HVAC Tip: How Electronic Air Filter Works

Monday, April 2nd, 2012

For a long time, the most frequently used kind of air filter has been the mechanical variety, and it probably what you already have in your Orange County HVAC system. This is the kind you probably think of when you hear the terms air filter, air cleaner or air purifier. They use pleated fibrous filters in-line with an air handler to trap particles in the air before circulating it back out into the home.

Many models of these work very well and have for many years. They have the added benefit of being flexible because you can put in whatever filter you need depending on what size particles you need to trap.

However, these traditional devices are not the only option. A second kind of air filter exists for trapping particles in the air– one that does not use a fibrous filter that physically snags them out of the air on the way through.

These electrostatic — or electronic — air cleaners work in a different way to produce a similar result. The filtering component is still a fibrous sheet, but the difference is that the fibers are made of plastic, which becomes charged when air passes through it and causes friction.

(Think something like when you rub a balloon and stick it to the wall.)

These friction-charged fibers carry an electronic charge, which attracts the ions in the air around it. These ions — and the particles that they are a part of — get trapped in the fibers and stay out of your air supply.

 Electronic air filters are generally very good at trapping particles that are 1 micron in size or higher, putting them about on par with a mechanical air filter that carries a MERV rating of 12. The electrostatic method works well for many common household air pollutants, such as dust, pollen, mold and pet dander.

As with many ventilation-related decisions, the choice of what kind of air filter is right for your Orange County air conditioning and heating system depends on your needs and those of your family. If you are having trouble deciding, then an air quality assessment and consultation with Saddleback Plumbing, Heating & Air Conditioning can be a good way to reach a decision.

How Do EER and SEER Work? A Question From La Habra

Wednesday, September 21st, 2011

If you’ve looked for a new air conditioner in La Habra recently, you probably noticed each unit comes with an EER or SEER rating. The former is for room air conditioners and the latter for central air conditioning units. In both cases, the number is a measure of how efficiently the system uses electricity. Effectively, if you buy a system with a high rating, you spend less on electricity. Of course, there are tradeoffs. The higher rated machines tend to cost much more, so as a homeowner, you’ll have to evaluate how much you can spend now and how long it will take to save money from that investment.

How EER and SEER Are Measured

These numbers are required by the government to tell you, the consumer, how many BTUs per hour the device can use for every watt of electricity drawn. The more BTUs a system can use, the better for your bill.

Let’s say you want to buy a 10,000 BTU system to cool your living room and dining room. A pretty standard number for a single room unit is 11, meaning the 10,000 BTU system would use about 900 watts per hour to run at full capacity. We figure this out by dividing the BTUs (10,000) by the watts (900).

There is a lot of math to do here, so many people simply look for a higher number within their price range. But, at what point is the upgrade really worth your extra money?

Choosing the Right Energy Efficiency Rating

The easiest way to describe this is to compare two similar devices with different EERs:

Air Conditioner 1 Air Conditioner 2
BTUs 12,000 12,000
EER 9 11
Watts 1333 1091
Price $300 $450

In this particular case, we can spend more for a device that is the same size but uses less electricity. The question then is whether that increased expenditure will pay off in the short term. Let’s assume each device would be operated for 10 hours per day for 30 days in a typical summer month. That’s 300 hours of operation. If the average cost per kWh in you are is $0.09, it will take 4 hours for the first air conditioner to consume 1 extra kilowatt of electricity equal to an additional $0.09. If your air conditioner runs for four months out of the year, we know that it will operate for a total of 1200 hours. That means:

[(1200 hrs x 242 watts) / (1000 watts/kw) ] x $0.09/kWh = $26

So, you save roughly $26 per year from that high efficiency unit. With a $150 price difference, you will break even after 6 years (though probably sooner if the price of electricity goes up).

Don’t forget, however, that central systems are a much more efficient option with SEERs of up to 16.5 and much larger BTU areas to cover. The savings there can add up very quickly. If you have any questions, contact your local air conditioning professional.

