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 Shaw’s Air Conditioning wishes your family a happy end of summer.

3 Common Compressor Problems

Friday, August 22nd, 2014

There are three key parts to your air conditioning system: the compressor, the condenser and the evaporator. All three work together in the refrigeration process to release heat and condition your air. The compressor and condenser reside in the outdoor unit while the evaporator resides indoors, typically in your basement or attic. The compressor’s role in the refrigerant cycle is to pressurize the cool, low-pressure, gaseous refrigerant that enters it from the evaporator. Should problems ensue with the compressor, this process won’t unfold as it should, and can affect the entire heat release/cooling process, resulting in the need for air conditioning repair. Compressors are complex, so repairs should always be conducted by trained professionals, like the ones at Shaw’s Air Conditioning.

Common Compressor Problems

  • Electrical issues – the compressor has wiring, capacitors and valves, and all can develop issues such as fraying, corrosion or disconnections. This can result in uneven electrical flow to the compressor (or even a lack of electricity), which will result in malfunction or breakdown.
  • Low refrigerant – low refrigerant in your system is almost always the result of a leak, and it can have a serious impact on how your compressor operates. The compressor is made to pressurize an exact amount of refrigerant. When this amount decreases due to a leak, it can cause the compressor to overwork, which can lead to overheating and possible breakdown.
  • Motor issues – the compressor motor can have its own issues, such as low oil, overheating or seizing. Low oil can occur from a lack in maintenance, a leak or improper amounts administered, and overheating and seizing can be the result of multiple things, including aging. If the motor on your compressor cannot be fixed, you will need to replace the entire compressor.

One of the best ways to ensure that your compressor works as it should is to schedule bi-annual maintenance. Fall is the perfect time to have your AC tuned-up, which can help you avoid repairs. Call Shaw’s Air Conditioning today and schedule a maintenance appointment with one of our trained specialists. If you happen to need air conditioning repairs in Selma, give us a call immediately.

How Does Insulation Help with Air Conditioning?

Friday, August 15th, 2014

Contrary to popular belief, insulation does not only keep you warm in the winter. While insulating parts of a home does help to keep heat indoors in the winter, limiting its ability to move inside, it also helps to keep heat out in the summertime. Adding insulation to the attic, walls, and other areas through which unwanted heat may pass, such as the ductwork, is a great way to alleviate the costs associated with air conditioning and heating and keep your home comfortable throughout the year.

While air conditioners lower the temperature inside of a home, they cannot prevent heat from moving back indoors. Heat moves naturally from a warm area to a cooler area, and air conditioners work to do the reverse process, moving the warm air inside of your home back outdoors. As refrigerant cycles through the indoor and outdoor portions of your air conditioner, it absorbs heat at the evaporator and releases it at the outside condenser unit. However, air conditioners cannot prevent heat from entering back into the home. Only the materials used in insulation can create the proper barrier to slow the transfer of heat.

There are many different types of insulation which are either installed upon construction or retrofitted into the walls. Some types of insulation have a reflective surface that reflects heat away from the home. Other forms of insulation are made out of fiberglass, wool, natural fibers, or foam materials. If you are adding insulation to a home that has already been built, a technician can blow insulation into place through a hole in the wall using special equipment.

Any form of insulation keeps heat from having a negative impact on the efficiency of your air conditioner. Improper insulation may result in uneven temperatures throughout the home, causing your AC to work harder and run for longer periods of time to keep up. A well-insulated room will not require as much energy to stay cool, saving you money every month.

Adding insulation is one of the best ways to upgrade your home and save money on air conditioning. Call the professionals at Shaw’s Air Conditioning for upgrades and more on air conditioning services in Lemoore, CA.

Noises that Indicate the Need for Air Conditioning Repair

Friday, August 8th, 2014

Odd sounds are the best “early warning system” that air conditioners have when it comes to repair needs. Unusual noises emanating from the cabinets of an AC usually mean you should call up professionals and arrange for repair work—before the cooling system faces worse problems and even suffers a breakdown.

