Air Conditioning Noises You Should Never Ignore

Monday, August 6th, 2018

Air-Conditioner-TechAir conditioning problems come in many forms, some of which are easy to spot, and some not so much. We recommend that you have a professional conduct maintenance on your air conditioner every year, so you know that it’s ready for the added strain of the summer season. Preventive maintenance is not a guarantee, though.

There is still a chance that you can have problems come up with your system between appointments, which is why you need to be sure to keep an eye out for signs that your air conditioning system is in trouble. One of the most common ways to tell if your air conditioner is in trouble is to listen for odd noises coming from the system. (more…)

Why Does My AC Keep Tripping the Circuit Breaker?

Monday, August 1st, 2016

It’s the middle of a hot day, and suddenly the air conditioning system that’s keeping your home cooled down and pleasant shuts off. You go to the circuit breaker panel to check on it (something you should always do whenever a large appliance in your house stops working) and find that the breaker for the AC has tripped. You reset it, turn the AC back on… only to have the circuit breaker trip again not long afterwards. And it happens again and again.

Air Conditioning Myth: “Noisy Is Normal”

Monday, July 18th, 2016

An air conditioning system cannot run in complete silence. Regardless of how far technology develops to lower the sounds coming from the motors, compressor, and fans, there is no way that a AC can be designed and manufactured to work without creating any noise volume.

However, the idea that it’s normal for an air conditioning system to work noisily each time it comes on is also false. There’s a threshold of sound that an AC shouldn’t cross. If your home’s cooling system begins to become what you would call “noisy,” then it’s time to either have it repaired… or have it replaced. (more…)

Air Conditioner Short-Cycling: What It Is, What Causes It?

Monday, June 6th, 2016

One of the more common problems that air conditioning systems encounter is something called short-cycling. This is when the air conditioner starts up and runs for only a short time before shutting down, then turns on a brief time later, getting caught in a start-and-stop repetition. This is a serious problem for an air conditioner because it places immense strain on its components, particularly the compressor. The amount of energy that short-cycling drains will also result in a steep rise in bills. Because the AC won’t be able to complete its full cooling cycle, it will also result in a poor distribution of cold air through the rooms. (more…)

Help: My AC Won’t Shut Off and There’s Ice on It!

Monday, May 30th, 2016

You may have heard that ice appearing on an air conditioning system is not a good sign… and it’s true. An air conditioner doesn’t use ice as part of the process of cooling down a home. What it actually does is use chemical refrigerant that moves through a process of evaporation and condensation to absorb heat from inside a house and exhaust it to the outside. If ice develops during this process, it means something has gone wrong that’s triggering water moisture to freeze along the evaporator coil. (more…)

The Dangers of Low Refrigerant in an Air Conditioning System

Monday, May 2nd, 2016

People often misunderstand the role of refrigerant (a.k.a. “Freon”) in an air conditioner. Refrigerant is not a type of fuel: an AC doesn’t use up its refrigerant as it runs the way that a car uses gasoline or a cell phone drains its electrical charge. Refrigerant remains at the same level in an air conditioner as it moves between liquid and gaseous states, absorbing heating through evaporation and then releasing it through condensation.

Why Is My Air Conditioning System Becoming Inefficient?

Monday, April 25th, 2016

As the season for air conditioning gets underway, make sure to take a close look at your electrical bills each month to see if the AC is maintaining its usual energy efficiency. If you notice bills rising steeply, you should call repair professionals to look into the problem. Below are some reasons that your AC might be losing its energy efficiency. (more…)

Why Is There Ice on My AC?

Monday, June 15th, 2015

Seeing ice buildup on certain parts of your air conditioning system may seem normal, especially if you feel the area that is covered in ice, because it will be very cold. But we can tell you without hesitation that this isn’t normal and is indicative of one of several problems with your air conditioning system. Scraping off the ice does not fix the problem because the ice is a symptom of the problem, not the problem itself. So what can cause ice to build on your air conditioner? Let’s take a look. (more…)

Air Conditioning Repair Guide: The Problem with Dirty Coils

Wednesday, August 20th, 2014

There are two sets of coils in your air conditioning system: the condenser coils and the evaporator coils. Each set plays an important role in the heat release and cooling process. When something is wrong with the coils, it affects the refrigeration cycle, which can impact your whole system. The coils are intricate, and because refrigerant flows through them, it is important to hire trained professionals to handle any air conditioning repair in Arden, NC that involves your system’s coils. Comfort Central, Inc., technicians are here to help you with any AC repair need you may have, so don’t hesitate to call us.

