3 Problems That Can Affect Energy Efficiency

September 9th, 2014

Even though summer is coming to a close, you can still maintain and improve energy efficiency. One of the best ways to do this is to make repairs as quickly as possible. There are a number of problems that can affect the energy efficiency of your air conditioning, and we’ll outline three of them here today. But whatever your repair needs, always call the people you can trust: Command A/C.

3 Common Problems That Can Affect Energy Efficiency

Refrigerant Leaks

Refrigerant leaks can occur in multiple places in your air conditioning system. The refrigerant in your system has to be at an exact amount for your AC to work properly; leaks lower the amount of the refrigerant, putting stress on the system. Anytime your AC has to work harder to achieve your set temperature, it uses more power to do so, increasing its energy usage.

Clogged Air Filters

The air filter in your air conditioning system should be changed every 3 months as it can become clogged. Clogged air filters restrict air flow in your system, which can cause a decrease in cooling. Restricted air flow also forces your system to work harder to cool your home, which can increase its energy usage.

Dirty Coils

Your air conditioner has two sets of coils: the evaporator coils and the condenser coils. During normal usage, dirt and dust can build up on the coils. If they are not cleaned annually, this buildup can become a layer that acts as insulation on the coils. This layer can interfere with the heat release/cooling process of the refrigerant cycle, which stresses your AC.

Even though the end of the cooling season is near, it’s still important to maintain your energy efficiency. Making repairs as soon as possible helps you maintain your energy efficiency and keep your air conditioning running optimally. Also, scheduling bi-annual maintenance in fall and spring can help with all of these problems. If you are experiencing issues with your air conditioner, call Command A/C and schedule AC service in Cypress, CA with one of our experts today.

The Very First Labor Day Celebration

August 29th, 2014

Labor Day as a federal holiday, held on the first Monday of September, has been with us now for 120 years. President Grover Cleveland signed the law that made Labor Day a national holiday in 1894. Ever since then, the three-day weekend has provided people in the U.S. with the opportunity for vacations, time with their families, shopping trips, and a general celebration of the conclusion of summer and the beginning of fall.

However, there were twelve years of Labor Day observations in the U.S. before it became an official holiday. The first Labor Day celebration took place in 1882 in New York City on September 5. According to the accounts from the time, it had a rough start and almost didn’t happen.

The main event planned for that first Labor Day was a parade along Broadway that was to start at City Hall. However, the parade ran into a bit of a snag early on. The marchers started to line up for the procession around 9 a.m., with a police escort to make sure the event went peacefully. However, the problem of the day wasn’t rowdy members of the parade—it was that nobody had remembered to bring a band!

With people ready to march, but no music to march to, it started to look like no parade would happen at all, and the first Labor Day would have ended up a failure. But just in time, Matthew Maguire of the Central Labor Union—one of the two men who first proposed the celebration—ran across the City Hall lawn to the Grand Marshal of the parade, William McCabe, to inform him that 200 men from the Jeweler’s Union of Newark were crossing the ferry to Manhattan… and they had a band!

At 10 a.m., only an hour late, the band from Newark walked down Broadway playing a number from a popular Gilbert and Sullivan opera. They passed McCabe and the other 700 marchers, who then fell in line behind them. Soon, the spectators joined in, and an estimated 10,000 to 20,000 people marched through Lower Manhattan.

According to the New York Times, “The windows and roofs and even the lamp posts and awning frames were occupied by persons anxious to get a good view of the first parade in New York of workingmen of all trades united in one organization.”

The parade concluded two hours later when the marchers reached Reservoir Park. But the party was only getting started. Until 9 p.m., some 25,000 people celebrated with picnics and speeches and beer kegs. It was an enormous success, and all thanks to the speedy arrival of jewelers carrying band instruments.

If those musicians from Newark hadn’t shown up, perhaps we wouldn’t have the holiday opportunity that we now have every year. However you celebrate your Labor Day, our family at Command A/C wishes your family a happy end of summer.

What Is a Packaged Unit?

August 22nd, 2014

Many homeowners are familiar with split-system air conditioners, systems in which both an indoor and an outdoor unit are needed to cool the air. The indoor air handler contains the components which remove heat from the air. The outside components help heat to release into the air. A different kind of system is the packaged unit, a type of air conditioner used in both residential applications and on many larger commercial properties. A packaged unit contains all of the same components of a standard system. In fact, the only difference between a packaged unit and a standard AC system is that a packaged unit combines all of the parts into one cabinet so that an indoor unit is not necessary.

In traditional air conditioning systems, refrigerant cycles through the indoor and outdoor portions, undergoing several phase changes which allow for the heat exchange process to occur. First, refrigerant enters the outdoor compressor unit, compressing into a high-pressure gas. This allows it to move to the condenser coil, where it changes into a liquid, giving off heat in the process. Indoors, the expansion valve helps to lower the pressure of the liquid before it moves into the evaporator coil. This coil allows refrigerant to evaporate into a gas, absorbing heat from the home. An indoor blower fan helps with the evaporation process and sends cool air through the ducts before the process begins again.

In a packaged unit, all of these parts are in one large cabinet. This cabinet is usually installed outside of the building or on the roof and connects directly to the ducts. This is useful for many reasons. When you need repairs or maintenance, the job may be completed more quickly as a technician can find all of the parts in one area. Additionally, this type of system is beneficial for homes and buildings in which indoor installation is not a possibility, and many homeowners appreciate the aesthetic value of an out-of-the-way rooftop cabinet.

