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.

We live in a recently completed townhouse that was built with double-wall construction. That construction method was touted by the builder as what would keep sound from penetrating between the units. But we can hear the next door neighbors' TV and stereo, and sometimes voices and even snoring, through the wall. While sometimes it's the volume, mostly it's the bass sounds coming through the wall. They say they don't hear us, but we keep our bass turned down. They crank up the bass, and they are not going to change that. They also are not going to do anything construction-wise to help from their side. What is the best way for us to try to block the low frequency/bass sounds from penetrating the existing wall into our side?

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.
Tony was very good - appointment took a while to book, but that's understandable, since they have built a great business and have lots of people calling them. Tony came this Sunday morning, and once he saw the HVAC unit, knew exactly what the issue was - fixed it in under 20 mins, and my AC was back to normal Pricing is fair - parts, labor and diagnostic fee and tax I would definitely recommend him to anyone needing his services. He's honest, very nice to deal with even made my toddler son smile. 5 STARS ALL THE WAY!
In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate. In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida. He hoped to eventually use his ice-making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities. Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1851 for his ice-making machine. Though his process improved the artificial production of ice, his hopes for its success vanished soon afterwards when his chief financial backer died and Gorrie did not get the money he needed to develop the machine. According to his biographer, Vivian M. Sherlock, he blamed the "Ice King", Frederic Tudor, for his failure, suspecting that Tudor had launched a smear campaign against his invention. Dr. Gorrie died impoverished in 1855, and the dream of commonplace air conditioning went away for 50 years.
Engineers have pointed out some areas where efficiency of the existing hardware could be improved. For example, the fan blades used to move the air are usually stamped from sheet metal, an economical method of manufacture, but as a result they are not aerodynamically efficient. A well-designed blade could reduce electrical power required to move the air by a third.

Hii need you guys help! Once my thermostat drop below the set temp , my furnace does not turn on and I was wondering what’s wrong with it. It happens mostly on cold nights. Sometimes I would have to go in the basement and turned the furnace power switch off then on and will come on once I switch it off then on.i also change the thermostat recently, so I don’t think that’s the problem
Poorly maintained water cooling towers can promote the growth and spread of microorganisms, such as Legionella pneumophila, the infectious agent responsible for Legionnaires' disease, or thermophilic actinomycetes. As long as the cooling tower is kept clean (usually by means of a chlorine treatment), these health hazards can be avoided or reduced. Excessive air conditioning can have a negative effect on skin, causing it to dry out, and can also cause dehydration.
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. So if money is not a concern for you give them a call as they very prompt and professional and others have been happy with their service
