How Much Can I Expect To Save On Energy If I Have A Solar System? A Question From Fircrest

September 12th, 2011

Everyone in Fircrest knows about the benefits of solar energy for the environment. It reduces carbon emissions, preserves nonrenewable natural resources, reduces dependence on oil, etc. That is all well and good, but in tight economic times the question always comes down to one thing: how much will you save. People want to know how much going solar can really save them on costs, and if you are reading this, then you are probably wondering the same thing, and with good reason.

Savings Are Variable

Somewhat disappointingly, that’s the answer. There a number of factors to consider in the cost of using solar energy and the subsequent savings, and after considering all of them you may decide solar isn’t right for you. There is no one right answer, but below you can see some guidelines which ought to give you a better idea:

  • Energy costs for an average American household are estimated at about $195 per month, and rising at a rate of about 3.75% each year.
  • The cost of installing a solar panel system is between $8 and $12 per watt (or $8,000 to $12,000 per kilowatt).
  • If your family uses 7 kilowatts of electricity per month, a solar panel system to offset 100% of your energy use will cost about $63,000. You can opt to get a less robust system to offset, say, 50% of current usage, however, for a lower cost. This is not set in stone either. Costs fluctuate depending on where you live and current component prices.
  • Despite the high initial cost, many solar systems are under warranty for 25 years, meaning you can expect them to last at least that long.
  • Depending on the utility price structure in your area, using solar for 50% of your household energy consumption may reduce costs by as much as 60%. Over 25 years, assuming the steady rate increase of 3.75%, your savings can be upwards of $60,000.

Keep in mind that these are only rough estimates. Research utility costs in your area and get estimates before installing. Solar energy calculator utilities are available online. You may find that there is a definite savings with solar, or that you can use a smaller system to offset a portion of your energy use. Or, you may even find that solar energy is not the right option for you. The important thing is to do your homework and choose the home energy solution that is best for you and your family.

When Should You Check Your AC Filters: Some Pointers From Eatonville

September 9th, 2011

The filters on your air conditioning unit are vital for keeping out the dust and debris that make things like illness, allergies and air quality worse in your Eatonville home. And it’s important that you take personal responsibility for checking those filters. Sure, you have a professional visit your home once a year to check the air conditioning, but you should also check the system yourself on a semi-regular basis for possible filter degradation.

Monthly Checks

So, how often should you check? Think of it this way. There is no such thing as checking too much, but you can easily not check often enough. So, we recommend checking your filter at least once every 4 weeks. It may not always need to be changed during that four week checkup (sometimes it can last 6 weeks or longer), but it’s good to take a peek.

Why is this so important? Because filters that haven’t been checked and changed as needed have a habit of building up excess sediment and debris. Not a problem when it comes to actually working, but a huge problem when it comes to your energy bill. The harder a system has to work to keep you house cool, the more energy it draws and the more you pay to have cool air in your home. And it will break down much faster as a result of overwork and dirty filters.

Changing an AC Filter

If your filter is ready for a swap, here are some quick tips to get the job done:

  • Find Your Filters – If you don’t know where your filters are, ask your contractor on the next visit or look near the return grills by the thermostat.
  • Remove the Filters – Open the latches and pull the old filter out to check it. You should be able to see clearly through a permanent filter and a disposable one should still be white. If this isn’t the case, it’s time for a cleaning/replacement.
  • Clean the Area – Clear the grill and area of any debris and sediment that might make the filter worse after replacement.

Proper filter maintenance only takes five minutes and it will save you money every month you run your AC – not a bad deal for a few minutes’ work.

How to Reduce the Load on Your Central Air Conditioner: A Guide From Renton

September 7th, 2011

Your central air conditioner can handle a lot. It can keep your Renton house cool and comfortable all summer long with only a minimum of maintenance. And if you have a newer, more energy efficient model, you probably are not even paying very much for this luxury. But no matter how good your air conditioning system is, it is always best if you can reduce its cooling load as much as possible.

Cutting down on the amount of work your central air conditioner has to do will save you money both in the short term and in the long term. You will be able to keep your house cool all summer while paying even less than you already do and you will help to extend the life of your system as well.

In general, reducing the cooling load that your air conditioner is responsible for involves keeping your house cooler by some other means. One great option when this is your goal is to have some ceiling fans installed. These help to circulate cool air and also create a breeze that can make it feel cooler even if the actual indoor temperature is the same.

With adequate ceiling fans in place, you will usually be able to turn up the thermostat on your central air conditioner and still be completely comfortable indoors. Turning up the temperature on the thermostat means that your air conditioning system will not have to work so hard because it will not have to get the indoor temperature down so low.

