The Best Ways to Heat a Small Space

Wednesday, March 11th, 2015

If a part of your home is not hooked up to your central heating system, you cannot get much use out of this room during the cooler months. Some homeowners attempt to install point-of-use single room heaters to compensate for this, but these are highly inefficient and cannot heat up the whole room as effectively as a forced-air heating system can.

If you’ve recently added onto your home, or if there’s a small space in your home that goes unused when it’s cold outside, call the experts at Cool Air Mechanical. We can install a new efficient ductless or high velocity comfort system for you small space heating needs in Decatur, GA. These systems are described briefly below.

Ductless Heat Pump

A ductless heat pump has all of the same components as a traditional heat pump, which is an air conditioning and heating system combined. The only difference is that these units don’t need any ducts. Instead, an individual blower unit is mounted high up on the walls or suspended from the ceiling, and it connects to an outdoor compressor unit. You can use multiple indoor units to heat or cool a whole house, or you can have one indoor unit for a smaller space. These are highly efficient in both the heating and cooling season.

High Velocity Comfort Systems

High velocity comfort systems use very small ductwork to deliver cool or warm air from your central AC and heating systems to the various rooms of your home. This flexible ductwork can move air from your existing air handler into any new room addition or you can have an entirely new system installed in your home. The small size of the air handler and ductwork means it can fit into multiple different areas of the house. And the flexible ductwork won’t require any renovating. It’s designed to fit into most structures with ease, as it can snake through the walls, attic, basement, or even a closet. However, the small size means it should not occupy too much of the space you need for other purposes.

The experts at Cool Air Mechanical install and service ductless heat pumps and high velocity comfort systems. Call us today for superior air conditioning or heating service for your small (or large) space in Decatur, GA.

Benefits of Rooftop Commercial HVAC Installation

Tuesday, January 13th, 2015

When looking into HVAC systems for your business, you have a few considerations to make that homeowners do not have to deal with. For one, you have to select a unit that can handle a much heavier load due to the square footage. For another, you have space to consider. Commercial HVAC systems are extremely heavy, and take up a lot of space. In most businesses, every bit of space is at a premium. You probably don’t have an entire large room to devote solely to your HVAC system. That’s where rooftop installation comes in. Let’s take a look at the benefits of rooftop commercial HVAC installation.

Saving Space

As previously mentioned, commercial HVAC systems require a great deal of space that most businesses don’t have. If you’ve got the room to put a literal ton of equipment in a basement somewhere, more power to you. But if you’re like most businesses, that just isn’t an option. That’s why rooftop installation is so popular for commercial HVAC systems. The equipment is out of the way, freeing up more room for you to conduct your business.

Rooftop commercial HVAC units are also quite convenient for any repair or maintenance work that has to be done. If a commercial HVAC unit ends up being installed in a back room or basement, it tends to be very difficult to gain access to all parts of the unit. Rooftop units, on the other hand, tend to be surrounded by plenty of open space, making them much easier to access and repair.

There is one thing you should consider when deciding whether to install a rooftop commercial HVAC unit. Inclement weather can affect rooftop units, due to their exposure. As long as you conduct regular preventive maintenance, this isn’t really an issue. If you live in an area with lots of rain or snow, however, take special care of your system or you may find yourself paying for costly repairs.

If you’d like to know more about the benefits of rooftop commercial HVAC installation, call Cool Air Mechanical. We provide commercial HVAC installation throughout Decatur, GA.

What Are the Advantages of a Furnace Installation in Decatur?

Wednesday, October 29th, 2014

A new furnace installation in Decatur can help you increase energy efficiency and comfort, all while offering a level of reliability that can last for years. But there are additional benefits to installing a new furnace, as we’ll outline below. Fall offers a great window of time in which to install a new furnace, and hiring experience professionals ensures that your installation will be done quickly, efficiently and correctly. If you are ready for a new furnace, call the people you can count on: Cool Air Mechanical.

