Air conditioners are one of the unsung heroes of your household, delivering cool comfortable air for a very reasonable price. Summers in Hammond, LA, would be insufferable without them, and yet we rarely pay attention to them until they suffer a breakdown. Anytime there’s trouble with your AC, you should call in a trained professional immediately, but it may help to understand how the system functions on the most basic level. That can help you spot signs of trouble more readily and respond to trouble sooner rather than later. “How does my air conditioning system work?” you ask. We’ve provided a quick outline below.

How Does My Air Conditioning System Work?
Monday, May 11th, 2015Why Your Air Conditioning Systems Has Ice on It
Friday, April 3rd, 2015Air conditioners are a type of refrigeration system: using the action of a compressor to circulate refrigerant, they remove heat from one location to lower the temperature, and then exhaust the heat elsewhere. You may, at some point, notice ice developing along the inside of your air conditioner. Considering the chilled air coming from the system, this might seem like a normal side-effect of how an AC operates.
However, as we’ll explain below, the development of ice on an air conditioner isn’t something you want to happen. But please don’t try to solve the problem by scraping the ice off. This won’t work! Instead, call A–Professional Heating and Air Conditioning and we’ll help you with the necessary air conditioning repair in Hammond, LA that will restore your system. We are on call 24 hours a day for your convenience.
The Reasons Ice May Develop on Your Air Conditioner
- Low refrigerant: If the refrigerant lines in your air conditioner develop a leak and permit refrigerant to escape, it will often cause the evaporator coils to ice up. The reason this occurs is that the lower amount of refrigerant in the coils can no longer absorb enough heat to warm itself above freezing. The coils will remain cold and cause water moisture along them to turn to ice. This will further slow heat absorption, causing more ice to grow… and eventually you’ll have a solid block of ice over the AC coils and a system that won’t work at all. Repair technicians will need to seal the refrigerant leaks and restore the proper refrigerant charge for the air conditioner to work again.
- Dirt and grime along the coils: If contamination has entered the air conditioner’s indoor cabinet, it can cause the coils to become dirty. This will limit their ability to absorb heat through evaporation, and the coils will start to freeze water vapor along their length. You must have professionals detach the coils, defrost them, then clean them.
- Clogged air filter: An air filter that is too congested with dust and debris to allow sufficient warm air to enter the AC cabinet will cause the evaporator coils to stay too cold. Make sure that you change the filter once a month during the summer season when the air conditioner runs to avoid this problem.
At the first sign of ice on your AC, call for repairs. Our technicians at A–Professional Heating and Air Conditioning are ready around the clock to provide you with the professional air conditioning repair service in Hammond, LA that will find why the ice is appearing and fix it.
Hissing Sounds from Your Air Conditioning: What They Mean
Monday, June 16th, 2014An air conditioner, when operating normally, makes a predictable series of sounds: fans whirring, the compressor humming, and the occasional sound of condensate drainage. When another sound interrupts this pattern, it usually indicates that the AC needs to have professionals look into it and see if it requires repairs. Grinding and groaning sounds can point toward motors undergoing excess stress, clanging that a fan belt has come loose or a fan blade is bent, and clicking that a capacitor is about to fail.
In this post, we’ll address one sound in particular. It isn’t as loud and noticeable as some of the others, but it can warn of a problem as bad if not worse. When you hear a hissing noise from either cabinet of your AC, it means you probably have refrigerant escaping… and that requires professionals to perform air conditioning repair in Hammond, LA on the double, before your cooling system sustains serious damage that may even lead to requiring a replacement. Look to A–Professional Heating and Air Conditioning for the work you need, when you need it.
The Problems of Leaking Refrigerant
The refrigerant (sometimes called “Freon”) inside an AC is responsible for carrying out heat exchange. To do this properly, it must remain at a set level, known as a “charge,” that is balanced for a specific air conditioner. Refrigerant does not dissipate under normal circumstances, but the charge can start to drop if the AC develops leaks.
When the charge lowers, the air conditioner will start to lose its ability to absorb heat along the evaporator coil. The refrigerant in the coil will remain cold, and this will trigger the condensate moisture along the coil to freeze. The presence of ice will further restrict heat absorption, and even more ice will develop, leading to a cycle that will eventually conclude with a solid block of ice across the coil and a complete end of the cooling cycle.
Even more worrisome: a drop in refrigerant charge will cause an imbalance inside the air conditioner that will damage the components. The compressor—the most vital piece of machinery in an AC—can overheat and burn out due to a lowered refrigerant charge. A burnt-out compressor will have to be replaced, or even the whole air conditioner with it… the most expensive “repair” of all.
You do not want leaking refrigerant to continue for any longer than necessary. At the first hissing noise, or the moment after you spot ice forming along the evaporator coil, call for professional air conditioning repair in Hammond, LA. A–Professional Heating and Air Conditioning is available 24 hours a day to bring you the skilled work that will keep your AC cooling your home all summer long.
3 Common Problems with Air Conditioner Fans
Monday, June 16th, 2014Fans are an important part of your air conditioner’s system, particularly for the air flow and heat release process. Like other independent components of your air conditioning system, the fans can encounter problems, too, potentially leading to other issues with your system. Issues with your fans can have their own set of warning signs, something we’ve seen many times with air conditioning repairs in Covington. To help you pinpoint whether or not have an issue with one of your air conditioning system’s fans, our A-Professional Heating and Air Conditioning experts have put together some information for you on your AC’s fans.
Signs of Potential Fan Problems
Fans can be noisy when something is on the fritz. A couple of typical noises to look for might be:
- A clunking sound – which can indicate a loose or bent fan blade hitting or banging the inside of your outdoor unit
- A screeching sound – which can indicate a worn-out fan belt
Another symptom can come in the form of performance:
- Decrease in air flow coming into your property
- Warm air blowing into your property
Lastly you may have a problem with a fan if your air conditioner develops ice.
3 Most Common Fan Problems
Fans have several components, including wiring. Here are 3 of the more common problem areas when it comes to your air conditioner’s fans:
Motor Issues
Motors turn the fans’ blades, so if the motor of a fan is faulty, the fan won’t turn as needed. The fans’ motors are electric, and can fail due to burn out, overheating or problems with internal wiring. Typically this can be fixed by replacing the motor.
Electrical Problems
As we touched on above, each fan has its own motor; each motor is tied to your system’s electricity, but it also has wiring within it to make the motor run. Over time, wires can fray, become loose or disconnect; these things can cause the motor to run unevenly or not at all, possibly putting strain on your whole air conditioning system.
Problems with the Fan Blades
The blades on your fans are metal and can bend or break, particularly on the outdoor unit; they can also come loose from operation. If a blade is bent, it can hit other components around it as it spins, potentially causing damage. Loose and broken fan blades can be quite hazardous to your system, too, particularly if they disengage from the fan itself. Depending on what kind of shape they are in, bent, broken or loose fan blades may need to be replaced.
Don’t Ignore Fan Problems
The fans in your system are key components in the air flow and heat release/cooling process of your AC; if one of the fans is malfunctioning, it can cause a potentially bigger problem in your air conditioner down the road.

