of refrigerant in your system drops, throwing the heat release/cooling process off balance. Icing occurs because the parts of your system that are warm stay too warm, and the parts that are cool stay too cold. Condensation develops between the two disparate temperatures, but then it quickly freezes, causing an ice build-up. Simply removing the ice from your system does not fix the problem; the leak needs to be repaired for your system to operate correctly.

Decreased Cooling

When your system can’t fully release the amount of heat it needs to due to a refrigerant leak, the entire heat release/cooling process is compromised, and can result in a loss of cool air. Finding a refrigerant leak can be challenging, so it’s best to schedule an appointment with a technician.

Compressor Issues

Your compressor pressurizes the refrigerant in your air conditioning system. The compressor is made to work with the specific amount of refrigerant your system needs; when that amount is altered due to a leak, the compressor can overheat and malfunction, causing system-wide problems.

Operating your air conditioner with leaky refrigerant can lead to further malfunction and breakdown. If you have a refrigerant leak, or suspect you have one, call AZ Air Conditioning and Heating today and schedule your air conditioning repair in Los Angeles.

Signs That It’s Time to Repair Your Air Conditioning

Friday, October 24th, 2014

Has it been a while since a technician has come to your home to look at your air conditioner? Do your utility bills seem to be much higher this month than in the past, even though the weather is beginning to cool down? Your air conditioning system uses up a large portion of your energy bills, as it must use a lot of power to be able to cool such a large space—your entire home. Unusually high bills may indicate that a worn down part is affecting the efficiency of your air conditioner and needs repair or replacement.

Scheduling prompt air conditioning repair service is vital if you want to make sure you keep your air conditioner for years to come. Keep an eye on your energy bills and look out for the following problems that may also indicate that your system is in jeopardy.

  • Reduced Cooling Capacity: Air conditioners wear down over the years, so it’s normal for some wear and tear to affect the performance of your AC. However, with regular maintenance, you should still have significant performance from your unit if it is not nearing the end of its life. Reduced cooling power may mean that a part may be failing, you could have low refrigerant, or you may only need a professional to clean the coils.
  • Strange Noises: Unusual noises can be anything from a low hissing sound to a loud banging or clanking from the outside unit. In any case, noises let you know that there is a major issue that must be addressed. No matter how seemingly insignificant the noise, it still requires immediate attention. A loud banging, for example, could indicate major compressor damage, or it could simply mean a fan needs a quick adjustment. A hissing sound could be even more problematic, as it likely indicates leaky refrigerant, which may cause your unit to break down.
  • Short Cycling: Short cycling, in which your system does not finish its cycle before it reaches the proper temperature, could indicate a problem with the thermostat. Unfortunately, it could also indicate major compressor damage.

Whatever the problem, contact AZ Air Conditioning and Heating right away for any type of air conditioning repair in Los Angeles. We have years of experience so that we can diagnose and repair your unit quickly and accurately. Call us today!

Air Conditioning Repair: Why Small Problems Matter

Friday, October 17th, 2014

Cooler weather is finally approaching, and here in Los Angeles we rely on our air conditioner less and less. This is good news for your energy bills and your comfort outdoors, but with such unpredictable weather lately, you may still need to use your air conditioner a few more times this year.

And when a minor repair need pops up, you may believe that you can wait to schedule service. After all, it won’t be long before you won’t need your AC at all, and you don’t want to pay now for a repair that can wait for the next cooling season. But this is risky thinking, as you may end up with a larger repair bill or other problems later on.

Small Problems Raise Your Energy Bills

One reason to schedule repairs as soon as possible is that you are spending a whole lot more to cool your home. Air conditioning is expensive as it is, but even a seemingly small matter can cause bills to spike. A loose fan blade, for example, cannot efficiently distribute the proper airflow over the evaporator coil. This means that your unit will have to run for longer periods of time to cool your home, consuming a lot of energy to do so.