You can also reduce the indoor temperature in your house by blocking the sunlight that comes in and warms up the indoor air. Drawing the blinds, especially in those rooms that receive warmer afternoon sunlight will keep that sun from raising your indoor temperature. This, in turn, means that your air conditioning system will not have to work so hard to get the temperature back down.

You can also help to keep cool air inside and warmer air out by covering any doors and windows you are not likely to use with plastic. Also, check to make sure there are no cracks or drafts anywhere that may be letting in air from the outside or allowing cooler indoor air to escape. All of these things can make it possible for your air conditioner to keep your home cool without working so hard, and that will also mean that you will be paying less each month on your energy bills.

Why Select a Two Stage AC vs. Single Stage Air Conditioner: A Tip From Seatac

September 5th, 2011

When you are in the market for a new air conditioner in Seatac, one of the decisions you will have to make is whether you want a two stage system or one that only functions in a single stage. Of course, before you can make a decision about this, you need to know what all of this means.

A single stage air conditioning system is probably what you are most familiar with. They have been around for longer and can be found in a wide variety of locations. Single stage air conditioners come on at full capacity when the temperature in your home rises above the preset level on the thermostat. Once they have effectively cooled the house, these types of air conditioners shut off until the temperature works its way back up again.

Two stage air conditioners, on the other hand, can function at either 67% or 100% of capacity depending on exactly how warm it is in your home. What that really means is that if the temperature in your home is only a little above the thermostat’s preset limit, the air conditioning system will come on at 67% and gradually cool the house to keep it right in a comfortable range.

However, if you have not been home for a while and your home has gotten very warm inside, your air conditioner will come on at full power to get the temperature down quickly. What this really means is that your air conditioner will be running more than a single stage air conditioner because it will sometimes not be using all of its power to cool.

The end result of using a two stage air conditioner is that you will receive a relatively continuous flow of cool air throughout your home. A two stage air conditioner will send in a steady but smaller stream of cooled air as opposed to the large blast of cold air you would get from a single stage system.

This results in a more consistent and comfortable environment overall, and it also makes it possible for the air conditioning system to dehumidify your house more effectively. When the air is cooled too quickly, the dehumidification system does not always have time to do its job. But with the longer cooling cycles of the two stage system, there is plenty of time to make sure the right amount of humidity is removed from the air.

If you have more questions about which type of air conditioner is right for you, consult a professional.

Who Invented Air Conditioning? Some History From Tumwater

September 2nd, 2011

For hundreds of years, people have been trying to figure out how to stay cool in the heat of the summer, even in Tumwater. But it wasn’t until 1902 that the first modern air conditioner was put into service in Brooklyn, NY. Since then, many adjustments and improvements have been made to make air conditioning available and convenient for people to use in their homes and cars. But through it all, the basic principles used in that first air conditioner have remained constant.

The Sackett-Wilhelms Lithographing and Publishing Company

The heat and humidity in New York in the summer isn’t something to be taken lightly, but it posed particular problems for the owner of the Sackett-Wilhelms Lithographing and Publishing Company. The conditions inside his facility were such that the paper used was warping and the dimensions fluctuating, causing the printing to constantly come out misaligned.

To try and solve this problem, he hired the Buffalo Forge Company, which itself had just hired Willis Haviland Carrier, a recent recipient of a Master’s Degree in Engineering from Cornell University. Carrier approached this problem by trying to find a way to cool air by passing it over cold coils in the same way air was heated in those days by passing it over hot coils.

As it turned out, this process worked to reduce both the temperature and the humidity in the area and Carrier’s first air conditioner began running at Sackett-Wilhelms in July of 1902.

The Next Steps

As the potential for this new technology became more and more apparent, demand for Carrier’s device grew in all sectors of the economy. Employers were delighted by the way air conditioners increased the productivity of their workers during the hottest months of the year, and in order to keep up with demand, Carrier eventually founded the Carrier Air Conditioning Company which still exists today.

The coolants used in the earliest air conditioners were generally either highly flammable or toxic, and often both. In order to make air conditioning safer and easier to use, a safer coolant needed to be introduced, which was what drove Thomas Midgley, Jr. to develop Freon in 1928. Freon was initially made up of chlorofluorocarbons (CFCs), but as the disastrous environmental impacts of those chemicals became apparent, usage shifted first to hydrogenated chlorofluorocarbons (HCFCs) and then to the hydrofluorocarbons (HFCs) that are predominantly used today.

If you have any questions about modern air conditioning, contact an air conditioning contractor.

Why Install a Ductless Air Conditioner? A Question From Tukwila

August 31st, 2011

As you explore your options in terms of a new home air conditioning system in Tukwila, you will probably have to decide whether you want a system that uses ducts to get the cooled air around the house or one that is considered ductless. Each type of air conditioning system is appropriate in certain situations, so it is important to understand the benefits of each before you can make a decision.

