Incidents of counterfeit R-22 are on the rise—with dangerous and costly results. Canoga Park Heating & Air Conditioning cares about our clients, and we want to ensure they have the best information available. Consider the following before buying or recharging an AC unit.
Learning About R-22
R-22 is the refrigerant inside many air conditioning units; the refrigerant is composed of liquids and gases with cooling properties. The refrigerant has a negative impact on the ozone layer when emitted from cooling units. As a result, the government mandated that production must slow down and come to a halt by 2020. Recycled R-22 will remain legal after the cutoff. However, timeframe of the completed phase-out will depend on contractors turning in the refrigerant for recycling, making it difficult to determine how much will be available.
Decreased availability of R-22 caused its price to soar. In 1998, a pound of R-22 cost about $10, but by 2013, the same amount cost approximately $50—and prices have continued to climb. Lower availability and higher costs led to a growing counterfeit industry, which presents serious risks.
Understanding The Dangers Of Counterfeit R-22
Counterfeit R-22 usually contains combinations of hydrocarbons that make it flammable. Fake versions of the approved alternative R410 (M099 and R438A) are flooding the market. Exporters, most often China-based producers, are importing both of these substances illegally.
It’s important for all American distributors and contractors to buy only from trusted sources and to quality-check these products. We encourage all homeowners to use reputable sellers to avoid potential hazards.
In the short term, counterfeit refrigerants are costly to use because they’re frequently less effective than their legitimate counterparts. Our experience is that users must run cooling units more often to maintain a reasonable temperature, increasing energy bills. In the long term, counterfeit R-22 can cause severe damage; the flammable substances may ignite, leading to fire or explosion, which can cause injury or loss of life.
Producers typically incorrectly label much of the counterfeit R-22 as nonflammable, and some counterfeits even bear knock-off name-brand labels. However, propane and isobutene are often primary ingredients in these substances, making them incredibly dangerous.

As summer heats up in California, many people seek air conditioning solutions for their homes. Portable air conditioner units may seem appealing at first, but several factors make them less attractive than window units. At Canoga Park Heating & Air Conditioning, were committed to connecting clients with the best possible units for their spaces. Before investing in a portable AC, review the FAQs below and feel free to reach out with any questions.
How Portable Are These AC Units?
We’ve found that portable AC units aren’t as mobile as advertised. Frequently displayed without hoses and marketed as no-installation systems, these units seem like quick, easy cooling solutions. However, all AC units work by dispersing warm air outside the building, which presents some difficulties when it comes to portable devices.
Window AC units employ coolants to move heat from inside the home into coils outside the house, where it’s expelled. A portable device works similarly, except the coils are indoors. A hose resembling a clothing dryer vent hose must connect to the coils. Warm air travels through these tubes and is released outside. In combination with its 50- to 80-pound weight, this large hose attachment makes portable AC units less mobile.
Because the tube must connect the coil to the outdoors to expel hot air, you must install venting kits in a window or wall for every room in which you use the AC unit negating the claim that a portable air conditioner needs no installation.
Is A Portable Air Conditioner Unit Energy Efficient?
We measure the amount of hot air an AC unit can remove from a given space within an hour in British thermal units (BTUs). A larger room or warmer climate requires a higher BTU air conditioner to be effective. Portable and window AC units are both measured with this system, but these ratings can be misleading.
A portable unit measuring the same BTUs as a window unit doesn’t cool at the same rate. Since air moves through coils and a hose that are both indoors, some redistribution of heat into the home is inevitable with portable units. In general, portable AC units are dramatically less energy efficient because they must run for extended periods to attain the same cooling impact as window units.
Will A Portable Unit Create A Vacuum?
Window ACs can circulate air from the outside to the inside, producing fresh air. People tend to seal off areas that have an AC running to make the most of the cooling capacity, which is safe with a window unit. However, portable units create a closed system, since they only expel and don’t bring fresh air into the home. An unfortunate side effect this recycled air, is that occupants re-breathe the same air, which isn’t healthy. The vacuum that portable AC units create in a home is a serious concern.
Are The Risks Worth The Benefits?
Consider the above complications before investing in a portable air conditioner unit. Are the risks worth the benefits you have from owning a portable AC unit?

