AC Repair in St Charles

How Can A Professional HVAC Technician Diagnose And Repair The Air Conditioner In Your Home?

There are not many things that can bring comfort and relief to your home quite like an air conditioner. In fact, for many homeowners, central air is absolutely essential when the summer heat can be especially brutal in June, July, and August. However, air conditioners offer more climate control advantages than just cooling. They help to improve indoor air quality so everyone in the household can breathe a lot easier. Unfortunately, these powerful machines can and do break down, and there are several ways that we, as a professional HVAC contractor, can properly diagnose and repair the one in your home so you and your family can enjoy a comfortable summer.

As mentioned, just like all machines, air conditioners are subject to wear and tear over time. Although most units on the market today are designed to last a decade, they need to be properly maintained. Regular maintenance not only saves you money on energy costs, but also helps to increase the lifespan of the unit.

How Does The Central Air Conditioner In Your Home Work?

Air conditioners have evolved greatly since they were first invented in the early 1900s. With that said, the cooling cycle of the air conditioner has not changed very much. When the refrigerant chemicals enter into the evaporator coil, these chemicals absorb the heat that is in the home and the chemicals turn into a gas. The air conditioner will then start to pump the vapor from the refrigerant into the condenser coil. Once it enters into the compressor, the vapor becomes liquid again. During this process, the heat is removed from the home, and the refrigerant chemicals start the cycle is repeated. There is a specialized system inside of central air conditioners. This system operates on supply and return ducts, and these ducts help to circulate the cooler air through the home. As a result, occupants enjoy a comfortable and consistent temperature in the home.

Instead of spending a hot and sweaty summer without air conditioner, or trying to DIY diagnose and repair central air conditioner problems by watching online video tutorials, call a professional HVAC technician. A trained and certified HVAC technician will ensure that the repair is done properly and professionally the first time.

Central Air Conditioner Unit Is Making A Noise

It is normal for air conditioners to make occasional noises when they are working. However, rattling noises and vibrations are signs that something could be wrong with the unit.

These noises could be occurring for various reasons such as:

  • The unit was not installed correctly
  • There is no oil in compressor
  • Improper system charging
  • The unit is secured to the concrete pad
  • Wrong copper size

Some homeowners have also noticed that their air conditioners ‘squeal’ while they are running. This typically happens with older units that have belts. If the belt that connects the motor to the blower starts to slip, it can cause the squealing noise. If your central air conditioner unit is showing any of these signs, the unit should be immediately cut off and a professional should be contacted so the problem can be correctly diagnosed and the necessary repairs can be made.

The Unit Is Running, But Not Cooling Your Home

If there is air that is circulating through the vents, but the air is not cold, the unit may have an issue with the condenser coil. The condenser coil is the component in the central air conditioner that makes the air cold. It is important to keep in mind that the condenser fan will still run even when the condenser coil is not working correctly.

There are several reasons why a condenser may stop working:

  • Low refrigerant
  • Blown fuse
  • Circuit breaker that has tripped

No matter what the exact cause may be, this is not a repair that you should attempt on your own without a proper diagnosis. It is a better idea to contact a certified HVAC technician who will be able to inspect the unit more closely.

The Air Conditioner Will Not Come On

Sometimes, an air conditioner unit may not turn on, but the fan that is inside of the home will turn on. Again, this problem could have several possible causes. The very first thing that you will want to do is check the unit’s thermostat. If it is not working correctly, that could be the issue. If the thermostat is working correctly, the circuit breakers should be checked. There is a circuit breaker near the unit outside and there is another one in the home. If you suspect that it may be the breaker that is causing the problems, you can attempt to reset. However, if the breaker trips again after you reset it once, do not try to reset it again. Instead, call a professional.

Condensate Drain Clog

Over a period of time, dirt, grime and debris can begin to accumulate on the condensate drain. This type of clog can cause water damage if it is not detected and removed in time. Professional HVAC technicians can not only flush the system and remove the clog, they can also apply preventative measures to prevent another clog from developing in the drain.

Hot Blowing Air

So, what if you turn on your air conditioner and you feel hot air inside of cold air? This is also an issue that commonly arise if the condenser is not working properly. The condenser is one of the most expensive parts of a air conditioner unit, and this is one reason why the repair should only be done by a professional expert. In most cases, the condenser has to be replaced.

Central Air Installation Services

Whether you are building a new house and you are looking for an efficient way to keep it cool, or you are ready to replace an aging HVAC system, you will need to have a professional install the air conditioner. One of the main reasons why many air conditioners experience mechanical and efficiency issues shortly after installation is because of improper sizing. After the system has been properly sized, a highly trained and certified technician will need to ensure it meets the specifications set by the manufacturer.

Because you depend on your air conditioner to keep your home cool in the summer, it is important to find a reputable and professional HVAC technician who will repair and maintain your unit.
