Algae Growth in AC Drip Pan Can Damage Home

Some homeowners are unaware that water from their air conditioner can cause extensive damage to their home. An air conditioner cools and dehumidifies the home. The dehumidifying occurs when the moisture-laden air in the home passes through the evaporator or cooling coil. The moisture condenses on the cold coil and drips into the evaporator drip pan. A drain line carries the water to the sewer. This line may be rubber, metal or plastic.

Algae Grows in Warm, Stagnant Water

This works fine, unless the drain line becomes plugged. The opening into the drain line or the drain line itself can become clogged with rust, debris or algae. Algae tends to grow in warm, stagnant water. When the drain line is plugged, the water will overflow the drip pan and spread to the surrounding area. The drip pan is usually about one inch deep and overflows quickly.

Many cooling coils are located in the air plenum of the furnace in the basement. If the floor in the furnace room is concrete that slopes toward a floor drain, there is no serious problem. The overflow will run out the drain. In the absence of a floor drain, the water could spread over the whole basement and ruin carpet or floor covering.

Many Air Conditioner Air Handlers Are in Attics

With the cooling coil located in the furnace, the furnace fan circulates the cooled air throughout the home. In the absence of a furnace, an air handler unit containing a fan is used to circulate the air. To save space, it is often installed in the attic. In this situation, a plugged drain line would result in costly damage to attic insulation and to the ceiling. If repair is not immediate, floors and carpet would also be damaged.

Some homes, especially in warmer climates like that of Palm Beach county, have a combination heating and air conditioning unit located outdoors. The fan or air handler is located inside the unit. A plugged evaporator pan drain line would not cause damage inside the home, but the leakage is undesirable. It would create a wet area around the unit. Water accumulation inside the unit will cause rusting, and bacteria and spores from mold and algae will be circulated throughout the home. This can cause respiratory diseases and poor indoor air quality.

Window Air Conditioners are Not Immune to Plugged Drains

Window air conditioners can have the same problem. Their drip pans and drain lines need the same treatment as a central air conditioner in spite of its location, size, and installation. Although the pan overflow may not drain into the home, bacteria and mold spores can be circulated into the home as the air is pulled in through the A/C unit.

Regular Maintenance Can Largely Prevent Drip Pan Problems

Cleaning the drip pan and drain regularly is a good idea. Before opening the cover of the evaporator coil, always shut off the main power supply to the unit. Do not rely on the interlock switch on the door. Pour water down the drain. If it runs out slowly, the drain is partially plugged. Clean any debris from the pan. A liquid algaecide may be used for cleaning, but a strong solution of laundry bleach is highly effective for cleaning the pan and drain line. After cleaning, flush thoroughly with water. Do not mix bleach with other cleaners, as toxic chlorine gas can be released. After a thorough cleaning, algaecide tablets can be placed in the pan to inhibit algae growth.

The drain line must slope all the way to the drain. A loop that would hold stagnant water encourages algae growth.

When the technician performs routine checkups, be sure the drip pan and drain line are checked. Routine inspections by a certified air conditioner technician and minimum attention by the homeowner can virtually eliminate the possibility of disastrous water leakage of your central air conditioning system.

How To Choose Indoor Air Purifiers For Allergies

Often when people think of pollution, visions of giant factory smoke stacks billowing black air upwards come to mind. But indoor air pollution is just as harmful and is more common than outdoor pollution. It is something people generally do not think about often, until it is found that they or someone they love is having an adverse reaction to polluted indoor air.

Particles which tend to linger in the air are those which are most bothersome to most, especially if the inhabitants have either allergies or asthma. These two conditions have become more prevalent over the last several decades and will continue to increase unless the indoor air treatment strategy is changed to improve the quality of the ventilation system of one’s home.

Clean Air Is Important

Many overlook the importance of clean, high-quality indoor air, as well as the methods which they can take in order to improve it. A few of the main surface magnets for air particles include: floors, rugs, cushions, bedding materials, counter tops, as well as decorative items around the home.

