How to Shop for Energy Efficient Air Conditioners

Summer is the time for swimming, vacations, and racking up huge electric bills, if your old air conditioner is not energy efficient. Upgrading to a new unit, whether a central system or window unit, will help cut your bill while keeping you comfortable.

The key to shopping for a new air conditioner is knowing about energy ratings and what the mean for your budget and the environment.

According to Energystar.gov, the Energy Star program is a voluntary program where companies and individuals can work together to make and buy products with a mind to their environmental impact.

Established by EPA in 1992, under the authority of the Clean Air Act, the Energy Star logo is a familiar sticker on many appliances, particularly air conditioning units. EER stands for Energy Efficiency Rating, and the standard government rating is 9.8.

Many of the newer units have a EER of 110.8 or 11. These ratings apply to central air conditioning units as well as window and portable air conditioners. The best part is that purchasing an energy star unit can save you money at tax time too. As of this writing, federal tax deductions exist for purchasing energy saving appliances.

Central Air Conditioners

Central Air conditioners are quiet and take up less space than window and portable units. They also are more effective in keeping your house cool and comfortable. Unless you live in a tiny apartment, having central AC is the best practical way to cool your home. As it is a big-ticket expense, many homeowners delay putting out money for new unit; however, the money spent on a new central air conditioner unit will save money in the long run, so it is a wise investment.

Many of these units are designed to blow out of the central heating pump. What some purchasers don’t understand is that unless the blower exhaust systems in the heating unit is updated, the new system will not work as well as designed.

Window Air Conditioners

If you live in an apartment, or simply cannot afford central air conditioners, window units are the way to go. They also have energy star ratings. You need to keep the size of your window and the area you are cooling in mind to choose the best one. BTU’s stand for One British Thermal Unit (BTU) and stands for the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.

The Energy Star website has a handy guide to how many BTUs are needed to cool a certain sized room. For example, an 8,000 BTU Window unit would be adequate to cool a home office, but a larger unit would be needed for the living room.

Many homeowners who don’t opt for central air find that they can save energy and money by installing several smaller units around the home, and turning off the units in rooms that are not in use. A central air conditioning unit cannot be calibrated to only cool one room unless there is a separate thermostat unit in each room.

Portable Floor Air Conditioners

Portable floor rolling types of air conditioners do not work as well as central air conditioners, or even window units, but can be handy to roll out in an emergency if your central unit breaks down. A hose is attached out of the window for air exchange.

Looking for the Energy Star sticker and getting a unit, whether central or portable, to find an air conditioner that matches your home’s space, budget and cooling needs. Whether you are using air conditioning two months out of the year in Wisconsin or nine months a year in Florida, keep the environment as well as your pocketbook in mind to get the best deal.

Can HVAC UV Lights Help with Air Quality Issues?

Ultra violet (UV) lights have many uses. Many of them you’re probably not aware of. It can sterilize medical equipment, dry nail polish quickly, treat Vitamin D deficiency in people and sterilize different components in food production.

Recently, it is being incorporated in air conditioners. A good question to ask is if it really is worth it to pay extra to have them on our HVAC air handler. Does it really improve indoor air quality?

So, here’s a little bit of information about it that can help you make a decision for your home. UV lights are great in killing organic causes of air quality issues like bacteria and mold. However, they don’t do a lot against dust, pollen, pet dander and other allergens. So, it really depends on what the root cause of your low air quality is and how sensitive your family is to them.

Many people with allergies have a very strong sensitivity to a different allergens. UV lights are very good in killing mold so in general, it does have positive effects on the quality of your indoor air.

The Journal of Applied and Environmental Microbiology published a study in 2001, entitled “Effectiveness of Germicidal UV Radiation for Reducing Fungal Contamination within Air-Handling Units.” They cited that after only four months of operation, the fungal levels in a commercial building were reduced significantly.

Places like Florida, where high humidity and high temps create a breeding ground for mold and other microbes is a good example area to use UV lights.

How HVAC UV Lights Help Improve Air Quality

The lights are installed in the air handle of the air conditioner system. All molds within reach of the light will be killed. This means that the coil will remain mold free which is very important. Since air passes through the coils, mold spores and fungal particles will also be killed, thus purifying the air.

Should you install or not install?

