Air Conditioning Repair Tip 3: Common Evaporator Coil Problems

Monday, July 29th, 2013

When you turn on your air conditioning system, it uses a number of different components to remove the heat from inside your home. The evaporator coil is one of the most important parts of the whole system and there are a number of common things that can go wrong with it. We wanted to put together a quick explanation of what the evaporator coils do and what some of the common problems it may have. If you’re experiencing any of the issues below, don’t hesitate to call Air Conditioning Experts for air conditioning repair in Atlanta.

How Evaporator Coils Work

In order to lower the temperature of your home’s air, your AC has to remove heat and exhaust it outside. To accomplish that, your air conditioner circulates a compressed refrigerant between two series of coils: the evaporator coils (which are located in the inside unit of your AC system) and the condensing coils (located in the outdoor unit).

The evaporator coils get very cold and a large fan in the indoor unit pulls in warm, moist air from your home and passes it over the cold coils. The refrigerant in the coils absorbs the heat from the air and then get circulated to the outdoor condensing coils where that heat is exhausted. The newly-cooled air continues past the coils, into your ducts and then into your home.

Evaporator Coil Problems

Here are a few common issues that could happen to your evaporator coils. If you’re experiencing any of these issues, call for air conditioning repair in Atlanta.

  • Dirt and dust – All of the air that travels into your home during cooling season has to pass over the evaporator coils. Any dirt or dust that is in the air can get caught on the evaporator coils, which prevents them from cooling effectively.
  • Moisture – If you’ve ever taken a cold glass outside on a hot day then you’ve had experience with condensation as water starts to collect on the glass. The same thing happens when the warm air from your home passes over the cold evaporator coils. This moisture can attract dirt, dust, bacteria and even sometimes mold if it is not properly drained.
  • Freezing – What causes your evaporator coils to freeze? It could be that you have low refrigerant in your system. But it could also be that the flow of air over the coils is insufficient. This can be caused by a clogged air filter or if the fan motor isn’t working well. Frozen coils can cause inadequate cooling and put extra strain on your system. If it is severe enough, it can prevent your AC from working at all.

How Air Conditioning Installation Affects Performance

Monday, July 22nd, 2013

If you’re in need of a new air conditioning system for your Atlanta home, you need it to perform well for years to come. That’s why it’s so critical to ensure that your air conditioning installation is handled by a professional. Without the technical expertise and experience of a trained technician, you simply cannot expect to receive the same amount of cooling performance. Your new AC is a major investment of resources, so it’s important it be well taken care of by a pro. Call Air Conditioning Experts today for quality, thorough Atlanta air conditioning installation services.

  • Size. The size of your AC may be the most important factor in a successful installation. Before the selection process, your tech will need to perform a comprehensive load calculation. This involves a series of measurements about the size of the home, as well as other factors related to the design of the home itself. This is an incredibly important step, one that can make or break your AC and the future of your comfort. The BTU output and tonnage of the AC must match the home. If it is too small, this can result in inadequate cooling, energy inefficiency, as well as possible system damage. If it is too large, this can result in the inability to control the temperature, as well as increased energy costs.
  • Refrigerant. During installation, your AC is “charged” with refrigerant. This chemical is designed to change temperature and phase (liquid to gas, gas to liquid) under different pressure conditions. It’s essential that this charge be the same throughout the unit’s operation. A successful installation will make sure that it has the right charge to give you optimal cooling performance.
  • Connections. A comprehensive whole-home cooling solution is not a wall-unit AC. There are various connections that need to be made between the components. For example, the lineset that connects the refrigerant lines between the indoor and outdoor units needs to be handled correctly. Any error in the installation can cause numerous future problems.

Why Your Air Conditioning System is Icing Up

Monday, July 15th, 2013

Are you wondering why there is ice on your AC’s coils? An iced-up system is not a good thing, it means that there is something wrong with the operation of your AC. Your evaporator coil resides in the indoor air handler, and it circulates a very cold liquid refrigerant that cools with the warm indoor air.  There are numerous reasons why your indoor coils are icing up, and in today’s post, we focus only a handful of the most prominent. At Air Conditioning Experts, we strive to keep our customers well informed so that they can identify problems or maintenance needs before they become major repairs or premature replacements. Give us a call today if you’re in need of air conditioning services in Atlanta.

  • Low refrigerant: During installation, your AC was charged with a certain amount of refrigerant. In theory, this “charge” should remain the same throughout the entire life of the AC, but there are a number of factors that can make your refrigerant levels drop. Even a microscopic puncture in your coils or elsewhere in the system can reduce energy efficiency and performance. One of the side effects of having low refrigerant occurs when your indoor coils ice up.
  • Clogged air filter: Another frequent cause of ice on your coils comes as a result of a clogged air filter. Your air filter is designed to prevent the accumulation of dust and debris on system components such as the coils. But if the filter itself becomes clogged with the debris, then you may have an airflow problem. When the cold air builds up inside the air handler, then it can result in those coils becoming iced over.
  • Duct damage: Damage to your ductwork can also cause your coils to ice over. For example, if your ducts become crimped so that airflow is blocked, then this problem can result.

Call Air Conditioning Experts today if your air conditioning system is icing up.  We offer 24 hour AC repairs to the Atlanta area.

Air Conditioning FAQ 3: AC Installation Steps

Monday, July 8th, 2013

Having a new air conditioning system installed in you your home is a big decision. Here at Air Conditioning Experts, we often get asked about how the process actually works and wanted to shed some light on exactly what steps need to take place. If you need Atlanta air conditioning installation make sure ha you work with a professional contractor. The process will likely go a lot smoother if you do.

No matter what kind of air conditioning system you need to have installed, it is usually best to have it done by a professional contractor.  Here is a quick explanation of the process and how it works.

  • Finding the right sized AC – One of the first and most important steps in the air conditioning installation process is to find the right-sized system. If you get an AC unit that is too small or too large it could cause serious issues of your home’s comfort.
  • Efficiency rating – Most air conditioning system are given a Seasonal Energy Efficiency Ratio (SEER) rating which lets you know how efficient the system is. The SEER rating is determined by measuring how much cooling the unit delivers over a season and how much energy it consumes to do so. More efficient air conditioners tend to me more expensive though, so you have to make sure your new system fits both your energy and budget requirements.
  • Installing the unit – Finally, after making sure that you have the right system for your home, that it meets your cooling needs and your budget, then comes the actual installation. Most air conditioning systems are “split” which means that they have an indoor unit that is connected to your ductwork and an outdoor condensing unit. We’ll install both systems, hook them up to your home’s electrical system and then test them to make sure that they’re working well.

Have a Safe and Happy 4th of July!

Tuesday, July 2nd, 2013

The 4th of July will forever hold a very special place in the history of the United States of America. On this day in 1776, the second Continental Congress approved the Declaration of Independence.

Not only is Independence Day an important day in our nation’s history, but for many people it is a day that is filled with memories from celebrations of years past. Fireworks, barbeques, baseball games, fairs, carnivals, patriotic music and ceremonies are all scattered through our memories as we’ve participated in annual parties, get-togethers, picnics and family gatherings throughout the years. John Adams, our 2nd president, was right when he said that our Independence Day “…ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations, from one end of this continent to the other, from this time forward forever more.”

The 4th of July is truly a day to enjoy but also to remember and respect the sacrifice that many brave men and women made over 200 years ago to give us the freedom that we cherish today. However you celebrate Independence Day, make sure that you take a moment to remember what this day is really about.

We wish you a safe and happy 4th of July!
