EMERGENCY: Cooling Centers Open In Los Angeles County

Looks like it's going to be triple digit temperatures for the next several days. Everyone needs air conditioning in Los Angeles and the San Fernando Valley this week.

Check on family and neighbors. Obviously don't leave anything living in a hot car. You wouldn't leave children or pets in the car anyway, would you?

If you plan to be outdoors, please take precautions to protect yourself from the sun and heat

• Avoid the sun from 10 a.m. to 3 p.m. when the burning rays are strongest. 
• Reduce physical activity
• Wear a wide - brimmed hat and light colored lightweight, loose - fitting clothes when you are outdoors 
• Avoid hot, heavy meals that include proteins
• Set your air conditioner between 75 ° to 80 °
• If you don’t have air - conditioning take a cool shower twice a day and visit a public air conditioned facility
• Drink plenty of fluids even if you are not thirsty
• Avoid alcohol 
• Use sun screen with a sun protection factor of at least 15 if you need to be in the sun
•  Symptoms of dehydration and heat cramps include dizziness, fatigue, faintness, headaches, muscle cramps and increased thirst 

During times of unbearable heat Los Angeles County provides cooling centers. Air conditioned spots that people can go to and cool off. Click here for a list of COOLING CENTERS

How Much Does Air Conditioning Ducting Cost?

"Some rooms are working and some aren't."

There is a proper use for this kind of duct. But this isn't it.

Wondering how much air conditioning ductwork costs? It could cost you your whole system if it is not installed properly. After twenty five years of repairing, installing and inspecting heating and air conditioning systems I have seen some crazy installations that have ruined the energy efficiency of perfectly good air conditioning equipment.

"My air conditioning is not blowing."

Mold can cause lasting health problems

The best thing to do when your air conditioner is not working is to call a licensed and insured air conditioning contractor. They should be certified by the EPA. They will know the correct duct to use for different applications and how to install it correctly. Improperly installed ducting is an energy waster at best. Badly installed ducting can allow toxic mold into your home or stress your HVAC equipment enough to cause mechanical failure.

Don't trust your HVAC ducting repair or installation to an unlicensed handyman or your friend who has a tool-belt. Your air conditioning system is an valuable investment for your home. Properly installed ducting is an investment in the indoor air quality of your home and the health and safety of your family.

How the Ban on Ozone-Depleting Refrigerants Effects You

What You Need To Know About New R-22 Freon Laws

This year, 2013, is the first year that there will not be enough R-22 refrigerant produced to meet residential demand. You and I both know that when supply tightens up prices rise. Freon is already expensive. So plan on prices rising this summer and over the coming years.

Ozone-depleting R-22 Refrigerant

But terms like R-22 are a little technical, let me explain; R-22 has been the refrigerant of choice for residential heat pump and air-conditioning systems for more than four decades. Unfortunately for the environment, R-22 contributes to ozone depletion. In addition, R-22 is a greenhouse gas that contributes significantly to global warming.

What is being done to keep us cool? 

As R-22 is phased out over the coming years manufacturers of residential air conditioning systems are offering equipment that uses ozone-friendly refrigerants. Many homeowners may be misinformed about how much longer R-22 will be available to service their central A/C systems and heat pumps. Homeowners need information about the transition  when deciding whether to purchase a new A/C system or heat pump, or when having an existing system repaired.

Existing units using R-22 can continue to be serviced with R-22. There is no EPA requirement for homeowners to change or convert R-22 units for use with a non-ozone-depleting substitute refrigerant.

New refrigerants have been developed and many companies are using them to replace R-22 in existing systems. Such changes, called "retrofits," are allowed if the alternative has been found acceptable for that type of use.

Air Conditioning Contractor, Dean Gilford, provides training for his EPA certified service technicians

WARNING: Use a reputable Air Conditioning contractor

One important thing a homeowner can do for the environment, regardless of the refrigerant used, is to select a reputable dealer that employs service technicians who are EPA-certified to handle refrigerants. Technicians often call this certification "Section 608 certification," referring to the part of the Clean Air Act that requires minimizing releases of ozone-depleting chemicals from HVAC equipment.

A Reputable Air Conditioning Contractor will take the time to learn and train their service technicians how to properly retrofit an air conditioning system with ozone friendly refrigerant.

"We are seeing terrible disservices done to homeowners," says Dean Gilford, owner of Kilowatt Heating, Air Conditioning & Electrical. "Service techs pumping the less expensive newer refrigerant into a unit without taking the existing R-22 out first!"

There are steps that need to be taken and a specific way these retrofits need to be handled so extra training is required to be able to properly provide new safer refrigerant.

If your home is located in Los Angeles or San Fernando Valley there are technicians trained in the replacement of R-22 and they can be reached by calling 818-780-0701.

Proper Sizing of Central Air Conditioning

Whether you are looking to install a new central air conditioning unit or replacing a current unit, it is important to use the correct size unit. A that is too small will run continuously without adequately cooling the house, while a unit that is too big is overly costly and, due to frequent on/off cycles, can cause humidity problems.

Proper System Sizing 

In order to scientifically calculate the right central air conditioner size, you can perform a Residential Load Calculation. The sizing chart above is useful to help you determine your approximate central air conditioner size requirements.

