Common Heat Pump Repairs

Friday, August 8th, 2014

The heat pump is one of the most energy-efficient heating and cooling systems available for homeowners in Orange County. If your heat pump has kept you comfortable for multiple cooling and heating seasons, you may be surprised when your system runs into sudden problems. While heat pumps are generally quite effective, they are made up of many components, so they are likely to develop a few issues over time. The HVAC technicians at Command A/C have seen it all, so we’ve put together a list of some common AC repairs for heat pumps in Orange County.

Low Refrigerant

Your system is designed to hold a certain level of refrigerant at all times. Refrigerant cycles through your system, changing from a gas to a liquid to release heat and from a liquid to a gas to absorb heat from the air in your home. If refrigerant is low, your heat pump cannot transfer heat to the outdoors, which means you can’t receive any cool air inside.

Although refrigerant helps heat to release from your home, the refrigerant itself will never dissipate. Low levels indicate either an improper charge during installation or a leak. Leaks may lead to further problems with your heat pump, such as compressor damage, so you should call a professional at the first sign of low refrigerant, such as a hissing sound or limited cooling.

Faulty Reversing Valve

The reversing valve reverses the direction of refrigerant. So, in a heat pump, refrigerant can move heat from the indoors to the outdoors to cool your home, or it can move heat inside to provide heating in the winter. Like any mechanical part, the reversing valve may encounter problems over time and require repairs.

Thermostat Issues

If you notice that your heat pump is stuck in one mode, it may be a problem with the reversing valve. However, you may simply need a new thermostat. A new thermostat may be more accurate than an older model, allowing for more efficiency and better performance.

You should have a professional look at your heat pump at the first sign of a problem to prevent other damages. Call Command A/C for AC repair in Orange County today.

How Faulty Thermostats Affect Your Air Conditioning System

Tuesday, July 8th, 2014

Your air conditioning unit is an investment, and when you turn it on, you expect to forget it’s a hot day in Anaheim. So when your air conditioning won’t run properly, you may worry about costly repairs. While this is a definite possibility, one surprising reason you may need repairs is a faulty thermostat.

An air conditioning technician is the best person to determine what the source of the problem is. However, here are some of the ways a faulty thermostat could affect your air conditioning system.

System Won’t Start or Is Hard Starting

Of course, you know to call a technician when there is no cool air coming from your air conditioning, so that you won’t have to deal with the summer heat. But did you know that the thermostat may actually be at fault, even if it appears to be on? If your system won’t switch on at all, it is very likely that the thermostat cannot properly sense the temperature in your home. The thermostat tells your system when to turn on and off, so when a sensor inhibits this process, your AC will not know when to run. Similarly, a faulty sensor may cause the condenser unit to turn on and off repeatedly, also known as hard starting.

Inadequate Cooling

If you receive inadequate cooling from your AC system, but it is still blowing air, it could signify a variety of issues, including low refrigerant levels or blocked airflow. However, it may mean your system has trouble sensing the correct temperature or reading the desired setting on your thermostat. If you use a manual thermostat and your home always feels too hot or too cold, it may be because it is often difficult to set the temperature accurately with this kind of display. You may consider a new digital thermostat instead, which will also allow you the freedom to set the temperature to change automatically at certain times of the day.

At Command A/C, we can set you up with a new digital thermostat that won’t cause you as many problems as a manual thermostat might. Call us today for AC repair in Anaheim.

Causes of Reduced Cooling Power in Your AC

Friday, June 27th, 2014

People flock to Anaheim from all around the world for the summer season, where we enjoy warm weather that manages not to edge into the extremes of Los Vegas, Phoenix, or Santa Fe. However, it can still get hot, and if you have an air conditioner that begins to show signs of wavering in its steadfast task of keeping your home cool, you need to call for professional repairs immediately before you lose your valuable cool air.

There are a number of reasons that your air conditioner can start losing its cooling ability. Our staff at Command A/C is familiar with all these causes of reduced conditioning power and they know how to fix them. For all your needs for AC repair in Anaheim, CA, count on our outstanding service.

Here’s Why You Might Be Losing Cooling Power from Your Air Conditioning System

  • Clogged air filter: This is the #1 reason that ACs can start to struggle, and fortunately it is easily preventable. The air filter is designed to protect the interior of your air conditioner’s evaporator cabinet from contamination that enters through the return vents. The filter traps debris and allows the air to pass through. Over the span of a month, the debris trapped in the filter will build up to the point that it will choke off airflow. Reduced airflow means reduced cooling power. Change the air filter once a month during the summer and whenever else you use your air conditioner on a regular basis. If your cooling does not recover after changing the filter, call for repairs.
  • Loss of refrigerant charge: The refrigerant that cycles through an air conditioner remains at a set level known as its “charge.” Refrigerant does not dissipate or get used up during normal operation; however, leaks can cause the charge to drop, and when that happens the system will struggle to absorb the same level of heat that it once did. A decrease in refrigerant charge will also cause damage to the compressor, which can overheat, so call for repairs immediately that will seal the leaks and recharge the refrigerant to its proper level.
  • Impaired outdoor fan: The exterior fan plays an important part in the heat exchange cycle that cools down a home. It draws warm outdoor air across the hot refrigerant in the condenser coil, which allows the condenser to release heat to the outdoors, and then the fan vents away the heat. Should the fan malfunction (due to damage, broken motor, broken fan belt), the refrigerant will not release sufficient heat and then will be unable to absorb as much heat from the indoors. You should always leave the job of repairing the fan to professionals.