How You Can Tell You Need Air Conditioning Repairs
Thursday, May 15th, 2014Before the summer arrives, have any lingering air conditioning repairs taken care of. It’s likely that you’ve already needed to turn on your AC for a few days, so take some time to pay attention to its operation and look for any indications of faults or malfunctions. If you do notice anything amiss as we’ll go over in a moment don’t hesitate: call for professional technicians to come to your home and remedy the problem. Here are five common signs your AC needs repair that you should watch for early.

Signs It’s Time to Call for Air Conditioning Repairs
The clearest warning sign you can receive from your AC that it has operational problems is when it starts making strange noises. If the air conditioner makes grinding and stuttering sounds when it starts up, then it is “hard starting,” which could point to a number of issues in the motors or the compressor. Clicking sounds indicate capacitors about to fail. If you hear a hissing sound, like escaping gas, then you have a refrigerant leak and need to call for repairs to seal the leak and recharge the lost refrigerant as soon as possible.
Should you detect a loss in cooling power or a drop in airflow coming from the vents, the air conditioning could be experiencing major problems. Although you may feel tempted to let these problems go and hope they’ll get better, they won’t. You could have dirty coils, blocked airflow, broken fans, burnt-out motors… all of which will require professional repairs.
An indication of repair needs that some people often overlook appears on utility bills. As you get your first bills for the air conditioning season, compare them to the bills from the same time the previous year. If you see a surprising rise in costs, it might come from an air conditioning system that is running with a malfunction. Call for technicians to investigate and find out what’s wrong. Some repair problems are difficult to detect at first, but with knowledgeable HVAC specialists on the job, it will soon be fixed.
Schedule Maintenance As Well
Even if nothing seems wrong with your air conditioner this spring, you will still need to make a call to a trustworthy HVAC company to arrange for a maintenance visit. A tune-up and inspection will catch any repair problems that might otherwise escape your notice and give you time to have them repaired.
