Insulation Question: What Is R-Value?

Friday, June 27th, 2014

During a warm summer day, would you rather stand outside waving a hand fan or wearing a thick wool coat? Of course you’d pick the fan; who would put on a thick coat during the summer? But your home does need a thick coat for summer weather: insulation. The fiberglass bats, spray foam, and blown-in insulation in the walls and ceilings serves as a barrier to keep out heat during the summer, much the way that they keep heat trapped inside during winter.

However, not all insulation is made equal. To determine how well a piece of insulation prevents the movement of heat, you look at the insulations “R-Value.” We’ll explain what R-Value means so you’ll have a better idea how to pick the right insulation to make your home more energy-efficient.

You will need the help of professional insulators to get the best job done. Call Air Conditioning Experts, Inc. when you are looking for insulation in Marietta, GA.

The basics of R-value

R-value measures how much resistance to the movement of heat through conduction a material offers. It depends on the type of insulation, its thickness, and its density.

R-value is determined in a laboratory through the following equation: temperature difference X area X length of exposure divided by heat loss. The resulting numbers range, but for most insulation, R-19 is common.

The higher the R-value, the more the material slows down heat movement. However, higher R-value doesn’t necessarily mean better insulation, since there are more factors involved in determining insulation quality: R-value only measures the movement of heat through conduction (contact) and not through convection or radiation.

Because other factors are involved in the quality of insulation that goes beyond R-Value, you need to have experts help you with selection and installation. The highest R-value blown-in insulation won’t provide you much heat protection at all if the installer put it in shoddily, leaving behind large air gaps where heat can simply escape around the material. Compressing a material unnecessarily will reduce its R-value. Also, the wrong type of insulation put into parts of a house will have scant insulating power no matter how high the R-value. Don’t let the consumer obsession with R-value trick you into simply buying the highest rated insulation you can find and try to put it in yourself.

Call Air Conditioning Experts, Inc. for the work with insulation that will balance out R-value with other important factors, and then combine them with superb installation services. We offer new insulation service as well as replacement for your old insulation in Marietta, GA that will ensure you get the most value from your home’s insulation for a cooler summer and warmer winter.

How Commercial HVAC Maintenance Benefits My Business

Friday, June 20th, 2014

Maintaining a comfortable work environment, both for your employees and your clients/customers is crucial for running a successful business. The important word here is “maintaining.” The finest and most extensive comfort system for a workplace won’t mean much if it doesn’t continue to do its job year after year without repeated failures and repair needs. Commercial HVAC systems require stringent, professional maintenance from specialists to keep them efficient and effective.

Make sure that you schedule regular preventive maintenance for your company’s HVAC system with Air Conditioning Experts, Inc. A yearly visit from our technicians specializing in commercial HVAC maintenance in Atlanta, GA will make sure you enjoy these important benefits:

Reduced operating costs

You keep a close watch on your company’s budget to make sure that you maximize profits by avoiding unnecessary expenditures. Your HVAC system is the definition of a necessary expenditure, but without regular maintenance to keep it clean and tuned up, it can turn into a unnecessary expenditure. After only a year without maintenance, an HVAC system will lose, on average, 5–15% of its energy efficiency. After a few years you could be paying 25% more than you once did. Thanks to routine maintenance, your HVAC system will maintain 95% of its efficiency for its complete service life.

Fewer repair issues

Here’s another important statistic to know about HVAC systems: 85% of the repairs they need can be been avoided with preventive maintenance. You don’t want to add on numerous repair charges to your budget each quarter just to keep your air conditioning and heating working. And you also don’t want the disruption of needing to have service on the system on a regular basis.

Avoid work-halting shutdowns

The worst-case scenario with a commercial HVAC system is when the air conditioning or heating shuts down entirely. This is especially a problem during an Atlanta summer, with high heat and humidity that can make a workplace almost unbearable without a working air conditioning system. Maintenance reduces thee chances of a surprise breakdown by catching possible issues early and having them repaired before they can threaten your business’ productivity.

