The Differences Between Air Filters and Air Purifiers

February 25th, 2014

Air filtration can do a great deal to keep the spores and allergens of our humid climate in check, as well as making your Lake City, FL home a more pleasant place to be in general. Air filters and air purifiers are both connected to your home HVAC system, and both concern themselves with the quality of your indoor air. Beyond their basic function, however, they’re very different pieces of equipment. Which one you use – and the reasons why – tie into the specific circumstances of your home. Here’s a brief rundown of the differences between air filters and air purifiers.

For starters, a certain type of air filter is a completely necessary part of your existing HVAC system. You could technically run it without them, but you certainly wouldn’t want to. Air passes through the filter when your system runs, trapping dust, dirt and other particles in the process. This helps keep the system clean and prevent dust from building up on its components. These air filters are designed to be replaced after a few months (though some of them are washable and can be reused after they are clean). You can also add additional mechanical air filters to your HVAC system to improve your air quality. These come in different MERV (minimum efficiency reporting value) ratings depending on the size of particles you want removed, and trap the particles as the air in your ducts passes through them.

Air purifiers, on the other hand, are a little different. These are usually electrically powered and are designed to collect particles differently. Instead of trapping dust and debris in the filter, they use a charged ionization chamber to give pollutants an electrical charge, then the particles accumulate on collector plates with the opposite charge. Purifiers are not a standard part of most HVAC systems, but they can be installed in most existing systems as a way of further purifying your air.

The two are basically different levels of treating the same problem. You’ll always need at least one air filter, but if you want to augment it with the installation of an air purifier, that’s up to you.

3 Upgrades That Can Improve Indoor Air Quality

February 17th, 2014

According to the U.S. Environmental Protection Agency, low indoor air quality is one of the major threats to health in the country today. Because modern homes are sealed to keep out heat in the summer and trap it during the winter, there is less proper ventilation of fresh outside air. Although it’s easy to open up the windows to allows in the air, that ceases to be an option when the weather becomes too warm or too cold.

There are upgrades to your home’s ventilation system that will help you improve your indoor air quality in Lake City, FL. Touchstone Heating and Air Inc. can assist you with finding which of these upgrades will benefit you.

3 upgrades we recommend for indoor air quality

UV germicidal lights: People do not like to consider the possibility of mold and other bacteria developing inside their ductwork. However, this is a frequent problem in humid Florida weather, and it needs to be dealt with because of the negative effects it can have on your air. The best way to safely remove microbacteria from your ventilation system without using sanitizers or sprays is with UV germicidal lights. The high-frequency rays from these fixtures destroy the cellular structure of bacteria and prevent them from returning—all without damaging your ducts or your air.
Air filters: Mechanical air filters, which trap contaminants in a dense bed of fibers, are a simple but very effective ways to keep your indoor air clean. The effectiveness of a filter is measured as MERV (minimum efficiency reporting value), with a higher number meaning greater efficiency at trapping contaminants. Air filters must be properly matched to an HVAC system; for this you should rely on professional installers.
Air purifiers: These devices go a step beyond the mechanical air filter and use electrical power to take an active approach to cleaning the air. These purifiers ionize particles in the air and attract them to collector plates. This method allows the air purifier to trap particles far smaller than what a standard mechanical filter can.

Find out what indoor air quality upgrades you need

Not every home needs the same air quality issues addressed, and any upgrades will need to be matched to your HVAC system. You should contact indoor air quality specialists to help you find the solutions you need to improve the air you breathe in your home every day.

Touchstone Heating and Air Inc. is serious about helping you have better indoor air quality in Lake City, FL. We can install a variety of filters and purifiers, as well as UV germicidal lights. Contact us today to find out what we can do to help your home health and comfort.

Who Wrote the First Valentine’s Day Poem?

February 14th, 2014

The celebration of Valentine’s Day is often seen as a modern institution, even if the roots of the holiday go back to Late Antiquity and the figures of St. Valentine of Rome and St. Valentine of Terni. It’s difficult to separate our view of February 14th from the more recent phenomenon of greeting cards, comical cupids, and specialty treats from candy companies.

However, not only are some of these traditions older than we might think (mass-produced Valentine’s Day cards were an enormous success in early 19th-century England), but the earliest Valentine’s Day love poem comes from none other than the first great English author, Geoffrey Chaucer, who wrote in the second half of the 14th-century.