Small Problems Worsen Over Time

Obviously, a small problem will not repair itself. And what’s worse is that it may actually become a much larger problem that can cost a lot more to repair. If you notice reduced cooling, for example, it could be a result of leaking refrigerant. And if you wait to call a technician, the refrigerant will only continue to leak from your system. Without enough of this chemical blend, the compressor cannot run as it should and may eventually fail.

You Need Your AC in Top Shape

The weather in Los Angeles has not exactly been stable recently. We simply don’t know what to expect from day to day. And since small problems may worsen, your system may break down during a sudden heat wave, right when you need it most. That’s why it’s important to get your system checked as soon as you notice any problem, from loud noises, to high bills, to reduced cooling power.

Air Conditioning Repair: Why Change the Air Filter?

Friday, October 10th, 2014

One of the best ways to help prevent repairs to your air conditioning system is to regularly change the air filter. A number of problems can develop from operating your system over a long period of time with a dirty or clogged filter, and they are problems that can be avoided simply by keeping a clean filter in your system. However, should you require any kind of air conditioning repair in Los Angeles, call the trained and certified experts who are available 24/7: AZ Air Conditioning and Heating.

Problems That Can Develop from a Dirty Air Filter

Here are some of the problems that can develop when you don’t change the air filter in your air conditioning system:

  • Decreased air flow – a dirty and/or clogged air filter can seriously restrict air flow in your system. As a result, the volume of air flowing through the system can noticeably decrease.
  • Icing on the evaporator coils – when the air flow is restricted in your system, one of the problems that can develop is ice build-up on the evaporator coils. This happens because the decrease in air flow causes an imbalance in the heat release/cooling process. As such, the parts that are warm stay too warm, and the parts that are cold stay too cold. This creates condensation, which quickly freezes on the colder parts.
  • Poor indoor air quality – when the air filter in your system becomes too clogged to trap dirt and dust particles, these particles will start to bypass the filter and enter directly into your system, where they can be blown into your living spaces.
  • Decreased energy efficiency – when your system has to work harder to achieve the temperature you want, it needs more energy to do so. With a clogged air filter, you run the risk of over-taxing your system, and as such, using more energy.

One of the best ways to manage any problems that can develop from a dirty air filter is to schedule bi-annual maintenance. During a maintenance appointment, your air filter is checked and replaced if needed. However, if you have developed problems from a clogged air filter, don’t wait to schedule air conditioning repair service in Los Angeles – call AZ Air Conditioning and Heating today!

To ensure that your repairs are taken care of properly and efficiently the first time around, hire the trained and certified professionals AZ Air Conditioning and Heating.

Common End-of-Summer Repairs

There are a number of things that can go wrong with your air conditioning system, but our technicians see certain repairs more often than others at this time of year:

Refrigerant Leaks

Refrigerant leaks can occur in a number of locations in your system. Low refrigerant levels can cause system-wide problems, including blowing warm air and icing on the evaporator coils. Refrigerant leaks can be difficult to find, and repairing them takes expert knowledge, as well as certification to handle refrigerant. If you suspect you may have a refrigerant leak, schedule an appointment with a trained technician.

Electrical Problems

Your air conditioning system has a number of electrical components in it. Examples of these types of components are wiring, capacitors and electrical terminals, just to name a few. During normal operation, it’s not unusual for these items to corrode and wear down, which can inhibit their proper operation. Unless you have expert knowledge of electricity and electrical systems, it’s strongly advised that you call a technician to handle any electrical repairs you may have.

Compressor Issues

The compressor in your system is a complex device that pressurizes the refrigerant in your system. When the compressor malfunctions, it can cause system-wide problems. Common problems with the compressor can involve the motor, the capacitors and faulty wiring. Compressor repairs require expert knowledge, so if you have an issue with your compressor, it’s best to call a trained technician for help.

As our temperatures cool, we have a great window of opportunity to schedule air conditioning repair service. Don’t let your repairs wait – call AZ Air Conditioning and Heating today and schedule an appointment with one of our specialists.
