Benefits of the CFC Phase-Out- Los Angeles Air Conditioning

Benefits of the CFC Phase-out

The CFC phase out is already producing benefits for the environment, businesses, and inpiduals. This fact sheet explains some of these benefits. Several case studies of successful conversions to alternatives are listed also. Los Angeles Air Conditioning experts like to keep you up to date on all the latest information. If you ever have any questions about heating or LA air conditioning feel free to give American Air Conditioning a call to day at +1 (800) 321-9494.

Protection of the Ozone Layer

The chlorofluorocarbon (CFC) production phase out is an important turning point in the recovery of the ozone layer. Currently, we are experiencing depletion of approximately 5 percent at mid-latitudes, but if no action had been taken to limit CFCs, ozone depletion at mid-latitudes would eventually have reached 20 percent or more.

Because of the phase out, CFCs are no longer accumulating in the atmosphere at an accelerating rate. Scientists predict that maximum CFC levels will occur before the turn of the century. If international agreements are adhered to, the ozone layer is expected to recover around 2050. Much more information on the science of ozone depletion is available online.

Reduced Health Risks

The phase out of CFCs is expected to have direct health benefits over the next century, including reduced incidence of skin cancer and cataracts, decreased risks to human immune systems, and increased protection of plant and animal life from excessive UV exposure. A United Nations Environment Programmer (UNEP) study shows that a sustained 1 percent decrease in stratospheric ozone will result in about a 2 percent increase in the incidence of non-melanoma skin cancer, which can be fatal. With the successful phase out of CFCs, however, EPA expects 295 million fewer cases of this form of skin cancer over the next century.

New Technologies - Los Angeles Air Conditioning

The CFC phase out prompted research into alternative methods for cleaning applications in electronic assemblies and precision parts. Users often found that the need for chemicals during cleaning processes was reduced or even eliminated, while maintaining product quality and reducing costs. Precision ball bearings, medical devices, and sophisticated electronics components are now being produced using aqueous cleaning. New "no-clean" technologies eliminate the cleaning process altogether for printed circuit boards.

Energy Savings - Los Angeles Air Conditioning

The CFC phase out provided an impetus to develop and invest in a new generation of energy efficient air-conditioning and refrigeration equipment. Electric utilities have acknowledged this benefit by providing financial incentives for installing energy-efficient equipment. Aside from substantial lifetime energy and dollar savings, equipment upgrades also improve occupant comfort, system reliability, and operation and maintenance.

The Air Conditioning and Refrigeration Institute (ARI) reports that by 1998, 44 percent of existing chillers (large scale air conditioning units for buildings) will be converted or replaced with equipment that uses non-CFC refrigerants. This conversion to more efficient equipment is anticipated to reduce energy use by almost 7 billion kilowatt hours per year, amounting to $480 million annual savings for new equipment owners by January 1998.

Pollution Prevention - LA AC

The energy savings from equipment upgrades mean that less fossil fuels are burned at the power plant, leading to reduced emissions of air pollutants including carbon dioxide (CO2), nitrogen oxides (NOx), and sulfur dioxide (SO2). These pollutants are responsible for global warming and acid rain. By 1998, chiller conversions and replacements are estimated to avoid emissions of 4 million tons of CO2, and 34,000 tons of SO2. The reduction in SO2 represents the annual emissions of one and a half large coal-fired power plants.

Los Angeles AC Condensers

Los Angeles AC condensers are essential to central Los Angeles air conditioning systems. An LA AC condenser unit will usually consist of a heat exchanger, a compressor and a fan. The heat exchanger cools and condenses the incoming refrigerant vapor into liquid, the compressor raises the pressure of the refrigerant and forces it to move and the fan blows the outer air through the heat exchanger. This results in a cooling of the refrigerant inside the home LA AC condenser. A central AC condenser is typically located outside the home with a layer of tubing between it and the building that ushers vapor refrigerant in and pulls liquid refrigerant out.

There are many factors that may keep home Los Angeles AC condensers from running efficiently, which can keep your home from being as cool as you want it to be and cause unnecessary expenses on your electric bill. Cleaning AC condenser units is often all it takes, which should be part of your annual maintenance service. Or if components of the system are not functioning properly, LA AC condenser repair may be necessary to make your home comfortable and energy efficient again.