Chaucer’s most famous work is The Canterbury Tales, an enormous collection of linked stories in poetry and prose. But his 700-line poem “Parlement of Foules” has the special distinction of being the first surviving record of a connection between Valentine’s Day and romantic love. Chaucer probably composed the poem in 1381–82. At the time, he was a member of the court of King Richard II, holding an important bureaucratic position in London. The date suggests that Chaucer wrote “Parelment of Foules” to honor the first anniversary of the engagement of the English king to Princess Anne of Bohemia.

The poem follows the dream of the narrator, where he walks through Venus’s temple and discovers a meeting of birds where they all choose their mates. This is where the mention of St. Valentine’s Day appears (English modernized):

For this was on St. Valentine’s Day,

When every bird cometh there to choose his mate.

The poem also contains a familiar Valentine’s image, Cupid with his arrows:

Under a tree, beside a well, I saw

Cupid our lord his arrows forge and file;

And at his feet his bow already lay.

When Chaucer mentions St. Valentine’s Day, is he referring specifically to February 14th? Late winter isn’t a time when birds in England would mate. However, the date for the start of spring—when some birds would have started nesting in England—was on February 23rd in the calendars of the time, certainly close enough for Chaucer to take poetic license and nudge it a bit to match with Valentine’s Day.

Love birds remain a popular symbol of Valentine’s Day even now, and for this we can thank Chaucer. In fact, he may very well have invented the link between love and Valentine’s Day, although we will probably never know for certain.

Whoever started these traditions, all of us here at Touchstone Heating and Air Inc. hope you have a wonderful February 14^th!

Why Heat Pumps Are Popular for Heating

February 6th, 2014

Many homes in our area use heat pumps to keep comfortable throughout the winter. The technology uses a refrigerant cycle similar to that seen in air conditioners to both cool and warm the house. During the summer, the heat pump absorbs the heat from your house and transfers it outside, and during the winter it absorbs heat from the air outside and brings it in. It’s an effective system, which is just one reason why heat pumps are popular for heating in Gainesville, FL. A short list of additional reasons can be found below.

Energy efficient. Heat pumps don’t actually create heat. They simply transfer it from the refrigerant to the surrounding air. The process is very efficient, which means that heat pumps use less energy than other types of heating.
Warm-weather friendly. Heat pumps lose their efficiency when the weather drops below 40 degrees Fahrenheit, though most are equipped with electric resistance coils that can turn on for very cold days. Luckily, Florida weather only rarely dips down that far, making heat pumps a good fit for our balmy climate. Since they provide excellent air conditioning, you can take care of your year round comfort with just one system.
Cost savings: Since you only need a single heat pump for both heating and cooling, you can have a lower installation cost than installing a furnace and a central air conditioner separately.

Understanding why heat pumps are popular for heating in Gainesville, FL is just part of the equation. The other part comes with finding a reliance service to maintain and repair your heat pump. For issues with heating in Gainesville, FL, the experts at Touchstone Heating & Air Inc. are ready to help. Give us a call when your heat pump experiences problems, or you just need a little maintenance to keep it running at its peak!

Signs of a Heat Pump Refrigerant Leak

January 29th, 2014

Did you know that heat pumps operate according to the same principles that air conditioners do? They circulate refrigerant and take advantage of the temperature changes created when it shifts from a gaseous to a liquid state and back. When refrigerant leaks out of the system, it can cause problems with your heat pump, just like it can with your air conditioning system, that need to be corrected immediately.

Here are some ready signs of a heat pump refrigerant leak:

The biggest sign of a refrigerant leak is the formation of ice on the evaporator coils (either indoor or outdoor, depending on your heat pump’s current mode). Like air conditioning units, heat pumps need specific levels of refrigerant to work. When those levels drop, the cooling or heating process is compromised and ice forms, not only preventing your heat pump from working efficiently, but also insulating the remaining refrigerant from absorbing heat.

A more direct sign comes with your heat pump’s reduced ability to heat or cool the air. You may notice this simply by feeling the air being blown into your home, or in the fact that the heat pump runs longer than it usually does during the cooling or heating process. You might also notice it in your monthly bills, which go up dramatically despite the fact that you’re not running the heat pump any more often than normal.

Tracking down the leak can be difficult, since the refrigerant usually escapes in gas form and doesn’t betray any overt signs of removal. Trained technicians can detect the leak using specific equipment, then seal it up and recharge refrigerant levels to restore functionality to your system.

