3 Unique Qualities of Commercial Air Conditioning

Monday, May 26th, 2014

A summer in Atlanta can be humid and brutal, but with the right air conditioning system working for your business, none of your employees, customers, or clients will take notice of it when they are inside the company workspace.

Commercial ACs are unlike residential ones in a number of ways, which is why you must always entrust the professional worked needed to install them and then keep them running to technicians with special training. You can’t turn to any HVAC repair contractor when your air conditioner starts to experience trouble that threatens your business.

Make sure you call a company like Air Conditioning Experts, Inc. that handles commercial air conditioning in Atlanta, GA for your commercial AC needs. 

3 qualities unique to commercial air conditioners

  1. The package unit: The most common type of commercial air conditioning system (as well as commercial heat pump) is the package unit. These are different from the standard split systems that you find in homes, where the evaporator cabinet and the condenser cabinet are kept in different locations, the former indoors and the latter outdoors. Package units keep all the necessary components—condenser, evaporator, compressor, fans—inside one larger unit installed outside. This is important for saving space in a business, keeping away extraneous noise, and allowing repair technicians to easily service the unit without disrupting workflow.
  2. The rooftop location: Although package units can be installed on the ground around a building, their preferable location is on the roof. This way the bulky cabinets remain out of the way and do not create visual pollution for a company. The space available on the roof means there is almost no limit to how much cooling power a building can have. The rooftop perch also makes the ACs less likely to sustain damage or suffer from vandalism.
  3. Specialized ventilation and humidity control: The size of commercial buildings and spaces makes it imperative that they receive proper ventilation. Since many business buildings cannot open windows to allow in outside air—unlike a residential home—air conditioners and heaters must have designs that permit outside air to enter. The air conditioners also have special humidity controls to compensate for the rise in moisture that can occur because of the entrance of exterior air; this is a major concern in a place that can become as humid as Atlanta.

Make sure that you have professional installation, repair, and maintenance work from commercial specialists. You don’t want to place your commercial air conditioning in Atlanta, GA in the hands of technicians unfamiliar with the above unique aspects. For your comfort and satisfaction, contact Air Conditioning Experts, Inc. today and put your trust in our almost 20 years of experience helping keep businesses comfortable.

3 Tools Used with Air Duct Sealing Operations

Monday, May 19th, 2014

The air ducts in your home carry cool air from your air conditioner (or hot air from your furnace) into the four corners of your house. In order for them to work effectively, they need to be sealed tight, but sometimes breaches occur. Fittings between separate parts can become loose or the ducts can suffer damage from some outside source, which opens the system up to the outside air. When that happens you need to call upon an expert to seal the duct and restore your system to full effectiveness. Otherwise, air will leak out, or unconditioned air will get sucked in, both of which will force your HVAC system to work harder to do its job. Here in Atlanta, duct sealing services are provided by a number of qualified companies.

3 Essential Tools for Duct Sealing

  • Duct Mastic. Duct mastics is a type of past which can be spread across the breach. When it hardens, it forms an effective seal against further leaks. Duct mastic works best on comparatively narrator breaches, where it can be applied without dripping down into the ducts.
  • Duct-sealing tape. This specialized silvery tape I used to secure the edges of any fitted parts covering the breach. Duct-sealing tape should not be confused with common duct tape, which ironically is woefully inadequate for sealing ducts. Normal duct tape can’t withstand the temperature changes the ducts undergo in the course of their operation, which is why specialized tape is needed.
  • Sectional seals. Sectional seals are used for larger breaches. They’re composed of the same material as the ducts themselves and can be shaped to fit the exact shape of the breach. The technician can use crimping tools to hold the piece in place, then duct mastic or other sealant to seal up the cracks around the edges.

In Atlanta, duct sealing services can be provided by Air Conditioning Experts, Inc. As our title implies, we’re experienced professionals with a wide array of knowledge about all manner of air conditioning issues, including duct breaches and the ways to deal with them.

If your ducts need a little help to get back up to speed, give the duct sealing professionals at Air Conditioning Experts a call today. You’ll be glad you did!

Are Ductless AC Repairs Different from Central AC Repairs?