AC condenser replacement may also be the best option if your unit is beyond repair or if it is unable to meet today’s energy efficiency standards. The team of skilled technicians at American Air Conditioning & Heating is prepared to replace AC condenser units for homes of all shapes and sizes in the greater Los Angeles area. We can provide detailed information about the AC condensers that are available, install the unit with the utmost professionalism and provide all the maintenance and repair services you need to keep it running smoothly and efficiently.

Is Your Home Making You Sick? - Los Angeles Air Conditioning

Los Angeles air conditioning experts thought to understand why many of today’s health problems can be caused by the home you live in, you need to look back a few years to see what caused this to happen. You see, during the energy crisis of the early 1970s, highly insulated “tight” homes became popular because of their potential to reduce energy costs.

Within a few years, however, complaints started to arise, due to health, and excessive moisture issues caused by indoor pollution, and associated moisture problems within these homes.

In the late 1980s and early 90s, indoor air quality became a nationally recognized issue. Even today, newer and more energy-efficient homes seemed predisposed to the problem. In addition, they retain more humidity and airborne pollutants, which causes longer life-spans, and more productive cycles of microbial activity within the home, such as mold, germs, bacteria and viruses.

This greater activity and concentration of these airborne contaminants, equates to more allergic reactions, and sickness within families, for longer periods of time.

MOLD: A SURVIVOR

Why is mold so difficult to control? Mold is at the bottom of the food chain. It thrives on very little, grows rapidly, and produces spores, volatile organic com-pounds, and other toxins. One organism can multiply to trillions in less than three weeks. When given the right conditions, mold can occur anywhere; in homes, schools, workplaces, entertainment centers, vehicles, etc.

The interior of your ductwork and air conditioning equipment, provides an ideal environment for mold growth — especially in the air conditioners inside drain-pan where it is dark, damp, and filled with nutrients. The result can be like blowing air over a swamp or through a sewer and then into your home, vehicle, and workplace.

According to the World Health Organization (WHO), 60% of Indoor Air Quality (IAQ) problems and allergies may be mold-related. Some IAQ diagnosticians and practitioners today say the figure may be as high as 80%. The increased usage of air conditioning systems almost directly parallels the increase of allergies and IAQ problems.

As mold and bacteria grow on coils and in drain pans, they are disseminated through the ducts to occupied spaces. Some mold products (toxins) produce serious and sometimes life-threatening reactions, including allergy, asthma, hypersensitivity, pneumonitis, and in some extreme cases even bleeding lung disease.

Additionally, mold creates a troublesome maintenance problem. Its activity results in dirty coils, a loss of air-flow, loss of heat exchange efficiency, dirty and sometimes plugged drain pans, and excessive energy use.

USING UVC TECHNOLOGY

Los Angeles AC experts have found that the most successful way to handle system mold is through Ultraviolet (U.V.) germicidal lights. These U.V. systems are a recent breakthrough in protecting the health of a home.

Ultraviolet light in the “C" band (UVC) has been used for more than 65 years to kill microorganisms in hospitals, barber shops, laboratories, pharmaceutical plants, and at the nation's Center for Disease Control. Residential ultraviolet units have been independently tested and proved to be effective in the constantly moving air environments of heating and cooling systems, killing mold and bacteria quickly and effectively. The UVC energy attacks the organism’s DNA and either destroys it immediately or prevents it from reproducing.

For most people, the original motivation for installing the lights is to abate IAQ complaints and/or allergies. However, they are also pleased to learn that many hidden odors are also eliminated with U.V. technology. Los Angeles Air Conditioning

Hot Water Costs & Cost-Cutters - Los Angeles Air Conditioning

Your Los Angeles air conditioning experts, American Air Conditioning & Heating are here to give you tips on managing and saving money in every aspect of your home. Some ways to save on water-heating bills require greater financial investments than others. You may wish to consider the no- or low-cost options before making large purchases. Also allow for circumstances that may be unique to your household when deciding on the appropriate options (e.g., a small-capacity washing machine could meet the needs of a one person household efficiently). Although it is not feasible to eliminate water heating in your home, it is possible to substantially reduce water-heating costs without sacrificing comfort and convenience. We want to save money on Los Angeles AC and every other aspect of your home that uses energy.

Figuring out how much you spend to heat your water:

The next time you pay your Los Angeles air conditioning utility bill, try one simple calculation. Divide the total amount by seven. The result is the amount you spend to heat your water. (If you receive separate utility bills for gas and electricity, use the gas bill for this calculation if you have a gas water heater; use the electric bill if you have an electric water heater.)

