Air Conditioning Repair: Is It an Electrical Problem?

Monday, September 29th, 2014

As an electro-mechanical device, your air conditioner will most likely experience electrical problems at some point. Electrical problems can be complex, and electrical repair for your air conditioning system should only be handled by a trained professional. There are a number of ways your system can indicate there is an existing electrical problem, and some electrical problems are more common than others. The technicians at AZ Air Conditioning and Heating have experience with every kind of air conditioning repair, so if you are experiencing problems with your AC, call us today!

Signs of Possible Electrical Problems

Here are some common signs that can indicate the need for electrical repair:

Sounds

Buzzing, popping and cracking are all sounds that can be indicative of an electrical problem. While it may be tempting to see for yourself what the problem is, it is best to leave that to your technician. If you hear these sounds, turn off your system and make an appointment for repair.

Burning Smell

Some electrical problems can cause overheating, which can melt the plastic surrounding the wires. If you smell burning, turn your system off immediately and call for assistance.

Intermittent Performance

When wiring frays or corrodes, it can cause surges in the electrical flow, which can cause a component to run erratically. The wiring in your system is complex, so it’s important to allow a trained technician to determine exactly where the problem is.

Common Electrical Problems

  • Wiring issues – as mentioned above, wires can fray, corrode or disconnect, which can slow or completely stop the electricity in a certain part of your system.
  • Capacitor issues – there are two commonly-used capacitors in your AC system: a start capacitor, which supplies the boost to the motors in your system at the start of a cycle, and a run capacitor, which are needed to keep the electricity in the motors flowing evenly. When either of these capacitors has a problem, it can affect the operation of the motor and your system.
  • Tripping circuit breaker – your air conditioner likely has its own circuit breaker in your electrical box. Sometimes this breaker can trip, causing the system to shut down. Breakers trip as a safety precaution, so you should never force a breaker back on. Instead, call for your technician, who can determine the cause.

Electrical problems can be complicated, and attempting to repair them yourself can be dangerous. If you are experiencing electrical problems, call AZ Air Conditioning today and schedule air conditioning repair service in Los Angeles.

How a Faulty Thermostat Affects Your Air Conditioning

Friday, September 19th, 2014

Thermostats can malfunction just as easily as any other component in your HVAC system. A thermostat can malfunction for a number of reasons, but no matter the cause, the result can be problems for you and your air conditioning system. While thermostat repair is not as intricate as finding a refrigerant leak, it’s still important to call for a professional. With AZ Air Conditioning and Heating, you can rely on our trained technicians to repair any malfunctioning thermostat in your home.

What Happens When a Thermostat Malfunctions?

There are a few ways a malfunctioning thermostat can adversely affect your air conditioning system:

  • Short-cycling – a thermostat “short-cycles” when it turns off and on too frequently. Short-cycling can cause damage to your system and increase the level of wear and tear.
  • Problems with energy efficiency – if your thermostat is reading the temperature incorrectly, this can lead to an increase in energy usage.
  • Lack of comfort – a malfunctioning thermostat can make your indoors feel uncomfortable by providing too much or too little cooling; humidity levels may also be affected.

Most Common Problems with Thermostats

Here are some of the most common problems our technicians see when it comes to thermostat repairs:

  • Dirt and dust in thermostat – dirt and dust can get into the instrumentation of your thermostat and hamper its operation. Having the thermostat cleaned by your technician should resolve these problems.
  • Thermostat isn’t level – your thermostat needs to be level in order to work properly. If it is tilting to one side or another, the technician will make it level.
  • Drafts surround the thermostat – if your thermostat is in a drafty area, the drafty air can affect the how the thermostat reads the air temperature; this can result in faulty readings. Placing the thermostat in a better location can alleviate this problem.

Thermostats aren’t the most complicated component of your air conditioning system, but that doesn’t mean that can’t cause serious problems. If you are seeing the signs of a potentially faulty thermostat, call AZ Air Conditioning and Heating today and schedule AC service in Los Angeles with one of our experts.

Air Conditioning Guide: The Condenser Unit

Friday, September 12th, 2014

During a Los Angeles heat wave, you can count on getting a lot of use out of your air conditioning system. So when you walk outdoors this month, you may often be greeted by the hum of the large condenser unit. But if you don’t know much about air conditioning systems, you may not know about the components nestled inside, how they work, and, most importantly, how to keep them maintained. To give you a better understanding of the importance of this unit, we’ve put together a guide to some of the key components.

Compressor

The compressor is one of the most important parts of your air conditioner, adding pressure to refrigerant so that it can pump through the indoor and outdoor units. The compressor needs certain environmental conditions in order to work properly, including the proper amount of refrigerant. When refrigerant is too low, the compressor may struggle to run, and it might overheat. Be sure to call for repairs if you hear any strange noises or notice reduced cooling, as it may indicate a problem with this costly part.

Condenser Coil

Another important component in the condenser unit is the outside coil. This allows refrigerant to give off heat as it condenses from a gas to a liquid. If this phase conversion cannot take place because the condenser coil is dirty or blocked, you may feel warm air from the vents in your home. That’s why it’s important to schedule regular maintenance to get this coil cleaned and inspected once or twice a year.

Fan

The fan is responsible for assisting in the condensation process. Condensation occurs when warm outdoor air blows over the coil, and the fan then helps heat from the refrigerant to dissipate in the air. This process may be in trouble if a fan blade is damaged or if the fan motor is faulty.

Be sure to talk to an air conditioning expert at the first sign of problems, and schedule maintenance regularly to discover repair needs before they become a major problem. To learn more about air conditioning services in Los Angeles, call AZ Air Conditioning and Heating today!

How Does Solar Air Conditioning Work?

Friday, September 5th, 2014

We have a lot of sunny days here in Los Angeles, so it’s no surprise that solar air conditioning is becoming a popular choice among homeowners. There are a lot of questions when it comes to installing a solar air conditioning system in Los Angeles, the most common concerning how a solar AC works. The answer is that it’s pretty simple – and as long as you’ve hired professionals for the installation, like the trained experts at AZ Air Conditioning and Heating, you can enjoy the benefits a solar AC offers.

How Does Solar AC Work?

There are a few ways solar air conditioning can be installed, but the most effective way is by powering your air conditioning system via photovoltaic (PV) panels. PV panels use the energy from the sun to generate an electrical current. This electrical current is then used to power whatever you want, including your air conditioning system. Electrical energy is stored in batteries, and the system uses the solar power as long as possible. If another power source is needed, your AC will automatically switch to your back-up power source.

Benefits of Solar-Powered Air Conditioning

There are several benefits to solar-powered air conditioning worth considering:

  • Reduced energy costs – solar power can reduce your monthly electric costs up to $50 per month.
  • Long lifespan – solar panels have a lifespan of 25-30 years.
  • Reduced carbon footprint – by utilizing solar energy, you reduce your home’s carbon footprint as well as that of your power plant.

Always Hire Professionals

Proper installation is key for any air conditioning system, particularly for a system like a solar AC. It is also important to work with a company that can provide the repair work you may need in the future. This is why it’s essential to hire trained professionals who have the experience and knowledge to keep your solar air conditioner operating as necessary.

If you think solar air conditioning in Los Angeles may be an option for you, call the experts who have helped LA customers since 1984: AZ Air Conditioning and Heating.