Heat pumps are very popular here in Florida, in part because they work best in places with mild winters like ours. If you live in Gainesville FL, heating repair companies like Touchstone Heating and Air Inc. can help you with refrigerant leaks. Once you spot signs of a heat pump refrigerant leak, give us a call to repair the damage. We have the experience to do the job right, and our technicians are dedicated to your complete satisfaction!

Are Unusual Noises a Good Reason To Call For Furnace Repair?

January 22nd, 2014

If you have a forced-air furnace, you’re used to it making noise when it turns on. The blower fan has a motor that makes some noise, and there is also the noise of the warm air circulating throughout your house. But what happens when those noises don’t sound normal? Are unusual noises a good reason to call for furnace repair? Usually, the answer is yes. If you need Gainesville FL furnace repair services, call Call Touchstone Heating and Air Inc.

An unusual noise invariably suggests a problem that needs fixing, though the precise nature of the problem varies. The noise itself may provide a few clues. A rattling sound likely indicates something loose within the furnace, while a buzzing or humming suggests some kind of electrical problem. If the fan motor or some similar component runs into trouble, it’s apt to emit some kind of buzzing or grinding noise. Sputtering burners might also make unusual sounds and if the fan blades themselves are bent, they will make grinding noises as they rub up against their casing.

Whatever the exact sound, if you detect it, it means trouble. Ignoring it and hoping it will go away is probably the worst thing you can do in this situation, since the problem causing the noise will likely get worse until your heater breaks down completely. Instead, take careful note of when the noise first arose – At the start of the heating cycle? When it shuts down? Have whatever information you can get ready for when you furnace technician arrives.

Call the experts at Touchstone Heating and Air Inc. to pinpoint the problem and make repairs. We are available 24/7 for Gainesville, FL, furnace repair services.

Leaking Refrigerant and Heat Pump Repair

January 14th, 2014

Heat pumps use refrigerant to absorb heat from the air, which is either transferred to the inside or outside of your home, depending upon whether its in heating or cooling mode. That allows the heat pump to warm your home in the winter when temperatures are low and cool it in the summer when things get hot and muggy. All of that depends on the right amount of refrigerant, however. When it leaks, it can cause some significant problems. Here’s a basic rundown on leaking refrigerant and heat pump repair.

Refrigerant can leak out of the system at any point, but often seep out from a breached line or an imperfect fitting between two components. It’s often undetectable to the naked eye, though trained service professionals have tools to accurately pinpoint the source of the leak. In any case, the breach invariably lowers the amount of refrigerant in the system, which depends on a very specific amount of gas to work.

The cooling process takes place in the evaporator coils, which receives a set amount of liquid refrigerant from the expansion valve. Once it enters the coils the liquid evaporates, drawing heat from the surrounding air in the process. If the refrigerant levels are too low, the pressure will be too low, and you can wind up with frozen coils that won’t be able to absorb heat from the air.

Repairing the issue means hunting down the source of the leak and sealing it before recharging refrigerant levels to their recommended levels. The experts at Touchstone Heating & Air can help. If you need heat pump repair in Gainesville, FL, give us a call!

Why a Portable Generator Will Not Do the Job

January 6th, 2014

Here in Lake City, FL, a generator is a great addition to any home. Hurricanes are a regular fact of life here, and while our civic electrical system does a great job, occasionally losing power is to be expected. A generator means keeping food cold and comfort levels high, as well as maintaining contact with the outside world through radio, television and the internet. Some residents opt to use portable generators for such circumstances, which allow them to take the generator with them when they move. This can be a mistake. Here’s a list of reasons why a portable generator in Lake City will not do the job.

Size. Portable generators are usually very small, which will do in pinch but will struggle to meet your power needs for an entire household. A permanent generator, on the other hand, can be properly sized to meet the needs of your entire household, ensuring that you always have power when you need it.
Hazards. Portable generators can create toxic gases such as carbon monoxide, which can be a health hazard if the generator is run inside. Every time you use your generator, its imperative that you ensure it is vented properly. A permanent generator, on the other hand, will have its own venting system set up when it is installed, keeping you and your family safe while still providing reliable power.
Resale value. If you move away from hurricane country, chances are your need for a generator will diminish significantly, eliminating one of the big benefits of a portable model. A permanent model, on the other hand, will improve the resale value of your house, helping to cover the costs of installation.