AC As a Safety Feature in the Home: Some Advice From Woodbridge

Monday, September 19th, 2011

Ask a hundred people in Woodbridge what the primary role of air conditioning is and I’ll bet you they say “comfort”. We seek out AC to stay cool and beat the summer heat, but did you know your air conditioning is a lot more than just a convenience – it is a safety feature in the midst of heavy heat waves.

Heat Is More than Just Uncomfortable

We tend to think of heat as this massive, uncomfortable inconvenience. In reality, it is quite dangerous. According to the Center for Disease Control, heat waves killed 8,015 people between 1979-2003, more than hurricanes, tornadoes, lightning, earthquakes and floods combined in that time period.

Why is heat illness so dangerous? It comes on quickly and it’s easy to ignore the warning signs, especially when you are already uncomfortable. While hydration is important, the real risk occurs after you’ve become dehydrated – when your body can no longer keep itself cool. This is known as heat stroke and can lead to a number of life threatening conditions, especially for the elderly, infants and those with chronic conditions.

That’s where air conditioning comes in. On the CDC’s extreme heat preparedness webpage, air conditioning is listed as the number one preventative factor against heat related illness. Simply put – if you have an air conditioner, there is a much smaller chance you will get sick from the heat. Dehydration happens less frequently when you’re in an air conditioned environment, meaning that your body can regulate temperature internally and you feel comfortable – not a bad deal for a simple installation.

Staying Cool Is a Medical Necessity

Heat is more than just a direct threat. It addles the mind and makes your reaction times slower. In effect, by allowing your body to overheat, you put yourself at risk. Simple tasks like climbing a ladder or taking out the trash could result in an injury because you don’t have the energy or the mental clarity to perform them as you would on a normal day.

So, air conditioning is about a lot more than just staying comfortable – it’s a health issue. Especially if you have small children or elderly adults in the house or if anyone in your family has a medical condition like obesity, heart disease, mental illness, poor circulation, an air conditioning system is an absolute must during heat waves.

Choosing an Environmentally Friendly Refrigerant for Your Air Conditioner

Friday, September 9th, 2011

For years in La Habra, we heard about how bad air conditioners were for the environment. Specifically, the liquid used in them to remove heat from air in your home tended to eat holes in the Ozone layer. Today however, air conditioners (along with every other appliance or device that uses refrigerant) have been upgraded to work with newer, better chemicals.

R-22 Refrigerant

While R-22 refrigerant is still used in devices sold today, it is being gradually phased out. According to the Montreal Protocol, R-22 refrigerant will no longer be allowed in new devices as of January 1, 2020 in the United States (though it can be used to service existing devices via recycled or reused refrigerant). While the most environmentally damaging refrigerants such as HCFC-141b have been removed from the market, R-22 is still considered harmful to the environment if allowed to enter the atmosphere.

R-410A Refrigerant

So, if R-22 will soon not be permitted (and is not an environmentally friendly option), what is? Currently, the most common refrigerant used in new residential air conditioners is R-410A. After the Clean Air Act was passed, the EPA reviewed a number of refrigerants to determine which were the least damaging to the environment (and human health) and which could be used as alternatives to R-22. At the top of the list is R-410A, a blend of different HFCs that don’t deplete the ozone. Sometimes called Puron, Forane, or Genetron AZ-20, R-410A is a good choice if you’re having a new system installed.

Other Alternatives

Of course, because R-410A is a hydrofluorocarbon, it does contribute to global warming and therefore is a risk to the environment, albeit in a much smaller capacity than older refrigerants. Recently, the EPA approved the use of HFO-1234yf – a chemical that pollutes 99.7% less than the current refrigerant used in car air conditioners. Whether it will be used in homes and commercial spaces remains to be seen, but the technology is advancing rapidly, allowing us to stay cool without sacrificing our planet’s health and future to do so.

Another alternative is to invest in an evaporative cooling system rather than a traditional air conditioner. These systems use no HFCs at all and therefore have zero impact on the ozone layer or global warming (other than the electricity they consume). They also use 80% less energy than traditional air conditioners. If you live in a dry, low humidity climate they are a great option.