This includes a wide range of various air filters and purifiers as well as size variations which can also range from one single room purifiers, portable purifiers, all the way to air purifiers which are attached to the entire home ventilation system.

Types of Indoor Air Purifiers

Portable indoor air purifiers are easy to move around and tend to be cheaper than some of the other types; however, they can be very noisy. If they are not noisy, meaning that they do not contain a fan, they will not work as proficiently or last as long. Portable purifiers are the most convenient type of indoor air purifiers because they may be moved accordingly in order to suit the needs of the environment which you are in.

Single room indoor air purifiers work really well when the user wants the focus to be primarily on one room, such as a specific bedroom and not the entire house. These models always work better in homes where there is not a forced air type of heating and cooling system. Whole house systems are the best for homes that feature an entire home forced air system for heating and cooling.

Factors to Base Decisions On

There are several factors that come into play when deciding on the right indoor air purifier to buy. These include the price range that is within ones budget, the ease of installing the indoor air purifier, the convenience of use and ease of cleaning air purifiers. Other factors include the noise level of an indoor air purifier and how much particles in the air each system is capable of removing from the air.

There are standards for indoor air purifiers based on industry and manufacturers ratings. They are not based on a health-related rating system, and it is important to remember this when choosing indoor air purifiers. Good ratings are 350 or higher. Ratings of below 100 are considered inferior.

Most Popular Air Purifier Brands

The most popular air purifiers for allergy use include Austin, Alen, Airpura, BlueAir, Honeywell, Airgle and Whirlpool. The highest rated air purifiers for asthma sufferers are selected as those made by Alen, AllerAir, Conway Macro, BlueAir, Airpura, Airgle and Austin.

The two most important things to think about when buying an indoor air purifier is taking both consumer and industry opinions into account. Another crucial issue is to make sure there is always a clean air filter in the air purifier. Having clean filters and purifiers in the home can help regulate both allergies as well as general health.

Central A/C, Humidity and Energy Efficiency: Buying Tips for Florida Residents

Posted on by

Residents of South Florida have a bigger challenge than people in many other areas of the country when it comes to the cost of cooling a home in summer. The very high levels of humidity combined with the high temperatures which occur in South Florida mean higher costs for running A/C systems in the region. While this is a fact which can not be changed, there are ways of improving the efficiency of a cooling system and some tips for operating Palm Beach air conditioners, which can help keep costs down as well as making the cooling system work more effectively.

An air conditioner works by removing moisture from the air as well as cooling the air. When there is more humidity in the air, the machine must work harder in eliminating that moisture. This means more electricity usage and higher power bills. An A/C being operated in a humid area like South Florida can easily take twice the power of the same system running in an arid environment. When the humidity of the cooled air is high, it does not feel as cool as air that is not humid.

A technology first patented in 1962 is helping with this problem and leading to cooler and more comfortable buildings in areas with high humidity. The technology is known as a heat pipes, or dehumidifying pipes, and it is a system that can be retrofitted to an existing heat pump or central air conditioning system, or installed as part of a new air conditioning unit that has the dehumidifying pipes built in.

Dehumidifying pipes are basically a pre-cooling system that treats the air before it reaches the evaporative coils of the central A/C system. It is a passive, closed system that does not require any power itself, but it does need an extra fan for circulating air over the dehumidifying pipes; however, the air cooled with dehumidifying pipes will feel better at a slightly higher temperature meaning that the thermostat can be set higher and the overall cost of running the unit will not increase.

A dehumidifying pipe consists of a pipe filled with a refrigerant with a low boiling temperature. As hot air moves past the pipe it transfers heat to the coolant which boils and rises. At the other end of the system the coolant reaches a condensing area and releases the heat to the outside. After this process the refrigerant then cools off and moves back down the pipe and the process starts over.

Moisture is also removed with the heat and the central air conditioning system then has less work to do in cooling the air. The air that is delivered to the rooms is cooler and less humid resulting in a more comfortable environment. A dehumidifying pipe can remove up to 91 percent more moisture from the air than a system without one.