Two Types of Furnaces

We carry two types of furnaces at Cool Air Mechanical: electric and gas. Each has its own way of operating and benefits:

Electric Furnaces

Electric furnaces use heating elements to heat air directly. A large intake fan at the bottom of the cabinet draws air into the cabinet and blows it over the hot coils. The newly-warmed air is then blown into the ductwork to your living spaces. Some of the benefits of an electric furnace are:

  • Very good energy efficiency – because electric furnaces do not burn fossil fuels, they can have an energy efficiency rating as high as 100%.
  • You do not need a gas line – some homes do not have access to a natural gas line, whereas electricity is widely available.
  • Safety – while no heating system is guaranteed to be 100% safe, there is no need to worry about toxic fumes with an electric furnace.
  • Clean – because an electric furnace doesn’t burn fuel to operate, the system stays clean, which is helpful when it comes to annual maintenance.

Gas Furnaces

Gas furnaces tap into the natural gas line near your home. The gas is fed into the combustion chamber where it meets with air and a flame erupts. This flame heats the heat exchanger, where the warm air is then blown into your home. Some of the benefits of a gas furnace are:

  • Fast, hot heat – gas heat is about 130 degrees. As such, it heats your home quickly.
  • Good energy efficiency – gas furnaces can have an energy efficiency rating as high as 98%.
  • Burns cleanly – gas burns the cleanest of any fossil fuels.

If you need help deciding what kind of furnace is best for your heating installation in Decatur, call Cool Air Mechanical today and schedule an appointment with one of our experts.

How to Install an Air Conditioner Quickly

Wednesday, August 27th, 2014

Here in Decatur, GA, scheduling air conditioning installation is a necessity for the cooling season, but many homeowners want to install their new system themselves to make sure the job is completed quickly. Do-it-yourself projects are popular among homeowners looking to save some money and gain experience working with a new medium. While some home installation jobs may be suitable for beginners looking to gain experience in a new field, air conditioning installation is not a do-it-yourself job. The quickest way to ensure your air conditioner is installed correctly is by calling a skilled technician with years of experience.

The first reason you should allow a professional to install your air conditioner is that you may not choose the proper size. You must have the correct cooling capacity for your home in order to cool it completely, and a system that is too small will not be able to handle the job. However, your air conditioner will continue to run to attempt to meet your temperature needs, causing wear and tear to your system which will ultimately result in a shorter lifespan. On the other hand, a system that is too large will run for shorter periods of time. When a system turns on and off frequently, it is called “short cycling.” This damages the compressor, a major part of your air conditioner that is costly to replace.

Furthermore, air conditioners are complicated systems. You must be able to mount the units correctly, charge refrigerant (a chemical that can only be handled by licensed technicians), and ensure proper wiring, which is not only difficult but also unsafe when not done by a professional. Loose mounts, low refrigerant, and improper wiring may all lead to major problems like compressor damage.

When you call Cool Air Mechanical, our experts will ensure proper installation and sizing on your new AC. Furthermore, the job will move more quickly than if it were performed by someone without much experience. AC technicians know which questions to ask and the proper measurements to make to install your air conditioner as quickly as possible. If you need air conditioning installation in Decatur, GA, give us a call today!

How to Tell You Need Commercial HVAC Repair

Tuesday, August 12th, 2014

If you manage a commercial property, you may be too busy to notice when your HVAC system needs repair. Of course, the easiest way to know whether repairs are necessary is if you hear complaints from your tenants, customers, or employees. But it’s important to catch repair needs before your system stops working in order to prevent further damage to your system or a costly replacement.

When you need commercial HVAC repair, the first step is calling a professional technician. But how do you know when it’s time to call? While any problem should be taken seriously, here are 3 signs that you need commercial HVAC repair in Decatur today.

Reduced Cooling and Heating

Commercial HVAC systems are designed and sized to cool or heat large spaces with many occupants. Reduced heating or cooling may mean that your system is the improper size, the compressor is damaged, there is not enough refrigerant, or any number of problems that may be somewhat serious. Alternatively, you may need thermostat replacement, so it’s best to have a technician locate the problem.

Uneven Temperatures

If some areas of the building are warm while others are cool, you’re bound to hear about it from the people in your building. Uneven temperatures may indicate problems with the ducts, zone control system, fans, or the thermostat.

