Is Your Home More Valuable with Energy Efficient Appliances?

Monday, September 12th, 2011

It’s impressive the things people do to improve the value of their Tualatin home. We’re talking about crown molding, new floors, new siding, upgrades to the landscaping and much more. The cost of upgrading these things can grow out of hand quickly and if the boost to your home’s value isn’t equally exponential, it’s hard to justify the expense.

So, it’s always nice to find a simple upgrade that can be performed for a few hundred dollars that will save you money immediately and improve the value of your home in the future. Your appliances are one such upgrade.

The Value of Energy Efficiency

An energy efficient washing machine can save upwards of $150 per year on water costs. An energy efficient toilet cuts consumption by as much as 150%. Low flow shower heads cut water costs by one third to one half and your heating and air conditioning systems can be improved by 10-35% depending on the upgrades available to you.

When you add up all those savings, the result is a tremendous amount of money that can be saved each year on everything from your water bill to your cooling needs. Imagine what happens when someone looks to buy your home. They see that there are all new appliances with energy efficient ratings that will save them money.

It’s not just lower bills; it’s a decrease in upfront investment. On the surface, it’s unlikely that your energy efficient appliances will directly increase the value of your home, but they can increase the likelihood of someone paying what you’re asking for the home. They add value to the livability of the home, if not the property itself and in today’s housing market, that’s a major plus.

Best Upgrades

The best upgrades to your home’s appliances are the ones that save money without additional work. Major upgrades to your heating and cooling are good if you need an upgrade anyway or you plan on staying in your home for a few years.

The Energy Efficiency Rating of Central Air Conditioners: Why is this important?

Wednesday, August 24th, 2011

When you are shopping for a central air conditioning system in Estacada, you will have to evaluate your options based on a number of different factors. For instance, you will need to decide which type of system is the best match for your home and for your particular cooling needs. It is also important to make sure that the central air conditioner you choose is the right size for the cooling load it will have to take on.

However, it is also very important to evaluate your central air conditioning options based on how energy efficient they are. This will have a great deal to do with how much you pay in terms of cooling costs each month, which makes it easy to see why you should take it into account before you make a purchase.

The energy efficiency of a central air conditioner is generally expressed as a seasonal energy efficiency rating, or SEER. The SEER numbers you will typically find on the latest air conditioning systems range from eight to 19.5 with the higher numbers signifying a more energy efficient model.

So it is pretty easy to figure out that a central air conditioner with a higher SEER will save you some money monthly because it will use less energy to get the same job done. But central air conditioners with high SEERs also typically have high price tags. So to determine how high of a SEER you need, you will need to know more exactly how much more money you will save as you move up in the rankings.

You can do this by comparing the SEER of the system you currently use with the new system you are considering and compare how much your current energy usage would cost you with each model. Basically, you want to pick a central air conditioner that will save you enough to offset the purchase price of the unit.

Often, this means that you will be best off with a SEER 14 or SEER 16 because these units save you a considerable amount over older models without carrying too high a purchase price. However, the amount you save will be directly related to how much you use your central air conditioning system, so if you live someplace that is extremely hot for a large chunk of the year, it may be worth it for you to buy a very high efficiency air conditioning system.

Does Humid Air Affect How AC Runs?

Friday, August 19th, 2011

You’ve probably heard a dozen times that humidity is removed by air conditioning. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in their Canby home. But, did you know it costs significantly more to remove humidity from the air with air conditioning than with a dehumidifier? Here’s why.

Water Vapor in Your Air Conditioner

Consider the amount of energy it takes to raise the temperature of water by one degree – one BTU. However, to change water from liquid to steam, another 10 BTUs are required. So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.

The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner every day (at least not early and late in the summer). Imagine, the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs

Another thing to consider is that humidity can actually put an extra burden on your air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill but eventually on the machine itself.

The added pressure will result in eventual breakdown of the system and a need for early replacement. The easiest solution is to purchase a dehumidifier. These run at a fraction of the energy level of a full AC system and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, you may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.

Air Conditioners and Humidity: How do they coincide?

Friday, August 5th, 2011

Ever wonder why all of those air conditioners hanging out of people’s windows in Wilsonville 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.

What Are Limit Switches and How Do They Work?

