Is Ice on My Air Conditioning a Reason to Call for Repairs?

Friday, May 30th, 2014

Ice appearing along the indoor coil of an air conditioner… that doesn’t sound so bad, does it? With all the chilly air blowing out from the vents, it makes sense that some ice might form on the system. No reason to worry…right?

No, wrong. An air conditioner should never start to develop frost anywhere along it; an AC does not produce cold; it removes heat, and ice can interfere with that action. If ice begins to appear on your air conditioner, there is a serious malfunction going on that needs immediate attention from professional technicians. Call up the specialists at Cool Air Mechanical for air conditioning repair service in Decatur, GA whenever you encounter trouble like this. Our team is ready to help 24 hours a day, 7 days a week.

What Ice on Your Air Conditioner May Mean

There are three common reasons that ice may begin to encrust the evaporator coil in the indoor cabinet of an AC:

  1. A clogged air filter: The air filter protects the interior of the air conditioner’s cabinet from damage, but should it become clogged it will lower airflow into the evaporator. The lack of warm indoor air crossing the cold evaporator coil will cause the coil to remain too cold, and water moisture will start to ice-over. This will block the crucial heat absorption along the coil and lead to a drop in cooling power. Change the filter once a month in summer to prevent this.
  2. Dirty coil: When dust contamination enters the cabinet, it will settle along the coil and block heat absorption. The refrigerant in the coil will remain at a lower temperature, causing moisture freezing that will continue to grow worse so more ice forms. You cannot clean the coil on your own; it requires technicians to remove it and clean it.
  3. Loss of refrigerant charge: If refrigerant starts to leak from the system, the coil will lose its heat absorption ability, once again causing a chain reaction of freezing across the evaporator coil and a decline in cooling. Low refrigerant can eventually damage the compressor, so this issue needs to be remedied immediately. Repair technicians will seal the leak and recharge the refrigerant to its proper level.

Whatever the cause for ice on your AC, have professionals look into it. You will start to feel a drop in cooling power soon, and trying to scrape the ice off not only won’t help, it might damage the coil and create refrigerant leaks.

Tips on Staying Open During Commercial HVAC Repair

Thursday, May 29th, 2014

As a business owner, you want as few distractions and interruptions to the regular work schedule as possible. This applies whether you run a restaurant or an accounting firm, or whether you have customers or clients. The idea of having technicians come to your business to perform vital repairs on your buildings heating or cooling systems sounds like a significant hassle that could even threaten to close down operations for a period. For this reason, some business owners are hesitant about scheduling repairs even when they desperately need them, but this is a far worse situation, as it means discomfort for everyone.

At Cool Air Mechanical, we offer services for commercial HVAC repair in Roswell, GA that will get the job done fast and right. We know how important your business is to you, so we will make every effort possible to reduce disruptions to a minimum and restore your cooling or heating as soon as possible.

Here are some tips you can use to make it easier to keep your business open and running during HVAC repairs:

  • Only hire experienced commercial repair personnel: Amateurs are out of the question; they won’t get the work done correctly and it will take them too long, creating unprofessional delays. But professionals who only have experience with residential systems will also cause problems, since they will not have the knowledge about how to keep themselves out of the way of day-to-day operations. Trained commercial specialists are skilled at the art of remaining as unobtrusive as possible so work can go on as normal.
  • Schedule the work during off (or slow) hours: We realized that when you have an emergency, you can’t control when you need to have the repair work done. But with a bit of planning, any other repair work can be scheduled during a time when you are either closed or only a small staff needs to be present. Many commercial HVAC repair technicians offer 24-hour, 7-days a week service to help companies that cannot afford to shut down their heating and cooling during the day.
  • Install rooftop packaged units: This is planning ahead, but it is an investment that is well worth it. A rooftop package unit is in an ideal position for repairs that will not get in anyone’s way. Although you will still need to worry about a temporary loss of heating or cooling during the work, the compact nature of rooftop units makes them fast repair jobs for skilled technicians.

Hiring the right service company is the key to making it through repairs without losing productivity or business. Cool Air Mechanical has the experience, equipment, and staff to keep your company running while we provide the necessary commercial HVAC service in Roswell, GA that will quickly return comfort to your workspace.

How Does Humidity Affect Air Conditioning Systems?

Friday, May 23rd, 2014

Your air conditioner is responsible for making your home comfortable during the hot months of summer, but that equation involves more than just lowering the temperature. Humidity plays a huge role in determining the comfort levels of your household, and the levels of humidity in your home can affect your air conditioning system accordingly. When it comes to air conditioning service in Dunwoody, GA, residents need to keep that in mind: our summers are as humid as they come, and if you’re not careful, it could adversely impact your AC unit.

Humidity refers to the amount of moisture in the air. The higher the humidity, the more moisture is present. This affects our comfort levels because we sweat to cool off. As the sweat evaporates off of our skin, it lowers the temperature of our bodies. However, if the humidity in the nearby air is too high, the sweat won’t evaporate, and our bodies won’t get cool. Human beings tend to be most comfortable with relative humidity levels between 25% and 50%. As you probably know, things can get much steamier here in the South.

