If the unit isn't turning on, check on it outside to make sure the condenser is still running. It should be fully plugged in and the thermostat should be set. Lower the thermostat by a few more degrees than your typical setting. You should hear it power on after doing so. If that doesn't take care of the problem, check your fuse box. You could have a blown fuse or a tripped circuit that's causing the air conditioner to not turn on.
You should also have air ducts cleaned after recent water contamination or water damage to prevent mold; after renovations or remodeling to ensure debris and dust didn’t settle in the vents and ducts; if you are having problems with allergies or asthma; or when you are moving into a newly purchased home, especially if the previous owners smoked or had pets. The National Air Duct Cleaners Association (NADCA) recommends getting your air ducts cleaned every three to five years, or every two to three years in regions where homeowners use their air conditioning and heater for many months of the year, while the EPA suggests homeowners have duct cleaning done as needed.

An air conditioning system, or a standalone air conditioner, provides cooling and humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions. Outside, fresh air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Typical fresh air intake is about 10%.
An air conditioner’s cooling process produces condensation, which normally flows away from the equipment, causing no problem. If there is a clog in the condensate drain lines or drip pan, or if outdoor humidity levels are high, moisture may back up into your air conditioner. Excess condensation will increase indoor humidity levels and hinder the air conditioner’s performance. It could also cause damage to your air conditioner’s components.
In addition to air cleanliness, we provide expert services in air conditioning sales, installation, and maintenance, furnaces, heat pumps, packaged systems, and more.

Our technicians in Mableton will walk you through the service you need, how to fill your need most cost-effectively, and provide a 100% guarantee on the services we provide – each time.
If your air conditioner is old, consider buying an energy-efficient model. Look for the ENERGY STAR® and EnergyGuide labels — qualified central units are about 15% more efficient than standard models. New residential central air conditioner standards went into effect on January 1, 2015; see the efficiency standards for central air conditioners for details, and consider purchasing a system with a higher SEER than the minimum for greater savings.
Modern refrigerants have been developed to be more environmentally safe than many of the early chlorofluorocarbon-based refrigerants used in the early- and mid-twentieth century. These include HCFCs (R-22, as used in most U.S. homes before 2011) and HFCs (R-134a, used in most cars) have replaced most CFC use. HCFCs, in turn, are supposed to have been in the process of being phased out under the Montreal Protocol and replaced by HFCs such as R-410A, which lack chlorine. HFCs, however, contribute to climate change problems. Moreover, policy and political influence by corporate executives resisted change. Corporations insisted that no alternatives to HFCs existed. The environmental organization Greenpeace provided funding to a former East German refrigerator company to research an alternative ozone- and climate-safe refrigerant in 1992. The company developed a hydrocarbon mix of isopentane and isobutane, but as a condition of the contract with Greenpeace could not patent the technology, which led to its widespread adoption by other firms. Their activist marketing first in Germany led to companies like Whirlpool, Bosch, and later LG and others to incorporate the technology throughout Europe, then Asia, although the corporate executives resisted in Latin America, so that it arrived in Argentina produced by a domestic firm in 2003, and then finally with giant Bosch's production in Brazil by 2004.
After my initial meeting with HVAC Service I had really high hopes and thought these guys were going to be my HVAC go to company. However, it did not pan out this way whatsoever. Initial estimate meeting - This was the initial meeting I thought I found the go to company. Alberto was friendly, punctual, and knowledgeable. I asked some very basic questions and Alberto was able to explain the why's and why not's of each of my questions. Overall I felt really comfortable with Alberto and was extremely impressed. Then it goes all downhill..... Alberto said they were busy but could either install on the upcoming Saturday. We were going to be out of town and said unfortunately that day did not work. He then proposed the upcoming Tuesday as a possible solution, but just had to confirm with another appointment. I said great. I will review the estimate and call your office to confirm I want to move forward with the install. Within 1-hour of Alberto leaving (probably more like 30 minutes) I called the office to confirm I wanted to move forward with the install and to please confirm that Tuesday will be the install day. The lady on the phone said that she will get in touch with Alberto and call me back. This was on a Friday. On Monday I had not received a call from HVAC Service so I called to follow up. The lady on the phone said they were not able to secure a crane for Tuesday and that the install would not be taking place. Fine, no problem I understand. Two weeks go by and no phone call from HVAC Service regarding install date, or any update at all. I call them to check in to see if they have put me on the schedule and when I can expect to have the AC installed. You can tell by the discussion I had with the lady on the phone that they completely forgot about me and have not scheduled anything. She says she needs to get in contact with the owner because she has no idea on the availability of the crane. I was told that she would call me back by the end of the day with an update. Surprise, surprise, no phone call. I call to follow up at the end of the next day and she said that she has not been able to get in touch with the owner. By this time, I am starting to get frustrated because I am starting to get the run around. I question her if I am even on the schedule or if they attempted to schedule a crane. She says they are extremely busy and that she does not know. So I say, basically I have waited over 2 weeks and you have not put me on the schedule and I am at the end of the install line. No answer. I tell her to talk to her boss and find out what is happening, and I will think about what direction I want to move in at this point. Monday the following week, no phone calls, or follow up. I call to get an update and am told that they cannot install my system because they don't have time. I ask what does that mean, one year? One week? Until the end of summer they say. What does that mean I ask? They say at the end of September. I say thank you for wasting 1 month of my time. How could they have served me better without serving me? 1. Be honest and let me know as soon as possible that the install was going to be delayed and probably not happen until the end of summer. Don't waste a month of my time. I could have reached out to a different company in the time I was waiting for them. 2. Communicate! the thing that upsets me the most is I was the one making all the calls to them. Not once did they ever call me to say we have not forgot about you, or this is what is happening. 3. Provide recommendations on other contractors who could have helped me once they realized they were too busy. I am pretty disappointed it came to this review because I really liked this company and wanted to do work with them. It is a family run business, and reminded me of the HVAC business my dad owned. Beware once you are the one that has to start calling them for updates, or to follow up; your time is probably best served by calling a different contractor.
There is nothing worse than having your air conditioner break in the middle of a long, hot summer. You can ensure your air conditioning unit stays in working order all year long with regular service. Sometimes, however, repairs are necessary whether it’s fixing the evaporator, capacitor, or condenser or recharging the refrigerant. Most air conditioner repairs cost between $163 and $528 with most homeowners reporting that they spend about $344. If you do need a repair, here is some information to help you get it done quickly, professionally, and economically.