The best way to avoid AC repair in Anaheim, CA is with regular maintenance. Call Command A/C today and sign up for our Ultimate Service Agreement, which will deliver you two precision tune-ups a year (one for your AC, the other for your heater) as well as preferred service scheduling and a 15% discount on all service repairs.

Repairs That Will Make Your AC Run More Efficiently This Summer

Thursday, June 19th, 2014

Repairs obviously make your air conditioner run again, but they can also make your system run more efficiently, particularly if you can repair a problem in the early stages. Having your air conditioner run more efficiently, especially in summer, can make repairing your air conditioning system an important part of saving money.

Here are a few of the more common repairs our Command A/C professionals do that have helped our customers save money for the short- and long-term:

Refrigerant Leaks

Refrigerant leaks can be hard to detect; in fact, if they are small enough, they may not even be discernable to an untrained person. Not repairing a refrigerant leak means your system is operating with less refrigerant than it needs, which will put stress on it. Unfortunately, you can almost always count on refrigerant leaks to increase in size, so it’s best to have a technician find and repair them as soon as possible.

Fan Issues

There are two fans in your air conditioner. They are both responsible for air flow and helping with heat release and cooling, so if one starts to malfunction, these two processes get affected. Different problems can happen with your fans, ranging from motor issues to bent fan blades, but all fan problems should be addressed as soon as possible. Bent or loose fan blades tend to make a banging, clunking or bumping sound, and motor issues become evident with symptoms like a decrease in air flow or warm air blowing. Fans repairs are not DIY projects, as they involve a lot of small parts and electrical components, so it’s best to call a trained technician to repair them.

Repairs Can Mean Better Efficiency

Energy efficiency means less energy is being used, a savings you’ll see in your monthly utility bills. Getting repairs done before the problem/s can evolve into bigger issues will not only save you money and time, they will get your AC running more efficiently faster. Make your air conditioner work for you – call Command A/C and schedule air conditioning repair service in Long Beach, CA today.

Your AC Needs Repairs: Is It the Thermostat?

Monday, June 16th, 2014

One of the reasons you should always leave air conditioning repair jobs to licensed and trained professionals is that often it’s difficult to tell exactly what in an AC system has failed and requires fixing. Central air conditioners are complex devices that consist of multiple systems working together, and failure in one of them can affect the others. Your home’s air conditioner consists of the condenser, the evaporator and air handler, the ventilation, and the thermostat.

It’s the last of these that concerns us here. A malfunction in the thermostat can lead to problems elsewhere in the air conditioner that resemble major mechanical or electrical failures. When you call for air conditioning repair in Anaheim, CA because your AC either won’t turn on, won’t turn off, or cannot deliver the expected amount of cooling, one of the first things the technicians will check when they arrive at your house is the thermostat. Sometimes it will only take some rewiring and re-calibration to fix the trouble—although there are times when it’s advisable to replace an old thermostat with a new one.

At Command A/C, we are familiar with the ways that a malfunctioning thermostat can cause trouble. When you call us, we will quickly get to the bottom of the problem and restore your cooling.

Thermostat Issues That Will Affect the Entire AC

The most common trouble that afflicts thermostats is temperature reading miscalibrations. When the sensors in the thermostat start picking up readings either above or below the actual temperature, it will result in the air conditioner turning on and off at incorrect times. This will lead to energy waste and discomfort. Fortunately, this is a simple fix for AC technicians. If you have an older manual model thermostat, you may consider updating to a more precise digital model.

Wiring failures are another frequent issue with thermostats. Most thermostats use a set of five wires to communicate with the air conditioner, and each wire takes care of a single task. Losing a wire connection can result in AC fans and a compressor that won’t start or stop. These often resemble problems within the air conditioner, but will only require the technicians to fix the wiring problems in the thermostat.

Perhaps the biggest problem that a thermostat can have is poor placement within a house. If a thermostat is located in a spot where it encounters direct sunlight, exposure to drafts, or is placed too far from the center of the house, it will pick up “ghost readings,” false temperature recordings that will lead to erratic AC behavior and uneven temperatures. Usually, the thermostat will need to be moved to a better location to fix the problem.

