Air Conditioning: Terminology to Know

Monday, April 29th, 2013

Living in Atlanta means that you depend on the effective, reliable performance of your air conditioning system a great deal during the course of the year. Whether you are ready to schedule air conditioning installation or you are considering your replacement options, there are likely some terms you will come across that you may be unfamiliar with. At Air Conditioning Experts, we believe that the more you know about your air conditioning system, the better off you are likely to be when you need it. Here is some basic air conditioning terminology to get you started.

  • HVAC:  This stands for heating, ventilation and air conditioning.
  • Load Calculation: When purchasing a new air conditioner you should hear discussion of a load calculation. This is an important part of the system design process. The load calculation will determine how large your HVAC system must be to keep your home comfortable.
  • Refrigerant: An important part of any air conditioning system is the refrigerant. This is the fluid that carries heat throughout your air conditioning system. The compressor of your AC compresses this refrigerant to a higher heat and pressure. It then goes to the condenser coil, where heat is absorbed by air and the refrigerant is converted to a high pressure liquid. The expansion valve allows it to expand to a cool gas. In the evaporator coil, air is blown across and across and heat is removed from the air, allowing it to cool.
  • SEER: You should also be familiar with different efficiency rating terminology. SEER is a measurement of how efficiently an air conditioner operates. It stands for seasonal energy efficiency rating.
  • MERV: The efficiency of an air filter is rated with a MERV, or minimum efficiency reporting value.

If you have any questions about the terminology you hear in regards to your air conditioning system, call the Atlanta air conditioning professionals at Air Conditioning Experts. We are always happy to share our expertise with you. Contact us today for more information.

Air Conditioning Repair: Is My Thermostat Broken?

Monday, April 22nd, 2013

Homeowners throughout the metropolitan Atlanta area are taking a good hard look at their air conditioners this summer.  One of the most common air conditioning problems concerns the thermostat. Although small and often taken for granted, the thermostat is your primary means of communicating with your AC unit. You rely on it to accurately sense the temperature and send the adjustments to the air handler when necessary. If you think your thermostat may be broken, call Air Conditioning Experts today for exceptional Atlanta air conditioning repair.

Here are some reasons to suspect that your thermostat may be broken:

  • AC won’t turn on. Your thermostat is an electrically wired device that senses the temperature in your home and adjusts the air handler accordingly. Whether you have a conventional or digital thermostat, your AC will not operate without a thermostat. If your AC won’t turn on at all, it might be a problem with the thermostat.
  • Inadequate cooling. While inadequate cooling may often be the result of a clogged air filter, cracked or loosely fitting ductwork, or blower motor fault, it can also be caused by a broken thermostat. If your thermostat no longer senses the temperature correctly, you may find that your home does not cool to your desired temperature.
  • AC won’t turn off. Your thermostat controls the fan setting on your cooling system. If you notice that it is too cold in your home—far colder than the temperature indicated on the thermostat—then your thermostat may not be communicating with the blower motor. If, after making any necessary adjustments, your AC still won’t shut off, you should probably turn it off manually. There could be a wiring fault with your thermostat.

If your thermostat is broken, consider not only replacing it, but also upgrading to a programmable thermostat. In addition to fulfilling all the functions of a thermostat in the home, a programmable model also allows you to customize your home settings by time of day and days of the week.

Why Do You Need Insulation in the Summer in Atlanta?

Monday, April 15th, 2013

We often think of insulation as keeping our homes warm throughout the heating season. That’s true: insulation does keep hot air in, and does significantly improve the energy efficiency of our homes in the winter. But insulation is equally important during the summer months, and many homeowners fail to realize the amount of energy they might save if they make sure their homes are well insulated throughout the year. If you’d like to speak to an insulation expert, call Air Conditioning Experts in Atlanta. We can show you the difference insulation can make for your home.