Duct air conditioning systems are the more traditional type on the market today. They generally consist of an outdoor compressor and condenser unit and an indoor air handler. The outdoor unit passes the cooled air through ducts to the air handler, which then takes over circulating the air through the house and back out to the condenser again.

It makes sense to install this type of air conditioning system if you have a large house or if you have ducts already in place. Duct air conditioners can cool a moderate to large sized house quite effectively and they can also be coupled with zone control systems to give you multiple climate zones within your house.

Ductless air conditioners, as their name suggests, do not rely on a system of air ducts to get cooled air distributed throughout your house. These types of systems use refrigerant lines to transfer coolant from the outdoor compressor to the indoor, wall mounted units. Each of these indoor units can take care of cooling one or two rooms, but in order to cool an entire house with one of these systems, you will need to install multiple indoor units.

However, these multiple indoor units can all be connected to the same outdoor compressor, and they can also be controlled independently. That gives you much greater control over which parts of your house are cooled and how much energy you are using to cool areas that may or may not be occupied.

Ductless air conditioners are generally more energy efficient than ducted ones, but their real advantage comes from the facts that they can be installed even in places where air ducts do not exist or cannot go. If you do not already have ductwork in your house, installing a duct system will add considerably to the price of installing a ducted air conditioning system. In a case like this, a ductless system is much easier and cheaper to install and certainly makes more sense.

The Advantages of an Air Conditioning System: A Guide From Seatac

August 29th, 2011

Just about everyone in Seatac knows that air conditioning systems keep your indoor environment cool and comfortable during the hot summer months. While this may be enough of a benefit for you, there are also some other benefits to having a central air conditioning system installed in your house as well.

For instance, if you have someone in your household who is more susceptible to extreme temperatures than most people, an air conditioning system can actually help improve their overall health. Babies certainly fall into this category, as they have more difficulty than older children or adults do controlling their body temperature.

Also, many elderly people or people suffering from certain medical conditions, particularly heart conditions, are especially sensitive to the heat. If they are unable to stay cool, it can be very dangerous and damaging to their health, and an air conditioning system helps to guarantee that they will be able to stay cool and comfortable even on the hottest days of the year.

Aside from direct health concerns, air conditioning systems can also help to alleviate the symptoms of colds and allergies. They do this by controlling the level of humidity inside your home. If the air in your house is too moist or too dry, it can exacerbate cold and allergy symptoms, as well as dry out skin and make the indoor environment generally uncomfortable.

Proper humidity control is also important because it helps to ensure that any air filtration or purification system you have in place is able to operate at peak efficiency. Many of these units have a hard time extracting particulate contaminants from the indoor air that circulates through them if that air is too humid or too dry. With a state of the art air conditioning system in place, however, you will not have to worry about whether or not the humidity level in your home is out of balance.

It is also worth noting that a central air conditioning system can be preferable to a window mounted unit because it provides for a more even distribution of cool air throughout the house. Also, when you have a central air conditioning system, the condenser which is the source of most of the noise and vibrations that air conditioners make will be located outside and out of earshot. With window mounted units, on the other hand, there is really no way to block out or diminish the noise.

If you have any questions about how air conditioning help you feel more comfortable, contact your local contractor.

How to Handle an Overloaded AC: A Tip From Auburn

August 26th, 2011

The last thing you need on a hot summer day in Auburn is for your air conditioner to suddenly cut out. Without the cooling power it provides, your house will get uncomfortable quickly. Fortunately, once you know why this happens, there are several things you can do about it.

Why Air Conditioners Cut Out

The most common reason for air conditioner failure is an overabundance of pressure in the unit. This happens because the coil gets too hot, causing the pressure to rise in the entire device. As the pressure rises past a certain point, an automatic safety shutoff system is engaged. If you can stop the coil from heating up to this point, you can keep your air conditioner running.

How to Keep Them Running

Of course, this is easier said than done. Since your condenser unit with the coil inside is located outside in the heat, it’s only natural for it to get hot during the day – especially an extra hot day when you’re using your air conditioner a lot. You also need to be careful not to put anything over or up against your outdoor condenser unit.

While this may block the sunlight, it will also keep heat in the system and prevent the air conditioner from removing exhaust naturally. So in order to keep your air conditioner as cool as possible, make sure there is nothing up against the vents or impeding air flow in any way. Once you’ve done this, try and find a way to provide shade for you air conditioner without placing objects near the device. Blocking out direct sunlight is the best way to keep your air conditioner cool as long as you can do it without interfering with the system’s natural air flow.