Warning Signs: When to Call for an Air Conditioning Service in Fountain Valley

Wednesday, August 17th, 2011

The last thing you want is to be without an air conditioner during the hottest days of the year, especially in Fountain Valley. Ideally you would never have to call for service to repair your air conditioning system, but just like anything else, your air conditioner will break down once in a while. However, you can dramatically reduce the inconvenience and cost of emergency air conditioning repairs if you are able to spot the warning signs of a problem before it shuts down your system completely.

For instance, all air conditioners make noise, but if your air conditioning system is suddenly making much more noise than it used to, chances are that something in there is not working properly. Calling for repairs when you notice this sudden increase in noise from your system will greatly increase the chances that the repair will be relatively minor and that you will not have to go without air conditioning when you need it most.

Also, it is a good idea to call for service if your air conditioning system does not seem to be doing as good a job as it used to when it comes to cooling your home evenly and effectively. Uneven cooling is a good sign that something is not working right within your system. And even if your air conditioner continues to work, it will probably be using up more energy than necessary for a less than ideal end result.

Along these same lines, a noticeable increase in humidity in all or part of your home is another good indication that something is wrong with your air conditioning system. Air conditioners both cool and dehumidify the air, so if yours stops removing humidity properly, you need to find out why.

In fact, even if you do not notice any difference in the way that your air conditioner is performing, you can still spot a problem if you keep a close eye on your energy bill. If you see a sudden increase in the amount of your bill because of the amount of energy that your air conditioning system is using, it is a good sign that something is not working right.

It may be tempting to put off calling for repairs, particularly if your air conditioner is still able to keep your house comfortable. However, it will likely be much cheaper and more convenient to have the repairs done early rather than waiting until the unit breaks down entirely.

Pipe Inspection Camera: When to Use One

Friday, June 10th, 2011

For plumbers today, pipe inspection cameras are a huge aide. In the past, it was often very difficult to determine the location of a blockage or a leak, or indeed if one even existed at all. But now with this great modern equipment, it is much easier to get a thorough picture of the exact state of a pipe system and the nature of a potential problem.

These types of inspection cameras are especially useful when a clog is located underground or when an underground leak is suspected. Many types of plumbing problems can have multiple possible causes. But with pipeline inspection cameras, you can know for sure quickly exactly what type of problem you are dealing with.

For instance, even if you know that an underground pipe is leaking, it can be next to impossible to figure out exactly where the leak is. But to fix the leak you will have to unearth the damaged section of pipe and repair it. If you cannot pinpoint the leak precisely, you will be forced to unearth a large section of pipe. This takes a long time and causes unnecessary, although hopefully temporary damage to your yard as well.

However, if you can determine exactly where the leak is, you can dig up only the affected portion of pipe. This saves a lot of time and labor and it also means that you can limit the disruption the work causes in your yard. And the best way to find a leak like this is to use a pipe inspection camera to get a look at the inside of the pipe before you ever begin digging.

You do not need to wait for an emergency situation to develop to make use of a pipe inspection camera either. This technology is also extremely useful during annual drainage and sewer maintenance visits to help ensure that there are no unnoticed problems lurking below the surface. It is perfectly possible that one of your pipes is getting close to cracking but has not done so yet. The repairs can be a lot simpler if you catch this type of problem early, and that is exactly what a pipe inspection camera makes possible.

Pipe inspection cameras are also useful during maintenance visits because they allow technicians to determine which parts of your system need the most work. They can see where the larger buildups are and get the job done quicker overall than they could if they were operating blind.

Changes in Light Bulb Laws and Technology

Friday, June 3rd, 2011

In 2007, Congress passed the Energy Independence and Security Act, which promoted many forms of renewable energy and energy conservation. Its provisions include changes to the minimum standards for light bulb efficiency. Although the new standards haven’t officially gone into effect yet, you many already have seen changes in the kinds of light bulbs on sale in your local hardware store.

According to the law, starting in 2012, most standard general-purpose bulbs must be 30% more energy efficient than current incandescent bulbs. The new requirements will be phased in gradually, but the net result will be that by 2014, most of today’s incandescent bulbs will no longer be available for sale, and will be replaced by compact florescent light bulbs, or CFLs.

