What Is AFUE and Why Should I Care? A Question from Hackensack

October 12th, 2011

If you’ve been shopping for a furnace in Hackensack, chances are you’ve noticed that each furnace has its own annual fuel utilization efficiency (AFUE) rating. These generally range from 80% to the high 90% s and the higher the number, the more fuel efficient that particular furnace is.

But what does this number really mean and just how much should you care? Well, the AFUE rating should actually have a significant impact on your furnace purchasing decision, but that doesn’t mean that you’ll always choose the furnace with the highest efficiency rating either.

For one thing, you’ll have to recognize that not every type of furnace is capable of running at the highest efficiency levels. Oil furnaces, for instance, can’t compete with the super high efficiency gas furnaces on the market today. That’s not to say that an oil furnace might not be the best choice for you under certain circumstances, but it does mean that you should take a close look at your furnace usage before you make a decision.

If you do choose a gas furnace, you will of course have the option of getting one that can reach up to 97% or so efficiency. However, that may not always be the best choice either. If you live in a place where with very harsh, long winters and you’re going to be using your furnace heavily, then it’s definitely worth investing in a higher AFUE furnace that can save you considerable amounts on your monthly heating bills.

But if you don’t use your furnace too often as your area has more mild winters it’s probably not worth it for you to invest in such a high efficiency product. That’s because the higher the AFUE of the furnace, the more expensive it is to purchase and install. Certainly you’ll save money every month because you’ll be getting more heat out of the fuel you’re paying for. But if you don’t use your furnace all that much, the savings really won’t be that substantial.

Don’t forget that a furnace with an 80% AFUE rating is still quite energy efficient. If you have any questions, talk to your HVAC contractor.

Maintenance Tips From Bergen County: Why You Should Have Your Furnace Serviced Every Heating Season

October 5th, 2011

Particularly if you’ve just purchased a new furnace in Bergen County, it’s probably not something you think about all that much. As long as it works when you need it to, that is. Unfortunately you usually find out that something is wrong with your furnace just when you need it most. However, there is a way to avoid that kind of problem, and many others, and that’s to have regular maintenance service performed on your furnace by a home heating professional every year.

One of the main reasons to have your furnace serviced is that it allows technicians to catch small problems before they become large ones. During a typical maintenance visit, a technician will examine all parts of your furnace to ensure that they are still in good working order. He’ll also thoroughly clean out the unit to make sure there are no buildups of debris that could cause problems or impede the furnace’s energy efficiency.

And if they do find something wrong like a part that’s beginning to wear out or something that just isn’t working properly, the technician can make the necessary repairs right away. You can get the problem taken care of ahead of time and you won’t have to worry about going without heat during the coldest part of the winter.

That’s not the only reason that annual maintenance is important and beneficial, however. It can also help you save money, both on your monthly energy bills and in the long term. That’s because annual maintenance tune ups keep your furnace functioning at peak efficiency levels longer than they would be able to otherwise.

A typical furnace will lose a small percentage of its energy efficiency every year, and while it won’t seem like a lot at first, that can really add up over the course of a couple of years. With regular maintenance, though, you can often maintain up to 95% of your furnace’s original efficiency for the life of the furnace.

Plus, when the proper maintenance and service is performed on a regular basis, your furnace will simply last longer.

Humidification/Dehumidification: A Guide From Waldwick

September 28th, 2011

Most people don’t think much about the humidity in their Waldwick home unless it gets unbearably high in the summer or extremely low in the winter. However, even slightly low or high humidity levels can have a huge impact on your indoor air quality, so even if you feel comfortable most of the time, a humidifier or dehumidifier is something you should look into. Many homes have humidity problems, and even if it’s not something you notice on a regular basis, air that’s too moist or too dry can have a large impact on your family’s health and the overall quality of your indoor air.

The Risks of High and Low Humidity

There are many reasons that proper humidity in your home is so important. For one thing, air that’s too humid promotes the growth of things like mold and dust mites that are significant airborne allergens. Without enough moisture, however, mold and dust mites can’t grow, so if you keep your indoor humidity below 50%, you’ll likely never need to worry about these allergens disrupting your family’s health or causing damage to your furniture.

But, dry air isn’t much better. Once the humidity level gets below 35%, a number of negative things can happen. Dry air enhances the symptoms of asthma, colds and allergies, and it causes damage to the wood fixtures and furnishings in your home. Even if it doesn’t do so much damage, dry air is simply uncomfortable, causing dried out skin, eyes, and hair.

Why Humidity Control Matters

Even if you have a state of the art air quality system installed in your home, humidity is very much something you need to be concerned about. Air that’s too moist or too dry can actually make it more difficult for indoor air cleaners and filters to get those contaminants out. In effect, poor humidity control makes every aspect of your air quality worse.

