In April 2009, Mayor Bloomberg signed a bill giving NYC the toughest laws against vehicular idling, with stiff fines for repeat offenders. Three months later, AP reporters caught the mayor repeatedly flouting the law, with his chauffeur and security detail sometimes leaving their engines running for an hour while waiting for the mayor. Bloomberg had to apologize, but ever since he's presumably had a team of engineers working around the clock to come up with a solution to keep his SUV cool when he's not in it. Well, they finally had a major breakthrough, and yesterday they did some beta-testing! As you can see from these photos obtained by the NY Post, they're experimenting with a high-tech solution that will enable the mayor to step into a pre-chilled, hypocrisy-free SUV. To be honest, the science at work here is beyond our primitive understanding, but to put it in layman's terms, it seems engineers have connected what appears to be a standard residential A.C. unit onto the rear window of Bloomberg's SUV.

Then, using a complicated series of "extension cords" and—no doubt—some sort of nuclear fusion, the A.C. unit will be "plugged in" to an electrical power source.how to calculate ac unit for a house At press time, it was unclear how many miles of extension cord the mayor will need to conduct official business within the five boroughs, but clearly this innovation will be an enormous boon for New York's troubled extension cord industry. through wall ac unit(Rumors that Bloomberg was sourcing the extension cords from Malaysian sweatshops could not be confirmed.) best ac unit brandsSpeaking to the Post, Bloomberg's spokesman said yesterday was just an experiment, adding that "there is far less emissions corresponding to the power of a single air conditioner on the grid than idling a V-8 engine."

And by attaching colorful plastic ribbons to the AC's vents, Bloomberg's backseat is bound to be far more festive!There's a lot of snake oil and questionable products lining the shelves of the average auto parts store. From octane booster to VTEC fluid (ha!), it's hard to separate the genuinely useful products from the chaff. So when A/C Pro sent me a few canisters of its do-it-yourself air conditioning recharge system, I was a bit skeptical. The idea is that most aging car air conditioning systems that don't blow as cold as they should suffer only from low levels of refrigerant. The way A/C Pro works is that you plug a can into your car's air conditioner and simply refill the system with R-134a refrigerant and the necessary lubricants to rejuvenate aging seals and moving parts. I've laid out detailed instructions for using the A/C Pro product in the gallery below. Check it out for photos and a full walkthrough. Putting it to the test With the car running and the air conditioning system powered on, I located the air conditioner's low side connection port.

Air conditioning systems are essentially split into two parts, the low- and high-pressure sides, and the cooling happens as the refrigerant is compressed and passes from a state of high pressure to low pressure. After locating the low-pressure connection point, I used the A/C Pro's gauge to measure the pressure of the system. (Be sure to keep your hands clear of moving parts; I got a nice friction burn on the back of my hand from a moving accessory belt.) If the pressure looks low, then it's time to refill and recharge the system using the A/C Pro product by pulling the trigger on the filler nozzle. The filler nozzle and pressure gauge combo gives feedback and control over the refilling and the user should take care not to overfill the system, which can adversely affect the system's ability to chill air. Our test car, a 1999 Toyota Corolla, was blowing 84-degrees-Fahrenheit air at the beginning of the test. I saw a 20-degree drop in vent air temperature to about 64 degrees. That's a big-enough jump to prove that the product does work -- at least as a short-term fix.

Systems with moderate to large leaks could eventually depressurize again and may still need a mechanic's help. A/C Pro tells us that for the vast majority of systems, this simple recharge should be enough. All in, prepping, measuring, and recharging the system took me about 30 minutes. However, the Corolla's pressure levels were exceptionally low and I took more time than I probably needed to measure air temperatures and take photos, so it's still a fairly quick fix. I should note that the Corolla was actually my second attempt to test the A/C Pro product. My first attempt was under the hood of a 1990s vintage Volkswagen Jetta. Unfortunately, this system had bigger problems than the A/C Pro product could fix. There's only so much that a simple refilling, recharging, and lubricating product can do. If there's physical damage (such as a seized compressor or a serious leak), you may need more help than A/C Pro can supply. Still, for only about $45 to $50 at your local auto parts retailer, A/C Pro isn't a bad DIY first step before calling in a professional (and potentially expensive) mechanic.