We’re here to help residents of the greater Los Angeles area with all their HVAC needs, and we’ll happily answer any of your questions.
In 1902, Willis Carrier invented the first modern electrical air conditioner. However, previous generations had their own ways of fighting the heat and keeping themselves cool during the summer. Throughout human history, people have come up with ingenious ways to stay cool during the hottest times of the year.
Geothermal and Water Cooling: Everything Old Is New Again
In almost every way, human technology has advanced by light-years since the Stone Age. However, state-of-the-art geothermal cooling relies on the same principle that our cave-dwelling ancestors understood millennia ago: it’s cooler underground. The earliest humans dug burrows or settled in existing caves in order to escape the heat above ground.
Water cooling is another piece of technology that we associate with modern air conditioning, but this idea is as old as the Pyramids—literally. The ancient Egyptians used to hang wet reeds in their windows so that the water would cool the breezes sweeping in from the hot Nile River valley.
The Invention of the Fan
Moving air has a greater cooling effect on the skin than stationary air, which is why breezes feel so delightful on hot days. Centuries ago, people realized they could make their own breezes with the use of hand-held fans. The invention of the fan cannot be traced to a single person or place, but archeologists have found evidence of hand-held fans as far back as the 2nd century BCE in China and the 4th century BCE in Greece.
Almost all modern air conditioners still rely on fans, albeit mechanical ones. Fans in modern air conditioners help to cool the air, and are also used to moved cool or warm air from one place to another through systems of ducts.
Going With the (Air) Flow: Victorian Ingenuity
The Victorian corset may have made breathing difficult, but in other ways the Victorians were masters of air flow. High ceilings, large recessed windows and covered porches all helped to maximize cross-ventilation in Victorian homes in order to improve natural cooling. High ceilings allow warm air to move upward, away from the people trying to stay cool. Covered porches and recessed windows use shade to cool outside air before breezes move this cooler air inside.
The Accidental Invention: Willis Carrier Modernizes Air Conditioning
Human ingenuity has repeatedly tackled head-on the problem of staying cool, and yet the modernization of air conditioning happened almost by accident. Willis Carrier, inventor of the first electrical air conditioner, was actually trying to find a way to control humidity in a printing plant. He decided to reverse the process of steam heating by passing air through cold coils , thereby causing the air to cool and the water in it to condense. It was a great way to control humidity, and an even better way to air condition a building.

When your air conditioner is running but your home is gradually getting warmer, you have a problem. Hold your hand over the supply registers. Do you feel little to no airflow coming from them? Your air conditioner is frozen. Whether you see any ice or not, your air conditioning unit is clearly letting you know there is ice in it. There are steps you immediately need to take to prevent damage to your unit’s compressor and further waste of money.
Handling Air Conditioner Freezes
Turn your A/C unit off immediately to prevent any (or further) damage to your compressor. While waiting for the accumulated ice to melt, find the drain for the condensation pan and be sure it is not blocked. If it is, unblock it. If you can, turn on the air conditioner’s fan without running the compressor. This will accelerate the melting of the ice. Once all the ice is melted and unblocked drains are clear, turn your unit back on. It should begin to cool your home again right away.
What Causes My A/C to Freeze?
Several maintenance-related issues are usually the culprits of air conditioner freezes. One of the main ones is low airflow due to a dirty air filter. When the filter is dirty, less air flow is delivered to the evaporator coil for cooling and distributing throughout the house. Having a sufficient flow of humid, hot air is important to prevent stress on your A/C compressor and to flow over the coil to keep it from freezing. Clean your filter monthly. If you close supply registers in unused rooms to save money, be sure not to close more than one quarter of your home’s total registers to prevent a freeze. Closing too many will overload the system.
The unit’s fan has to blow fast enough to send the right volume of air streaming over your evaporator coil. If slow fan speed caused your unit to freeze, a HVAC technician can increase the speed of your fan to eliminate this problem. If your air conditioner runs all night, it will eventually lead to a frozen unit. Your thermostat can be adjusted to prevent this. If an adjustment does not correct this, then your thermostat needs maintenance or replacement. When your refrigerant level is too low, either from improper charging or leakage, these low levels will make the evaporator coil too cold and lead to a freeze. Call an HVAC professional to check the unit and repair/recharge your coolant level.
As mentioned earlier, make sure your window unit is tilted correctly. The indoor portion of the unit should be slightly higher than the outdoor portion for proper drainage and the drain hole should remain open. The central air conditioner coil removes water vapor from that humid, hot air that blows across it. This water drips into a drainage pan then out through a floor drain unless the drain becomes blocked. When blocked, it freezes all the way back to the coil, blocks the drain and increased the trouble. Check and clear your drain each week during the hottest weeks of the year.
Regular Maintenance is the Best Prevention
The best way to prevent a frozen air conditioner is also the proper way to maintain the life of your unit. Change your filter each month and have a thorough performance evaluation check of your system’s components yearly.

