Your Athens AC System and Your Energy Recovery Ventilator

Monday, March 26th, 2012

As an Athens homeowner with an air conditioning system, you know that it costs plenty to keep your home cool and comfortable in the summer. It is an expense you are willing to pay for the comfort and overall health of your family, but if you are like most homeowners, you would do anything to lower your monthly electric bills where possible.

One way to make your air conditioning system a little more efficient is to install an energy recovery ventilator. Read on to learn what energy recovery ventilator is and how it works alongside your Athens AC system to reduce energy loss and improve indoor comfort control.

What is an energy recovery ventilator?

Not to be confused with a heat recovery ventilator, an energy recovery ventilator is a mechanical device that transfers heat and water vapor between the incoming (i.e. outside) air and outgoing air being moved by your ventilation system.

The main difference between an energy recovery ventilator and a heat recovery ventilator is that the former transfers both heat and moisture, while the latter transfers only heat.

 What does an energy recovery ventilator do?

What does that transfer mean for your air conditioning system? Well, in the hot summer months, your air conditioner pulls in warm air from the outside, cools it and then blasts it into your home, while exhausting warm air to the outside.

What an energy recovery ventilator does is make that process a little easier for the air conditioner to handle by transferring heat from the warm air coming in to the exhaust air that the AC is blowing out of the house. The incoming air therefore has to be cooled less, which means your AC doesn’t have to work as hard, which means less electricity is used.

Many users of energy recovery ventilator systems report that the moisture exchange also makes the air in their homes feel “fresher,” rather than the stale feel that air conditioning can sometimes produce.

So, if you would like to increase efficiency and reduce the cost of running your Athens air conditioning system, consider an energy recovery ventilator as one possible solution.

Tucker Indoor Air Quality Tips: Improving Indoor Air Quality with UV Germicidal Lights?

Wednesday, March 14th, 2012

Ultraviolet germicidal lights improve indoor air quality in your Tucker home by killing the harmful bacteria, viruses, and toxic mold that can cause respiratory problems and other health concerns. These microorganisms spread by releasing airborne spores containing the genetic material used to create a new organism. UV lights use a wavelength of ultraviolet light to destroy the organism’s DNA, which takes away their reproductive capabilities and also kills them.

UV germicidal lights are fairly inexpensive and can be installed to work with your Tucker forced air HVAC system. They are typically used in tandem with either an electronic or mechanical air cleaner. While air cleaners can filter pollen and other irritants, UV germicidal lights destroy the viruses and mold spores once these pollutants have been trapped by the air cleaner. After the air has been filtered through your HVAC, it will circulate more easily through system and increase the efficiency of the unit. In addition, UV lights are useful in killing hidden mold growth, which can only be detected by special thermal imaging equipment.

Homeowners with particularly chronic allergy problems or extremely poor indoor air quality choose to install both types of air cleaners, in addition to a UV light, for the ultimate protection from indoor air pollutants—from bacteria to pet dander.  If your home lacks adequate ventilation, or if you are unable to control the source of common pollutants, you might benefit greatly by installing UV germicidal lights. Poor indoor air circulation can exacerbate the spread of harmful microorganisms, so make sure you have proper ventilation if you don’t have UV lights in your home.

UV germicidal lights have also been used to filter tap water because they are more reliable and easier to install than other water treatment systems. However, they are typically used to provide cleaner indoor air.

Call the indoor air quality experts at Triad Mechanical if you have questions or concerns about the quality of the air inside your Tucker home.

Lawrenceville Indoor Air Quality Question: What Type of Air Cleaner Is Best for People with Pets?

Wednesday, February 8th, 2012

Lots of people in Lawrenceville have pets, and they are a great addition to your family. However, pet ownership has one very obvious drawback: dander. The fur, dry skin cells and other debris that pets carry around flakes off their bodies and onto your furniture and rugs. The also means they inevitably wind up in your air, recirculated through your whole house via your HVAC system.

Or at least, that’s what happens if you don’t have an air cleaner or some sort of air filtration system. This leads many pet owners to ask, “what is the best air cleaner for me?”

With all the choices in air cleaners, the choice can seem daunting. If the goal is specifically to filter out pet dander, it becomes somewhat easier.

Pet dander is quite large in size relation to other indoor air pollutants, so many air cleaners are equipped to do the job. You can use an air cleaner with a standard pleated HEPA filter, or one that uses electrostatic technology. You will want to make sure that the HEPA filter is rated to handle pet dander. A MERV rating of 8 or more is recommended.

Once you have an air cleaner installed, make sure to change or clean the air filter frequently, in accordance with manufacturer instructions. A clogged air filter won’t help eliminate pet dander from your household air and can actually degrade the operation of your HVAC system’s air handler.

