James Harrison's first mechanical ice-making machine began operation in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Australia. His first commercial ice-making machine followed in 1853, and his patent for an ether vapor compression refrigeration system was granted in 1855. This novel system used a compressor to force the refrigeration gas to pass through a condenser, where it cooled down and liquefied. The liquefied gas then circulated through the refrigeration coils and vaporized again, cooling down the surrounding system. The machine produced 3,000 kilograms (6,600 lb) of ice per day.
In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids (such as alcohol and ether) could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to speed up the evaporation. They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that, soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about 6 mm (1⁄4 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin concluded: "From this experiment one may see the possibility of freezing a man to death on a warm summer's day."
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?

Inside the unit, the air passes over the evaporator coil first, and is cooled and dehumidified. The now dehumidified, cold air then passes over the condenser coil where it is warmed up again. Then the air is released back into the room. The unit produces warm, dehumidified air and can usually be placed freely in the environment (room) that is to be conditioned.
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.
A mini-split system typically supplies air conditioned and heated air to a single or a few rooms of a building. Multi-zone systems are a common application of ductless systems and allow up to 8 rooms (zones) to be conditioned from a single outdoor unit. Multi-zone systems typically offer a variety of indoor unit styles including wall-mounted, ceiling-mounted, ceiling recessed, and horizontal ducted. Mini-split systems typically produce 9,000 to 36,000 Btu (9,500–38,000 kJ) per hour of cooling. Multi-zone systems provide extended cooling and heating capacity up to 60,000 Btu's.

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.
If you have a good HVAC contractor they should offer an annual preventive maintenance agreement where they will perform semi-annual maintenance, once in the Spring and once in the Fall, to service your heating and cooling system. The typical maintenance agreement usually guarantees the HVAC contractor will provide service and parts at a discount rate if the listed equipment fails. Some contractors will even give you after hours service with no extra overtime charge as is the case with most other customers.
My A/C went out on a Friday and I found this company in the phone book on Saturday morning. They came out just a few hours later and it was decided that I needed a new system. The pricing was good as well as the customer service. They brought me a temporary portable air conditioner for Saturday night and they replaced my system on Sunday. This company has the best customer service of any business that I have dealt with. I would highly recommend this company to anyone and have. Great Company!!!!!
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.