Another way to size replacement air conditioners is to determine the system size that is currently in place. The manufacturers do not list the air conditioner size on the unit. The system capacity will be coded into the model number of the outdoor unit. For example, model CKL24-1 is a 2 ton unit.
Why? There are 12,000 Btu's per ton. The number 24 in the model number indicates the unit is 24,000 Btu's, divided by 12,000 Btu's per ton, equals 2 tons. 24,000 Btu's/12,000 Btu's per ton = 2 tons Use the following conversion information to determine your existing system size (use the system model number NOT the serial number) 18 = 1.5 tons 24 = 2 tons 30 = 2.5 tons 36 = 3 tons 42 = 3.5 tons 48 = 4 tons 60 = 5 tons.

When sizing air conditioners, be careful not to make the mistake of getting one that is too large. If the system you install is too large for the space, it will short cycle. In other words, the compressor will not run long enough to dehumidify the space and will limit your comfort. In addition, it will cycle on and off more frequently, increasing operating costs and reducing the system life.

Insulation Variables Variables such as your insulation, type and number of windows, number of stories, construction type, etc. will greatly affect the required Btu's per square for both heating and cooling. A general rule of thumb is that if your home is well insulated with newer style windows, you can select the smaller size system that falls within your total square footage.

If your home is two story it will place less of a load on the system in the downstairs area as the second floor acts as additional insulation. If your home is not well insulated, has older style windows, and/or a larger than average number of windows, you will want to select the larger system which falls within your square footage range. The less insulated and more windows within the environment, the more likely you will experience greater air and heat loss.

Proper air conditioner sizing is critical to optimize performance.

Can next-gen building materials cut HVAC?

What if your building could regulate it's own temperature?

Smart-building materials have come a long way in the last decade: They're less toxic, more durable and more energy efficient than their predecessors. But the smartest materials available today still can't accomplish something that even the most primitive life forms can do -- keep their internal environment stable as outside conditions change.
It's called homeostasis. Healthy humans, for example, maintain body heat of about 98.6 degrees as outside temperatures vary, manage their oxygen and carbon-dioxide levels and also keep their blood pressures, salt and sugar contents from falling too low or climbing too high. Even amoebas maintain their osmotic pressure at a livable rate. And cells in all living organisms manage their levels of ATP, the substance that enables the production and flow of energy internally from one set of biochemical reactions to another.
"If you look at living organisms, one of the most basic things they can all do is regulate their own internal conditions," says Ximin He, a post-doctorate fellow at the Harvard School of Engineering and Applied Science and the Hansjorg Wyss Institute for Biologically Inspired Engineering. "It's how organisms survive in different seasons and face the constant challenges life throws at them," she says.
Now researchers at Harvard University and the University of Pittsburgh hope to create a new class of materials that can do the same thing. After about two years of research, the scientists have come up with a platform for creating materials that can self-regulate many different factors, including temperature, light, pressure or pH balance. And they've already invented one prototype: a thin water-based gel, or hydrogel, that automatically heats up when it's cold (and stops heating when it isn't) to maintain a constant temperature.
The research, unveiled in Nature in July, could have huge implications for smart buildings in Los Angeles. If future building materials could control their own temperatures, they might be able to eliminate the need for air conditioning and heating. Given that buildings account for nearly 39 percent of the U.S. energy use -- and heating, ventilation and air conditioning make up 64 percent of that 39 percent -- such a feat could significantly cut energy consumption and greenhouse-gas emissions.
It could also win these materials a piece of the booming sustainable-building market. Santa Monica, Calif.-based research firm IBISWorld expects the U.S. market will total $20.6 billion this year, up 7.3 percent from 2007, and reach $45.2 billion in five years.

How to Combat Heat Stress

Adequate hydration is the most important step to combating heat stress. When the heat index is high, stay properly hydrated. Don't wait until you feel thirsty to drink; if you are thirsty you may already have lost 2% of your body's water. The onset of heat exhaustion can begin after losing 3% of the body's water and heat stroke occurs once 8% is lost.

WARNING SIGN: If you are not urinating regularly or have dark urine, you may be dehydrated and at risk for heat illnesses!

Rest in a cool environment. Take fluids and salty foods or an electrolyte solution such as sports drinks.

Los Angeles Opens Emergency Cooling Centers

To provide relief from the heat for the elderly and others who face heat-related health difficulties and stress, the Los Angeles County Department of Public Health will open cooling centers throughout Los Angeles County, announced Supervisor Michael D. Antonovich. A list of the location and times of operation of the 55 cooling stations in Los AngelesCounty can be accessed by dialing 2-1-1.

Symptoms of dehydration and heat cramps include dizziness, fatigue, faintness, headaches, muscle cramps, and increased thirst.

The Department of Public Health recommends several ways to manage the heat:

• Never leave children, elderly people, or pets alone in a parked vehicle.
• Wear light, loose fitting clothing to stay cool
• Drink water often. Avoid drinking alcohol.
• Check on those in your neighborhood who have limited mobility.
• Stay in an air-conditioned area during peak heat hours such as a mall, park, or library.
• Avoid unnecessary sun exposure. When in the sun, wear a hat, preferably with a wide brim.
• Don’t exercise vigorously outside during the hottest hours of the day

Always use a licensed and insured Air Conditioning Contractor in Los Angeles.
