Many people don’t even realize they have an issue with a central air conditioning system until it breaks down. Fortunately, regular maintenance can remove much of this uncertainty and avoid the frustration of being stuck in 90-degree heat while waiting for an HVAC technician. Although a professional, regular servicing schedule is recommended for optimum performance, there are some basic maintenance tasks that can help ensure that your system operates correctly.
Checking for Freon Leaks:
One of the most common causes of a non functioning air conditioning unit is the need for a Freon charge. Air conditioning systems are designed to function for many years without needing to be charged. The Freon level inside your system has been carefully calibrated to ensure optimum performance; too low and the system cannot cool properly, too high, and the internal pressure will be too great and damage the compressor. The only reason your system would need a Freon charge is if it has developed a leak. Signs of a leak include poor AC performance, icing up of pipes or greasy spots under pipes, joints, and other system components. While you would need professional assistance to recharge the Freon, if you can point out a leak it will save time.
Check the Thermostat:
Another common cause of air conditioning failure is a fault with the thermostat. A faulty thermostat can cause the system to operate erratically, as the ambient temperature inside the home is gauged incorrectly. Checking the thermostat is relatively simple. First, check that the readout is a match for the ambient temperature inside your home. Alter the settings and verify that the changes are made to the temperature. It is also worth checking that your timer settings are still applicable. There is no point in having your air conditioning turn on and cool the house when no one is home.
Check for Obstructions:
Dust, lint, insect nests, mice nests and other debris can accumulate inside the ducts, vents and hoses of your AC system causing an obstruction. This can not only restrict the airflow, but can also encourage the growth of mildew and mold. Check the vents and filters to see if they are clear. Also, check the outdoor condenser unit to ensure that it is free of leaves, vines, and other garden debris.
Change Your Filters:
Finally, you should establish a routine of changing the filters in your air conditioning system. Most manufacturers recommend that filters are cleaned or changed every eight to twelve weeks. If you have pets, smokers or allergy sufferers in your home, you may find that you need to change your filters more frequently. Clogged filters can compromise the air quality inside your home and trigger the safety cut off on your system. The full details on how to change the filters in your system will be detailed in your owner’s manual.
Although a professional annual service can keep your system running in optimum condition, it is important not to neglect basic maintenance between visits. With a little care and attention, you will reduce the risk of suffering the frustration and inconvenience of a system breakdown.