To install UV lights in your HVAC system, you have two options. One is to purchase a stick light which you can attach near the return air duct. It can cost around $100 or more. It’s the most common system. The second option is to buy a whole system of air sterilization. The UV light cycles on with the air handler blower making it more effective than the stick light. These systems are also more costly. They can cost on average at least $1500.

The first option is good enough if you’re looking to keep the coils mold free. The latter option is best for those with allergies and need a better purification system.

How to Save Energy when Air Conditioning is a Must

There are some areas of the country where air conditioning isn’t just a convenience. When hot temperatures arise to triple digits, especially when such temperatures are combined with high humidity, public health can be affected. It’s always a good idea to have an air conditioner in the home for such times.

Air conditioning can be expensive, so it’s natural to want to know how to save energy when air conditioning is a must. Here are some answers to this question.

Use Air Conditioning Only When Needed

This may seem obvious, but the reality is that energy is often used mindlessly. How many times have you flipped a wall switch when entering a room, whether it was needed or not? The same is true for air conditioning. Instead of setting it at one setting and forgetting about it all summer, become more aware of how you actually use this power.

Most homes have a thermostat that indicates indoor temperature. When outdoor temperatures are lower than those indoor, take advantage of the free power offered to you by nature and open the windows. If you live in a ranch home, it’s likely that you have windows on both sides of the house. Open them to take advantage of cross ventilation. On days when you can’t open the window, keep shades closed to block as much of the sun as possible.

If you have a basement, consider furnishing it for use in the summer. Even before this, is it wise to understand if a swamp or evaporative cooler is needed. Avoid cooking with your oven on hot days. Switch to cooking in your microwave or slow cooker instead.
When you must use the air conditioner, set the temperature as high as possible. Experts recommend a setting of 78 degrees Fahrenheit as an average, to save money.

Install A Whole House Fan

One of the big problems in the summer is that heat becomes trapped in the home, making air conditioning essential when you’re trying to sleep at night. A whole house fan is an inexpensive way of solving that problem. It is installed into your attic floor to remove accumulated heat from the home in the evening while opening windows to bring cooler air inside. This has been proven to lower energy bills.

Install ceiling fans in the rooms you use the most.

This is a simple but effective solution as it provides comfort and efficiency during both day and night.

When You Are Away From Home

If you spend a large part of your day away from home, you may want to have a programmable thermostat installed. This allows you to program in your daily schedule so that air conditioning is cooler when you are at home to enjoy it.

When you go on vacation, set air conditioning temperatures high to save energy. It’s unwise to turn off the air conditioning if temperatures are expected to be hot, especially in areas where high humidity is a problem.

These are only some ideas for how to save energy when air conditioning is a must. The best tip by far is to become an alert energy user. Saving energy instead of wasting it thoughtlessly will help you save money while benefiting the earth’s natural resources.

Silent Air Conditioners

Most of us may wonder how our predecessors ever managed to get along without an air conditioner. Today an air conditioner is not only a convenience; in some climates, it’s almost a necessity.

The only problem with this invention of modern man is that it can be very noisy. The condenser and fan of the air conditioner can be so noisy it keeps one awake at night. Sleepers may be abruptly awakened as the unit cycles on and off. This is especially true for those of us who are noise-sensitive.

Admittedly, most of us hear noises at different levels, and what bothers one person may not bother another. Window-mounted or room-mounted air conditioners tend to be the noisiest, reaching about 60 decibels of noise, the same noise level as if someone was having a conversation in the room with you.

Apartment dwellers are often the most affected. That’s because their air conditioners are usually located indoors with them. Thankfully, manufacturers are tuning in to this specialized need, and providing what is called a “silent” or “quiet” air conditioner.

How Does A Quiet Air Conditioner Work?

All air conditioners emit some noise. However, a quiet air conditioner operates with a low hum instead of a loud mechanical noise. It is designed with a buffer that is located around the condenser to muffle the noise. The fan of the unit is also specially designed so that it works more efficiently and silently.

How will you know if an air conditioner you want to buy is a quiet model? There are units that are specifically branded this way, so look carefully at the package. Unfortunately, most models don’t list the exact noise level of the unit, so check customer reviews to find out which air conditioner will best fit your needs before you buy.

It’s possible you may have to pay a little more for this feature; however, prices are coming down as demand increases. Certain manufacturers, such as Friedrich, are known for supplying the quietest air conditioners overall.