Forget fiberglass batting and foam panels; one of the best ways to insulate your home to maximize cooling this summer is with either spray foam or blown in insulation. Both are excellent solutions for retrofitting your attic, or adding insulation to poorly insulated walls or ceilings. They don’t require extensive remodeling or major demolition. Spray foam is an adhesive that can fill up any difficult to reach space, and blown-in insulation is flame-retardant recycled cellulose. Insulation keeps cool air in and hot air during the summer. Let’s look at the reasons why you need insulation this summer in Atlanta:

  • Energy-efficiency. By installing new insulation or replacing what’s there with a better material, insulation significantly reduces the amount of energy your system needs to keep cool this summer.
  • Reduced utility bills. Energy efficiency means cost-effectiveness. Not only will your use energy more economically, it will also save you money every day that you cool your home. Don’t throw your hard-earned cash out the window because of faulty insulation or the lack thereof.
  • Reduce condensation. Improving the insulation of your home can actually decrease any condensation problems you may have on your walls and ceilings by controlling the amount of heat transfer that takes place through the exterior of your home.
  • Eco-friendly. Insulation reduces energy costs and therefore saves non-renewable resources. It also reduces greenhouse gas emissions.

Still unconvinced? Talk to one of the insulation professionals at Air Conditioning Experts in Atlanta. We can show you in person why insulation is a great way to improve your home cooling system this summer.

Air Conditioning Tip 1: Improving Ductwork Improves Energy Efficiency

Monday, April 8th, 2013

You rely on your forced air heating and cooling systems throughout the year. The efficiency and effectiveness of these systems in turn rely on the integrity of the ductwork running behind the walls, underneath the floorboards and in the ceilings above you. If these are impaired in any way, the results can be damaging to the quality and comfort of your indoor air as well as to your wallet. When the time comes to improve your ductwork in your Atlanta home, call a ductwork technician at Air Conditioning Experts.

There are a variety of different reasons to improve the ductwork in your home. Here are just a few:

  • Energy loss- If your heated or cooled air is obstructed or inhibited in any way as it travels from your heater or air conditioner to the interior of your home, then it is costing you money. Energy loss is common in forced air systems, but it can be exacerbated by problems in your ductwork. Sealing up cracks, repairing leaks and other improvements can significantly improve the energy efficiency of your home.
  • Flooding- When water vapor cools in your ductwork, it can condense and leave behind small areas of standing water. This can create rust and can affect the integrity of your ducts in addition to becoming a breeding ground for microbial allergens.

There are still other reasons why improving your ductwork may be necessary. The ductwork in your home may have been installed incorrectly, for example. If your ducts were not installed by a certified and trained technician, then there is possibility that they are not working correctly. Furthermore, the components of your ductwork can become loose over time, opening themselves up for dirt, dust and debris. Ductwork can also be damaged during the construction of other projects in your home.

Energy efficiency and value go together. Making sure your ductwork is in solid working condition means improving the cost effectiveness of your home energy use. It also improves air quality and the comfort of your home. Don’t let poor ductwork get in your way. Call the Air Conditioning Experts in Atlanta today.

Air Conditioning Question 1: How Does Solar Air Conditioning Work?

Monday, April 1st, 2013

Air conditioning your home in Atlanta can be expensive. But what if, instead of combatting the sun’s rays, there were a system that used the benefits of the sun’s energy to cool your home? Solar air conditioning is just such a system, and Air Conditioning Experts can install this technology to provide an efficient and sustainable option for keeping your home cool. The technology is rapidly advancing and the cost of installation is reducing every year. Call us today for further information about our Atlanta air conditioning services.

There are two major types of solar air conditioning:  systems that use electricity from solar panels and evaporative coolers. A traditional air conditioning system combined with photovoltaic technology allows you to use solar power instead of power from the grid to cool your home. The photovoltaic panels absorb solar energy and convert it to electricity, and when there is not enough sun, a battery picks up the remainder. When there is more than sufficient sun, the solar panel charges the battery.

Another type of solar air is the evaporative cooler, also known as a solar powered chiller, which uses strictly solar energy to cool your home. Solar energy heats a refrigerant and therefore pressurizes it; when this pressurized refrigerant is released, it expands and cools the surrounding air. This is not unlike how conventional refrigeration works, except that you are drawing on a renewable and sustainable energy source. Although they require an initial investment in start-up equipment, solar air conditioning systems tend to be very cost-effective in the long-term, requiring only power collected from the sun.

Solar air conditioning is not only an innovative approach to reducing your carbon footprint, it can also significantly lower grid demand and load shifting during peak usage times and reduce electricity costs. To see if solar air conditioning is right for your Atlanta, GA home, call the Air Conditioning Experts today.