Here are some of the more common noises that indicate the need for repairs and what they might mean. Do not, however, attempt to do any diagnosis yourself: repair technicians will track down the specific issues and address them.

For fast and skilled AC repair service in Sanger, contact Shaw’s Air Conditioning. We have 24-hour emergency service available so you will never need to spend long with a malfunctioning air conditioner.

Here Are Some Warning Signs of Air Conditioning Repairs

  • Humming: If you notice an electronic humming sound coming from either the indoor or outdoor cabinet, it might mean that one of the motors is struggling to turn on. The cause of this is often a failed capacitor. A motor that is making the humming sound is at risk of burning out, which can lead to an expensive repair, so call up technicians right away to replace the capacitors.
  • Hissing: A noise that sounds like steam escaping from a pipe is refrigerant leaking out of the system. This is a serious issue, since it will lead to a drop in cooling power and possibly an overheated compressor. The escaping refrigerant is also unhealthy to breathe. Call for repairs to locate and seal the leak, then recharge the lost refrigerant to its proper level.
  • Grinding, screeching: This is usually an over-stressed motor close to burning out. The motor may be overly dirty or has lost lubrication, triggering these unpleasant mechanical sounds. The noise could also come from a dying compressor, and this is one of the most urgent repair problems an AC can encounter.
  • Banging, striking: There are loose mechanical parts somewhere inside the cabinet. A likely source is bent fan blades that are striking the outside fan casing, or (in older ACs) a snapped fan belt hitting other components. You need to call in repairs quickly before the loose pieces start spreading the damage around.
  • Stuttering: If the AC makes stuttering noises each time the compressor tries to turn on to start the cooling cycle, then it is “hard starting,” a situation that can have a number of different causes. An expert can determine the reason the system is hard starting and find a way to put a stop to it before the air conditioner sustains additional wear and tear.

Any unusual noise from an air conditioner needs investigation. Don’t delay in calling for help from professionals.

Shaw’s Air Conditioning is now entering its second decade serving Sanger, CA with AC repair. Look to us for the assistance you need to stay cool.

How Can a New Thermostat Help With Air Conditioning Energy Efficiency?

Friday, August 1st, 2014

While today’s air conditioners are very energy efficient, there are ways to maximize energy efficiency. One way is to upgrade your thermostat, particularly if yours is over 10 years old. Your thermostat is the instrument that controls when your air conditioner cycles, so the more accurate it is, the better for your system and energy use. Shaw’s Air Conditioning offers thermostat installment, replacement and repair, and our trained technicians will teach you how to properly use your new thermostat to ensure the best operation for your air conditioning system

Help with Energy Efficiency

There are two main ways a new thermostat can help with your air conditioner’s energy efficiency:


Dial and slide thermostats are not very precise; in fact, many list degree settings in groups of 5, such as 60-65, etc. A digital manual or programmable thermostat lets you set a precise temperature, helping reduce energy waste that can come when using less precise thermostats that can consistently be 2-3 degrees off.


A programmable thermostat allows you to schedule your cooling in a 7-day, looping program in which you can accommodate for occupancy and different times of day (such as daytime and nighttime temperatures). A programmable thermostat saves energy because it cycles only when you program it to do so.

Other reasons to consider upgrading to a new thermostat include: better comfort, easier operation, easy to read, convenience and the opportunity to place your thermostat in a better spot should it be poorly placed.

Why Use a Professional?

Your thermostat is an important instrument and, if installed incorrectly, can wreak havoc on your system and compromise your indoor comfort. This is why it’s best to schedule your installation with a trained professional.

Looking for Better Energy Efficiency? Start with Your Thermostat

There are a number of ways to help your air conditioning system achieve maximum energy efficiency, but one of the easiest is upgrading your thermostat. Shaw’s Air Conditioning experts can help you select a thermostat that best fits your air conditioner and your needs, and then install and teach you how to use it. If you think it’s time to upgrade your thermostat, call us and schedule air conditioning installation service in Lemoore with our experts today.