Getting it Back On

If your unit does cut out on you, don’t despair. The best thing to do is to wait about a half hour to give your unit a chance to cool off on its own. Then, spray the coil and other overheated areas with a fine mist of cool water. This should lower the temperature enough that the system can come back on without any further complications.

If the problem persists despite the work you’ve done to keep it cool, you may want to call in a professional to take a look and make sure nothing is broken or worn inside to cause the overloads. Most of the time a little maintenance will take care of the problem, but if not, you’ll want to get repairs done quickly to avoid a full breakdown.

Green House Gasses and Air Conditioners: Some Pointers From Issaquah

August 24th, 2011

There’s simply no way around it: the air conditioner you probably depend on all summer in Issaquah is emitting a constant stream of greenhouse gasses contributing to the warming of the Earth. While it’s true that the coolants used today, hydrofluorocarbons (HFCs), are much less damaging than the chlorofluorocarbons (CFCs) initially used in air conditioning, they are still harmful to the environment.

Environmentally Friendly Coolants

Recently, research has led to the development of more environmentally friendly coolants. One in particular, HFO-1234yf, is scheduled to be introduced for use in the air conditioning systems of all GM cars beginning with the 2013 models. This is a step in the right direction, but much more needs to be done to address this growing problem before it’s too late.

Electricity and Carbon Dioxide

The use of environmentally friendly coolants will only go so far towards curbing the environmental impact of air conditioning. That’s because air conditioners are universally powered by electricity, and electricity is almost universally produced by the burning of fossil fuels like coal. When coal is burned, it generates a great deal of carbon dioxide, a substantial pollutant on its own.

An Intensifying Cycle

Of course, the more carbon dioxide and other greenhouse gasses are introduced into the atmosphere, the hotter the planet will become. And as the average temperature rises, air conditioning will be used more and more to combat these effects. This is a cycle that could quickly spiral out of control if something is not done to disrupt it.

What You Can Do

There are several things you can do if you’re concerned about how your air conditioning usage impacts the environment. First of all, make the switch as quickly as possible to HFO-1234yf or a similarly environmentally-friendly coolant when it becomes available. And remember that the air conditioning in your car counts too.

You can also go a long way towards reducing your contribution to greenhouse gas emissions by keeping your overall energy consumption down. Try relying on other, natural methods of cooling your home as much as possible. And when you do turn on your air conditioner, make sure you use all of the energy being consumed as efficiently as possible.

That means keeping your unit in good shape to maintain its energy efficiency and making sure that your home is properly sealed and insulated so your air conditioner doesn’t have to work overtime maintaining a comfortable indoor temperature. If you have more questions about energy efficient air conditioners, contact your local contractor.

Air Conditioners and Humidity: A Tip From Steilacoom

August 22nd, 2011

Ever wonder why all of those air conditioners hanging out of people’s windows in Steilacoom are constantly dripping water on hot summer days? All they’re actually doing is disposing of the moisture they’ve removed from the indoor air. That’s right – air conditioners are dehumidifiers too.

When you think about it, it makes a lot of sense. After all, you know how much more uncomfortable 90° is when the humidity’s up around 90% than when it’s closer to 60%. Of course, some air conditioners are better at removing moisture from the air than others, so you should definitely consider how well an air conditioner dehumidifies when evaluating your air conditioning options.

Why Humidity Matters

High humidity, even at lower temperatures is uncomfortable. But there are more reasons than simple comfort to want an air conditioner that reduces indoor humidity levels. For instance, high levels of humidity promote the growth and spread of several allergens like dust mites and mold spores. High indoor humidity can also cause problems for the wood fixtures and furnishings in your home.

The Importance of Proper Sizing

Most air conditioners do a decent job of controlling humidity indoors. But depending on the severity of your problem and the typical levels of humidity in your area during the summer months, you may want to pay special attention to each unit’s capabilities when evaluating your options.

An air conditioner’s ability to maintain proper humidity levels indoors has a lot to do with how well it’s matched to the size of your room as well. An air conditioner that’s too small likely won’t get the humidity or the temperature down to a comfortable level. On the other hand, that doesn’t necessarily mean that bigger is better.

In fact, an air conditioner that’s too large for the space you’re using it to cool will have a hard time bringing down the humidity level. Sure, you’ll wind up with a cold room, but that room will remain damp, making it no more comfortable than it was before the air conditioner was turned on.

For all of these reasons, it’s important to carefully evaluate your options when buying an air conditioner and make sure that the unit you buy is the right kind and size for the area you’re cooling. A little extra time spent researching your options will make your home infinitely more comfortable this summer. If you have more questions about which air conditioner is right for you, contact your local AC contractor.