Of course, you may think this cost is a small price to pay for the convenience of a hot shower. But during the course of a year, this cost adds up. And when you consider that 95 million households in this country pay the same percentage, it is easy to see how much money—and energy—is used to heat water.

Several measures can help you decrease water-heating costs in your home. Some specific actions include reducing the amount of hot water used, making your water-heating system more energy efficient, and using off-peak power to heat water.

Reducing the amount of hot water used:

Generally, four destination points in the home are recognized as end uses for hot water: faucets, showers, dishwashers, and washing machines. Now, you do not have to take cold showers, dine on dirty dishes, or wear dirty clothes to reduce your hotwater consumption. Less radical measures are available that will be virtually unnoticeable once you apply them.

Faucets and Showers:

Simply repairing leaks in faucets and showers can save hot water. A leak of one drip per second can cost $1 per month, yet could be repaired in a few minutes for less than that. And some apparently insignificant steps, when practiced routinely at your household, could have significant results. For example, turning the hot-water faucet off while shaving or brushing your teeth, as opposed to letting the water run, can also reduce water-heating costs. Another option is limiting the amount of time you spend in the shower. Other actions may require a small investment of time and money. Installing low-flow showerheads and faucet aerators can save significant amounts of hot water. Low-flow showerheads can reduce hot water consumption for bathing by 30%, yet still provide a strong, invigorating spray.

Faucet aerators, when applied in commercial and multifamily buildings where water is constantly circulated, can also reduce water-heating energy consumption. Older showerheads deliver 4 to 5 gallons (15.1 to 18.9 liters) of water per minute. Although a low-flow showerhead delivers slightly less water than a standard showerhead, the spray can still be invigorating.
[FS 204 January 1995] sets maximum water flow rates at 2.5 gallons (9.5 liters) per minute at a standard residential water pressure of 80 pounds per square inch (552 kilopascals).

A quick test can help you determine if your shower is a good candidate for a showerhead replacement: Turn on the shower to the normal pressure you use, hold a bucket that has been marked in gallon increments under the spray, and time how many seconds it takes to fill the bucket to the 1-gallon (3.8-liter) mark. If it takes less than 20 seconds, you could benefit from a low-flow showerhead. A top quality, low-flow showerhead will cost $10 to $20 and pay for itself in energy saved within 4 months. Lower quality showerheads may simply restrict water flow, which often results in poor performance. You will have more money during the summer to run that Los Angeles air conditioning system!

Because of the different uses of bathroom and kitchen faucets, you may need to have different water flow rates in each location. For bathroom faucets, aerators that deliver 0.5 to 1 gallon (1.9 to 3.8 liters) of water per minute may be sufficient. Kitchen faucets may require a higher flow rate of 2 to 4 gallons (7.6 to 15.1 liters) per minute if you regularly fill the sink for washing dishes. On the other hand, if you tend to let the water run when washing dishes, the lower flow rate of 0.5 to 1 gallon per minute may be more appropriate. Some aerators come with shut-off valves that allow you to stop the flow of water without affecting the temperature.

Automatic Dishwashers:

A relatively common assumption is that washing dishes by hand saves hot water. However, washing dishes by hand several times a day could be more expensive than operating some automatic dishwashers. If properly used, an efficient dishwasher can consume less energy than washing dishes by hand, particularly when you only operate the dishwasher with full loads.

The biggest cost of operating a dishwasher comes from the energy required to heat the water before it ever makes it to the machine. Heating water for an automatic dishwasher can represent about 80% of the energy required to run this appliance. Average dishwashers use 8 to 14 gallons (30.3 to 53 liters) of water for a complete wash cycle and require a water temperature of 140°F (60°C) for optimum cleaning.

But, setting your water heater so high could result in excessive standby heat loss. This type of heat loss occurs because water is constantly heated in the storage tank, even when no hot water is used. Furthermore, a water heater temperature of 120°F (48.9°C) is sufficient for other uses of hot water in the home. The question, then, is must you give up effective cleaning for hot water energy savings? The answer is no.