Friday, July 29th, 2011

When you set the thermostat on your air conditioning system, you pretty take for granted that the system will maintain that temperature throughout your house. But did you ever stop to think about how it’s actually accomplished? The truth is that there are many moving parts that all play a role in keeping your home cool and comfortable, and one of these is the limit switch.

What Is a Limit Switch?

Although you’re probably not aware of it, you’ve encountered plenty of limit switches over the years. A limit switch is anything that stops an electric appliance under certain circumstances. The little switch that turns the light on in the refrigerator when you open the door and then off again when you close it is the perfect example of a limit switch. Another common one is the switch that stops your washer or dryer from running when you open the door. Limit switches are used for a variety of appliances and gadgets to not only save electricity but to keep you and your device safe.

Limit Switches and Air Conditioning

The limit switch on your air conditioning system is the link between the blower on your air handler and the thermostat. When the thermostat senses that the desired indoor temperature has been reached, it stops the air conditioner from producing any more cold air. At that point, it’s important for the blower to stop functioning as well.

If it doesn’t, the blower will continue to move and warm air rather than cold will begin circulating throughout your home. However, if the blower shuts off too soon, the cold air that’s still being generated by the air conditioner won’t be able to circulate. So it’s essential that the blower be switched off at the same time the cold air stops arriving. That’s exactly what the limit switch does.

While it’s only one very small part of a large machine, the limit switch in your air conditioner plays a vital role in keeping your home comfortable and in allowing your air conditioning system to function as efficiently as possible.

If you notice that your air conditioner is shutting off too soon or not soon enough, it may be because of a broken limit switch. Sometimes, the system simply needs to be reset, something you can do with the help of your owner’s manual. However, if your limit switch is broken, you should contact a professional to take a look and determine if it needs to be replaced.

IAQ Systems – Can They Help Get Rid of Bed Bugs?

Monday, July 25th, 2011

Indoor air quality systems are designed to remove a lot of unwanted contaminants and allergens from your home. But, they can also help remove some unwanted pests. Dust mites, for example, can only survive in humidity of 50% or greater. But, what about bed bugs – a much larger problem for many homeowners? Can you get rid of them with your air quality system?

Bed Bug Facts

Bed bugs come into your home on clothing, luggage or other people. They don’t sprout out of any one particular condition, so no matter how clean your house is, you can be exposed to bed bugs at work, on the train, or when visiting friends. Once you’re exposed, it is very easy to bring them into your home where they quickly spread to the rest of the family.

Bed bugs don’t generally live far from people, so you won’t find them in dirty ducts or hiding in your air vents very often. That makes it even harder to get rid of them without a full blown fumigation of your home. However, there are some things your indoor air quality system can do that will make a difference.

Indoor Air Quality Actions to Take

Bed bugs don’t just thrive on your family, but on the conditions in which you live. They’ll get into the nooks and crannies of your furniture and your clothing and wait until night fall to come out and bite. So, one of the easiest things you can do is utilize a complete air filtration system to remove all the extra debris and dust that builds up in your home.

Humidity control will also make it easier to clean your mattress and the surrounding areas with a HEPA certified vacuum cleaner. If you have ductwork, make sure it is cleaned regularly. While bed bugs don’t hide in duct work very often, some will and every bed bug you can destroy is one less that will bite you.

Finally, avoid any pesticides while your family is in the house. Pesticide exposure is a common cause of illness in children and pets. It can be avoided with careful attention to indoor air quality and cleanliness. If you need to fumigate, call a licensed exterminator who can do so without putting anyone in your home at risk. They can help you layout a good fumigation plan and block future infestations.

Maintenance Really Does Save Money

Monday, June 20th, 2011

When it comes to your home heating and cooling systems, you really cannot go wrong with proper annual maintenance. While it may seem like an unnecessary expense, especially if your systems are relatively new, you will save a lot in the long run if you pay that small fee once a year for each system.

During a maintenance visit, a technician can thoroughly clean out your heating or cooling system and check all parts to make sure they are not showing signs of excessive wear and tear. If they do find a problem or a part that needs to be replaced, they will be able to make the necessary repairs quickly and you will not have to worry about calling someone out later for an emergency visit.

