Air Conditioning FAQ: What Is the Compressor?

Monday, September 29th, 2014

Of the many components that make up a modern air conditioner, the compressor is the true “heart” of the system. Its function is, in many ways, similar to the heart inside a body. Without a working compressor, you don’t have a working air conditioner.

Making sure that the compressor in the AC that cools down your home works at its best and without excessive wear is one of the most important parts of regular maintenance. A failed compressor needs to be replaced, which is often the most expensive repair an air conditioner might need; in most cases of a burned-out compressor, it is more cost-effective to replace the complete cooling system.

If you need maintenance or repairs to keep the compressor in your air conditioning in Sinton, TX running, call your local AC experts at Justice Air Conditioning & Heating.

Compressor basics

The compressor is housed in the outdoor condenser unit of an air conditioner, where it is connected to a motor. The motor runs the pump action of the compressor that allows it to do its job, which is to compress the refrigerant in the system and change it into a hot, high-pressure gas. This is one of the essential steps of the heat exchange process of the air conditioner that allows the system to remove heat from inside a home and exhaust it to the outside.

Basically, it is the compressor that gives energy to the refrigerant that propels it around the air conditioner. When the refrigerant enters the compressor, it is in liquid state after having passed through the evaporator coil indoors. In order for the heat exchange cycle to continue, the refrigerant must increase in heat and pressure. The compressor, by reducing the volume available to the liquid refrigerant, raises its pressure and turns it into a hot gas. This gaseous refrigerant then moves to the next area of low pressure, which is the outdoor coil, and there it releases its heat, and continues to the indoor coil.

Without a working compressor, the refrigerant will not cycle through the system, and it will not go through the important temperature changes necessary for it to absorb and release heat. If the compressor in an AC breaks down, the system will be nothing more than a set of fans blowing around room-temperature air.

If your air conditioner begins to “hard-start,” struggling to come on and making grinding or clicking noises as the compressor starts, you will need to call for air conditioner repair technicians right away: this stress could inflict irreparable damage to the compressor. Any time your AC shows signs of losing its cooling ability could also mean there are compressor issues, so do not hesitate to contact Sinton, TX air conditioning experts like those at Justice Air Conditioning & Heating. We have technicians ready 24 hours a day to assist you.

How a New Thermostat Can Save You Money

Monday, September 22nd, 2014

Your home may have a modern HVAC system that promises top-of-the-line efficiency, but your thermostat may be the reason you’re spending more on heating and air conditioning than you should. Many older thermostats are manual, meaning you have to use sliders and dials to set the temperature to your preference. But newer programmable thermostats have advanced settings and greater accuracy, which not only helps you to stay comfortable, but can bring significant savings every month. Here are some of the ways installing a new programmable, wireless, or smart thermostat can save you money over time.

  • Accuracy: It can be difficult to tell whether the dial or slider on your thermostat is set to the proper temperature, so many homeowners are content to set the thermostat to whatever feels closest to the desired setting. But if you want your home air conditioned to 70 degrees and you have to overcompensate by setting it to 68 instead, you may spend significantly more than you need to on cooling costs. A digital display is far more accurate so you can ensure you get exactly the cooling or heating power you need.
  • Settings: With a manual thermostat, you may end up keeping your air conditioning or heating system on throughout the day when you leave the house, so that you’re greeted by a comfortable home when you arrive. But with a programmable thermostat, you can set the temperature ahead of time without having to leave it on the entire day. For example, if you know you won’t be home until late afternoon, you can set the thermostat to activate a half hour before you come home so you won’t spend money running your unit all day long.
  • Advanced Features: The newest innovation in thermostats is the smart thermostat. You can control your smart thermostat from your smart phone or from any computer with internet access. This can save you even more, allowing you to adjust the temperature as needed throughout the day even from a remote location.

Services That Can Improve Commercial Indoor Air Quality

Monday, September 15th, 2014

The heavy insulation on commercial buildings today forms a superb heat seal that helps boost energy savings. But this seal also traps dust, dirt, and other contaminants inside buildings, where they continue to circulate and accumulate, leading to a decline in the air quality in business structures.

With low indoor air quality developing into a major problem in the U.S. today, you have probably wondered what methods you can use to improve the air inside your workplace for the comfort and health of your employees, customer, and/or clients. Justice Air Conditioning & Heating offers a number of useful services that will help you improve the quality of your building’s air, as well as assist you with receiving superior efficiency from the HVAC system, resulting in lower bills.

Contact us today to learn more details about our services for commercial indoor air quality in Alice, TX and the surrounding areas.

