How DOES your AC work???

Central Air ConditioningThanks to the second law of thermodynamics, air conditioners make hot, stuffy rooms comfortable, but technically they don’t cool the air. “An air conditioner works like your refrigerator,” says Scott Needham, president of Princeton Air in West Windsor.“It moves heat from one space to another.” According to the second law, when solids, liquids, or gases of different temperatures meet, heat shifts from the warmer to the cooler until they reach the same temperature, or equilibrium. People used to effect heat transfer, as it’s called, by blowing hot air across blocks of ice or towels soaked in ice water. It worked but required massive amounts of ice or cold water.In July 1881, for example, when President James Garfield, shot by an assassin, lay dying in Elberon for over two months, doctors went through 250 tons of ice to cool his room.Then, in 1906, New Yorker Willis H. Carrier patented an “Apparatus for Treating Air,” initiating the age of air conditioning. In 1915, Carrier formed the company that still bears his name. Early units were massive, costly, and—because they used toxic ammonia or sulfur dioxide as a refrigerant—dangerous. Then came Freon, which had environmental problems. Early forms of Freon have been replaced by green HFCs. Apart from…

Is your AC unit blowing hot air?

AC blowing hot or warm air? Want to figure out what the problem is before calling an air conditioning professional? This article is for you. While there are many, many reasons your air conditioner is blowing hot air, we’ll run through the most common causes that you can fix or diagnose on your own.  If you need immediate help, give us a call at (305) 791 5020  Thermostat Settings:  Is the thermostat set incorrectly?  It may sound silly, but we’ve seen it happen before. Double-check your thermostat and make sure it isn’t set to “heat”. It may have been bumped by someone else in the home. Also, check to see if you have your thermostat set to “auto” or “on”. If it’s set to “on”, that means the fan will blow even when the air conditioner isn’t actually cooling. This causes your AC to blow out warmer air out the vents when the outside unit isn’t running. There’s a restriction in airflow A restriction in the airflow to and from your air conditioner often results in not enough air coming out of the vents to cool your home. Restricted airflow can also cause the compressor (the part that moves the refrigerant) in your air conditioner’s outside unit to freeze up.  This…

First, turn the temperature down a few extra degrees to get your home as cool as possible before you have to turn the system off. As the hurricane approaches, you should turn the air conditioner off by cutting electricity to this appliance. This will protect it from electrical surges during the storm. Don’t turn the AC unit back on until the storm has passed and you’ve carefully inspected it for any signs of damage. CALL TODAY for more information 305 791 5020
