When the air conditioner fails to serve us during the hot summers we first panic and then rush to an HVAC (heating, ventilation and air conditioning) technician. This leads us to spend few hundreds of money on repairs. But if an ordinary man is comfortable working around the electricity and is willing to spend less money on the parts then he can probably repair his own air conditioner. This way the work can be done within few hours and the labor cost is not there.
A normal air condition service system is made up of two major components. They are the condensing unit which is always present outside the house and the evaporator coil that is in the plenum of the furnace or the air handler.Any person can check on the internet about the best do it yourself (DIY) AC repairing and maintenance tips. These tips will help him to repair the most common air conditioning problems which is the ‘low cooling’ or the ‘no cooling’ problem. Few things are perfectly necessary to do the work, which is not at all expensive; those are a multimeter, an assortment of screwdrivers, a voltage sniffer and a socket set.
Parts required– the contactor (relay) and the start or the run capacitor fails most of the time and these parts are inexpensive. So it is better to buy and install these parts right away, especially if the AC is older than 5 years. The condenser fan motor can also fail. To buy the parts which need for repairing you can replace the nameplate on the condensing unit (but not on the furnace). Write down the model or the serial number. The best way is to take a photograph. The parts are easily available in an appliance store or with a furnace dealer.
Since the temperature stays quite high in Houston, Texas ACs are a common thing there. Every household has one or two ACs with them. Any common man staying here can take out some time to repair their own house AC. Firstly try to set the thermostat to the AC mode and then lower the temperature. If the furnace fan kicks in then be sure that the problem is not with the furnace. Then check the fans, if the fan does not run, try to reset the furnace circuit breaker. Even if the fan does not start that’s the time when you need to call a professional person who can understand the problem. Even AC man of Houston is easily available. Just give a call to any AC repair shop of Houston they will come immediately. In fact, they provide service 24*7 during summer days.
A caution– always turn off the AC and the furnace breakers in the main electrical panel even before pulling the outdoor disconnect or removing the condensing unit’s access panel. To be more sure use a voltage tester on the wires coming into the contractor and see whether the power is really off or not.