How to make car ac cooler? I live in Florida and it’s in the 90s. I need to make my car air conditioner colder. It is very humid outside and it feels like my car A/C is not as cold as it usually is. Is there anything in my AC that I can modify or refill? Do I need more of the stuff that makes the air colder called Freon? Maybe it is not working right and I need auto a/c repair? I had the Freon refilled or added a year ago and it didn’t seem to get any colder in my car. My car is a 2012 Ford Focus. If there is nothing I can do mechanically or to modify my AC myself, are there any tips or tricks to make the air conditioner in my car work better and get colder? (if your car ac smells bad, here is a way to make my car ac smell better)How Can I Make My Cars Air Conditioner Colder?1 – Yes there are things you can do to make your car ac colder and blow out faster. One super simple tip is to turn the ac vents going to the passenger side off. Usually there is a control wheel on each air vent that allows you to position and point the air flow.

This control wheel or slider will also allow you to shut the vent. If you shut the AC vents that go to the passenger side, you will get MORE AIRFLOW to the ac vents that are on the drivers side. This will increase and double the airflow to the drivers side.Adjust car ac vent to blow air on you2 – Park your car under some shade or use a window sun blocker. On a hot and sunny day the temperature inside a parked car can get to 145ºF. This is even if the outside temperature is only 90º to 100ºF. By blocking the sun entering the windows of your car, you will keep it cooler therefore making the ac not have to work as hard once you get in and begin your drive.Use a car sun shade in your car to keep it cool3 – Never put the pedal to the metal. When you stomp on the accelerator, you are taking away the power needed for the ac to run efficiently. Some cars use the extra acceleration you are demanding by using all power necessary therefore your ac will keep blowing air but will not be as cold.

In hot weather when running your cars ac, do not accelerate too quickly, accelerate gradually and this will keep the ac running as normal.4 – Be sure to point the ac vents directly at you. One to your head and one to your mid body. This will keep you cooler instead of leaving the ac vents just blowing straight, so position them to face you.5 – When your car has been sitting in the sun, the car will obviously be hot inside. To minimize the heat in the car and get your ac to blow cold air as fast as possible… start your cars engine, turn the blower fan to the maximum speed and then turn on the A/C by pressing the ac button. Open all the windows in your car and select OUTSIDE air mode to allow the blowing air to push the hot air out of your car and the ac system itself. After driving a minute or two and the car is aired out, close all the windows. Set the air flow to the upper and lower vents. Turn the knob to RECIRCULATE mode for maximum ac.Auto stores now sell a refrigerant that you can purchase and recharge your car ac system yourself.

It is called A/C R-134a Air Conditioning Refrigerant. These bottles of refrigerant come with a gauge so you know when your ac is fully charged. If you decide to purchase this and DIY, see the picture below to know where to add the AC refrigerant in your car.IMPORTANT INFORMATION WHEN USING AC REFRIGERANT: Your vehicle’s air conditioning system has two sides, a LOW pressure side and a HIGH pressure side. This depends on where you are standing in relation to the ac compressor. You add the refrigerant to your A/C through the LOW pressure port. Your car will have a cap over each pressure port. One cap is labeled “H” for high pressure and the other is labeled “L” for low pressure. The pressure ports are different sizes so you are unable to attach the hose to the wrong port.Where do i add refrigerant to my cars ac?1 – Be sure your heater damper door is sealed properly and does not allow heater air to be mixed with ac air.2 – If your car ac is cold but there is not enough airflow, make sure nothing got sucked up into the return air under the dashboard.

This will restrict airflow and cause your ac to not perform as designed. A plastic shopping bag or similar can get sucked in there and restrict the air therefore causing less volume of air being blown into the cars cabin.3 – Cabin air filter may be clogged up with debris. Replace it if it is dirty. (Check owners manual if you are unsure if you have one)4 – Your car may be low on R-134 refrigerant or Freon. This will cause the ac air to not be cold but the air will still blow out of the vents. If this is the case you can either DIY and buy a bottle of refrigerant yourself or take it to an ac auto repair shop.1 – Newer cars use a new refrigerant called R-134a. It has replaced R-12 which was called “Freon.” The R-134a is now used as it protects the environment by not using CFCs that can damage the ozone layer.2 – Your cars AC unit creates cold air by using the liquid refrigerant and then turning it into a gas. This gas then makes the ac in your car cold.If your car ac system is not working properly and you have used all the methods and tips above, you may need to take your car to an auto ac repair shop.