Some of our services for commercial indoor air quality

  • Duct cleaning: The ventilation system in a building will eventually become a major repository of debris that circulates through the building. Over the space of two years, enough dust and dirt can accrue inside the ductwork to have a significant negative impact on the building’s air. Professional duct cleaners equipped with high-pressure industrial vacuums and agitation tools can thoroughly clean out this source of contamination and raise the air quality.
  • Air purifiers: A number of different installations fall under the general heading of “air purifiers.” There are mechanical filters, such as HEPA filters, that trap airborne pollutants and keep them from entering the working spaces. Electronic air purifiers use ionization of contaminating particles to draw them down to plates. Mechanical filters are a less expensive option, but they are not as thorough and do not affect all particles. Consult with an indoor air quality specialist to find out what type of filter or purifier will benefit your business the most.
  • Dehumidifiers: Humidity is one of the principal enemies of comfort inside a building. But high humidity will not only make a workplace feel stuffier and hotter; it will also contribute to water damage and the growth of molds that can have a major impact on the healthiness of the air. Commercial dehumidifiers are an excellent way to balance humidity for comfort and for better indoor air quality.

It is often difficult to know exactly what type of pollutant you need to deal with inside a building; that is why you should call on professionals experienced with indoor air quality in Alice, TX.

Justice Air Conditioning & Heating has specialists who will pinpoint where you need help for better air in your commercial building, and then provide the solutions.

Don’t Use Duct Tape

Rules of thumb can be downright problematic for homeowners because they can create more problems than they solve. When it comes to ductwork, one common rule of thumb is “just use duct tape.” Yes, the word “duct” in both “ductwork” and “duct tape” can be misleading and indicate a relationship between the two, but the truth is that duct tape is a poor choice with which to seal your ductwork. Why? There are a couple of reasons: first, duct tape will not properly adhere to your ductwork, so it is, at best, a temporary solution. Second, the glue from the duct tape will break down, rendering the tape useless and potentially making the area around the tape sticky and messy. Bottom line: duct tape is not a good choice when sealing your ductwork.

What Professionals Use

Your technician will use two key products during duct sealing: mastic, which is a fibrous adhesive that hardens into a permanent seal, and professional tape that is either fiberglass or foil. Before any sealing begins, the technician will inspect your entire ductwork system to review all areas that need sealing. Once the technician understands which areas need sealing, he/she will brush mastic on the cracks and holes, place a piece of tape on top of the mastic, then allow the mastic to dry, creating a permanent seal. For sections that need binding, the ends will be brushed with mastic, a sheet metal binding will be placed around the section, and the binding will be secured with sheet metal nails.

Duct sealing in Portland is an important step toward increasing your indoor air quality and comfort, and maintaining your ductwork for the long-term; don’t trust this to a roll of duct tape.Instead, call the professionals you can trust: Justice Air Conditioning & Heating.

The History of Labor Day

Monday, September 1st, 2014

The official end of summer and the beginning of fall lands on September 23rd, which marks the Autumnal Equinox, when the plane of the Earth’s equator passes the center of the sun and the length of day and night are roughly equal. However, for most people in the U.S., the summer really concludes with Labor Day, the first Monday in September. Labor Day and Memorial Day (the last Monday of May) together serve as the bookends of the summer.

The Labor Day Holiday is a time that people in this country associate with a last summer blast: another reason for an outdoor picnic, a chance for a three-day vacation, family trips to amusement parks, and of course, taking advantage of numerous sales that retailers always offer. (Labor Day is often the second largest shopping day of the year after Black Friday in November.) It’s also the point when school traditionally goes back in session, although some schools start a week earlier and some a week later.

Labor Day’s origins lie in the 1880s. In 1882 Matthew Maguire, a machinist in New York City who was secretary of the Central Labor Union (CLU) at the time, and Peter J McGuire of the American Federation of Labor (AFL), first proposed a celebration of the hard working men and women of the United States. However, five years would pass before the first state made it an official holiday, Oregon. Other states quickly followed this example, although not all selected a date in September.

By 1894, thirty states had started Labor Day celebrations. President Grover Cleveland signed the law that made Labor Day a federal holiday only a week after Congress voted unanimously to approve the legislation. The date chosen for the holiday was the same one that Maguire and McGuire had originally proposed.

The U.S.A. is not the only country that celebrate Labor Day on the first Monday of September. Canada observes the holiday as well, although they spell it “Labour” Day. In fact, Canada celebrated the occasion earlier than the U.S., and was an early inspiration in this country for the development of the holiday.

All of us here at Justice Air Conditioning & Heating hope you and your family—whether at work or at play—enjoy a relaxing and memorable Labor Day weekend and have a fantastic start to the fall.