Friday, May 16th, 2014

While no one wants to think about their new air conditioning system breaking down, at some point, you will need to conduct some kind of repair work. If you are in the process of choosing a new system and are researching what kind of potential repair work can exist with different types of air conditioners, you may have wondered about the differences between repairing a ductless air conditioner and a traditional split-system air conditioner. Air Conditioning Experts, Inc. has experience with them both, so below are some items to note about ductless air conditioning repair in Atlanta versus a ducted system.

Differences Between the Systems

First, let’s take a look at some differences between the two systems:

  • The first (and most obvious) difference is that one system needs ductwork to function while the other does not.
  • The second difference is that the delivery system for the cool air in a ductless air conditioner happens via independent indoor air blowers; this automatically provides zoned cooling. To achieve zone cooling with a split-system AC, you would need to install a zoning system with the air conditioner.
  • Third, rather than having both an outdoor and indoor unit, a ductless air conditioner has an outdoor unit and indoor blowers.

Similarities Between Systems 

  • As stated above, both systems have an outdoor unit, and for both systems, these outdoor units contain the same components: a compressor, refrigerant and a condenser.
  • The indoor units, although different technically, are both responsible for blowing cold air into the property, and do so with the utilization of refrigerant and fans

Are the Repairs Very Different?

For the most part, the answer is no, the repairs are not very different between a ductless system and a ducted system. Each system needs annual maintenance, particularly for the outdoor unit, and each system can have problems with refrigerant leaks, electrical issues, fan issues, dirty filters and dirty coils.

A problem unique to a ductless system is when an inside blower hasn’t been properly mounted and begins to pull away from the wall or ceiling to which it’s attached. With ducted systems, the ducts can contribute their own repair-worthy issues, something that wouldn’t be a problem with a ductless system.

It’s hard to know what kind of repairs you may run into with ductless air conditioning in Atlanta, but rest assured that no matter what the repair, Air Conditioning Experts, Inc., is here to help you resolve them.

Condenser Problems with Your Air Conditioning

Monday, May 12th, 2014

The condenser is the outdoor section of your home’s air conditioning system. This cabinet contains a blower fan, the condensing coil, and the compressor; these components work together to release heat from inside your home to the outside. The compressor turns the liquid refrigerant into a hot, high pressure gas and sends it to the coil. The blower fan draws outside air across the condenser coil and the hot refrigerant inside, causing condensation that releases heat. The blower then exhausts this heat out of the unit, while the refrigerant moves through a line indoors to the evaporator unit.

If you keep your air conditioner properly maintained, the condenser should give you few problems. However, there are some malfunctions that can affect it, even with the best care. We’ll look at some of the more common condenser problems which will require you to call for professional repairs.

Look to Air Conditioning Experts, Inc. for the professional work on your air conditioning in Atlanta, GA that will restore your system to tip-top shape.

Some common condenser problems

  • Poor air circulation: For the condenser to work, it must receive free air flow into the cabinet. If the condenser originally received a proper installation from professionals, it should have enough open space around it (not pressed too close to walls). However, the area can become overgrown or filled with debris that will restrict airflow—or possibly even enter the cabinet and damage the components. To prevent this, make sure the condenser has a clear region around it, free from shrubs and rocks or any other possible obstruction.
  • Compressor seizing: The compressor operates like a piston engine, and can suffer from “tightness” if it loses lubrication or becomes dirty. This can eventually lead to the compressor “seizing,” and stopping altogether, which will also stop heat exchange. A repair technician will need to look into this and attempt to re-start the compressor. Do not attempt to run the AC when the compressor is having difficulty: you do not want the component to burn out.
  • Leaking refrigerant: The refrigerant lines in the compressor can begin to leak or come loose at connecting points. When this happens, the loss of refrigerant can seriously damage the compressor, and will lower the ability of the coils to absorb and release heat. You will often see evidence for this on the indoor evaporator coil: when ice starts to form across this coil, it may indicate a refrigerant leak. The leak must be sealed and the refrigerant recharged to its standard level.

Because the condenser houses the compressor—the most crucial component for AC operation and the most expensive to fix—it’s vital that you only allow licensed professional HVAC technicians to repair problems with it. The moment you notice issues such as low cooling power, loud sounds from the cabinet, or ice along the coils, call for skilled air conditioning repair in Atlanta, GA. You can reach the technicians at Air Conditioning Experts, Inc. 24-hours a day, so don’t hesitate!

