What Are the Benefits of Mitsubishi Ductless Air Conditioning Systems?

July 18th, 2014

Many people rely on central air conditioning and heating systems to cool their homes. These two-unit systems blow cooled air through the ductwork of a building, but this may actually cost homeowners a lot of extra money every month.

Ducted air conditioning and heating systems often account for a lot of energy loss due to leaks in the ducts and poor insulation. Because of this, homeowners may end up spending money to cool unused spaces such as the attic or crawlspace. Another issue with ducted systems is that some homes do not already have ductwork installed, and installation may be difficult due to the layout of the home.

One solution is to install a Mitsubishi ductless air conditioning system. These systems are very energy efficient and can help you save money every month, and they also provide both cooling and heating so you won’t need to purchase a separate heating system.

Another benefit? No ducts! During installation, a technician will install a fairly compact condenser unit outside of your home, along with indoor air handlers in multiple locations throughout the home. Warm air enters the indoor air handler and is cooled by a coil, so that cool air can blow into the room. Refrigerant cycles through your entire AC system and releases the heat from your home outdoors.

Your home may require multiple indoor air handlers in different rooms or zones in order to cool the entire home, but a technician can mount these high on the wall so they won’t interfere too much with the interior design. Because there are multiple blowers, you can set the temperature to a different specification in each room via separate thermostats or with a master thermostat that controls each zone. This means your family members will be more comfortable in their own rooms, and it can also save you money. If only one family member is home, for example, only one air handler may need to operate, saving you money every month on your energy bill.

How Faulty Thermostats Affect Your Air Conditioning System

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.

Leading the Way with Independence Days!

July 3rd, 2014

The term “Fourth of July” is the popular name for the U.S. federal holiday officially known as Independence Day. It isn’t surprising that we would come up with a different name from the official one, since “Independence Day” is one of the most common holiday names across the globe. Most of the nations in existence today won their independence from another power, whether through wars, treaties, or long transitions.

What might surprise many people is how old U.S. Independence Day actually is compared to the similar holidays of other nations. Although the U.S. is still considered a young nation, it was one of the first to make a full break for its colonial master with a new constitution. Most countries that celebrate a national Independence Day are commemorating events that occurred in the second half of the 20th century, when many older empires at last relinquished control over their colonies.

How substantial is the difference in time for the U.S.A. and the rest of the world? U.S. Independence Day celebrates the signing of the Declaration of Independence from the Kingdom of Great Britain in 1776, making our country unusual in that almost no existing nations celebrate an independence event from the eighteenth century.

In terms of age, there is only a tiny handful current countries that celebrate an independence day that occurred earlier than the United States. Switzerland celebrates its independence from the Holy Roman Empire of the Germans in 1291 with “Swiss National Day,” held every August 1—although this only gained status as a national holiday in 1994. Sweden Celebrates “National Day of Sweden” to commemorate events in 1523 and the election of King Gustav I during the War of Liberation against Christian II of Denmark and Norway. Romania comes almost a hundred years after U.S. Independence, with its 1877 freedom from Turkish rule.

The most recent Independence Days to come into existence are for Montenegro, which gained independence from Serbia in 2006 and celebrates the day on May 21, and South Sudan, which gained independence from Sudan in 2011 and celebrates the day only a day after the U.S., on July 5.

Does anyone else celebrate a literal “Fourth of July,” an Independence Day that also falls on the fourth day of the seventh month? Yes: Abkhazia, a small Central Asian country that declared its independence from the Republic of Georgia in 1999 (although not all countries recognize it). Coming a day (like South Sudan) on July 5 is the independence of the small Atlantic island nation of Cape Verde, which became free from Portugal through signed agreement in 1975.

Everyone at Command A/C hopes you and your family enjoy a vibrant Independence Day/Fourth of July this year!

Causes of Reduced Cooling Power in Your AC

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

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?

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.

3 Benefits of Packaged Units in Orange County

June 9th, 2014

The most common type of air conditioning system found in homes is the “split” system, which has two cabinets: the outdoor condenser, which houses the condenser coil, fan, and compressor; and the indoor evaporator, which houses the evaporator coil and blower fan. The two units connect through power and refrigerant lines.