Another way of getting more cooling efficiency out of an A/C system in a humid region is to run the system to pre-cool the house in the morning when outside temperatures are low. If the house is well insulated it will be able to retain this cool air as the day gets hotter and the A/C system can be kept at a lower temperature. By using this method your A/C may be turned off during the peak of the heat of the day so that you may save, as well as conserve on your energy and costs.

Newer air conditioning systems with higher SEER energy efficiency ratings cost less to operate. If a cooling system is old and has a low SEER rating, upgrading the system to one that also includes dehumidifying pipes might be the most economical solution for keeping the indoor environment cool, dry, and comfortable.

Tips for Buying Air Filters: Arrestance, Efficiency and HEPA

Posted on by

Whether it’s for your air conditioning unit, your air purifier or just your vacuum cleaner, choosing the right air filter is important to its performance. Most big-box hardware stores have shelf after shelf to suit practically every need and requirement, but the sheer amount of choice can be overwhelming. With so many air filters on the market to pick from, how do you know you’re getting the right one?

There are three key terms you need to be aware of during the selection process:

  1. Arrestance – How well a filter removes large particles such as dirt, hair, dust mites and lint from the air.
  2. Efficiency – How well a filter removes microscopic particles such as dust, pollen, mold, bacteria, and smoke from the air.
  3. HEPA – A high-efficiency particulate arrestance, or HEPA, filter conforms to the stringent guideline of removing 99.7 percent of particles – 0.3 microns or greater – from the air.

Almost all air filters are graded, listing a percentage of particles removed, using the above criteria.

Some other factors to consider when buying an air filter are:

What will the air filter be used for?

Not all air filters are created equally, and different devices and units have different requirements. HEPA filters can be found for a variety of machines, but are generally hard to come by for residential air conditioning units.

What size filter do you need?

One of the most common errors to make is not knowing the size of air filter you need before heading off to the hardware store. As helpful as the staff may be, it’s not something that should be estimated. A good trick is, once you’ve assessed the size you need, write it down either on the filter frame if available, the unit itself or as a note in your wallet so you have a go-to measurement at hand for next time.

What level of filtration do you require?

There are four rudimentary levels of filtration for most store-bought air filters:

  1. Basic – collects large particles like household dust, dust mites, lint, pet dander and pollen.
  2. Good – collects all Basic level particles plus bacteria and mold spores.
  3. Better – collects all Good level particles plus smoke, pollution, microscopic allergens and many virus-carriers.
  4. Best – collects all Best level particles plus odor-carrying particles.

*Most filters above Basic level are also electrostatically charged for optimal particle hold.

Will it need to be incinerated when you’re done with it?
The vast majority of air filters have the advantage of being either disposable or washable ones that you can reuse, but if you require a filter to separate out toxic or dangerous substances then it usually needs to be destroyed via incineration. In such a case, be sure to select a filter without metal components so it will burn easier.

Quick Reminders:

While UV light devices may claim to eliminate bacteria and certain particles, making your home healthier and cleaner, they can’t get rid of everything and are no substitute for a good quality air filter. Also, when choosing a new filter, remember that carbon is key if you want to remove odors and VOCs from your home. Keep in mind that a mere few ounces of carbon may not always do the trick, and that the best filtration units use much more.

Going Green: Window Film for Cost-Effective Energy Use

Regardless of where you live, chances are you’ve suffered a shock upon opening your energy bill at some point. Heating costs climb during winter while keeping cool can cost you dearly in summer, with a large part of these expenses being the fault of your windows. For instance, in summertime, 40 to 45 percent of your utility bill can be caused by solar energy that’s filtering in your windows. These UV rays aren’t just harmful to your skin, but to the rest of your home as well, prematurely fading carpets, wood flooring, drapes and furniture.