So if you want to be sure you’re getting the most possible out of your indoor air cleaner, the best thing you can do is put in a good humidification system as well. And when you’ve done that, you may even find that you can turn down the heat and air conditioning as well. Properly humidified air makes home heating and cooling more efficient, saving you both money on your monthly energy bill and wear and tear on your system. No matter how you look at it, proper humidity control is good for you and your home.

Green Thinking for Green Thinkers: A Guide From Lyndhurst

September 21st, 2011

There are a lot of media stories in Lyndhurst about exciting new green buildings: LEED-certified buildings, net-zero buildings, buildings made out of recycled shipping containers, homes in New Urbanist communities, even “ultra-small” homes. But a new home can be pricey. Fortunately, though, all these innovative green ideas can be applied where you live right now. In fact, going green in your existing home might even be better for the environment than building a brand-new home.

If you wish your home could be LEED-accredited, focus on energy conservation and indoor air quality in your existing home. Upgrade to a high-efficiency furnace and air conditioner and consider adding central air cleaners to your heating and cooling system. Install Energy Star appliances and WaterSense plumbing fixtures.

If you wish you lived in a “recycled” home, get to know your local salvage yard. Many communities have “architectural salvage” shops and recycle/reuse areas in their landfills. When you do your next home improvement project, go shopping at your landfill first. This is not only great for the environment; it’s also great for your budget. Plus, you’ll end up with a creative, unique home. (Of course, make sure that you don’t re-use items containing lead, asbestos, or other contaminants.)

If you wish you lived in a New Urbanist community, start walking and biking in your own community. Experiment with replacing some of your car trips with walking or biking trips. If you find that your community isn’t pedestrian- or bike-friendly, work with local politicians to change this. Learn about your local public transportation options to see if you can fit them into your lifestyle. If you’re in the market for a new home, make location and proximity to work and shops a primary consideration.

If an “ultra-small” home looks like fun but seems impractical as a long-term residence, consider reducing the size of your own living space. If your kids are grown, it may be time to downsize to a smaller home that uses less energy. If you’re building a new home or an addition to your current home, build only what you need. Sometimes the greenest building decision you make can be deciding to build less.

(The “Not So Big House” website (http://www.notsobig.com) is a great resource for those interested in downsizing while maintaining a high quality of life.)

Will My Air Conditioning Work Better with Dehumidification? A Question From Bergen County

September 14th, 2011

There are a number of common misconceptions in Bergen County and everywhere about humidity and air conditioning and how one affects the other. In truth, humidity is a major part of the discomfort we feel when the mercury rises. It can be 78 degrees outside but feel miserable simply because the humidity is high. So, many people wonder whether a dehumidifier is a good solution to moderate heat and how it will work in tandem with an air conditioner.

Humidity and Your Air Conditioner

First, remember that air conditioning naturally lowers humidity because it cycles air through its condenser and evaporator coil. Conditioned air is naturally lower in humidity, regardless of what’s going on outside. So, if it is hot outside and humid, an air conditioner alone is very effective. On the other hand, a dehumidifier is useful is when the temperature isn’t that high but the humidity is.

Dehumidification not only lowers the relative humidity in your home, it reduces the need for cooling because you will feel more comfortable. Not only that, but a dehumidifier costs significantly less to run. So, when the temperature outside isn’t that high, there is no need to use thousands of watts per day of electricity just to stay comfortable.

This also reduces the overall wear on your air conditioner. Since it doesn’t need to run 24 hours a day to reduce humidity, wear and tear on the device is reduced and you save a tremendous amount of money on repairs and eventual replacement costs.

When to Use a Dehumidifier Alone

Generally, the Department of Energy recommends setting your air conditioner to 78 degrees and using a combination of a dehumidifier and fans to stay cool while it is off. If the temperature rises above that level, the air conditioner will turn on and supplement your dehumidifier. Consider too that a dehumidifier will reduce the burden placed on your air conditioner to pull humidity from the air. Humid air takes more energy to cool than dry air. Despite the fact that dehumidifiers will often raise the air temperature by 1-2 degrees, they save energy and make you more comfortable.

So, if you’re looking for a way to reduce your energy bill and enhance the longevity of your air conditioner, look no further than a quality dehumidifier.

How to Use AC Most Efficiently in New Jersey

September 7th, 2011

Air conditioning is definitely something most of us wouldn’t want to try and get through the New Jersey summer without. And for a lot of people, because of medical or other conditions, it’s an absolute necessity. But just because you need to run your AC unit all summer doesn’t mean you need to suffer under the weight of astronomical cooling costs.