A “booster” heater can increase the temperature of the water entering the dishwasher to the 140°F recommended for cleaning. Some dishwashers have built-in boosters that will automatically raise the water temperature, while others require manual selection before the wash cycle begins. A booster heater can add about $30 to the cost of a new dishwasher but should pay for itself in water-heating energy savings in about 1 year if you also lower your water heater temperature. Reducing the water heater temperature is not advisable, however, if your dishwasher does not have a booster heater.

Another feature that reduces hot-water use in dishwashers is the availability of cycle selections. Shorter cycles require less water, thereby reducing the energy cost. The most efficient dishwasher currently on the market can cost half as much to operate as the most inefficient model.

If you are planning to purchase a new dishwasher, check the EnergyGuide labels and compare the approximate yearly energy costs among brands. Dishwashers fall into one of two categories—compact capacity or standard capacity. Although compact capacity dishwashers may appear to be more energy efficient, they hold fewer dishes and may force you to use the appliance more frequently than you would use a standard-capacity model. In this case, your energy costs could be higher than with the standard-capacity dishwasher.

Turning the hot-water faucet off while shaving or brushing your teeth, as opposed to letting the water run, can reduce water-heating costs. An efficient automatic dishwasher can consume less energy than washing dishes by hand, particularly when you only operate the dishwasher with full loads.

Washing Machines:

Like dishwashers, much of the cost—up to 90%—of operating washing machines is associated with the energy needed to heat the water. Unlike dishwashers, washing machines do not require a minimum temperature for optimum cleaning. Either cold or warm water can be used for washing most laundry loads; cold water is always sufficient for rinsing. Make sure you follow the cold-water washing instructions for your particular laundry detergent. Washing only full loads is another good rule of thumb for reducing hot-water consumption in clothes washers. As you would for dishwashers, consult the EnergyGuide labels when shopping for a new washing machine. Inefficient washing machines can cost three times as much to operate as efficient machines. Select a machine that allows you to adjust the water temperature and water levels for the size of the load. Also, front-loading machines use less water and, consequently, less energy than top loaders.

However, in this country, front loaders are not as widely available as top loaders. Keep in mind that the capacity of front loaders may be smaller than that of most top-loading machines.

Smaller capacity washing machines often have better EnergyGuide ratings. However, a reduced capacity might cause you to increase the number of loads you wash and possibly increase your energy costs.

Faucets, shower heads, dishwashers, and washing machines are only destination points for hot water in your home. The journey of your hot water before it reaches these outlets can be fraught with opportunities for energy losses. Fortunately, you can reduce the incidence of water heat loss from the point of departure to the point of arrival by applying a few basic measures.

Thermostats and Control Systems- Los Angeles Air Conditioning

You can save around 10% a year on your Los Angeles Air Conditioning heating and cooling bills by simply turning your thermostat back 10°–15° for eight hours. You can do this automatically without sacrificing comfort by installing an automatic setback or programmable thermostat for your Los Angeles Air Conditioning system.

A programmable thermostat offers a lot of flexibility in its temperature settings.

Using a programmable thermostat, you can adjust the times you turn on the LA heating or LA air-conditioning according to a pre-set schedule. As a result, you don't operate the equipment as much when you are asleep or when the house is not occupied.

Programmable thermostats can store and repeat multiple daily settings (six or more temperature settings a day) that you can manually override without affecting the rest of the daily or weekly program. When shopping for a programmable thermostat, be sure to look for the ENERGY STAR label.

General Thermostat Operation

You can easily save energy in the winter by setting the thermostat to 68°F while you're awake and setting it lower while you're asleep or away from home. By turning your thermostat back 10°–15° for 8 hours, you can save about 5%–15% a year on your heating bill—a savings of as much as 1% for each degree if the setback period is eight hours long. The percentage of savings from setback is greater for buildings in milder climates than for those in more severe climates.

In the summer, you can follow the same strategy with central LA air conditioning, too, by keeping your house warmer than normal when you are away, and lowering the thermostat setting to 78°F (26°C) only when you are at home and need cooling. Although thermostats can be adjusted manually, programmable thermostats will avoid any discomfort by returning temperatures to normal as you wake or return home.

