Understanding House Ventilation Options

Wednesday, June 29th, 2011

All the fancy air quality control tools in the world are useless if you don’t have a good ventilation system to circulate air through your home each day. An air filter removes larger particles like dust, dander and pollen, and an electronic air filter removes smaller particles like bacteria, mold, and gases. However, your indoor air will still be poor without a fresh supply of air constantly circulating in from outdoors.

Types of Ventilators

There are a few options here, depending both on the number of contaminants your home has and the amount of heated or cooled air you are willing to lose each day through vents.

The simplest method is an exhaust fan. Fans blow air from your home, creating a negative pressure zone inside. Air inlets then allow new air to enter your home and equalize that pressure. There are also balanced exhaust fans – one fan blowing indoor air out and another fan pulling fresh air in. If you have open flames or gas burning appliances, a balanced exhaust fan is necessary to keep the flames from going out due to the negative pressure caused by a single outlet exhaust fan.

Traditional ventilation, while simple, is also inefficient. In the middle of winter it blows all of your heated air outside and in the summer, it does the same to your cooled air. Your home comfort system likely can keep up with the loss of heat or cooling, so you won’t be less comfortable, but you will certainly pay more on your energy bill.

That’s why heat and energy recovery ventilators are popular in many homes. Especially if you went to the trouble of having your home sealed up tightly to minimize energy loss, these ventilators will save you money.

When air is ventilated through a recovery unit, the energy and heat is transferred between indoor and outdoor air as it passes. In the winter, this means the energy in your indoor air is retained and during the summer, the energy in outdoor air is removed before it enters your home.

Which Method is Best?

The method you choose will depend largely on your current cost of heating and cooling and what types of contaminants you face. Energy recovery ventilators have the added benefit of patching directly into your indoor air quality units, so you won’t need to worry about new contaminants coming in either.

What Is a Flapper Valve?

Monday, June 27th, 2011

Your toilet is not an overly complicated piece of equipment. But in order to work properly, it does require that all of its parts are in the right place and in good shape. Even if something small on your toilet is out of place, it can cause problems like constant dripping or running, improper flushing force or a sudden refilling of the bowl when no one has flushed the toilet.

These problems can sound serious, but many of them are quite easy to address if you know where to look. With most toilets, that place is the flapper valve. The flapper valve is a relatively small rubber plug that fits over an opening at the bottom of your toilet tank. When you press the handle to flush your toilet, the flapper valve lifts up and allows all of the water from the tank to go rushing into the bowl.

The force of this water pushes everything out of the bowl through the drain at the bottom, clearing the bowl and refilling it with fresh water all at once. As long as the flapper valve is able to maintain a tight seal, this process will go along smoothly without a hitch. But sometimes these valves become dirty or simply wear out.

When that happens, water can begin to leak down from the tank into the bowl on an almost constant basis. Depending on the severity of the leak, this may just cause the toilet to run constantly. Or it can even cause periodic “phantom flushes” were the toilet clears the bowl without anyone pressing the handle.

Phantom flushes occur because too much water has seeped down from the tank into the bowl. When the volume in the toilet bowl reaches a certain level, the water in the bowl is forced out, resulting in a flush. This wastes water and can also be pretty startling if you are not expecting it. Fortunately, though, you can usually fix this problem easily enough.

To do this, check your flapper valve to make sure it is keeping a tight seal with the bottom of the tank when not in use. If it is not, you may only need to clean it off to restore the integrity of the seal. In more serious situations, however, you may need to replace the flapper valve entirely. This is not difficult or expensive and can save you a lot of water in the long run.

How to Choose the Water Softener That Is Right for You

Friday, June 24th, 2011

If hard water is a problem in your home, the solution may be simpler than you think. There are many water softeners out there, and some of them can be quite effective at treating the water coming into your home in order to remove the minerals that make the water hard. However, there are plenty of distinct differences between the various products on the market as well, so you should take a closer look at your options before you commit to one system over another.

The first thing you need to know when you start looking at water softeners is how hard your water actually is. If your water is very hard, you will need a heavy duty water softener. But if there are only moderate amounts of calcium and magnesium in your water, you may be able to opt for a less powerful model.