A split system isn’t your only option for air conditioning in Orange County, however. At Command A/C we offer installation of packaged AC units. What are “packaged air conditioning units”? They are similar to the rooftop units that businesses use for cooling and heating. All the important components are housed in a single cabinet: condenser, evaporator, compressor, fans.

Here are a few of the reasons that a packaged unit might be the right choice for your home:


Packaged units are much easier to service for HVAC professionals than split systems. It’s a quicker job to open the cabinet and diagnose problems when all the components are housed in one place, and there are far fewer refrigerant and power lines to worry about. The fast and efficient repair jobs will cost you less.

Save Space

A packaged unit takes up very little space inside your home, unlike the large cabinets needed for the evaporator. You’ll have valuable indoor real-estate freed up with a packaged air conditioner. Connected to the space-saving is the generally improved appearance of your home’s interior without the need for a piece of industrial machinery tucked away in a corner.

Quieter Operation

With all the fans, motors, and other moving parts placed outside your home, you will have reduced noise pollution indoors. Packaged units are among the least obtrusive systems you can install.

Heat Pump Options

Packaged units can also be installed as heat pumps, so not only will you have all the components gathered in one convenient place, but the single unit will take care of your cooling ­and heating needs.

This may sound like packaged units are the only choice for air conditioning an Orange County home. But there are some possible drawbacks, and the layout of your home may not make these systems practical for you. The best way to find out if you’re a fit for a package system is to call on expert installers today and arrange an appointment. If a packaged unit isn’t the ideal choice, the professionals will steer you toward other superb options.

The place to call is Command A/C: we have the years of experience and training, as well as the selection of top-brand models, to help you receive the best installation possible.

Causes of Puddles Under Your Air Conditioner

May 23rd, 2014

You probably do not think of water having much connection to the operation of your air conditioning. It’s not part of the plumbing, nor does it use the flow of water to provide comfortable temperatures the way a boiler does. Yet water is part of how an air conditioner carries out the job of heat exchange: as the indoor evaporator coil absorbs heat from your home, it also causes water vapor in the air to condense across the coil. The dripping sound you periodically hear from the AC is this water moisture dripping down into a pan, where a drain and pump safely remove it.

Under normal circumstances, you won’t need to give this water moisture much consideration. But there are occasions when you might notice water puddling around your AC: this indicates an issue that needs repairs before it can cause expensive damage and lower your comfort. Call for the skilled technicians at Command A/C for the necessary repair in Orange County, CA to stop the water leaking before it becomes worse.

Why are these puddles happening?

You can probably guess at why water leaking into your home is a problem: expensive water damage, pests and vermin, mold and mildew, and increased humidity in your home. The reasons for it to start are varied. Here are the three most common reasons:

  • Clogged drain or drain line: Like any drain, the one in the condensate pan can develop clogs that will slow or stop drainage of the water in the pan. Often algal growth is responsible. Because of how shallow the drip pan is, it will take no time at all for the condensation in it to overflow the pan and enter your home. Water overflow can often trigger a sensor switch that will shut off the air conditioning to prevent more overflow.
  • Detached pan/detached drain: If the pan and the drain become disconnected because the pan is dislodged (something that sometimes occurs because of amateur tampering in the cabinet) or the drain can break off because of corrosion. Water will start to spill out directly—and this is worrisome if you have furnace installed below!
  • Malfunctioning condensate pump: The electrically-powered pump sits further down the drain line, where it collects condensate until it reaches a certain level, and then the pump pushes the water out into the plumbing system. The pump could burn out and need replacement. Kinks in the line or bad connections could also cause it to stop pumping water from the condensate pan.

Since condensate problems can threaten to stop your air conditioning, lower your indoor air quality, and damage your home and furnace, don’t wait to call for help when you see water puddles around the AC.

Command A/C provides full service installation, maintenance, and AC repair in Orange County, CA. One call to us will take care of those leaks from your air conditioning.

Should You Consider a Heat Pump for Your Cooling This Summer?