You can’t call up any HVAC maintenance company to supply your company with the necessary work. We will set up a maintenance program that will deliver you the yearly service you need to keep your company cool or warm without bleeding excess money or risking a shutdown.

Condensate Problems in Your Air Conditioning in Atlanta, GA

Monday, June 9th, 2014

If you listen carefully to the sounds that your air conditioning system makes during operation, you will hear at intervals the drip and splash of water. Your air conditioner does not use water as part of cooling down your home (a chemical known as refrigerant, or “Freon,” is what circulates through the coils and lines), but water is a product of the evaporation process that occurs along the indoor coil. The sound of water you hear is the moisture along the coil dripping down into a shallow condensate pan and then a pump removing it out a drain.

Under normal circumstances, the removal of condensate from your AC will present no problems. But like any component in a mechanical device, the condensate drainage system can develop trouble that will require the assistance of professionals to remedy. At the first sign of condensate problems (as we’ll describe below), call for repairs for your air conditioning in Atlanta, GA from Air Conditioning Experts, Inc. We are on call 24 hours a day, 7 days a week for your convenience.

How your AC can develop condensate problems

The moisture that forms along the evaporator coil is water from the air that condenses along the coil when the cold refrigerant inside it absorbs heat from the air. In high humidity, a large amount of water will appear along the coil.

The amount of moisture that drips down into the pan should never present a problem, no matter the humidity. However, the condensate drain can become clogged due to algal growth—a common occurrence in humid Georgia summers—and stop draining the moisture. If this happens, the shallow pan will rapidly overflow and spill water inside your house. This will lead to water damage, an increase in humidity in your house, and the growth of mildew and bacteria. At the first sign of any of these, call for help.

The condensate pump can also break, which will lead to the pump failing to drain. Another problem you may encounter is when the condensate pan becomes detached from the drain or drain line, sending the water in the pan straight down to the floor.

Whatever the trouble with the condensate system for your home, professionals can take care of the problem. They can detach the pan, clean it, unclog or replace the drain, re-secure the drain to the pan, and repair the pump.

Allowing water to continue to drip from an air conditioner is a bad idea: not only will this cause expensive water damage, but it will eventually trip an overflow switch that will shut off the air conditioner entirely.

How Geothermal Systems Cool Your Home

Friday, June 6th, 2014

Geothermal systems represent a viable alternative to more traditional heating and cooling systems, tapping into the ambient temperature of the earth itself to do its job. When you get down below about five or six feet, the temperature under the ground remains at a constant regardless of what the weather is like upstairs. Geothermal systems run a series of tubes under the earth and then pump some form of refrigerant (usually a mixture of water and antifreeze) through them to facilitate a heat exchange with the ground. Here in Atlanta, geothermal systems have proven quite popular, particularly on property with a lot of square footage. Here’s a quick breakdown of how geothermal systems cool your home.

It starts inside your home, where warm or hot refrigerant is pumped through the central system and into the coils beneath the ground. The temperature under the ground stays set at about 55 degrees or so, which means that the heat from the refrigerant bleeds into the ground as it passes through. By the time it completes its cycle and returns to the house, it’s usually the same temperature as the earth. That, in turn, pulls heat from the air in the in-house portion of the system, cooling it and allowing it to be dispersed through your home with a fan. The process warms the refrigerant up again, just in time to send it back into the coils and start the process anew.

This is very efficient because you’re not expending any energy to warm or cool the refrigerant. The earth is doing that for you, meaning you only need enough power to circulate the liquid and run the fan blowing the cool air into your home. As a result, geothermal systems cost much less to run month-to-month than more traditional forms of air conditioning, saving you a great deal of money in the process. For more on how geothermal systems cool your home, or to schedule an installation session, call upon Air Conditioning Experts to help.