So if you’re interested in ways to save on cooling without sacrificing comfort, here are a few tips to get you started:

  • Get a Programmable Thermostat – When you come home at the end of a long day, you want your home to be cool and comfortable. But if you only have a basic thermostat, you would have to leave your air conditioning on all day in order to make this possible. Paying to cool an empty house is probably the last thing you want to do. But what is the alternative?Programmable thermostats offer the best solution in a case like this. These devices can be easily integrated into just about any home air conditioning system and they allow you to set different temperatures for different times of the day. That means you can have your air conditioning off while you’re not home and set it to come on a half hour or so before you get there. This way, you get the pleasure of walking into a cool, comfortable house without paying extra to keep it that way when you’re not home.
  • Incorporate Passive Cooling – The design of your home and how you use it can also have an effect on how hard your air conditioning system needs to work. Taking steps as simple as closing the blinds to block out the afternoon sun, putting up awnings and making sure that the exterior of your home is painted a lighter color to reflect sunlight rather than a darker one that will absorb it are all excellent ways to reduce the load on your air conditioner.
  • Supplement Your System – You can also take a good chunk out of your cooling bills by using things like ceiling fans in conjunction with your air conditioner. A ceiling fan can effectively lower the indoor temperature several degrees on its own, allowing you to set your thermostat a little higher.

Air conditioning is a major expense that most of us are resigned to paying, but there’s no reason to pay more than necessary with so many strategies available to save money.

What Features Should I Look for When Buying an Air Conditioner? A Tip From Waldwick

August 31st, 2011

There are so many different types and styles of air conditioners on the market these days in Waldwick, it can be difficult to figure out what features are worth paying attention to when it comes time to buy one for yourself.

Of course, the most important thing to do is make sure you get an air conditioner that’s appropriately sized for the space you’re trying to cool. But what should you look for beyond that? Here are a few features you might like to have on the unit you purchase:

  • Energy Efficiency – The more energy efficient your air conditioner is, the less your cooling costs will be. It’s as simple as that. So when you’re evaluating devices, remember that it’s worth paying a little bit more up front for a more energy efficient unit. It will save you money in the long run and you’ll be doing your part to help the environment.
  • Dehumidification – Just about every air conditioner controls humidity to a certain extent in addition to cooling. But some do this better than others. There are also air conditioners with separate dehumidification settings for those days that are more humid than hot. Even when you need both cooling and dehumidification, it’s nice to have control of each of these independently.
  • Timer – Being able to program your air conditioner to switch on and off at different times of day is more than just convenient; it will save you money. You don’t want to leave your air conditioner running all day when you’re not home, but it sure is nice to come home to the comfort of an air conditioned space. If your air conditioner has a timer, you can have both. Just set the unit to come on a half hour or so before you get home and you’ll enjoy cool, refreshing indoor comfort right when you get home without paying through the nose to keep your home cool when no one is there.
  • Easy-to-Use Controls – As simple as this one seems, you might be surprised at how inconvenient the controls on some air conditioners can be. So when you’re evaluating your options, make sure you research how easy each unit is to operate. This can definitely save you from plenty of frustration in the long run.

Air conditioners come in many different shapes and sizes. To make sure your decision works best in your home, do your research well in advance. And if you need help, talk to an air conditioning professional.

Saving Energy with Air Conditioners in New Jersey

August 24th, 2011

Air conditioners can definitely make it easier to get through a particularly hot and sticky summer in New Jersey. But they are also pretty expensive to run, especially if you live in an area with long, hot summers. Fortunately, there are quite a few things you can do to help your air conditioner keep your home cool without running up those astronomical energy bills.

  • Think about Your Thermostat – Most people set their thermostat at one temperature and leave it there. But does it really make sense to pay to keep your home cool all day long when no one’s home? Instead, try turning up the temperature when you leave the house and then again at night before you go to bed. It’s likely you won’t notice the difference and even an adjustment of a couple of degrees can make a big difference.
  • Multiple Climate Zones – When you are home, of course, you want to set your thermostat to a temperature you’ll be comfortable with. But that probably still means you’ll be cooling a lot of empty space. Installing a multi-zone system allows you to set different temperatures for different parts of your home. You can keep the spaces you use regularly cool and comfortable without wasting money paying to cool the unoccupied parts of your home.
  • Ceiling Fans – It might seem silly at first glance to use a ceiling fan at the same time as an air conditioner. But the truth is that using a ceiling fan to compliment your air conditioning system can actually save you a lot of money. Ceiling fans use next to no electricity to operate and they can make the house feel a few degrees cooler. With that added help, you can turn your thermostat up a few degrees without sacrificing indoor comfort and save yourself quite a bit of money – more than enough to cover the cost of running the ceiling fan.
  • Keep Things Sealed – Making sure your house is well sealed and insulated is another important way to keep your energy usage down during the summer. The more cool air that escapes, the harder your system has to work and the more energy it will use.
  • Proper Maintenance – Keeping up with the recommended maintenance for your air conditioning system is the best way to make sure it maintains the highest possible level of energy efficiency. Over time, it will ensure your system stays efficient longer as well – well beyond the initial lifespan estimates.

Why Install a Ductless Air Conditioner? A Question From Bergen County

August 17th, 2011

As you explore your options in terms of a new Bergen County home air conditioning system, 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. Instead, 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.