Your air conditioning system can help somewhat. As it cools the air inside of its system, the humidity solidifies into beads of condensate, which drip into a pan and can then be carried out via a line. That helps lower the humidity in your home and make it more comfortable. Unfortunately, it also tends to put a lot of extra strain on your air conditioner, which ends up using more power than it should to keep your home cool, and if too much condensate builds up in the system, it can overflow into the rest of the system.

In cases where the humidity affects the air conditioning system unduly, you can install a whole house dehumidifier to keep it in check. Not only will it improve comfort levels overall, it will reduce the strain on your air conditioner and lower the risk of a breakdown. For this and similar upgrades to your air conditioning, Dunwoody, GA residents have an answer in Cool Air Mechanical. We have the personnel and experience to do the job right, so give us a call today!

How Commercial HVAC Installation Differs from Residential Installation

Friday, May 16th, 2014

Every building needs air conditioning, no matter what the size or purpose. But while residential homes require one kind of system to keep their interiors cool, businesses need an entirely different kind. Office buildings and retail businesses have a way of changing occupants more often than regular homes do, which means they need greater flexibility in regards to their cooling needs. They also tend to be much larger than residences, and need to support the occupants in the heat of the day. When it comes to commercial HVAC installation, Duluth GA has companies with the specialized skills required to do the job right. Here’s how commercial HVAC installation different from residential installation.

In most cases, both types of systems rely on a series of ducts to carry cool air throughout the home. Obviously, commercial buildings require a lot more ducts to reach a larger number of rooms. Moreover, those rooms often need to be able to tailor their temperature to fit their needs. A company on the first floor that uses a lot of computers will require more cool air to help keep those computers running than a storage facility on the second floor which just holds paper products. And since warm air rises, floors higher in the building will usually need more air conditioning power than lower floors.

Accordingly, commercial HVAC installation usually means installing multiple units to cover the entire building. The modular nature of the units means that they can respond to the tailored need of the building. If clients move in or out, you can simply add more units, or shut down those that aren’t seeing use. Such units are often installed on the roof, which keeps space concerns in check as well as making them easy to access in the event they need repair.

Because commercial HVAC installation differs from residential installation, look for companies with experience in commercial buildings to set up your system for you. If you’re looking for reliable HVAC services in Duluth, GA, look no further than Cool Air Mechanical. We’re dedicated to your complete satisfaction at every turn, so pick up the phone and call us today to make an appointment!

Why Should I Consider a Tankless Water Heater?

Thursday, May 15th, 2014

Most people are accustomed to traditional tanked water heaters, which sit in the basement or garage and carry water in a standing tank. But that’s not the only type of water heater you can use for your home. Tankless water heaters, which heat the water instantly as they travel to your faucet or outlet, offer a number of advantages over the more traditional models. Many services that offer water heater installation in Atlanta also handle tankless water heaters as well. “Why should I consider a tankless water heater?” you ask. We’ve provided a few compelling reasons below.

The main benefit is that it costs less to run than a traditional tanked water heater. A regular water heater needs to expend a lot more energy in order to maintain that amount of water. Tankless systems heat the water more or less as it flows, which saves a great deal of energy and costs much less in terms of monthly bills. (That also translates to increased speed as well. Because tankless water systems heat the water instantly, you don’t have to wait and run the water while it slowly warms up to the temperature you want.)

Tankless water heaters also benefit because they don’t require natural gas to run. This makes them extremely beneficial in houses that don’t have access to natural gas, such as cabins or vacation homes. No natural gas also means no toxic byproducts, making tankless systems a greener alternative to traditional models.

Finally, there’s the convenience of a smaller unit, which allows it to fit comfortably under the sink and in other easy-to-reach spots. That makes repairs much easier, which can be a godsend in moments when the unit doesn’t function the way it should.

Tankless water heaters tend to cost more to install than tanked models, and they function best when the demand placed on them is small (making them good for small families or vacation homes where they won’t see a lot of excessive use). But the benefits are tangible and make it much easier to consider a tankless water heater for your home. The experts at Cool Air Mechanical handle water heater installation in Atlanta all the time, and we can put in a tankless system with courtesy and care.

Check the Power Levels on Your New Air Conditioner

Friday, May 9th, 2014

Air conditioning installation in Atlanta involves more than just picking a model out of a catalog and letting the technician put it into place. You need to make sure it’s the right unit for your household, a process that may be trickier than it seems. An air conditioner is an expensive investment, and without proper preparation, you may get a unit that just isn’t right for your home. Consider the need to check the power levels on your new air conditioner, for instance. Getting those power levels right is extremely important.

You probably know that if an air conditioner isn’t powerful enough, it won’t be able to cool your home properly. What you probably didn’t know is that if the air conditioner is too powerful, it suffers from a similar problem. A/C units use much more power starting up and shutting down than they do simply running. If your unit is to powerful, it will “cycle” on and off rapidly, increasing strain on the system and wasting a great deal of energy.