You should also be aware of how much water you go through on a daily basis. You want to get a water softener big enough to handle the demands of your household, and you will not be able to do that if you do not know how much water you typically use.

Another difference between the various water softener models on the market today is the type of regeneration cycle they employ. You can opt for a timer regenerated water softener that will complete the regeneration cycle as often as you set it to. These models tend to be cheaper initially, but they can also cost more to operate and maintain in the long run because they will regenerate when the time comes whether it is actually necessary or not.

There are also meter regenerated water softeners that only go through a regeneration cycle once a certain volume of water has passed through them. These water softeners are specifically calibrated to the amount of calcium and magnesium you have in your water so they only go through a regeneration cycle when it is absolutely necessary.

One concern that many people have about using water softeners is that the most common types use sodium as a regeneration agent. That means that they exchange sodium for the calcium and magnesium in the water. If you need to limit your sodium intake, you may not want to be adding even this small amount to your water. In that case, you can purchase a water softener that uses potassium rather than sodium which can be just as effective at removing other minerals.

Types of Drinking Water Filters

Wednesday, June 22nd, 2011

There are not many things more important than making sure that your home drinking water supply is safe and free of contaminants. All kinds of things can appear in your drinking water, and it is helpful to know exactly what types of contaminants are prevalent in your area so that you can make the best decision about what type of water filters to buy.

Some water filters work well at removing certain types of contaminants but not others. However, there are some good water filters that can get rid of almost all contaminants on their own. One such type is a distiller. Water distillers operate by heating the water coming into your home until it turns into steam. When water evaporates like this, it leaves behind anything it was carrying with it when it was in liquid form. The steam rises and moves into another chamber, and when it condenses back into liquid form again, the contaminants are no longer present.

Another type of water filter that removes the majority of contaminants is a reverse osmosis filter. These are excellent for removing things like asbestos, minerals, metals, salts and nitrates. For best results, however, you will want to purchase a system that incorporates some type of carbon filter as well. Carbon filters, placed either before or after the osmosis filtering system, are better at removing things like pesticides and radon. The combination of these two water treatment types into one filter system makes the solution more complete.

If you do not think you have a serious contamination problem but just want to get rid of bad tastes or smells in your water, activated carbon filters are a good and economical choice. However, you will want to make sure that you know exactly what contaminants the filter you purchase is designed to remove, as not all carbon filters are equally as effective against certain types of contaminants.

The most important thing to do before you go out and purchase a water filtration system, however, is to determine what exactly you are trying to remove from your water. The types of contaminants found in your water will vary a great deal depending on where you live and what types of pipes you have in your home, and that will directly affect the type of water filter that is right for you.

Water Filtering Faucets

Monday, June 20th, 2011

The last thing you want is to be drinking or cooking with contaminated water. Of course, you can always opt for a full house water filtration system, but these are often expensive to install and maintain. If you are not prepared to make this kind of investment, you may want to consider purchasing a water filtering faucet instead.

Unlike large point of entry water filtration systems, a water filtering faucet treats the water at one particular sink or other outlet. These types of faucets typically employ carbon filters that effectively remove many gasses and particles suspended in the water as it moves through the filter.

Just like any other type of water filtration system, there are various types of water filtering faucets and they are not all equally effective at removing contaminants. Before you purchase anything like this, however, you should make sure you know exactly what contaminants are present in your water. This is the only way to ensure that you purchase a product designed to treat exactly the problem that you have.

If you do decide to go with a water filtering faucet, make sure you know how often to replace the filters inside it and what type of replacements to get. Your water filter will only work properly when it is correctly maintained, and there is no point in using it if you have not been able to keep up with proper filter maintenance and replacement.

Another nice feature of water filtering faucets is that you can usually switch them on and off. When you need water for cooking or drinking, you can send it through the filter, and when you are using water for other things, you do not need to use the filter at all. This can cause the filter to last longer and it is also more convenient on models that have a reduced water pressure when the filter is employed.

You may initially balk at the cost of a water filtering faucet, preferring to purchase bottled water for drinking instead. But you have to take into account the fact that once you purchase a water filtering faucet, you will not have to spend the money on bottled drinking water any more. This will translate into a significant savings over time, making the initial investment well worth it in the end.