Quiet models come with other consumer-pleasing features that make them very attractive to buy. For instance, many models are energy efficient, and they have digital remote control of temperature.

Manufacturers who produce quiet air conditioners warn that it’s important to be certain your unit is properly installed. If it’s not, it will not operate as it should, and may be noisier than it is rated.

If A Quiet Air Conditioner Isn’t Quiet Enough

Some people are ultra-sensitive to noise. For such people, there is really only one good answer: locate the air conditioner outside. A ductless mini-split air conditioner does not require installation in a window and is much quieter because the condenser is located outdoors. All that it requires is a hole in the exterior wall, to route a pipe from the outdoor components to the indoor parts.

This can be a viable option for any homeowner who does not have central air conditioning and wants to keep the cost of air conditioning low. It has the added bonus that it can be configured as a source of heat as well as cooling.

Fortunately, none of us have to choose between keeping cool and getting a good night’s sleep. Silent air conditioners give us the best of both worlds.

History of Air Conditioning

Primitive Air Conditioning

For a long time, man has struggled to get comfort in different climates and seasons. Air conditioning happens to be one of the best inventions of man on that regard.

Air conditioning in its primitive form such as fans used in palaces has existed for a long time. They were, however, inefficient and expensive to use and acquire. This, therefore, limited their use to palaces alone and homes of wealthy individuals.

Until the 1900s, American also dealt with harsh weather conditions the same way common folks around the world did. Things began to change when electric fans were invented. These replaced hand fans that wealthy people were used, and slowly even the working class found it affordable to have one installed at home.

Basic Air Conditioning

The first real air conditioner was built in 1881 for a dying president. It involved blowing air through cotton sheets soaked in cold water. This was obviously an expensive technique. By the end of the two months, the system had consumed over half a million pounds of ice.

First Efficient Air Conditioner

The first efficient air controller was built in 1902 after Nikola Tesla invented alternating current motors. This made it possible to make oscillating fans. That is when a New York-based 25-year-old engineer named Willis Carrier made the first true air- conditioner. This device blew air thorough water-cooled coils. The unit was not invented with human comfort in mind. It was designed to make sure that a printing press was dehumidified. The process involved cooling the air to get rid of moisture from the warm moist air.

He then in 1922 followed it with a modification. He invented the centrifugal chiller to reduce the overall size of the unit. It was introduced in the Rivoli Theater, Times Square. This started the tradition of the blockbuster summer, where people would flock to air-conditioned movie theaters on hot summers.

Air Conditioner Revolution

Carrier’s invention set in motion the idea that air-conditioning can be applied to other living spaces and places of work. From the 1930s, air-conditioning spread from factories to departmental stores, offices, and rail cars, this sent summer productivity to new record heights. Residential cooling, however, took a little bit longer to catch on.

Up to as late as 1965, only about 10% of the total population had air conditioning at home. According to reports by Carrier Corporation, the home owners in the South slept on the porch. They also put their underwear in an ice box before wearing it. This changed over the years. By the year 2007, over 87 percent homes had air conditioning. Overall, this marvelous invention has led to Sun Belt cities becoming bearable during summers. They have therefore attracted big populations, creating the U.S long-term population shift.

Air Conditioning in the Rest of the World Today

The Europeans have been slow to take the concept of air-conditioning. It is, however, beginning to take root. In the developing world, data is scarce on the use of air-conditioning. The statistics show that air-conditioning is available in corporate offices, hotels, and restaurants. Staying in the shade and drinking cold water is a common technique of fighting heat in third world countries.

Samsung Air Conditioner Reviews: Samsung Split Air Conditioner

Samsung is a brand that is well known for providing some of the best smartphones and HDTVs in the market.

Through the years, this iconic name has decided to reach out to other products as well such as air conditioners.

At present, Samsung offers a wide range of split air conditioners that not only boast of high quality performance but also channels its signature sleek design.

This article will feature a summary of Samsung air conditioner reviews on their split air conditioner units.

One of the biggest and strongest selling points of a Samsung split air conditioner is its ‘eco-friendly’ feature. The brand has decided to design their brand thinking of air and water conservation, less power usage, and using parts that can be globally recycled. It also uses a R-410a refrigerant which is an eco-friendly one and reduces air pollutants and the usage of material with high global warming potential or GWP.