The addition of window film can offer a simple solution to you energy bill woes. At approximately $6 to $14 per square foot, it can provide a relatively inexpensive solution as well. There are two main types of window films on the market today: heat control and solar energy. Heat control films can block up to 55 percent of the sun’s heat from entering your home while solar films reflect up to 65 percent of solar energy. Titanium films are new to the market, blocking up to 72 percent of heat and can be found at big-brand home improvement stores.

Some benefits of using window film:

  • Better Indoor Temperatures
    In the summer, solar heat can filter through your windows and build up inside your home, making your air conditioning unit work harder to maintain a cool temperature. In contrast, wintertime can be just as harsh, with a large portion of heat being lost by butting up against cold window glass. Both of these instances can raise you energy bills while lowering your comfort level indoors. Using window films will keep your warm air from being lost during winter and your home easier to keep cool in the summer.
  • Glare Reduction
    Have you ever experienced a distracting window glare while applying makeup in the mirror or watching your favorite TV show? Not only can window film reduce the glare reflected off your windows while you’re outdoors, they help to reduce the blinding light that can filter indoors as well.
  • Privacy
    Make those nosy neighbors look somewhere else. With varieties ranging from frosted, tinted and even mirror finishes, window film can offer you a greater degree of privacy, reflecting the sun’s rays while keeping the outside world from peering in.
  • Protection
    Window film adds an extra layer of protection to the glass, preventing scratches and nicks over time as well as greatly reducing fading to your furniture and flooring. Also, if you live in a hurricane-prone area like the Gulf and Atlantic coasts, they can help lessen window breakage and the scattering of glass by bonding to the glass and making it more shatter-resistant. Many window films are even tough enough to help prevent larger storm debris from entering your home.
  • Decoration
    Even without window film’s benefits to your wallet and home interior, they can do wonders for decorating your home, such frosted films pairing well with bathroom windows.

As of 2011, folks were able to seek out federal tax credits – up to $500 – for using window films on their homes. However, the credit is only for the cost of the films, not labor or installation. For more information and other ways to make you home more cost-effective, visit EnergyStar.gov.

SEER Air Conditioner Efficiency Standards for Lower Electric Bills

Posted on by

A “seasonal energy efficiency rating,” also called a “SEER,” is a measure of an air conditioning system’s efficiency. By stating the average electricity consumption of an air conditioner during a typical “air conditioning season,” the SEER system allows consumers to more accurately estimate their energy usage than older rating systems allowed. A higher SEER indicates that an air conditioner uses less energy than those with a lower SEER.

For its calculation, a SEER assumes an air conditioner will be in use 1,000 hours per year, which represents eight hours of usage per day for 125 days during the course o/ds significant savings; upgrading from a SEER 9 system, which was previously a common rating, to a SEER 13 system will reduce electricity consumption by a bit over 30 percent. Upgrading from SEER 9 to SEER 16 will reduce energy consumption by nearly 45 percent. While exact savings depends on several variables, most homeowners will see an electricity bill reduction measured in hundreds of dollars per year.

To achieve a higher efficiency, manufacturers use thicker, more efficient metals in their air conditioners. Further, higher rated units generally have multiple compressors and larger coils. This raises the cost of the air conditioning system, so consumers must balance the cost of the unit with their expected energy savings. Most consumer guides recommend purchasing a system with a SEER of at least sixteen.

Additionally, air conditioning units degrade over time. An old unit which had a SEER of nine when it was first installed may currently be operating at a lower SEER. Air conditioning units today tend to retain their rating longer, but it is worth noting that the more expensive materials used in more efficient systems can be expected to help maintain the unit’s rating longer than less efficient systems.

And for those who seek to reduce their impact on the environment, a system with a higher efficiency rating helps reduce energy-related pollution. Systems with a higher SEER will also last longer and reduce the amount of material that ends up in a landfill.

At one time, those looking to purchase a new air conditioner had no means to calculate the energy cost of their purchase; manufacturers had no incentive to focus on efficiency over cost. The SEER system has provided consumers with a valuable tool to calculate the true cost of their new air conditioner.

