The 2nd-century Chinese mechanical engineer and inventor Ding Huan of the Han Dynasty invented a rotary fan for air conditioning, with seven wheels 3 m (10 ft) in diameter and manually powered by prisoners of the time.[6] In 747, Emperor Xuanzong (r. 712–762) of the Tang Dynasty (618–907) had the Cool Hall (Liang Dian 涼殿) built in the imperial palace, which the Tang Yulin describes as having water-powered fan wheels for air conditioning as well as rising jet streams of water from fountains. During the subsequent Song Dynasty (960–1279), written sources mentioned the air conditioning rotary fan as even more widely used.[7]
Once a diagnosis is made to your air-conditioning and/or heating system, the unit can be repaired, in most situations, with stock HVAC parts off the truck. Sometimes the HVAC part has to be ordered because it is a specialty part that only the HVAC manufacturer of your equipment can provide. If the part can be picked up locally then you can expect to pay for travel time to and from the HVAC parts dealer. It is practically impossible to carry every single HVAC part for every single HVAC breakdown that occurs.
Ductwork pinging or popping. If you hear a pinging or popping sound coming from metal ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal. Track along the duct runs, listening for the sound. If you find it, make a small dent in the sheet metal to provide a more rigid surface that’s less likely to move as it heats and cools.

For residential homes, some countries set minimum requirements for energy efficiency. In the United States, the efficiency of air conditioners is often (but not always) rated by the seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner. The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours (W·h) during the same period.[33]

The Refrigeration Loop is a closed system and refrigerant should never have to be added to the unit unless there is a leak. Most residential units use R-22/R410A refrigerant. Prices of R-22/R410A are rising every year as we get closer to the date when refrigerant manufacturers will no longer be able to make R-22/R410A. Phase-out of R-22, an HCFC, begins in 2010 and expected to be complete by 2020.). Furthermore, make sure you ask what the service company charges for R-22 when you are calling an HVAC contractor.

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.
Your system is 10 - 15 years old: Follow this simple rule of thumb from Energy Star—if your current system is over 10 years old, it's time to start looking into an HVAC replacement. Most HVAC systems last for about 15 years, so there’s no immediate need to replace yours if it’s still functioning properly. But by doing your research now, you’ll know just what you want to do should your HVAC system suddenly stop working properly.
Refrigeration air conditioning equipment usually reduces the absolute humidity of the air processed by the system. The relatively cold (below the dewpoint) evaporator coil condenses water vapor from the processed air, much like an ice-cold drink will condense water on the outside of a glass. Therefore, water vapor is removed from the cooled air and the relative humidity in the room is lowered. The water is usually sent to a drain or may simply drip onto the ground outdoors. The heat is rejected by the condenser which is located outside of room to be cooled.
CIBSE publishes several guides to HVAC design relevant to the UK market, and also the Republic of Ireland, Australia, New Zealand and Hong Kong. These guides include various recommended design criteria and standards, some of which are cited within the UK building regulations, and therefore form a legislative requirement for major building services works. The main guides are:

Energy efficiency can be improved even more in central heating systems by introducing zoned heating. This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is very critical to maintaining a proper temperature.
This problem can be caused by an air-conditioning system that is too large for the house. If your system has always failed to dehumidify adequately, and it commonly short cycles (turns on and off frequently), an oversized system is ​a likely cause. An oversized system can cool the air so fast that the thermostat shuts off the system before much of the humid air has made its way across the cooling coil to get dehumidified. 
Technicians who specialize in new installation work may experience periods of unemployment when the level of new construction activity declines. Maintenance and repair work, however, usually remains relatively stable. Business owners and homeowners depend on their climate-control or refrigeration systems year round and must keep them in good working order, regardless of economic conditions.
Check that the 240-volt circuit breaker (double-pole breaker) controlling the air-conditioning compressor/condensing unit and the 120-volt circuit breaker controlling the furnace blower or separate air handler, is in the "On" positions. If a circuit breaker has tripped or a fuse is blown, then reset the circuit breaker or replace the fuse. If you reset the breaker or replace the fuse and they trip or blow again, stop and call an air-conditioning service technician, as you may have a more serious problem.
Low refrigerant charges take away from the life of the compressor. The compressor is cooled from the return refrigerant vapor. When there is a low charge there are fewer vapors to cool the compressor, therefore it runs hotter. Any compressor (or electric motor for that matter) which runs above the recommended temperature range will have a shorter life span and cost more to operate.