How You Can Keep Cool While Waiting for AC Repair

Monday, May 5th, 2014

Although you can take steps to prevent your air conditioner from breaking down during a long summer season, sometimes you can’t avoid it—no machine is 100% invincible. We hope you won’t have to deal with emergency air conditioning repair in Atlanta, GA this summer, but if it should happen on one of the hottest days, contact Air Conditioning Experts, Inc. for fast service, around the clock, every day of the week.

While we’re rushing out to help you, you can keep yourself cooled down using a few handy methods. These won’t keep you as cool as a powerful central air conditioning system, but they will make the wait much easier.

Keeping cool in summer (when central AC isn’t an option)

  • Fans: You should have at least one standing or desk fan in your house ready to go to work when needed. Fans do not cool down rooms; they blow away the heat envelope around people to make them feel cooler. However, this can make a significant difference in your comfort. The best type of fans for a home are ceiling fans, which you should install in your home not just as a way to beat the heat in case of an AC failure, but as a way to reduce how much you need to us the AC. (For an extra cool kick, place a bowl of ice in front of a desk fan.)
  • Close the shades: Radiant heat from sunlight will contribute immensely to raising the temperature inside a home. When your AC is down, make sure the shades are down as well. Or the curtains. Or whatever you use to block the windows.
  • Turn off appliances and lights: Almost any appliance in your home will generate heat; shut off or unplug as many as you can. Turn off all but the essential lights. Also avoid using the oven or stove, or running the laundry machine or dryer.
  • Take a tip from the ancients: Ancient Egyptians cooled down rooms by hanging wet sheets or reeds across windows, which moistened and cooled the air. Hang up a few wet towels over open windows (ones facing away from the sunlight) and you’ll receive a similar benefit.
  • Drink plenty of cold water: Keeping properly hydrated is helpful to overcome the heat, and ice water will make you feel better in general. Avoid drinks with caffeine because they will dehydrate you.

Apply what you’ve learned every day

Once your air conditioning system is working once more thanks to skilled repair work, remember a few of these cooling tips to help you save energy during the rest of the summer. If you can cut back on your air conditioner use by an hour or so each day, you’ll see a noticeable reduction on your power bills for the season.

How Capacitor Problems Lead to Air Conditioning Repair

Monday, May 5th, 2014

The most common repair needs that air conditioners encounter are electrical ones. (If your air conditioner abruptly stops running, the first thing you should check is the circuit breakers; many times, the solution to the problem is as simple as re-setting a tripped breaker.) One of the key components of an air conditioner’s electrical system is the capacitor. In this post, we’ll look at what can go wrong in an AC when a capacitor begins to fail.

Repair needs due to failing capacitors are usually easy fixes for professionals—provided you catch the trouble in time and call trained technicians to do the work.

For fast and thorough air conditioning repair in Atlanta, GA, contact Air Conditioning Experts, Inc. We have 24-hour emergency service to keep your AC running.

Capacitor problems

A capacitor is a small cylindrical device that transmits electrical voltage to a motor. There are two types of capacitors in an air conditioning system: The start capacitor sends voltage to start the motor running. The run capacitor keeps the motor turning by transmitting voltage about 1.5 times higher than its nominal voltage. In an air conditioner, capacitors are connected to the motors that operate the indoor blower fan, the outdoor condenser fan, and the compressor.

If a capacitor begins to fail, it can lead to motors having difficulty starting or trouble continuing to run, and this can disable the two fans and restrict heat exchange and air distribution. But the most common issue that occurs from failing capacitors is “hard-starting” for the compressor. This is when the compressor begins to stutter when turning on, then runs for only a short time before shutting down once more. Whenever you notice this happening to your AC, call for repairs to look into it. Although failing capacitors are the most common reason for hard-starting, there are other possible causes that could result in damage to the compressor. Compressor repairs are among the most expensive for an air conditioner, so make sure you don’t hesitate when you need to call for repairs.

When capacitors are near to failing, they often make a noticeable clicking sound. This is a good alert that you need to have the capacitor replaced before it affects the performance of the air conditioner. Call on repair technicians to handle changing out the old unit for a new one; a compressor with the wrong voltage will make the air conditioner inefficient.