Air Conditioning: Keeping Cool for 110 Years and Counting

Life Before Home Air Conditioning

As the temperatures climb higher outdoors, folks everywhere are seeking refuge indoors thanks to their beloved air conditioning systems. However, so many of us have come to view what was once a luxury as a necessity for daily living. Many more have forgotten about air conditioning’s humble beginnings, and the man who literally redefined what it meant to “be cool” back in 1902.

The summer of 1902 was another record-breaking scorcher all over the Eastern seaboard, but New Yorkers were hardest hit. Handfuls of citizens were falling ill each week due to heat stroke and dehydration. To be working indoors during this time, with industrial machinery cranking out even more heat inside buildings with little ventilation, was practically unbearable and even a death sentence for some. The week prior to July 17, 1902, seven people died from heat-related issues.

Air Conditioning Pioneer, Willis CarrierOn the second floor of a Brooklyn publishing building, the Consolidated Lithographing Corporation was busy creating the next issue of the humor magazine, Judge. The magazine featured whimsical images which had to be printed color by color, for instance, black one day and cyan the next and so on.

However, the heat and built-up humidity meant the ink wasn’t drying fast enough and the colors weren’t lining up properly. Also, the paper began to curl at the edges, making it difficult to feed into the printing press. Production would suffer from frequent delays because of these complications.

Enter Willis H. Carrier, a young engineer fresh from Cornell University and employee at Buffalo Forge Furnace Company who developed a solution to the company’s cooling problems: air conditioning.

While a far cry from the central air systems we know today, Carrier created the necessary foundation. He revolutionized a way to cool down workers and their heat-building machines by blowing air over cold water pumped from underground springs into the building. Production no longer had to suffer, and the concept of controlling temperature snowballed. Called “a Johnny Icicle planting the seeds of climate control all across America” by American Heritage Magazine, Willis H. Carrier had started a movement that took the world by storm and redefined the standards of home living.

History of Central Air Conditioning

  • 1903 – Carrier built a refrigeration unit to cool the water pipes faster.
  • 1911 – He released the Rational Psychometric Formulae, which became known as the “Magna Carta of Psychometrics” and the building blocks for modern air conditioning.
  • 1925 – The modern air conditioning system, featuring air blown through water instead frost-prone pipes, debuted at Broadway’s Rivoli Theatre.
  • 1955 – One in every 22 American homes had air conditioning.
  • 1960 – One in every five American homes now had air conditioning.
  • 2003 – During another sweltering summer, a blackout across the Northeastern U. S. reminds people how intolerable modern life would be without Carrier’s invention.
  • 2010 – Over 100 million American homes, 87 percent of the population, have air conditioning.
  • 2012 – The Brooklyn publishing building, where it all began 110 years ago, still remains without central air. Window units dot along the second floor of what is now rented studio space.

Many have even said that Willis Carrier paved the way for the Internet, since his air conditioning unit reduced dust and allowed for the construction of clean-rooms in computer and electronic companies. No one can argue that Carrier changed the nation, even the world, with his miraculous invention, yet scientists and ecologists are concerned that our dependency for air conditioning is unsustainable in the long run. Many countries like China and India burn coal in order to supply energy to their electricity grids, which includes air conditioning their homes and businesses, and this means a hotter planet overall for Carrier’s creation to attempt to cool down.

Despite worries about the future of climate control capabilities, the present has given us a respite from the summer heat all thanks to Willis Carrier and his brainchild. Happy birthday, air conditioning, and thanks for still being so cool after 110 years.

Is Your Electrician Really Qualified For The Job?

qualified electricianThe electrical system is clearly the brains inside the house. It controls almost all of the activities and allows you to smoothly perform your daily functions.

The system, however, is also one of the most critical aspects of the house especially when it comes to safety. A faulty wiring can risk your life and turn your invested property into ashes in a matter of minutes.

Be it the installation of new electrical lines or a rewiring job, it is imperative that you seek the services of a licensed electrician and stop considering doing it yourself or hiring an unlicensed contractor.

