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.
Routine maintenance involves replacing or cleaning the filters if so equipped, and keeping the outside air intake free of debris. After years of service the air exchanger will become crusted with grease and dirt that collects during condensation. Removing this accumulation will probably take solvents or degreasers and require opening up the cabinet and compartments.
In the UK, the Ozone Regulations came into force in 2000 and banned the use of ozone depleting HCFC refrigerants such as R22 in new systems. The Regulation banned the use of R22 as a "top-up" fluid for maintenance between 2010 (for virgin fluid) and 2015 (for recycled fluid). This means that equipment that uses R22 can still operate, as long as it does not leak. Although R22 is now banned, units that use the refrigerant can still be serviced and maintained.
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.
Ventilating or ventilation (the V in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.
This company was highly recommended to us by our realtor. Corey came out to do some work for us and he was really professional. He was on time, and explained everything he was doing and gave a quote (it actually ended up being cheaper!) before he started. He also looked at other stuff for us, and we got the feeling he was being honest and not pushy with his recommendations. We've already booked another appointment to fix some other things, and we requested Corey to do it.

I have no idea what a barrel is??? In chilled water systems the evaporator and condensers sometimes use what is called a chiller barrel for the evaporator and/or the condenser but for most residential system it is a rarity to find a chilled water system installed. Are you talking about a commercial system chiller. 7.1 KW is not a very big system but they do exist in light commercial and as mentioned in residential.

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.
Without proper ventilation, carbon monoxide can be lethal at concentrations of 1000 ppm (0.1%). However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in the blood, forming carboxyhemoglobin, reducing the blood's ability to transport oxygen. The primary health concerns associated with carbon monoxide exposure are its cardiovascular and neurobehavioral effects. Carbon monoxide can cause atherosclerosis (the hardening of arteries) and can also trigger heart attacks. Neurologically, carbon monoxide exposure reduces hand to eye coordination, vigilance, and continuous performance. It can also affect time discrimination.
Tony from HVAC came out on Sunday morning and did a fantastic job of immediately diagnosing the issue, quickly fixing the problem, and honoring the coupons I had. When I initially called on Saturday morning, I had a lot of trouble with their answering service getting their wires crossed with their technicians. However, Tony called me back and made it right. He even pointed out an issue that is in the horizon that I should look at (without charging me extra or telling me I had to fix it right now). Great service!
What type of insurance do you have? Heating, ventilation and air conditioning (HVAC) professionals work on a variety of mechanical areas of the home. You'll want to ask specific questions regarding professional training and licensing, as well as what types of insurance they have (for example, mold, air pollution or worker's compensation). It's fair to ask for the dollar amounts they are covered and a quality professional will show you verification of coverage.
AC air handler squealing or grinding noises. Though most air handlers have direct-drive motors, some older units may be belt-driven. Squealing sounds from a belt-drive air handler generally occur when the belt that connects the motor to the blower slips. In most cases, the belt is improperly aligned or worn and needs replacement. Follow the instructions above under Air Conditioner Not Blowing Air and refer to your owner’s manual.

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.
Many HVAC maintenance companies offer annual servicing contracts for preventative maintenance. Such contracts cost anywhere from $100-$150 per year, and cover annual visits in which standard maintenance tasks are performed. Some companies will allow you to make monthly payments for your maintenance contract, and will provide you with discounts around 15% if you hire them when you need your unit repaired.
AC units and thermostats have built-in delay features when they’re shut down and then repowered. The delay can be as long as 10 minutes. And, if you’ve subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you’ve installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn’t fire up after 30 minutes, it’s time to call a pro.