What Are the Coils?

The coils in your air conditioning system are narrow, serpentine tubing made of copper covered by thin, metal fins. In the refrigerant cycle of your AC, the condenser coils release heat from hot, high-pressure gaseous refrigerant that flows into the condenser coils from the compressor. Conversely, when refrigerant flows into the evaporator coils, it is a cool, low-pressure gas that absorbs heat from your indoor air as provided by a return duct. The blower (fan) blows this warm air over the coils, where the heat is absorbed, and the resulting cool air is blown into your home through the ductwork.

How Does Dirt Affect Coils?

Through normal use, the coils in your air conditioner can become dirty. Dirt and dust cling to the coils, and if allowed to build, can create a layer that acts as insulation. Anything insulating the coils inhibits the correct operation of them: the condenser coils will not be able to properly release heat, and the evaporator coils will not be able to absorb heat. Once the refrigeration process is imbalanced, the entire operation of your system can be compromised.

Signs of Dirty Coils

There are a few key signs that you may have dirty coils:

  • Decrease in air flow
  • Increase in refrigerant pressure drop
  • Warm air blowing into your home
  • Strain on your compressor

Dirty coils can disrupt the operation of your air conditioner, or even lead to breakdown. The best way to keep your coils clean is with bi-annual maintenance. During any maintenance appointment, your coils are thoroughly inspected and cleaned of dust, dirt and debris. If you are seeing the signs that your coils may be dirty, call Comfort Central, Inc., for air conditioning repair in Arden, NC right away.

How Air Conditioning Repair May Result from Poor Installation

Thursday, August 7th, 2014

The money you think you’ll save with an inexperienced installer—or even trying to take on the work yourself—will vanish under a mound of repair bills from numerous calls to technicians to keep the AC working.

Start off right with your new air conditioning and contact the trained staff at Comfort Central, Inc. It’s vital that you have professionals handle installing a new air conditioning system for your home. This is not only because amateur installation risks leaving you with a cooling system that doesn’t work correctly (or may not work at all), but also because shoddy installation can lead to numerous unnecessary repair issues cropping up. We handle installation for many types of ACs, including ductless mini splits and high velocity systems. And should you need air conditioning repair in Asheville, NC, we have you covered there as well.

Here are some of the repair problems that may arise due to amateur AC installation:

Ineffectual and damaged condenser

The condenser is the outside unit of an air conditioner, and it needs a proper foundation and placement in order to do its job effectively. Poor installation can place a condenser where it cannot vent correctly, and this will lead to poor cooling. Worse, the condenser can pull in debris from a crowded region around it, leading to damage to the fan, compressor, and other components. Professionals will make sure the condenser is installed in a safe, clear location.

Electrical troubles

Most repair issues with air conditioners originate from the electrical systems. If the AC is not correctly connected to the house’s power system, it can lead to the air conditioner constantly tripping circuits or unable to draw sufficient power to run.

Damage through the air ducts

A central air conditioner connects to the ductwork of a home. If it is badly connected, it will lead to air leaks that will not only lower the cooling ability and a drop in airflow, but also allow dust and debris to enter the ductwork and find their way into the AC cabinet, where they can damage motors and other components.

Wrong refrigerant charge

Part of installing an air conditioner is to fill it with the right amount (“charge”) of chemical refrigerant. Amateur installation could result in a charge that is either too high or too low, and both will lead to serious problems throughout the AC, such as frozen coils and an overheated compressor.

It’s easy to avoid all these troubles, some of which can be costly to repair, by going to professionals in for the work in the first place. Comfort Central, Inc. will help you avoid unnecessary air conditioning repair in Asheville, NC with professional installation from trained technicians. We will see that you have the right cooling system, installed fast and right the first time. Give us a call today to schedule your next AC service appointment.