ISO 16813:2006 is one of the ISO building environment standards. It establishes the general principles of building environment design. It takes into account the need to provide a healthy indoor environment for the occupants as well as the need to protect the environment for future generations and promote collaboration among the various parties involved in building environmental design for sustainability. ISO16813 is applicable to new construction and the retrofit of existing buildings.
In the United States, HVAC engineers generally are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), EPA Universal CFC certified (for installation and service of CFC HVAC devices), or locally engineer certified such as a Special to Chief Boilers License issued by the state or, in some jurisdictions, the city. ASHRAE is an international technical society for all individuals and organizations interested in HVAC. The Society, organized into regions, chapters, and student branches, allows exchange of HVAC knowledge and experiences for the benefit of the field's practitioners and the public. ASHRAE provides many opportunities to participate in the development of new knowledge via, for example, research and its many technical committees. These committees typically meet twice per year at the ASHRAE Annual and Winter Meetings. A popular product show, the AHR Expo, is held in conjunction with each winter meeting. The Society has approximately 50,000 members and has headquarters in Atlanta, Georgia.
In very dry climates, evaporative coolers, sometimes referred to as swamp coolers or desert coolers, are popular for improving coolness during hot weather. An evaporative cooler is a device that draws outside air through a wet pad, such as a large sponge soaked with water. The sensible heat of the incoming air, as measured by a dry bulb thermometer, is reduced. The temperature of the incoming air is reduced, but it is also more humid, so the total heat (sensible heat plus latent heat) is unchanged. Some of the sensible heat of the entering air is converted to latent heat by the evaporation of water in the wet cooler pads. If the entering air is dry enough, the results can be quite substantial.
The use of CFC as a refrigerant was once common, including the refrigerants R-11 and R-12 (sold under the brand name Freon-12). Freon refrigerants were commonly used during the 20th century in air conditioners due to their superior stability and safety properties. When they are released accidentally or deliberately, these chlorine-bearing refrigerants eventually reach the upper atmosphere. Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radical. These chlorine radicals catalyze the breakdown of ozone into diatomic oxygen, depleting the ozone layer that shields the Earth's surface from strong UV radiation. Each chlorine radical remains active as a catalyst until it binds with another radical, forming a stable molecule and quenching the chain reaction.
In a thermodynamically closed system, any power dissipated into the system that is being maintained at a set temperature (which is a standard mode of operation for modern air conditioners) requires that the rate of energy removal by the air conditioner increase. This increase has the effect that, for each unit of energy input into the system (say to power a light bulb in the closed system), the air conditioner removes that energy. To do so, the air conditioner must increase its power consumption by the inverse of its "efficiency" (coefficient of performance) times the amount of power dissipated into the system. As an example, assume that inside the closed system a 100 W heating element is activated, and the air conditioner has a coefficient of performance of 200%. The air conditioner's power consumption will increase by 50 W to compensate for this, thus making the 100 W heating element cost a total of 150 W of power.
Not obvious is the fact that they need maintenance routinely, just like any other machine. The filter, usually located behind the front grill, needs to be washed. The condenser coil at the back of the unit can accumulate a lot of debris, and might require a special chemical bath. All air conditioning systems, large or small, need good air flow across the evaporator coil and the condenser coil. Efficiency and performance drop rapidly as air flow decreases. Lose enough air flow and the unit will burn out. Rodents can nest inside when not in use, and can foul up the unit in many ways. Wasps and hornets, as well as the honey bee find finned coils to be comfortable nesting places. Nests and dead insects can ruin the air conditioner.
Designed to improve manufacturing process control in a printing plant, Carrier's invention controlled not only temperature but also humidity. Carrier used his knowledge of the heating of objects with steam and reversed the process. Instead of sending air through hot coils, he sent it through cold coils (filled with cold water). The air was cooled, and thereby the amount of moisture in the air could be controlled, which in turn made the humidity in the room controllable. The controlled temperature and humidity helped maintain consistent paper dimensions and ink alignment. Later, Carrier's technology was applied to increase productivity in the workplace, and The Carrier Air Conditioning Company of America was formed to meet rising demand. Over time, air conditioning came to be used to improve comfort in homes and automobiles as well. Residential sales expanded dramatically in the 1950s.

Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off. Note that this may mean shutting off a circuit breaker that serves the furnace and air handler, and then, near the compressor, pulling out the disconnect block (or shutting off the 220-volt power) to the outdoor compressor.

We’ve found that many homes and businesses in Atlanta face significant indoor air quality issues as a result of the seasonal high humidity in our area, which creates conditions ripe for mold and mildew growth in both old and new HVAC systems. Our HVAC technicians can help you determine which strategies will work best for neutralizing airborne particulates in your home, which often involves a combination of filtration methods and ultraviolet light technology that together can help keep your system perpetually free of contaminants. We can also install whole-house dehumidifiers and humidifiers, which can make a huge difference in the amount of work your HVAC unit will have to do to be effective.
Special chemicals can be used to clean mineral deposits, but one of the safest is vinegar. A 50% mixture of vinegar and water will usually dissolve or help clean away deposits. If the humidifier has a drum with a belt, replacement of the belt at the beginning of the heating season can be the easiest fix if the water has a high mineral content. If the humidifier has screens or is the wick type, some corrosion can occur as well as build up
If your furnace needs to be repaired, you’ll want to find a qualified heating, ventilating and air conditioning (HVAC) repair technician. Each state has its own licensing requirements; some require all HVAC technicians to have an HVAC license, while others only require someone operating an HVAC service and installation company with employees to hold a contractor’s license. For example, in Alabama, the Alabama Board of Heating Air Conditioning, and Refrigeration Contractors regulates licensing, while in Kansas there is no state regulatory body and HVAC licensing can vary by region. For simple furnace repairs like changing out a filter, a trusted handyman can probably handle the job, but a trained professional should be hired for tasks like replacing a gas valve, installing a new inducer fan motor or other critical furnace repair jobs that involve dealing with gas leaks or other dangerous conditions.

Before we get into the different AC repairs and replacements that John Moore offers, it’s important to understand the basic operating principles of your AC system. There are two types of systems: electric and natural gas. Electric AC systems use an air handler to blow air through your home while natural gas systems use a furnace. Both furnaces and air handlers are typically located in the attic.
They were quick to come out and diagnose the problem with my furnace, but I thought the estimate of $549 a bit high to replace the circuit board. So called around and found Leo's Appliance in Concord that sells appliance parts and the circuit board was only $90.49 - that is the retail cost to me, so I imagine the wholesale cost is a lot less. So BEWARE of this company since they wanted $500!!! to replace the circuit board which is located right in the front of the furnace - extremely easy to access. I hate it that you cannot trust repair companies.
An important component of natural ventilation is air change rate or air changes per hour: the hourly rate of ventilation divided by the volume of the space. For example, six air changes per hour means an amount of new air, equal to the volume of the space, is added every ten minutes. For human comfort, a minimum of four air changes per hour is typical, though warehouses might have only two. Too high of an air change rate may be uncomfortable, akin to a wind tunnel which have thousands of changes per hour. The highest air change rates are for crowded spaces, bars, night clubs, commercial kitchens at around 30 to 50 air changes per hour.

A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