Of course, higher-efficiency bulbs are good for the environment. Moving to more efficient lighting is one of the easiest, lowest-cost ways for the U.S. to reduce electricity use and carbon emissions. But the changes will also benefit consumers – some estimates suggest that the average household’s utility bill will be reduced by as much as 12%. Even though CFLs cost more to buy ($3 compared to 50 cents for an incandescent), they use about 75% less energy and last five years instead of a few months. Depending on the cost of electricity, a homeowner that invests $90 to change 30 bulbs to CFLs will save between $440 and $1500 over the five-year life of the bulbs.

CFLs do have their detractors. Many claim that they don’t last anywhere near as long as the five years claimed by manufacturers – and this can in fact be the case you turn the bulbs on and off frequently. Energy Star recommends that all CFLs be left on for at least 15 minutes at a time. (Also, if you are using the bulbs in a dimmer, make sure that you buy bulbs specifically marked “dimmable”.) If you buy Energy Star bulbs, they come with a two-year warranty, so save your receipts and contact the bulb’s manufacturer if it burns out prematurely.

Others dislike the white – sometimes called “harsh” – light of CFLs. This effect can be mitigated by buying cooler-burning CFLs. Bulbs with Kelvin temperatures in the range of 2,700 to 3,000 emit a warmer light than higher-temperature bulbs with Kelvin temperatures of 5,000 or higher, which tend to have a white or bluish light.

Still other critics point out that CFLs contain mercury. While this is true, incandescent bulbs are not mercury-free in practice either. The increased power used for incandescent likely comes from coal-powered plants that produce mercury and many other types of pollution.

If you do break a CFL in your home, consult the EPA’s website for instructions on how to clean it up safely.

Of course, manufacturers are preparing for 2012 by developing new kinds of light bulbs that meet the more stringent standards, including high-efficiency incandescent and LED bulbs, so look for these options to arrive in stores over the next year or so.

The good news? A much less-beloved light bulb has already been phased out. The T-12 fluorescent tube – those humming, flickering office lights that give everyone’s skin a miserable greenish cast – has been replaced by T-8 fluorescent tubes, which are quieter, more efficient, don’t flicker, and make colors look much more natural.

Save with Maintenance on HVAC

Wednesday, March 2nd, 2011

You can never save too much money by making improvements and taking steps around the house. Of course, it is hard sometimes to see exactly where the money saving opportunities are. That’s because you expect to spend a certain amount on various types of services when you own a home. You know you are always going to have heating and cooling bills, for instance. But are they higher than they need to be?

For many people, the answer to that question is “yes.” And it is not because they use their home heating and cooling systems inappropriately or because they have the wrong equipment. It is simply because they neglect to get their HVAC systems the regular care and maintenance that would keep them running at peak effectiveness and energy efficiency.

When your HVAC system is new, it runs well and can be remarkably energy efficient. However, over time that energy efficiency will gradually deteriorate. This drop off in efficiency is often not obvious at first, but if you compare your energy bills from the year you got your system to bills for the same time of year and same usage five years later, you will probably notice that the bill has gone up quite a bit, and not just because energy prices have gone up.

You can do a lot to prevent this loss of energy efficiency, though, if you simply have a professional HVAC technician come out once a year and give your system a tune up. During this type of maintenance service, the technician will check over your entire system looking for worn out parts and buildup that could be interfering with your system’s performance.

They can clean out any areas of your HVAC equipment that require it and they will be able to make any necessary repairs at that time. Often, a technician performing this type of maintenance will be able to catch minor issues before they are able to develop into bigger problems. And while you still have to pay for the maintenance visit, the cost is much less than what you would pay for an emergency repair.

It also represents a substantial savings over what you would be paying on your energy bills every month without it. Regular HVAC maintenance can preserve the vast majority of your system’s energy efficiency loss over time, and it is never too late to start. Even if it has been several years since you had your system installed, you will still be able to get back the vast majority of your original energy efficiency by starting with regular maintenance now.
