Does This Sound Mean It’s Time for Air Conditioning Repair?

Monday, June 24th, 2013

You should expect a certain amount of sound from your air conditioning system. After all, it’s a mechanical system with various moving parts and types of airflow. Many homeowners throughout our service area wonder about whether their air conditioners are making the right sounds or whether they should be worried. However, sounds are notoriously subjective and really require in-person diagnosis to understand what might be going on. But it’s better to be safe than sorry. If you notice a loud or unexpected shift in the sound of your AC, chances are that there’s something wrong with its operation. If you’re in need of air conditioning repair in Atlanta, GA, don’t hesitate to call Air Conditioning Experts today.

Let’s look at a few of the most common sounds:

  • Hissing: If it sounds like there is an air leak in your ductwork, then there may indeed be a small crack, hole, or loose connection somewhere. This can happen over the years and you may need to have them sealed or otherwise repaired to cut down on energy loss. But if you hear it coming from the indoor or outdoor unit, then it may be an indication of a refrigerant leak. This is the primary cause of low refrigerant, which can lead to inadequate cooling and system damages.
  • Banging: A loud banging sound can be annoying. But beyond the inconvenient noise, it can also indicate a problem causing physical damage to your AC. There could be a bent fan blade in your blower, or some other loose component that is moving around within the housing.
  • Grinding: If you notice a grinding sound, then it is probably something in the compressor or blower motor. If the bearings are dry inside a motor, then they lack the lubrication necessary to reduce friction and thermal stress.
  • Rattling: A rattling sound can indicate an issue with a loose panel or some other loosened component that needs fastening.

There are numerous sounds your AC can make during its operation, but make sure you get any strange or unusual ones checked out as soon as possible. If you’re in need of air conditioning repair in Atlanta, GA, don’t hesitate to call Air Conditioning Experts today.

Air Conditioning Question 2: Why Go Ductless?

Monday, June 17th, 2013

If you’re in the market for a new AC, then you have a staggering range of options available to you, from conventional central air and heat pumps to ductless mini split, geothermal, and solar air conditioning systems. With the exception of the ductless mini split, all of these systems use extensive ductwork in the walls, ceilings, and floors of your home to remove and distribute air. But, while ductwork has become a standard feature of homes that need cooling solutions, that’s no longer necessary with the latest developments in ductless technology. There are some good reasons to consider going ductless. For air conditioning services in Atlanta, call Air Conditioning Experts today!

  • Energy efficiency: Ductwork can account for up to 30% energy loss in your home. That’s a substantial volume of cool air that you’re paying for. Even with duct sealing and routine cleaning, they can still suffer loss when they move through uninsulated spaces of your home, like the attic or a crawlspace. Ductless mini split systems are highly efficient, with SEER ratings of up to 27, making them some of the most energy efficient air conditioners on the market today, mainly because the air handlers sit directly in the living space, typically up to four units per outdoor compressor/condenser.
  • Zone Control: Because of their design, ductless mini split air conditioners offer you an unprecedented amount of control over your cooling. If you’re frustrated at the thought of cooling the kitchen while everyone sleeps upstairs, then you’re probably looking for a way to customize each zone of your living space. Perhaps your kids like their room at 75 °F, but you enjoy a 70 °F. This is no longer a problem. This will not only improve your comfort, but also increase the energy efficiency of your home.
  • Air quality: If you’re bothered by allergens every cooling season, or by the amount of dust that can collect in ductwork, then consider going ductless to improve the air quality of your home. Sleep, compact air handlers have a built-in air filter to distribute cool air directly into your living space, without it having to pass through dusty ductwork.

Speak to your local AC technician to see if a ductless air conditioning sysem is right for your home. For more information about air conditioning in Atlanta, contact Air Conditioning Experts today!

Having Air Conditioning and Indoor Air Quality Issues?

Monday, June 10th, 2013

Considering the heat and humidity of the Atlanta, GA summer, it’s important recognize the relation between air conditioning and indoor air quality. Whatever type of air conditioning you have, you need to ensure that it’s not only performing effectively and efficiently, but that it is also supporting a high level of indoor air quality. We’d like to explore this relation in this post by discussing a few ways your Atlanta, GA air conditioning and indoor air quality issues intersect. 

  • Dehumidification: As you may already know, your AC is a natural dehumidifier. When warm indoor air is brought into the air handler, the heat is absorbed by the cold liquid refrigerant circulating through the evaporator coils. As the air cools, the moisture in the air condenses on the coils. But sometimes this inbuilt dehumidification isn’t enough. A whole-home dehumidification system can integrate directly with your air conditioner so that you can control the relative humidity of your home. Because much of our discomfort is due to humidity, and not just temperature, so you might be able to cut down on your energy costs and increase your comfort with a whole-home dehumidifier.
  • Dust and other debris: It won’t matter how cool the air is in your home if it’s of poor quality. Fortunately, there are aftermarket upgrades that can significantly improve your indoor air quality. If you have lots of dust and other debris circulating through your home, then consider installing a whole-home air cleaner or air purifier. Both mechanical and electronic cleaning systems can keep your indoor air and your AC clean.
  • Airflow:  Good airflow is critical to air conditioning performance and energy efficiency. Over time, however, dust and other debris can build up inside your AC system and the ductwork; in both places, it can cause serious disruption to both the warm indoor air extraction process and the cool air distribution process. Ensuring that your system is routinely cleaned is a great way to prevent airflow issues.

Air Conditioning Repair Question 2: Are My Ducts Damaged?

Monday, June 3rd, 2013

If you have a forced air distribution system, then you may already know how important your ductwork is to your home comfort. Your air conditioning would simply not be possible without it. They integrate directly with your indoor air handler, which also houses the evaporator coils that are responsible for the actual cooling of your air. With professional installation and routine maintenance, your air conditioning system will be in good operating condition for years to come, but because of the extensiveness of your ductwork, and its tendency to undergo significant wear and tear over years of service, there may come a time when you need to have your ductwork professionally inspected. For professional Atlanta, GA air conditioning repair, call Air Conditioning Experts today!

If you don’t know whether your ducts are damaged, here are some signs that indicate there might be a problem:

  • Inadequate cooling: When ducts become damaged, the first sign is a disturbance in airflow. As the indoor air handler sends your conditioned air throughout your ductwork, any cracks, leaks, or loose connections will permit that air to seep into unoccupied and unused parts of your home, such as the hot attic, or even between the walls. Even small breaches in the integrity of your ducts lead to significant loss of performance over time.
  • Energy inefficiency: With poor performance comes energy inefficiency. Even new systems with high SEER (Seasonal Energy Efficiency Ratio) ratings will suffer significant energy loss. Damaged ductwork can account for up to 30% of energy loss. If you notice an inexplicable rise in your energy bill, the reason might be faulty ductwork.
  • Poor indoor air quality: Depending on your home and how the ductwork moves throughout your walls and ceilings, if it’s damaged it might be circulating all sorts of particles through your home air, fiberglass from the insulation, or dust from the attic, even pollen directly from the outside air!

The integrity of your ductwork contributes significantly to the efficiency and effectiveness of your AC system. For Atlanta, GA air conditioning repair service, call Air Conditioning Experts today!