Accordingly, you want your new air conditioner to adhere to what we call the Goldilocks Rule: neither too small nor too large but just right. Part of that involves calculating the square footage in your home (as a general rule, an air conditioner needs to generate about 25 British Thermal Units of power for every square foot), but variables can complicate the equation. For instance, if your home has a lot of insulation, it won’t need as much power to cool, while a house that gets a great deal of sunlight might need a more powerful unit to do the job.

A good technician will carefully check the power levels on your new air conditioner in relation to all those factors, in order to ensure that the unit is the most effective it can be. For air conditioning installation in Atlanta, the experts at Cool Air Mechanical can help. We pride ourselves on your total satisfaction and we won’t rest until you are completely happy with our work. Give us a call to set up an appointment today!

Signs of Compressor Problems in Your Air Conditioning

Friday, May 2nd, 2014

Just as you have symptoms when you are sick – a runny nose, cough, fever – so, too, does your air conditioning system. Pinpointing the source of the problem is the key to getting repairs done quickly and efficiently. You should always use a Cool Air Mechanical professional for your air conditioning repair in Atlanta, GA. Here is a short list to help you determine if it may be your compressor that isn’t working.

What Is the Compressor?

There are 3 major parts to every air conditioning system: the evaporator, condenser and the compressor. The compressor’s role in the cooling process is compressing the liquid refrigerant into gas. As such, if the compressor begins to malfunction, the heat exchange process is greatly inhibited.

Signs of Problems

  • No Cool Air
    A lack or total loss of cool air can be the first sign your compressor isn’t working well. When the compressor can’t compress and move the refrigerant along, the rest of the cooling/heat removal process breaks down.
  • It Gets Noisy
    Are you hearing a lot of noise coming from your outside unit? This may be a sign your compressor is experiencing problems. The normal sound of an air conditioning unit is a hum. If the compressor is not working properly, you may notice a hissing, clunking or rattling sound. The hissing comes from a loss of pressure in your compressor; the “noisy” sounds – rattling and clunking – could be coming from the compressor’s motor.
  • Hard Starts and Stops
    A third sign that your compressor may have a problem is when your air conditioning system struggles to turn on and off; it can also emit sputtering and jerking sounds. This happens because a system with a broken compressor cannot start or shut down properly. These are known as “hard starts.”
  • Breaker Trips
    Does the electricity to your AC keep turning off? If the compressor is working too hard, or if there is an electrical malfunction in the compressor’s motor, it can cause the breaker controlling it to turn off.

Call a Cool Air Mechanical Professional

Compressor repairs should only be handled by a Cool Air Mechanical professional. If you think you may be experiencing a problem with your air conditioner’s compressor, or are experiencing any other air conditioning problems, call Cool Air Mechanical today. We can handle your air conditioning repair in Atlanta, GA properly.

Mold Testing Question: What Does “Mold” Encompass?

Thursday, May 1st, 2014

Your home needs protection from mold growth to maintain a high level of indoor air quality. Experts can remediate mold through techniques such as fogging and targeting affected material with cleaning, encapsulation, or removal.

However, for proper mold remediation, your home needs to have mold testing (environmental inspection) to determine the cause of the mold growth and the particular types of mold that must be addressed.

What exactly does “mold” encompass? Although you are familiar with the mold that appears on old bread, you probably don’t know much more about what the inspectors will look for. In this post, we’ll go into detail about what mold testing covers and how some mold threatens human health.

Cool Air Mechanical offers mold remediation and mold testing in Atlanta, GA that will keep your home safe and comfortable. Call us today to schedule an environmental inspection.

Mold Inside Homes

Mold is a type of fungus that grows in multicellular filaments. (By contrast, yeast is a fungus that can grow as a single cell.) Not all mold growth poses dangers to humans, but a few common species do: mold testing targets these, although it will seek to eliminate all mold as a precaution.

According to the Center for Disease Control, the most common molds inside homes are Cladosporium, Penicillium, Aspergillus, and Alternaria. The molds that will affect indoor air quality are the ones that produce mycotoxins, which are responsible for the breathing troubles, irritations, allergic symptoms, and unique health problems that molds can trigger inside a home. These are referred to as “toxic molds,” even though the mold itself isn’t toxic; the spores it produces are.

The most problematic mold when it comes to health concerns is Stachybotrys chartarum, which can grow on fiberboard, paper, and within dust and lint. However, the danger level of Stachybotrys chartarum is irrelevant when it comes to mold testing, since, according to the CDC, “[i]t is not necessary… to determine what type of mold you may have. All molds should be treated the same with respect to potential health risks and removal.”

When you schedule mold testing, you target all the molds that might have developed in your house, regardless of their toxicity level. Expert mold testers will find where mold is growing and identify the methods needed to remediate it. Be assured that with professionals on the job, you will have all dangerous molds eliminated, along with the benign ones as well.

Cool Air Mechanical offers many services to improve your indoor air quality, from installing air filters to conducting mold testing, in Atlanta, GA. Call us today to learn how we can make your home a healthier place for your family.