In addition to installing a high quality air cleaner with a HEPA filter, you can also help reduce the amount of pet dander floating around your home by keeping the place clean. Vacuuming often and dusting hard surfaces weekly keeps pet hair and dander from being drawn up into the HVAC system, which reduces wear on the air cleaner. If you need any help choosing the right air filter for your home, call Triad Mechanical!

Stone Mountain HVAC Tip: Seasonal Air Quality Control

Monday, January 23rd, 2012

For people who suffer from seasonal allergies in Stone Mountain, air quality is a key concern. Allergens in the air cause brutal bouts of sneezing, runny nose, itchy eyes and even sinus headaches. Even taking refuge indoors will often not assuage these symptoms, as indoor air is often comparable to outdoor air in terms of allergens and overall quality.

That is, unless you take care to control the seasonal air quality in your home, which can not only help ease the suffering of allergies, but also soothe asthmatics, keep out pollutants and generally promote better overall health.

How do you go about controlling the air quality in your home? To start, try these simple tips:

  1. Vacuum carpets regularly. Use a vacuum with a HEPA filter and invest in some allergen suppressing bags.
  2. Keep your vents clean. This is also a good maintenance practice to lengthen the life of your ventilation equipment.
  3. Dust hard surfaces and wash bed linens weekly.
  4. Install HEPA filters in your ventilation system, such as in air conditioners or other air handler units. Use a higher rated filter to keep out more allergens and pollutants.
  5. Invest in and use an air purifier. Again, make sure to get one with a HEPA filter.
  6. Have your home tested for radon and carbon monoxide. Have smoke, carbon monoxide and radon detectors working properly at all times.
  7. Use a humidifier to keep overly dry air from irritating sinus passages.
  8. Keep doors and windows closed tight, especially during allergy season(s).

By taking charge of the air quality in your home, you also take control of a measure of your family’s health. Some of these measures require at least a bit of an investment – for example, higher rated HEPA air filters are often more expensive and need to be changed more frequently – but the benefits to your well being and that of your family are clearly well worth it.

What is Air Purification? A Question from Winder

Friday, November 4th, 2011

The air around us, in Winder and everywhere else, is getting more and more polluted these days, and people are trying to do more and more to combat it. Cars come with ratings like “ultra-low emission vehicle” and windmills generate power from moving air rather than burning coal. No doubt, these efforts help, but if you want to take an active role in improving the quality of air in your own home, consider an air purification system.

Simply put, air purification is the process of removing contaminants and pollutants from the air. There are a number of devices on the market that can purify the air in your home. While anyone can enjoy the benefits of cleaner air, they are of particular utility for people which suffer from asthma or allergies, or who live in areas with higher concentrations of outdoor air pollution.

There are three main kinds of air purifiers, categorized by the kind of technology they use:

  1. HEPA filtration
  2. Negative ion generation
  3. Electrostatic precipitation

HEPA filtration purifiers simply filter the air that passes through them using a sieve-like filter or series of filters. Depending on the efficiency of the device and the filter, some of these purifiers can trap not only solid and like particles, but also gases and odors. One advantage of this type of purifier is that the HEPA filters can last for years before they need to be changed.

Negative ion generation and electrostatic precipitation models are more complicated and technical because of the technology they use. Consult with a professional to choose which kind of technology is best for your needs, depending on the air quality problem you are experiencing. Some air purifiers can trap bacteria, viruses, fungi or chemicals, so there is bound to be one that will suit your needs.

After deciding on which type of technology you need, you will also have to choose whether you want a portable air purifier unit or a central system that covers the whole house. Obviously the former works well if you are only concerned about the air in a room or two, while the latter is better if you have chronic asthma or a more widespread air quality problem.

How Often Should I Replace My Furnace or Air Conditioner Filter? A Question From Hoschton

Wednesday, September 14th, 2011

Just like the filter in your air conditioner, replacing your furnace filter is the key to a healthy and comfortable Hoschton home. By keeping a good filter replacement schedule, you will reduce wear and tear to the furnace or air conditioner and keep your home comfortable, while keeping your family healthy and controlling energy costs all year.

But when does your furnace or AC filter need to be changed? Well, each system is different, but there are some general guidelines and recommendations to follow that can help you keep it all straight and stay on top of your furnace filter situation.

Conventional Wisdom

The long-standing rule of thumb on furnace filters is to change them every month. This is good practice if you are using older fiberglass filters, but for newer, more efficient filters, you should do it a little differently. These should be inspected and cleaned at least once a month, but you may need to replace them that frequently also. AC filters need to be changed every three months.

