Air Conditioning Blog Chicago News

This month’s troubleshooting situation centers around a very recently installed heating and cooling system, and a customer who has called to complain that certain rooms in the house “just don’t seem to be getting enough air.”

(Before we begin with the specific troubleshooting information on this situation, we’ll establish a couple of points… First, the problem isn’t related to the refrigeration system in any way, and second, there are no electrical problems contributing to the complaint. In this situation, we’re dealing with an airflow problem. Note that Figure 1 shows the design of the supply duct system exactly as it appears in the attic crawl space.)

When you arrive at the customer’s home, you find that the two rooms the customer is complaining about are closest to the air-handling unit in this duct system that employs one central return and an extended plenum system on the supply duct assembly. In assessing the situation, you determine that the airflow from each supply register in these two rooms should be approximately 120 cfm, but when you measure the airflow with a digital velocity meter, you find the airflow to be approximately 90 cfm. As your next step, you move on to the crawl space to check the supply ductwork and find no leakage or crushed duct, but you do find, as we mentioned above, the supply duct system in Figure 1.

Your troubleshooting problem: What design flaw is responsible for the specific airflow problem we’ve described in this situation?

In Burbank ,IL Most central air conditioners are connected to a home’s forced-air distribution system. Thus, the same motor, blower, and duct work used for heating are used to distribute cool air from the air conditioning system. When a central air conditioner is operating, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn’t cool, especially during humid summer evenings the problem is probably in the distribution system meaning high  humidity, low air flow, dirty filter or evaporator coil, possibly a loss of freon charge. In Burbank, Illinois there`s only one name to turn to for your a/c tune-up or evaluation and that’s us here at Around The Town Heating and Air Conditioning. Call today 708-388-2247

Residential a/c repairs are some what confusing , the a/c Chicago was working last night when we went to sleep , when we woke up we were sweating terribly, Why?  A/c  systems aren`t  that complicated if you think about how a/c `s work.  Answers to questions why the a/c `s work one minute then quit, is no different then any mechanical machinery that requires maintenance.  Air conditioning Chicago requires 3 basic items to run properly, the most critical is air flow both across the condenser as well as through  the furnace or air handler. Air flow restrictions can consist of a dirty condenser or a evaporator coil, a restricted air filter, low air flow from a defected condenser fan motor or furnace/ air handler blower motor. The second reason can be low on freon, now if your system has been there for a awhile and operated OK then its a good possibility a freon leak may have recently occurred, possible leak sites are in the evaporator coil or out by the condenser unit Chicago, maybe your refrigerant lines run through the walls and a screw or nail penetrated the refrigerant line, metal objects over years and with friction may have been the culprit, it happens. The third item just may be plain old mechanical failure of the compressor or some other electromechanical items. Central air conditioning or a/c systems Chicago should be maintained by licensed professionals with a EPA certificate or Nate certified annually and by doing so you make catch a problem and fix it before the 95 degree days hit. Always Call Around The Town Heating And Cooling for your servicing of your a/c system. 312 243-9896

Cooling Tips

• Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic. They are effective when operated at night and when the outside air is cooler than the inside.
• Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
• Don’t set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
• Set the fan speed on high except in very humid weather. When it’s humid, set the fan speed on low. You’ll get better cooling, and slower air movement through the cooling equipment allows it to remove more moisture from the air, resulting in greater comfort.
• Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.
• Don’t place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
• Plant trees or shrubs to shade air-conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.

THERE ARE MANY HEATING AND AIR CONDITIONING COMPANIES OFFERING FREE FURNACES WITH A PURCHASE OF A AIR CONDITIONER*

THINK ABOUT THAT STATEMENT LOGICALLY, TO GET A FREE FURNACE WITH A PURCHASE OF A CENTRAL AIR CONDITIONER YOU WILL HAVE TO DIG DEEP IN YOUR POCKTS TO GET THAT SPECIAL. IE TO RECIEVE THE ABOVE YOU WILL HAVE TO BUY THE MOST ENERGY EFFICIENT CENTRAL AIR CONDITIONER ON THE MARKET LIKE A 22 SEER 410A TWO STAGE ,THE COST OF SUCH PRODUCTS ARE OVER WELMING AND THE ENERGY SAVING IN THE LONG RUN DOES NOT WARRANT SUCH A PURCHASE UNLESS YOUR POCKETS ARE DEEP AND MAKING A PURCHASE LIKE THIS MAKES YOU FEEL ALL WARM AND TOASTY AND THEN THE CONTRACTOR WILL GIVE YOU A FURNACE FOR FREE BUT NOT THE COST OF INSTALLATION OR THE ADDITIONAL PARTS TO INSTALL IT. OTHER GIMMICKS LIKE WE WILL BEAT ANY COMPETATORS PRICE BY $ 500.00 MAY SOUND GOOD BUT ARE THEY COMPARING APPLES TO APPLES? I HIGHLY DOUBT IT. MY THOUGHTS AS A OWNER OF A HVAC CONTRACTING FIRM IS YOU GET WHAT YOU PAY FOR, WHOEVER IF YOU THE CONSUMER DON`T KNOW THEN MY ADVICE IS TO GET 3 QUOTES OF THE SAME EXACT EQUIPMENT AND THEN YOU WILL SEE WHERE THE DYING DOGS LIE. GOOD LUCK AND THANKS FOR LISTENING. ED