Although thermostat repairs are frequently easier than other major issues with an AC, the malfunctions will cause larger problems to develop if left without attention. Whenever you sense that you need air conditioning repair service in Anaheim, CA, do not hesitate: call Command A/C right away.

Condenser Repair Issues with your Air Conditioning System

Wednesday, May 7th, 2014

Living in California means you really put your air conditioner to work, particularly during the summer months. When your unit works hard, it will start to see normal wear and tear. One of the components that can be affected by normal wear and tear is your condenser. If you have any concerns about the operation of your air conditioner, schedule professional air conditioning repair service in Anaheim with Command A/C.

The condenser is the part of the system that releases heat. The condenser consists of heat coils, fins and a fan, and if any one of these parts becomes damaged or broken, it can affect your whole air conditioning system. There are a number of things that can wrong with the condenser unit of your air conditioner:

  • Condenser fan won’t start
  • Condenser fan runs very slowly
  • Fan is making noises, such as ticking, clicking or buzzing
  • Fan blades get loose, start to wobble or become bent
  • Fan blades fully separate from fan motor
  • Fan won’t stop running
  • Coils are dirty
  • Coils have ice on them
  • Low refrigerant causes condenser to operate poorly
  • Bent fins

The first thing to know about any air conditioning repair is that it should be done by a trained professional. Why? Your air conditioner is a complex mechanical device; it runs on electricity and has refrigerant going through the entire system. This can create a wide margin for error and potential injury. Second, knowing what symptoms to look for can help your specialist pinpoint the problem faster. Here are a few symptoms that may indicate a poorly-running/broken condenser:

  • No air flow
  • Warm air flow
  • Significantly decreased air flow
  • Clanging or clunking noises (from fan)

How can your condenser contribute to or create these potential problems? Let’s start with the condenser fan.

The condenser fan blows the heat from the condenser coils into the air, helping the coils cool down. If the fan is malfunctioning, or not running at all, the heat transfer process can get interrupted, which can then affect the temperature of the air flow. Now let’s move on to the fins of your outside unit.

Outside air enters your AC system through the fins. Even though the fins are metal, they are easily bent. If they become bent, they can have a slowing-down effect on the airflow of your system because air is not getting through them. This can potentially slow down the airflow in your entire system.

Lastly, if you are hearing clanging or clunking noises coming from the area around the condenser fan, a blade may have become bent or loose. It is important to get this fixed as it has the potential to turn into a more serious problem.

How Do I Get My Air Conditioner Ready for the Summer?

Friday, April 4th, 2014

Long Beach enjoys less harsh summer seasons than some other Southern Californian cities because of our ocean breeze. But that doesn’t mean we’ll escape from needing air conditioners working in our homes: the sun beating down on a home turns into heat no matter the cool breeze outside. During the spring, when you can expect your air conditioner to have occasional, but not constant, work, you can take a few steps to prepare the system for its biggest job of the year: making summer pleasant.

To assist you with your AC preparations, call Command A/C and talk to our cooling specialists. We offer excellent air conditioning repair in Long Beach, CA from highly trained technicians.

How you can prep your AC for the summer heat

  • Schedule regular maintenance: You should have a maintenance visit from a skilled HVAC technician once a year to inspect your air conditioning system. Spring is the best time to have this done, since it takes advantage of a slower period for technicians and makes sure you have the time to see to any larger issues. Maintenance will not only catch repairs you’ll need done for the AC, it will also ensure that the system runs at its most energy-efficient so your summer will be less expensive while being more comfortable.
  • Take care of any repairs: You have probably already turned your air conditioning on at least once this year. Did you notice anything amiss? Examples: strange noises from the cabinet, odd smells from the vents, lukewarm air, low airflow, ice on the indoor coils. Anything of this sort means your AC requires professional repairs. Ignoring these issues now will mean headaches later, when you really need the system running to keep you cool. You also risk a complete breakdown on a hot day when HVAC technicians will be busy on other emergency calls.
  • Change the air filter: This is a part of maintenance you can take care of on your own, and it’s particularly important if you have a forced-air heater for the winter that uses the same ventilation system as the air conditioner. The filter catches particles that enter the return vents to stop them from contaminating the inside of the heater/AC cabinet. Congestion of the filter will cut off airflow and lead to debris getting through. The filter should be changed once a month during the height of heating or cooling season. To make sure your air conditioner starts summer with a clean set of “lungs,” put in a fresh filter.

The Trouble with Low Refrigerant

Wednesday, September 11th, 2013

Your air conditioning system uses a compressed refrigerant in order to remove heat from your home and exhaust it outside. This refrigerant is one of the key components of your AC and we here at Command A/C wanted to share some of the issues that can arise when your system has low refrigerant. Give us a call if you need any kind of Orange, CA air conditioning repair services.