Maintenance: Cleaning Your Conditioner Coil Will Save You Headaches Later

Friday, June 17th, 2011

You have plenty of things to clean all over your house. But do you really have to clean your air conditioner too? Well, if you want it to keep working well, you do. In fact, cleaning the coil of your air conditioner is a quick and easy process, especially if you do it on a regular basis, and it can save you a great deal of frustration later on.

Like any machine, your air conditioner needs a tune up from time to time in order to continue to function properly. While a lot of this is taken care of if you have an annual maintenance service performed by a professional, your air conditioning coil will benefit greatly by being cleaned more often than that.

In fact, during your annual maintenance visit, your air conditioning technician can easily demonstrate for you how to get to the coil and clean it. This is a relatively easy task that you can carry out every month or so when your system is in use to help ensure optimal health and functioning for your system.

Of course, your air conditioning system will still run whether you clean the coils on a regular basis or not. For now, that is. Allowing more and more debris to build up on the coil, however, can have a big impact on the overall energy efficiency of your unit. An air conditioner with a dirty coil will have to work harder to keep your house cool, and that will be reflected by an increase in energy consumption.

Also, an air conditioner with a dirty coil that is having to work harder to keep your house cool will wear out more quickly than one that is working properly without added impediments. The added wear and tear that this causes to various other parts within your air conditioner can cause them to malfunction and need to be replaced sooner than they should.

This means more costly repairs, even if they are minor ones. It also means that your entire air conditioning system will probably not last as long as it may have with proper care. You will have to replace it sooner, adding even more to the cost of having and running the equipment.

Cleaning your air conditioner coil regularly is a simple and effective way of helping to keep the entire system running smoothly and efficiently for many years to come.

How Much Will a High Efficiency Air Conditioner Save You?

Wednesday, June 15th, 2011

When it comes to your air conditioning system, the energy efficiency rating really does matter. While you may be paying a bit more for products with higher energy efficiency ratings to begin with, you will certainly save a significant amount on your monthly cooling bills in the years to come.

Before you can evaluate your options in terms of energy efficient air conditioners, however, you will need to know how their efficiency is represented. Most air conditioners come with what is called a seasonal energy efficiency rating (SEER). A higher SEER means a more energy efficient model, and likely a higher price tag as well.

But how much more energy efficient is a SEER 10 air conditioning unit as opposed to a SEER 11? Well, the truth is that it is about 7% more efficient. However, a SEER 14 will be 23% more efficient than a SEER 10, but only 5% more efficient than a SEER 13 model.

While all of these numbers can help give you some context in which to evaluate the various air conditioners out there, they can only go so far. Turning these percentages into dollars is what you really have to do when you are trying to figure out what your monthly or yearly savings will be.

So to give you a bit of perspective, imagine that your annual cooling costs come to around $480 with your current SEER 10 air conditioning system. If you choose to upgrade to a SEER 13, you will save somewhere in the neighborhood of $110. But if you opt for the SEER 14 instead, you will gain an annual savings of closer to $140 compared to your current bill.

Of course, the SEER of a particular air conditioner is not the only thing that will cause the price of the unit to rise, nor is it the only thing that can cause your monthly cooling costs to rise. Air conditioners also need to be matched to the size of the space they will be asked to keep cool.

If the unit you have is too small to effectively cool the area in question, you are likely paying more than necessary in terms of cooling costs for less than ideal results. Similarly, if your unit is too big, you will be paying too much no matter how high a SEER rating it has.

What Is New in Air Conditioning?

Monday, June 13th, 2011

There are developments being made in air conditioning just about every day. This is a huge business, and so manufacturers are constantly trying to outdo each other as it is their only way to compete for customers. What this means for you as a consumer is that you will always have an excellent selection of products from which to choose.

Energy efficiency is one of the main selling points for any air conditioning system. For that reason, manufacturers are constantly working to come up with new and better models. The most advanced air conditioning systems on the market have energy efficiency ratings that by far surpass what was available even ten years ago and it is only going to keep getting better.

Another type of air conditioning system that is relatively new but is rapidly gaining in popularity is the ductless mini-split system. These and other compact air conditioners are popular because they can be installed virtually anywhere and do not take up much space. They also do not require the duct system that many other central air conditioners do.

