You might have the ability to fix your air conditioner on your own. Here are some things to take into consideration before you call an air conditioning repairman to guarantee you do not get an $80 or $100 fee for a slight problem. These are all simple steps that any home owner can easily take to locate and repair a slight A/C complication that is keeping your system from cooling.
Many individuals think that by turning their systems off and permitting their residences to get hotter during the day, they are causing their systems to run less and are as a result, saving money, however, this is not the case. The problem is that air is not the only thing that heats up when you do this; furniture, carpeting, walls, etc. will also heat up. When you get home and turn your air conditioner back on, it actually has to work harder and longer to get rid of all the added heat and bring the temperature down to a comfortable degree.
Keep your doors open as much as possible. A properly set up and balanced air conditioning system is designed to deliver and return warm or cold air evenly to and from all spaces in your home. Closing doors and supply vents, however, can easily interrupt this balance and cause particular spaces to become hotter or colder than others, resulting not only in discomfort, but also in reduced effectiveness. It also causes air pressure to increase in your ductwork, which could potentially cause or magnify air leaks, again, decreasing the effectiveness. Doors to unused spaces can be closed as long as there is enough area under the door to permit air circulation; thick carpeting which brushes against the bottom of the door creates a seal of sorts. If you do choose to close off a few of your supply registers, never close off vents to more than 10% of your total air conditioned area.

When room temperatures drop lower than the set temperature on the thermostat, it usually implies that the thermostat is incorrectly calibrated or set up where it doesnt sense a proper sampling of room air.
Change your filters frequently. This is one of the most simple, yet most frequently neglected methods of helping to keep your HVAC system in its best working condition. A filthy filter will restrict air flow to your system, decrease the quality of the air in your home, and cause your system to be ineffective by permitting the interior of the air handler to become dirty too. In some cases, major damage to your HVAC system and your home can be caused simply because of a plugged-up filter.