In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, (de-)humidification, cooling, cleaning, ventilation, or air movement). In common usage, though, "air conditioning" refers to systems which cool air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.[3]

Dehumidification (air drying) in an air conditioning system is provided by the evaporator. Since the evaporator operates at a temperature below the dew point, moisture in the air condenses on the evaporator coil tubes. This moisture is collected at the bottom of the evaporator in a pan and removed by piping to a central drain or onto the ground outside.

As you would expect, air conditioning in Portland isn't as expensive as in most areas of the country, owing simply to the fact that most homes don't require particularly large or state-of-the-art units. While our data suggests the national average for air conditioning installation is about $6,000, in Portland we see numbers between $3,000-$4,000, although we've also seen projects as low as $1,500 and as high as $6,000. Heat pump installation is likely to be closer to the national average, but as mentioned, these devices work to be cool your home in the summer and heat in the winter.
Packaged terminal air conditioner (PTAC) systems are also known as wall-split air conditioning systems.[36] They are ductless systems. PTACs, which are frequently used in hotels, have two separate units (terminal packages), the evaporative unit on the interior and the condensing unit on the exterior, with an opening passing through the wall and connecting them. This minimizes the interior system footprint and allows each room to be adjusted independently. PTAC systems may be adapted to provide heating in cold weather, either directly by using an electric strip, gas, or other heater, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air conditioner into a heat pump. While room air conditioning provides maximum flexibility, when used to cool many rooms at a time it is generally more expensive than central air conditioning.

Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits. In more complex schemes, warm air is allowed to rise and flow out high building openings to the outside (stack effect), causing cool outside air to be drawn into low building openings. Natural ventilation schemes can use very little energy, but care must be taken to ensure comfort. In warm or humid climates, maintaining thermal comfort solely via natural ventilation might not be possible. Air conditioning systems are used, either as backups or supplements. Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate.

If so, you may want to consider replacing your entire AC system. After your AC system reaches a certain age, it makes more sense to invest in a new AC system altogether rather than repairing it one piece at a time. To learn more about John Moore’s AC replacement program, our warranty, and the cost-advantages of replacing your AC system, visit our AC Replacement page.
In order to get the most out of your equipment, we highly recommend proper preventative HVAC maintenance. You’ll want to make sure from the outset that you have access to skilled and knowledgeable technicians who have been factory-trained to service your particular model, since different systems require different highly specific modifications. It’s advisable to find a reputable HVAC dealer in the Atlanta area that guarantees their work and offers annual service contracts to their customers to ensure necessary seasonal maintenance is always being performed regularly. Many times, timely adjustments and filter changes that are done on a regular basis can wind up saving you from breakdowns that always seem to occur right when you need your system the most.

A heating, ventilation and air conditioning (HVAC) service technician starts an appointment with a customer by asking about any problems with the heating, ventilation, and/or air conditioning systems in the client's home or business. From there, the technician will carefully examine the equipment in question to diagnose and troubleshoot the problem. Once the issue is determined, the technician provides the customer with a repair quote and, if authorized, begins to repair or replace defective equipment, mechanical components, or wiring in HVAC systems. An HVAC service technician might also be called upon by a customer to carry out preventative maintenance tasks or inspections to ensure that heating, ventilation, and air conditioning systems continue to run smoothly. A technician should have certification or an associate's degree from a technical or trade school that is accredited by HVAC Excellence, the National Center for Construction Education and Research, or the Partnership for Air Conditioning, Heating, and Refrigeration Accreditation. Formal training programs can last anywhere from six months up to two years. The job involves working with electrical equipment, so it is very important that a technician know exactly what he or she is doing or the job can get very dangerous very quickly. If an education is not in the picture, it is sometimes possible to go through a formal apprenticeship program which can take three to five years and mixes on-the-job experience and training with classroom instruction. Exams for certifications are offered by a number of associations. A license to work as an HVAC technician is required in several states and can be obtained by passing a written test.

