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. 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.

"Friendly, professional, responded quickly to my problem. I have called many air conditioning companies about my problem including the maker of the unit and had come to the conclusion that I would not find someone to repair this unit. D's came in and within a short test found the problem and assured me of a fix. They made the fix within 2 days as they needed to get a part and they also checked to see what the cost would be of the fix by putting in the control boarrd from the maker which was very high to the extreme. I now have a unit working and am very pleased."

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.
Maintaining your air conditioner (HVAC) unit will ensure that it’s ready to properly cool your home all throughout the summer. Keeping your unit in good condition is also important for your wallet: lack of maintenance shortens a unit’s lifespan by 10-15 years, meaning you’ll need to buy a new one sooner. Lack of maintenance also results in a 5% efficiency loss, which results in higher energy bills.
If you need a furnace repaired or an air conditioner serviced, we'll send a local technician out to diagnose the specific problem and recommend solutions for you and your family. There will be a diagnostic fee for the visit, and any specific repairs will be an additional charge. If replacing your system is the best solution, the fee for the diagnosis will be credited toward the purchase and install of a new system.

Some systems include an "economizer mode", which is sometimes called a "free-cooling mode". When economizing, the control system will open (fully or partially) the outside air damper and close (fully or partially) the return air damper. This will cause fresh, outside air to be supplied to the system. When the outside air is cooler than the demanded cool air, this will allow the demand to be met without using the mechanical supply of cooling (typically chilled water or a direct expansion "DX" unit), thus saving energy. The control system can compare the temperature of the outside air vs. return air, or it can compare the enthalpy of the air, as is frequently done in climates where humidity is more of an issue. In both cases, the outside air must be less energetic than the return air for the system to enter the economizer mode.
The most recognized standards for HVAC design are based on ASHRAE data. The most general of four volumes of the ASHRAE Handbook is Fundamentals; it includes heating and cooling calculations. Each volume of the ASHRAE Handbook is updated every four years. The design professional must consult ASHRAE data for the standards of design and care as the typical building codes provide little to no information on HVAC design practices; codes such as the UMC and IMC do include much detail on installation requirements, however. Other useful reference materials include items from SMACNA, ACGIH, and technical trade journals.

BIG THANK YOU for being honest, and advising us that for some reason the fuse/switch was in the reverse position so the AC unit would not properly turn on. The unit turned back on immediately, and began cooling the house. And then providing advice that the AC/Heating system needed some TLC, and giving us options to save money by purchasing a maintenance plan that included the filters plus cleaning services since we were already being charged for the service today.
Change the filters regularly: This is one of the most important steps in system maintenance. Dirty filters mean your system has to work harder to move the air, causing poor performance and creating more wear and tear on the system. A clean filter also lowers your energy costs, since the system uses less power to do the same amount of work, and improves indoor air quality.

If you have an older central air conditioner, you might choose to replace the outdoor compressor with a modern, high-efficiency unit. If you do so, consult a local heating and cooling contractor to assure that the new compressor is properly matched to the indoor unit. However, considering recent changes in refrigerants and air conditioning designs, it might be wiser to replace the entire system.

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