In this way, ductless mini-splits combine the best of central air conditioning and more conventional window or wall mounted units. They keep individual rooms of your house cool and comfortable and can be controlled independently of one another, but they are also very quiet and energy efficient. In fact, ductless mini-splits are among some of the most energy efficient options available in the air conditioning world today.

For many years, enjoying the comfort that air conditioning provides has meant putting up with the noise of the compressor as well. Now, however, you can get the best of both worlds. Many air conditioning companies, in response to customer requests, have been working to curtail the noise and vibrations that air conditioners make.

This has affected models all up and down the line. Whether it is a window mounted unit you are after or a large central air conditioning system, you can rest assured that the model you buy today will be much quieter and produce a great deal fewer vibrations than your old system.

This is not only good news for you. It can also help to make your relationship with your neighbors a bit friendlier. The outside component of most air conditioning systems is usually where all the noise and vibrations come from anyway, and so your neighbors are likely to hear and feel it as well.

What Is Mini Split Air Conditioning?

Friday, June 10th, 2011

If you are in the market for a new air conditioning system, you have probably heard about the mini split systems that are becoming more and more popular these days. However, without more information, it can be difficult to determine whether or not this type of air conditioner is what you really need to keep your home comfortable all summer.

Mini split air conditioners, like most other conventional home air conditioning systems, are made up of two components. They have an outdoor condenser and an indoor unit that manages the airflow throughout your home. But the main thing that sets mini split systems apart from other types of home air conditioning systems is that these two component parts are connected by refrigerant lines rather than air ducts.

In a conventional air conditioning system, the outdoor condenser cools the air and then transfers it through air ducts to an indoor air handler. That air handler then takes care of distributing the air throughout your house via a larger series of air ducts.

Mini split systems, on the other hand, do not require air ducts to get the job done. Instead, these types of air conditioners make use of a wall mounted unit indoors to both cool and circulate the air after receiving coolant from the compressor outside. These wall mounted systems can typically handle the cooling load for one or two rooms and there can be more than one indoor unit hooked up to the same outdoor compressor, allowing you to cool your entire house in this way.

What makes mini splits attractive to many people is the fact that they do not require the installation of complicated ductwork to function. If your home does not already have ducts in place, adding them can dramatically increase the cost of putting in a central air conditioning system. Plus the work will take longer and is likely to be a larger disruption in your life.

Putting in the refrigerant lines for a mini split system, on the other hand, is much easier and cheaper. Plus, refrigerant lines can often reach into places that larger ductwork cannot. This allows you to provide air conditioning to parts of your house that previously did not have access to it. Also, mini split systems allow you to control the temperature in the various areas of your house independently of one another, making it possible to save quite a bit on your cooling bills every month.

Ice in Central Air Conditioning: Why Is This a Problem?

Wednesday, June 8th, 2011

If your air conditioner does not seem to be working as well as it should, your natural first reaction is to go out and take a look at the compressor to see if there is anything you can do quickly to correct the problem. Of course, you cannot assess the situation unless you know what you are looking for. For instance, if you see ice forming on the condenser coil or anywhere else on the air conditioning system, you will know you found the likely source of the problem.

Ice can form in your air conditioner for a number of reasons. The most common one is that your refrigerant levels are low. Since this refrigerant is contained in a closed system, a deficiency in refrigerant means that there must be a leak somewhere in that system. Only a certified professional can refill your refrigerant and determine where the leaks are in the system to make the necessary repairs.

Another reason that ice can develop in your air conditioner is because the air is not flowing fast enough through the system and across the coils. This can happen because of a problem with the fan or because there is an actual physical impediment to the air flow. Regardless of the reason, the ice will form because without adequate air flow the condenser coils will get too cold.

These coils are typically kept just above freezing by the constant flow of air across them. When the air passes by them at this temperature, the moisture from the air condenses on the surface of the coil. But because the coil is not quite freezing, the water then runs down into a collection pan. When the coil is too cold, however, the moisture from the air will freeze on the coil before it can run off.

This ice actually manages to insulate the coil and keeps it from properly cooling the air or removing any additional moisture. If left unattended, the ice in your central air conditioning system can cause real damage to the unit. Plus, it is not allowing the air conditioner to do its job and cool your house down. So if you notice any amount of ice at all beginning to form on any part of your air conditioner, be sure to call for professional service right away.