Air conditioners, like other machines, wear down with time. As a result, they become inefficient. They start consuming more power, performing poorly and making strange noises. When this happens, property owners might start to consider AC replacement options. Unfortunately, it is somewhat challenging for the average person to decide whether to replace or repair. The following tips will help you know when it’s time to replace your AC system.
Life Expectancy of AC Machines
A good indication that it’s time to replace your air conditioner is the lifespan of the machine. The average AC unit has a lifespan of 8 to 12 years. As the device nears the end of its life, it becomes too inefficient to operate. The repair costs arising from frequent breakdowns also become unreasonable. Once a machine reaches the end of its useful life, it should be replaced. Property owners should therefore start making the necessary arrangements well in advance.
Current Condition of the Air Conditioner
While a machine may have reached the end of its useful life, it may still be functioning properly with high efficiency. In such a case, there is no need to replace the device immediately. However, there are cases where the air conditioner may be breaking down frequently and performing poorly even before it reaches the halfway mark of its expected lifespan. Air conditioning replacement may be a good idea in such cases.
Energy Efficiency Ratios
It is a well known fact that newer air conditioning machines are much more efficient than older devices. This is largely due to improved cooling technology. The seasonal energy efficiency ratio and the energy efficiency ratio (SEER and EER respectively) of the AC should be compared to the efficiency of newer machines. If increased efficiency leads to huge energy savings, then replacing the machine makes sense.

Like most of us, you have probably been influenced by stories of how to improve your home cooling. Some of these suggestions may be among the many falsehoods that are generously shared between homeowners. Here, are at least five common cooling myths that can be discredited:
Myth No. 1: Fans Cool Down a Room
Fans have one purpose, to move air around. When this air blows across your body, it feels cool, so you naturally assume the air is cooled down. In fact, the air is as uncomfortably warm after it’s blown across your body as before it began to move. The only time fans cool a room is when they draw cooler air from outside to the inside.
Myth No. 2: Air Conditioners Only Cool Air
It is a known fact that humid air feels hotter than dry air. Another function of your air conditioner is to remove humidity from a room using a drying function built into the unit. When this function isn’t working properly, your home will seem hotter. If your air conditioner lacks this function, try adding a dehumidifier to the rooms you want cooled.
Myth No. 3: A Larger Air Conditioner Will Cool Your Home Better
The reason your air conditioner is not cooling your home sufficiently may be due to it needing maintenance. It may be installed in an area that receives direct sunlight for too many hours, limiting its effectiveness. The last reason your air conditioner may not be cooling down your home is due to your home’s weather proofing. Too many air leaks and/or too little insulation can be reducing the effects of your air conditioner. Repair these problems and your old unit will probably cool your home once again.
Myth No. 4: Lowering the Temperature for Faster Cooling is good
Setting the thermostat at a lower temperature could be a problem if you forget to turn up the thermostat again. Your home could get too cold and you’ll be just as uncomfortable cold as you were when it was hot. If you have a window unit, lowering the thermostat is fine as long as you remember to raise the temperature at some point, so your family can be comfortable, not cold.
Myth No. 5: It’s More Efficient to Keep the Temperature Constant All Day
The fact of the matter is adjusting the temperature only allows you to get the comfortable setting you desire. Adjusting the temperature when you are sleeping, when you’re away from home and when you are at home only allow you to use the energy your family absolutely must use to keep your home comfortable. When you keep the temperature higher all day, you use too much energy, energy that is wasted.
Ignoring these of wives’ tales will save you money and possibly increase your comfort level. Erase these myths from your thoughts and try the alternatives.

Savings is important for every household. If you wish to save more on your future electricity bills, you can get a programmable thermostat to control your HVAC system. It’s not enough to have heaters and coolers with the Energy Star logo, especially if you are in a place where you need to use your HVAC system on a daily basis. If you haven’t heard about syncing your HVAC machine to a programmable thermostat before, make sure that you read the article below so you can start saving.
How does a programmable thermostat work?
This tiny device works by controlling the heating and air-conditioning units in your home. This means that when you set a specific temperature, the system will automatically adjust to meet it. Through the help of a programmable thermostat, you don’t need to manually change the settings on your HVAC system often. You also don’t need to carry the cooler and heater remote controls wherever you go just to meet your cooling and heating needs. Though this device is small, it can help you save energy because your system won’t have a hard time adjusting to the altering weather conditions.
Can a programmable thermostat help me save energy when I am away from home?
Yes, you can have energy savings, even when you are not at home if you have a programmable thermostat linked to your HVAC system. Most modern-day thermostats have energy-saving gauges that can be activated whenever needed. For instance, if you are going to work and you want to make sure that your place is as cool or warm when you get back, you can use the specialized dials on your thermostat so your machine won’t need to work double-time in case it gets too hot or too cold when you’re away.
What should I do if I can’t activate or link my programmable thermostat to my heating and cooling system?