Sometimes it is a little more complicated than these general guidelines, so it pays to be aware of some factors and conditions in your home that may affect how frequently you need to change your filter.

Things to Consider

As mentioned above, the first thing to consider is the efficiency of the filter. Because new filters are so efficient, when they get dirty or clogged with dust and debris, they actually restrict airflow, making your furnace bog down and work harder. So, it is important to stay on top of a monthly inspection and cleaning schedule with these filters.

Also take into account air quality and sources of allergens both inside and outside your home. If you live in an area with a lot of pollutants in the air, you’ll want to replace your filters often to keep those out of your home. If you own a lot of pets, the dander and hair will wind up in your furnace filter and you may have to replace it more often.

Complicated enough for you? It doesn’t have to be. Simplify the whole process by doing the following: check your filter monthly and be prepared to change it that often, clean high-efficiency filters regularly, replace the filter at least every three months and again at the start of heating season.

If you do those things at a minimum, you will be in pretty good shape.

Common Types of Air Cleaning Devices: A Tip From Athens

Monday, September 12th, 2011

In recent years in Athens, you’ve likely heard dozens of warnings from newscasters, community publications and local contractors about the dangers of indoor pollutants. That’s a good thing – the air in your home, if left untreated, can be a significant health risk to you and your family. But, how do you choose an air cleaner that will get the job done? Let’s take a closer look at the options currently available and what each of them has to offer.

Air Filters

Air filters are the simplest form of air cleaning. They are designed to capture particles that stay airborne long enough to reach the filter. They don’t work well to capture all large particles, however, because they tend to settle before they reach the filter device. Proper air flow is necessary to supplement the process and remove more pollutants.

High efficiency filters with an MERV rating of 14 or higher are recommended, though HEPA filters (which have an MERV of 17-20) are preferred for their ability to capture particles as small as 0.3 microns. In-duct particle removal is a good upgrade as well because it filters moving air and captures more particles.

UVGI

UV germicidal lights are designed to kill pollutants like bacteria and mold. They are usually installed in the ductwork or air cleaner and while the effectiveness of either has yet to be properly measured there is a growing trend to include them in systems where homes experience a large number of allergic reactions or asthma symptoms.

Ozone Generators

There are still some systems that produce ozone as they circulate air back and attract it to a filter for removal. The results are mixed and ozone itself can be a significant irritant to the lungs, so it’s unclear whether these actually work very well (we would not recommend them).

Which Is Best?

It really depends on the pollutants you’re trying to remove. The best course of action is to discuss with a contractor the best combination of technologies to remove pollutants from your indoor air.

5 Ways to Improve IAQ and Reduce Air Pollution: Some Tips From Commerce

Friday, September 9th, 2011

Your Commerce home could be a haven for pollutants that can cause irritation to the upper respiratory system of anyone who comes inside. These allergens and pollutants are easy to remove however by taking some simple steps such as the five listed below:

  1. HEPA Filtration – Step one is to use HEPA filtration to remove as much of what is on the floor as possible through vacuuming. HEPA vacuum cleaners can remove years of cleaners, solvents, dander, mineral build ups and other toxins that tend to accumulate in spaces that normal vacuums cannot reach. It may be a bit of an investment, but a high powered vacuum cleaner can have a tremendously positive impact on your lifestyle and reduce pollutants.
  2. Stop Outside Stuff from Coming In – Some of the worst pollutants your home will face are from outside. So, make sure you have doormats at every door and that your family and friends remove their shoes before coming inside. You can have a second mat inside as a friendly reminder that cleaning the shoes is not an option but a strict necessity.
  3. Humidity Helps – Humidity levels between 30% and 50% reduce the presence of dust mites, molds, bacteria and many other indoor pollutants. Air conditioning in the summer is helpful to reduce humidity. Additionally, look for sources of excess humidity like leaky pipes, standing water, or clothes drying.
  4. Radon Testing – We’ve recently discovered that Radon is the second leading cause of lung cancer in the United States each year and can be present in almost any home. It is not a location specific pollutant, so it’s important to have your indoor air tested for Radon as soon as you move into a new home. Once testing is done, have any problems repaired immediately.
  5. Cut the Chemicals – There are a number of high quality household cleaners that don’t contain chemicals. Avoid ammonia, bleach and other chemical laden cleaners that can inflame allergies and pollute the water supply. Your home will be just as clean and you won’t feel uncomfortable afterwards.

Proper cleaning and careful selection of compounds and what goes into your air will help you avoid creating new air quality problems in the house. Done right, this process will make everyone in your home feel more comfortable.