High Bills

A good indicator that you have a hidden commercial HVAC repair need is unusually high bills. Heating and cooling a commercial property can be costly, so high bills are often expected. But when your bills spike without warning, there’s probably a part that needs repair. Calling for repair may help lower your bills, while calling for maintenance once a year can prevent such problems from occurring in the future.

When you need commercial HVAC repair, you should make sure you contact an experienced commercial HVAC technician. Commercial systems are much larger than conventional ones, and an inexperienced technician may be unable to locate repair needs, or the technician may take longer to assess and fix problems. Qualified technicians are trained on commercial HVAC systems for all repair and maintenance needs. Call Cool Air Mechanical today for commercial HVAC repair in Decatur.

Tools Used for Duct Cleaning

Tuesday, July 15th, 2014

Here’s a suggestion for cleaning your home’s air ducts: go pull out the vacuum cleaner from the closet that has the long hose. Unscrew the grate from over one of the room vents. Turn on the vacuum cleaner and push the hose down into the duct beyond the vent and move it around for a few minutes while it sucks up the thick clogs of dust, carpet and furniture fibers, pollen, and dander. Put the grate back over the vent, and move onto the next vent and start the process again.

It sounds so simple, doesn’t it? Yes… because it’s too simple, and it doesn’t work. In fact, there’s no “do-it-yourself” solution for cleaning your home’s ductwork. The extent of your ventilation system and the level of contamination that can develop inside it require professionals equipped with specialized tools to handle the job. Fortunately, it’s easy to schedule the work: just call Cool Air Mechanical and talk to our team of experts in duct cleaning in Decatur, GA. We will handle the work with the best tools available and the training to use them.

Professional Duct Cleaning Tools

  • Power vacuums: The vacuums used for duct cleaning are large, industrial strength machines that attach to your forced-air HVAC system to access the network of air ducts. These vacuums are capable of placing an entire ventilation system under “negative pressure” that causes contamination to lift away from the interior surfaces of the ducts. Once the vacuums have altered the pressure inside a ventilation system, they then use powerful suction to remove the majority of particles.
  • Agitation devices: This term covers a large number of rotary brushes and vacuum hose attachments. They are designed to snake deep inside vents on long cables to loosen debris from the walls of ducts (without damaging the duct material) and allow for easier removal. Agitation devices are used to target specific areas of trouble that a power vacuum might not be capable of affecting.
  • Video inspection systems: How can duct cleaners know they need to target certain areas? They use video inspection equipment that can enter the ducts to examine contamination levels and the sources of blockages that are causing airflow troubles. Technicians often use this high-resolution camera equipment to provide “before and after” views to show how effective other cleaning methods have been.

You should schedule regular professional duct cleaning in Decatur, GA (we recommend that most homes have cleaning done every other year) to protect your HVAC system and your indoor air quality. Call our duct cleaning experts at Cool Air Mechanical today for top-level professional services that make use of the finest equipment available.

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.

You can reach Cool Air Mechanical any time of the day or night when you need air conditioning service in Decatur, GA that has turned a bit… too frosty. We will fix it for you fast and right. Contact us today to schedule an appointment.

Causes of Inefficient Air Conditioning

Monday, August 5th, 2013

Air conditioning is the easiest way to stay comfortable despite heat and humidity of summer. When temperatures start to rise, you need a cool, comfortable living space to come home to, leaving the muggy outdoors behind. But if your air conditioning doesn’t function as efficiently as it could, that comfort can come at the cost of high electric bills. What are the causes of inefficient air conditioning? A few of the more important reasons are listed below:

  • Dirt: Dirt can build up on the coils and other components of the air conditioning system, while clogs can develop in vents and lines that interfere with the flow of air. If you don’t change your air filters regularly, they can become clogged with dust as well, reducing your indoor air quality and forcing your AC to work harder. Regular cleaning and maintenance can resolve this issue.
  • Low refrigerant: Refrigerant plays an important role in cooling the air in your air conditioning system. If it leaks or runs low, the AC must work harder to produce cool air. A trained technician can recharge refrigerant levels for you.
  • Leaks: Your ducts, fittings and other parts of your air conditioning system may spring leaks as they get older: causing cool air to vent out of the system instead of into your home where it belongs.
  • Improper size: In the AC unit is too small for your house, it won’t be able to cool effectively. If it’s too big, it will shut off too quickly and/or waste energy. Installing a properly sized air conditioning unit should resolve the problem.
  • An older system: Like any other piece of mechanical equipment, air conditioning systems become less efficient as they get older. You can delay the process by keeping the unit well-maintained, but sooner or later, it will need replacing. When installing a new air conditioning system, look for energy efficient units with a high SEER (Seasonal Energy Efficiency Ratio) rating.