While packaged units may have many advantages, they may not be right for every home. To speak to an expert about air conditioning installation in Orange County, call Command A/C today!

What Is a Packaged AC?

August 15th, 2014

There may be more options for your new air conditioning system than you realize. Many people are familiar with conventional central air conditioning units. These are split-system units in which one portion of the air conditioner is installed outside while an indoor unit, such as a furnace or air handler, is installed inside. The indoor portion usually connects to the ducts which supply cool air to the home. In this short guide, we focus on a different type of air conditioner, the packaged AC unit, in which all of the parts of a standard air conditioner are combined into one cabinet.

In a conventional central air conditioning system, the indoor unit absorbs heat from the home while the outdoor unit releases it outside. The outdoor unit contains several parts including the compressor and condenser. The compressor adds pressure to the refrigerant so it can make its way to the condenser, where it turns into a liquid and gives off heat. Inside, the expansion valve lowers the pressure, and then the condenser turns it back into a gas as it absorbs heat.

Packaged systems combine all of these parts into one unit. A large cabinet holds the fans, compressor, condenser, expansion valve, and evaporator, and connects directly to the ductwork. This unit may be positioned right outside the home, but it is often placed on the roof. This is ideal for many homes in which installing an indoor unit would be inconvenient. A packaged unit may be an efficient, space-saving system for many people.

While many homeowners use packaged AC units, these systems are ideal for businesses as well. Because the cabinet is located on the roof, technicians can repair or maintain a system and keep out of the way of customers and clients. Large packaged systems are also available for commercial installation. Also, many of these units are modular, meaning a technician can adjust the cooling capacity should the needs of the business change.

Common Heat Pump Repairs

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 Does a Mitsubishi Ductless AC Work?

August 1st, 2014

Ductless air conditioners are a great solution for many homes or rooms in which installing central air conditioning is not a possibility. While many homeowners without ductwork choose to install window or small room air conditioning units, these may be noisy, inefficient, and unable to cool large areas. Mitsubishi ductless AC systems are the best choice for many homeowners due to their high performance and efficiency and their ability to cool multiple rooms with separate thermostats.

How Does Ductless Air Conditioning Work?

With a traditional split-system air conditioner, the outdoor condenser unit connects to a single indoor air handler. The air handler or furnace connects to the return and supply ducts in the home. The return ducts suck in the air from the home while the supply ducts distribute the now-cooled air to the home. With a ductless system, the air handler is mounted directly onto the wall, eliminating the need for ductwork. The air handler both pulls in air from the living space and pushes the air back out after it is cooled. The installation requires only a tiny hole drilled into the wall so that the refrigerant line can run between both units.

Each outdoor unit can usually accommodate up to four indoor air handlers for even cooling throughout the home. Each air handler is also controlled by its own thermostat, or you can control every unit with a master thermostat. This means you can keep the air running in certain areas of the home and save money by shutting it off in other areas.

Is a Mitsubishi Ductless AC Right for Me?

There are many benefits of Mitsubishi ductless AC systems. Ductless air conditioners tend to have a higher SEER (Seasonal Energy Efficiency Ratio) than central air conditioners, which means you may see significant savings every month. Zone control is another appealing feature since your family members can set the temperature in different areas of the home to their own preferences.

However, ductless air conditioning may not be right for every home. The best person to speak with about ductless installation is an air conditioning professional. For Mitsubishi ductless AC installations in Orange County, CA, call Command A/C today!

Is a Mitsubishi Ductless AC System Right for My Home?

July 25th, 2014

If you need a new air conditioning system in Cypress, you may want the system that will give you the best possible performance and efficiency. Purchasing a Mitsubishi ductless AC system is a great way to cool your home and use less energy than with many central AC systems, but ductless air conditioning may not be right for every home. So when is a Mitsubishi ductless AC the right choice?

There Are No Ducts Currently Installed in Your Home

If your home does not currently use a ducted system, a Mitsubishi ductless AC may be the perfect choice for you. Ductless systems have both an indoor and outdoor unit, much like central air conditioners. However, the indoor unit of a ductless system is mounted directly onto your wall, with up to four indoor blowers per outdoor unit. This means you can get cool air supplied throughout your home without installing any bulky ductwork.

You Want Increased Efficiency

Ductless air conditioners are very efficient systems, as they often have high SEER (Seasonal Energy Efficiency Ratio) ratings. The SEER, printed on the EnergyGuide label of any AC, rates the efficiency of a unit, so a higher SEER may help you save a lot of money on your energy bills every month. Mitsubishi ductless systems often have higher SEERs than many ducted systems.

Zone Control Could Benefit Your Household

Another way you can save money is with zone control. Each air handler usually has its own thermostat, or you can control the temperature with a master thermostat that controls them all. If two rooms tend to be unoccupied throughout the day, you can save money by turning off the AC or raising the temperature for those rooms only. Zone control can benefit your family in many ways. Often, different members of your family have different temperature needs. With a ductless system, the temperature can be adjusted in each room to meet the needs of each family member.

While many homeowners can benefit from ductless systems, talk to the people at Command A/C to make sure they are an option for your home. To install your Mitsubishi Ductless AC in Cypress, call us today!

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!