May 23rd, 2014

Although the presence of the word “heat” would seem to indicate that a heat pump is anything but ideal to keep you cool during the summer, the truth is quite the opposite. When you are considering replacing your old air conditioning to ensure that you have a pleasant warm season with efficient cooling power, you should place a heat pump high on your list of possibilities.

Don’t make the decision regarding new air conditioning system installation without assistance from HVAC professionals. Despite the advantages, a heat pump isn’t the best choice for every home and budget. Call the expert installers at Command A/C today and talk to one of our AC specialists to get started with finding your ideal cooling solution.

Why Heat Pumps Are a Good Choice for Cooling?

  • Powerful Cooling: A heat pump is essentially an air conditioning system. It works in the same way: circulating refrigerant in order to move heat from one place to another. In cooling mode, a heat pump has the same level of cooling power as a standard air conditioner of comparable size. You won’t notice any difference—until it’s time to turn the heat on in the fall and winter…
  • Efficient Heating: …because heat pumps also functions as heating systems. The way they differ from air conditioners is that they can reverse the direction they move heat, and instead of absorbing heat from indoors and moving it outdoors, they absorb heat from outdoors and move it indoors. Heat pumps can sometimes struggle in climates that experience below-freezing temperatures; for Southern California winters, they are more than enough to keep a home warm.
  • Energy Savings: There’s another advantage to the heating function, which is that a heat pump does not use as much energy to provide heat than a furnace or a boiler. Heat pumps do not burn a fuel source to generate heat. Instead, they use electrical power to run components that move heat from one place to another. A 2011 government study found that a family of four can save 30% from their heating bills by switching from a furnace to a heat pump.

So should you make immediate plans to junk your old furnace as well as the old air conditioning and move in a heat pump? As tempting as a heat pump to replace an AC may sound, it isn’t necessarily the best system to have installed in your house. Some homeowners find that going with a standard air conditioner works better with their budget plans. Other houses with low levels of insulation may not benefit from the heating mode of a heat pump.

Call Command A/C today and we can assist you with professional air conditioning installation in Brea, CA that will deliver not only the best system for you, but also the necessary skill to install it so that it works for many years.

Schedule Air Conditioning Maintenance Before the Summer Hits

May 16th, 2014

Those spring temps are pretty fabulous, but after they are gone, we are in the heat of summer here in Orange County. Command A/C knows how uncomfortable it can get, and the last thing we want to see is our customers experiencing a mid-summer air conditioner breakdown. This is why air conditioning maintenance in Orange County is one of our specialties, and why we strongly recommend you do a spring tune-up every year.

Why Do Annual Spring Air Conditioning Maintenance?

Your air conditioner is a complex system of multiple parts and components that all work together to cool your property. If you haven’t used your system in a while, it is very likely that it has collected leaves, debris and dirt. In addition, if unknown problems began toward the end of last season, they most likely didn’t disappear. Wouldn’t you rather know about these problems on a nice, spring day rather than on a 90 degree day in July?

Here are some reasons why Command A/C recommends scheduling air conditioning maintenance for our Orange County customers:

Maintenance can preserve your A/C’s cooling capability – by testing your air conditioner in the spring via a regular maintenance visit, your air conditioning technician will be able to detect any existing problems that could deter or obstruct the cooling process.

Maintenance can potentially improve your air conditioner’s energy efficiency – lots of small items can interfere with your system’s ability to run efficiently. Typical problems are dirty air filters, refrigerant leaks and reduced air flow. By tackling these problems before summer, you are preparing your system to work optimally when it runs full-time.

Maintenance ensures your air conditioner gets cleaned – cleaning certain components of your air conditioning system is important. Areas that typically need cleaning are the fans, condenser coils, evaporator coils and the fins. Dirt and dust collection can create strain on an air conditioning system, so getting rid of the accumulated layer of dirt can make your system breathe easier.

Maintenance can prevent big repairs – by performing regular maintenance on your AC, your technician is more likely to catch potential problems before they become big problems.

Call Us to Schedule Spring Maintenance for Your Air Conditioner

Spring maintenance can help your system do what it should in the summer: keep you cool and comfortable when it’s hot outside. As we head into the summer, call Command A/C to schedule your spring air conditioning maintenance in Orange County.