Orange, CA Air Conditioning Repair: Low Refrigerant

Read on below for some of the common problems that can result from low refrigerant in your AC.

  • Not enough cooling – In order for your air conditioning system to effectively remove heat from your home, it needs to use a compressed refrigerant. This refrigerant is similar to Freon, but in newer models they use an environmentally friendly type. The refrigerant is actually the vehicle that carries the heat away from your home, so if there isn’t enough of it then you won’t get enough cooling in your home.
  • Noises – If there is low refrigerant in your air conditioning system, then you may start to notice a gurgling noise coming from it. This is the sound of air bubbles moving through the system.
  • Inefficiency – Without the proper level of refrigerant, your system will likely have to work harder to cool your home which will reduce its efficiency.
  • Ice on the coils – Your AC has a large fan that pulls in warm air from your home and passes it over a series of very cold coils (evaporator coils) which contain the refrigerant. Under normal operating conditions, condensation will form on the coils, similar to how condensation forms on a cold glass on a hot day, and drip into a drain. But with low refrigerant, this condensation will actually freeze and restrict the flow of air through the coils and, thus, into your home.

If you’re having any problems with your air conditioning system or if you suspect that you have low refrigerant, call the Orange, CA air conditioning repair professionals at Command A/C today.

How Low Refrigerant Leads to Air Conditioning Repair

Wednesday, August 28th, 2013

When you turn on your air conditioning system and it starts to cool your home one of the main reasons that it is able to accomplish that is because of the use of a refrigerant. We wanted to explain a little bit about how AC systems work and what can happen if your system has low refrigerant. Give us a call here at Command A/C if you need any kind of air conditioning repair services in Long Beach, CA.

How Air Conditioners Work

If you have a central air conditioning system then you likely have a “split” system which means that you have an indoor evaporator unit and a separate outdoor condensing unit. The evaporator is so-called because it contains the evaporator coils. Likewise, the condensing unit is called that because it contains the condensing coils.

These series of coils contain a compressed refrigerant. The evaporator coils get very cold and a fan in your home pulls in warm air from your home, passes it over the evaporator coils so that the refrigerant inside can absorb the heat from the air. The newly-cooled air is then pushed through your ductwork and into your home. The heated refrigerant is then circulated to the outdoor condensing coils where another fan blows outside air over the coils to exhaust the heat from the refrigerant.

You can see that if there isn’t enough refrigerant then your system could run into some serious problems. Here are a few of those problems:

  • Not enough cooling – If your AC system doesn’t have enough refrigerant then it won’t be able to absorb enough heat from your home. This will likely result in your home not getting cool enough.
  • Inefficiency – If there isn’t enough refrigerant in your home then your AC system will have to work harder to work with the amount that it has which will reduce its efficiency. If you notice that your energy bills are increasing even though you aren’t running your AC any more, it could be that you have low refrigerant.
  • Icing – Another common sign that you have low refrigerant is if your AC is icing up. You will likely notice it around the evaporator coils in the indoor unit.
  • Gurgling – If you hear your AC system producing a gurgling noise it could be that you have low refrigerant and the air bubbles in the lines are making that noise.

For any and all your air conditioning repair needs, contact the Long Beach, CA air conditioning professionals at Command A/C.

Common Air Conditioning Problems

Wednesday, July 10th, 2013

When you live in California it is important to have a high-quality air conditioning system that you can rely on to keep your home cool and comfortable on even the hottest days of the year. Of course, even top of the line products from the most established and respected manufacturers are still mechanical systems. This means that they are susceptible to operational problems. While most problems that you may encounter with your air conditioning system are not terribly serious it is still important to have them evaluated by a Cypress, CA air conditioning repair expert as soon as possible. Here are some of the most common air conditioning problems that we encounter at Command A/C, along with some possible causes.

If your air conditioning system simply will not turn on, do not automatically assume the worst. While it is possible that there is a very serious problem that has led to a complete breakdown, there are several other, far less serious possibilities. Check the power source of your air conditioning system. It is possible that the system has come unplugged or that the power line has frayed or been severed. Either way it can account for the complete lack of power. Never rule out user error, either. While it may sound obvious, check your thermostat. If it is set to heat instead of cool it will not activate. Double checking is never a bad idea.

Another common problem we see with air conditioning systems is freezing coils. The condenser coils on your outdoor AC unit are important to the operation of the system, and if they freeze up you system will fail to cool your home effectively. The most likely cause of this problem is a low refrigerant level. Your air conditioning system does not consume refrigerant, but rather recycles it over and over. This means that it is possible you have a refrigerant leak in your system. Contact a repair technician to find out for sure.

If you notice these or any other problems with the operation of your air conditioning system call Command A/C right away. We are the Cypress, CA air conditioning repair company to call for exceptional AC services. Let us help you cool your home consistently and reliably this summer.