For more on why a whole house generator is better than a portable one, contact the experts at Touchstone Heating & Air, Inc. We handle Lake City, FL generator issues of all varieties, and will install a permanent generator in your home that will make those hurricanes much easier to endure. We’re standing by to take your call, so don’t hesitate!

The Ball in Times Square

December 30th, 2013

New Year’s is a time for parties, fun and great traditions, some of which go back more than a century. Among them is the famous “dropping of the ball” in Times Square, an event which is broadcast to millions of people every New Year’s Eve. With 2014 nearly upon us, we thought we’d take the opportunity to look at the history of this popular New Year’s Eve festivity.

The idea began in 1907 at what was then the New York Times building at One Times Square. The newspaper’s owner, Adolph Ochs, had been celebrating the New Year with fireworks since 1903. He wanted make the event even more remarkable, and added the ball in December of 1907 to welcome in the New Year. The first ball was designed by Artkraft Strauss, who made it out of iron, wood, and light bulbs. It took six men to hoist the ball up the building’s flag pole; once midnight struck, the tremendous ball was carefully lowered, and all were allowed to marvel at it.

Since then, the ball has undergone many changes in materials and design, and even the New York Times has moved to another building. But the tradition remains and the ball has dropped over One Times Square ever since. Today, the ball is electronically controlled, and uses LED lamps for its construction: designed by Waterford Crystal and weighing in at over 1,200 pounds.

A number of television broadcasts have helped carry the event over the years, but by far the most famous is “New Year’s Rockin’ Eve,” which first ran in 1972. The show was created and hosted by Dick Clark, who became a staple of the event as much as the ball itself. Clark hosted the show every New Year’s Eve from 1972 until his death in 2012. Since then, it has been hosted by Ryan Seacrest, who shared hosting duties with Clark starting in 2005.

Whether you’re watching the ball drop on TV or have some other New Year’s Eve plan in mind, we here at Touchstone Heating & Air wish you nothing but the best for 2014. Have a safe and happy New Year!

Happy Holidays!

December 23rd, 2013

Holiday greetings from Touchstone Heating & Air! We hope you are having safe and pleasant season, enjoying your favorite traditions for this time of year. We wish you the very best, and we thank you for your business this year.

In honor of the season, here are some fun facts about one of everyone’s favorite holiday movies: It’s a Wonderful Life.

For years, one of the enduring December traditions in the United States was watching the movie It’s a Wonderful Life playing almost nonstop on numerous television stations. No matter the time of the day, you could turn on the TV set, flip through channels, and discover It’s a Wonderful Life playing. Whenever you needed him, you could find Jimmy Stewart shouting, “Hello, Bedford Falls!”

But now… It’s a Wonderful Life only appears on broadcast television a few times during December, and most families instead choose to watch the movie on video. What happened?

The reason goes back to the film’s initial wide release in January 1947. (That’s right, it opened after the holiday season. It was not even promoted as a holiday film.) It’s a Wonderful Life was a box-office disappointment at the time, and its studio, RKO Radio Pictures, lost more than half a million on it. The movie’s production company, Liberty Films, was sold to Paramount to avoid bank foreclosure. (A bit ironic, considering the movie’s plot.) In 1955, the National Telefilm Associates (NTA) took over the rights to It’s a Wonderful Life, which included the television syndication rights.

However, NTA failed to properly renew the copyright in 1974 because of a clerical error, which allowed the film’s images to enter into the public domain. Although the movie’s plot was still under copyright protection because it was adapted from a published story called “The Greatest Gift,” television stations across the world could now broadcast it with only minimal royalty payments.

In 1993, Republic Pictures, which now owned the NTA library, tried to enforce their claim to the copyright of the film, as they possessed the rights to “The Greatest Gift.” Republic Pictures succeeded, and licensed exclusive television rights to NBC. Suddenly, It’s a Wonderful Life vanished from local television stations, and NBC made the movie’s broadcasts—usually twice during December—into major events. As of 1998, Paramount again has the rights to It’s a Wonderful Life… 43 years after they lost them.

It’s still easy to make It’s a Wonderful Life a part of whatever traditions you observe during the holidays, whether through home video or television broadcasts. Despite its lackluster initial reception in 1947, Frank Capra’s film is now an inseparable part of December in the United States.

Have a great holiday week!