When seeking solutions for inefficient air conditioning in Decatur, GA, it pays to speak with an expert. Contact the skilled technicians at Cool Air Mechanical about setting up a maintenance schedule or replacing your old AC unit with a newer, more efficient one.

Decatur, GA Air Conditioning Repair Needs: My Fan is Too Loud

Wednesday, June 26th, 2013

The extreme heat that can come along during a summer in Georgia necessitates a reliable, efficient performance from your air conditioning system. If you have any reason at all to believe that there is a problem with your air conditioning system, it is always best to address that problem as soon as possible. The longer you wait to do so, the greater the risk of serious damage to your air conditioning system. There are a lot of different components that comprise your AC, and any issues with even one of these components can lead to serious operational trouble if given the chance. Call the Decatur, GA air conditioning repair technicians at Cool Air Mechanical with any concerns you may have, such as a fan that seems to be operating too loudly.

There are a few ways in which your fan may exhibit signs of duress. One of them is with a loud humming sound. If your exterior fan is making a loud hum and does not seem to be starting up, you probably have a problem with your capacitor. The start capacitor in your AC gives your system a torque boost when starting up. A faulty capacitor may result in a fan struggling to get going.

A less technical, more mechanical issue may simply be that some component of the fan has slipped, been damaged or bent. If a fan blade is bent it may scraped against the interior of the unit casing. A slipped fan belt can result in a sustained whine until it finally breaks or causes the fan itself to break down. Improper lubrication is another major cause of a loud operation from your fan, and certainly one of the most desirable as it is an inexpensive fix. Whatever the cause of your particular problem, one thing is certain: it is always best to ensure that your AC repair needs are met as soon as possible.

To learn more about common reasons that your fan is too loud, contact the Decatur, GA air conditioning repair technicians at Cool Air Mechanical. No matter what is wrong with your fan, our team can resolve the problem promptly and completely. Contact us today to learn more.

Atlanta, GA Air Conditioning Question: Why Is My Air Conditioning System Not Dehumidifying?

Monday, April 15th, 2013

Air conditioning is necessary in Atlanta, GA, and homeowners throughout the area are making sure that their cooling systems are ready to go for the entire summer. As you start your AC back up after a season of non-use, you may find that it’s in need of repair or it needs a service tune-up. One common problem that we often hear about is when AC systems are not dehumidifying properly. As you probably know already, your air conditioner dehumidifies the air as part of its normal operation. When it’s not, then it probably indicates some kind of operational problem. For more information, or to schedule air conditioning repair in Atlanta, GA, call Cool Air Mechanical today!

Here are some possible causes of an AC system that is not dehumidifying:

  • Inadequate refrigerant charge: The “charge” is the level of refrigerant that circulates through your compressor pump, evaporator, and condenser. It’s imperative that your system have the correct amount of refrigerant at all times. If you have low refrigerant charge, then it’s possible that your AC system will not dehumidify the air.
  • Oversized system: If your AC does not dehumidify the air and also frequently turns on and off, then it is probably too large for your home. What happens is that the high-powered system cools the air at such a fast rate that the air does not spend enough time moving over the evaporator coil to be dehumidified. After your thermostat shuts off the cooling because your home has reached the desired temperature, there is still a lot of humidity in the air.
  • Dirt and debris in the system: One of the best ways to prevent damage to your system is to ensure that all of its components are clean and clear of any dirt and debris. If your coils are covered in dust, then you cannot expect it to work efficiently, and one of the potential outcomes is a lack of dehumidification.

If your AC system is not dehumidifying properly, then it requires professional attention. Make sure your AC performs well and efficiently this cooling season by scheduling Atlanta, GA air conditioning repair and maintenance with Cool Air Mechanical. Call today!