In terms of technology, Samsung’s split air conditioner units boast of an S-Plasma Ion technology. Their unit which comes with a feature called ‘Virus Doctor’ has the S-Plasma ion which functions by creating oxygen and hydrogen ions. These ions combine with harmful ions present in the air like OH radical, bacteria, and viruses and convert them into water vapor.

Now when it comes to its cooling capabilities, Samsung can be considered as a little more above average. Its split air conditioner units come with two features namely the maximum (turbo) cooling and even cooling function. The turbo cooling option enables the device to run at a maximum speed of 30 minutes and then cools down afterwards. The even cooling control, on the other hand, works by distributing the air evenly in the room.

One good feature of this air conditioner is that they assess the existing humidity and temperature in the room and self-adjusts in order to provide the most pleasing cooling environment in the area. This feature can be enabled when these air conditioners are set on automatic mode. It even helps in the reducing of energy usage as well.

Now with its looks, there is no doubt that Samsung also applies the sleek designs they are so well known for in their air conditioners. They offer units in a number of tonnage capacity and BEE Star ratings. They truly stand out from the usual pack of split air conditioners with its colored body (usually maroon)and  very stream lined design.

In terms of its cons, there are Samsung air conditioner reviews that complain about the brand providing bad customer service. Some people say that they have to constantly remind their service center about their request for repair and that representatives offer false and repetitive excuses whenever they fail to provide technicians. There were even feedbacks from customers complaining about their unit breaking down a couple more times despite of being repaired by service engineers from the brand.

In summary, Samsung’s split air conditioners can be considered above average in terms of performance, design, and features. Still, we cannot give a full okay to them because they weren’t able to meet the customer service needs of their users which is a very important aspect in air conditioners.

AC Repair Help – Simple Tips for Your Air Conditioner Repair

airconditioner-ac-repair-helpYour air conditioner breaking down is probably one of the worst things that can happen to you especially during the summer months. During this time, it is highly understandable for you to have the urge of calling your trusty repair service provider immediately. But do you know that checking your unit first can actually benefit you more than instantly turning to someone for help?

There are times when air conditioners break down from problems that only require some very simple do-it-yourself solutions. What if you really need a professional to fix your unit then? Checking out your air conditioner and determining what the cause of problem is can do you good. Not only will it lessen the time of repairing, you will also help the repairman bring the necessary tools and parts to solve the problem stat.

Here, we will enumerate some very simple tips for your air conditioner repair.

1. Do you feel like the thermostat of your unit is not functioning properly? Check the setting and compare it to your room’s temperature. If the setting is indeed lower than your room’s temperature, it means the cooling system is not operating well. Check the air handler then, also known as the indoor AC unit. Here, you can know if your fan isn’t functioning or if the dilemma is with the circuit breakers on the heat pump or handler.

2. If the fan is the only thing that is not functioning, then there is a high chance that a malfunction occurred in the handler’s control board or the blower monitor. If the heat pump’s fan is the one not operating properly, go on and check if there is any ice buildup on the pair of copper refrigerant pipes that you can see on the outside enclosure. If this is the case, simply turn off the heat pump for a couple of hours to let the ice melt.  This is actually one of the simplest kinds of AC repairs. However, if the pipes freeze again, then it is time to really call for an AC repair company.

3. Being low on coolant fluid is another common cause of a malfunctioning air conditioner. However, professional HVAC repairmen are the only ones allowed to replenish this fluid. If you are sure this is the problem, then it’s time to ask for an authorized air conditioner service repair company.

4. Check if the thermostat is really set on the ‘COOL’ function. Your air conditioner should also be plugged on a 240-volt circuit. Check if there are any tripped breakers or blown fuses on main and secondary circuit panels. If you see some of them broken, reset the breaker and simple replace the busted fuses. If, for some reason, the circuit blows again, then that’s when you call for your repair contractor.

Being familiar with these simple tips for the repair of your air conditioner is a must for every unit owner. Besides from hastening the process of your unit being fixed, you can save money by preventing yourself making unnecessary HVAC service calls as well.

Portable acs are much easier to repair yourself, especially if you buy a good portable air conditioner to begin with. You generally won’t need to call any repair specialists if you know how to use basic tools and can buy your own parts.