In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York.[citation needed] After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.[citation needed]
Was not satisifed with this company.  This person came out and took 10 minutes only to tell me that my unit would not last for a year and that I needed to have it replaced!  I'm not sure if he was very knowlegable or if he was just plain lazy and do not even try to fix the problem.  He just wanted to install a brand new system because he was both and of course, that's much more money for him!
I awoke to a smoky smell from my heater and called HVAC service Heating & Air . I called HVAC and I was given an appointment that afternoon. Their technician arrived promptly and was totally knowledgeable and courteous. He had the new motor and starter on his truck and after a total replacement I now have my morning heat back!! I would use them over n over and they were very competitive in their pricing.
In addition to the information below, see these two articles for the general care and maintenance of your air conditioner: Preparing Your Air Conditioner for Summer and How to Replace Furnace & AC Filters. Most noteworthy, you should replace the filters at least twice a year, before the heating and cooling seasons. For information on furnace problems, please see Furnace Not Working.

You have an incredible team! My suite has had major issues constant backups. In the last few months we had a horrible flood that caused us thousands of dollars in repairs. Your team was so attentive and took care of all the repairs. Just yesterday another back up called them immediately and like quick responders they were there to take of it! A huge thank you from my La Costa providers and staff! We appreciate your hard and dedicated work!


An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. Check out our Energy Saver 101 Infographic: Home Cooling for more ways to help improve your comfort and the efficiency of your air conditioner.
I have a recurring problem of having to have freon added to my A/C system. I have even replaced both units inside and outside but seem to have the same problem. I believe that it must be in the lines between the outside and inside. Is there anything that can be put into the lines to seal any leaks if this is the problem? If not is it advised that the lines be replaced?

The Environmental Protection Agency (EPA) requires that all technicians who open a system containing a controlled refrigerant be certified to do so. There are four levels of certification, one of which is a “universal” certification to allow the HVAC technician to work on any type of equipment containing refrigerant. Your HVAC technician should be certified as “Level II Certified” at a minimum or, preferably, “Universal Certification” to work on your central air conditioner. Obtaining this certification information from your professional HVAC technician may be required in the event you are working with a realtor to sell your home. Costs for certification average $40-$240.
1) Your air conditioner is not working at all. Before calling in a professional to address this issue, you may want to check a few things yourself. Check to see if your thermostat is set to “cool”. Confirm that your designated cooling temperature is less than the temperature of the room or home. If everything is set correctly, check the electrical panel to be sure you do not have a tripped breaker. If these things all check out and your air condition unit is still not working, it is time to call in a professional.
Technicians who specialize in new installation work may experience periods of unemployment when the level of new construction activity declines. Maintenance and repair work, however, usually remains relatively stable. Business owners and homeowners depend on their climate-control or refrigeration systems year round and must keep them in good working order, regardless of economic conditions.

For residential homes, some countries set minimum requirements for energy efficiency. In the United States, the efficiency of air conditioners is often (but not always) rated by the seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner. The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours (W·h) during the same period.[33]
With the split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that short lengths of duct handle air from the indoor unit to vents or diffusers around the rooms.
An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. Check out our Energy Saver 101 Infographic: Home Cooling for more ways to help improve your comfort and the efficiency of your air conditioner.

Heat pumps and electric furnaces usually have steam humidifiers to increase output. They are line voltage powered and must be unplugged or disconnected before servicing to avoid injury. With the exception of some mist type humidifiers, all have a reservoir. Stagnant water sitting in the reservoir during the off season can be a breeding ground for bacteria. Turn the water off and clean the humidifier if possible when heating season has ended.
HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, on ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
Reinstall the access panel and disconnect block. Turn on the circuit breaker and furnace switch. Then set the thermostat to a lower temperature and wait for the AC to start (see “Be Patient at Startup,” below). The compressor should run and the condenser fan should spin. If the compressor starts but the fan doesn’t, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor (photo 7). Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts. If it doesn’t, you’ve given it your best shot—it’s time to call a pro.