Also, catching problems early like this means that repairs will likely involve fewer parts and cost much less than they would if you let the problem go and it became more widespread. The truth is that your heating or cooling system can continue to work when one or another of its parts is not working correctly, but that means that other parts of the system have to work overtime to create the same result.

Your heating or cooling system will also be much more energy efficient if it receives regular tune ups and attention from a professional. Even the best new systems lose a small percentage of their efficiency each year that they are in operation. While this is not much from year to year, the cumulative effect will soon cause your energy bills to climb higher than necessary.

Paying for regular maintenance, then, can actually save you money because it will mean you pay less each month to run your system. And it is never too late to start. Even if your heating or cooling system is not new, it will benefit from a thorough cleaning and tune up. You may be quite surprised how much your energy bills go down after this type of service has been performed.

Annual maintenance can also help you to get more for your money by extending the useful life of the heating or cooling system. Many systems that are properly maintained can last even beyond their expected life span, meaning that you will not have to replace it as soon as you would have otherwise. For all of these reasons, the minimal cost of an annual maintenance visit is well worth paying over the long term.

What to Do if Your Ceiling Fan Does Not Work

Friday, June 10th, 2011

A ceiling fan is a great addition to your home. It can keep you cool all on its own on moderately warm days and it will help to take on some of the cooling load even on days when you do need to use the air conditioner as well. Plus, you can even use your ceiling fan in the winter to keep the warm air from your heating system circulating properly.

But just like anything else, your ceiling fan will encounter some sort of problem from time to time. While there are certainly some things that you cannot fix on your own, it is a good idea to check on a few items before you call in a professional repair person.

For instance, if you switch on the fan and nothing happens, make sure that all of the controls are in the place they should be. Most ceiling fans have a chain or dial on the body of the fan itself that controls the direction that the fan turns and can even turn it off. However, there is usually also a power switch on the wall. If you flip the switch and the fan does not turn on, there is a good chance that the setting on the fan itself is in the off position.

After ensuring that all of these switches and controls are calibrated properly, you can also take a look at the fuse and the breaker that the fan is connected to. If the breaker is thrown or the fuse is blown, the fan is not getting power and you will have to replace the fuse or reset the breaker to restore power to that circuit.

If that does not solve the mystery either, you may want to test the blades themselves to see if they seem to be stuck on a physical impediment. Ceiling fans do occasionally need to have their bearings lubricated and this is a relatively simple task that you can carry out on your own as well.

However, if none of these actions seems to solve the problem, then you will probably need to call in a professional to assess the situation and make the necessary repairs. There may be a mechanical problem within the fan itself or the wiring could be frayed or fused and these are not repairs you should attempt to make on your own.

Mold…What if I Have Mold?

Wednesday, June 1st, 2011

No one wants to find mold. But, even if you’re not aware of it, mold is probably lurking somewhere in the damp, dark crevices of your home. And mold is particularly likely to grow in homes with improperly regulated humidity. Luckily, because we know that, there are quite a few things we can do to stop the growth of mold in its tracks and save your home from unsafe air quality and the damaging effects of those little spores.

The Dangers of Mold

As mold grows, it can do damage to your woodwork and other areas of your home. It also contributes to indoor air quality issues because mold spores are a significant indoor air contaminant. Many people are allergic to mold spores, so if you or someone else in your household has experienced allergy symptoms that you can’t explain, mold spores are a likely culprit.

If you find out there is mold in your home, don’t panic just yet. There are some things you can do to address the problem and get mold out of your house for good. Your main task will be getting rid of the mold that is already there. This isn’t necessarily easy because of the areas mold tends to grow in. But, even with the proper air quality treatment, your home and health is still at risk if you don’t target that existing mold fast.

Stopping Mold in Its Tracks

Just getting rid of existing mold won’t solve the problem, though. Mold keeps coming back as long as there is an environment to support it – and that means moisture. Mold requires water to grow, so the chances are that if you have a mold problem in your home, you also have a humidity problem. Getting your indoor humidity under control will make it much easier to remove and keep mold out of your home for good.

There are plenty of good humidification systems on the market today. They can be easily integrated into your home heating and cooling system and provide great, consistent humidity control. Make sure you get one that’s large enough for your home. An indoor air quality professional can help you make that determination. Once you have a good humidification system in place, you’ll notice a huge difference in your overall indoor air quality, and hopefully the problem won’t return anytime soon.