In the current job market, a lot of contractors identify themselves as electricians, although only a few of them actually possess a license. It can be quite tempting to take on their offer, as they are far more inexpensive when compared to the fee of a professional electrician. However, if you want to ensure that the safety of your property and the lives of your loved ones are not compromised, then it would be better to shed some dough and contact a reliable, licensed electrician.

Benefits of a Licensed Electrician

One of the main reasons as to why a licensed electrician is the most reliable choice is the fact that this person has a clear understanding of the building code and the guidelines set by the NEC. This means that he will not second-guess on his methods and scrimp on the quality of the materials that he will use in performing the job.

Acquiring a license entails experience, training and an above-average understanding of the electrical system, and these requisites are all present in a professional electrician. With a licensed electrician, you can expect quick, accurate and quality service and they can also provide you with a guarantee of their work.

qualified electricianSince licensed electricians are familiar with the legalities concerning electrical works, they can also help you in these aspects.

Prior to starting out an electrical work such as a major rewiring or installation, you will need to secure an electrical permit in order to avoid being reprimanded by the authorities and fined with a large sum of money. A licensed electrician can facilitate and get you the necessary electrical permits needed so that they can start working as soon as possible.

Insurance Verification Benefits

If you are homeowner who lives in an old house and you are considering applying for an insurance policy or selling it, a licensed electrician will also prove to be very beneficial for you. Most insurance companies and real estate agents will ask you to verify that the electrical wiring in your house is in good condition and complies with the specification of the current building code. Your licensed electrician can perform the rewiring, repairs or the inspection for your residence and issue a “test and inspect” certification which bears the report that your house is not a potential fire hazard.

Hire a Licensed Electrician

Upfront, the service cost of a non-licensed electrical contractor is undeniably lower than what the licensed electrician will quote you. Keep in mind, though that these people are not sufficiently trained, cannot give you any kind of permit or certification, and they are susceptible to leave the work incomplete. When you look at it closely, a licensed electrician will be far more cost-efficient and they can help you avoid future complications, be it from faulty wiring or from legal and technical issues.

Post-Recession Shift in Home-Buying Market

Lang Realty Releases Palm Beach County Real Estate Update

post-recession real estate recoveryThe housing market has faced serious difficulties since the wake of the recession, but it seems that the storm has finally begun to clear. And if there’s anything to be learned from nature, its that destruction breeds creation, and the cycle of life begins anew.

What does this mean for a prospective home buyer? The post-recession recovery is leading to a boom, in which buying up foreclosed properties has become a valuable investment opportunity.

Today’s home buyers in Palm Beach County are seeing inventory tightening up and demand becoming higher. “For six years we have seen no new building in our area and essentially the demand caught up. Any foreclosures are being scooped by investors and there is more demand than supply” remarks Lang Realty President, Scott Agran.

Lang Realty is a local South Florida real estate based in Palm Beach county that monitors real-time real estate market data and home pricing and selling trends.

With inventory shrinking, the early adapters which represent 20 to 25% of the market understand now is a time to buy a home. The fact that mortgage rates are at their lowest in years is also helping to fuel this upward trend among this group. State data shows that Palm Beach County’s median sales price for an existing single-family home lifted to $197,000 in March, a 6 percent increase from February driven in part by depleted inventory and voracious investors.

Benefits of Home Investing in Today’s Market

buying a houseUnlike buyers of the last few decades, today’s new homeowner does not have to succumb to purchasing a property during an age of dwindling property values.

The buyer’s market is now significantly more optimistic then it has been in years. Appraisals match the decided upon purchase rate and interest rates for mortgages are affordably low. Even existing homeowners currently bogged down by a pre-existing mortgage now have the opportunity to sell without having to accept a loss.

The struggling homeowners who managed to bear through the worst and hold off on foreclosure or a short sale during the peak of the recession, now is the best opportunity to sell their current place and free themselves of “unsustainable mortgage obligations.”
