The Very First Labor Day Celebration

Friday, 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?

Friday, 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?

Friday, 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

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 Does a Mitsubishi Ductless AC Work?

Friday, 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!