A common misconception associated with thermostats is that a furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings. This misconception has been dispelled by years of research and numerous studies. The fuel required to reheat a building to a comfortable temperature is roughly equal to the fuel saved as the building drops to the lower temperature. You save fuel between the time that the temperature stabilizes at the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

Limitations For Homes with Heat Pumps, Electric Resistance Heating, Steam Heat, and Radiant Floor Heating

Programmable thermostats are generally not recommended for heat pumps. In its cooling mode, a heat pump operates like an air conditioner, so turning up the thermostat (either manually or with a programmable thermostat) will save energy and money. But when a heat pump is in its heating mode, setting back its thermostat can cause the unit to operate inefficiently, thereby canceling out any savings achieved by lowering the temperature setting. Maintaining a moderate setting is the most cost-effective practice. Recently, however, some companies have begun selling specially designed programmable thermostats for heat pumps, which make setting back the thermostat cost effective. These thermostats typically use special algorithms to minimize the use of backup electric resistance heat systems.

Electric resistance systems, such as electric baseboard heating, require thermostats capable of directly controlling 120-volt or 240-volt circuits. Only a few companies manufacture line-voltage programmable thermostats.

For steam heating and radiant floor heating systems, the problem is their slow response time: both types of systems may have a response time of several hours. This leads some people to suggest that setback is inappropriate for these systems. However, some manufacturers now offer thermostats that track the performance of your heating system to determine when to turn it on in order to achieve comfortable temperatures at your programmed time.

Alternately, a normal programmable thermostat can be set to begin its cool down well before you leave or go to bed and return to its regular temperature two or three hours before you wake up or return home. This may require some guesswork at first, but with a little trial and error you can still save energy while maintaining a comfortable home.

Choosing and Programming a Programmable Thermostat

Most programmable thermostats are either digital, electromechanical, or some mixture of the two. Digital thermostats offer the most features in terms of multiple setback settings, overrides, and adjustments for daylight savings time, but may be difficult for some people to program. Electromechanical systems often involve pegs or sliding bars and are relatively simple to program.

When programming your Los Angeles Air Conditioning thermostat, consider when you normally go to sleep and wake up. If you prefer to sleep at a cooler temperature during the winter, you might want to start the temperature setback a bit ahead of the time you actually go to bed; you probably won't notice the house cooling off as you prepare for bed. Also consider the schedules of everyone in the household; is there a time during the day when the house is unoccupied for four hours or more? If so, it makes sense to adjust the temperature during those periods.

Other Considerations

The location of your thermostat can affect its performance and efficiency. Read the manufacturer's installation instructions to prevent "ghost readings" or unnecessary furnace or air conditioner cycling. Place thermostats away from direct sunlight, drafts, doorways, skylights, and windows. Also make sure your thermostat is conveniently located for programming.

Indoor Air Quality- How do molds affect people? Los Angeles Air Conditioning

Los Angeles Air Conditioning is here to inform you that indoor air quality is really important. Not everyone realizes that the quality of the air inside your house is sometimes worse than the air quality outside. Mold can be a big issue and negatively contribute to your air quality. Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Some people, such as those with serious allergies to molds, may have more severe reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath. Some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.

EPA's publication, Indoor Air Pollution: An Introduction for Health Professionals, assists health professionals (especially the primary care physician) in diagnosis of patient symptoms that could be related to an indoor air pollution problem in Los Angeles Air Conditioning. It addresses the health problems that may be caused by contaminants encountered daily in the home and office. Organized according to pollutant or pollutant groups such as environmental tobacco smoke, VOCs, biological pollutants, and sick building syndrome, this booklet lists key signs and symptoms from exposure to these pollutants, provides a diagnostic checklist and quick reference summary, and includes suggestions for remedial action. Also includes references for information contained in each section. This booklet was developed by the American Lung Association, the American Medical Association, the U.S. Consumer Product Safety Commission, and the EPA. EPA Document Reference Number 402-R-94-007, 1994. Los Angels AC

Allergic Reactions - excerpted from Indoor Air Pollution: An Introduction for Health Professionals section on: Animal Dander, Molds, Dust Mites, Other Biologicals. Los Angeles AC

"A major concern associated with exposure to biological pollutants is allergic reactions, which range from rhinitis, nasal congestion, conjunctival inflammation, and urticaria to asthma. Notable triggers for these diseases are allergens derived from house dust mites; other arthropods, including cockroaches; pets (cats, dogs, birds, rodents); molds; and protein-containing furnishings, including feathers, kapok, etc. In occupational settings, more unusual allergens (e.g., bacterial enzymes, algae) have caused asthma epidemics. Probably most proteins of non-human origin can cause asthma in a subset of any appropriately exposed population."
